< UPFRONT the next step it is difficult to Imagine wasting 14 000 Of ANYTHING, YET IT HAPPENS each year in the U.S. and I suspect the

numbers would not be much different for Canada.* The number, in gallons, is the amount of water a household of four sends down the drain annually while waiting for hot water to flow. This is the equivalent of 52 996 litres or enough water to fill a 7.3-meter (24-foot) diameter, 1.2-meter (four-foot) deep swimming pool. These are pretty good numbers if you are trying to sell your customers on the benefits of a recirculating domestic hot water system.

John Siegenthaler discusses these systems in Stemming The Flow, our cover story this issue. He notes that the fallout from this seemingly innocuous activity goes beyond the obvious and includes increased water and sewer bills, energy waste and added strain on treatment streams–coming and going.

Water, contrary to popular belief, is not an endless resource. The water issue has the potential to prompt great dissent among neighbours, municipalities and nations. Prince Edward Island recently made national news as a Charlottetown man vocalized his desire to have the provincial government put tighter controls on the amount of water the city can use. This is just one example, but likely a harbinger of things to come. How we use water and protect the resource will come under increasing scrutiny.

With World Plumbing Day behind us and awareness bumped up a notch, it is time to push recirculation and other options available to homeowners to significantly reduce water use. Low flow products have hit their stride and consumers are satisfied, in fact these products are now the norm. Remembering that money talks, even your customers who have not fully embraced conservation cannot deny the dollar and cents of taking the next step.

Editor * An effort to source Canadian data was unsuccessful, but conservation groups HPAC approached did note that research into the issue was warranted.

John Chiasson February 27, 1968-February 11, 2013 On February 11, 2013, we lost a valued colleague when HPAC’s account manager John Chiasson died after a brief illness.

An avid sports fan, John not only loved the Maple Leafs, he and his wife Tracey traveled the globe to take in various sporting events, including the 2012 UEFA European Football Championship in Poland and the Ukraine, and the 21st Winter Olympics in Vancouver, BC. We will miss John's gentlemanly manner, cheesy sense of humour (of which he was quite proud) and his presence in the office and at industry events.

Tax reform key to improved energy efficiency say industry stakeholders The group known as the Building Energy Efficiency Coalition (BEEC), which includes the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), the Canadian Institute of Plumbing & Heating (CIPH) and the Mechanical Contractors Association of Canada (MCAC), recently submitted a detailed submission to the Federal Minister of Finance and the Minister of Natural Resources. The group is seeking an expansion in the equipment included in Class 43.2 of the Income Tax Act. Items requested for inclusion in CCA Class 43.2 include: removing an existing limit so that the installation of heat recovery ventilators in multi-family buildings or commercial/industrial buildings would qualify; make active solar equipment eligible when it is used to heat water for swimming pools in hotels and multi-family buildings; make eligible high efficiency heating boilers and furnaces (including any associated pumps, fans, variable speed drives, VAV boxes, dampers, piping, insulation and like equipment, as well as installation costs) when the boilers or furnaces are installed with duct work or chimneys or other building renovations that have a cost of at least 50

per cent of the cost of the boiler or furnace itself; and make high-efficiency chillers eligible when the increase in efficiency over the existing installation is at least a defined threshold, and is certified by a qualified energy engineer or certified advisor.

The BEEC believes that in most cases the revised tax treatment of the energy efficiency retrofit investments in Canada will increase government revenue. By saving substantial energy costs, the reform will enable the government to gain tax revenue from the increased net income of the building owner. That is in addition to taxes gained on the profits and wages earned by the manufacturers and installers of the energy efficient equipment, and on the increased wages earned the new workers who are hired.

See www.cfaa-fcapi.org/BEECproposal.phb for details on submission. BEEC members also include the: Canadian Federation of Apartment Associations (CFAA), Real Property Association of Canada (REALpac), Canadian Construction Association (CCA), Thermal Insulation Association of Canada (TIAC), Association of Energy Engineers – Southern Ontario Chapter (AEE-SOC), and Energy Services Association of Canada (ESA).

With 25 years of experience in Canada, Saniflo, the worldwide leader of macerating toilet systems, has once again raised the bar by creating a system that requires less time on the job site for contractors and minimal stress for the do-it-yourselfers. The SANIACCESS 3 is an easy-to-open double-panel macerating unit that provides easy access to the internal components so that periodic maintenance can be easily accomplished in any home or building.

The SANIACCESS 3 incorporates two easy-to-open service panels located atop the unit on either side. One panel allows access to the electrical components as well as the level sensor mechanism of the macerator while the other accesses the basket area around the macerating blades to allow easy removal of any large objects that may have been accidentally flushed.

The unit can accommodate a complete bathroom (including a sink, a shower and/ or bathtub) and discharges waste up to 15 feet vertically and nearly 150 feet horizontally, while operating quietly with sound-absorbing technology.

Why maceration?

Macerating technology is a cost-effective, easy-to-install solution for both residential and commercial bathroom applications. The systems use a fast-rotating blade to liquefy waste and toilet paper in the flush water, which is then discharged under pressure through small-bore piping to a drainage line or soil stack.

Saniflo Canada macerating toilet systems can be installed on top of any finished floor eliminating the need for excavation of the existing floor or building a raised floor to install a drain line, as required by systems using a sewage ejector. The small-bore discharge piping can easily be installed and concealed inside existing walls. Saniflo’s “up-flush” technology permits home or building owners to create a new bathroom wherever it is most convenient: in a basement, attic, garage, under the stairs or inside a newly remodelled space.

Where to buy Saniflo Canada offers a complete line of macerating toilet systems as well as gray water pumping systems for residential and commercial applications. Saniflo products are available at plumbing wholesalers and hardware retailers located throughout the country.

Stemming The Flow

Balancing a recirculating domestic hot water system. BY John Siegenthaler

A

n annoying characteristic of many plumbing systems is when a person opens a hot water tap, but has to wait several seconds for warm water to flow from that tap. This happens because there has not been a draw of hot water for some time and the water left in the piping from the previous draw has cooled off.

The US Department of Energy estimates that an average family of four wastes up to 14 000 gallons of water annually, simply by opening taps, and waiting for hot water to arrive.

This obviously increases water and sewer bills, adds to sewage treatment streams and wastes energy. In warmer months, the heat lost from hot water piping also adds to the building’s cooling load.

One of the solutions to this situation is to create a recirculating domestic hot water system. The basic idea is simple, and illustrated in Figure 1.

In this system, hot water, presumably at maximum temperature no higher than 120F, flows from the storage water heater through the building’s hot water supply piping. After the hot water supply pipe tees off to the last fixture, it connects to a smaller diameter return pipe that goes back to the storage tank. A small bronze or stainless steel circulator creates just enough flow keep the temperature drop along the

hot water supply main to perhaps 2F to 4F. Each fixture is now within a few feet of piping that has hot water in it, at least when hot water service is deemed necessary. In some buildings, recirculating hot water is available 24 hours per day, and seven days per week. In other buildings, hot water recirculation is controlled by a timer or other controller.

Turning off the recirculation system at night saves energy. If someone has to have hot water at 3:00 a.m., they may either open the tap and wait for it, or in some systems, press a button that immediately starts the recirculation circulator and operates it for a short override period.

A check valve is installed downstream of the recirculation circulator. Its purpose is to prevent any cold water from being drawn backward through the recirculation pipe, and eventually to a hot water tap, if the recirculation circulator is not operating.

To minimize heat loss, it is crucial that the hot water supply pipe, the return pipe and the hot water risers to each fixture are insulated. Without code provisions that require otherwise, I suggest a minimum of ½-inch thick foam rubber insulation, or equivalent on all hot water piping.

DO NOT GO UNPROTECTED Although the system in Figure 1 is functional, it lacks the safety associated with either a single point-of-distribution (POD) thermostatic mixing valve near the water heater, or multiple point-of-use (POU) thermostatic mixing valves at each fixture. Without one of these means of protection, the temperature of water arriving at the fixtures will be essentially the same as the temperature at the top of the water heater. If the tank’s thermostat is set above 120F, or its temperature controller is inaccurate, or the tank is heated by some non-thermostatically limited heat source, such as solar collectors, the water arriving at the fixture could quickly scald someone. Such a situation can cause life-changing harm to an unsuspecting building occupant. I have a policy that no drawings or specifications involving domestic water heating ever leave our office without properly selected thermostatic mixing valves to protect against scalding. I am continually amazed at how many commercial properties have scalding hot water readily available at the taps. These situations are just lawsuits waiting to happen.

Figure 2 shows how the system from Figure 1 can be modified to include a POU thermostatic mixing valve at each hpacmag.com

“The us department of energy estimates that an average family of four wastes up to 14 000 gallons of water annually, simply by opening taps,

and waiting for hot water to arrive. lavatory. The shower valve has its own integral anti-scald protection mechanism.

This configuration allows the water temperature leaving the hot water source to be above 120F, such as may be necessary to kill Legionella bacteria. It also allows lower, individually set delivery temperatures at each fixture.

RECIRCULATION WITH POD MIXING VALVES So how can one design a domestic hot water delivery system that incorporates both recirculation, and protection from scalding? One common attempt at such a system is shown in Figure 3.

The mistake is to just tee the return side of the recirculating loop to the cold water pipe supplying the thermostatic mixing valve. Over time, this piping causes the cold port of the mixing valve to approach fully open, while the hot port approaches fully closed. Under this condition, there will be very little if any transfer of hot water from the water heater to the recirculating loop. This causes the temperature in the recirculating loop to drop, often well below the desired set point.

The correct method for incorporating a POD thermostatic mixing valve with recirculation is shown in Figure 4. This system includes a bypass valve (1), and a return valve (2). The purpose of these valves is to regulate how much warm water, from the return side of the recirculating loop, flows back to the storage tank. When there is no hot water draw at the fixtures, the water flow rate back to the tank will be matched by an equal flow of hot water from the tank, into the recirculatContinued on p20

Real World Corrosion Monitoring

Corrosion Monitoring System Service Pressure: 250 PSI Proof Burst Pressure: 10,000 PSI Operating Range: 35° to 200° F Thread Size: 1-½ in. NPT Manufacture: CNC Machined Finish: Corrosion Resistant

Corrosion at fire protection systems has the potential to destroy the piping in just a few years. In its worst form, sufficient iron oxide rust deposits can be created to completely clog the pipe and render the entire system useless.

And the corrosion occurring is totally hidden from view.

The CorrView corrosion monitor provides a simple to install, maintenance-free, and inexpensive method to monitor for hidden corrosion problems in any black steel fire protection system.

Threaded into any port, CorrView produces a brilliant white to fluorescent orange color change alert should a corrosion condition develop or pipe wall loss occur due to any cause.

CorrView was designed in response to the growing incidence of corrosion related failures at both wet and dry fire protection systems.

This simple and maintenance free device, having the form factor of a standard hex head shaped plug, acts as a virtual “Pipe Fuse” to provide round-the-clock corrosion monitoring protection.

Product Benefits Advance warning of a corrosion problem Monitors all forms of corrosion loss Reduced threat of clogged pipe Reduced property loss Ensure adequate water flow Continuous corrosion monitoring Totally passive Low cost

CorrView is simply taped and threaded into a tee, side port, saddle clamp, or any opening of the fire system at different locations.

Manufactured from the same mild carbon steel pipe material, its front surface corrodes as the pipe itself corrodes.

No maintenance demand

A front wear thickness dimension defines a safe, permissible amount of corrosion wear. When corroded beyond that limit, water enters its sealed chamber to produce a brilliant white to fluorescent orange color change at its sight glass indicating a potential corrosion problem and need for further investigation.

No power requirement

Simple and totally maintenance free, CorrView adds a significant new level of safety to any fire system. With an advanced warning now provided directly to the property owner, CorrView shifts the responsibility for a problem which is always hidden from view.

For problem free fire systems CorrView will continue to show its white safety indication for decades. Under high corrosion conditions, however, its bright color change will provide advanced notification to the problem in time to effect corrective actions.

CorrView helps to ensure that a fire system will save lives when called upon.

Simple screw-in installation Low installation cost

several minutes. Under this condition the supply water temperature leaving the thermostatic mixing valve will likely be lower than the setting of the mixing valve.

Slowly open the bypass valve (1) and monitor the temperature leaving the thermostatic mixing valve. It will likely begin rising as some water returns to the tank, and an equal flow of hot water moves from the tank to the hot port of the mixing valve. When the temperature leaving the mixing valve remains stable, and is at, or very close to, the temperature setting of the thermostatic mixing valve, the bypass valve is correctly set.

The return valve (2) can remain fully open unless a situation occurs where the bypass valve (1) is fully open, but the temperature leaving the mixing valve is still too low. If this happens, partially close the return valve (2) to add flow resistance. This forces more flow through the bypass valve (1).

Repeat the previously described procedure of slowly opening the bypass valve (1) until the water temperature leaving the mixing valve is stable.

The system should now provide a stable and safe supply water temperature to the hot water distribution piping. Hot water will be available to each fixture served by that piping within a second or two of opening a tap and thousands of gallons of otherwise wasted water will be saved every year. <>

PRESENTED BY

The new Ascent™ II macerating toilet system from Liberty Pumps allows easy installation of a bathroom in areas where no gravity sewer lines may exist! Perfect for remodeling applications, the Ascent™ II eliminates the need for major construction or breaking concrete floors in basements to add a bathroom. Featuring a 1.28 GPF (4.8 LPF) high efficiency toilet, the system easily macerates sewage waste and other debris with new RazorCut™ technology and then discharges it through a small 1” diameter line up to 25 feet (7.6 meters) high and 150 feet (46 meters) horizontally.

With tens of thousands of cycles and months of testing in a commercial installation, the RazorCut™ system easily handled sanitary napkins, paper towels and other difficult solids with ease. If something undesirable – such as a child’s action figure or toy were to get accidentally flushed, a removable service panel provides quick access to the cutter area without disconnecting the plumbing. A safety switch designed into the access cover automatically disconnects power when the cover is removed. This assures the unit will not energize while performing service.

Other features include IST™ solid state switching with Advance-Run-Technology. This unique feature assures the RazorCut™ system is spinning at full RPM prior to fluid and waste entering the cutter basket – greatly reducing start up load and improving macerating performance.

The system also features a built-in alarm with battery backup, rear discharging connections to eliminate unsightly rubber connectors and pipes exiting the macerator cover, LED lights and an external touchpad for alarm silence and manual system override.

The ADA compliant toilets – available in round front and elongated styles, have improved flush performance and carry the WaterSense™ mark. Both models feature insulated tanks to eliminate sweating.

Multiple Boiler Option When and how to use hybrid systems. BY mark norris

I

n the February 2013 issue of HPAC’s Modern Hydronics (available online at www.hpacmag.com) we looked at using multiple condensing boiler system design to help eliminate short cycling issues related to large building load turndown. Using more than one boiler in a system can also help keep the system in condensing mode and optimize efficiency when the proper controls are used and configured correctly.

One of the pitfalls identified was initial project cost for more than one boiler. We also saw that there may be at least a portion of the heating season where we need to operate with boiler return water temperatures that keep the flue gas Figure 1 Series piping layout.

temperatures above the dew point. During those periods condensing boiler(s) are not condensing. When that occurs, boiler efficiency is reduced to that of a good non-condensing boiler. With that in mind, is it worth adding another condensing boiler? Compared to the cost differences between condensing and non-condensing boilers how long will it take to recover those initial dollars when the boiler is not going to condense anyway?

It is questions like these that lead us to another option for multiple boiler systems: the hybrid boiler system. What is meant by hybrid is condensing and non condensing boilers together in the same plant. The non-condensing boiler will cost less than the condensing boiler to purchase. If the second boiler is only going to be needed when the system is operating outside of the condensing range, then why not save some money on the initial costs?

WHEN AND HOW DO I USE A HYBRID?

Figure 2 Multiple boiler system.

26

HPAC | MARCH 2013

First, let’s look at when to use a hybrid. If the system design or peak load temperature requirements mean that the return water temperature to the boilers is going to exceed 55C, then we could consider it. The higher the design temperature is the more often that condition will occur. As an example, assuming we are using an outdoor reset control setup, a system that requires 80C water with a 12C delta T will spend more time outside of the condensing range than one designed for 70C supply with the same Delta T. This is usually associated with systems incorporating higher temperature heat emitters, such as copper fin convectors, etc.

Next let’s look at how to use a hybrid. There are two considerations to make a hybrid system as efficient as possible.

The first is piping. The second is controls.

The piping design of the primary loop is important (yes, we should be looking at a primary secondary piping layout here).

We want to be able to send most if not all of the return water into the condensing boiler(s) first. This lets the boiler(s) that can benefit from cooler return temperature use it. The colder the return water temperature coming back to a condensing boiler, the more condensation we can expect. Sending colder water back to the non-condensing boiler on the other hand means we need to protect the boiler from that cold water with some form of low water protection. One way to lessen the need to protect the non-condensing boilers is letting the supply water from the condensing boiler feed the non-condensing boiler’s return. This elevates the water hpacmag.com

“If the second boiler is only going to be needed when the system is operating outside of the condensing range, then why not

”

save some money on the initial cost?

temperature the non-condensing boiler will see, reducing the amount of concern we have that the non-condensing boiler will be exposed to conditions where it may condense or experience thermal shock potential in lower temperature systems with larger Delta Ts (see Figure 1). The result is less use of the low temperature boiler protection for the non-condensing boiler. Low temperature protection is an important factor for longevity on non-condensing boilers operating in systems that may return low temperature water, but protecting the boiler has a cost. Sending heated supply water back to the boiler return via a four-way mixing valve, return water mixing valve or shunt pump, means that some of that heated water will not go to the system right away because it is being used to keep the boiler hot. Burner cycles used for the purpose of maintaining heat exchanger temperatures also cost fuel in an effort to protect the appliance. These are very important tasks for the longevity of the heating appliance, but as I said, there is a cost. Note that to simplify drawings we have not shown any piping related to the non-condensing boiler’s return water elevation packages.

The series piping layout in Figure 1 works OK of there are only two boilers. If the system turndown warrants it however, we may have more than one condensing boiler along with the non-condensing boiler, as shown in Figure 2.

The layout in Figure 2 however may result in periods where the second condensing boiler will see return water temperatures that are already preheated by the boiler ahead of it. But if we layout the system with a combination of series and parallel piping as shown in Figure 3, then both condensing boilers will see the lower return water temperature. We can rotate the lead lag operation of the two condensing boilers as we want to without affecting the cascade control’s PI calculations or the temperature of the second boiler’s return water. We also maintain the ability for the non-condensing boiler to see elevated return temperatures as in Figure 1.

the non-condensing boiler as the last boiler. A common supply sensor should be used to let the cascade control know what the combined temperature of all the boilers is.

Rotating the lead and lag operation of the boilers is mostly a choice made by preference of operation. It won’t generally change the efficiencies of the system as long as the least efficient boiler is always kept as the last boiler. Some people like to have equal wear on all of the boilers, while some think it is better not to have all of the boilers due for maintenance or repairs as a result of even wear all at once.

VENTING CONSIDERATIONS There are some considerations for venting that need to be addressed for hybrid systems. While all of the condensing boilers are going to be ULCS636 class II (category IV) positive pressure vented appliances, and may even be approved for common venting in some cases, the non-condensing boiler will not be compatible. Typically a non-condensing boiler will not require ULCS636 vent, or if it does, may require ULCS636 Class I type venting materials (category I or category III). Category I systems require a barometric damper or draft hood to control the overfire draft. Because noncondensing boilers have different venting requirements they cannot be combined with condensing boiler vents. We also need to examine the requirements for combustion air. While Continued on p30

Figure 3 Series and parallel piping combined

CONTROL SETTINGS There will be some specific control settings to establish. If there are only two boilers, the condensing boiler is always the lead boiler and the non-condensing boiler is always the lag boiler. If we have more than one condensing boiler then we can rotate their lead lag operation if we want but we should always keep hpacmag.com

Hybrid boiler system using a commercial condensing boiler with a modulating power burner along with a single-stage, atmospheric gas fired, non-condensing boiler.

If you have decided to go with multiple boilers, you may also want to go hybrid, but look carefully at all of the variables.

Once you layout the additional piping, install and set up the controls correctly, and add the necessary venting and combustion air equipment, you may find the costs very similar to going all condensing, even if there will be times when the boilers cannot condense. Be careful with boiler sizing. Do not oversize; remember that short cycling is an efficiency robber.

On the other hand do not undersize because a condensing boiler is not going to achieve its published efficiency when operating in a non-condensing mode and at higher burner modulation points.

One last thought; I have found that there is usually more benefit to hybrid designs for larger systems that have greater Btu loads with larger building turndowns than for smaller systems. <>

BII SUMP PUMP CHECK VALVES are designed with a full port valve body which allows the flapper to fully open, setting it apart from the competition. This un-obstructed flow design reduces friction loss and increases pumping efficiency resulting in higher flow rates. The design prevents debris from getting caught or building up ensuring a positive seal when the pump shuts off. All BII Sump Pump Check Valves have a 15째 angled valve seat ensuring faster closing of flapper upon pump shut off, which reduces back flow and water hammer noise, resulting in a quieter operation than valves without an angled valve seat.

Constructed from durable ABS (Acrylonitrile butadiene styrene) Boshart Industries carries a wide selection of configurations to meet the needs of every sump pump installation, allowing installation by threading directly into the pump discharge, by solvent welding to the pipe with the use of fittings, and with flexible rubber couplings & clamps or a combination of installation techniques. Inline models are available that come complete with straight or reducing flexible rubber couplings and corrosion resistant worm gear clamps (all stainless steel band, housing and screw) which prevent piping failure due to blow off.

BII SUMP PUMP CHECK VALVES have a thicker wall that helps to reduce the risk of damage and premature failure. The hose kits come complete with 24 feet of corrugated polyethylene tubing, one stainless steel worm gear clamp and one plastic adapter to thread directly into the pump discharge. The corrugated polyethylene sump pump tubing has flat sections for cutting the hose at 6 foot intervals allowing it to be customized for the installation, repaired or extended by joining multiple hose kits. The flat section once cut will ensure proper sealing onto an adapter or coupling with a clamp.

Cleanliness Is Next To…

PART I: Proper procedures for ensuring a contaminant-free installation.

BY dave demma

T

he long-term health of an air conditioning or refrigeration system is dependent on four things: proper design; quality installation; equipment commissioning; and ongoing preventive maintenance. Assuming that the system design engineer has done his job correctly, the burden of delivering a trouble free system falls upon the installing contractor.

It goes without saying that a reputable contractor who does quality work is essential in meeting that end. It also goes without saying that a contractor who fits that mould will not submit the least expensive bid for installation. The end user who selects a contractor solely on the “bid price” should remember the phrase “You get what you pay for.” It would also be helpful to remember the corollary to that phrase: “You can either pay me now (for a quality installation), or you can pay me a lot more at a later date (to correct the problems created by the low bid contractor).”

Ok, with a quality installation contractor on the job, there is one maxim that should be emblazoned in every technician’s mind: System cleanliness is vital to the long-term health of the system.

This process of system cleanliness starts with taking care

to ensure that no foreign particulate matter enters the system piping during the installation. The presence of particulate matter…trash…in the system can have any of the following negative impacts: 1. Control Valve Failure: Trash can restrict refrigerant flow by plugging up valve ports, orifices, small passageways in pilot assemblies utilized on pilot operated valves, and valve piston bores. This will respectively restrict refrigerant flow through the plugged valve port or orifice, restrict the ability of pilot assembly to pressurize and/or vent the piston chamber (necessary in pilot operated valves for piston modulation), and cause piston stickage due to the buildup of contaminant between the piston and piston bore. Many “alleged” valve failures are nothing more than flow restrictions due to trash; Restricted pilot ports in pilot operated EPR valves, Solenoid valves, and Discharge Bypass Valves preventing proper piston movement, or restricted main piston/port in TEVs preventing refrigerant flow (see Figure 1).

2. Plugged Filters-Driers, Filters, and Strainers. A plugged liquid line filter-drier will cause excessive pressure drop to the liquid refrigerant flowing through it. Where there is lit-

tle or no liquid subcooling present, refrigerant vaporization (flashing) will occur, reducing the supply of liquid refrigerant to the TEVs. The result is a loss in TEV capacity, which in turn results in a loss of heat transfer capacity. In extreme situations, particularly on systems without receivers, the plugged liquid filter-drier may result in increased head pressure.

A plugged suction filter will lower the pressure at the compressor inlet, increasing the compression ratio, and decreasing the compressor capacity. In mild cases additional compressor run time will be required to achieve the design temperature in the refrigerated space. In extreme cases the compressor capacity reduction will prevent the design temperature from being met.

Additionally, excessive suction filter pressure drop will significantly reduce the suction vapour velocity, preventing the oil from returning with the refrigerant to the compressor.

Some larger model compressors may come equipped with an inlet strainer; however the screen is typically course. This is by design; their purpose is simply to prevent larger particles from entering the compressor. Too fine of a strainer would plug up easily, resulting in an unusually high pressure drop between the compressor inlet and the cylinders. A plugged compressor inlet strainer will yield the same set of problems as a plugged suction filter (see Figure 2).

Multi-compressor systems utilizing an oil management system (oil separator and individual compressor oil level controls) will normally have an oil filter in the oil supply line to the oil level controls. If the oil filter becomes plugged, the oil level in each compressor crankcase will eventually drop to an unsafe level, causing the oil failure control to lock the compressor off.

3. Compressor Damage/Failure: Smaller trash particles will travel through the compressor inlet strainer (if indeed the compressor even employs one) and enter the crankcase.

RESIDUAL TRASH PARTICLES The first step in eliminating installation related trash particles is to implement a practice of flowing nitrogen through the copper piping during the brazing process. This will prevent the formation of copper oxide on the interior surface of the piping at the braze joint locations. Secondly, good practices and procedures should be used to prevent other forms of particulate matter from entering the piping (copper chips, brazing rod, sand, dirt, etc.). One often overlooked form of contamination comes from excessive amounts of flux being applied to dissimilar metal braze joints; this should be avoided.

Even with the best of intentions every system will have some residual trash particles remaining after the installation. This is why liquid line filter-driers are standard issue on all factory built equipment. As the name implies, part of the filter-drierâ&#x20AC;&#x2122;s function is to filter out destructive trash particles from the refrigerant and oil in the system. It is important to remove these trash particles before they have the opportunity to pass through the compressor. At startup, you have one shot to remove trash particles located between the compressor outlet and the liquid line filter-drier inlet before they can travel to the compressor. Given the importance in removing these trash particles on a first pass basis, a lower micron rated filter would be preferred for start-up situations. An optional secondary filter available in a removable liquid filter-drier shell is ideal. Figure 3 shows a replaceable liquid filter-drier shell with optional 20 micron secondary filter versus 40 microns for the standard core.

Figure 4 Sealed model and replaceable shell suction filters

Figure 3 Secondary filter for replaceable shell

Once there, the trash particles will travel through the compressor lubrication system with the oil, acting as an abrasive on bearings, bearing journals, piston rings, and piston cylinders. In extreme cases the oil sump inlet strainer or the compressorâ&#x20AC;&#x2122;s oil passageways can become plugged, resulting in a complete loss of lubrication. While it may take some time, the end result will be a failed compressor.

HPAC | MARCH 2013

Any trash particles located between the liquid line filterdrier outlet and the compressor inlet will have to pass through the compressor before the liquid filter-drier will have the opportunity to remove them. This is the “why” for using a suction line filter; it is undesirable to allow any trash particles to flow through the compressor before arriving at the inlet of the liquid filter-drier.

Smaller systems with close coupled piping runs, especially those built in the controlled environment of a manufacturing plant, may not require the use of a suction filter; the possibility of any measurable amount of trash between the liquid filter-drier outlet and the compressor inlet will be minimal.

Larger systems with remote compressors and lengthy runs of field installed piping are a much different story; particularly supermarkets and warehouses where the total length of piping may be measured in miles instead of feet. In applications such as this it is almost certain that significant amounts of trash will occupy the lengthy piping runs between the liquid filter-drier outlet and the compressor inlet. It is therefore essential to install a suction filter (or as required…suction filters) on systems with lengthy field installed piping runs.

Figure 4 shows a typical suction filter.

Suction filters and liquid filter-driers are the final check and balance to ensure that any residual contaminants remaining from the installation process are removed. They should be installed immediately prior to system evacuation. Suction filters and liquid filter-driers should not be viewed as a substitute for good installation practices, but rather as extra insurance against the inevitable residual particulate matter present after the installation.

SYSTEM EVACUATION: It should also be noted that the presence of moisture and/or air in the system will have devastating effects on long term system health. After the piping and component installation is complete, the system should be pressurized with dry nitrogen, or a mixture of dry nitrogen and a trace amount of refrigerant (following environmental guidelines) so a complete leak check can be performed. Any identified leaks should be repaired, and the system re-pressurized. If no drop in pressure is experienced over a 12 hour period, the system can be considered leak free. (Note: equipment manufacturer’s pressurization guidelines should be followed). Once leak free status is obtained the system should be evacuated.

“Why is it necessary for a refrigeration system (new or existing) to be evacuated?” Because the piping and components have been open and exposed to the atmosphere during the installation process.

ment of rare gasses and man-made pollutants, and some amount of water vapor. Here are the potential problems in forgoing system evacuation: 1. Non-Condensable Gasses: The function of the condenser is to transfer enough heat from the superheated discharge vapour to yield a saturated/subcooled liquid at its outlet. Any reduction in condenser capacity will have a negative impact on the condenser’s ability to perform this function.

Oxygen and nitrogen are both non-condensable at the temperatures normally experienced in the typical refrigeration condenser. If not removed from the system, they will accumulate in the condenser, taking up valuable space that should be reserved for refrigerant vapour to go through the change of state process. The subsequent reduction in condenser capacity will result in a higher condensing pressure (reduction in compressor capacity and higher electrical consumption) and a higher discharge temperature (the potential for the refrigerant and/or oil to suffer chemical breakdown at an accelerated rate.

2. Oxygen: Studies have shown that the rate of chemical breakdown increases when air (oxygen) is present in the refrigeration system. Its greatest threat is the potential to oxidize the compressor oil, which will occur at accelerated rates as the temperature increases (the rate of chemical reaction doubles for every 18Fº increase in temperature).

Oil that has suffered a chemical breakdown of this nature turns into a sludge and becomes acidic. Oil breakdown (sludge) may plug up control valves and affect proper lubrication of the compressor’s rings and bearings. Acid formation puts the insulation on hermetic compressor motor windings at risk of deterioration. Once the acid has eroded the winding insulation, shorting can occur, resulting in a failed motor.

3. Moisture: There are several problems with moisture in the Figure 5 Solubility of water in various liquid refrigerants

system: Studies have also proven that the rate of chemical breakdown (the formation of acids and oil breakdown) is accelerated if moisture is present in the system. The hydrogen in the water molecule can combine with the chlorine and/or fluorine molecules in the refrigerant to form HCl (Hydrochloric acid) or HFl (Hydrofluoric acid). Moisture can also cause corrosion, and accelerate the process of copper plating (where molecules of copper from the piping become displaced to heat bearing surfaces in the compressor, such as bearings and pistons).

In addition; every refrigerant has a water solubility curve, which will show the maximum water content (in PPM) that the refrigerant can hold in solution at a given temperature (see Figure 5). As the temperature is reduced, the ability to hold water in solution is also reduced.

For example, suppose the water content of the refrigerant in an R-22 refrigeration system operating at a +20F evaporator temperature is 1000 PPM. At a liquid refrigerant temperature of 80F 1000 PPM is below the solubility level for R-22, meaning that the water will be in solution with the refrigerant. The liquid refrigerant flows through the TEV, experiencing a reduction in pressure to 43 psi (20F).

At this temperature the refrigerant cannot hold anywhere near 1000 PPM of water in solution; the excess water comes out of solution, and exists as free water. In this application the refrigerant temperature is below 32F, and the free water will freeze, rendering the TEV inoperable, negatively affecting its ability to maintain its superheat set-point.

One of the more valuable tools in the technician’s arsenal is the vacuum pump; its function is to remove air and water vapour from the system prior to charging it with refrigerant.

During evacuation the vacuum pump accomplishes the following: (1) Creates a pressure differential between its inlet and the higher system pressure, allowing for the vapour to flow to the pump inlet, and (2) Reduces the system pressure to a point where any water that might be present will boil into a vapor. (Keep in mind that vacuum pump is a vapour pump only; it will not remove water in the liquid form).

In the next issue, Part II will review pressure and vacuum measurements and outline the steps involved in starting the evacuation process. In addition, more attention will be paid to the all important vacuum pump. Until then, may your systems run smoothly. <> Dave Demma holds a degree in refrigeration engineering and worked as a journeyman refrigeration technician before moving into the manufacturing sector where he regularly trains contractor and engineering groups.

Destratification can resolve a number of heating and air quality issues.

M

any facility managers dread the costs of keeping their workforce comfortable in spacious workplaces every winter. In other spaces, condensation can wreak havoc on products. It may seem counterintuitive, but for many facilities the answer to both these issues is better known for its summer cooling power: ceiling fans. More specifically, large diameter, low speed overhead fans can significantly reduce energy consumption, lowering energy costs by up to 35 per cent. The air movement from fans also clears condensation and the accompanying safety and product integrity problems.

“In large spaces, HVAC systems are generally not capable of efficiently distributing air to all occupants,” explains Christian Taber, senior applications engineer and ASHRAE High-Performance Building Professional for Big Ass Fans.

“Large circulator fans mix the air in the space, ensuring good air distribution and creating uniform temperatures that increase occupant comfort and minimize stratification.”

Large diameter, low speed fans produce a column-shaped jet of air roughly equal to the diameter of the fan. As this jet

strikes the floor it spreads out in all directions, displacing the stagnant air and setting up a convection-type circulation pattern. Air from the floor level is moved out towards the walls or obstructions and then moves up back into the fan to be recirculated. During cooling seasons the fan speed can be increased, so that faster-moving air working in concert with the body’s natural cooling process produces a cooling effect of up to 10F. Conversely, during heating seasons the fan speed can be reduced so that the air continues to mix, moving hotter air at the ceiling down to occupant level without causing a draft (see Figure 1). This destratification keeps occupants comfortable in heating seasons and may significantly reduce heating costs.

Let’s take a closer look at how these large fans solve two major wintertime issues in large facilities.

STRATIFICATION SITUATION In the winter, stratification, or layering, occurs because the hot air from a heater is approximately five to seven per cent lighter than cool air in a space and tends to rise to the

ceiling. In the winter, large diameter fans can be used for destratification by gently pushing the warm air trapped at the ceiling down to occupant level, creating a more uniform temperature throughout the space without causing a draft.

In addition to providing comfort to occupants, destratifying the air in a space has the added benefit of allowing for a lower thermostat set point.

A major focus for estimating winter energy savings is the difference in air temperature between the floor level and the underside of the roof, as well as taking into consideration outdoor air temperatures, with the assumption that after thermal destratification the air temperature will be essentially uniform within the space. An estimate of energy savings would consider the building envelope and the difference between heat lost through the roof and the two temperature differences before and after destratification, among other factors.

Occupants of existing buildings can easily access data through their local utility companies regarding the amount of gas or other fuel used during a heating season, while local climate records can provide average outdoor air temperature during a particular heating season. This data can be used to calculate the overall rate of heat loss through the building envelope in a stratified condition over a given period in Btu/ft²/degree day. [A degree day is used to relate the day’s temperature to the energy demands of the heating system, using 65 degrees as a baseline.]

Federated Co-operative Ltd., a retail cooperative with members throughout western Canada, operates retail shops, fueling stations, building material supply centers and refineries, occupying numerous warehouse spaces to store their products. Federated used large diameter, low speed fans to decrease the rate at which their buildings were shedding heat.

Trevor Carlson, manager of environmental and technical services, decided to conduct pilot tests in the 80 000-sq.-ft. loading dock section of their 300 000-sq.-ft. Saskatoon warehouse. These tests included the installation of five 24-ft. diameter fans.

Carlson tracked data concerning average energy consumption and daily temperature changes throughout two full years. The heating index of this facility before the installation of the fans was 4.49 Btu/ft²/degree day. Within the first year after installation, Federated saw a decrease to 3.99 Btu/ft²/degree day and the following year, a full year of using the fans, their heating index was 3.61 Btu/ft²/ degree day.

“We noticed a pretty significant decrease in natural gas consumption,” Carlson said. “We believe we saved $19,800 in the first year in natural gas consumption as a result of the fans. That’s a payback of approximately three years on the project.”

Solving issues in atria designs Manitoba Hydro moved into its 700 000 sq. ft. high-rise headquarters in September 2009. Nearly all of the building’s electricity comes from self-renewing water power, and the structure takes advantage of advanced technologies that respond to the harsh local climate. Located in downtown Winnipeg, the tower consumes only 88 kWh/m²/a–less than a quarter of the 400 kWh/m²/a typical of a large-scale North American office tower located in a more temperate climate.

Instead of recycling air, Manitoba introduces 100 per cent fresh air year round, regardless of outside temperatures. During the colder months, the outside air must be heated. As a result, the hot air rises to the ceilings in the three atria. At times, the floor temperature remained 10C (50F) while the ceiling temperature settled at a toasty 30C (86F). To eliminate this stratification in the 75-ft. high atria, three 14-ft. fans recirculate the warmed air, minimizing the discrepancy to five degrees or less.

Even though energy conservation was a focal point of the overall design, employee comfort and satisfaction was the primary concern. Mark Pauls, hydro energy engineer with Manitoba Hydro, notes that all employee costs were considered in the development of the tower. “Because our employee costs are roughly 100 times our utility bill, if we improve productivity and decrease absenteeism by one per cent each, that dwarfs any energy savings we would ever see.” explains Pauls.

CONDENSATION CONUNDRUM It is easy to assume cold storage is elementary; seal and insulate the walls, install a heavy door and turn the thermostat low. However, there is much more involved in maintaining a well-chilled storage facility. Sometimes even the most carefully designed facilities can encounter problems including dead spots and ice buildup. Introducing air movement has proven to be an effective way to curtail these issues and provide a more uniform cold storage environment.

Condensation was a big problem at McCain Foods production plant in Carberry, MB. Drops of water forming frozen stalactites had the potential to contaminate product, leading the Canadian Food Inspection Agency to express concern about ice buildup.

“We have different air pressures in the factory. In the process area you have very moist air that is at higher pressure than the air in the freezer. What happens is that moist air comes down through the freezing tunnels and out the conveyor holes in the wall and infiltrates the freezer,” explains chief engineer Geoffrey Aitchison. A 24-ft. diameter fan proved to be a simple solution.

“After two weeks the ceiling was completely clear and it has been ever since,” Aitchison said. “The air is circulating, plus we’re warming the ceiling to the same temperature as the air, so the frost isn’t going to stay there.”

With great success in its freezer, McCain Foods added another 24-ft. fan to its processing area, where condensation was forming on the ceiling above a processing tank and constantly growing mold.

Just like in the freezer, the tremendous air circulation abilities of the fan kept the ceiling and air temperature consistent, preventing the moisture buildup that allows mould to form.

Along with reducing condensation and creating consistent temperatures, large diameter fans also aid McCain Foods’ energy efficiency plans. Since the installation of their first fans in 2007, McCain Foods Canada has installed additional fans in other processing facilities. <> Erin Hsu is with Big Ass Fans.

New look for Hercules plumbing products

Stan Parzygnat honoured for philanthropy

Oatey SCS has updated its Hercules-brand packaging. The labels incorporate several design updates, making each label more consistent and easier to read with larger fonts, bold design elements and bigger product names. The standard colours: purple primers (and UnPurple too), yellow cleaners and orange CPVC cements, will remain the same as will the formulas.

The most notable change is the introduction of a new character on each label. The Hercules “mascot” is the personification of the Hercules brand – tough, bold, futuristic, innovative and most of all, fun, say Oatey representatives. The character will appear first on solvent cements, then eventually on the remainder of the product line.

Oatey SCS has also updated its solvent cement packaging to be compliant with the new Globally Harmonized System of Classification and Labeling of Chemicals (GHS) standards taking effect in June 2015. GHS is a worldwide initiative to promote standard criteria for classifying chemicals according to health, physical and environmental hazards. It uses pictograms, hazard statements, and the signal words “Danger” and “Warning” to communicate hazard information on product labels and safety data sheets (SDS) in a logical and comprehensive way. GHS has been adopted in 15 countries or economic regions. Oatey SCS sells its plumbing products in more than 70 countries. www.oatey.com

Smart circulators use up to 70% less energy Xylem innovation at the heart of Bell & Gossett’s ECM technology

The days of wasted electrical energy and thousands of gallons of wasted water due to inefficient circulators in hydronic systems are a thing of the past for many smart Canadian building owners.

Thanks to the advent of Electronically Commutated Motor (ECM) technology, a new era of “smart” circulators is saving savvy building owners significant money on their electrical and water bills. The new technology eliminates the need for a conventional shaft, seal and bearing assembly, and adjusts flow to meet demand. This allows these smart pumps to use up to 70 percent less energy than standard circulating pumps.

The rotor/impeller is the only moving part in the entire pump and it is magnetically balanced on a stationery ceramic bearing inside the pump housing to provide silent, long-lasting operation for both commercial and residential applications. The technology also keeps hot water automatically circulating throughout the system and can save thousands of gallons of water a year for building owners – water that would normally be wasted by tenants who let the water run while waiting for it to get hot.

t is impossible to know how well you are doing if you do not keep score. And it is really difficult to improve if you cannot track your results. That is why athletes practice by competing against established metrics. In sports it is commonplace to recognize that what you keep track of, you improve. What you do not focus on does not get better.

The same is true in business. If you want to collect your receivables faster, the first step is to start keeping track of them and seeing how quickly you are being paid and which accounts are problematic. Preparing an aged receivables trial balance allows you to you focus on customers who pay late. Once you know whom they are, you can figure out how to deal with them. You may even decide that some of your problem accounts are not worth keeping. Most companies do this as an aid to growth. Freeing up the energy required to service problem customers is one of the best ways to develop your enterprise.

The difficulty for many businesses, especially small ones, is that there are so many numbers to deal with, so many demands during the workday, and so little time that it is nearly impossible to keep track of everything. And even if you could keep track of everything, what would it tell you? You need comparisons to know if you are doing well or not. When an amateur golfer breaks 100, he can begin to feel better about his game. When he gets below 80, it is time for celebration.

But how do you know if you are doing okay on inventory controls, or if your rent expense is out of line? The problem is: out of line compared to what?

There is an Industry Canada web tool that is very helpful in this kind of exercise. The benchmarking instrument is found at www.ic.gc.ca/eic/site/pp-pp.nsf/eng/home.

Go to the site and you will see a set of reports available for different kinds of contracting businesses. Select Plumbing and Heating, and you will be taken to a page dealing with HVAC contractors. You can generate reports for the industry as a whole, which covers statistics for over 20â&#x20AC;&#x2030;000 companies with annual revenues ranging from $30,000 to $5 million. Broad stroke information like this is useful for someone wanting to sell to industry members, but it is too wide a selection to help you understand your own situation. It makes more sense to focus on businesses around your own size.

The tool allows you to select statistics for the four industry quartiles based on sales. The fourth quartile includes the numbers from the smallest 5000 companies in the group.

The third quartile contains the next largest 5000 companies, and so on.

The companies in the lowest quartile are very small. Their revenues range from $30,000 to $82,000 â&#x20AC;&#x201C; so it is pretty hpacmag.com

clear that these are startups or companies where the owner does most of the work and perhaps does not even work fulltime. The third quartile covers companies with revenues in the $82,000 to $190,000 range. Again, the numbers are quite modest. This is a reminder that half the companies in the field are really one or two people working together with perhaps a single employee. The second quartile companies have revenues from $190,000 to $530,000. And the first quartile companies range in revenue from $530,000 to $5 million.

Looking at the difference between companies in the first and second quartiles is illuminating. First quartile companies have direct costs that are 64 per cent of sales. That figure includes direct labour (20 per cent) and materials (44 per cent).

The first quartile companies have indirect costs of 30 per cent. That leaves them with a net profit before tax of just six per cent. The largest indirect cost categories are labour and commissions at 14 per cent, and insurance at eight per cent.

Cost breakdowns for second quartile companies are very different. Direct costs are significantly less and indirect costs are higher. Direct labour is 10 per cent (compared to 20 per cent for larger companies). Materials are 39 per cent (first quartile 44 per cent). Indirect costs are 41 per cent of sales compared to just 30 per cent for first quartile companies. Net profit for second quartile companies is 10 per cent of sales (compared to six per cent for larger companies). The largest expenses for second quartile companies are labour and commissions and insurance, the same as first quartile companies. But the percentages for these expenses are significantly higher for the small firms â&#x20AC;&#x201C; 17 per cent for labour and commissions and 12 per cent for insurance (compared with 14 per cent and eight per cent for the first quartile).

Just this simple analysis tells us some interesting things, and it provides hints about future problems. If you want to

hpacmag.com

make the jump from a mid-second quartile company (grossing say $300,000 per year) to a first quartile company (with revenues of say $1 million) your cost of production will rise.

That is because you will be depending more on employees and subcontractors to do work that you may do yourself now.

Your own salary will shift from direct labour to overhead, which is why direct labour costs for larger companies is a higher percentage, but with your increased sales, your overheads should decline as a percentage of your gross.

The key point here is that if it is going to succeed, your business will have to become more systematized as you grow. That is because you will need to depend more on other people. Decisions that can be made personally in a one or two person shop need to be formalized as the company grows larger. That requires an investment in strategic planning, which can sometimes be difficult. The reason why most companies do not make it into the first quartile is that the owners do not have the ability to convert what they personally do into a system that frees up their energies to develop growth. Most of us prefer to stay in our personal comfort zones. Growth is more difficult than it appears because it requires a change in behaviour.

If you decide not to grow, you can increase profits by becoming more efficient. Comparison tools are helpful for that, because they allow you to focus on areas of possible improvement for cost controls. On the other hand, if you are aim is to grow, comparison tools are also important. They can help you formulate a plan to evolve your company into its next stage of development. <> Hank Bulmash, MBA, CA, TEP, is senior partner with Bulmash Cullemore Chartered Accountants and is president of its consultant subsidiary BusinessLab Inc.

PRESENTED BY

Get In Touch…with Increased Energy Efficiency, Reduced Maintenance Time, LEED credits and More Comfortable Building Occupants Unique Touchscreen Interface on IAQPoint2 three-in-one IAQ Monitor from Honeywell Analytics Offers a Simpler Way to Boost Energy Savings and Fresh-Air Comfort Three-In-One IAQ Monitoring Honeywell Analytics introduces IAQPoint2, an innovative, touchscreen Indoor Air Quality Monitor designed to increase energy efficiency, as well as the health, comfort and productivity of building occupants within commercial buildings.

IAQPoint2 monitors three Indoor Air Quality parameters: carbon dioxide or volatile organic compounds (VOCs), temperature and humidity. It reduces the number of monitoring devices needed for an Indoor Air Quality monitoring solution from three to one, which in turn lowers the capital investment required to obtain a complete Indoor Air Quality monitoring solution.

Greening Buildings and Bottom Lines IAQPoint2 is a LEED-accredited device, a green building solution that can make a major contribution to boosting energy efficiency. Through its link to the building automation system, or BAS, via a communications protocol such as BACnet, IAQPoint2 activates the BAS on-demand, bringing just the right amount of fresh air into a building space.

Ventilation activation happens only when preset threshold levels in gas concentration are reached. When air within the building space returns to desirable levels, fans shut off. By using demand-controlled ventilation, IAQPoint2 helps avoid the common problems of either under-ventilating a building space, which leads to poor indoor air quality, or over-ventilating a building space, which increases the building’s operating costs. IAQPoint2’s on-demand ventilation advantage helps a building’s entire ventilation system run more efficiently, extending HVAC component life and lowering building operating costs.

Touch to Simplify, Touch to Save, Touch to Do More The touchscreen interface is both simple and practical to use. It’s all about the power of touch. Contractors can touch the screen to simplify installation and perform maintenance tasks, including calibration. In fact, wall-mounting the unit is a simple two–step process, a feature that saves the contractor hours on the job. Multi-level password protection prevents unqualified people from tampering with the unit or performing specialized tasks such as calibration. Calibration, in fact, is infrequent; the CO2 sensor requires calibration every 3-5 years, and no calibration is required for the VOC sensor.

RFS: Trials, Trends and Tribulations

An update on the status of residential fire sprinkler fire systems in Canada. BY Mark Evans

T

he number of NFPA-13D compliant Residential Fire Sprinkler (RFS) systems being installed in single family homes in Canada is on the rise due to a growth in the number of jurisdictions that have mandated compulsory inclusion of RFS systems. However, up to this point mandatory requirements for RFS systems have come solely from local authorities as there are no compulsory regulations requiring RFS systems in any Provincial Building Code or in the National Building Code of Canada.

Established by the National Research Council of Canada (NRC), the Canadian Commission on Building and Fire Codes (CCBFC) develops and maintains Canada's six model construction and fire codes. The Commission formally approves all model code documents and technical revisions prior to publication by the NRC. It receives policy advice from the Provincial/Territorial Policy Advisory Committee on Codes which is made up of representatives from the provincial and territorial ministries responsible for building, plumbing and fire safety regulation. Changes 72

HPAC | MARCH 2013

on a national level would be influenced by the position and recommendations of the CCBFC. Inclusion in the National Building and Fire Codes would be an important step forward as these are the model Codes that largely determine the requirements of Provincial and local Codes across the country.

In the CHBA Report section of the November/December 2012 issue of Home Builder Magazine, there is reference to a 2010 report commissioned by the Canadian Code Centre wherein it was determined that the “cost/benefit equation for mandatory RFS systems was prohibitive.” According to the article, “The report came under intense criticism from some in the fire safety community.” The article continues on to say the “A Task Group, which includes a builder (the Technical Research Committee Chair), was asked to review and comment on its findings. A report is expected for the CCBFC this February.” In fact, the task group has met once by teleconference and will meet again late this month (March 2013). No date has been set for delivery of the report. hpacmag.com

AT WHAT COST? The cost of RFS systems has long been a point of discussion and for some a significant barrier to widespread adoption.

According to a 2008 study entitled “Home Fire Sprinkler Cost Assessment” prepared by Newport Partners for the National Fire Protection Association’s (NFPA) Fire Protection Research Foundation, the costs per square foot ranged from a low of $.38 to a high of $3.66 with the average being $1.61 per square foot. The study included data from Pitt Meadows, BC where the average installed cost of the homes included in the study was $1.23 per square foot for standalone systems.

Further information on costs as found on the web site of the Canadian Automatic Sprinkler Association (CASA) shows that “Nationally, on average, home fire sprinkler systems add 1 per cent to 1.5 per cent of the total building cost in new construction." In March 2000, City of Surrey (BC) fire chief Len Garis presented to the Fire Department Instructors Conference in Indianapolis, IN. His abstract paper from these proceedings, entitled The Impact of Residential Automatic Fire Sprinklers on Public Fire Protection, details many things, among them the cost of installation in several communities in British Columbia.

The information in this paper comes from the Fire Chiefs Association of British Columbia who surveyed the cost of installing sprinklers in a few of its member municipalities. The average price was $1.16 per square foot (see Figure 1).

Assuming the average single-family dwelling is 2500 square feet, the cost would be $2,900. This demonstrates an installed cost element consistent with other sources.

However, part of the reason for the rise in the number of RFS system installations may be driven by capitulation rather than pure choice. As previously mentioned, many jurisdictions throughout North America, such as the City of Scottsdale, AZ (January 1986) and the City of Vancouver, BC (April 1990) have adopted local bylaw amendments that make RFS systems mandatory in new single family construction.

The benefits that accrued to these early adopters have motivated others to do the same, including the City of Pitt Meadows (July 1996) and many others in the Greater Vancouver area. Reasons for this include: Capital Cost Deferrals- By mandating sprinklers, local authorities may be able to forestall investments in infrastructure. In 1997, assistant fire chief Jim Scott- Rural/Metro Fire Department (Scottsdale) outlined some of the cost benefits to the City of Scottsdale in his paper: Saving Lives, Saving Money, Automatic Sprinklers - A 10 Year Study. The paper explains, “When ordinance 1709 was ready to be presented to the Scottsdale City Council, the primary focus and impact identified not only the life saving factors, but, the economic benefits that could be expected for the approximately 100 square miles of the city still essentially undeveloped.

Estimates for the infrastructure costs were based on the curhpacmag.com

rent city master plan and showed that substantial savings were possible. The major impact was projected at $7.5 million in infrastructure savings for the water distribution system. Additionally, it was anticipated that the sprinkler ordinance would result in the reduction in size or elimination of at least three fire stations at a savings of $6 million in initial capital costs and annual savings of over $1 million. The final determination identified that the cost of requiring this type of comprehensive fire protection was minimal compared to the life safety, emergency resource management, and property conservation results that would be achieved.”

Annual Cost Reduction - When homes in a community are sprinkled the annual cost of fire protection services is lower as outlined in Chief Garis’ paper. “Even with the cost of sprinklers, the annual Pitt Meadows’ cost of $37.50 per capita is still well below the average for the region and for the Province.

The total Pitt Meadows cost of $37.50 is $76.50 less than the regional district average of $114 per capita.

Likewise, the total Pitt Meadows cost of $37.50 is $26.50 lower than the provincial average of $64. To restate, even though Pitt Meadows homeowners have to install sprinkler systems, each resident still saves between $26.50 and $76.50 in fire protection costs annually. These per capita savings add up to significant resources at a Municipal level.

By multiplying the per capita savings by a population of 14 500, it is apparent that the District of Pitt Meadows saves between $380,000 and $1.1 million each year by requiring sprinklers.”

These are some of the compelling reasons, but what would motivate a developer to include RFS systems in a new project? In the appendix section 4 (A9) of Scottsdale’s Ordinance 1709 there is a benefit summary that lists reasons that are even more significant: Increased development density – There are trade-offs made here between the developer and the local jurisdiction.

Sprinkled buildings often allow for reduced fire department access to building sides, they may allow for narrower streets, fewer parking restrictions (and dedicated parking spaces), longer cul-de-sacs, reduced number of fire hydrants, etc.

Further, when you consider that the builder has discretion over the disposition of any cost savings, and the cost of the RFS will accrue to the homebuyer as part of the home price, RFS systems can significantly increase the profitability of a given development.

MARCH 2013 | HPAC

< Plumbing MOTIVATING FACTORS Finally, what motivates a potential homeowner to want a sprinkled home? Like the other stakeholders, part of the answer is for financial reasons. The web site of the US Fire Administration (FEMA - Department of Homeland Security) promotes the availability of insurance discounts to homeowners; “Insurance from home underwriters will vary depending on type of coverage. The discounts now range from five to 15 per cent, with a projected increase in available discounts."

Further, if the developer can save money in services and fees, and can build to higher densities, this may be reflected in lower purchase prices for homes within the development (or result in the homebuyer getting more home for the money).

Life safety would also be a prime motivator for families with small children, members who are infirm or have a physical challenge, or for seniors with limited mobility. By slowing down the fire and notifying family members the presence of a fire, the combination of smoke detectors and an RFS system can provide valuable time to exit the building that likely would not possible in the absence of this combination of systems. Further information from CASA on fire safety in Canada supports inclusion of RFS systems: • Nationwide, more than 300 people die in fires each year.

• Fire sprinklers save lives, reduce property loss and can even help cut homeowner insurance premiums.

• Installing both smoke alarms and a fire sprinkler system reduces the risk of death in a home fire by 82 per cent, relative to having neither.

Whom (and what) governs the design and installation of RFS systems? In most cases it is the local jurisdiction having authority that reviews the design as part of the permit application and approvals process. RFS system installations are generally undertaken in accordance with (and governed by) the design guidelines as developed by the National Fire Protection Association, specifically the NFPA 13-D Guidelines.

Originally developed in 1980, the NFPA 13-D Standard has evolved as new construction products and practices for installation have entered the residential construction market.

TYPES OF SYSTEMS A wet alarm system is as the name implies full of water, while the dry-pipe system is charged with air and would be employed in circumstances where the system may be subject to very cold temperatures and freezing conditions. In the past, a residential system installation would have been limited to a stand-alone wet system, as dry-pipe systems are typically not suitable in the residential context. However a new voice is now being heard as part of this discussion.

In 1985 the NFPA amended the NFPA 13-D guidelines allowing for a new variation of the standard wet alarm system, 74

this being the multipurpose system. The principal behind this design application is quite ingenious; it combines the RFS system into the home's potable water distribution system.

On May 12, 1993 the City of Vancouver adopted a modified “flow through” hybrid design version of the stand-alone system; including an element of the multipurpose system.

According to David Killey, manager of Fire Busters Inc., an RFS installer in Delta, BC, there are two principle benefits to be gained from this design. One would be the elimination of the backflow prevention device separating most dedicated fire protection systems from the potable water supply. This then also eliminates the annual testing and certification requirements that many jurisdictions have in place to ensure the performance of testable devices.

If such service was required, Killey indicated that, “For Vancouver homes equipped with a testable device, the going rate today is $100 for a DCVA test and full inspection of the sprinkler system." The other benefit is related to system function, "If the plumbing system does not provide running water, this will not go unnoticed. Thus, system function would be better ensured and failures relating to lack of water (ie: closed supply valves) should be a thing of the past.”

Other proponents of this approach offer other possible benefits, including the elimination of a dedicated water service and meter set for the fire protection system (not required in all jurisdictions).

According to Killey, “There is a proposal to include RFS systems as a mandatory requirement in the National Building Code and Fire Code in the pending revision in 2015.”

So, what of the RFS system trend? The industry is watching this very closely. As more jurisdictions choose to mandate RFS systems, both opportunity and competition in this market sector will grow. <> During the course of his career in the mechanical industry Mark Evans has worked in the wholesaler and manufacturer sectors in sales and marketing positions.

10 Things You Need To Know About How Customers Use Smartphones

BY John Carroll

T

en years ago, those select people who carried a cell phone did so mostly for making and taking telephone calls. How primitive we were. Now flash forward to recent years and it seems that almost everyone has a smartphone and they are doing much, much more with it than calling home to see if there is enough milk in the fridge.

Based on our research, here are 10 things you need to know about how your customers are using their smartphones. The list includes points that may prove invaluable to your future marketing efforts.

10

Consumers are using their smartphones to create lists â&#x20AC;&#x201C; grocery lists, to-do lists, wish lists, bucket lists. Whatever list it is, they are on their devices, building and sharing lists, taking photos and gathering information, and are keenly working to make things happen.

Sometimes, they are just passing the time. Maybe while waiting in line, or for an appointment, they are using their smartphones to kill some time by looking through social networking sites, playing games, listening to music, view texts or e-mails, read product reviews, or possibly to complain about waiting.

They are researching everything. Whether in a store, at an event, or a business meeting, they are pulling out their smartphones to find out anything and everything possible about the products, places and people they encounter.

Location, location, location. Consumers are using their smartphones to let friends know where they are by checking in on various social networking sites â&#x20AC;&#x201C; be it a concert, the office, a restaurant or the mall.

They are using smartphones to get discounts, deals and coupons. The increasing popularity of mobile coupons is no coincidence.

5

They are brand hunting. Consumers are using their smartphones to find you, where your product/service is available, the quickest/easiest way to get their hands on it, and what others are saying about it.

4

More and more consumers are making mobile payments on their smartphones. The technology is there and consumers are adapting.

3

More consumers are storing their loyalty and membership cards on their smartphones or using company apps to help them do so.

2

They are doing even more research. But in this case, the consumers are using their smartphones to research products and brands â&#x20AC;&#x201C; checking and sharing reviews and getting input from their peers on their thoughts and experiences.

1

Consumers are using their smartphones to talk about you. And they are not holding back. Whether it is to their own social network, responding to your surveys, or contributing to a review site, consumers are giving loads and loads of feedback and commentary on the products and services they are shelling out money for. <> John Carroll is the global head of clients for Ipsos Loyalty where he serves clients around the world and across numerous industries in the areas of customer strategy, innovation and performance improvement.
