Innovation

SPECIFICATIONS

For over 65 years, the name Titus has been synonymous with innovation in commercial air distribution. Many of the solutions we have developed over the years are still tried and true core products in our industry today. Intelligent Innovations speaks to our ability to solve problems and look at air distribution in new ways. Our true passion, however, lies in our ability to find clever and creative ways to enhance occupant comfort. Clever. Creative. Comfort. Several examples can be found within the pages of this catalog, and one of the stand-out products is the EOS; the industries first solar-powered, energyharvesting auto-changeover diffuser. Not only does the EOS provide THE solution for perimeter heating and cooling challenges, but it decreases the time it takes for an occupied zone to reach the setpoint, over the traditional split compromise diffuser, to improve occupant comfort. Additionally, the technology at work in the EOS provides us with a scalable energy

CORPORATE VALUES

harvesting platform to use as a jumping off point to address thermal comfort in revolutionary ways. Another cleaver and creative example innovation from Titus is the Plexicon. Displacement ventilation, while a great solution for cooling a space, usually requires a separate or supplementary system for heating; which affects the design, installation and overall cost of a project. The Plexicon addresses this challenge by incorporating displacement cooling and mixedairflow heating into a single diffuser assembly with auto-changeover action. Providing both cooling and heating from the same diffuser eliminates the need for a secondary heating system, reduces overall project costs, and delivers a high level of thermal comfort to the building occupants. At Titus, we are continually working on developing new ways to advance the science of air distribution.

Green Building design and energy conservation concepts are not new, yet in recent years the focus throughout the world has been to build structures with these principles in mind. We have seen the positive impact that designing and creating green buildings with these concepts have on our community and more importantly the world in which we live. As such, 100% of our focus for the past couple years and going forward has been on developing and delivering Green Solutions, and not just any Green Solution, but relevant Green Solutions. This is exactly the purpose of the Titus Energy Solutions website. The Energy Solutions micro-site is a first of its kind for any HVAC manufacturer in the industry. Our tagline, The Leader in Air Management is not just words. Titus is fully committed to provide the latest innovations to the HVAC market and this new website is just another piece to an ever-growing puzzle. By being singularly focused on Green products and Green Building CORPORATE VALUES

concepts, this website provides a portal into the latest developments in training, design, energy conservation, and news that directly affect us. We made every effort to incorporate all the tools needed to find the perfect Green Solution. Within the site you will find relevant product information, marketing collateral, LEED tools and other energy conservation related resources. We offer a wide array of Green products that can be used in a variety of applications. Whether you have a ceiling application or an underfloor installation, Titus has the Green Solution for you! Many of our products are GreenSpec Listed and we have a knowledgeable and experienced staff of industry professionals ready to provide assistance when needed. The marketing collateral we have made available on the Energy Solutions site is directly related to our Green products as well. The Energy Solutions

Brochure and the Retrofit Energy Solutions Guide are two brochures created to focus on Green products. The Energy Solutions Brochure is a 4-page guide that not only shows the types of products we offer, but highlights what LEED Credits they assist in achieving. The Retrofit Energy Solutions Guide provides a more thorough look into how an older building can be retrofitted and the energy savings available if new system or components were to be installed.

Our goal in creating the Energy Solutions website is to provide you with a very informative and green-focused interactive resource for today’s demanding building needs. Sustainable design and energy conservation concepts are here to stay and this new tool will assist you in meeting those demands.

We have also completely revamped our case studies to provide a more in-depth perspective into some of our Green projects. They illustrate the overall design process from concept to completion. Our case studies also display which Titus products were selected and highlights how they solved the project’s air distribution needs. We also have flyers, green presentations, installation manuals, and application guides available on the site.

The HVAC system plays a vital role in achieving healthy buildings to work in, but the LEED Credits associated with them tend to be missed. The sections of LEED that directly relate to Titus’ air distribution products primarily fall under Energy & Atmosphere (EA) and Indoor Environmental Quality (EQ) sections of LEED. The U.S. Green Building Council’s Leadership in Energy and Environmental Design standard (LEED) has quickly become the basis for determining a building’s “Green” status.

Van Buren Township, Michigan

THE TITUS SOLUTION SmithGroup, a full-service architecture and engineering firm, had a ingenious idea for the underfloor application. George Karadis, PE, Vice-President and Director of Mechanical Engineering for SmithGroup, envisioned an integrated system for the building perimeter that did not utilize fan coil filter units, underfloor partitions or a myriad of control devices. The solution satisfies all perimeter heating, ventilating and air distribution requirements through one linear floor grille assembly. Incorporated into the continuous CT linear bar grille frame are varying sets of segmental nuanced aperture plates, blank-offs and deflector wings that are mounted into heating, cooling or return plenums. The next stage of development involves actuation of a sliding aperture plate beneath a fixed one. This will modulate the open area through which the air jets pass. Variable cooling requirements will be met while maintaining a nearly

LEED CERTIFICATION: None

constant velocity of air and plume heights. Titus engineers then turned their concept into a viable product - The TAF-L Perimeter System.

THE END RESULT By arranging the floor grille over the aperture plates, it created room air induction, thus raising the temperature of the air jets and reducing the height of the vertical plume. The Visteon project design utilizes a floor pressure of .07”w.g. which discharges 225cfm of conditioned air in a 6-7’ vertical plume at an angle of 5B. This mixes the air in the occupied zone without disturbing the stratified layer overhead. The TAF-L Perimeter System addresses the challenge of handling perimeter loads in a modular system. The CT-TAF-L linear bar diffuser, which mounts into the TAF-L’s cooling, heating or return plenum, is designed to handle the high loads of the perimeter while maintaining the engineered plume height throughout its operating range.

Energy & Atmosphere Prerequisites

Three prerequisites exist in the Energy & Atmosphere section, they are: Fundamental Building Systems Commissioning, Minimum Energy Performance, and CFC Reduction in HVAC&R Equipment.

Optimize Energy

Credit 1 is Optimize Energy Performance. The intent of this credit is to achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use. There are three methods of achieving the Optimize Energy credits. The first, and currently most common, method is based on percentage of reduction from ASHRAE Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, and range from 12% reduction (1 Point) to 48% reduction (19 Points) for new buildings. The requirement for optimizing energy performance credit is to reduce the design energy cost compared to the energy cost budget for systems regulated by ASHRAE™/IESNA Standard 90.1-2007. Per LEED, regulated energy systems include HVAC, service hot water and interior lighting. The second method of achieving this credit is to comply with the Prescriptive Compliance Path in the

A32

APPLICATION GUIDE - LEED & GREEN BUILDINGS

ASHRAE Advanced Energy Design Guide for Small Office Buildings 2004. Using this method, you can achieve 1 point. The last method of achieving the Optimize Energy credit is to comply with the Prescriptive Compliance Path in the Advanced Buildings™ Core Performance™ Guide developed by the New Buildings Institute. You can achieve 1 to 3 points using this method.

UnderFloor Air Distribution Systems

One way to achieve energy optimization credit is with an underfloor air distribution (UFAD) system. A UFAD system may have higher HVAC equipment efficiency as access floor air systems use warmer supply air (60B to 65BF) than conventional systems that use 55BF supply air. Raising the discharge temperature of many system types reduces energy consumption. UFAD systems can move a larger volume of air with overall lower pressure drops. The underfloor plenum needs 0.1 inch of water pressure or less for proper diffuser performance. This results in less fan horsepower needed for access floor systems resulting in lower energy usage. Additional energy savings and higher levels of occupant comfort for UFAD projects can be obtained by using the TAF-L linear system to provide VAV cooling and Fin Tube (hydronic or electric) heating on perimeter zones. TAF-L system is passive and eliminates the need for fan powered terminals. The TAF-L-V cooling units can also be located in variable occupancy areas such as conference rooms or waiting areas to maximize occupant comfort. The energy savings of an access floor system should be considered as part of the system to receive an Optimize Energy Performance credit.

Displacement Ventilation Systems

Displacement ventilation systems use the natural buoyancy of warm air to provide improved ventilation and comfort. Cold air from a displacement diffuser moves slowly across the floor until it reaches a heat source, such as a person or a computer, then rises. Displacement ventilation systems cannot be used for heating however, so a supplementary heating system is required.

LEED and Green Building Application Guide The system design of a displacement ventilation system is very similar to a UFAD system. Therefore it can help achieve the Optimize Energy Performance credit.

Chilled Beam Systems

Chilled beam systems are water based cooling systems. Because cooling with water is more efficient than cooling with air, these systems can save energy and help achieve the Optimize Energy Performance credit. There are two types of chilled beams, passive and active. Both types use convection of room air over a cooling or heating coil to maintain comfort. A passive chilled beam does not have a supply air inlet. Fresh air must be supplied through a separate fresh air system. Active chilled beams have a supply air inlet. In either system, the airside volume is much lower than in an all air systems. This reduces the fan size and therefore reduces the fan energy usage.

ECM Motors

ECM motors are another option that should be considered for the Optimize Energy Performance credit. The ECM motor has efficiencies of up to 70% across its entire operating range (300-1200 rpm) and 80% over 400 rpm. The ECM motor is available in all of the Titus fan-powered terminals. See the ECM Application Guide, AG-ECM, for more information.

DynaFuser Auto-Changeover Perimeter Diffuser

Most perimeter areas of commercial buildings require both heating and cooling. Typically a split overhead system uses two slot diffusers mounted end to end or one diffuser with multiple slots. In the two diffuser system, one diffuser is set for horizontal discharge and the other for vertical. With a multiple slot diffuser, half of the slots are set to discharge horizontally and half discharge vertically. Even though these methods work, they are not the optimum solution. In both the heating and cooling modes, half the supply air is being discharged in the wrong direction. During heating, half the air is discharged horizontally which causes stratification along the ceiling. In cooling, half the air is discharged vertically causing unwanted drafts along the floor.

The Titus DynaFuser was designed to solve the perimeter challenge. The DynaFuser automatically changes the air discharge pattern to the correct position for heating and cooling applications. This allows 100% of the supply air to be utilized in either application to achieve optimum comfort in the occupied zone. Lab tests have shown that the return temperature was 3.25BF lower using the DynaFuser test, compared to a split flow perimeter slot diffuser. This equates to a saving of 26.5% of energy by not directing warm supply air directly to the return. The DynaFuser not only increases the comfort level by correctly discharging supply air in both heating and cooling modes, it does so without the use of an internal or external power source which translates to energy savings for the building owner. When 100% of the supply air is utilized, the room temperature reaches the set-point faster requiring the HVAC system to run for a shorter duration of time, which saves energy. In fact, preliminary lab tests indicate energy savings to be 10-40%, which can help achieve the Optimize Energy Performance credit.

Enhanced Commissioning

Credit 3 is for beginning the commissioning process early during the design process and executing additional activities after systems performance verification is completed. The independent commissioning authority should be: xx Independent of the work of design and construction. xx

Not an employee of the design firm, though they may be contracted through them.

Not an employee of, or contracted through, a contractor or construction manager holding construction contracts.

May be a qualified employee or consultant of the Owner.

Consider air balancing the diffusers, registers, and grilles as part of the additional commissioning tasks of the building systems.

LEED and Green Building Application Guide Material & Resources Total Material Value and MEP Products

Many of the Credits in the Material & Resources section of LEED require the project to calculate the total material value of the project. Mechanical, electrical, and pluming (MEP) products as well as labor, overhead, and fees are not to be included. The reason for excluding MEP products is that typically, MEP products are not recycled or reused, which is the focus of the Material & Resources section of LEED. Including MEP products would increase the total material value of a project while not adding value to the total recycled or reused material content, and, therefore, make it more difficult to achieve the 5%, 10%, or 20% necessary to achieve some of the Material & Resource Credits.

Prerequisite

The Material & Resources section has prerequisite Storage & Collection of Recyclables.

Building Reuse

If the project is a renovation, Credit 1.1 or 1.2 Building Reuse, may be applicable. Credit 1.1 is for maintaining at least 55%, based on

Figure1 - Titus Manufacturing Locations

A34

APPLICATION GUIDE - LEED & GREEN BUILDINGS

surface area, of existing walls, floors and roof. Credit 1.2 is for maintaining 50% of existing interior nonstructural elements such as interior walls, doors, floor coverings and ceiling systems. Utilizing access floors systems can update a building for meet current technology needs without demolishing the current building structure. In situations where the architect wants to leave an ornamental ceiling open, access floor air distribution may be the perfect solution.

Recycled Contents

Credits 4 (1 to 2 points) Recycled Contents: 10% and 20%, respectively are for using post-consumer and post-industrial recycled contents materials. The intent for the recycled contents credit is to increase usage of building products incorporating recycled content materials. When determining the percentage of recycled contents used in the building project, all post-consumer recycled contents materials can be included and count toward the 10% or 20% total. However, the post-consumer recycled contents materials are valued at 50% of the total percentage used. For example, if 7% of the total building project is post-consumer recycled, then 7% is counted and 4% of the total building project is post-industrial, then 2% is counted. Using 10% recycled contents qualifies for one point,

LEED and Green Building Application Guide using 20% or more qualifies for an additional point. Two points is the maximum credit for Recycled Contents.

Indoor Environmental Quality

For recycled materials that are used as a component of another product, the value of recycled materials that are used as a component of another product is determined by weight. Divide the weight of the recycled content by the weight of the complete product and use that percentage of the dollar value of the product for the recycled content dollar value.

The Indoor Environmental Quality section has two prerequisites: Minimum IAQ Performance and Environmental Tobacco Smoke (ETS) Control. The Minimum IAQ Performance prerequisite requires the project to meet the minimum requirements of voluntary consensus standard ASHRAE 62.1-2007, Ventilation for Acceptable Indoor Air Quality, and approved Addenda using the Ventilation Rate Procedure.

Regional Materials

Additional points are given for utilizing local building materials. Depending on the project site, the project may qualify for Regional Material points, Credit 5. It qualifies the project for 1 point for using 10% regionally extracted, harvested, processed, and manufactured material. It also provides an additional point for 20% regionally extracted, harvested, processed, and manufactured material. The intent of the Regional Materials credit is to increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the regional economy and reducing the environmental impacts resulting from transportation. Products and building materials with final assembly within a 500-mile radius of the construction site meet the Regional Materials credit guideline. Titus manufactures product all over the country, so many of the terminals, diffusers, and grilles used in a project may help qualify for Regional Material points. Whenever possible consider product manufacturing plant location when selecting products to qualify for Regional Material points. Figure 1 shows locations of Titus manufacturing plants with a shaded circle indicating a 500-mile radius of each plant. The Green Building section of the Titus website has a distance calculator that calculated the distance from all of the Titus manufacturing facilities to the specified project zip code. The distance calculator can be found at http://www.titus-hvac.com/greenbuilding/plant_distance.asp.

Prerequisites

The DynaFuser can also help achieve the ASHRAE 62.1 ventilation requirement in the perimeter system. There are a couple of design issues related to perimeter heating that are discussed in the ASHRAE standards that LEED requires. If a design uses a typical split airflow pattern, with half the air going across the ceiling and half the air pointed down the glass, there are a couple of rules that must be followed. First, the throw at 150 fpm should reach to about 4 ft from the floor. This guaranties that fresh air gets into the occupied zone during heating. Second, the temperature differential from setpoint to supply cannot exceed 15BF. If these conditions are not met, then the air change effectiveness defined in ASHRAE 62.1 is reduced from 1.0 to 0.8. This means that 25% more fresh air needs to be brought in to meet the ASHRAE 62.1 requirement for IAQ. The DynaFuser solves this by putting 100% of the air where it needs to be during cooling and heating.

Increased Ventilation

Credit 2 provides one point for Increased Ventilation. This creditâ&#x20AC;&#x2122;s intent is to provide additional outdoor air ventilation to improve indoor air quality for improved occupant comfort, well-being and productivity. The credit requires the ventilation system design to Increase breathing zone outdoor air ventilation rates to all occupied spaces by at least 30% above the minimum rates required by ASHRAE Standard 62.1-2007, Ventilation for Acceptable Indoor Air Quality. Displacement ventilation systems can help achieve the increased ventilation credit. ASHRAE Standard 62.1, table 6-2, Zone Air Distribution Effectiveness, rates the air distribution effectiveness of a displacement ventilation system as 1.2. The zone air distribution effecAPPLICATION GUIDE - LEED & GREEN BUILDINGS

A35

LEED and Green Building Application Guide tiveness is a measure of how effectively the zone air distribution uses its supply air to maintain acceptable air quality in the breathing zone. A rating of 1.2 is essentially equivalent to stating that a displacement ventilation system requires 20% less fresh air than an overhead cooling system which has a rating of 1.0, or in terms of the Increased Ventilation credit, that 20% of the 30% required is achieved by default when a displacement ventilation system is utilized. This means that less actual fresh air is required to achieve this credit. For heating, the perimeter overhead heating systems must be sizes correctly to achieve a zone air distribution effectiveness of 1.0. If a split overhead system is being used, proper selection of the overhead perimeter slot diffuser throw is necessary to ensure that fresh air is provided to the occupied zone in both cooling and heating modes. The diffuser should be selected so that the isothermal (cataloged) data for the 150 fpm throw reaches the 4 ft level from the floor of the occupied space and the supply air does not exceed 15BF over the zone temperature. If the diffuser is not selected in this manner, the zone air distribution effectiveness becomes 0.8 and additional fresh air will need to be supplied to the zone. Bringing in additional outside air in the heating season will also increase energy usage due to the need to heat up the cold outside air before supplying it to the zone. The DynaFuser can solve this issue be putting the air where it needs to be in both cooling and heating seasons.

Credit 7.1 (1 point), Thermal Comfort - Design requires that the building comply with ASHRAE Standard 55-2004, for thermal comfort standards. ASHRAE Standard 55-2004, Thermal Environmental Conditions for Human Occupancy specifies the combinations of indoor space environment and personal factors that will produce thermal environmental conditions acceptable to 80% or more of the occupants within a space. The environmental factors addressed in the standard are temperature, thermal radiation, humidity, and air speed; the personal factors are those of activity and clothing. It has been shown that individual comfort is maintained when the following conditions are maintained in a space: xx Air temperature maintained between 73-77BF. xx

Relative humidity maintained between 25-60%.

Maximum air motion in the occupied.

50 fpm in cooling.

30 fpm in heating.

Floor to 6-foot level, 5-6BF maximum temperature gradient.

Controllability of Systems

The ASHRAE comfort standard states that no minimum air movement is necessary to maintain thermal comfort, provided the temperature is acceptable. To maximize energy conservation, we should attempt to maintain proper temperatures at the lowest possible air speed. The ASHRAE comfort charts, Figures 3 and 4 show the relationship between local air velocity and temperature difference in the ankle and neck regions.

The credit states that, “Individual adjustments may involve individual thermostat controls, local diffusers at floor,…” as potential strategies to achieve this credit. VAV diffusers, such as the Titus T3SQ would also qualify for this credit as well as access floor diffusers such as the TAF-R.

Air Diffusion Performance Index (ADPI) is the best way of assuring that a space will meet the ASHRAE Standard 55 requirement for 5-6BF maximum temperature gradient. ADPI is a single-number means of relating temperatures and velocities in an occupied zone to occupants’ thermal comfort. To calculate the ADPI of a space, you need to measure the temperature and velocities at points throughout the occupied space. The occupied space is defined by ASHRAE as being the area from the floor to the six foot height, one foot from the walls. The effective

Credit 6, Controllability of Systems, has two parts: 6.1 Lighting and 6.2 Thermal Comfort. The intent of Credit 6.2 is to provide individual comfort controls for 50% of the building occupants to enable adjustments to suit individual task needs and preferences.

A36

Thermal Comfort

APPLICATION GUIDE - LEED & GREEN BUILDINGS

LEED and Green Building Application Guide

Figure 4. Neck Region Comfort Chart

draft temperature is then calculated for each point. The effective draft temperature (Q) is equal to the room temperature (tx) minus the local temperature (tc) minus 0.07 times the local velocity (Vx) minus 30. Q = (tx-tc) – 0.07(Vx-30) The ADPI value is the percentage of the points where Q is between -3 and +2 F inclusive, with a room velocity of 70 fpm or less. ASHRAE guidelines state that the ADPI of greater than or equal to 80 is considered acceptable. With the TEAMS GRD selection program, you don’t need to measure points in the occupied space and calculate the effective draft temperature to calculate

ADPI, the software does it for you. The example below shows two selections, the OMNI and the PAS. By using the ADPI calculator in TEAMS, the software will change the line that normally displays velocity to display ADPI. Selecting the Performance button, you can enter a CFM, in this case 200 CFM. The CFM shows up in the data in yellow. This is especially important in VAV systems. In a VAV system, the VAV box only runs at full flow at full load, which is typically only on the hottest days of the year. Most of the time the VAV box will be at turn down, so to have a comfortable space, the diffuser ADPI must be 80 or greater throughout the airflow range of the VAV box. You can see that the OMNI maintains an acceptable ADPI at a lower CFM than the PAS. In this example, at 100 CFM the OMNI still has an acceptable ADPI of 80 while the PAS at the same 100 CFM has dropped below 80. You can also use the TEAMS selection to determine the best airflow range for given

standard and within the control of the building designer.

To achieve the LEED IEQ Credit 7.1 for Thermal Comfort Design, an engineer must show that they designed the building to meet ASHRAE Standard 55-2004. Including the TEAMS ADPI screens in the supporting documentation for the credit can help the engineer show that they designed to ASHRAE Standard 55-2004.

Each of the three energy-using systems of the building — the envelope, the heating, cooling and water heating system, and lighting system — is eligible for one third of the incentive if it meets its share of the whole-building savings goal. Explicit interim compliance procedures are provided for lighting.

Although the occupied zone’s velocity and temperature is important in all HVAC systems, UFAD systems require careful consideration as the air is introduced directly into the occupied zone. The ability of the UFAD diffuser to rapidly mix room air into the supply air at low velocities is the key to success. Slowing the supply air down 50 fpm and warming it up to 75BF as close to the diffuser face as possible provides the most occupant comfort. A typical UFAD diffuser should reach the 50 fpm and 75BF point within a 1 to 2 foot radius from the center of the diffuser. As the radius increases to reach the 50 fpm and 75BF point, the usable floor space decreases.

Green Building Codes and Programs With energy considerations growing, there is an increased interest in “green” buildings, sustainable design, and energy savings. Although the U.S. Green Building Council is not a government agency, many local governing bodies are requesting, and in some cases requiring, green design features into their new construction requirements. Some states and cities offer tax incentives for buildings that meet green building codes or become LEED certified and others will most likely offer incentives in the future.

A38

Eligible buildings include commercial buildings such as: offices, retail buildings, warehouses, etc., rental housing of four stories or more, and publicly-owned buildings. For publicly-owned buildings, there is a provision allowing the credit to pass through to the “person primarily responsible for designing the building.” New construction in an existing building is also eligible for the tax deduction, with one third of the deduction amount for new construction that affects the new energy-using system (such as lighting or heating, cooling and water heating).

Federal Green Requirements

All new GSA building projects must meet criteria for basic LEED certification. The Department of State has committed to using LEED on the construction of new embassies worldwide over the next 10 years. All of EPA’s significant new facility construction and new building acquisition projects are required to meet the U.S. Green Building Council’s LEED Silver standard.

The Energy Policy Act of 2005 (EPAct 2005), which goes into effect December 31, 2005 provides new tax incentives for energy efficiency measures.

The Air Force has developed a LEED Application Guide for Lodging projects and has conducted LEED training seminars for its design and construction personnel. The Air Force encourages the use of LEED for new or major renovations for military construction projects and has created an online design guide for sustainable development structured after LEED. The Army has adopted LEED into its Sustainable Project Rating Tool.

For commercial buildings, the EPAct 2005 offers business taxpayers a deduction of $1.80 per square foot for commercial buildings that achieve a 50% reduction in annual energy cost to the user, compared to a base building defined by the industry standard ASHRAE/IESNA 90.1-2001. Energy costs refer only to heating, cooling, lighting and water heating, since only these uses are within the scope of the ASHRAE

The Navy encourages sustainable development in its facilities requiring all applicable projects to meet the LEED Certified level, unless justifiable conditions exist that limit accomplishment of the LEED credits necessary for achieving the Certified level. Submission to the USGBC for LEED certification is not a requirement, but is recommended for high visibility and showcase projects.

Several states have adopted green building standards for publicly funded projects. Many of the states not listed below are currently considering green buildings requirements. xx California requires LEED Silver for all new state-funded buildings.

that meet LEED or other generally accepted green building standards. xx

Oregon’s 35% Business Energy Tax Credit for sustainable buildings is tied to the LEED certification level achieved. A LEED Silver rating is the minimum standard to obtain the tax credit for sustainable buildings.

In Pennsylvania, buildings for the Department of Environmental Protection and the Department of Conservation and Natural Resources are encouraged to achieve LEED Silver certification.

The State of Illinois Capital Development Board is considering requiring LEED certification of public projects.

Maine requires all new or expanding state buildings to incorporate LEED guidelines provided that standards can be met on a cost-effective basis.

Washington State is the first state to require LEED Silver Certification for all publicly funded new construction projects and major remodels over 25,000 square feet.

Maryland requires all capital projects greater than 5,000 square feet to earn LEED certification. The state also approved a green building tax credit for commercial developers. Maryland’s Green Building Council has created a green building program based on the LEED standard.

Wisconsin is using LEED on public projects and intends to seek certification.

Massachusetts is considering LEED adoption for all state projects as well as a green building tax credit program.

The state of Michigan requires that all state-funded capital projects over $1,000,000, including state agencies, universities, and community colleges, be constructed to a LEED Certified level.

Missouri is currently using LEED on public projects and intends to seek certification.

New Jersey requires all new school designs to incorporate LEED guidelines. The New Jersey Economic Schools Construction Corporation is encouraging the use of LEED, but not requiring certification of new projects built under its $12 billion public school construction program.

New York encourages, but does not require, state projects to seek LEED Certification. New York was the first state to implement a green building tax program. The credit allows builders who meet energy goals and use environmentally preferable materials to claim up to $3.75 per square foot for interior work and $7.50 per square foot for exterior work toward their state tax bill. New York State Energy Research and Development Authority (NYSERDA) offers an incentive for design teams of any New York State building that achieves a LEED rating. NYSERDA’s New Construction Program offers a 10% increase on incentives for energy efficiency measures that reduce the use of electricity. NYSERDA provides low interest loans (4% below market rate) for energy efficiency measures and building materials

Local Green Requirements Some counties and cities have adopted green building requirements. The list below shows many of the local green building requirements for North America. xx Alameda County, CA projects must be LEED Silver certified. Materials procured for construction as well as furniture, fixtures, and other interiors will be recyclable, durable, and have a low-environmental impact. xx

Arlington County, VA allows commercial projects and private developments earning LEED Silver certification to develop sites at a higher density than conventional projects. All site plan applications for commercial projects are required to include a LEED Scorecard and have a LEED Accredited Professional on the project team regardless of whether or not the project intends to seek LEED certification. All projects must contribute to a green building fund for county-wide education and outreach activities. The contribution is refunded if projects earn LEED certification.

Cook County, IL requires LEED certification of all county building projects. The ordinance also calls for projects to earn a minimum of 8 credits in the Energy & Atmosphere category to ensure best life-cycle returns.

Dane County, WI developed a Green Building Policy, which is primarily guided by the LEED rating system.

King County, WA requires all new public construction projects to seek LEED certification and encourages the application of LEED criteria to building retrofits and tenant improvements.

Overview

DESIGN FEATURES PERSONALIZED VAV SYSTEMS

Titus brings both accuracy and flexibility to the variable air volume (VAV) market with T3SQ VAV diffusers. The T3SQ combines the functions of a VAV terminal and a high performance diffuser in one. The T3SQ modulates the air volume delivered to a zone to accurately control cooling and heating conditions. The unique variable geometry design results in maximum air distribution effectiveness at any air flow, for superior comfort conditions. T3SQ adds application flexibility by being able to operate stand-alone with thermal or analog controls. In addition to a superior performance VAV unit, the T3SQ is solidly constructed with 18-gauge steel. Available in many frame styles, the T3SQ can be installed in almost any ceiling as easily as a standard diffuser. The architecturally pleasing design coordinates with any office environment. For applications that require system simplicity, proven technology and superior comfort, specify the Titus T3SQ series of VAV diffusers.

•• Variable geometry diffuser design maintains jet velocity at all flow rates, varying air flow pattern for optimal performance. •• Separate cooling and heating setpoints on thermal T3SQ. •• Supply air temperature provides automatic cooling/ heating changeover on configurations -4 and -2. •• T3SQ-2, digital, can control up to 14 drones. •• Optional electric inlet heater for applications requiring supplemental heat (T3SQ-2 only). •• Provides accurate, personal environmental temperature control to improve productivity in the office environment. •• Superior air distribution performance provides greater entrainment, higher Air Diffusion Performance Index (ADPI) and better ventilation effectiveness for Indoor Air Quality (IAQ). •• Lower cost per zone of control than typical VAV terminal with separate diffusers. •• Renovate existing offices or add zones in problem areas to solve individual comfort problems.

Thermal VAV Diffuser

Supply air temperature sensor provides autochangeover from heating to cooling operation.

DESIGN FEATURES

Easy to turn minimum airflow adjustment ring.

Single piece backpan with multiple border types available to complement various ceiling designs.

Thermal actuator assembly lifts and lowers the control disc producing uniform air pattern in all positions.

Installation and relocation are made easy. •• Constant volume systems can easily become multi-zoned VAV systems, for “big building comfort” on a small building budget. •• Easy and inexpensive to relocate zones, ideal for use where office space may be reconfigured periodically. •• Easy to install and operate. •• Unique center induction on thermal T3SQ-4 ensures accurate readings even at low flows.

Easy to turn heating and cooling setpoint adjustment rings (heating setpoint adjuster only available on heating / cooling units).

Venturi tube and center induction design provide fast and accurate response to changes in zone temperature. A tight horizontal air pattern is achieved by the intelligent curvature design of the backpan.

Face plaque’s curved edge reduces diffuser sound and creates a smooth appearance.

VAV Diffusers

Application Guidelines The Titus T3SQ system is ideal for use with a constant volume system. The T3SQ gives all the advantages of a VAV system at low pressure conditions and reduced installation cost. The T3SQ is a low pressure, pressure dependent, variable air volume (VAV) system. The T3SQ is designed to operate around 0.15â&#x20AC;?- 0.20â&#x20AC;? inlet pressure. This system provides zoned comfort, which is not always possible with a typical constant volume system. 1. It is recommended that a static pressure controller such as the Titus ZECV/ZQCV be installed into a constant volume system when more than 30 percent of the system airflow is put under the control of T3SQ

diffusers. This minimizes the possibility of delivering excess air when a portion of the Zcoms are operating at part load conditions. 2. When an entire constant volume system uses T3SQ zone control, a ZECV/ZQCV box should be implemented. The Titus ZECV/ZQCV pressure control terminal should be sized for 80 percent of the total supply flow, less the airflow of the smallest zone. 3. Care must be taken when sizing and installing a ZECV/ ZQCV. The unit should be installed as far downstream from the fan as is practical to maximize supply and return air mixing. This reduces the risk of the unit cycling on high or low.

Digital VAV Diffuser

MASTER / DRONE T3SQ-2 diffusers are all shipped as drone units. Determination of master units is made through plug and play cable connections to the thermostat. The units connected to the thermostat are the master units. All units daisy chained from the master are drones. Drone diffusers must be connected to a master diffuser in order to operate. One power module is required for every 15 diffusers with or without optional electric reheat. Power module requires 120, 208, 240, 277 VAC line voltage input. The 4-pin mini-fit cables provide 24VAC power and communication between diffusers. This cable should be used between the power module and the first diffuser and also to connect a master unit to a drone unit. Blue RJ-45 8-pin cables provide 24VAC power and control signal between diffusers. RJ-45 cables should be used Master/Drone Wiring

between diffuser and master controller/thermostat and between master and drone units. The Master Communications Module is a central data collection and distribution point for up to 60 VAV field diffusers. The device features four diffuser channel inputs, which can accommodate up to 15 diffusers each. This allows the users to interface with 60 diffusers per communication module through a building management system. The interface software also has a server application which allows all communication modules on site to be accessed through the building management system from the i.p. address of each module. Master communication modules are available in the following communication protocols: • Standard Master Communication module (Stand-Alone) • Master Communications module with Lonworks gateway • Master Communications module with BACnet gateway RJ12 4-pin mini fit cable drone unit

P.S.

One master unit can control up to 14 drone units.

T3SQ-4

Configurations: T3SQ-4

•• The T3SQ-4 is a thermal variable volume diffuser. The diffuser maintains space temperature by varying the volume of air delivered to the space. The amount of air delivered will depend on the Supply Air Temperature (SAT) (-4 only), the room temperature setpoint, and the room temperature. •• Available in heating/cooling (-4) configuration. •• As the volume of air is decreased by the control disc, the velocity of air is increased, thereby maintaining the longest throw and best entrainment. Insuring superior air distribution at all damper positions. •• The curvature of the backpan works with the formed edges of the face panel to deliver a tight horizontal air pattern, without excessive noise or pressure drop over the full range of operation.

•• The T3SQ-4 uses a center induction plug to accurately measure the room temperature. This eliminates the need for a wall mounted thermostat or sensor and provides the most accurate way of measuring the room air temperature. •• Adjustment of the room temperature setpoint is achieved by rotating the blue (cooling) only adjustment ring. •• Adjustment of the green tab offset creates a temperature deadband for heating and cooling setpoints. •• Adjustment of minimum airflow is achieved by rotating the grey minimum airflow adjustment ring. •• Standard finish is #26 White. •• The face panel and backpan are constructed from 18-gauge steel. The formed outer edge also assures a straight and level surface.

VAV Diffusers

PERFORMANCE DATA

The performance of the T3SQ diffuser is related to supply static pressure and size. If the supply static pressure is held at a constant value and the VAV diffuser damper is throttled to a closed position, the airflow pattern is changed from a square pattern to a star pattern. The isovel in the adjacent illustration demonstrates this pattern change. With the

reduction of cfm, throw does not decrease as in standard diffusers. As the damper closes the discharge velocity is slightly increased, minimizing throw reduction. With a fixed inlet pressure, the sound values have very small changes of intensity as the damper is modulated.

The device features four diffuser channel inputs, which can accommodate up to 15 diffusers each. Communication on these channels is by means of a Lin bus interface to four field Power Supply units connected by dedicated communication cables. This centralized data is monitored on a PC running the MLM software Application via an Ethernet TCP/IP interface. The MLM software Application is designed as a commissioning

SUGGESTED SPECIFICATIONS

In addition to the collection and distribution between field diffusers and the MLM Application, the unit also features an on-board web server. This web server can be accessed by a standard browser tool and is used to setup IP addresses, Device identification data as well as communications parameters. In general the web server is used on initial installation to bind to the IP network and to uniquely identify the product, normally by physical location. A serial USB port provides limited diagnostic capability. In general it is used in production to set MAC, IP and port addresses. It can be used to verify and set port and IP addresses. A LON compatible gateway is achieved by adding a plugin hardware module to the MCU. This hardware module contains a subset of the ANSI/CEA-709.1-B (EN14908.1) protocol stack and interface via a TP/FT-10 (Free topology) transceiver network to the device bus. The functional block implementation is indicated in LHA DOC BQ0254-A. Up to 20 of these functional blocks can be selected for a client interface to 20 master control zones. Again the user has the option to use the MLM Application for diffuser setup and diagnostics and the Lon client for general control supervision.

APPLICATION GUIDE

General This document provides application and design highlights for underfloor air distribution (UFAD) systems. Additional information may be found at the Titus website. www.titus-hvac.com

Introduction The interest in underfloor air distribution (UFAD) has increased significantly in the U.S. market over the last fifteen years. There is currently several million square feet of access floor air distribution systems being designed across the country. In 1997 Titus introduced the TAF-R diffuser and the TAF-G grommet, which were installed in the Owens Corning World Headquarters. Since then, Titus, ASHRAE, and the engineering community have continued to learn about UFAD systems. In the time that Titus has participated in UFAD designs in the US, we have continued to introduce new products to meet the needs of this unique application.

APPLICATION GUIDE

Overview

ASHRAE Applications Handbook (2011) describes Underfloor Air Distribution Systems (UFAD) as Partially Mixed Air Distribution. Where traditional ceiling or high sidewall supply outlets condition the space by creating a thermal mixing zone from the floor (ankle level) to near the ceiling, Underfloor systems create a mixed zone from the floor to the top of the occupied zone (6’ above the floor), and let the upper zone be fully stratified. The height of the mixed zone is controlled by the height of the air jet to a velocity of 50 fpm. The ideal throw height of the jet is to 4’ – 5’ above the floor. Contaminates above the mixed zone will rise through the stratified zone and be carried out of the room through the return. Where a fully mixed system uses the area within one foot of the interior walls as a mixing zone, a floor outlet uses the area around the outlet where mixed air velocities are greater than 50 fpm. Floor outlets used in the interior area (more than 12’-15’ from a perimeter wall) are typically round producing a swirl air pattern. The mixing zone, typically known as the “clear” zone is defined by the manufacturer. It is recommended that occupants not be permanently stationed in the clear zone. UFAD systems utilize the space under an access

UnderFloor Air Distribution floor as an air plenum. Properly designed UFAD systems take advantage of thermal stratification. ASHRAE recommends that, for comfort, the temperature in the occupied zone be between 73B and 77BF, relative humidity be between less than 60%, and the maximum velocity in occupied zone be 50 fpm in cooling or 30 fpm in heating. The key to successful access floor systems is the ability of the access floor diffuser to rapidly mix room air into the supply air at low velocities. Because supply air is introduced directly into the occupied zone, it is important that the supply air reach the ASHRAE recommended temperature and velocity, mixing of the supply air into the space should happen rapidly. The typical application for a UFAD system is the open plan office. Floor space is at a premium in a cubicle so a smaller clear area around the diffuser will allow more usable space in the cubicle. The UFAD diffuser manufacturer defines the required clear area that their diffuser needs to achieve the ASHRAE recommended temperature and velocity. Originally UFAD systems were for computer rooms. The design intent was to cool computer equipment and not to provide comfort. The computer room design concept typically provides too cold of a space for comfort. There has been a growth of UFAD systems used in offices and headquarters in U.S. It is estimated that 10% of U.S. construction will utilize access floors within few years. While the early interest in UFAD systems was primarily due to companies’ need to easily rearrange office layouts, information and communications based offices, the economics of ownership, and green building programs such as LEED have largely influenced the growth of UFAD in recent years.

DESIGN BASICS PLENUM DESIGN The raised floor office can be supplied with conditioned air from below the floor in two ways – pressurized plenum or neutral plenum.

PRESSURIZED PLENUMS The pressurized plenum (the area between the slab and the raised floor) is essentially a large duct maintained at a constant pressure differential to the room above; typically between 0.05 and 0.10 in. pressure (w.g.). This pressure is maintained through the supply of conditioned air from a number of supply duct terminations. The spacing and location of these ducts are dependent on the air supply requirement and the plenum depth, with shallow plenums and / or high air quantities requiring more air supply duct outlets under the floor. UFAD diffusers are specially designed grilles with a user adjustable damper to regulate flow.

NEUTRAL PLENUMS With the neutral plenum design, the same layout as the pressurized plenum may be used, but the pressure difference between the plenum and the room is kept as close as possible to zero. Floor diffusers either contain integral fans, are ducted from a central source, or both. In many cases, these closely resemble conventional ceiling supply systems.

This design is rarely used, but may be effective in tenant buildings where the utilities will be paid by the tenant.

PLENUM DETAILS Plenum heights typically range from 14” to 18”, occasionally going as low as 12” or as high as 24”. The plenum height is usually determined by the height requirements of other equipment that will be located under the floor. The number of inlets required to supply the plenum with sufficient air to run the diffusers is dependent upon the plenum size and the number of diffusers, which in turn is determined by the load of the space. As a general rule, the longest distance from the supply air outlet in the plenum and the farthest diffuser should not exceed 35 feet. Distances longer then this are subject to thermal losses created by thermal conductivity of the return air from the floor below through the slab making the discharge temperature of the diffuser be too high. Duct runs in the plenum space known as air highways can be used to transport conditioned air from the main duct to the zone. If zone control is desired from the underfloor plenum, the plenum can be partitioned into separate zones. The zones in the underfloor plenum should correspond to building zones having similar load requirements. However, it is not necessary to partition the underfloor plenum into zones and doing so can make future office layout changes more difficult. If an office layout must be changed, the partitioned

APPLICATION GUIDE

The advantages of pressurized plenums include low first cost and easily changed layouts. This is the most commonly used plenum design.

Advantages include the possibility of multiple small zones (as with multiple tenants) and insensitivity to construction details. Disadvantages include higher first costs due to ducting and/or fan connections under the floor, lower flexibility as the grilles are individually ducted, and potentially higher noise levels.

APPLICATION GUIDE

plenum will need to be changed to match the new layout. Because of the special heating and cooling requirements of the perimeter of the building, it may be necessary to create a perimeter zone in the underfloor plenum to run a separate perimeter system. Typically only the perimeter is zoned from the core. The perimeter will be discussed in more detail next.

PLENUM LEAKAGE Sealing the underfloor plenum is critical to optimizing the operation of a UFAD system. Air leaking through the floor tiles into the occupied zone is of minimal concern because it is leaking into the occupied space. Air leaking into the space between the walls, however, is wasted energy. All knockouts and holes in the drywall below the raised floor must be sealed during construction.

More important is eliminating the leakage that occurs from the plenum through apertures into the vertical walls. Care should be taken to inspect and seal all openings into the walls where electrical, plumbing, or other items may pass from the plenum into the wall. Air leakage through these passages will result in loss of conditioned air that will never pass through the occupied zone. Inspecting these areas during the construction process when they are accessible can eliminate costly repairs during commissioning.

INTERIOR (CORE) SPACES

Note: Number of TAF-R(-FR) diffusers required depends on the airflow of the LHK

Open plan interior spaces are typically conditioned by placing a round swirl outlet at or near the entrance open to the cubicle or individuals work area. This will allow the cool jet to condition the adjacent space. Individually adjustable outlet dampers allow the occupant to control the comfort in their work zone. Larger common areas can be controlled with a single thermostat operating motorized dampers on multiple outlets.

While leakage through the floor tile seams into the occupied space is less critical it should not be ignored. Floor leakage can be minimized by applying a gasket between the floor tile and the support stringer. Securing the tile to the structure with bolts will help create a tight seal. Additional floor sealing can be achieved by lapping the floor carpet tile over the tile seams.

The perimeter is typically the most difficult area of an underfloor system to design. The perimeter is often handling much larger loads and requires the most equipment. In the past, the best way to handle the perimeter was to use fan powered terminals with reheat ducted to linear bar grilles. There are a couple challenges with this design concept. The throw of a linear bar grille ducted to the discharge of a fan powered terminal is very long, possibly as long as 15-20 feet. Designing long throws at the perimeter contradicts the

UnderFloor Air Distribution

APPLICATION GUIDE

The TAF-L perimeter system provides this ideal air pattern. The TAF-L system consists of a modular cooling plenum, the TAF-L-V, and heating plenum, the TAF-L-W, designed to be integrated with the CT-TAF-L multi-deflection linear bar diffuser.

Additional challenges on the perimeter may be caused by the radiation effect of the sun shining through the glass and warming the first four to six feet of the plenum and slab beneath the floor. Thermal conduction through the outer wall into the plenum may affect the conditioned plenum air in the perimeter area as well. Applying a spray on thermal coating or other insulation material to the wall and floor of the plenum perimeter can prevent infiltration and minimize these thermal losses. Materials that harbor mold or bacteria growth should be avoided. Although the concept of UFAD systems is to be modular, the function of handling perimeter loads is not modular. Those loads come with the building envelope, which is always a line of some sort. The TAF-L Perimeter System was designed to address all of these considerations.

PERIMETER COOLING The perimeter cooling system should combine induction, buoyancy and displacement ventilation models, handles high thermal loads such as 225 CFM per 4â&#x20AC;&#x2122; length at 0.07â&#x20AC;? wg, engage the occupied zone, but not the stratified ceiling layer. This avoids occupant complaints from air rolling back, dumping into interior space and saves energy by not mixing the warm ceiling air into the occupied zone. Field Installation

PERIMETER HEATING Perimeter heating cannot be accomplished with the same system as the interior load cooling system. Ideally, since ASHRAE 90.1 states that you should not simultaneously cool and heat, the perimeter heating system should be completely independent of the cooling system. Separate ducting of hot or reheated air, hydronic systems, or perimeter fan powered systems are often used to condition the skin load on the building. The TAF-L-W, self contained fin tube perimeter heating plenum utilizes room air to heat the perimeter instead of supply air. The TAF-L-W heating plenum also uses the CT-TAF-L to create a continuous linear look from the occupied space. The TAF-L-W works by allowing the denser cold air, which create convection currents, to flow down a window or exterior wall into the TAF-L-W plenum while also inducing warmer room air into the plenum. A finned tube heater in the plenum reheats this mixed air and room air, returning the heated air to the window or exterior wall through natural convection.

The TAF-L system provides a continuous look around the perimeter. The TAF-L-V cooling plenum used with the CTTAF-L has an engineered throw pattern that never breaks through the stratification layer created by the UFAD diffusers in the core. The dual aperture plate design allows the TAF-L-V / CT-TAF-L assembly to maintain this engineered throw pattern while modulating the airflow volume.

concept of stratification in a UFAD system. Not only does the long throw from the grille mix the air above the stratified layer into the occupied zone, wasting energy, but it also may roll up the glass and across the ceiling, where it drop into the occupied zone causing discomfort for the occupants.

S The TAF-L-E uses the same concept shown above to heat the perimeter with a fin tube electric powered SCR heater. The TAF-L-E is an ETL listed self-contained 4 ft. long sheet metal plenum which attaches to the CT-TAF-L.

APPLICATION GUIDE

The TAF-L perimeter system is modular and allows the designer to use the right number of cooling or heating units required to match the space load requirements. Typically the TAF-L-V, cooling plenums, and TAF-L-(W)(E), heating plenums are alternated as needed throughout the perimeter.

S12

The TAF-L system allows you to remove the fan powered terminals, and their associated energy and maintenance costs, from the UFAD system. However, in the event where the system cannot achieve consistent plenum pressure, a fan powered terminal may be necessary. The PFC was designed to be used as a booster unit for perimeter applications. The PFC fan powered terminal unit is designed to be installed between the pedestals in an underfloor system and installed in a floor 12” to 18” in height. The PFC is usually ducted to linear bar diffusers, such as the CT, or diffuser and plenum units, such as the TAF-D. The airflow of the diffusers is directed at the glass like a typical ceiling system.

When fan powered terminals are used with an under floor system, they are typically equipped with ultra-high efficiency ECM motors. ECM motors consume less energy and can be controlled by the unit DDC controller to adjust the fan speed to the required space load conditions. Modulating the fan speed to vary the amount of air supplied to the zone is the most common control sequence used for the PFC. The PFC controller will determine the speed of the fan based on zone temperature. For example, the fan would run 100% when the zone is 75BF and modulated down to 30% as the zone approaches 70BF.

CONFERENCE ROOMS & OTHER AREAS OF VARYING LOAD Much like the perimeter, conference rooms must be handled separately to adjust for the varying load conditions. The LHK fan powered terminal was designed for this application. Like the PFC, the LHK fits within the modular pedestal systems of the raised floor and is available in various heights to fit under 12” through 18” raised floors. With the exception of its unique dimensions, the LHK is like any other series fan powered terminal. The LHK has a supply inlet with a damper modulated by a controller and actuator. The LHK has an induced air inlet which pulls air from the underfloor plenum or from

the room depending on how the LHK is applied. The LHK supply inlet would be open to the plenum with the induced air inlet ducted to the room as the return. The discharge would then be flex ducted to TAF-R’s in the room. Again to eliminate the fan powered terminal, the TAF-L system can be used to provide comfort conditioning to varying load areas. The CT-TAF-L can be installed in the floor along the wall to provide a clean look. TAFL-V units can be attached to the CT-TAF-L as required to handle the maximum space load. The space thermostat will operate the unit dampers in response to space load conditions. Unused sections of the CTTAF-L should be blanked off beneath the floor. Large space common areas such as break-rooms can be controlled using multiple TAF-R units with electric actuators operated by a common room thermostat.

temperature at the diffuser and you gain the cost benefits of the warmer supply air temperature.

HUMIDITY ISSUES A potential problem with the higher supply temperatures used in underfloor supply systems is the higher potential moisture content of the warmer supply air used in these systems.

The supply system must reduce relative humidity to less than 60% to meet IAQ concerns, and this requires dew points less than 65BF. This implies either reheat or blending of air to achieve a 65BF supply, 55BF dew point condition. System designs utilizing condenser water reheat; runaround coils, face & bypass, and other strategies can be employed to solve these potential design problems. Other possible solutions include the use of a separate system to dry outside air or the use of desiccant dehumidification.

If the system must use 55BF supply air for humidity reasons, some of the return air can be re-circulated from the ceiling to the underfloor plenum to raise the temperature of the air to 63BF to 68BF. Another option is to take the return air back to the air handling unit where it can be filtered and dehumidified before re-entering the underfloor plenum. With this option, you can more accurately control the air

Climate and building operation are important considerations when designing a UFAD system. In humid climates, it may be necessary to operate the HVAC system 24 hours a day to maintain acceptable humidity levels in the building.

VENTILATION EFFECTIVENESS ASHRAE Standard 62.1 defines the volume of ventilation air required for a given building space. Table 6-2 shows the adjustment factors to be applied relative to the type of system being employed. For UFAD cooling the factor is 1.0 which is the same as fully mixed overhead cooling and lower than the 1.2 factor applied to Displacement Ventilation applications. ASHRAE research project RP-1373 was funded to compare ventilation effectiveness between UFAD and Displacement Ventilation outlets for several common space applications. The results of the research

APPLICATION GUIDE

Due to the upward air flow, returns should be located at the ceiling or on a high side wall at least 8’ above the floor. This allows the heat from ceiling lights to be returned before it is able to mix with the conditioned air in the occupied zone. There will also be a small amount of “free cooling” due to the natural buoyancy of hot air.

indicated that when the vertical jet from an UFAD outlet reached a terminal velocity of 50 fpm lower than 5 ft. above the floor, the ventilation effectiveness is equal to DV. When the jet projects to a height higher than 5 ft., the ventilation effectiveness is equal to fully mixed cooling. The results of this data will be published in a future Addenda to Standard 62.1. this change may impact the volume of ventilation air required to satisfy LEED requirements when using UFAD.

SIZING JOBS The optimum design point for the TAF-R is 80 100 CFM when a 10BF room / supply differential is used. At this point, the noise is negligible and the pressure required is less than 0.10”. Throw will be less than 5 ft., preserving the desired ceiling stratification layer. Our testing shows that there is 100% mixing in the occupied zone under these conditions. 1.0 W/sq.ft. (computers and printers) +1.2 W/sq.ft. (occupants) =2.2 W/sq.ft. (room load) The stratification in this installation results in a supply - exhaust DT similar to the typical 18BF to 20BF DT common in most conventional systems. For example, with 64BF supply air in a 74BF room, the room exhaust, at the ceiling, will probably be about 82BF, for an 18BF DT. This means that one diffuser can handle:

APPLICATION GUIDE

18BF DT x 100 CFM x 1.08 = 1944 BTUH or 1944 BTUH ÷ 3.41 = 570 watts of internal load. Lights are typically 0.75 W/sq.ft, but with ceiling stratification are probably not a part of the room load (but are seen by the air handler). If computers and printers supply about 1W/sq.ft. load and occupants add about 1.2 W/sq.ft, this translates to: This corresponds to one TAF-R every: 570 Watts of internal heat ÷ 2.2 W/sq.ft. room load = 260 sq.ft. floor space sensed interior zone load.

S14

As a general rule, one TAF-R should be provided for each occupant.

UnderFloor Air Distribution SYSTEM ECONOMICS The main economic considerations for a UFAD system are reduced first costs & installation costs, higher HVAC equipment efficiency, lower horsepower fans, better heat and pollutant removal, quick to install and easy to rearrange office layouts, and lower life-cycle building costs.

FIRST COSTS & INSTALLATION COSTS UFAD systems can be designed with plenum returns using the same floor to floor height as conventional systems by shifting the occupied zone up into where the ceiling plenum would normally be. The cost of the raised floor, typically $5-7 per sq.ft., is offset by the fact that less ductwork is required. The installation costs are usually lower because the HVAC and data / power work is done at floor level. In a conventional system, ductwork must go to every diffuser. UFAD systems use a pressurized plenum to supply each diffuser, so less ductwork is required. In a UFAD system, the only ducting in the underfloor plenum is the ductwork required to supply the diffusers that are more than 50-65 feet away from the dampers or the separation for the perimeter. A 1996 study in Building Design & Construction magazine showed a $2.13/sq.ft. first cost savings using UFAD systems.

HIGHER HVAC EQUIPMENT EFFICIENCY In an UFAD system, supply air enters directly into the occupied zone at the floor level. In a conventional system, the supply air temperature is usually 55BF because it must mix with the warm air at the ceiling before it enters the occupied zone. UFAD systems typically use 63-68BF supply air temperatures. This warmer supply air can reduce energy consumption of the HVAC equipment. Some DX equipment cannot supply air at this high temperature, so this must be considered when selecting the HVAC equipment.

LOWER HORSEPOWER FANS UFAD systems move a larger volume of air with overall lower pressure drops. The diffusers used in UFAD systems operate with less than 0.1” wg, so lower horsepower fan can be used, reducing energy costs.

Core

To maximize flexibility of furniture location during initial installation and re-location during churn, it is recommended that the TAFR diffuser be located at an off center location in the floor tile. This will allow the tile to be installed in the floor stringer with four choices of diffuser location but merely turning the tile. Typical churn in an office is 33%, meaning that everyone moves every three years. Diffusers are rearranged by moving entire floor panel to a new location. This reduces the time and labor costs of relocation and renovation in an office.

LOWER LIFE CYCLE COSTS Several factors of the UFAD system contribute to potential life cycle savings. The building should have an energy savings from the use of lower horsepower fans. The owner should see reduced costs for office layout changes.

location until office furniture layout is finalized.

Conventional System

By ventilating the underfloor plenum with cool air at night, the structure can be cooled to the point where the load during the early part of the day is significantly lowered. A number of strategies can be employed to take advantage of the potential for stored “cool”, resulting in lowered energy use and off-peak energy use. However, there is a potential for overcooling the occupied space during the night requiring addition morning warm up, costing energy.

POINTS

ENERGY & ATMOSPHERE

Heat from overhead ceiling lights is removed before it enters the occupied zone and lateral mixing in the occupied zone is reduced. A Lawrence Berkeley National Laboratory field study found that pollutant removal efficiency for carbon dioxide was 13% higher than expected in a space with well-mixed air, suggesting a 13% reduction in exposures to occupant generated pollutants.

There are also costs savings associated with increased thermal comfort for occupants. Because the diffusers are occupant adjustable, the facility staff should see fewer complaints about thermal comfort. Increased employee satisfaction potentially results in increased productivity. Labor costs are typically 10 times the cost of property. A 1% productivity improvement is the equivalent of 22 hours, or almost three days, of gained productivity. For a company with 115 employees earning $35,000 a year, 30 employees earning $60,000 a year, and 5 employees earning $80,000 a year, a 1% improvement would worth be almost $70,000. This is a substantial payback for a building owner.

APPLICATION GUIDE

One way to achieve energy optimization credit is with an underfloor system. An underfloor system may have higher HVAC equipment efficiency as access floor air systems use warmer supply air (63B to 68BF) than conventional systems that use 55BF supply air. Raising the discharge temperature of many system types reduces energy consumption. Underfloor systems can move a larger volume of air with overall lower pressure drops. The underfloor plenum needs less than 0.1” wg of water pressure or less for proper diffuser performance. This results in less fan horsepower needed for underfloor systems resulting in lower energy usage.

UFAD AND LEED

The energy savings of an underfloor system should be considered as part of the system to receive an Optimize Energy Performance credit.

The United States Green Building Council (USGBC) developed the Leadership in Energy & Environmental Design (LEED™) Green Building Rating System™. The LEED council is a voluntary, consensus-based national standard board for developing high-performance, sustainable buildings. USGBC members represent all segments of the building industry and update the program continuously.

ECM motors are another option that should be considered for the Optimize Energy Performance credit. The ECM motor has efficiencies of up to 70% across its entire operating range (300-1200 rpm) and 80% over 400 rpm. The ECM motor is available in the Titus LHK and PFC UFAD fan-powered terminals. See the ECM Application Guide, AG-ECM, for more information.

The growing interest in green buildings and LEED certification has increased the interest in UFAD systems. The table below shows the LEED credits that could be achieved with UFAD systems.

Credit 1 is Optimize Energy Performance. The intent of this credit is to achieve increasing levels of energy performance above the prerequisite standard to reduce environmental impacts associated with excessive energy use. Credits are based on percentage of reduction and range from 10.5% reduction (1 Point) to 42% reduction (10 Points) for new buildings. The requirement for optimizing energy performance credit is to reduce the design energy cost compared to the energy cost budget for systems regulated by ASHRAE™/IESNA Standard 90.12010. Per LEED, regulated energy systems include HVAC, service hot water and interior lighting. All LEED projects registering after June 26, 2007 are required to achieve at least two (2) Optimize Energy Performance points

If the project is a renovation, Credit 1.1, 1.2, or 1.3, Building Reuse, may be applicable. Credit 1.1 is for maintaining at least 75%, based on surface area, of existing building structure and envelope. Credit 1.2 is for maintaining an additional 20%. Credit 1.3 is for maintaining 50% of existing interior non-structural elements such as interior walls, doors, floor coverings and ceiling systems. Each credit qualifies for one point, meeting the criteria for all three credits nets a maximum of three points for the Material & Resources section. Utilizing access floors systems can update a building for meet current technology needs without demolishing the current building structure. In situations where the architect wants to leave an ornamental ceiling open, access floor air distribution may be the perfect solution.

CONTROLLABILITY OF SYSTEMS Credit 6, Controllability of Systems, has two parts: 6.1 Lighting and 6.2 Thermal Comfort. The intent of Credit 6.2 is to provide individual comfort controls for

APPLICATION GUIDE

UnderFloor Air Distribution

THERMAL COMFORT Credit 7.0, Thermal Comfort - Design requires that the building comply with ASHRAE Standard 55-2004, for thermal comfort standards. ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy specifies the combinations of indoor space environment and personal factors that will produce thermal environmental conditions acceptable to 80% or more of the occupants within a space. The environmental factors addressed in the standard are temperature, thermal radiation, humidity, and air speed; the personal factors are those of activity and clothing.

50% of the building occupants to enable adjustments to suit individual task needs and preferences.

It has been shown that individual comfort is maintained when the following conditions are maintained in a space: • • • • • •

Air temperature maintained between 73-77BF. Relative humidity maintained between < 60%. Maximum air motion in the occupied zone. 50 fpm in cooling . 30 fpm in heating. Ankle to neck level, 5.4BF maximum temperature gradient. Figure 4. Neck Region Comfort Chart

Air Diffusion Performance Index (ADPI) is the best way of assuring that a space will meet the ASHRAE Standard 55 requirement for 5.4BF maximum temperature gradient. ADPI is a single-number means of relating temperatures and velocities in an occupied zone to occupants’ thermal comfort. To calculate the ADPI of a space, you need to measure the temperature and velocities at points throughout the occupied space. The occupied space is defined by ASHRAE as being the area from the floor to the six foot height, one foot from the walls (or in the case of UFAD diffusers, outside of the clear zone of the diffuser). The effective draft temperature is then calculated for each point.

The effective draft temperature (Θ) is equal to the room temperature (tx) minus the local temperature (tc) minus 0.07 times the local velocity (Vx) minus 30. Θ = (tx-tc) – 0.07(Vx-30) The ADPI value is the percentage of the points where Θ is between -3 and +2 F inclusive, with a room velocity of 70 fpm or less. ASHRAE guidelines state that the ADPI of greater than or equal to 80 is considered acceptable. There is currently no method to calculate the ADPI for a UFAD system outside of conducting field measurements per ANSI/ASHRAE Standard 113-2009, Appendix B, Method of Testing for Room Air Diffusion.

Overview

The Displacement Ventilation system is similar to an UnderFloor Air Distribution (UFAD) system in that is uses warmer supply air and lower pressures then a conventional overhead system. As a result, displacement ventilation systems have many of the same benefits of UFAD systems, such as longer economizer periods, potential energy savings from the warmer supply air and lower horsepower fans, and quiet operation. Although many parts of North America need to cool the supply air below 65BF for humidity reasons, all areas should benefit from the increased economizer time. An additional benefit to Displacement Ventilation systems is that ASHRAE Standard 62.1-2007 Ventilation for Acceptable Indoor Air Quality gives Displacement Ventilation systems a Ventilation Effectiveness Factor of 1.2. Ventilation Effectiveness is a measure of how effectively the zone air distribution uses its supply air to maintain acceptable air quality in the breathing zone. A Ventilation Effectiveness of 1.2 means that a lower volume of fresh air can be used to meet ASHRAE 62.1 requirements. This makes displacement ventilation systems an effective way to achieve the LEED Increased Ventilation credit.

One of the challenges to displacement ventilation is that the diffusers are placed in the occupied zone, typically along the wall. Because displacement diffusers supply air directly into the room, placement of occupants is critical to achieving a comfortable space. The ASHRAE Guideline recommends that the air velocity in the occupied space not exceed 50 fpm. For a displacement diffuser, the zone where the velocity exceeds 50 fpm is called the adjacent zone or near zone. Occupants need to be placed outside of the adjacent zone for comfort. A typical displacement diffuser can maintain comfort in a space that is 5-6 times the length of the adjacent zone. Titus has a full line of displacement ventilation diffusers to accommodate any application. One unique and specifiable feature of Titus displacement diffusers is the variable air pattern controllers located behind the perforated face. The pattern controllers can be adjusted to change the size and direction of the supply air isovel and adjacent zone area. Engineers may not always know the final room layout or furniture location during the design phase. Titus displacement diffusers provide the perfect solution by offering adjustability without the need to move or change the location of the diffuser. This ability to shape and customize the airflow pattern and adjacent zone to match requirements in the occupied space ensures the highest level of thermal comfort for building occupants.

Displacement Ventilation systems use low velocity cold air to displace warm room air. They are defined by ASHRAE as fully stratified systems. Supply air is introduced low in the occupied space and travels along the floor until it reaches a heat source, such as a person or computer. Natural convection flows cause the supply air to rise around the heat source.

Displacement Ventilation

Displacement Ventilation Design & Application Guide Buildings come in all shapes and sizes and are designed for any number of purposes. In order to create healthy and productive environments, air distribution systems must be selected that best meet the goals of designers. There are a wide range of choices available, but often one system can be identified as the best solution in terms of cost, comfort and energy. The purpose of this guide is to explain how displacement ventilation works, describe recommended applications and provide engineering guidance to the system designer.

INTRODUCTION TO DISPLACEMENT VENTILATION

In order to understand the advantages and limitations of displacement ventilation, it’s important to understand the differences between conventional mixed air distribution and fully-stratified air distribution. In mixed air distribution, hot or cold supply air is delivered at relatively high velocity from ceiling-mounted diffusers. When ceiling diffusers are properly selected and positioned, this high velocity air doesn’t result in occupant discomfort because it is delivered outside the occupied zone. The purpose of the high velocity supply is to create low velocity room air motion through entrainment. Ideally, this air motion will thoroughly mix the supply air with the room air resulting in uniform temperature and contaminant levels throughout the occupied zone. Internal heat loads and contaminants are eventually picked up and carried away by the return air.

Figure 2. Fully-Stratified System The main differences between these systems are: Mixed air distribution • Suitable for both heating and cooling with a supply temperature range of 38 to 90°F. • Air is supplied to the unoccupied zone at relatively high velocity. • Minimizes temperature variations throughout the space. • Creates uniform contaminant concentration throughout the zone. Fully-stratified air distribution • Suitable for cooling only with a supply temperature range of 62 to 70°F. • Air is supplied directly to the occupied zone at low velocity. • Takes advantage of natural air buoyancy to divide the zone into two regions. • Heat and pollutants rise into the upper unoccupied zone. • Contaminant concentration is greatly reduced in the lower occupied zone.

APPLICATION GUIDE

AIR CHANGE EFFECTIVENESS

ASHRAE Standard 62.1-2010 ‘Ventilation for Acceptable Indoor Air Quality’ assigns a zone air distribution effectiveness value (Ez ) of 1.0 for conventional mixed air systems and 1.2 for fully-stratified systems (Table 6-2). This means that fully-stratified systems are 20% more effective than the best mixed air systems and can provide the same level of ventilation with a 16.7% reduction in air volume. This reduces the amount of outdoor air necessary to meet ventilation requirements. Figure 1. Mixed Air System In fully-stratified air distribution, cool supply air is typically delivered at reduced velocity from low sidewall diffusers. The supply air is always cooler than the room air, so it quickly drops to the floor and moves slowly across the room. When this slow moving air mass encounters a heat load, it rises and carries the heat and pollutants towards the ceiling. A layer of warm air forms above the occupied zone due to natural buoyancy. Internal heat loads and contaminants are carried away by the return air.

APPLICATION GUIDE

Displacement Ventilation

CONTAMINANT REMOVAL

Displacement ventilation can be a very effective strategy for removing contaminants from room air, because fullystratified systems take advantage of the fact that airborne pollutants are generally lighter than air. The natural buoyancy of tobacco smoke and human respiration allow these pollutants to rise above the breathing zone in plumes to the upper zone that forms below the ceiling. This upward migration of pollutants effectively increases concentrations in the unoccupied upper zone while reducing concentrations in the breathing zone.

TYPICAL APPLICATIONS

Ideal applications for displacement ventilation often involve large open spaces with tall ceilings. These include but are not limited to: • Theaters and performance halls • Meeting rooms and lecture halls • Restaurants and cafeterias • Hotel lobbies and atriums • Shopping malls • Gymnasiums • Casinos • Museums and exhibit halls • Classrooms • Airport terminals and train stations

BENEFITS AND LIMITATIONS

Typical benefits of displacement ventilation include: • Improved removal of airborne contaminants. • Greatly reduced energy requirements to cool occupied spaces in mild climates. • Reduced ventilation air requirement due to increased air distribution effectiveness. • Very low diffuser noise levels. • Reduced comfort complaints due to drafts.

Although displacement ventilation is well-suited for a wide variety of applications, the following spaces may be better served by mixed air systems: • Spaces with ceiling heights lower than 9 ft. • Spaces with occupied zone heat loads in excess of 30 Btu/hr-ft2. • Spaces furnished with cubicles or other partitions. • Spaces with ceiling heights lower than 10 ft that may be subject to significant room air disturbances. • Applications involving contaminants that are heavier and/or colder than room air in the occupied zone.

ENERGY CONSIDERATIONS

A couple of important considerations: • Displacement ventilation is not recommended for spaces where hazardous chemical spills could occur. In the event of a spill, a displacement ventilation system is likely to cause noxious fumes to be drawn from the floor and brought up to the breathing level, thereby increasing the possible hazard to occupants. • In rare situations where contaminants are heavier than air, accommodations should be made to allow some portion of the room air to be extracted at a lower level.

APPLICATION GUIDE

Figure 3. Contaminant Distribution in a Mixed Air System

Displacement ventilation can reduce energy use in several ways: • Increased economizer hours due to increased supply temperatures in comparison to conventional mixed air systems. • Chiller efficiency increases due to lesser dehumidification at higher water supply temperatures.

Displacement Ventilation

OUTLET CHARACTERISTICS

Displacement ventilation requires outlets that supply air at extremely low velocities, (typically 50-70 fpm). These outlets are typically located low on a sidewall or at the base of a column. The low average face velocity generally results in rather large diffuser panels. Since the outlets are located adjacent to the occupied zone and within easy reach of room occupants, they have the following special requirements: • Should be elevated above the floor to prevent damage from cleaning equipment. • Construction and finishes must be rugged enough to prevent damage through accidental or intentional occupant contact. • Should provide a concealed and tamperproof means of air pattern adjustment. • Face panel must be removable for cleaning and adjustment of air pattern controllers.

Figure 6. Standard Air Patterns

THE ADJACENT ZONE

The area immediately adjacent to a displacement ventilation outlet is known as ‘the adjacent zone’. This is any area in the occupied zone where local air velocities exceed 50 fpm at a height 1 in above the floor. Although this clear zone can often be in an aisle or corridor without creating potential comfort problems, stationary occupants should never be located within the adjacent zone. Cool air that drops from a sidewall diffuser and travels across the floor can easily be sensed by stationary occupants at the ankle level.

Figure 5. The Adjacent Zone It is important to note that all Titus displacement ventilation diffusers are supplied with adjustable air pattern controllers as standard equipment. The ability to adjust the shape of the air pattern and the adjacent zone can be of great benefit when dealing with furniture, occupants and obstructions especially in smaller spaces.

HEAT SOURCES AND CONVECTIVE FLOWS

The flow of convective heat is essential in establishing a fully-stratified system. As heat moves from warmer surfaces to the cooler surrounding air, the buoyancy of the air increases and the heat rises to create stratification in the occupied zone. This upward air motion driven by convection also results in room air entrainment that results in a larger heat plume. Although radiant heat sources do not directly affect these convective heat plumes, they may increase plume formation by increasing surface temperatures of heat sources.

AIR PATTERN PROJECTION

Although displacement ventilation is typically supplied from a low sidewall, the resulting room pattern is very different from a conventional sidewall grille. Because the supply air is cooler than the room air and is discharging at low velocity, it immediately drops to the floor. The air moves across the floor in a thin layer typically no more than 6-8 inches high. The diagrams above show why displacement ventilation is only recommended for cooling applications.

APPLICATION GUIDE

The characteristics of individual convective heat plumes may be influenced by each of the following: • Size and shape of heat source • Amount of heat available • Air motion surrounding heat source • Temperature gradient in the space Convective heat plumes will continue to rise until they reach a room level of equal temperature.

SPACE TEMPERATURE GRADIENTS AND AIRFLOW RATES

The distance from the floor to the upper mixed zone is known as the shift height. Since the design goal of a displacement ventilation system is to create temperature stratification throughout the occupied zone, it is critical that the shift height is greater than height of the occupied zone. Lower shift heights may be acceptable in situations where all occupants are seated.

Figure 9. Discharge Air Patterns This air pattern tends to stretch out and cover the entire room, even if the room shape is irregular. Obstructions such as partitions or furniture resting directly on the floor can result in coverage gaps, but the air pattern will rejoin itself much like fluid passing around an object. Displacement diffusers can typically provide coverage into a room that is up to six times the length of the adjacent zone. Internal heat load concentrations actually help to extend the projection of a displacement system by drawing the air across the room. Large rooms can be supplied from the side walls so long as the distance from the diffuser face to the furthest projection is no more than 30 ft. When room dimensions exceed 30 ft in length or width, it is best to place displacement diffusers on more than one wall. By placing diffusers on opposing walls, rooms up to 60 ft can be supplied from side walls. Another solution for large rooms is to place 360-degree diffusers throughout the interior space.

APPLICATION GUIDE

Displacement ventilation diffusers supply conditioned air at higher cooling temperatures (typically 62 to 70°F) and lower discharge velocities (less than 70 fpm) than ceiling diffusers. Since the supply air is always cooler than the room air, it can be said to cascade from the diffuser face to the floor. The negative buoyancy of the cooler air causes it to move at the floor level until it reaches a source of convective heat. As the supply air warms, its buoyancy increases to create a heat plume that rises to the upper mixed zone below the ceiling.

APPLICATION GUIDE METHODS OF EVALUATION

A successful displacement ventilation design should provide a supply airflow rate to meet the thermal gradient profile of an occupied space in accordance with ASHRAE comfort guidelines. ASHRAE Standard 55-2010 ‘Thermal Environmental Conditions for Human Occupancy’ recommends that vertical temperature differential between a seated occupant’s ankle and head regions (roughly 4 to 43 in) should be no more than 5.4°F to deliver acceptable comfort to 95% or more of the occupants. For a stationary standing person same guideline would apply over an elevation range of 4 to 67 in.

Displacement Ventilation low velocity and therefore do not generate audible noise. The catalog sound performance rating of a displacement diffuser is usually expressed in terms of a noise criteria (NC) level based upon a typical space with room absorption of 10 dB in each octave band per ASHRAE Standard 70-2006 (Appendix D). While this typical space effect has been used for many years to estimate the sound level of a diffuser serving a small office, this certainly isn’t the typical environment in which displacement ventilation is employed. Since we are often dealing with much larger spaces and taller ceilings, a different method must be employed to better estimate sound levels. A space effect for each octave band can be calculated based upon the size of the room and the distance between the source and observer using the following equation per AHRI Standard 885-2008: Space Effect = 25 – 10 log (ft) – 5 log (ft3) – 3 log (Hz) Where:

ft = Distance between the source and observer ft3 = Room volume Hz = Octave band center frequency

SUPPLY AIR CONNECTIONS

T12

Displacement ventilation diffusers are usually supplied by ductwork and they can be supplied from either above or below. • Optional telescoping duct covers are available to hide otherwise visible supply ductwork for a clean finished appearance. • Optional mounting bases (2-3/4 or 4 inch) are recommended to prevent possible damage due to traffic and floor cleaning equipment. These mounting bases are also recommended to simplify installation when air will be supplied from below. It is also possible to supply displacement ventilation diffusers from a pressurized plenum. • Care must be taken to insure that the supply plenum is tightly sealed. • In a properly designed supply plenum, pressures should be equal throughout and balancing dampers should not be required.

ACOUSTICAL PERFORMANCE

Like any building space, those supplied by displacement ventilation create an acoustical environment with contributions from air handlers, terminal units, diffusers and structure-borne sound. Properly sized and selected displacement ventilation diffusers are rarely the cause of noise complaints because they operate at low pressure and

When considering sound contributions from multiple diffusers, we can logarithmically add or multiply, but this is typically unnecessary. In large spaces, diffusers are rarely close enough together to contribute to the overall room sound level. As a general rule for smaller spaces, it is advisable to select diffusers for an NC level that is 10 points lower than the desired room sound level. This has the effect of masking the sound contribution of the diffusers in the background sound level. For larger spaces, the NC level of the diffuser is less critical because the room effect is so much greater.

DISPLACEMENT VENTILATION THEORY AND GOVERNING EQUATIONS

The following material is based on ASHRAE research project RP-949 that resulted in the ASHRAE publication ‘System Performance Evaluation and Design Guidelines for Displacement Ventilation’ (2003). This summary is intended to briefly explain the theory behind displacement ventilation. For a more detailed explanation including the derivation of each equation, the original publication is highly recommended. The design air volume supplied by a displacement ventilation system must be capable of meeting both the cooling and minimum ventilation requirements for a given space. In order to determine the cooling design air volume, the type, location and magnitude of all heat loads must be identified. These loads can be classified as: • Heat generated by occupants, desk lamps and office equipment, Qoe (Btu/h) • Heat generated by overhead lighting, Ql (Btu/h) • Heat from the exterior wall and window surfaces including transmitted solar radiation, Qex (Btu/h)

APPLICATION GUIDE

Displacement Ventilation

The heat transfer to the region of interest can therefore be calculated by the following equation: ∆Thf ρCpV = аoeQoe + аlQl + аexQex

Vh = (0.295Qoe + 0.132Ql + 0.185Qex)/(∆Thf ρCp) With the following assumptions: • ∆Thf = 3.6 °F (for a seated occupant) • ρ = 0.075 lb/ft2 • Cp = 0.24 Btu/lb-°F This equation can be simplified to: Vh = 0.076Qoe + 0.034Ql + 0.048Qex This equation is very useful for typical applications involving seated occupants.

Where: • ∆Thf = temperature differential between the head and foot level of occupant (°F) • ρ = air density under standard conditions (lb/ft3) • Cp = specific heat of air at constant pressure (Btu/lb-°F) • V = supply flow rate (ft3/h)

The required ventilation rate can be determined by consulting ASHRAE Standard 62.1-2010. This standard provides recommended ventilation rates for various room occupancies and applications (Table 6-1). These recommendations involve the minimum ventilation rates in the breathing zone based upon both occupant density and floor area.

Since:

The breathing zone outdoor airflow (cfm), Vbz, can be calculated using the following equation:

V = nHA Where: • n = the required air change rate (ach) • H = space height (ft) • A = floor area (ft2) The heat transfer equation can be simplified to: ∆Thf = (аoeQoe + аlQl + аexQex ) / (ρCpnHA)

The same equation can be used to calculate the required ventilation rate: n = (аoeQoe + аlQl + аexQex ) / (∆Thf ρCpHA) The cooling air volume (cfm), Vh, for a typical office environment can then be calculated using the following equation: Vh = nAH/60

Vbz = (Rp x Pz ) + (Ra x Az ) Where: • Rp = people outdoor air rate from Table 6-1 (cfm/person) • Pz = zone population (#) • Ra = area outdoor air rate from Table 6-1 (cfm/ft2) • Az = zone floor area (ft2) ASHRAE Standard 62.1-2010 also defines air change effectiveness (Ez) of various types of air distribution systems (Table 6-2). While the best mixed air system with ceiling diffusers can only achieve a rating of 1.0, displacement ventilation systems achieve a 1.2 rating. This means that a displacement ventilation system can meet ventilation requirements with 16.7% less air volume than a mixed air system. Be aware that local code requirements may be more stringent than the minimum standards recommended by ASHRAE and may not differentiate between system types and air change effectiveness. The zone outdoor airflow requirement (cfm), Voz, can be calculated as: Voz = Vbz / Ez Where: • Ez = air change effectiveness from Table 6-2 The supply air volume (cfm), V, will be larger of either the cooling air volume (cfm), Vh, or the zone outdoor airflow requirement (cfm), Voz. Be aware that if a dedicated outdoor air system (DOAS) is employed, then supply air volume, V, would consist of 100% outdoor air. If return air is being

APPLICATION GUIDE

ASHRAE Standard 55-2010 recommends that for good thermal comfort the temperature difference between the head and foot level of a standing person should not exceed 5.4 °F. In a stratification zone, assume that the temperature gradient will be less than 1 °F/ft. Since the vertical temperature gradient between a seated person’s head (3.6 ft) and a standing person’s head (5.6 ft) is generally less than that between the ankle level (0.3 ft) and seated person’s head (3.6 ft), any design that meets the seated recommendations should also be suitable for a standing person.

Substituting the ventilation rate, n, into the equation yields: A weighting factor must be applied to each of these loads to properly approximate the effect of each type of load entering the region between the head and the feet of a seated occupant. Based on ASHRAE research, these weighting factors are: • Occupants, desk lamps and office equipment, аoe = 0.295 • Overhead lighting, аl = 0.132 • Exterior wall and window surfaces including transmitted solar radiation, аex = 0.185

Ts = Tsp – 3.6 – ((AQt )/(2.59V2 + 1.08 AV)) The exhaust air temperature, Te, can be calculated as:

Flat front or bow-fronted diffusers either flush-mounted or surface-mounted would be best. The exact model choice comes down to appearance and architectural limitations. The best arrangement would be to place pairs of diffusers on opposite walls such that they discharge down the aisles between work stations. This would require four diffusers each handling 316 cfm, selected for an adjacent zone with a depth of less than 4-5 ft. This should be adequate to achieve coverage to the center of the room. Since the ideal sound level for an open plan office is NC40, the diffusers should be selected for NC30 or less. See Figure 12 for example of diffuser layout.

Step 1 – Calculate the Total Cooling Load Qt = Qoe + Ql + Qex

APPLICATION GUIDE

This is a conference room with an exterior window. The room is equipped with a computer and a projector and is intended for a maximum occupancy of twelve. It measures 30 ft by 15 ft by 10 ft (L x W x H). The window is located on the longest wall. The room will be supplied by a conventional air handler that will mix return air with outdoor air. Assume: • Occupancy = 12 • Load per person = 250 Btu/h • Overhead lighting load = 2 watts/ft2 = 6.826 Btu/h-ft2 • Computer load = 65 watts = 222 Btu/h • Projector load = 200 watts = 683 Btu/h • Solar and glass load = 4.0 Btu/h-ft2

Step 4 – Calculate the Zone Outdoor Airflow for Acceptable Indoor Air Quality The zone outdoor airflow requirement (cfm), Voz, and the breathing zone outdoor airflow (cfm), Vbz, can be determined from ASHRAE Standard 62.1 (Tables 6-1 and 6-2) and the following equations:

Voz = Vbz / Ez Where: • Ez = air change effectiveness from Table 6.2 = 1.2

APPLICATION GUIDE

Voz = 72.5 cfm Step 5 – Determine the Supply Air Volume The supply air volume, V, will be larger of either the cooling air volume, Vh, or the zone outdoor airflow requirement, Voz. V = 459 cfm Since the air handler will be mixing return air with outdoor air, we must calculate the required percentage of outdoor air to satisfy the zone outdoor air requirement, Voz. Voz / V = 16% Step 6 – Calculate the Supply Air Temperature The supply air temperature, Ts, can be calculated as: Ts = Tsp – 3.6 – ((AQt )/(2.59V2 + 1.08 AV)) Where: • Tsp = room temperature = 72 °F Ts = 64 °F Step 7 – Calculate the Exhaust Air Temperature The exhaust air temperature, Te, can be calculated as: Te = Ts + ((Qt )/(1.08V)) Te = 80 °F Step 8 – Select Supply Diffuser(s) The best choice for this application would be a pair of 90-degree air pattern diffusers located on the interior corners of the room. Each diffuser will handle 230 cfm and should be selected for an adjacent zone no deeper than 4-5 ft. Since the typical sound level for a conference room should not exceed NC30, the diffusers should be selected for NC20 or less. See Figure 13 for example of diffuser layout.

V = 2017 cfm Since the air handler will be mixing return air with outdoor air, we must calculate the required percentage of outdoor air to satisfy the zone outdoor air requirement, Voz.

The room is equipped with (5) computers, (5) monitors and a projector. It measures 30 ft by 30 ft by 10 ft (L x W x H). The room will be supplied by a conventional air handler that will mix return air with outdoor air. Assume: • Occupancy = 26 • Load per person = 250 Btu/h • Overhead lighting load = 2 watts/ft2 = 6.826 Btu/h-ft2 • Computer load = 65 watts = 222 Btu/h • Monitor load = 30 watts = 102 Btu/h • Projector load = 200 watts = 683 Btu/h • Solar and glass load = 10.5 Btu/h-ft2

The most common diffuser arrangement for this room layout would require a diffuser on each side of the teacher’s desk discharging down the side aisles. Each diffuser would handle 515 cfm and the adjacent zone depth should be no more than 4-5 ft. Since sound levels in elementary school classrooms are critical to the learning environment and are recommended not to exceed NC25-30, the diffusers should be selected for NC15 or less so as not to be heard. See Figure 15 for example of diffuser layout.

Where: • Rp = people outdoor air rate from Table 6-1 = 5.0 cfm/person • Pz = zone population (#) = 1 • Ra = area outdoor air rate from Table 6-1 = 0.06 cfm/ft2 • Az = zone floor area (ft2) Vbz = 368 cfm Voz = Vbz / Ez

• A single blade damper rotates to shut off the front (cooling) or rear (heating) plenum. The damper is driven by a 24 volt motor/actuator that provides the auto-changeover action for the cooling/heating applications (transformer by others). • Available in two sizes: 36x79 with 14” diameter inlet, 47x79 with 24” x 8” inlet.

• Optional duct cover and mounting base available as accessories. • Material is galvanized steel and aluminum.

Cooling Mode

• The dual plenum design features a front plenum ducted to a displacement diffuser at the top and rear plenum ducted to a CT diffuser at the bottom of the unit.

• The DVRI-HC uses displacement principles to cool and mixed airflow principles to heat from a single unit assembly with one inlet connection.

All dimensions are in inches.

DVRI-HC PLEXICON

Heating Mode

• The Titus DVRI-HC “Plexicon” is a combination displacement/ mixed air diffuser that can be positioned against a wall in flush or surface mount applications to provide cooling and perimeter heating in the space.

Overview

The chilled ceiling products provide sensible cooling and heating to the space by utilizing the more efficient heat transfer capacity of water, as opposed to air. This decouples the latent and sensible loads, reducing the energy cost of sensible cooling. With passive beams and radiant products, an additional system is necessary to meet the ventilation and latent cooling needs of the space. The Titus active chilled beams integrate the supply of ventilation air creating an active diffuser. Using the ventilation air to pressurize a plenum with aerodynamically designed nozzles, high velocity jets of air are created forcing induction of room air over the water coils integral to the units. Forced induction dramatically improves the heating and cooling capacity over passive beams and radiant products. Titus active chilled

beams harness the energy of the supply air to further reduce total energy consumption. Titus offers a chilled ceiling product to meet the requirements of any design or installation. Just a single model of passive beam accommodates both exposed and recessed mounting applications. Active chilled beams are available in 1, 2, and 4-way throw patterns. There is even a model for high sidewall applications. In addition to the variety of product solutions available, the appearance of the units can be customized through standard options, which enables seamless integration into any architectural style, traditional or contemporary.

APPLICATION GUIDE

Introduction Chilled ceiling systems consist of three main product types: active chilled beams, passive chilled beams, and radiant ceiling panels/sails. Even though these units are commonly referred to as “chilled” products they are also effectively used for both cooling and heating. Both active and passive beams utilize water coils to provide sensible cooling, reducing the total load that must be addressed through the building’s air handlers. Since chilled beams provide sensible only cooling they are best suited for spaces with low to moderate latent loads. This offers considerable potential for energy savings due to the volumetric heat transfer capacity of water and trade-off between fan energy and pumping power.

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. The ceiling panels emit cooling and heating to the surrounding surfaces in the area by radiation. Radiant heat transfer typically results in high thermal comfort since the ambient temperature will feel 2.5BF to 5BF cooler/ warmer than actual room temperature. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

Passive beams consist of a water coil and an enclosure. The enclosure is primarily cosmetic, but helps to maintain even heat transfer across the coil. Passive beams provide cooling primarily through convective heat transfer. A convection current is created where higher density cool air sinks into the space, inducing warm low density air at the ceiling level through the coil. When using passive beams ventilation air must be introduced to the space either through natural or mechanical means.

History

APPLICATION GUIDE

Modern chilled ceiling systems, more specifically active chilled beams, got their start in the 1920s when Willis Carrier began to develop the concepts for under-sill induction units. Patents were applied for and first installations of these units were completed in 1940. The use of an air-water terminal located in the space was an important advance in and of itself; however, these systems solidified the advantages of an air-water system over an all-air system.

Incorporating supply air into a beam creates an active diffuser. Ventilation air pressurizes a plenum and the aerodynamically designed jets induce room air over water coils. Forced induction dramatically increases the heating and cooling capacity per square foot, compared to passive beams and radiant products. Active chilled beams harness the energy of the supply air to further reduce total energy consumption.

• Water is much more efficient heat transfer medium than air. • Reduced duct size required to only supply ventilation air increased usable space, and reduced the material cost and installation time. Scandinavian engineers, during the mid-1970’s, adapted this technology along with radiant heating/cooling panels for overhead applications to work with new buildings designed to utilize natural ventilation. The result of their efforts was the passive chilled beam. In regions where using natural ventilation was not effective, engineers integrated the mechanical ventilation into chilled beam. Utilizing the same principles used in the under-sill induction boxes, the active chilled beam was developed.

APPLICATION GUIDE

HEAT TRANSFER

ASHRAE defines heat transfer as “the flow of heat energy induced by a temperature difference.” Thermal energy can be transferred or be affected by: • Conduction • Convection • Radiation • Humidity Thermal conduction is the mechanism of heat transfer by the transfer of kinetic energy between particles or groups of particles at the atomic level. With solid bodies, such as with an air jet near a window, thermal conduction dominates only very close to the solid surface. Thermal convection is the transfer by eddy mixing and diffusion in addition to conduction. The transfer of fluid currents produced by external sources, such as by a blower, is called forced convection. When the fluid air movement is caused by the difference in density and the action of gravity, it is called natural convection. Natural convection is very active near windows and near heat sources in the occupied spaces. The colder air falls and the warmer air rises. Radiant heat transfer takes place through matter. It is a change in energy form, from internal energy at the source to electromagnetic energy for transmission, then back to internal energy at the receiver. Examples of radiation are sunshine through the air and window to the inside floor or ceiling light to occupants and to the floor. All of these methods of heat transfer effect a person’s comfort reaction. In addition, humidity has some effect caused by a change in evaporation rate from the body.

Heat loss is measured in “BTU” which is the amount of heat required to raise 1 lb. of water 1BF. Coefficients used to estimate the value of the heat loss include: • ‘K’ Factor: amount of heat transferred in 1 hour through 1 sq. ft. of material, 1” thick at 1BF of temperature difference.

Equation 1: For a structure with multiple skin materials, the total heat transmission can be calculated as: U = 1/(R1 + R2 + …..Rn) For hydronic heating and cooling systems heat is removed from the occupied space (cooling) or added to the occupied space (heating) via a closed loop water system. Return air from the space passes across a fin tube coil.

PSYCHROMETRICS

One of the four major elements of thermal energy and comfort is humidity. Psychrometrics uses thermodynamics properties to analyze conditions and processes involving moist air. A detailed study of psychrometrics can be found in Chapter 1 of ASHRAE 2009 Fundamentals Handbook. This section is a summary of how knowledge of psychrometrics can be used to maximize space comfort and system performance.

Atmospheric Air (the air that you breathe), contains many gaseous components including water vapor and containments. Dry Air is atmospheric air with all moisture removed and is used only as a point of reference. Moist Air is a combination of dry air and water vapor and can be considered equal to atmospheric air for this discussion. A psychrometric chart (FIGURE 4) is a graphical representation of the thermodynamic properties of moist air. There are several charts available to cover all common conditions. The one shown here is taken from ASHRAE Fundamentals Handbook, Chapter 1 and illustrates conditions of 32 to 100BF at sea level. The Dry-bulb Temperature (DBT), is the temperature measured using a standard thermometer. Dry-bulb is also known as the sensible temperature. The Wet-bulb Temperature (WBT), is the temperature measured using a ‘wetted’ thermometer. Wet-bulb is used to determine the moisture content of air. The Absolute Humidity (AH), is the vapor content of air. It is described in terms of moisture per lb of dry air or grains of moisture per lb. of dry air. AH is also referred to as ‘moisture content’ or ‘humidity ratio.’ There are 7000 grains in a lb. of water. The Relative Humidity (RH), is the vapor content of air. It is described as the percentage of saturation humidity at the

APPLICATION GUIGE

Heat transfer is also affected by the following factors: • A greater temperature difference will result in a greater amount of heat transfer. • The amount of surface area is directly proportional to the amount of heat transfer. • The amount of time is also directly proportional to the amount of heat transfer. • The thermal resistance of the material use affects the rate of heat transfer.

• ‘C’ Factor: amount of heat transferred in 1 hour through 1 sq. ft. of material through the specified thickness of the material used. • ‘R’ Value: resistance to heat transfer, measured as the reciprocal of conductance (1/K or 1/C). • ‘U’ Value: designates the overall transmission of heat in 1 hour per sq. ft. of area for the difference of 1BF across specified material. • Conductance of individual materials is not directly applicable to the heat loss calculation. First, it must be converted to the ‘R’ value, which is (1/K or 1/C).

increase in specific volume. The Enthalpy (H) is the heat content of air. Enthalpy is also known as the total heat of air. Enthalpy is defendant on the wet-bulb temperature of air. It is described in terms of Btu’s per lb. dry air (Btu/lb.).

The Dew Point Temperature (DPT), is the temperature at which vapor begins to fall out of air to form condensation. DPT is the temperature at which a state of saturation humidity occurs, or 100% RH. It is also known as the saturation temperature.

A Status Point is a location on the psychrometric chart defined by any two psychrometric properties. A hydrometer or psychrometer is commonly used to define a status point. At 100% RH the wet-bulb will equal the dry-bulb temperature. As the temperature difference between temperatures increases, the RH will decrease.

The Specific Volume (Spv), is the reciprocal of air density which is described in terms of cubic feet per lb of dry air (cu ft/lb.). An increase in air temperature will result in a decrease in density and an increase in volume. A decrease in atmospheric pressure also decreased air density while increasing volume. At 5000 feet above sea level, density is decreased by 17%. Higher altitudes require larger motors and blowers to move the same effective mass, due to the

To locate a status-point, find the dry-bulb temperature on the bottom of the psychrometric chart. Follow this line upward until it intersects with the wet-bulb temperature from the left side of the chart.

APPLICATION GUIDE

When will condensation occur? To determine if a supply air duct or air outlet device will form condensation on the surface: First, using the R-value of any thermal barrier, determine the minimum surface temperature. Next, determine the DPT of the atmospheric air in contact with the surface. If the surface temperature is equal or lower than the DPT, the surface will form condensation. If yes, an additional thermal barrier or other condensation prevention strategies may be required to solve the problem. Sensible heating (Qsen), is the heat that raises the dry-bulb temperature of air without increasing the moisture content. Because we can easily sense this change in temperature, it is called ‘sensible.’ Sensible cooling is the removal of heat without removing moisture content of the air. Latent Heat (Qlat), is the heat content of air due to the presence of water vapor. Latent heat is the heat required to evaporate this same amount of water (970 Btu/lb), also known as the latent heat of vaporization. As latent heat increases, moisture content increases. Water can be heated to 212BF. If more heat is added, the water will vaporize but the temperature will not change. Latent Cooling (Qlat), is the removal of latent eat from air without lowering the dry-bulb temperature. To retrieve 1 lb. of condensate, 970 Btu’s would need to be removed. As latent heat decreased, moisture content decreases.\

Sensible processes can be shown as horizontal paths on a psychrometric chart. Latent processes can be shown as vertical paths on a psychrometric chart. Most processes include both, resulting in an angled or diagonal path. Sensible heat factor (SHF) is the measure of sensible heat to latent heat. Sensible heating only is 1.0. Equal proportions result in 0.5. SHF is generally higher than 0.5 because of the cooling processes that remove more sensible heat than latent heat.

INDUCTION

Induction is a flow that occurs as a result of the change in velocity pressure as a jet of air expands. The principals of induced air flow are based on the Venturi effect. The

Benefits of Chilled Ceiling Systems Chilled Ceiling Systems are designed to provide superior occupancy comfort. These systems require less energy to operate, operate more efficiently, and use less materials than conventional all air systems. Tempered and dehumidified air is supplied to the space to meet ventilation requirements and to handle the latent load. The majority of the sensible load is addressed with the chilled ceiling products. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced volume of air that must be delivered to the space results in reduced air handler capacity and size, smaller duct sizes, and overall energy savings. A higher supply temperature contributes to increased occupancy comfort.

FIRST COST BENEFITS:

• Shallow unit profiles allow for reduced ceiling space requirements; typically require 60% less vertical space than conventional all air systems. "" Reduced slab to slab spacing; reducing material costs per floor. "" Easily integrated into retrofit applications where space is limited. • Low volume of supply air required for active beams enables reduction of the total amount of air processed at the air-handler by an all air system up to 50%. "" Reduced air-handler size/ capacity, and duct work size

COMFORT AND IAQ BENEFITS:

• Active beams typically supply a constant volume of primary air, decreasing occurrences of dumping and changes to the air motion in the space; issues common to typical VAV systems. • When supplied with primary air from a dedicated outside air system (DOAS) 100% fresh air is supplied to the space. • Dry-coil sensible cooling, eliminates bacterial, fungal, or mold growth associated with fan coils and other unitary products with condensing coils. • Constant primary air volume ensures ventilation requirements are met and helps to maintain relative humidity levels in the space.

APPLICATION GUIGE

Latent Heat of Fusion is the heat required to change a liquid into a solid (144 Btu/lb. Water can be cooled to 32BF. If more heat is removed, it will cause ice to form. To retrieve 1 lb of water from ice, 144 Btu’s must be added.

Venturi effect is a derivation of Bernoulli’s principle and the continuity laws. In order to satisfy the fluid dynamic principles of continuity, a fluid’s velocity must decrease as the flow expands; at the same time the static pressure of the flow must increase. The increase in static pressure balances the decreased velocity, thus maintaining the principles of conservation.

Chilled Ceiling System Design CHILLED CEILING APPLICATIONS

APPLICATION GUIDE

Chilled beam and radiant ceiling products are designed to handle high thermal loads in the space. They are also an effective solution in spaces where individual temperature control is desired. Ideal applications are spaces where the sensible heat ratio is greater than 0.75, meaning that 75% or more of the total heat gains in the space are sensible gains. These locations include computer/server rooms, condos/apartments/hotel guest rooms, libraries, and museums.

U10

Use of chilled ceiling systems should be limited to applications where cooling loads are less than 40 BTUH/ ft2, and heating loads are lower than 15 BTUH/ft2. More specifically, passive beam and radiant panel usage should be limited to applications where cooling loads are no more than 25 BTUH/ft2, and active chilled beams are not recommended for use when cooling loads are more than 40 BTUH/ft2. Chilled ceiling systems are not recommended in these applications since addressing the loads will likely create thermal comfort issues. In transitional spaces where thermal comfort is not critical, chilled ceiling products can be used to address higher loads. Chilled beams and radiant ceiling systems should not be applied in buildings where relative humidity of the space is not easily maintained. This would include retrofit applications, lobbies, and entrances where there is excessive infiltration. Chilled beams are best applied when installed no higher than 14 feet above the floor, but can remain effective with installation heights up to 20 feet. When installed above these heights it is difficult to effectively get heating and cooling into the occupied space.

There are guidelines that should be followed when considering a chilled ceiling system to ensure the design will create a comfortable environment for occupants and result in optimum energy efficiency. The system should be designed to meet only the heating and cooling requirements of the actual space. Overdesigning the system will increase the cost of the project, and potentially result in decreased comfort. Primary air must be adequately dehumidified, and supplied at a flow rate large enough to offset the latent loads of the space. This flow rate must also be high enough to meet the ventilation requirements outlined in ASHRAE standard 62.1. When heating with chilled beams and radiant panels, care must be taken that the system is not oversized for heating. Entering water temperatures should be as low as possible to meet the heating requirements, and should never be over 140BF. Condensation control strategies must be implemented to maintain optimum operating conditions, prevent bacterial, mold, and fungus growth, ensure damage to building does not occur. When designing a chilled beam system it is best to limit the types and configurations of products used. This will help to make logistics during installation and building maintenance easier. Room air temperature is maintained through regulation of 2-way control valves. Use of 2-way valves is preferred as they will minimize pumping costs. Systems should be designed to take full advantage of free cooling and heating opportunities through economizers and heat recovery devices. Chilled beams and radiant panels are highly efficient products and offer energy savings over traditional systems. However, one of the biggest advantages these products offer is the additional energy savings that can be achieved in the rest of the system due to the unit operating conditions.

DESIGN METHODOLOGY

The design of chilled ceiling systems is an iterative process between selection of the equipment to be used and the inlet conditions for the system. This also includes placement/ orientation. The iterative process enables the inlet conditions to be optimized so that the design results in a comfortable space for the occupant, and that the equipment is operating with the highest efficiency possible. This is true for all chilled ceiling systems, but is especially true for active chilled beams. Equipment selection is based on the following items and must be balanced for creating an effective, efficient, and comfortable system:

The critical points to be maintained are the entering water conditions as well as the supply air conditions. After control of the critical points has been established, additional controls to compensate for changes in space dew point temperature and occupancy should be considered through a building management system. This methodology is depicted in Figure 5, Chilled Ceiling Design Methodology.

System Design Process U12

SPACE DESIGN CONDITIONS

The first step in determining the space design conditions is to define the design temperatures for both heating and

cooling. This should be done by following the guidelines set in ASHRAE Standard 55 and the chapters on heating and cooling loads in the ASHRAE Fundamentals Handbook. Once the design temperatures have been defined, an iterative process should be used to determine the indoor air quality requirements, calculating the required capacities to address the heating/cooling loads, and adjusting the building design/construction (if applicable). The indoor air quality (IAQ) requirements include supply air flow rate, to meet both ventilation requirements and address the latent loads in the space, determining infiltration, and defining the maximum allowable humidity level. Based on the building design and construction, anticipated infiltration should be calculated. Information on how to calculate infiltration and how to use infiltration when calculating heat loads and losses can be found in the ASHRAE Fundamentals Handbook. The heat loads and losses calculated associated with infiltration are used in determining the latent cooling requirements. This will affect the volume of supply air necessary to maintain the design humidity levels in the room. Guidelines for determining the minimum ventilation requirements are given in ASHRAE Standard 62.1. Criteria for maximum relative humidity in the space, based on a humidity ratio of 0.012, is set in ASHRAE Standard 55; for a room design temperature of 75BF, the maximum relative humidity is 63.5%. Once the design conditions for room relative humidity have been determined the supply air flow rate necessary to maintain this level can be calculated. The required flow rate to meet the latent load can be determined by the following equation on the next page:

APPLICATION GUIDE

. V = the volumetric flow rate, CFM . q = latent heat gain in the space, BTU/H HRr = room air humidity ratio, lbs water/lbs dry air HRp = primary air humidity ratio, lbs water/lbs dry air It follows that the required flow rate to maintain control of the humidity will rapidly increase as the difference between the room air and primary air humidity ratios decrease. As a result, designs seeking to maintain relatively low humidity ratios will need a high primary flow rate if the dew point temperature of the supply air is close to the design dew point in the room. Comparing the required supply airflow rates for ventilation and to maintain the relative humidity of the space, the higher of the two flow rates will determine the minimum flow rate allowable for the space. If necessary the supply air flow rate can be increased to supplement the sensible cooling of the products selected. After the IAQ requirements have been tentatively set, the required equipment capacities to meet the heat loads and losses can are determined. Care should be taken to design around actual loads/losses that will be experienced in the space. Overdesigning the system will increase installation and equipment costs, and could potentially cause thermal comfort issues. Once the capacity requirements have been calculated, either supply air conditions or building design/ construction (if possible) can be adjusted to be more suited to chilled ceiling application.

PRODUCT SELECTION

The type of product to be used to is at the designer’s discretion. However the recommended limitations of maximum capacity per square foot should not be exceeded where high levels of thermal comfort are required.

There are several ways to operate these products to prevent condensation. The primary step to preventing condensation is for the chilled water design supply temperature to be at least 1BF above the dew-point temperature of the space. Also, the supply air to the space must also be sufficiently dehumidified to maintain the design relative humidity conditions. The secondary measures are noted below:

At this time the supply air temperature should be tentatively selected. Supply air temperature can be varied between cooling and heating, but most designs keep a fixed temperature as long as heating requirements can be met. The size and configuration of products selected should be completed while adjusting the following parameters: • Water flow rate: this should be selected to minimize pressure drop, should be no higher 10 ft w.g., while maintaining turbulent flow through the product. • Supply airflow rate: flow rate must be maintained above the minimum determined for IAQ requirements, but can be increased to offset the sensible cooling requirements of the product selected "" Increasing the flow rate in active beams while maintaining the same nozzle geometry will result in an increase of operating pressure. The recommended operating range is typically between 0.2 in w.g. and 0.8 in w.g. Operating pressure in active beams will also directly impact the noise generated by the product during operation. • Unit placement/Configurations: "" Radiant panels and sails: These products should be installed so that no more than 75% of the available ceiling space is made up of active panels/ sails. Panels models with perforated faces and backed with acoustic fleece insulation can be used to improve noise attenuation within the space. "" Passive Beams: Passive beams should not be installed directly above occupants since the highest velocities occurring from the convection process will occur directly underneath the beam. "" It is critical to the operation of passive beams that adequate space is provided for air flow through the beam. When installed in a flush mount application, shadow gaps, perforated ceiling tiles, dummy beams, or return air grilles must be installed so that warm room air enter the air path for the passive beams. It is recommended that the total free area for the return air path be at least 50% of the passive beam surface area. In exposed applications, the beams should be installed with a minimum distance between the top surface of the beam and the ceiling that is equivalent to half of the beam width, see Figure 7.

APPLICATION GUIGE

Once product type has been decided the entering water temperature should be selected such that condensation is prevented. The majority of chilled ceiling products do not include a means to collect or manage condensation. This means the temperature of the heat transfer surface, either water coil or panel/sail surface, must be higher than the dew-point temperature of the space to prevent the formation of condensation. However, to achieve the maximum cooling capacity the entering water temperature should be as low as possible. This can be difficult when trying to get the most capacity out of chilled ceiling products.

• Properly insulated valves and piping • Measures used to shut off chilled water flow "" Condensation sensors installed on the supply water piping "" Relative humidity/dew-point temperature sensor installed in the return air path • Raising the chilled water supply temperature "" Using a relative humidity sensor in conjunction with a room temperature system to determine moisture content and dew-point temperature of the space. Using this information the chilled water temperature can be adjusted upward to prevent condensation. This measure should only be used in the event that an entire building is at risk for condensation.

Figure 7. Passive beam mounting height "" Active Beams: With the different configurations available in active beams, 1, 2, and 4-way beams a design can be implemented to effectively create a comfortable space. In open office spaces as well as internal offices 2-way or 4-way beams are typically used. The flexibility provided by 2-way and 4-way beams, due to multiple sizes and nozzle configurations, allow them to be appropriately applied in most applications. 1-way beams are typically used in perimeter zones and small spaces such as individual offices and hotel rooms.

www.titus-hvac.com | www.titus-energysolutions.com

"" After the throw pattern has been decided, placement of the beam within the space can be determined. Active chilled beams, because of their design, share throw characteristics with conventional slot diffusers. Placement and orientation of active beams is critical for thermal comfort due long throw values associated with active beams. In open office plans it is typically more cost effective to use several longer beams that are installed parallel to the long direction of conventional ceiling systems, instead of numerous smaller beams the length of the module division. (Figure 8, Openoffice Active Beam Layout) However in an open office the number and size of beams used will be determined by balancing the cost per beam, cost of air side operating pressure, and water side pumping power to achieve optimum energy efficiency. "" When applying 2-way and 4-way beams in small offices and individual offices the recommended location is directly above the occupants. This will result in the lowest velocities within the occupied space. It is also recommended that 2-way beams are installed lengthwise in the space. This will allow for the use of longer beams, reducing the cooling requirements per linear foot which will inturn lower total air flow per foot and the resulting velocities in the space ensuring occupancy comfort. If placement is required near a wall use of 1-way throw beams are recommended. 1-way beams can also be effectively used in perimeter zones for cooling applications; however they should be supplemented with baseboard heating to address window loads during the heating season. 2-way beams can be effectively applied in perimeter zones for both heating and cooling. Care must be taken if 2-way beams are installed parallel to windows. In intermediate seasons when internal cooling is required and window surfaces are cool an acceleration of the air can occur in the space creating drafts and potential discomfort.

APPLICATION GUIGE

Figure 8 - Open-office Active Beam Layout: In lengthwise installations(a) there are less piping and duct connections than in crosswise installations(b). In crosswise installations, there is typically one beam per module. Even if the total cost for the beams in both layouts are the same, installation costs, additional valves, piping, and ductwork will prove to be more costly.

Occupied Zone

The minimum distance between units (2X) or minimum distance from a sidewall (X), can be determined by taking the difference between the diffuser's characteristic throw to 50 fpm (T50 ) and the distance between the ceiling and the occupied zone (Y). Figure 9. Local Velocity Diagram "" The ideal location for most active beams is directly above the occupant. This is because the lowest velocities in the space will occur in the induced air path. If it is desired to position an active beam close to a wall, a unit with an asymmetrical or 1-way throw pattern is recommended. As active chilled beams have throw characteristics similar to linear slot diffusers the same principles for determining thermal comfort conditions should be used. Location for final placement should take into consideration the allowable average air speed in the occupied space in accordance with ASHRAE Standard 55. Accounting for the air side sensible capacity will allow for reduced capacity requirements of the water coils in the beams. Designing with this in mind will reduce airflow requirements per linear foot, which will help to meet the requirements for thermal comfort. When placing two beams in the same space as shown in Figure 9, Local velocity diagram, care must be taken to ensure that the colliding air streams do not result in velocities over 50 fpm causing discomfort. A general guideline to achieve air velocities of 50 fpm or less in the occupied space is to ensure the velocities of colliding airstreams are below 100 fpm. If velocities at the point of collision are greater than 100 fpm, the distance from the ceiling for the air flow to slow to 50 fpm is noted in the equation below: Y=T50 - X Where: Y = distance from the ceiling X = half the distance to the adjacent diffuser T50 = diffuser characteristic throw to 50 fpm

CONTROL OF CHILLED CEILING SYSTEMS

Very basic room controls can be used with chilled ceiling systems. This is due to the fact that most systems are designed to operate with a constant volume of supply air. Also, the large coil size, combined with relatively low velocities across the coils result in a fairly long response time. With chilled beams or radiant systems, the most common method for controlling room temperature is regulating the water flow rate through the selected equipment. The alternative is to vary the supply water temperature. The control of water flow rate is achieved through onoff, time proportional on-off, or modulating control valve actuators. The maximum flow rate should be limited by a balancing valve installed on each beam circuit. It is generally recommended for 2-way valves to be used to reduce pumping costs, but 3-way valves can be used when pump speeds are not variable. While on-off and modulating actuator control is straight forward, time proportional on-off systems are a bit more complex. These systems use a feedback control loop to open and close an on-off actuator such that the total time open is proportional to the percentage of flow that is requested by a modulated room controller. While control of this system is more complex, actuator first costs are greatly reduced. Chilled beams should be connected in parallel so that each beam sees the same entering water temperature. For the greatest flexibility of control each beam should be fitted with an actuated control valve. With this setup, the flow rate can be modulated in each beam. And, in the event the entering water temperature reaches a point where condensation is a concern the flow rate to individual units affected can be shut

When designing systems with occupied/unoccupied modes or with night set back set ups. It is critical to ensure the design relative humidity conditions are met prior any water based sensible cooling. In most cases, 30 minutes of dryair ventilation will be enough to prevent any condensation during morning start-up and when returning to occupied modes. This can easily be achieved for night set back/ morning start up by offsetting the time schedules for the air handlers and chilled beam system pumps.

Alternatively to varying water flow rate through the beam, the entering water temperature can be varied according to the load in the space. This requires more sophisticated control sequences. Varying the water temperature also requires a bypass loop, that can inject higher temperature water from the return loop of the chilled beams or main air handler into the supply water loop for the beams. In order to control the supply water temperature a dedicated chiller and supply/return circuits can be used (see Figure 11a), or heat exchanger between the main air

• Standard finish is RAL 9010 white paint on diffuser face. • Diffuser is designed to fit into standard module ceiling grids 24” or 12” in width.

DESCRIPTION

The DISA active chilled beam diffuser was developed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings. In the primary distribution channel, CNC formed nozzles are precisely arranged. The number and size of nozzles (A, B, C, D) can be varied, thus allowing optimum adjustment of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, whichever is greater, total system energy costs are reduced.

DISA

The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced over a horizontally mounted heat exchanger, to address sensible loads in the space. The primary air is mixed with the cooled secondary air and supplied to the room through 1- or 2-slot diffusers integrated into the unit design. The DISA chilled beams are available in a multitude of configurations, resulting in produces that easily integrate into any building or design. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. The low overall height of the DISA product line is ideal for reducing the space required for false ceilings in new buildings and for retrofit applications.

INSTALLATION

U18

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system

in parallel. It is recommended that DISA chilled beams are connected to a supply air duct system which controls the supplied primary air volume. When integrated with room controllers, the units can be used both for single room and zone control.

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • The height of the air duct system is reduced to a minimum, due to the low supply of primary air. • Substantial reduction in the operating costs, due to low primary air volume. • Improvement of the thermal comfort inside the room. • Individual adjustment of the primary air volume by means of the nozzle configuration A, B, C, D. • Suitable for all standard ceiling grids.

Linear Active Chilled Beams (continued)

• DISA-V is a linear sidewall active chilled beam diffuser with horizontal air distribution. DISA-V

• Unique linear design provides high induction and low noise levels. • Configurable as cooling & supply air (CO) or cooling, heating & supply air (CH) configurations. • Available as diffuser shell (no coil/piping). • Accessories include rubber lip seal.

• Standard finish is RAL 9010 white paint on diffuser face. • Diffuser is designed to be recessed into a sidewall, soffit or bulkhead.

DESCRIPTION

INSTALLATION

The DISA-V sidewall active chilled beam diffuser was developed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings.

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that DISA-V chilled beams are connected to the supply air duct system which controls the supplied primary air volume. When integrated with room controllers, the units can be used both for single room and zone control.

In the primary distribution channel, CNC formed nozzles are precisely arranged. The number and size of nozzles (A, B, C, D) can be varied, thus allowing optimum adjustment of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced. The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced through a vertically mounted heat exchanger, to address sensible loads in the space. The primary air is mixed with the cooled secondary air and supplied to the room in a horizontal throw pattern through 1-slot diffuser integrated into the unit design.

DISA-V

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • The size of the supply duct system is minimized due to reduced primary air requirements. • Substantial reduction in the operating costs due to low primary air volume. • Improved thermal comfort inside the space. • Individual adjustment of the primary air volume by means of the nozzle configuration A, B, C, & D. • Suitable for all standard ceiling grids.

DISA-V

The DISA-V chilled beams are available in a multitude of configurations, resulting in produces that easily integrate into any building or design. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. The construction of the DISA-V product line is ideal for installation in soffits and sidewalls where ceiling space is limited. The horizontal throw pattern is enables comfortable cooling to be delivered to small spaces by effectively rolling without creating drafts.

SPECIFICATIONS

2.02 GENERAL

U42

A. It is the design intent of these specifications to provide a fully integrated HVAC system with all parts working together. These induction units need clean, dehumidified primary air from a dedicated outdoor air unit, hot and chilled water from a boiler and chiller, piping, and controls to coordinate each component to perform as intended. Changes, modifications, or substitutions on any component will impact all the other parts of the system and cannot be made without a careful review of all related specifications. B. Chilled beam unit shall be constant volume primary air flow units designed to induce a secondary airflow within the conditioned space using the primary conditioned air supply. Units shall be designed for ceiling installation with factory supplied hanging brackets. Hanger rods or other approved hanging system to be field supplied and installed in the field by installing contractor. C. Units shall be equipped with a round low velocity pres-

sure inlet transition, one air plenum and air induction nozzle plate, a supply and return chilled water piping connection, one supply and return hot water piping connection, and one combination supply/return air grille for effective room air distribution. The grille shall be hinged and secured in place with tool-less safety fasteners to provide full access to the return air side of the coil. The unit shall be capable of inducing the secondary airflow within the conditioned space using the velocity pressure of the primary airflow. This secondary air must flow directly from the room to the unit and shall not use the ceiling as a return air plenum. Active beam units using the ceiling plenum as a return air path are not acceptable. D. Each unit shall be equipped with a multiple row water coil for chilled water and hot water. Latent conditioning of the air supplied to the space shall be performed at the dedicated outdoor air unit and controlled by exhaust air humidity sensors.

2.03 CASINGS

A. The entire unit shall be constructed of 20 gauge galvanized G90 sheet metal. The primary air plenum and nozzles shall be designed and configured to provide uniform air distribution with low noise operation to all nozzles.

2.04 WATER COIL ASSEMBLY

A. Coils shall be of the hot and chilled water type utilizing aluminum fins and copper tubes with integral manual air vent. Coils shall be factory leak tested at 350 PSI water. Coil connections shall be as indicated on the drawings. B. Coils must be one flat plate assembly with no interconnecting joints to minimize leakage. Each coil shall be of the fin plate design surrounding the copper tube wall via fin spacing of 10 fins per inch.

2.05 PERFORMANCE

A. All chilled beam units shall be rated in accordance with EN 15116.

DESCRIPTION

INSTALLATION

The LCBS 1-way active chilled beam diffusers are designed for removing high thermal loads from the space. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings.

In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that LCBS units are connected to the supply air duct system delivering a constant volume of primary air to maintain optimum induction. When integrated with room controllers, the units can be used both for single room and zone control.

In the primary distribution channel, high density polyethylene injection molded nozzles are precisely arranged. There are three available nozzle sizes allowing optimum selection of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced.

The LCBS chilled beams are highly configurable, making them the perfect solution for all applications. These products have been designed to address heating and cooling loads in the space, with either a 2-pipe or 4-pipe system. LCBS units are supplied with a dew-point safety pan and are available with optional safety overflow switches.

CLEANING OF THE GRILLE/COIL To clean the grille and the coil, locate spring loaded retaining pins. Slide diffuser face towards spring retainers until pins on opposite side clear the unit frame. Diffuser face will now be able to swing down for removal. Do not use any scouring agents for cleaning these components; damage to the unit construction materials (galvanized steel, aluminum and copper) and the surface coatings (paint and anodized surfaces) may occur. After completion of maintenance, grille must be returned to its original operating position.

LCBS

The primary air, supplied by the air distribution system is supplied to the mixing chamber via induction nozzles. In the mixing chamber, room air is induced over a vertically mounted heat exchanger, to address sensible loads in the space. The vertical orientation of the coil allows for induction through all sides of the water coil. The primary air is mixed with the cooled secondary air and distributed in to the room through a 1-way multiple louver diffuser supplied with the unit.

• TCM2 is a modular active chilled beam diffuser with 4-way air distribution. TCM2

• Diffuser face on 48” x 48” unit is shipped loose for field mounting. The 24” x 24” unit ships complete.

• Supply/Return diffuser removable with out tools; providing access to interior of unit.

• Factory supplied hanging brackets.

• Accessories include disposable or washable filter, and plenum rated float switch for drain pan.

• Casing constructed of 20 GA galvanized steel. • Closed cell, anti-microbial poly foam insulation.

• Standard finish is #26 white paint on diffuser face.

DESCRIPTION The TCM2 4-way active chilled beam diffusers are designed for removing high thermal loads from the space. This model was designed specifically to meet the unique requirements of high population density spaces; depending on the unit size, the TCM2 can handle between 60 and 475 CFM of ventilation (primary) air. Supplied with tempered and dehumidified primary air, to handle the latent load, the beam addresses the remaining loads in the space with a heat exchanger installed in the unit. Decoupling the latent and sensible loads takes advantage of the superior volumetric heat capacity of water. The reduced the volume of air that must be delivered to the space results in reducing air handler capacity and size, smaller duct sizes, and overall energy savings. In the primary distribution channel, high density polyethylene injection molded nozzles are precisely arranged. There are three available nozzle sizes allowing optimum selection of the primary supply air volume. By reducing the primary air to meet the minimum requirements for either room ventilation or latent load in the space, total system energy costs are reduced.

The TCM2 chilled beams are highly configurable, making them the perfect solution for all applications. These products have been designed to address heating and cooling loads in

the space, with either a 2-pipe or 4-pipe system. TCM2 units are supplied with a dew-point safety pan and are available with optional safety overflow switches.

INSTALLATION In order to achieve a uniform cooling capacity, the beams should be connected to the cold water distribution system in parallel. It is recommended that TCM2 chilled beams are connected to the supply air duct system delivering a constant volume of primary air to maintain optimum induction. When integrated with room controllers, the units can be used both for single room and zone control.

ADVANTAGES • Removal of high thermal loads is possible in this air/water system. • Designed to accommodate the ventilation requirements of high population density areas. • The size of the supply duct system is minimized, due to reduced primary air requirements. • Substantial reduction in the operating costs, due to low primary air volume. • Improved thermal comfort inside the space. • Individual adjustment of the primary air volume by means of the nozzle size. • Suitable for all standard ceiling grids.

Chilled Beam

• SPB is a linear passive chilled beam diffuser.

SPB

• Unique design accommodates both recessed and exposed mounting. • Available in 2-pipe configuration. • Available as diffuser shell (no coil/piping). • Standard finish is RAL 9010 white paint on diffuser face.

DESCRIPTION Passive chilled beams are primarily used to provide comfortable sensible cooling, and can be used in many heating applications as well. The primary mode of heat transfer is by convection, with a percentage of heat transfer transmitted through radiation. During cooling, warm room air rises to the ceiling area; cool air around the coil sinks down to the occupied area as a result of the higher density. As the cool air descends in to the space, more warm air is drawn over the coil creating a convective current that drives the system. The exposed face of the passive beam is constructed from either painted perforated stainless steel, or a linear bar grille. The cooling strips are available in lengths of 4 feet to 14 feet in intervals of 2 feet. The beams are designed for integration into a suspension ceiling or for exposed mounting, suspended below the ceiling surface.

ADVANTAGES • SPB models designed to accommodate recessed or exposed installation with a single model. • Easy cleaning of the water coil and the housing. • Quick and simple installation. • Provide comfortable, effective heating and cooling to the space.

The diagram shows the approximate cooling capacity Pc in BTUH at a water flow rate of 0.8 gpm and a temperature difference between room air and the average water temperature of 14.5° F.

MOUNTING INFORMATION Mounting brackets that can slide along the longitudinal axis are mounted on the beam, 2 per beam. Alternatively, mounting shackles can be provided with are fastened to the beam and rest on the T-shaped support profiles of the false ceiling having a center-to-center distance of 600 mm. This reduces the mounting time as well as the mounting costs. The number of shackles required per beam, depending on length, is noted in the table below. Beam Length

PERFORMANCE DATA Criteria/design conditions: Max. length of strip - 14 feet Required cooling capacity - 2400 BTUH Room air temperature - 75BF Entering water temperature - 57BF Leaving water temperature - 61BF

A correction must be made to the beam performance based on the diagram below to adjust for water flow rates other than 0.8 gpm is K = Pc1.3 vs Pc0.8 = 1.04. Thus, due the higher amount of water, the actual capacity is 4% higher than the value shown in the diagram. Pc = 1.04 x 215 = 224 BTUH/ft. Required effective length (coil length) Leff = 2400/223 = 10.8ft.

Solution: Mean coil temperature = (57+61)/2 = 59BF Difference between room air temperature and mean coil temperature Dt = 75-59 = 16BF. According to the diagram below, the cooling capacity, PC0.8 for the 17-inch wide beam at a water flow rate of 0.8 gpm is 215 BTUH/ft. (BTU/Hr.ft)

Minimum unit length = 10.8ft + .3ft = 11.1ft. The next larger beam length, of 12 feet will be required to provide the required cooling in the space.

• FKL and HKL are architectural radiant ceiling products.

• Supplied with mounting equipment for fixed on site installation. • Available with hinged mounting equipment allowing sails to swing down up to 45B.

• 15mm diameter pipe connections.

DESCRIPTION The Alpety radiant ceiling systems are water driven radiation systems whose advantages include silent cooling, low energy consumption, and create a high degree of thermal comfort through draft free cooling and even temperature distribution in the space. However, it must be taken into account that these systems must be supported by additional mechanical ventilation and means to address the latent cooling requirements of the space.

ADVANTAGES • Radiant heat transfer increases occupancy comfort. • Reduces energy consumption by utilizing heat transfer capacity of water. • Minimize airflow and noise in the space. • Quick and simple installation. • Several models integrate seamlessly in to any architecture.

ALPETY (FKL, HKL)

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. In contrast, the ambient air heated by heat sources located in the room will rise. This gives rise to convection currents with very low flow velocities. Furthermore, the ceiling emits cooling and heating to the surrounding surfaces in the area by radiation. When radiation reaches one of these surfaces, the radiant energy is absorbed by that surface. The radiant heat transfer from the panels to surfaces and/or occupants in the room will occur regardless of the ambient air temperature. Radiant heat transfer results in high thermal comfort and leads to the ambient temperature feeling cooler than it actually is during cooling and warmer in heating. Depending on the percentage of the active ceiling surface to the overall surface of the room (including floor, walls, windows, furniture, etc.) the temperature perceived by the occupant will be 2.5 to 5 degrees cooler/warmer than it actually is. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

In conjunction with the customer’s own metal or acoustic ceiling tiles, the Alpety ceiling elements can be integrated in the room to create the ceiling façade, models FKL and HKL, or in combination with suspended ceiling systems with SKS models. The individual ceiling elements are usually joined to one another using flexible hoses. Connections can also be made using hard copper piping and soft soldering.

Radiant Ceiling Panels ALPETY (FKL, HKL)

Since the sensible cooling no longer has to be introduced into the room along with ventilation air, the volume of air supplied can be reduced to the meet the fresh air requirements. By reducing the volume of air supplied the possibility of drafts and noise levels are greatly reduced. This leads to increased occupancy comfort. Addressing thermal loads using the Alpety products makes use of the increased heat transfer capacities of water, as compared to air, increasing overall system efficiency.

ALPETY SKS

Radiant ceilings systems emit heating and cooling by both convection and radiation. During cooling, ambient air near the ceiling cools and falls to the occupied area, due to its higher density. In contrast, the ambient air heated by heat sources located in the room will rise. This gives rise to convection currents with very low flow velocities. Furthermore, the ceiling emits cooling and heating to the surrounding surfaces in the area by radiation. When radiation reaches one of these surfaces, the radiant energy is absorbed by that surface. The radiant heat transfer from the panels to surfaces and/or occupants in the room will occur regardless of the ambient air temperature. Radiant heat transfer results in high thermal comfort and leads to the ambient temperature feeling cooler than it actually is during cooling and warmer in heating. Depending on the percentage of the active ceiling surface to the overall surface of the room (including floor, walls, windows, furniture, etc.) the temperature perceived by the occupant will be 2.5 to 5 degrees cooler/warmer than it actually is. This effect has the advantage that the room requires less conditioning than a traditional system, introducing an additional opportunity for energy savings.

• Standard finish is RAL 9010 white powder coating.

Energy Solutions

The modulated valve actuator control device increases Chiller and Boiler efficiency by 15-20% with substantial energy savings by meeting exact conditioned space load requirements. The overall net effect of modulated control valves adjusting the water flow rate to meet occupied space load requirements as they change, is increased occupant comfort in the conditioned space while reducing system energy costs.

One of the easiest ways to save energy and money is to upgrade to a programmable thermostat. These thermostats allow the fan coil unit to be programmed to run only at specific times of the day at specific temperatures. Programming the thermostat to shut down or reduce the cooling/heating demands during periods of time when the occupant is typically away will quickly begin reducing costs after installation. The occupant can always temporary override the program during these times if necessary.

www.titus-hvac.com | www.titus-energysolutions.com

Most ECM motors currently in the market have a 70% motor efficiency at full and partial loads which substantially reduces Energy costs. The ECM motor also has the ability to modulate the airflow to meet partial load requirements thereby further reducing the energy requirements of a building. The low operating temperature of the ECM motor also requires very little energy to offset the heat gain from the motor to the cooled airstream, thus also reducing the building energy requirements.

An alternative to improving the efficiency and energy consumption of the fan coil unit is to install a programmable thermostat with occupancy sensors or a keycard. The thermostat can be programmed to gradually reduce the cooling/ heating demand to a pre-specified point if an occupant is not present. By using these sensors in conjunction with a programmable thermostat, tighter control of the energy consumption of a fan coil unit can be maintained.

An alternative to improving the efficiency and energy consumption of the fan coil unit is to install a programmable thermostat with a motion sensor. The thermostat can be programmed to gradually reduce the cooling/heating demand to a prespecified point if an occupant is not present. By using this wireless motion sensor in conjunction with a programmable thermostat, tighter control of the energy consumption of a fan coil unit can be maintained.
