I. EXECUTIVE SUMMARY

This report covers the examination of the mold issue that has plagued the House of Justice as it relates to the air-conditioning system in place. A four-day survey was conducted from 29th of January to 1st of February 1, 2018. The survey covered a visual inspection to the facility, interviewing of building personnel in familiar with maintenance and operation of the air conditioning system in place, installing data loggers through the facility and equipment to record dry bulb temperature and relative humidity reading while the building was in use and when the building was unoccupied. Data was also collected on the air flow at the various zones, measuring the air flows of ceiling diffusers and registers for supply air, return air, and exhaust air. Data was used to analyze the dynamics of the air conditioning in place and how it affects the mold issues in the building.

What was found in the data and information gathered data shows that the building indoor condition promotes the growth of mold spores and colonize in surfaces. The mold and mildew within the building are evident by the musty smell throughout the facility It was most likely caused by water leaks from a various incident that happens in the building over the years During the inspection, there were only a few visible signs of mold on books, furniture, judge’s robe, and ceiling tiles, but none within the air handling units (AHU’s) and within the ductwork. The musty smell appears to be generated by materials that remained after the water leak events and not properly remediated to prevent the potential of mold growth such as carpet, furniture, ceiling tiles, gypsum board walls, furniture, books, papers, etc.

The air conditioning system does play a part in the continued problem of the musty smell by its inability to properly control the relative humidity within the various zones. Because of the changes in the uses of spaces throughout the building, the cooling load requirements have changed significantly, and the existing units are overcooled causing the room temperature requirements to be met quickly and not allowing enough time for the dehumidification process to occur thus causing wet-cold air. Additionally, there is very poor indoor air quality within the building. Most of the outdoor air dampers at the AHU’s were shut and inoperable. Also, almost all the exhaust fans were not working. This leaves the musty smelly air to re-circulate within the building with little means of escape.

Except for an ARRA funded chiller replacement in 2008 which installed new chiller, remote condenser and pump, most of the air conditioning system is old and antiquated with most equipment being what was originally installed when the building was open in 1997. Two of the existing chillers are still utilizing the R-22 refrigerant scheduled to be phased out in 2020. It is recommended to remove and replace older equipment and upgrade the system more appropriate to the current use of the building while improving the indoor air quality of the building.

II. GENERAL

WM Engineering Services, LLC (WMES) was tasked to provide mechanical consultation services to assess mold and high humidity throughout Guma’ Hustisia, Iimwal Aweewe, House of Justice Building located in the village of Susupe, Saipan, Commonwealth of the Northern Mariana Islands (CNMI) that may be caused by the existing air-conditioning system in place. The assessment shall focus on the air-conditioning system components including all associated equipment, piping, and controls. The intent of this project is to assess the current condition of the air-conditioning system that may be contributing to the high humidity conditions and mold, develop a concept design for the scope of work for the corrective repairs to the air-conditioning and ventilation system. The existing building is a concrete structure constructed in 1997 consisting of a basement, ground floor, and second floor, and houses the Supreme Court, 5 Superior Courtrooms, Justice and Judges Chambers, as well as supporting offices, library, and utility areas totaling to 32,637 square feet. Based on the construction documents provided, the airconditioning system in place is an air-cooled chilled water system which distributes chilled water at a constant volume to various air handling units and fan coil units. The air handling units and fan coil units are constant volume ducted systems which deliver cool air to the various cooling zones within the building. The controls for the air conditioning system are all local to the equipment and are stand alone. There is no central building automation system that controls or monitors the chiller plant, pumps, air handling units, fan coil units and exhaust fans.

WM Engineering Services conducted kick-off meeting on January 29, 2018, at 09:00 with the stakeholders involved with the maintenance and operation of the existing system to discuss the project concerns, challenges, goals, and expectations. WM Engineering Services then proceeded with a field survey immediately after the meeting. The survey was conducted from January 29 to February 1, 2018, on the existing air-conditioning system in place at the Judiciary Building. The survey included the verification of as-built conditions of the air conditioning systems in place by:

• taking photos to document of the facility

• record existing air flow at the registers throughout the building

• record temperatures, and relative humidity of various spaces

• confirm the operation and performance of air conditioning and ventilation equipment

• visually identify areas of suspicious mold growth and high humidity.

It should be noted that this investigation will not involve any breaking of walls, floors, and ceilings and will be limited to areas readily accessible and visible including access panels available. It should be noted that mold remediation and humidity solutions may extend beyond just the air-conditioning and ventilation system and may also include other disciplines such as architectural, industrial hygienist, and electrical engineering disciplines which are not part of this contract Our proposal excludes such architectural, industrial hygienist, mold spore evaluation, and engineering services.

III. FINDINGS

Since the facility was first built and occupied in 1997, there has been no significant changes recorded to the air conditioning system except for the “addition” of an ARRA funded 200 TON Smardt Chiller in 2008-2009 that included a new air-cooled condenser and chilled water pump. According to the building staff the building has been experiencing elevated relative humidity and mold issue over the past 10 years. Over the years there have been several changes of Building Superintendents supervising the facility. With the change of personnel, there appears to be a poor turnover of record keeping of the building’s maintenance records. Presently there are no available maintenance records or OperatingMaintenance manuals for the existing equipment. The current Building Superintendent stated there is no current preventative maintenance program in place for the air conditioning and ventilation system due to funding issues and the repairs and maintenance are on an on-call basis as required. On the kick-off meeting, it has been discussed the event of major water damage from a pipe bursting where the lower floor was flooded with kneedeep water in early 2000, but the remediation and repairs to the building appear undocumented. There has also been water infiltration damage from the Soudelor Typhoon. There is a contract in place to re-seal the windows which are continuing to leak wind-driven rain into the building. There is also an on-going contract to replace all carpet in the facility with laminate vinyl floor tiles.

It was found that there were several undocumented changes in room partitioning and changes in room use which differs from the construction document plans on record. A lot of designated offices have become the storage room for files, and other miscellaneous office supplies and furniture. Another major change to the building was the enclosure of the public lobby of the House of Justice building and the addition of a large package air conditioning unit, although the unit is not currently in operation. This area was originally designed as an open-air area with natural ventilation. Another significant change in use is the Library which currently used for offices, assembly, and file storage.

The water side of the HVAC system consists of two (2) 100-TON air cooled chillers, one (1) 200-TON Smardt chiller and three remote air-cooled condensers. The current system operates with the Smart DT chiller operating as the primary chiller in operation with the

two TRANE chillers as back-up. The Smart DT chiller utilizes R134a refrigerant and the TRANE chillers both are R-22 type refrigerant. During the survey, the Smart DT Chiller was down for repairs and the two TRANE chillers were operating but only at 50% each due to compressor or refrigerant circuit issues on each chiller. The existing remote aircooled condensers were on the roof but were not accessed. The current leaving chilled water temperature conditions at 52 degrees F and returning at 56 degrees F, See appendix photo 1.0

Based on existing plans the chilled water pump is end-suction pumps rate at 240 gallons per minute (GPM), 120 feet total dynamic head pressure, and 25 horsepower. Currently, the newly installed chilled water pump number three (3) is down for repairs. Pump gages are not calibrated or broken so pump pressures could not be confirmed. The remaining 2 older pumps appear to be in fair condition, and the pump base and foundation are in fair condition. Originally the chilled water pumps were interlocked to operate with its associated chiller but appear to be manually operated. The indoor chilled water piping and insulation remained intact. Chilled water components are in fair conditions, but the surface of piping showed signs of corrosion, see photo 1.1.

Due to Scope of work, there was no testing of the valve and inspecting inside section of each component. More so, the underground chilled water pipe is not assessed. There is a suspected water leak in the chilled water piping system which requires the make-up water tank to be filled every 3 days according to maintenance sub-contractor JWS.

The air side of HVAC system consists of chilled water type Air Handling unit and Fan Coil units which distributes air into the various rooms within its respective zone via an insulated steel duct system. There are 16 large AHU ranging in capacity of 10 TON to 25 TONS of cooling. The smaller FCU consist of 8 units and range from 1 TON to 2.5 TONS of cooling. The AHU’s are single zoned, constant volume unit and have a mixing-filter box with washable filter. There was originally motorize dampers on the outside air and return duct, but they are not operational. The original automated controls have been disabled and the AHU’s are being controlled locally by a temperature sensor in the main return duct within the mechanical room and a thermostat controller on the mechanical room wall. There is also a timer installed within the mechanical room but was disabled for the most part. There is also a large TRANE package type unit, independent of the chilled water

system, located on the supreme court roof and intended to cool the main entry but the capacity could not be confirmed because it is missing the nameplate data. This unit is currently not operational, and it is not known if it is still functional. The Building Superintendent stated it was not in use to reduce electric cost. There is a standalone direct expansion unit located in the ADR/Conference room area. A separate split type unit in the IT room that supplements the existing air supply near the former storage/workroom. There are three (3) 120-pint Honeywell dehumidifier was added and installed in the return duct of AHU 8, 14, and 15 that are in constant operation, but there are no plans or other design documents recording what was installed or how it was installed. The installing contractor JWS did mention that the dehumidifiers are always in operation, but it was not clear how it’s operation coincides with the operation of the AHU’s.

Main Entry (Package Unit)

The AHU # 2 filter and filter rack were severely damaged due to corrosion, see photo 2.8. The AHU that serve the Superior Courts 202, 205, 217, 220 and 223 each has outside air damper that was shut closed and corrosion damage is present on each damper’s louver, see photo 2.9. The AHU # 3, 7, 9, 11 and 12 are installed with new outside air Manual volume damper and was also close The old actuator motor and its wiring are left inside the Mechanical Room, see photo 3.7. The AHU # 10 is installed above the ceiling of Evidence Room at Marshals Office. Unit’s Power and control wiring are pulled out of its connection. Smaller FCU was not visually surveyed because they were primarily recirculation of air within small spaces. Ductwork within the mechanical room appeared to be in fair condition except for the outside air ducts and some mixing boxes which were corroded and inoperable. Accumulation of dust and dirt are present at diffuser face and at intake louvers.

See photo 5.1.

The only air circulation comes from the people traffic which comes mostly in the main entry for the public and the employee traffic in the back entry. This allows untreated warm humid air to enter the building without being treated. There are several exhaust fans and ventilators throughout the facility and most are not operational. Many of the exhaust registers are cover with dust. The controls appear to be either manual controls or interlocked with the light switch.

IV. ANALYSIS

There was a strong musty smell within the air-conditioned areas which is a sign of an environment that promotes mold and mildew. Mold and mildew usually can be found in building components (duct insulation, gypsum board, ceiling tiles wood, etc.), furniture, papers, and carpet floor covering where water is absorbed readily. The usual cause would be water damage from water leaks from piping or water infiltration into the building from wind-driven rain such as a storm or typhoon or even structural cracks on the roof or

improperly sealed pipe, or duct penetrations through the walls or roof. Once the mold and mildew have occurred within the building, the best way to remediate is to remove the affected areas and maintain a dry environment. Because there has been recorded major water damage from a pipe leak and continues to have water leaks around the window, the presence of the mold and mildew will persist until physically removed from the premises. Disinfecting and cleaning of affected areas can remove on the surface but will not remove mold and mildew deep inside the material. The planned removal of the carpet and the repairs to the leaky window are a good way of reducing the sources of moisture that promote the growth of mold and mildew in the building. It is strongly recommended to dispose of all clothing in one of Justice’s wardrobe closet, furniture, books, and papers where mold is visible, see photo 5.6. There were only a few areas where building components had visible mold and mildew. No visible mold on the surface of walls and partitions. Some were found on ceiling tiles such as in Jury Room C, but they appear to be water leaks from the structure Many ceiling tiles on the first floor and second were sagging and could be an indication of high water content in the material, thus ceiling tiles should be replaced, see photo 5.2. There was no evidence of mold and mildew within the cooling coils, air filters, fans, or inside the ducts. It is highly recommended that the air distribution ductwork, air handling units, fan coil units, and diffusers/registers be professionally cleaned. Also, install more efficient disposable MERV 13 filters in the AHU’s and FCU’s to reduce the dust in the building. The fungus is more likely to grow whenever the environment suited them. A spore (seed), a viable source of food, adequate moisture in the food source and acceptable temperature are the four (4) elements that molds needed to grow. Over the years, the building where exposed to several types of water damage. Without a proper water removal or drying, moisture remains entrapped in the surfaces. Introducing cool-dry fresh air into the space help help lower the humidity level in the space. With the lack of fresh air due to the closed fresh air intake dampers and the broken exhaust fans, the musty air is only circulating within the space through the air handling units The only air that may exfiltrate or leaves the building is from people moving into and out of the building through the main entry, back entry, delivery areas, and other less used exit doors.

The AHU’s airflow has a noticeable drop in performance. Based on airflow taken at the registers and diffusers during the survey (see Appendix C-3), the air flow has been reduced from 19-43% of the original design parameters creating even more poor air circulation. The data collected from the survey showed that there was unusually high relative humidity over the entire building, except for the ADR/Conference room area and the server IT area which has its own air conditioning system and is independent of the chilled water system. ASHRAE standards for room dry bulb temperature and relative humidity for human comfort set the ranges at 75-78 degrees Fahrenheit (F) for summer conditions and relative humidity (RH) in a room from 40-60%. The existing rooms served by the chilled water system have room dry bulb temperatures of 68-72 degrees F and RH in the range of 6588% (see Appendix C-5). Currently, the thermostat is set at 68 degrees F and the almost time the timers have been disabled, thus allowing the unit to run continuously. This includes the AHU with dehumidifiers installed in the units. Also, interesting to note that despite the diminished capacity of the chilled water system and the air handling units, the space temperature remained colder than what is expected. It was usual to see some people have small floor mounted space heaters near their desk (see photo 5.8). An analysis was performed on the cooling load requirements based on the current use of the building (see Appendix D). Because of the many changes of room uses, such as converting an office to a storage area, or converting the library to an assembly room/storage/IT/office requires a much different cooling capacity. From the table below, it can be seen that the current load is up to 87% less than the original cooling requirement.

Table 1.2 Comparison of Existing AHU cooling capacity and cooling load based on current use

The design has a change of temperature of the entering and leaving temperature 10 degrees F with water entering at 45 degrees F. This should create a drop on air temperature across the cooling coils of 15-20 degrees F. Currently the existing temperature entering and leaving the coil is only 4 degrees F and the temperature drop across the cooling coils are only 1 to 3 degrees F. The elevated entering chilled water temperature at 52 degrees F reduces the AHU to reduce temperature and lower the relative humidity in the room. When the AHU’s capacity is oversized for space, the temperature can be met quickly and not allowing moisture in the air to condensate at the cooling coil. The psychometric process of air conditioning cycle is to cool and dehumidify the air as it reacts to meeting the thermostat setpoint.

The age of the equipment, the current repairs, and the refrigerant it uses, it is recommended to replace the older TRANE chillers, remote air-cooled condensers, and associated chilled water pumps. The older TRANE units are using R-22 refrigerant which had stop production in 2010 and is scheduled to be phaseout by 2020. Also, it is recommended to replace the existing AHU’s and FCU’s and its associated piping and controls because it is also at its end of useful life and it is oversized for the zones it serves. By replacing the existing AHU’s with more appropriate size units, the system will be able to control the

temperature, as well as, the relative humidity better in the occupied spaces. As an option, ACCU thermo-fusers VAV diffusers (see appendix G) can better control air flow into the space based on the demand for cooling by varying the amount of airflow into the space. This can reduce the energy cost of operating the air conditioning unit by reducing the fan speed during the time of low occupancy. Typically, a building would introduce outdoor requirements of a building into the AHU’s to allow the air to be pretreated before entering the building. Other outdoor air may enter the building untreated through people traffic at entry doors and infiltrate through small gaps around fenestrations in the building construction. The lack of fresh air into the AHU’s creates poor indoor air quality. Outdoor and exhaust air is required per the International Mechanical Code and ASHRAE 62.1 standard. The normal building design would keep the building under slight positive pressure by providing at most 10% more make-up air than exhaust air. Since the exhaust fans are mostly not working and the outside air dampers in the AHU’s are closed there is currently no mechanical means from the system that generates the code required fresh air and exhaust air flow rates. There is a lot of infiltration and exfiltration from the people traffic in the Main Entry where the public enters and the Back Entry where the employees enter and exit. Because the Main Entry air-conditioner is not in operation and the back entry not having any air conditioning because AHU #10 is not operational, the building’s exit and entry points are under neutral building pressure allowing untreated warm, humid outside air to enter the building thus attributing to the high humidity conditions

It is recommended to re-introduce an air conditioning system at the Main Entry, using dedicated outdoor air units to provide the required make-up air plus 10% above the required exhaust air to pressurize the building and minimize the amount of infiltration of the untreated humid outside air into the building to reduce the buildings high relative humidity. Additional, a vestibule can be added to the main entrance where the most people traffic occurs to further reduce the amount of warm outdoor air infiltrating into the building It is also recommended to incorporate a ventilation demand system into the AHU’s where occupant load varies greatly over the day. A ventilation demand system will modulate the amount of outside air in the space by using carbon dioxide (CO2) sensors to detect occupant load based on the CO2 level in the room and modulate a motorized damper in the outside

air ducts. This system will reduce energy cost by minimizing the amount of outside air when the zones have low occupancy. Further, it is recommended to incorporate an odor control GPS system (see appendix G) into all AHU’s and FCU’s to control the musty smell. There is no preventative maintenance plan in place for the upkeep of the air conditioning and ventilation system. It is highly recommended to incorporate a preventative maintenance plan to ensure the system is functioning optimally and to guard against major breakdowns in the system. A central building automation system is also a good tool to centrally monitor the equipment’s operation that is remotely located on the roof and is hard to access. The central monitoring station can be located in the Buildings Superintendent Office and/or maintenance service provider.

Performance Climate Changer

Custom Performance Climate Changer

Simplifying the complex

Highest standards

Trane incorporates superior construction methods to deliver the industry’s highest reliability standards and lowest leakage rates meeting ASHRAE 111 Class 6 or better for maximum energy savings and lower operating costs. You can choose double-walled casing panels up to 4 inches thick and injected with high-performance foam insulation to reduce air leakage and deflection, resulting in maximized energy efficiency and minimized utility costs. Our no-through-metal casing, including fasteners, minimizes thermal transmission and prevents condensation. Optional fan arrays allow up to 100 percent redundancy and deliver up to 10 percent increased efficiency.

Predictable performance

When designing a custom air-handling system, we ensure reliability and accuracy by providing lab-tested data through our prediction tools for leakage, deflection, acoustics and thermal performance. It’s the surest way to deliver the most value for your building.

Trane is the only manufacturer to provide verified and guaranteed moisture carryover data to customers, validating that there is no moisture carryover even at face velocity over 500 feet per minute.

Validated performance for the air handler is available with options such as the following:

• Coils with high-efficient fin design optimized to the nearest fin-per-foot

• Coils with the best moisture carryover limits in the industry

• Direct-Drive Plenum (DDP) fans

• Energy recovery wheels

• Unit sound data based on AHRI 260 tests

• Cool Dry Quiet (CDQ™) desiccant dehumidification system

Direct-Drive

allow up to 100 percent redundancy for greater systems reliability and up to 10 percent increased efficiency.

• Trane Catalytic Air Cleaning System (TCACS)

Plenum (DDP) fan arrays

Factory tested

Testing and validating an air handler before it leaves the factory confirms that its actual performance matches what was predicted during the selection process to best support your needs. We invite you to witness the testing of your custom air handler unit at the factory. Contact your account manager for more information.

Ultra-quiet operations

Trane provides AHRI 260–tested acoustical performance.

And unlike other manufacturers, Trane measures the entire air handler unit not just individual components to ensure it operates at the quiet sound levels you require. Optional Trane Acoustics Program (TAP™) modeling software accurately predicts and compares system sound levels to ensure that you don’t have to over- or under-design your air handler to receive the acoustical performance you desire.

Factory-installed controls

Performance Climate Changer air handlers offer one of the most comprehensive factory-packaged, open protocol controls systems available. Controls are engineered, mounted, wired and tested in the factory. This reduces installation time and expense and ensures system consistency and reliability. Factory mounting also reduces the leakage problem that can occur when controls are installed on-site and eliminates the risk of damaging the custom casing.

Trane CDQ system

When dehumidification is required, a Trane CDQ system can be added to your Performance Climate Changer air handler unit to remove double or even triple the amount of moisture from the air as compared to traditional designs. CDQ technology is perfect for dry storage, hospital operating rooms, laboratories, schools and other building applications where maintaining low humidity levels is vital.

Advanced energy-recovery options

AHRI 1060–certified energy wheels recover energy from the exhaust air stream, transferring it to the air being distributed throughout a building and reducing the workload on chillers and boilers, lowering energy use and utility bills. Energy wheels are available in both indoor and outdoor arrangements, and can be applied in both a 100 percent outdoor air unit and a mixed air unit. Trane energy recovery software can model your specifications to show the benefit of payback analysis.

The patented Trane Dual Exhaust Energy Recover (DEER) system captures energy that would otherwise be lost by directing exhaust air from a building and its restrooms into a specifically designed energy wheel arrangement that recovers energy from multiple air streams while minimizing recirculation of toilet exhaust in a single unit with a more efficient fan and motor arrangement.

Air-to-air plate heat exchangers are a great solution to recover sensible energy (heat only) from an exhaust air stream, with little or no crosscontamination. These exchangers may also be used for free reheat in dehumidification applications, including dedicated outdoor air systems. Where exhaust air is not available, exchangers can be used in series to heat the dehumidified air.

Easy installation

The Performance FlexFit ™ solution ensures that your energy-efficient Trane air handler can be assembled on-site and commissioned to deliver the performance you want even in the most challenging spaces.

With the FlexFit solution, you receive fast delivery and assembly options that best meet your particular space requirements. Depending on your preference, it can arrive fully preassembled from the factory ready to be installed, or if space is an issue we can ship it disassembled with detailed instructions on how to assemble it on-site.

To simplify and expedite the process even further, you can elect to have a Trane representative on-site to oversee the assembly of the unit.

In addition to the FlexFit solution, Trane provides many installation options to support your scheduling needs.

The right people for the job

Art meets science in the Trane® Custom Performance Climate Changer™ air handler. We combine expertise and experience with a robust quality assurance process to provide you with the best and most reliable air handler to meet your specific needs.

CGAM air-cooled scroll chiller

Highly efficient, yet extremely quiet

The right balance of energy efficiency and quiet operation

High efficiency or low noise? Most air-cooled chillers require you to choose between the two. The new 20 to 130 ton model CGAM air-cooled scroll chiller from Trane gives you the best of both worlds.

A quieter fan often produces less air flow, making it less efficient. The Trane design team compiled the best approaches from around the globe to optimize the Trane CGAM chiller—so that it meets global green initiatives and ASHRAE energy-efficiency standards.

The Trane CGAM chiller is one of the quietest air-cooled chillers, even among screw compressor equipment. Low sound levels are standard, with a 5 to 8 decibel reduction compared to previous

Trane air-cooled chiller models. And with factoryinstalled attenuation, Trane reduces sound levels even further—up to an additional 3 decibels.

Reliability you can count on

You need performance you can count on. As a result, we extensively test on our compressors and units to confirm their robust design.

Trane delivers

• Extreme testing—including cold ambient starts, hot water starts and high ambient operation

• Compressor-accelerated lifecycle testing, including high-pressure ratio, high load test, flooded starts/stops, start/stop testing and phase reversal

• Performance modeling and verification, both during design and for the life of the chiller

• FEA analysis to confirm the unit structure can withstand shipping, rigging and operational activity

• Electrical testing with destructive testing for short circuit withstand rating

To minimize leaks, Trane improved the coil structure by strengthening the coil frame and changing the construction method.

We use a single copper tube for two passes through the coil to reduce braze joints on one side, eliminating up to sixty joints. This new construction method ensures all coils are square, so the coil components are better aligned.

The Trane on-site test facility ensures the reliability and performance of your system.

Factory-installed reliability

Several factory-installed features further reduce your energy consumption, add redundancy for mission-critical operations and reduce jobsite installation time—when every day counts.

A factory-installed pump package, designed specifically for this unit, comes pre-wired and factory-tested. The dual pump set-up provides built-in redundancy and the standard inverter delivers added energy savings.

With the factory-installed buffer tank, you can use the chiller in applications with less than a three-minute water loop and still maintain precise temperature control.

The flow switch and water strainer are also factory-installed as standard, reducing job site installation requirements and ensuring reliable operation.

Reduce your energy usage at every point

Using some of the best analytic approaches and tools in the industry, Trane engineers look for ways to reduce energy usage at every point within your system. For example, using partial heat recovery, the heat rejected from the condenser while cooling the building can be redirected through a factory-installed heat exchanger on the chiller to provide heat for VAV reheat coils. This can dehumidify a commercial building more efficiently, or pre-heat laundry or pool water in a hotel.

Another energy-saving strategy is a thermal storage system that uses ice made at night, when energy costs are lowest, to cool the building during the day. Thermal storage can be used in many settings, including schools, government buildings and industrial processes.

One way Trane reduces energy costs is with a thermal storage system design that uses ice made at night, when energy demand and cost are lowest, to cool the building during the day.

Durability—powder-coated components and optional coated coils minimize corrosion.

Serviceability—major components are positioned for easy access. The unit structure is designed to rig pump up for easy seal changes.

Controls for reliability, efficiency and system monitoring

Trane unit controls and building automation solutions are designed to meet your critical requirements. Adaptive Control™ algorithms embedded in the factory-mounted CH530 controller on the CGAM chiller use Trane proprietary strategies to respond to normal, extreme or adverse conditions. The sophisticated algorithms intelligently maximize uptime while protecting equipment from damage.

The chiller manages time-of-day scheduling for small buildings or schools without a building automation system. If an integrated pump package is included, the chiller even controls pumps as needed. For larger enterprise-wide projects, a Tracer ES™ building automation system monitors and manages all chillers within the enterprise.

Manage multiple chillers from any location

Adding the Tracer™ SC controller to a system provides a flexible, cost-effective solution for managing your HVAC system that can extend to lighting and energy consumption. Its simplified,

Web-based management tools help improve efficiencies, increase tenant comfort and reduce energy costs.

Accessible from any PC with an Internet connection, Tracer SC eliminates the need for a dedicated computer and monitor, so you can manage system performance whenever, wherever it is convenient. Tracer SC controller’s simplified, Web-based management tool reduces scheduling, reporting and applications programming chores to simple “point and click” tasks. Users do not have to invest in special software or training—so it is easy to control the building without additional costs.

Tracer SC is scalable for most buildings—small, medium or large—and can grow with your building and adapt to your changing needs. With expandable communications from 30- to 60- to 120-unit controllers, it is a flexible and costeffective choice.

Tracer SC now supports BACnet™ top to bottom, as well as existing LonWorks™ controllers.

Tracer SC can manage chiller sequencing and load sensing for optimum control on site or over the Web.

CUSTOMERS

Plasma has many benefits. GPS’ technology produces natural, friendly, oxidizers that seek out contaminants and odors in the space. The plasma, when produced and injected into a moving air stream, breaks down gases to harmless compounds prevalent in the atmosphere such as oxygen, nitrogen, water vapor and carbon dioxide. In addition to the reduction of gases and odors, plasma also reduces particulates and kills mold, bacteria and virus in the space.

GPS’ Plasma Reduces Airborne Particles

The plasma clusters are drawn to airborne particles by their electrical charge. Once the cluster is formed around the particle, the particle grows larger by attracting nearby particles and increases the filtration effectiveness.

Plasma Kills Virus, Bacteria and Mold - In the Space!

Plasma travels with the air flow and surrounds the pathogens (See Figure 1), confirmed by EMSL Labs. Next, the plasma robs the pathogens of the hydrogen necessary for them to survive (See Figure 2). During the final step, the plasma eliminates hydrogen from the pathogen and then the cleansing process is complete, making the airborne virus, bacteria or mold spore inactive (See Figure 3).

HIGH-EFFICIENCY AIR FILTERS

HERE’S A QUICK LOOK AT THE TYPES OF HIGH-EFFICIENCY AIR FILTERS AND HOW THEY ARE USED.

HIGH-EFFICIENCY PLEATED FILTERS

MERV ratings from 11-14.

These are the standard when it comes to most HVAC systems, because they are easy to install, come in standard sizes and have a low initial cost.

ADVANTAGE:

Energy Efficient and Environmentally Friendly

WHERE THEY ARE USED:

Commercial, healthcare, municipal, government, hospitality and residential

POCKET FILTERS

MERV ratings up to 14.

Also referred to as bag filters, pocket filters are constructed of a plastic or galvanized steel frame and contain fiberglass or synthetic media. They are called pocket filters because the media is stitched or sonically welded to form pockets ranging from 10 to 36 inches deep.

ADVANTAGE:

Long Service Life

WHERE THEY ARE USED:

Commercial, educational, healthcare, government and manufacturing

WHAT IS MERV?

RIGID CELL FILTERS

MERV ratings from 11-14.

These filters come in a box-style format and contain either synthetic media or fiberglass. Rigid cell filters look similar to pleated filters but have a depth of 6-12 inches and are surrounded by a galvanized metal or plastic frame.

ADVANTAGE:

Durability

WHERE THEY ARE USED:

Commercial and industrial HVAC systems, VAV systems, high-humidity applications, clean rooms, healthcare, food service and manufacturing

HEPA FILTERS

Not MERV rated because they must offer efficiency of at least 99.97% and up to 99.99% of airborne particles 0.3 microns in size to qualify as HEPA.

ADVANTAGE:

Highest Efficiency

WHERE THEY ARE USED: Clean rooms, medical facilities, laboratories, airplanes, commercial, industrial, residential

MERV stands for the Minimum Efficiency Reporting Value of a filter. It is a method of stating the efficiency of a filter based on particle size and is determined by testing the performance of the filter when exposed to particles of a known size in the air stream.

MERV can be used as a guide to selecting filters for specific contaminants within a range of particle sizes.

Control These Contaminants: 1.0-3.0 Micron Particle Size Legionella, Lead Dust, Humidifier Dust, Coal Dust, Nebulizer Dust

Applications:

Control These Contaminants:

<_0.30 Micron Particle Size Virus (Unattached), Carbon Dust, Sea Salt, All Combustion Smoke, Radon Progeny

Applications: Hospital Patient Care, General Surgery, Smoking Lounges, Superior Commercial Buildings 17-20

Applications: Cleanrooms, Radioactive Materials, Carcinogenic Materials, Pharmaceutical Manufacturing, Orthopedic Surgery

TF Therma-Fuser™

SquareThermally Powered VAV Diffuser

Models: TF-HC Separate set points for VAV heating and VAV cooling

TF-HC-LH A TF-HC with maximum flow limited in heating only

TF-CW One set point for VAV cooling with warm up

TF-C One set point for VAV cooling only

BENEFITS AT A GLANCE.

INDIVIDUAL COMFORT SELECTION AND CONTROL

Every Therma-Fuser™ diffuser is a VAV zone of temperature control providing pleasing comfort in both heating and cooling. The built in thermostat senses average room air temperature from a sample of air induced into the unit. It controls air flow to precisely match the comfort requirements of the room or portion of the room served. Occupants breathe easier knowing that their personal temperature choice will not be changed by someone else.

LIMITED HEAT & NO HEAT

The ASHRAE Standard 90.1 requires controls in an HVAC system that limit the reheating of air that was previously cooled. Use the LIMITED HEAT option to meet the ASHRAE standard.

The TF-LIMITED HEAT has an adjustable mechanical stop that will limit maximum flow to the required percentage only in the heating mode.

For applications, such as a computer room, where cooling loads always exist but the supply may at times be heated, there is a NO HEAT option. When the supply air is warm, the TF-NO HEAT will close and not open regardless of the room temperature.

ONLY THERMA-FUSER™ VAV OFFERS THESE BENEFITS

• Separate temperature set points for VAV heating and VAV cooling.

• Superior air distribution— longer throws, no dumping, more entrainment, even temperature distribution, higher ADPI* and better room air change effectiveness.

• Lowest cost per zone of control.

• Lowest energy VAV terminal— green VAV.

• Low to no maintenance— 10 year warranty.

• Easily adapts to office changes.

HOW IT WORKS

Model TF Therma-Fuser diffusers are 24” (600mm) square ceiling diffusers with built in temperature controls and VAV damper. Four blade dampers move up to close and down to open, metering air flow (warm or cool) into the room in response to room temperature. The dampers are mechanically positioned by thermostat/actuators which are both a room thermostat and damper motor. The room thermostat/actuators are a large brass cylinder containing a petroleum based wax. The wax melts and expands when heated, driving a piston out. A spring retracts the piston when the wax cools and contracts. The movement of the piston positions the dampers in a proportional manner.

ROOM AIR SENSING

As with all diffusers, air circulates around the room in a circular motion. Secondary air rises under the diffuser, passes beneath the appearance panel and entrains with the primary air at the outside edge of the diffuser (fig.1). This secondary air best represents average room temperature.

To monitor average room temperature, a continuous sample of secondary air is drawn around the appearance panel past the room thermostats. This is accomplished by feeding primary air through four venturi nozzles. Primary air blowing through the nozzles creates just enough vacuum to draw some secondary air around the appearance panel, over the thermostats and out the other side. A properly applied TF will hold the room average within 1.5˚F/0.9˚C of the temperature selected.

COOLING MODE

In the cooling mode the dampers open on a rise in room temperature. As the room warms, the wax in the room thermostats melts and expands. This pushes the cooling thermostat piston outward against the control plate. The control plate then pivots around the center bearing, opening the dampers allowing more supply air to enter the room. When the room cools, the wax contracts, a spring retracts the cooling thermostat piston and a spring returns the control plate closing the dampers.

CHANGEOVER

(TF-HC and TF-CW ONLY)

Changeover between the cooling and heating modes is determined by supply air temperature. A thermostat/actuator located in the inlet of the diffuser senses supply air temperature. Warming the changeover thermostat changes the TF to the heating mode by pivoting the control plate over center. As a result the cooling thermostat is disengaged and the heating thermostat engaged.

Changeover from cooling to heating begins at supply air temperature 76°F/24.5°C and completes at 80°F/26.5°C. Changeover back to cooling begins at 72°F/22°C and completes at 68°F/20°C. During changeover the damper is closed or at minimum flow. The control plate pivots over center, first closing the damper and then opening it.

HEATING MODE

(TF-CW ONLY)

In the heating mode, the dampers are fully opened and will remain fully opened until the diffuser changes back from heating to cooling mode.

HEATING MODE (TF-HC ONLY)

In the heating mode, the dampers open on a drop in room temperature. As the room cools, the wax in the room thermostats contracts. A spring retracts the piston in the heating thermostat allowing a spring to pivot the control plate, opening the dampers allowing more supply air into the room.

ADJUSTING SET POINTS

Heating and cooling set points are separately adjusted by turning the heating and cooling thermostats (fig.2). Align the white indicator on each thermostat with its respective temperature scale. Each set point can be anywhere between 70°F/21°C and 78°F/25.5°C. Both are factory set at 74°F/23°C. (The model TF-CW and TF-C have only a cooling thermostat).

OPEN FOR BALANCING

To open, unhook the tension spring from the bracket adjacent to the cooling thermostat and turn the control plate slightly to drop the dampers open (fig.3).

MINIMUM FLOW

To drive room air sensing, primary air is continuously supplied through the four venture nozzles even when the dampers are closed. The nozzles supply approximately 35cfm/16l/s at 0.15”wg/37Pa (fig.4). If required, additional minimum flow is available for both fixed and adjustable flow stops (see Options).

SYSTEM DESIGN

The best control for heating/cooling units supplying air to VAV terminals is a discharge thermostat which maintains a constant supply air temperature. With DX equipment these are a high and low limit. Use a room thermostat for changeover between heating and cooling modes. For hybrid systems (part VAV and part constant volume) control the heating/ cooling supply unit with a thermostat in one of the rooms with a constant volume diffuser, preferably the space with the greatest load. For both VAV and hybrid systems, the fan should run continuously. The constant discharge velocity of Therma-Fuser diffusers at varying air flow provides good room circulation

which reduces stratification. Keeping heating supply air temperatures as low as possible will further reduce room air stratification to a negligible level.

Static pressure at the inlet of the ThermaFuser diffuser should be between .05"wg/12Pa and .25"wg/62Pa, at full and partial air flows. Static pressure below .05"wg/12Pa will result in low air flow and less induction. Above .25"wg/62Pa, ThermaFuser diffusers operate well but excessive noise may result. Use minimum flow settings where tight shut off is not needed. If the system turns down more than 30%, static pressure should be controlled. Included in the options for static pressure control are fan speed control and modulating bypass dampers. Modulating zone dampers are recommended where several zones share a higher pressure duct or riser.

When designing ducts, if Therma-Fuser diffusers are to deliver nominal volume at inlet SP of .15"wg/37Pa and if a maximum SP of .25"wg/62Pa is to be held for quiet operation, size the duct for a maximum pressure drop of .1"wg/25Pa between the first and last takeoff.

Manual balancing dampers should be used at the takeoff for each diffuser. Manual balancing dampers may not be required with ducts designed to Acutherm specifications.

Because Therma-Fuser diffusers control room temperature by sensing room air induced up the center of the space, care should be taken not to disturb room air induction and entrainment. For example, location next to walls or dropped lights results in the reflection of primary air back at the Therma-Fuser diffuser. Relocate either the Therma-Fuser diffuser or the light. Acutherm has “how to” system design brochures for almost every ducted air system. For specific recommendations refer to the brochure for your system.

Guma’ Hustisia

Air Conditioning and Mold Removal and Remediation Project Report No. 2 – March 29, 2018

A. Overview

On Thursday, March 22, the Judiciary released its First Preliminary Report on the Guma’ Hustisia Air Conditioning and Mold Removal and Remediation Project. In the March 22 Preliminary Report, we provided background on the air conditioning and mold issues plaguing the Guma’ Hustisia. We also detailed the steps the Judiciary has taken to manage the building’s closure since the air conditioning shutdown on Friday, March 16, as well as outlining our shortand long-term goals for managing the Judiciary’s operations and restoring the Guma’ Hustisia. Please refer to the March 22 Preliminary Report for such information.

In this Report, we detail our progress over the previous week and justify each of our objectives. We hope this correspondence will assist the Executive and Legislative branches in providing immediate financial and technical assistance for the assessment and remediation of mold and procurement of an air conditioning system.

The Project estimate now totals $7 million 1:

• Air-conditioning system: $4.4 million

• Mold removal and remediation, including collateral expenses: $2.6 million

B. Current Status: March 22–March 29

Since the March 22 Preliminary Report, we continued gathering information on the mold and airconditioning issues and providing court proceedings and services at alternate locations, including the U.S. District Court in Garapan, Department of Public Safety offices, Pedro P. Tenorio Multipurpose Center, and the RSAT building in Susupe.

1. The Judiciary has disseminated information and set up channels for ensuring communication while divisions are segmented.

1.1 Following the Judiciary leadership team’s meeting with Governor Ralph DLG Torres on March 22, the members of the bench met to discuss new developments.

1.2 On March 26, the Judiciary held a general assembly, briefing employees on the Judiciary’s current state and opening the floor for questions, comments and suggestions.

1 This figure has increased from the $5 million estimate provided in the March 22 Preliminary Report as the Judiciary has gathered further information.

THE JUDICIARY - COMMONWEALTH OF THE NORTHERN MARIANA ISLANDS

1.3 Since March 26, the Judiciary’s managers have met daily to facilitate spread of information between divisions.

1.4 On March 28, Judicial Council members met with Speaker Rafael S. Demapan and President Arnold S. Palacios to discuss the Guma’ Hustisia’s status.

1.5 On March 29, the Judiciary met with the CNMI Bar Association to update the bar on the ongoing status of the Guma’ Hustisia.

1.6 On March 29, the Judicial Council adopted a resolution requesting the Executive and Legislative branches for financial and technical assistance in the amount of $7 million.

2. We have continued our mold remediation efforts.

2.1 On March 26, BEH conducted a second assessment of the building and reported the existence of mold.

2.2 Carpeting has been removed in multiple locations and unnecessary books and papers are being relocated.

2.3 Masks have been made available to employees entering the building.

2.4 Industrial hygienists capable of providing mold remediation assessment services have been identified on island.

2.5 Plans to prevent future mold growth are also being developed.

3. Planning for air-conditioning replacement is also occurring.

3.1 The partially-functioning chiller continues to be operated, but may breakdown at any time The unit is running below optimal design specifications, operating on a manual switch that must be monitored daily for proper pressurization and other mechanical operation. The unit is incapable of providing the appropriate cooling temperature in the building. The backup units remain inoperable

3.2 Stand-up air-conditioning units are in the process of being procured before the remaining chiller ceases to function.

4. We continue to explore satellite offices for court services while attempting to address challenges that have arisen due to the Judiciary’s segmented operations.

4.1 Marshals are stretched thin monitoring multiple locations while serving arrest warrants and providing bench protection.

4.2 Members of the public are forced to wait outside buildings in long lines to access many of the Judiciary’s services.

4.3 Operations are stymied while employees without laptops or remote access to documents wait for assistance.

In summary, divisions are stretched thin and prolonged satellite operations may cause certain Judiciary services to cease operation. Further mold removal and remediation plans require additional funding and expedited procurement. As with mold removal and remediation, further steps regarding system-wide replacement of our air-conditioning system require additional funding and expedited procurement.

C. Objectives

The Judiciary’s short-term and long-term goals allow restoration of the Guma’ Hustisia’s safety while facilitating operation of the judicial branch in the interim. Below, we detail our objectives and provide justifications. Updated funding figures will be provided in later reports.

1. Short-Term Goals

a. Monitor and Manually Operate the Remaining Partially-Functioning Chiller

i. While two of the Guma’ Hustisia’s three chillers are now completely inoperable, one chiller was brought partially on-line on Wednesday, March 21.

ii. Because the unit’s control board is nonresponsive, it is running on a manual switch. Manual operation of the chiller requires daily maintenance bythe building maintenance manager and an airconditioning specialist. The chiller may breakdown at any time because of its advanced age, deteriorating condition, and recent bypass repair. Additionally, it is only partially operating: the chiller has only been able to produce 50-55-degree water, as opposed to its ideal temperature of 45-47 degrees.

iii. Although the chiller is insufficient for long-term operation, it should continue to run while the air conditioning system is replaced and moldremediation is done. This will slow mold growth and provide airflow for employees tasked with cleaning the building.

b. Receive and Analyze Results of BEH Mold Assessment

i. The Bureau of Environmental Health conducted an initial assessment of the Guma’ Hustisia on Wednesday, March 22. BEH conducted a follow-up mold assessment on Monday, March 26. Receipt of BEH’s report will allow the Judiciary to further assess the extent of mold remediation efforts needed.

c. Hire Industrial Hygienist to Review and Evaluate Potentially Problematic Environmental Factors and Facilitate Proper Cleaning

i. An industrial hygienist tests workplace environmental hazards, determines if they pose a health risk, and recommends means of controlling or eradicating the health hazard. An industrial hygienist is needed to examine the presence of mold in the Guma’ Hustisia. The hygienist’s help is needed to assess where the mold is located, how to properly remove the mold, what type of mold is present, and other related concerns.

ii. Mold removal and remediation efforts may not properly begin until an industrial hygienist has made an assessment.

iii. Two industrial hygienists have preliminarily assessed the Guma’ Hustisia and an additional hygienist will soon perform another initial review. However, without procurement processes in place the Judiciary is unable to proceed further with obtaining a hygienist.

d. Remove Furniture, Carpeting, and Materials that Exacerbate Mold Growth

i. As discussed in the FY 2019 Budget Request, the Office of the Governor’s Capital Improvement Project (CIP) provided funding and oversight for the hiring of an engineering firm to assess the building’s mold issue.

ii. The engineering firm recommended we remove all carpet, furniture, books, paper, clothing, and sagging ceiling tiles infested by mold.

iii. The Judiciary intends to heed this recommendation and not only remove items affected by mold, but also remove items that have the potential to exacerbate mold growth. This includes removal of furniture, books, and paper from offices. It also includes removing and replacing carpeting. Such steps will require additional assistance from employees and procurement of a company to replace flooring.

e. Procure Services of an Industrial Hygienist and Other Professionals to Remove Mold

i. Once an industrial hygienist assesses the Guma’ Hustisia, we will follow any cleaning recommendations provided These recommendations may include professionally cleaning furniture, walls, air vents, and other areas.

ii. Such cleaning services are beyond the scope of the Judiciary’s current janitorial services and will require procurement of an outside company, necessitating additional funding.

f. Procure Stand-Up Air-Conditioning Units for Peripheral Offices

i. Stand-up air-conditioning units will allow air circulation and prevent mold growth while a permanent air-conditioning system is installed

ii. Because the stand-up units require drainage, they may only be placed in peripheral offices. As such, these units are insufficient to function as a long-term air-conditioning system for the Guma’ Hustisia. However, these units will allow the Judiciary to return its operations to the Guma’ Hustisia more quickly.

iii. Governor Ralph DLG Torres has kindly promised to provide funding for the stand-up air conditioning units.

g. Secure Funding for Drug Court and Information Technology Satellite Office

i. The Judiciary had been pursuing alternative sources of funding to establish a satellite office for Drug Court on Capitol Hill, applying for a SNILD grant as recently as February 6, 2018. The satellite office was requested in order to secure storage of back-up court information and provide emergency court services during and after emergencies.

ii. Given the shutdown of the Guma’ Hustisia, Drug Court proceedings have been moved to an alternative site. Currently, Drug Court and Family Court proceedings are operating in the same hallway, resulting in the overlap of proceedings that each raise confidentiality concerns.

iii. Due to these unforeseen circumstances, the grant request must be set aside in lieu of a faster solution. The Judiciary requests the Legislature’s financial assistance in establishing the Drug Court satellite office in house units 1361 and 1362.

2. Long-Term Goals

a. Install New Air-Conditioning System

i. Because two of the air-conditioning system’s chillers are in disrepair and one chiller is barely functioning, restoration of Judiciary operations in the Guma’ Hustisia will require the installation of a new air-conditioning system. According to the engineering firm’s recommendations, this overhaul includes replacing air handling units, water pumps, and remote air-cooled condensers, amongst other components. Because these units must be designed specifically for the Guma’ Hustisia, their manufacture and shipment will require several months.

b. Complete Clean-Up and Mold Removal

i. Mold is a serious concern for the people of the Commonwealth, and as a completely sealed building, the Guma’ Hustisia requires continuous monitoring. Ongoing mold removal and remediation efforts will be required in order to provide a safe environment for court staff and the public.

ii. Each clean-up and mold removal session will involve hiring an outside company, necessitating additional funds.

D. Conclusion

The Judiciary continues operating critical services from satellite locations while developing and implementing short and long-term plans to restore the Guma’ Hustisia.

The air-conditioning system shutdown exacerbated mold growth throughout the building. The partially-operating chiller is only mitigating the growth of mold; once this chiller breaks down, mold growth may damage the building beyond repair. Delayed action will further exacerbate the spread of mold throughout the Guma’ Hustisia, resulting in increased costs, delays, and health concerns. It is imperative that immediate action be taken stop the spread of the mold and investigate the degree of mold damage done to the building.

The initial cost estimates for both the short-term and long-term objectives may well exceed current estimates.
