TAMING THE BEAST By

all accounts our industry is on

an upswing. AHR Expo reported good numbers, both in terms of exhibitors and visitors. CMX/CIPHEX is reporting a flurry of activity in the final lead up to the show. The shock of the economic crisis is over and businesses and individuals are learning to live with the resultant uncertainty. The question is how long will that uncertainty remain a factor? It will not be a speedy recovery according to Peter G. Hall, Export Development Canada vice-president and chief economist, who believes it is the lagging indicators we need to be aware of. “They are the final waves that recessions send crashing into an economy, and depending on their timing, can wreak havoc with nascent recovery,” noted Hall in his February 24, 2010 weekly commentary. The weakening of the commercial construction sector is a key indicator cited by Hall. “Long lead-times ensure that recessions are always well underway before the commercial

construction sector reacts. In Canada’s last two recessions, private non-residential construction saw some of its largest declines up to eight quarters after the technical recession ended,” he said. “U.S. investment in non-residential structures saw steep declines persist for a year or more after the 1981-82 and 1990-91 recessions, and the sector sustained six successive scathing declines in the 2001 economic slowdown. In all cases, declines were still occurring as robust recovery kicked in.” The current recession is no different but continued drops in this segment of the economy are unlikely to directly derail recovery, contended Hall. Reassuring words as we continue to hope that the leading indicators tame the lagging indicators (and the unease) over the next few months. In the interim, the enthusiasm around and participation in events such as CMX/CIPHEX, remain a reasonable barometer of the industry's health. Editor

For flexible placement and integration with interior décor, the thermostats can mount on a wall or sit on a stand on tables or shelves. An ideal solution for retrofits and remodels, the Zoning System installs easily and is intuitive to set up. It offers competitive savings, beating installation costs once one base unit controls three or more zones or even on a traditional five zone install on hardware alone – not to mention additional labour savings. Offering significantly less wiring from remote to actuator location – relocation of thermostats is also made easy.

The Zoning System includes a radio-controlled base unit, an interface module and wireless thermostats. The base unit uses a special FCC-approved radio protocol to ensure consistent signal quality. Connecting up to 12 wireless thermostats, the unit can also accommodate and control up to 14 thermal actuators. Additional base units are also able to link together for larger installations.

AIR CONDITIONING SETBACK BYLAW UNREALISTIC

A proposed residential setback zoning bylaw for residential air conditioning units in the City of Toronto has raised industry concern. Most units in the city are installed on the ground and the proposed requirement of 1.5 m clearance from the side property lines is thought to be onerous. In the comments submitted to the city's zoning committee, the Heating, Refrigeration and Air Conditioning Institute (HRAI) noted that that there are very few homes in Toronto that have enough property to allow 1.5 m between the outermost edge of the unit and the property line. HRAI added, "taking into account the typical width of the outdoor portion of the air conditioner, the house would have to be more than six metres from the property line to allow for this requirement to be met. This increase in distance from 0.8 m is simply not realistic in Toronto." The HRAI submission recognized that Toronto has a separate noise bylaw that includes requirements for residential air conditioning and because of this, the association does not understand why the proposed bylaw includes such excessive setback requirements. HRAI recommended that the sections in question contain a minimum side yard and corner lot setback of 0.9 m. This will ensure new and replacement air conditioning systems can be offered to homeowners in Toronto. For more information, contact Warren Heeley at 800-267-2231 ext. 227 or e-mail warren.heeley@hrai.ca.

GREEN ROOFS RULE IN TORONTO The City of Toronto Green Roof Bylaw was adopted by Toronto City Council on May 26, 2009 and went into effect for all new building permit applications made after January 31, 2010 (residential, commercial and institutional) and January 31, 2011 for all new industrial development. A green roof is required for development above 2,000 m2 gross floor area with the graduated coverage requirement ranging from 20-60 per cent of the available roof space (excluding industrial). The coverage requirement for industrial buildings, which starts in 2011, is equal to 10 per cent of the available roof space up to a maximum of 2,000 m2. The city is also offering incentives through the EcoRoof Incentive Programs to retrofit existing buildings with a cool or green roof. toronto.ca/greenroofs

BRIGHT LIGHT ON HORIZON WITH RECORD-BREAKING ATTENDANCE The 2010 AHR Expo in Orlando, FL exceeded pre-show attendance estimates with nearly 45,000 registered attendees. The 28,582 registered visitors represented a nearly eight per cent increase from the 2005 AHR Expo in Orlando and set a record for southeast HVAC/R shows. Visitors came from 120 countries to see products on display from 1,823 exhibiting companies. More than 200 companies were firsttime exhibitors at AHR Expo.

NEXT GENERATION HOUSING INITIATIVES Natural Resources Canada (NRCan), together with stakeholders, is working to set the direction for the next generation of energy efficiency programs. This will include a next generation EnerGuide Rating System (ERS) to accommodate advances in both existing and new housing technologies (including net zero homes), and the growing needs of the many stakeholders and partners involved with ERS. The target is to have the renewed system in place by April of next year. With the introduction of provincial building codes requiring an EnerGuide rating for new houses at or near 80, the goal is to develop the most effective next generation energy rating system for new and existing houses that is supported by the best tools and is acceptable to and recognized by all stakeholders. continued on page 12

ASHRAE Publishes Green Standard A standard for the design of high-performance green buildings has been published by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), in conjunction with the Illuminating Engineering Society of North America (IES) and the U.S. Green Building Council (USGBC). Standard 189.1, Standard for the Design of HighPerformance, Green Buildings Except Low-Rise Residential Buildings, covers everything from site location to energy

use to recycling, and covers key topic areas similar to green building rating systems. A readable copy and more information is available at ashrae.org/greenstandard.

WHAT WERE THEY THINKING? This is truly a case of a commercial washroom design gone amuck. Located in a very large office building, this restroom could easily carry a couple of segments of You're On Candid Camera. In fact, it has become sport for the experienced user of the facilities to watch as perplexed visitors eyeball the situation, then run their hands under, around and over the mirrors, vanities and sinks, still frequently unsuccessful in finding the soap. Some enterprising and thoughtful person later removed the sticker provided for the no-touch paper towel dispenser to assist those who cannot find the soap. But, you must hit the magic spot, which is about the size of a dime to get your dose of foamy soap. Veterans now turn their attention to the novices who can't figure out how to operate the paper towel dispenser.

2010 Venues On The Podium The International Media Centre at Robson Square in Vancouver, BC was the host venue for the recent Canada Green Building Council (CaGBC) awards ceremony. The ceremony and press conference highlighted the achievements of the green builders and innovators in reaching for LEED (Leadership in Energy and Environmental Design) status for over 31 Vancouver 2010 Olympic and Paralympic venues. In partnership with BC Hydro, CaGBC honoured the Province of British Columbia, VANOC, the cities of Vancouver, Richmond and the Resort Municipality of Whistler for their global leadership in sustainability. "By committing to building venues and Athletes villages to the LEED Canada building rating system, the 2010 Winter Olympic and Paralympic Games have created an environmental legacy which will benefit British Columbians and Canadians for years to come," said Thomas Mueller,

With its green roof system and solar array, the Southeast False Creek Community Centre rooftop is just one example of the sustainable features in construction of games facilities and venues.

CaGBC president and CEO. Bev Van Ruyven, acting president and CEO, BC Hydro noted that, "The conservation measures implemented at a number of these venues are expected to save more than 18 gigawatt hours of electricity annually, enough to power more than 1,600 homes for an entire year.” New facilities like the Richmond Olympic Oval are demonstrating savings of 878,000 kWh or 15 per cent and most impressively the Vancouver Olympic Village is designed for a reduction in energy use by 53 per cent or savings of 11,500,000 kWh. "These facilities not only made improvements in energy performance but a range of environmental measures including water efficiency, healthy materials and better indoor air quality. They demonstrate the growing commitment and expertise in Canada to constructing environmentally responsible buildings," added Mueller.

Halocarbon Issues Top Of Agenda Warren Heeley, president of the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI) met with members of the Commercial Chemicals Branch of Environment Canada in Ottawa recently to discuss halocarbon issues.

MSN Heeley reiterated the association’s commitment to the proposed federal EPR regulations and the positive impact these regulations will have on the Refrigerant Management Canada (RMC) program. Environment Canada confirmed that the EPR regulations are a priority based on the EPR resolution that the Canadian Council of Ministers of the Environment agreed to in 2009. Environment Canada also confirmed that they are looking at and participating in the international progress on HFC controls, including legislation being considered in the U.S. The international and U.S. direction will impact the approach Canada will be taking on HFCs. Concerning HCFC regulations, Environment Canada confirmed that Canada will be taking the same approach as the U.S. on TX valves that contain small amounts of R22 imported after January 1, 2010. These components can continue to be imported into Canada as service parts until December 31, 2014. Environment Canada will be sending out an interpretation on this.

Environment Canada also confirmed that there may be an opportunity under the federal ODS regulations to include a requirement mandating refillable containers for all halocarbons imported into Canada. This is an issue HRAI has been discussing with Environment Canada for a number of years to ensure a level playing field in the market for all halo­carbon refrigerants manufacturers and distributors.

Practice What You Preach... How Green Do You Want to Be? BY JOHN SIEGENTHALER

A

few months ago I attended a session on solar water heating at an international conference on solar energy use. The conference had record attendance, and the room where the session took place was packed with upwards of 100 people, people who made time in their schedules and paid good money to be there.

HOW GREEN ARE YOU?

If you design, sell, or install energy efficient equipment, you should make a diligent effort to use some or all of this hardware in your own home and/or place of business. The fact that you personally use what you sell is also a huge confidence booster for most consumers. Want proof? How often – after describing multiple options to a potential customer – have they responded: “if this was your house, what would you use?” As a green professional you also have the responsibility to teach your customers how to operate the systems you provide to maximize their benefits. Challenge them to use these systems in ways that optimizes their benefits. Keep in mind that this sometimes involves compromises in what most North Americans are accustomed to. For example, the system shown in Figure 1 is a solar thermal combisystem. It uses a combination of solar energy and conventional (gas) energy to supply a home with heating and hot water.

A speaker began the session by asking how many in the audience had a solar water heating system installed on their home. By a show of hands I estimated no more than 10 per cent of the people in that room lived with solar water heating. Granted, some of those present were new to the subject and wanted to get more involved. Some may also have lived in rented quarters where such a commitment was not theirs to make. On the other hand, modern solar domestic water heating systems have been available in North American for over three decades. Government–based financial incentives for such systems have also FIGURE 1 been in place for several years. Fuel prices did not just become unstable last year. The speaker’s implication was that many of those present have had ample opportunity to demonstrate what they advocate and in many cases, what they hope to profit from. In short – to practice what you preach. Over the years I’ve had opportunity to do this by installing a wide range of what are now considered green energy systems in my home. They include solar energy systems (active thermal, passive thermal and photovoltaic), a ground source heat pump, a heat recovery ventilator and a wood– burning stove. Living with these systems has exposed their benefits as well as their weaknesses in ways I would never have discovered by reading through literature, surfing websites, or making occasional site visits. The knowledge gained from this experience has been invaluable in influencing how I currently design systems and what I write about. 20

SOLAR THERMAL COMBISYSTEM

HPACMAG.COM


An external, stainless steel brazed plate heat exchanger is used to transfer heat from the antifreeze–filled collector circuit to system water in the storage tank. A second stainless steel brazed plate heat exchanger is used to separate domestic water from system water. It is mounted adjacent to the storage tank and has its own circulator (P3), which moves water from the tank through the hot side of the heat exchanger. Circulator (P3) is turned on by a flow switch, which closes whenever there is a domestic hot water demand of 0.5 gpm or more. When operating, (P3) only draws about 10 watts of electrical power. Cold domestic water is instantly heated as it flows through the brazed plate heat exchanger.

A DEEPER SHADE OF GREEN The standard way to operate this system would be to maintain the top of the storage tank at or above a temperature that assures domestic hot water is always available. With a properly sized heat exchanger, that temperature would likely be in the range of 125F to 130F. If the sun has been out, the tank may be at or above this temperature during the afternoon and evening. If not, the boiler operates as necessary to maintain the necessary temperature. Most North Americans would assume that domestic hot water should be available 24/7, whenever they choose to open the tap. Herein lies a great opportunity to alter conventional thinking in a way that would eventually have a profound impact on how our North American culture uses energy. This system could have another operating mode, one that is in effect when normal domestic hot water service is not deemed necessary, lets say from 11:00 p.m. to 5:00 a.m. During this time, the temperature at the top of the tank is maintained based on an outdoor reset curve appropriate for the low temperature space heating system. This temperature will usucontinued on page 24 hpacmag.com

Green in the mechanical sense The word “green” is now unavoidable during an average day in North America.You are likely to first read this word on the front page of the morning newspaper. Later, you will see it repeatedly used in trade journals, as well as consumer magazines.That afternoon you will notice it on several products or advertisements at the local store. By the end of the day chances are you will hear it used as the focus of a new government job incentive program. Our culture now interprets being green as having achieved a heightened sense of consciousness about how we should relate to and protect our environment. We have been relentlessly conditioned to view green as something we should aspire to, a never– ending quest to minimize any adverse impact we may impose on our planet. Many people now view themselves as needing more of whatever green happens to mean to them. Going green can be anything from installing a bike rack at a public building, to using glass mulch made from crushed bottles for landscaping, to adding insulation to one’s attic.The word green has become an envelope for older terms such as reduce, conserve and recycle. Going green also describes actions such as increased use of renewable energy, planting grass and flowers on your roof, or bringing your own bags to the grocery store. Within the context of mechanical systems I see “green” categorized as: Low Energy Use: • High thermal efficiency • High distribution efficiency • Low or no standby heat loss • Interior comfort that reduces occupant induced wasted energy • Appropriate use of renewable energy Long Equipment Life: • Minimal maintenance and simple serving • Reduces travel to/from installation site • Reduced installation energy (electrical use, temporary heat, soldering fuel) Reduces use of expendables Less soldering flux Less VOC emissions Less stripped wire insulation Less unusable lengths of tubing Less packaging materials to dispose of Less clean up materials Less need for replacement components (filters, nozzles) Environmental Stewardship: • Low emissions • Use of recyclable materials march 2010 | HPAC

“Perhaps you are worried that customers would complain about having to push a button and wait five to 10 minutes if they want to shower in the middle of the night.” ally be lower than that required for normal domestic hot water delivery, especially during spring and fall. During this reduced temperature mode the system retains some ability to heat domestic water, but not necessarily to normal delivery temperature. If the occupant has to take a shower at say 3:00 a.m. and there was insufficient solar gain during the previous day, a temporary override button – one that could be placed on the bathroom wall – could fire the boiler in a time–limited priority mode to quickly boost upper tank temperature and restore normal hot water delivery temperature. Sufficient hot water would be produced for the shower provided the occupant was willing to wait five to 10 minutes. That is the only compromise. The reduced temperature mode allows greater use of solar energy input to the tank during the previous day. It also improves the efficiency of the modulating/condensing boiler when operated in that mode. The top of the tank would be increased back to normal DHW delivery mode before the typical morning demand for domestic hot water. Following this high demand period the system could revert to reduced temperature mode to improve collector efficiency during the midday period. Adaptive controls could even monitor domestic hot water usage trends and adjust tank temperatures to optimize solar utilization and provide high satisfaction with domestic hot water delivery. Perhaps you are worried that customers would complain about having to push a button and wait five to 10 minutes

if they want to shower in the middle of the night. Herein lies the opportunity to challenge them about their greenness. Rather than complaining about a very minimal compromise, those who really want to be green should embrace such a scheme once they understand the benefits. This is a way for people who profess a green lifestyle to demonstrate their commitment and influence others about appropriate use of resources. Eventually, the North American cultural mindset of “convenience at any cost,” such as hot water standing ready for instant use in a 3:00 a.m. shower, could be changed to champion responsible energy use with minimal compromise. As I see it, hydronic heating has always been a greener choice compared to other heating methods. Emerging technology and modified use patterns such as described above, could paint hydronics technology a new shade of deep green. John Siegenthaler, P.E. is the author of Modern Hydronic Heating.

Sizing Is Everything This year we will see the release of an updated version of the National Plumbing Code (NPC). Considering that water pipe sizing is getting a revamp (see HPAC January/February p. 22), I thought it would be worthwhile reviewing this topic. I am of the opinion that water pipe sizing does not get the attention it deserves. BY STEVE GOLDIE

I

n any plumbing system there are three major components: the plumbing fixtures; the water lines bringing potable water to the fixtures; and drainage system that takes the waste water away from the fixtures. There are a multitude of different types of plumbing fixtures, and many different types of applications and usages. It would seem reasonable to assume that the rules pertaining to the piping on the supply side of any fixture would be as varied and complex as those pertaining to the piping used to drain the waste away from these same fixtures. As

with many assumptions, this one is quite simply wrong for a couple of simple reasons. The first one is obvious really. What goes in is always just water -- hot, cold or both, but always clean, potable water. What comes out the other end on the other hand, well that is another matter all together. The other reason is pressure. The supply side of the plumbing piping system is a pressurized system, whereas the drainage side relies on gravity. This is reflected in the code, which very specifically prescribes pipe sizing and continued on page 30

Undersized supply lines can result in very unhappy customers, particularly if it takes hours to fill the fancy new bathtub.

practice in order to ensure properly functioning drain and vent systems, whereas much of the sizing of the supply system is left up to the individual installer or designer. The code specifies minimum supply pipe size for fixtures, the overwhelming majority of which are all the same: ½” (notable and rare exceptions being direct flush urinal and toilet valves at ¾” and 1” respectively). Minimum flow pressures that need to be maintained at fixtures are also specified: 50 Kpa for just about everything, again with the exception of direct flush valves, which need to have a minimum of 100Kpa. Other than establishing that no water service pipe can be less than ¾” and that from the meter to the branch for a hot water tank must also be a minimum of ¾”, there is no other specific water pipe size prescribed. The onus is on the designer or installer to size the system in order to allow for the system to operate at “peak demand flow.” System static pressures vary, but are typically in the

the size of the connection. Large Roman bathtub fillers are a good example of this. Most Roman bathtub fillers have valve connection sizes of ½”, but if you connect them via ½” hot and cold lines all the way from the basement, 50’ away from the hot water tank, chances are your customer won’t be happy with how long it will take to fill the tub. You can blame the “poor water pressure” if you like, but the real reason would be undersized supply lines. Run ¾” lines instead, using ½” for just the last couple of feet at the connection and you will see a dramatic increase in performance, a faster tub fill and a much happier customer. Increasing the size of the supply line from ½” to ¾” has no affect on “static” water pressure. Static pressure is the pressure in the system when no taps are open and the water is not moving. Once the tap is opened, the flowing water creates friction on the pipe walls. This friction force in effect “uses up” some of the pressure

“…the size and accumulated length of a water line has a much greater affect on the flow at pressure than the size of the connection.” range of 450 to 500 Kpa, which allows for a certain amount of flexibility in pipe sizing. Sizing charts and guidelines included in the 2010 NPC will help designers and installers to properly size water lines, but again will stop short of actually prescribing actual minimum pipe sizes beyond what already exists. This is not to say that proper sizing is not important, but rather, the pertinent facts can be reduced down to some fairly basic and universal principles that can be applied to virtually every application. Pressurized systems allow us to move significant amounts of water through relatively small pipes, but there are always limitations. One of the mistakes I often see with regard to pipe sizing occurs when installers size their water lines according to connection size rather than flow requirement. We see this very often relating to pipe sizing in hydronic heating systems, but the same physics apply in water distribution systems. Many people believe that if a fixture or component has a connection size of ½” for example, then there is no advantage in running anything other than a ½” line to that fixture or component. In reality, the size and accumulated length of a water line has a much greater affect on the flow at pressure than 30

as the water moves through the line. The smaller the line and the longer the run, the more pressure is used getting from the source to the tap, and the lower the flow rate. A larger pipe size for the longest section of the run means lower friction losses and more pressure available to move the water faster, resulting in larger flow rates. The two most common complaints I hear with regards to plumbing systems are too much noise and too little pressure. In truth, both of these complaints are often symptoms of the same problem, undersized supply water pipe size. When we try to push too much water, too fast through water lines that are too small for the task, this is the kind of result we can expect. Hopefully the NPC 2010 will help eliminate any of the confusion that has resulted in these kinds of mistakes.

Enhance System Performance BY MIKE MILLER

Control capabilities

Some outdoor reset controls allow the starting water temperature to be changed differently from the starting outdoor temperature in order to allow fine-tuning of the heating curve by manipulating its slope. Instead of entering a reset ratio into a controller, some outdoor reset controls ask you for the specific temperatures that are used in the formula right in the setup and then provide the right reset ratio automatically.

very modern hydronic heating system should be controlled by smart technology, whether it already comes with a heat source or if it is an external controller that is added to the system. At the very least systems should have weather responsive water temperature control. In our industry, this is most often referred to as outdoor reset. In simplistic terms, outdoor reset controls adjust the supply water temperature provided for a heating system based on outdoor air temperature (see Figure 1). The heating load of a building is directly related to outdoor air temperature, where the heat output of a heat emitter is directly related to water temperature it is provided with. For example, a building has its heat loss assessed based on the type of building construction and the harshest climate it is located in, while still being able to maintain a comfortable indoor air temperature, usually near 70F. Let’s look at an example. If you are in an area where the coldest day of the year (outdoor design temperature) would be -30F, you would still want to maintain a desired indoor air temperature (indoor design or room temperature) of 70F. If radiant floor heating was the heat emitter, a heat loss conducted on the building may suggest you need to deliver 120F water to the system on the coldest day of the year to maintain the desired indoor air temperature. Now, even though we live in Canada, luckily, not every day is at -30F. As the outdoor temperature increases

(warmer), the heat loss of the building is reduced. The most efficient radiant floor heating system would provide continuous flow while the water temperature is adjusted. An outdoor reset control would then lower the water temperature supplied based on a calculated reset ratio as the outdoor temperature rises. The reset ratio can be calculated with Formula 1.

FORMULA 1 Design Supply Water Temp. – Indoor Design Temp. Indoor Design Temp. – Outdoor Design Temp. Design Supply Water Temp. – Indoor Design Temp.

temperature will increase by 0.5F for every 1F the outdoor temperature drops. Target Water Temp. = 70F + (70F – 10F × 0.5) = 100F To calculate a target water temperature based on a current outdoor temperature, you would use Formula 2. hpacmag.com

Without outdoor reset, in order to eliminate overheating when the heat loss of the building is reduced due to higher outdoor temperatures, the flow to the building or zones would have to be cycled On and Off if the water temperature provided was constant. The warmer it gets outside, naturally, the longer the Off times and the shorter the On times would be. The usual result is temperature swings in the space, and depending on heat emitter, expansion noises due to warming and cooling (expansion and contraction) of the piping and/or components used. Installing a heating system without outdoor reset is comparable to making a car with nothing more than an On/Off switch, rather than a gas pedal and accelerator.

ADDITIONAL BENEFITS While outdoor reset is the easiest to implement and creates energy savings, indoor temperature feedback can gain additional savings. Indoor feedback allows a control to fine tune its outdoor reset curve (water temperature being supplied) based on indoor condition as well. Indoor feedback gathers internal heat gains from lighting, solar gain through windows, stoves, fireplaces, people and so on. It can also gather added losses to a building related to additional loading, such as cold wind storms on the exterior of a building. The end result will be that the outdoor reset control combined with indoor feedback will always run your system at the lowest possible water temperature and continuous flow to satisfy the desired indoor temperature at any given time. Most often if the building is tight, indoor feedback control systems run at lower temperatures than with outdoor reset alone. Indoor feedback to a system can be gained by installing an indoor air sensor on a single zone system in the common area of the building. More sophisticated conhpacmag.com

Figure 2

trols utilize supply and return water temperature sensors (see Figure 2), installed on the distribution piping to the building combined with a control algorithm, to account for internal and external heat gains and losses, but adjusting the water temperature to maintain a constant deltaT (temperature difference). In multi-zone systems, a more complex and fully integrated control system that utilizes communicating thermostats for each zone can provide indoor feedback based on the hardest to heat zone in the building at any given time. This type of system considers every zone of the building at any elevation or exposure. As the sun travels around the building throughout the day, the highest heat load of the building may shift with it. For example: In the morning – west of the building is in the shade and the east may be in the sun, thus experiencing solar heat gain. In the evening, this could be opposite. Once you are using a sophisticated control system with multi-zone indoor feedback, it is easy to integrate air based heating and cooling, and to harmonize the control of a full building. This subject will be explored in an upcoming article. Mike Miller is a controls specialist with experience in the manufacturing, distribution and contracting sectors of the industry.

An ‘Exhumination’ of Earth Tube Heat Exchangers The earth tube heat exchanger (ETHE) is an energy conservation system from the past that, along with other specialized energy systems which desperately need professional engineering, is often treated as another modern experiment du jour. BY ROBERT BEAN

34

HPAC | MARCH 2010

What you have are the results of good intentions gone bad ( maybe I could make millions selling this DVD on late night TV against Girls Gone Wild). Perhaps all of this is a little melodramatic but I did write “worst case” scenario. So what is the upside to the downside? There is none (and here is the caveat) unless you explicitly understand that the ETHE is a H-E-A-T exchanger as I have emphasized already. As history has revealed, most weekend engineers have a propensity to confuse heat with indoor environmental quality (IEQ). Now that we have the grit and grime out of the way, the upside to these low down systems is that they can be an altruistic and maybe even a practical way of shaving the peaks off heating and cooling loads on some projects in some climates. They can and do contribute to the global quest of reducing energy use by eliminating or at least reducing the need for compression and combustion to condition occupants and spaces. Of particular interest to those way out on the limb of renewable energy, is the use of solar chimneys to induce draft through the ETHE eliminating the need for power during daylight hours. These chimneys also offer the opportunity to generate electrical power with turbines.

A WORKABLE SOLUTION In order to specify a workable solution designers of ETHE systems should evaluate: Location: If the system is predominantly cooling you will want the collector in a permanently shaded area near a lake or river. If the system is predominately heating it should be located in a sunny area without some aquifer competing to steal away the heat. Intakes have to be located away from sources of pollutants. These include vehicle emissions, products of combustion from fire pits, lanterns, barbeques, boilers and furnaces, exhaust fumes from bath fans and continued on page 36 HPACMAG.COM

or the uninitiated, ETHEs are air to earth heat exchangers employed to shave the peaks off heating and cooling loads, thereby lowering combustion and compression needs. Outside air (of seasonal temperature) is drawn down into relatively constant earth temperatures at 1.5 m to 3 m below grade into a buried air duct installed in similar fashion to PEX pipe in a radiant slab…think 150 mm to 300 mm buried conduit placed in a serpentine or reverse return system. In the hot summer, the heat in the outdoor air is conducted along the buried exchanger to the earth resulting in cooler entering air temperatures into the building’s HVAC system and in the winter, heat from the ground is conducted into the cooler incoming air resulting in warmer air temperatures into the building’s HVAC system. That is as complicated as it gets for members of the society of experimenters but wait, there is more. ETHEs are not air quality control systems. Anyone making, designing or installing such a system would be illadvised to guarantee the quality of air being delivered to the indoor space. In the worst case scenario, the outside air might contain moisture and particulates, including mold spores, pollen, virus and bacteria, and smoke and debris from forest and field fires and the occasional volcano eruption. Add in some ozone ala shortwave radiation from the sun and products of combustion via the di and mon oxides of sulfur, nitrogen, hydrogen and carbon. Stir in some farm fresh herbicides or pesticides with odours from the compost pile, local dump or meat packing plant. Then pay for the electricity to run the fan that draws the smorgasbord under negative pressure into the buried duct work embedded in soils emitting radon and methane, condense the mix into condensate and let it ferment into a toxic soufflé…and the only thing left to do to yourself or client is to blow the entire recipe into the home.

dryer vents, or sources of odours, such as garbage bins, compost piles and sewer vents. Depth of pipe (temperature): Available shortwave radiation on the collector surface is directly related to the mode the system favours most with consideration for the depth of pipe and can typically be between 1.5 m to 3 m. A system that is designed predominately for cooling in an area without shading will need the pipes buried deeper than a system designed for heating in the same locale. Soil conductivity (heat transfer): I am disappointed at the papers and literature that promote the use of sand as the bedding material for ducts. Dry sand is the worst thing one would want in the process of conducting heat to and from buried ducts. Dense, wet and conductive (can you say moist compacted clay) is the trick. Duct material and tube connections: Options include concrete, metal, plastics – with or without conductive fins or antimicrobial agents. It is a case of equifinality (another way of saying there are many ways to skin a cat). The ducts cannot sag under loading. The connections have to be robust and of the highest quality as they and the ducts have to deal with ground moisture and soil gases. They must be of the most conductive material for the lowest cost with the least air flow resistance but offer the best characteristics against corrosion. For the cost evaluators I ask: What else is new? Temperatures, flow, velocity, diameter, friction, length, layout and drainage (the thermal to hydraulic part of the calculation): According to application engineers, velocities between 6m/s to 10m/s are typical. This means the diameter has to be picked based on flows and friction losses. To optimize designs based on the thermal and pressure requirements, using several shorter lengths in parallel in a reverse return arrangement can in some cases be better than a single longer serpentine loop or it may be more suitable to use a loop that follows the perimeter of the buildings foundation. Air entering the ground duct and the HVAC system will need

to be conditioned: This means it has to be suitable for inhalation by the occupants through the decontamination of particulates, moisture, odours, gases and biological concerns. Decontamination is a continuous process with both outdoor intake filters and indoor components and systems needing monitoring and maintenance. Energy analysis: The designer will need to evaluate the capital and operating costs of the system, including the electricity to run the fan and decontamination equipment to assure the energy used is lower than the cooling or heating power offered by the system. Researchers are reporting the ability to shave off 10 to 20C from heating and cooling loads with one source reporting COPs of 3.3 in cooling and 3.8 in heating. Building science issues: Depending on the type of system there could be issues with infiltration and short circuiting of the ground exchanger. It is necessary that both building and ducts are sealed tightly to prevent differential pressures across and within the home from interfering with the required differential pressures in the ETHE.

SHORT STROKES ETHEs are not new and have always been a good idea but given all the construction effort and IAQ concerns with them, one has to consider whether it might be better to place a sufficiently-sized glycol coil in the air handler and feed it from a closed geothermal earth loop. This takes care of the heat and IAQ issues. Until I can get my hands on some good comparisons between these two options, the jury will be out on the down in the ground ground to air exchangers.

Plumbing

Seeking A National Solution Stakeholders work toward standardized codes and standards training for plumbing inspectors. BY MARK EVANS

T

he Canadian Advisory Council on Plumbing (CACP) was formed in 1970 and consists of industry, all provincial and territorial chief plumbing inspectors, representation from the Standards Council of Canada, Accredited Certification Organizations, NRC and Health Canada. At the August 2006 meeting of CACP, the concept of standardized training for plumbing inspection officials was presented. From this a task force was struck, co-chaired by Ralph Suppa, president and general manager of the Canadian Institute of Plumbing and Heating (CIPH) and Jim Holt, team leader-building inspections, Halifax Regional Municipality. According to information from CIPH, the task force had a mandate to examine the issues and potential solutions to them. A questionnaire was circulated, which solicited input from all provinces and territories. At the September 26, 2008, meeting of the National Plumbing Inspectors Association, Suppa made a presentation that addressed the findings of the questionnaire. Many common threads were identified, including: »» Concerns regarding counterfeit products. »» The use of non-approved plumbing products in regard to applicable existing Standards. »» The quality of installations. »» Fragmentation of codes. »» National certification/training program for plumbing inspectors. »» Time pressures on plumbing inspectors in the field. »» Training on interpretation of Codes. With the questionnaire complete, the task force was expanded to include Gordon Jensen, representing the Plumbing Inspection Officials Association of BC and John Gunn of the Ontario Plumbing Inspectors Association (OPIA), as well as representatives from the Canadian Standards Association (CSA), CIPH and several regulator/members of CACP. In his presentation, Suppa noted that, “However, there is no comprehensive national program in place to support the industry. Identified issues, gaps in knowledge, and ability to interpret codes and standards are not regional in nature.

38

HPAC | March 2010

The development of a national program would provide jurisdictions with a foundation program to address these needs. Delivery of such programs could reside with training organizations in each region and elements customized, as necessary, to meet their specific context. “Also, as standards, regulations and codes are being harmonized, and labour barriers are relaxed, we believe that this training will help harmonize labour and provide a uniform labour mobility marketplace,” added Suppa. Fast forward to the September 22, 2009 meeting of the OPIA and a joint presentation by CIPH and CSA - “National Plumbing Inspectors Education and Training Program – Pilot Project.” The presentation outlined a process of consultation that culminates with the proposal for a pilot project providing education and training, the intent of which is to provide a “National solution that builds on existing body of work to support inspectors and provide for improved application of codes, standards, and regulatory requirements, and improves consistency and quality of inspections.” The proposal brief outlined the elements of this pilot program consisting of an: »» Interactive, self-paced, and modularized e-learning training program that can also be delivered in classroom setting. • Available in both official languages. • P  rogram would include: Initial self assessment test ~ F ive modules each with a self-check tests. Final evaluation. Linear and/or non-linear ability to move through program. Foundation national content with provincial deviations. Unlimited 24-7 access for a prescribed period. The proposed curriculum for this program was conceived during a three-day curriculum design workshop, which was hosted by CSA, April 1-3, 2009. According to the proposal brief, the workshop was attended by plumbing inspectors, educators and representatives from the building and manufacturing community from every region of Canada and from hpacmag.com


the United States. From this workshop a very detailed curriculum was developed and subsequently sent out to survey. This resulted in a proposed curriculum that will be used to guide the development of the education and training materials. In closing, the presentation outlined the next steps in this process as being a tender by CSA for the development of the content for the training program. Once the content has been written, it would be converted to an e-learning format that will be able to be deployed online or in a classroom setting for initial delivery in 2010. With its intent to provide consistency in the application of codes and standards between authorities having jurisdiction (AHJs) across the country, this initiative is one that should be lauded and supported by manufacturers and contractors alike. It builds on the intent of programs such as the Red Seal Program, which provide skills validation and proof of competency for installing contractors as they cross provincial boundaries to work outside their home jurisdiction. It is validation for the fact that with the emergence of performance-based codes, and the evolution of standards to keep pace with technological innovation, industry stakeholders are effectively represented by their constituent associations as they act in anticipation of the need to improve and keep pace with change; while in the pursuit of the enhancement of life safety, system performance and the opportunity for interprovincial commerce.

Hydronics

Coming Of Age A backgrounder on the referencing of CSA B214 in NBC 2010. BY RAMAN CHAUHAN

T

he development of a standard for hydronic heating systems was prompted by industry stakeholders who recognized the need to fill a serious void. Hydronic systems were being installed at an increased rate in smaller residential and commercial buildings while regulators and installers did not have a tool to deal with the design and approval of such systems. A technical committee at CSA had been created to work on a draft standard for hydronic heating systems. This standard was needed by the installers to guide them and by the regulators to provide them with an assurance of safety and of good installation practice. The standard was also needed to deal with installations that were being installed as combination hydronic space heating and water heating systems.

CONSENSUS STANDARD CSA undertook to develop a consensus standard with the hydronic industry. Once it was developed a request was made to reference it in Parts 6 and 9 of the National Building Code. When the completed standard was reviewed by the appropriate committees at the National Research Council (NRC) Codes Centre, which looks after the content of the NBC, the 2001 edition of the CSA-B214, “Installation Code for Hydronic Heating Systems” was found to be inappropriate for referencing in the 2005 NBC because the standard included: • Best practice requirements • Design requirements • Energy efficiency requirements • Administrative requirements In other words instead of being a standard for hydronic heating systems it had become a handbook for hydronic systems. This was not acceptable for a reference standard. A joint task group on hydronic heating initiated a review of the draft standard. Its purpose was to determine if the revised standard should be referenced in the 2010 NBC. This group reviewed the standard and suggested revisions to ensure that it was purely a standard for installing hydronic systems and not a handbook of hydronic systems. The reason for obtaining a reference was to fill a void as seen by 40

HPAC | March 2010

the authorities having jurisdiction who were being asked to accept the installed systems without any tools or guidance for accepting them. This standard was supposed to fill the void for the industry and give it an enforceable standard for use by the hydronic heating systems designers, installers and regulatory agencies. The joint task group on hydronic heating reviewed the 2007 edition of the CSA-B214, “Installation Code for Hydronic Heating Systems” and was satisfied that CSA had adequately addressed the concerns raised by the building code committees and that it fills the void created by the lack of an enforceable standard.

A CREDIBLE TOOL A proposal to reference this standard in Part 9 of the NBC was accepted by the relevant committee. With a reference to this standard being provided in Part 9 of the NBC, the regulatory agencies have access to a credible and an enforceable tool for hydronic heating systems, to support their enforcement activities and reduce ambiguity in the application of the building codes. Also, hydronic heating systems installers and designers are able to follow the rules of the game without having to deal with any misunderstandings or problems when dealing with the regulating authorities for such installations. However, when it came to referencing this standard in Part 6 of the NBC, which is under the Standing Committee on Building and Plumbing Services (SCBPS), they chose a different method. It is important to remember that Part 6 of the NBC is not very prescriptive and is generally used by professional designers and engineers who have more information and expertise at their disposal. Therefore, when it was recommended that CSA-B214, “Installation Code for Hydronic Heating Systems” be included in Sentence 6.2.1.4.(1) “Installation Standards” concerns were expressed by the public when this standard was subjected to public review. If this proposal was to get approved, the standard would no longer need to be referenced in Sentence 6.2.1.1.(1) which is generally a list of “good engineering practice” documents. The committee even considered adding a qualifier if it were to reference this standard in Sentence 6.2.1.4.(1) by adding hpacmag.com


Hydronics the words “for non-engineered systems.” Being an administrative requirement this was not allowed in the enforceable wording by established protocol of model codes. The change to include it as a reference in the list of installation standards was not accepted. The committee felt that the standard had deficiencies when considered for larger commercial or institutional building systems and was inferior compared to the guidance provided by ASHRAE documents. Therefore, it was more appropriate for referencing in Part 9, which tends to be prescriptive and the users have limited design resources. Generally the applications are limited to smaller residential and commercial buildings.

HEALTH AND SAFETY

cally-based practices on service water/space heating waterbased combination systems. The main concern of the NBC is the health and safety of the occupants and it applies to all systems. Thus, with regards to referencing the standard in Part 6 of the NBC, the Standing Committee on Building and Plumbing Services (SCBPS) committee responsible for Part 6 decided to include it as a referenced document in the requirement dealing with “good engineering practice.” The committee did not feel that the standard was technically adequate to have a separate reference in Part 6 of the NBC. In summary, the standard is referenced in Part 9 and in Part 6 it is in a reference with other standards under the “good engineering practice” label.

The committee also heard that the CSA B214 for the greater part deals with design and installation practices for the equipment and only a minimal part deals with health and safety. Specifically, the standard’s focus is on the issue of cross-contamination of potable water from the heating circuit water and does not contribute to establish scientifi-

HigH-Quality NortH americaN made For 79 years, Woodford Manufacturing Co. has been supplying the plumbing industry with the highest-quality North American made products. Our wide range of well-built wall faucets and hydrants are not the only reason to do business with Woodford. All Woodford products can be repaired in the field regardless of age. Individual parts or repair kits are readily available as we understand how important it is to keep projects on schedule or have repairs made quickly. Woodford repair kits also make it easy to execute in-line repairs and reduce the chance for unnecessary damage to surrounding surfaces and structures. Take a look at our family of wall, roof and yard hydrants, as well as our many faucet products that are all proudly made to the highest standards. Freezeless roof Hydrant model rHy1 or rHy2: The Woodford RHY1 provides water availability for window washing, cleaning condenser coils, cooling towers and other types of roof equipment. The valve body of the hydrant is drilled and tapped with an 1/8-inch drain hole, which must be piped to a drain location. Product features include: • Mounting system to make proper and secure installation to any roof. • Available with (RHY1) or without (RHY2) backflow protection on nozzle. • All repairs can be made from the top of the unit without removing hydrant. Parts are readily available. Freezeless Hot and cold Wall Faucet model 22/V22/22cc: The Woodford Model 22, with an improved design, has been upgraded with aluminum powder-coated oval handles standard and with the patented pressurerelief valve operating rods. The 22 series provides year-round hot and cold water service regardless of outside temperature. Separate hot and cold inlet tubes and operating handles allow for manually operated water temperature control.

Available in three models: • Model 22 Horizontal Mount – Rough Brass. • Model 22V Vertical Mount – Rough Brass (for end wall installation). • Model 22CC Close Coupled – Rough Brass (for use in nonfreeze areas; fits within 2-inch x 4-inch wall). Suggested uses include residential structures where hot and cold water service is required yearround; ideal for filling kids wading pools, washing dogs or cars with warm or hot water. Features: • Faucet drains automatically when hose is removed. • Permanent stainless-steel seat eliminates possible pitting of seat or wire draw and allows the faucet to be repaired regardless of age. • EPDM packing prevents leaking. • Loose Tee Key (optional). Optional: An RKPT Repair Kit is available at additional cost to convert the hot side handle to a "Push to Turn." This will reduce the potential to unintentionally turn on the hot water. New product feature: • An internal resetting pressure-relief valve prevents the faucet casing tubes from bursting in freezing conditions, even if a hose is unintentionally left on.

DON’T LET

WINTER WEATHER BURST YOUR BUBBLE

Freezeless AND Anti-Rupture? What’s the difference? A freezeless faucet has the shut off mechanism well within the heated portion of the home – but what if a garden hose or other device is inadvertently left connected to a faucet during freezing temperatures? Water in the tube fails to drain, this water then begins to freeze and pressure in the tube is increased as ice forms and tries to compress the water trapped in the tube. The tube ruptures and the next time the faucet is used the wall will fill with water. Woodford Model 19 Freezeless Faucets have a patented pressure relief valve which allows for expansion during freezing temperatures, saving the faucet and preventing a costly repair or call back. With Woodford’s Model 19, you’re protected – even from other people’s mistakes!

come as a surprise to anyone. Contractors and wholesalers that deal with the issue every day are looking for concrete steps to draw young people into the industry and appeared disappointed to hear about an academic research project to “determine the scope of the problem.” Everyone is already aware that many of the skilled tradesmen in this industry are getting older and will soon be retiring, joining many of their fellow workers that have already left. Too many owners are working the tools because they can’t find skilled workers. Wholesalers are having difficulty recruiting reliable employees with the required mechanical aptitude. Numerous older workers entered the industry through the high school shop programs that long served as a key recruiting arena for contractors and wholesalers, not to mention manufacturers. With that factor largely eliminated by academics intent on ensuring that everybody gets a university education, the industry disappeared from the radar screen of young people over the past 30 or so years. A new way is needed to draw

Canada student chapters and the Canadian Institute of Plumbing & Heating Co-op program, to name a few, are excellent steps in the right direction. Some provincial governments are running television advertising and other marketing to draw attention to their apprenticeship and trades programs – a welcome step that was long overdue. Several associations offer scholarships to help students cover the cost of attending school in an industry-related field. This is also helpful. But what really needs to occur is a change in mindset. Marketing the industry to youth should not be a response to a particular crisis nor should it depend on the “scope of the problem” and how the situation looks in the future. Marketing this industry to youth needs to be an ongoing and permanent effort. It needs to become a key mandate for every major association and every provincial government. While the need to study the issue and project labour requirements is not totally irrelevant, it is only a small part of a much bigger issue. The mechanical

program could go a long way in providing an ongoing pool of candidates to work in this industry. Do we need another study? Groan …

Back To The Future

T

he first documented CO2 compressor was built in 1880. The 1920s and early 1930s were the heyday for CO2. In particular, it was the preferred refrigerant for the shipping industry due to its non-toxic and non-flammable properties. By 1930, 80 per cent of all ships were using CO2 refrigeration systems. The 1927 ASHRAE Date Book sported an advertisement by the Carrier Engineering Corporation with the headline “We have no favorite son,” referring to the myriad refrigerants available to fit any application need. Among these were CO2, NH3 (Ammonia), and a newcomer designated F-12. It was F-12 (developed by DuPont and more commonly referred to by its trade name Freon, and designated as R-12), along with other CFC based refrigerants that brought about the demise of CO2. CO2, along with NH3, propane and butane belong to the family of “natural” refrigerants, termed for the obvious reason that they are not man-made. Each has their advantages and disadvantages. NH3 remains the dominant refrigerant for industrial refrigeration applications, but it is highly toxic. This is a severe limitation. You won’t see NH3 utilized in supermarkets, restaurants, or any other application that serves the general public. Hydrocarbons such as propane and butane are flammable. As stated above CO2 is neither toxic nor flammable and these are obvious benefits. So, what brought about the demise of CO2 in the 1930s? Several factors were at play: » Much higher operating pressure for a given temperature. » Narrow range of operating temperatures. » Triple point occurs at a much higher pressure than other common refrigerants. » Critical point occurs at a much lower temperature than other common refrigerants. » The advent of DuPont’s R-12, eliminating the above application and design difficulties in utilizing CO2. REMEMBER OZONE DEPLETION? Reminiscing to the chorus of Simon & Garfunkel’s song Mrs. Robinson, with the lyrics asking “where have you gone Joe DiMaggio,” I would ask the question “where have you gone F-12?” After all, it did upstage CO2 many years ago. The 96

HPAC | MARCH 2010

answer is of course quite obvious. Fast forward to the future where mankind’s impact on the global environment is an additional factor in determining system design and we can easily understand why R-12 and other CFCs lost their popularity (see sidebar, page 97). In June of 1989, then President Bush proposed sweeping changes to the Clean Air Act; amongst them Title VI-Stratospheric Ozone Protection. Passage of this bill essentially marked the end of chlorofluorocarbon (CFC) refrigerants, prohibiting their production after the year 1999. Title VI also put the production phase-out of hydrochlorofluorocarbons (HCFCs) into motion. Although the implementation of Title VI affected an array of CFC refrigerants, it was the inclusion of R-12 and R-502 (an azeotrope containing the CFC R-115) that caused the greatest concern for owners of refrigeration equipment. A complete phase-out would not occur overnight and incentives were applied to these refrigerants to encourage phase-out. Commercial refrigeration equipment owners were compelled to move away from the tried and true refrigerants into unknown territory with many new choices. A completely different set of challenges faced the refrigeration industry, including: » The design and manufacture of new environmentallyfriendly refrigerants. » Refrigerant/lubricant compatibility. » Refrigerant leaks and leak detection issues. » System component redesign. » Re-educating the technical workforce. In addition, three cottage industries were born: refrigerant reclaim equipment manufacturing: refrigerant conversion; and refrigerant reclaim/recycle services. The first wave of refrigerant conversions for refrigeration applications centred on the elimination of CFCs and could be categorized as follows: (1) R-12 systems converted to R-134A, Hot Shot (R-414B), MP39 (R-401A), or one of several other R-12 replacements, (2) R-502 systems converted to HFCs R-404A/R-507/R-402A, and (3) R-502 systems converted to R-22. continued on page 98 HPACMAG.COM

The resurgence of CO2 as a viable refrigerant alternative lends credence to the proverb: The more things change, the more they stay the same. BY DAVE DEMMA


A WORLDWIDE PERSPECTIVE…

WHY CO2 HAS ONCE AGAIN BECOME A VIABLE REFRIGERANT EU members Austria and Denmark were allowed to maintain more stringent measures until 2012, banning the import, sale and use of new products containing F-gases as well as banning the import, sale and use of F-gases, new and recovered. Denmark and Sweden have tax and refund schemes where they are taxed on their HFC but receive a refund for the amount of HFC they return for disposal. Denmark has banned HFCs from new equipment. Austria has banned HFCs from domestic use. In addition, Switzerland also has bans on HFCs in some products and Norway has a high GWP-weighted tax on the sale of HFCs. Using CO2 and other natural refrigerants in commercial refrigeration become even more cost-efficient in Germany, following an announcement of the Environment Ministry in 2008. Based on a “StatusCheck” to evaluate the energy efficiency potential of existing systems, the government thus co-funds new energy-efficient installations using climate-friendly refrigerants, state-of-the-art components, and control mechanism monitoring a system’s life cycle climate performance. R744.com In the UK, the “Hydrofluorocarbons Limitation Bill 2008 - 09” (Bill 127) seeks to make provisions for limiting the use of HFCs in certain premises. More specifically, it will end the use of HFCs in the refrigeration units of large supermarkets, as opposed to small retailers (i.e. corner convenience stores) that would only be required to introduce equipment that do not contribute to global warming when their old units need to be replaced. Under plans to reduce greenhouse gas emissions unveiled recently, the Australian government will put in place incentives to drive the transition to natural refrigerants such as CO2. The CPRS will apply pressure to phase out the use of high- GWP HFCs by making them subject to a strong price mechanism. Scheme obligations will be applied to large importers. Existing import levies will be raised to achieve an equivalent HPACMAG.COM

carbon price on all synthetic greenhouse gases sold in Australia. The California Air Resources Board (CARB) published its final “Climate Change Proposed Scoping Plan” in 2009, a comprehensive document proposing a set of actions to reduce overall greenhouse gas emissions in the state. Compared to previous draft versions, the final version has added a recommendation to establish a fee on sales of gases driving global warming, increasing pressure towards a future phase out of high global warming gases. Once adopted, the plan could accelerate the use of alternatives to these chemicals, as seen already in other world regions. In line with the ‘polluter pays’ principle, a tenet of environmental law, which states that the party responsible for producing pollution should be responsible to pay for the damage done to the environment, Greenpeace believes that “governments should legally compel the chemical industry to contribute funds towards the cost of eliminating CFCs, HCFCs and HFCs.” “The fluorine-containing compounds also persist longer than carbon dioxide and other major global warming agents,” said Timothy Lee, chief of the space science and astrobiology division at NASA Ames Research Center and leader of a study of more than a dozen chemicals listed as warming agents by the Intergovernmental Panel on Climate Change. He pointed to the urgency of moving away from such substances to fluorine-free substances such as R744. “The concern is that, even if emitted into the atmosphere in lower quantities, the chemicals might have a powerful cumulative effect over time. Some of these chemicals don’t break down for thousands of years.” The London 2012 Committee of the Olympic Games and Paralympic Games (LOCOG) has published the first online edition of its Sustainable Sourcing Code, reiterating its commitment to making the 2012 Games sustainable. According to the Code, “chilling or cooling equipment containing substances with a global warming potential of 150 or more in composition should be avoided.” Source R744.com MARCH 2010 | HPAC

Concurrent with the increasing frequency of existing refrigeration equipment undergoing refrigerant conversions, equipment manufacturers began phasing out the production of new equipment utilizing CFCs. In addition to the availability of newly designed equipment using HFCs R-134A, R-404A and R-507, there was a remarkable resurgence of refrigeration equipment designed and manufactured with R-22. During this period of time contractor confidence in R-22 was relatively high in comparison to HFCs due to its familiarity and proven ability. In addition to being a staple in the air-conditioning industry, R-22 had been used for refrigeration applications in the 1960s, prior to the development of R-502. While R-22 would undergo its own phase-out in years to come, during the phase-out of CFCs it proved to be a viable alternate refrigerant, and became the favourite interim refrigerant for new refrigeration equipment and R-502 conversions. There were a few potential shortcomings with R-22 as a refrigerant for refrigeration applications. When used for low temperature applications, single stage compressors operated at higher compression ratios and the probability for excessive discharge temperatures was always present. However, with proper design, those shortcomings could be minimized. The two main benefits in converting from a CFC to R-22 were: R-22’s relative low cost as a refrigerant, and R-22 did not require the use of POE oil. The only real drawback with R-22 as an interim refrigerant is that it was an interim refrigerant. We have arrived at the point where it is time to pay the piper. Recent surveys have suggested that over 80 per cent of commercial refrigeration equipment owners who convert to more environmentally-friendly refrigerants do so to comply with regulations. One might logically deduct that part of the interest in compliance is based on a desire to avoid the hefty penalties assessed to owners of leak-ridden equipment. A paltry 18 per cent of equipment owners are converting for reasons of genuine environmental concern. Whatever the real motives are, converting from the interim R-22 to an HFC has become the second wave of conversions to sweep the industry. The prudent refrigeration equipment owner is now developing and implementing plans to convert their existing systems from R-22 to a viable HFC option. We are already seeing tremendous activity in the bakery and supermarket industry. Once again, this wave of conversions is coupled by the halting of production of new equipment utilizing R-22. Every refrigeration contractor will be expected by his customer base to be an expert in the refrigerant conversion process. If you have not had the opportunity to complete 98

an R-22 to HFC conversion yet, you most certainly will. And if that is not enough, we now find that ozone depletion is not quite the concern it was once thought to be. Global warming has moved into the top position of current environmental concern (the Climategate saga notwithstanding). And unfortunately, the refrigerants that were designed to save us from ozone depletion have high global warming potential (GWP). R-404A and R-507, the environmentally friendly refrigerants designed to replace R-502, are not as environmentally friendly as was originally presumed (see Figure 1).

In short, due to the united concern over global warming, and HFC’s high GWP, their long-term viability for use in the refrigeration industry does not look promising. In fact, a death warrant has been issued and in short time the collective coroners of the world will add their signature to it. So, what better “new” alternative refrigerant than one that is not flammable, is non-toxic and has an ODP and GWP of 0? While there are some challenges to overcome in using CO2 for refrigeration applications, the criteria of environmentally friendly has once again brought CO2 to the forefront of the refrigeration industry. Whether or not it is the best choice is a moot point. There is significant global momentum to propel CO2 to its former position as a dominant refrigerant of choice.

he increasing acceptance and growth of on-demand tankless water heaters sales in North America have been driven by three distinct groups of proven benefits they bring to the marketplace. The first group includes answers to present and future rising energy costs, CO2 emissions and their role in climate change. Secondly, when properly sized and installed, the tankless water heater provides realistic energy savings, the convenience of continuous water flows without storing hot water, space savings and long product life. Thirdly, various government and utility incentives encourage increased water heater efficiencies based on minimum standards that tankless water heaters can meet. While still relatively new to many of us in North America, tankless water heaters have been around for a long time in other areas of the world. Typically these are countries that have always had to live with high costs of energy that we are starting to see in North America. The first recorded use of early versions of gas-fired ondemand water heaters appeared in the 1880s in Europe. Prior to the invention and use of gas, hot water was only available in the kitchen in most homes. Only cold water was piped to other areas in the building. With the evolution of uses of gas, early gas-fired copper coil heaters were developed and most installed at these same remote cold water locations, hence the term “point of use” or “on-demand” water heaters. By the 1930s units were being manufactured in Asia and the U.K. under licence. By the 1970s they all looked and operated similarly with simple mechanical controls and standing pilots. The 1980s saw the introduction and evolution of the electronic non-piloted models

“While a rapidly increasing number of North American consumers are accepting the fact that their lifestyles around hot water use must change, it is important that you as a contractor establish the sizing ground rules of the sale with the customer.” leading to today’s selection of tankless products ranging from small cottage models, up to large 200,000 plus Btu all-purpose units. Most of the larger units can be installed in multiples and, when hooked together with a simple plug-in cord, automatically cascade in sequence to handle both small and extra large flows. Solar back-up controls are usually standard. Proper venting is important regardless of local codes that may relax venting requirements. For the best results it is recommended that the manufacturer’s instructions be followed. These larger units are ideal for the larger family homes and in multiples, open the door to many commercial and industrial applications. SIZING AND THE SALE In other parts of the world, where energy costs have always been high, most peoples’ life styles have grown up around the use of tankless water heaters with times allocated for shower, bath and laundry use. While a rapidly increasing number of North American consumers are accepting the fact that their life styles around hot water use must change, it is important that you as a contractor establish the sizing ground rules of the sale with the customer. » Sizing should take into consideration not only the size of existing occupancy but possible occupancy for future resale value of the home. » If an in-law or rental suite is involved, maximum tenancy should be included as part of the family or a separate smaller unit should be installed for the suite. » Most residential customers opting for tankless are also conservationists and are probably aware that low flow appliances not only save energy but also conserve water which, it would appear, is also the goal of many municipalities already. This is a good time to make the customer aware of the various low flow appliances and adaptors that are available. It all ties in with sizing. » Cost of fixed flow showerheads are minimal compared to main cost of equipment and sizing should be based on max 2.5 USGPM. Get commitment on number of showers they want to run at same time. Be aware of multiple 102

head shower stalls and flood type showerheads. Preach conservation. » Large soaker type tub and spa use is not normally an every day event and can generally be scheduled to fit into daily hot water use. » Present day dishwashers and washing machines fill rates are relatively low. Hot water use can also be accommodated by planning and can become routine at separate times to other uses. » When using the manufacturer’s flow sizing and temperature rise charts, be aware of winter time cold water inlet temperatures for your area. While most ground water sources rarely go below 40F(4.4C), surface water sources from lakes and streams in some areas can approach 33F (0.5C) » Best performance is with 30 to 40 PSI inlet water pressure. Well pump controls should be set for 40 to 60 range. SERVICE All gas fired equipment, regardless if it is a furnace, boiler or water heater should be checked and serviced on a regular basis as recommended by the manufacturer. Tankless are no different and will give long trouble free life if looked after. Hopefully, the gas utilities, as they increasingly focus attention on the benefits of higher efficiencies towards saving energy and reducing CO2 emissions, can also work more closely with the servicing contractors to sell the consumer on the need and material benefits of having a preventative service contract. When sized and installed properly tankless water heaters have performed well in the field. They also have the advantage that every part is replaceable in the field and every part is recyclable. We are still providing parts to units sold in the 1980s. Normally, if it develops a leak it will drip first giving adequate warning for service, rarely flooding or prompting emergency call for service under normal conditions. HVAC contractors should look at tankless waters as a possible new profit centre. Pat Martin is with Astravan Distributors Ltd.

Interviewing and Selection It’s Worth Doing Right

Every company has many resources that comprise its business. Among them is the capital to start and grow the business, the technology to provide information, communication and service both internally and externally, tools and equipment and of course people. BY CHRISTA HALE

THE RECRUITING PROCESS Investing time, effort and good recruiting practices are therefore a “must” to having the best people in place to run your business. Recruiting is a costly and time-consuming activity. Before commencing with a recruiting initiative, make certain that you have explored all possible options in terms of fulfilling your resource needs. You should ask the following questions: »» Is our employee requirement seasonal, temporary, parttime/full-time permanent? »» Do we have any internal employees who are capable of taking on additional challenges or who could be transferred/promoted to this position? Once you decide to actively recruit for the position, the quality of the recruiting process from beginning to end will ultimately determine the success of the new hire.

QUESTIONS TO KEEP TO YOURSELF It is illegal to ask employees or potential employees questions relating to their age, place of origin, personal/domestic situation, marital status, criminal record, religious and sexual orientation.

106

HPAC | March 2010

Short cuts to this process will inevitably lead to surprises down the road, which in most instances could have been avoided. The recruiting recipe requires the following key ingredients: »» A well-defined job description containing major duties to be performed, the experience, skills and knowledge required to perform the job and any unusual/unique working conditions of the position. »» Identify the recruiting vehicles you wish to use: Word of mouth: referrals from existing employees; academic institutions; professional organizations; newspapers, web sites and professional journals/magazines; your bank of recent candidates, external human resources consultants, and so on. Establish a formal interviewing process with a set of questions that will be asked of all candidates. Remember that the objective of the interviewing process is to collect information in an organized manner, about the candidate’s ability to successfully perform the key components of a given job. These questions are your key tools for evaluating candidates. Major areas to include in your interview questions are: »» Past work experience and accomplishments. »» Why is the employee looking for a new job? »» Salary history and future pay expectations. continued on page 108 hpacmag.com

enerally, owners and senior managers in companies dedicate a lot of time to researching and buying the best equipment, tools, technology, buildings, etc., to support their business operations. What they sometimes fail to consider is that people who effectively control, plan, deliver and manage all other company resources will contribute more to the company’s business and financial success than any other resource. Therefore, people are the only resource that will ultimately determine the success or failure of your business.

THE STEPS TO TAKE

1

First and foremost you need to get the company and its records in order. This could take anywhere from two to six months. Your tax planning should already be in place and you should check with your accountant to confirm that the sale of your business has been considered as part of your tax planning. During this phase of the process your advisor will collect information on the operations of the business, including: the ownership; employees; statistics and trends in the industry; competitors; your competitive advantage; and your historical and projected financial information. With this information your advisor will prepare a Confidential Information Memorandum (CIM) describing 110

HPAC | MARCH 2010

the main aspects of your business. This exercise will also help prepare you for the due diligence requirements.

2

Academically speaking, the value of any company at a point in time is the net present value of its future earnings potential. A more practical way of expressing this sentiment is achieved by putting a multiple on your EBITDA. EBITDA is simply calculated by adding your interest expense, depreciation and amortization to your pre-tax earnings found on your income statement. Determining what multiple to choose is a function of estimating how sustainable the EBITDA will be in the future and what growth prospects there are for the EBITDA. The more sustainable and the more growth expected results in a higher multiple. For purposes of determining a valuation of the business, the EBITDA will be reduced by any capital or other annual expenditures that are required to sustain the business. If you have long-term debt on your balance sheet the proceeds will be reduced by the amount of debt the purchaser is acquiring. In summary, if you generated $2 million in net EBITDA last year and you have good prospects for continued profitability, a conservative estimate would be an $8 to $10 million purchase price. There are always other factors that may help or hinder the multiple. Your geographic location may be a plus or minus depending on the buyer, specific HPACMAG.COM

he number of Canadian HVAC/R service companies, sold recently, affirms the demand in the marketplace for the acquisition of HVAC/R contracting companies. These fall into two categories: those that specialize in commercial and industrial customers, and those focussed on the residential market. There is also demand for distribution and manufacturing companies but these categories require much larger earnings to get buyersâ&#x20AC;&#x2122; interest. Commercial and industrial companies will get higher multiples of EBITDA â&#x20AC;&#x201C; Earnings Before Interest, Taxes, Depreciation and Amortization (see below) than residential contracting companies because of their recurring revenue. In some cases commercial companies will have customers for decades. This provides a revenue stream, which has a good degree of certainty and allows the buyer to pay for that future cash stream. As such, residential businesses will sell for 2.5 to five times EBITDA, while commercial company prices range from four to six times EBITDA.

Strategic buyers in your industry are the best prospects and, more often than not, that will be a larger, direct competitor. Financial buyers such as private equity firms are also becoming more active for the larger deals. Your advisor will prepare a list, with your assistance, to determine the best prospects. Before any information is sent to prospective buyers they will be required to sign a Confidentiality Agreement.

The Confidential Information Memoranda, which is often called The Book, is the thorough summary of your business referred to in Step 1. It is provided to prospective buyers.

Prospective buyers will want to have site visits and ask additional questions specifically relevant to them.

Those that are interested in bidding will deliver a Letter of Intent. These are non-binding letters, which outline the price and structure of the proposed transaction, as well as the broad terms and conditions the prospective buyers are proposing. It forms the basis for negotiations that will lead to the final deal. HPACMAG.COM

Buyer’s Due Diligence involves the buyer reviewing all legal, accounting, tax, banking, human resources, health and safety, information systems, real estate and other material contracts. They will also make investigations into products, customers, outstanding litigation, environmental issues and so forth. This is a time-consuming process and requires a great deal of preparation. The lawyers paper the legal documentation for the deal but negotiations continue throughout this stage of the process. Money changes hands and the keys are passed to the buyer at the final step – the Closing.

Selling a business is a complicated, time-consuming and often stressful event. Given the magnitude of these transactions, retaining the advice and assistance of a professional with experience in the financial transaction markets may be prudent. That person will not only manage the process while you continue to run your business, but will also act as a buffer in the negotiation process. Mark Groulx is president of A.I.M. Group Canada.

Anatomy Of A Solar Drainback System – Part I BY JOHN SIEGENTHALER

A

fter 30 years of designing and installing hydronic systems I have developed a philosophical statement about antifreeze solutions: “The only good thing about antifreeze is that it doesn’t freeze.” Although these words certainly do not rank up there with other notable quotes, they none-the-less suggest that use of antifreeze in hydronic systems has some “baggage” associated with it. Here is a quick summary: » Glycol-based antifreezes lower the specific heat of the solution. For example, a 50 per cent (by volume) solution of propylene glycol has a specific heat of about 0.86 Btu/lb/ºF. That is 14 per cent lower than the specific heat of plain water (1.00 Btu/lb/ºF). Mixing antifreeze with water “dilutes” the ability of the fluid to absorb and transport heat. » Glycol-based antifreeze solutions have significantly higher viscosity than water. This increases the pumping power necessary to move them through a piping system relative to water. The head loss of a piping circuit operating with 50 per cent propylene glycol increases about 39 per cent compared to the same circuit operating with water. When the flow rate is increased to compensate for the lower specific heat, the pumping power requirement for 50 per cent propylene glycol is about 66 per cent higher than for water. » Antifreeze has a propensity to weep through threaded joints, even joints that have passed an air pressure test. The evidence of such weeping is discolouration on the joint (usually a bluish or bluish/brown scale on the joint). Ask anybody who has dealt with antifreeze about this and they immediately know what you are referring to. » Adding antifreeze increases the cost of the installation. » Last, but certainly not least, the high temperatures reached in a stagnating solar collector (350+ ºF) can quickly convert glycol-based antifreeze solutions into an acidic mix. This is the single biggest issue surrounding the life expectancy of glycol-based solar thermal systems. It requires the use of a heat dump subsystem to divert excess summer heat into some dissipating

114

HPAC | March 2010

media such as pool water, the outside air, or even a coil of tubing buried in the earth. Such provisions certainly add further cost and complexity to the system. So, if antifreeze has so many issues, why is it used in the majority of solar thermal DHW systems? Opinions vary on this, but I think it is because this approach allows installation of the piping between the collectors and storage tank to take any available route (up, down, around, under, over, and so on). Since the fluid remains in the circuit there is no need for any specific pitch.

ANTI-ANTIFREEZE All solar thermal systems installed in North America must be protected against freezing. Rather than using antifreeze and leaving the fluid in the collectors, it is possible to drain all water from the collectors and any piping installed in nonheated space whenever freezing conditions are imminent. There is more than one way to do this. One approach is called a “draindown” system. A schematic of the concept is shown in Figure 1. The concept behind draindown systems is straightforward: The collectors, piping, and tank all contain pressurized domestic water. When a temperature sensor detects a near-freezing condition near the bottom of the collector, two electrically-operated solenoid valves close to isolate the storage tank from the collectors and exposed piping. A third solenoid valve opens to allow the water in the collectors and exposed piping to drain out. A vacuum breaker at the top of the collector array allows air in to expedite drainage. Most of the time all this works as it is supposed to. Unfortunately, most of the time is not good enough. If one of the valves sticks, or a freeze detecting sensor drifts out of calibration, the result can be a costly hard freeze. There is also concern about scaling or corrosion caused by fresh potable water in the solar collectors. Replacing a scaled collector array is a lot more problematic and expensive than replacing a scaled water heater. The solar thermal industry made a diligent effort to make draindown systems work back in the '80s. It finally concluded there are just to many things that can go wrong. hpacmag.com


FIGURE 2

DRAINBACK SYSTEMS Gravity is a very reliable phenomenon. Why not put it to work ensuring that water exits a solar collector array whenever the system is not operating? That is exactly what a drainback system does. When the collector circulator shuts off, the water in the collector array and exposed piping immediately drains back to a reservoir within heated space. No valves, no freeze sensors and no vacuum breakers are needed. The basic system concept is shown in Figure 2. When the differential temperature controller determines it is time to collect heat, it turns on the collector circulator(s). In some drainback systems this is a single high head circulator. Other drainback systems use two circulators mounted in series. In either case, the circulator(s) must be capable of lifting water from the static water level (shown by the dashed green line), all the way to the top of the collector array. What happens next always impresses me. With sufficient flow velocity, the water passing over the top of the piping circuit begins to entrain air and drag it back down toward the storage tank. Eventually, all the air in the return pipe is either pushed or dragged back to the drainback space at the top of the storage tank. The filled return riser acts as a siphon, and essentially cancels out the lift head. The FIGURE 1

system then operates very similar to a closed loop/fluid filled hydronic circuit. In systems with two circulators it is possible to turn off the upper circulators once the siphon is established. This cuts the electrical wattage to maintain flow through the collector array in half. One of the biggest advantages of drainback systems is that no antifreeze is required. This not only eliminates the cost of the fluid, but also that associated with a heat dump provision to protect the fluid during collector stagnation. When stagnation conditions occur there is no water in the collectors. I call this dry stagnation. All collectors meeting the current OG-100 rating from the Solar Rating and Certification Corporation (SRCC) must pass a stagnation test to prove they can survive such conditions. Some drainback systems, like the one in Figure 2, also eliminate the need of heat exchangers between the collector and the water in the storage tank. The same water that passes through the space heating circuits also passes through the collector. This allows for minimum supply water temperature to the collectors and thus maximum efficiency. This, along with dry stagnation, make drainback systems ideal for combisystems that supply domestic hot water and space heating. There are several details required to construct a good drainback system. We will get into the specifics in the next Solar Panel column.

Taking it one step further, being able to locate and use a drench shower or eyewash unit in an emergency can be nearly impossible. By Heather Koehn

O

ne of the biggest barriers to accessibility may be that there is not a global standard for installing emergency fixtures to ensure that they are barrier free. The United States has the Americans with Disabilities Act (ADA), but even these guidelines do not specifically mention emergency fixtures. However, the ADA is the guideline used for emergency fixtures, because general requirements such as reach heights, knee clearance, and operation of controls for similar plumbed products can be extrapolated and used in the design of emergency equipment. The term â&#x20AC;&#x2DC;barrier freeâ&#x20AC;&#x2122; refers to products not specifically covered by the ADA, but that are designed to follow the guidelines set by the ADA. While there is not a Canadian equivalent to the ADA, the intent of these guidelines is as much of a Canadian ideal as an American one. The act was established to give equal rights and access to individuals with physical disabilities, and help prevent discrimination against their use and enjoyment of public facilities. Products designed with this intent also allow workers with physical limitations to be comfortable, safe and productive in the workplace. Thinking about it this way, it just makes sense to follow a set of guidelines that insures all people will be accommodated in both public facilities and the workplace. On the product front, a number of barrier-free emergency fixtures are available that meet the intent of the ADA. Many are designed to be universal and will accommodate any user. Growing demand for drench showers and eyewashes in different markets is creating a need for new emergency fixture solutions and models for a range of applications, not just industrial facilities.

Recessed-mounted fixtures are fully accessible and fit seamlessly into the surroundings.

RECESSED EMERGENCY FIXTURES One of the best examples of a product category designed to fit the needs of schools, hospitals, laboratories and others concerned with aesthetics and space is recessed-mounted drench showers and eyewash units. These barrier free fixtures have a slim profile against the wall and are made of stainless steel to seamlessly fit within their surroundings. Rather than having a plumbing pipe sticking out from

the wall, and a fixture taking up floor space, all of the mechanicals are housed inside the wall and the front panel is flush mounted. The completely barrier-free design makes recessedmounted fixtures fully accessible to those with physical disabilities. Depending on the type of hazard, eyewash units, drench showers or combination shower/eyewash units are available. Many facilities find the combination units to be versatile because they save space when both types of emergency fixtures are needed. With recessed units, the eyewash station is concealed behind a swing-down cabinet door. The valve is activated as soon as the door is opened. During use, water is collected inside the door and funneled to a drain in the back of the unit. When the door is closed, any remaining water drains directly back into the wall. On models with a drench shower, either a flush-mounted or a standard showerhead can be specified. The shower

hpacmag.com

is activated by pressing down the shower handle on the front of the unit. In a barrier free product, no twisting, tight grasping or turning should be required to activate the shower. These emergency valves are designed to remain open until the lever is lifted and the user has completed a full 15-minute flush. When specifying a recessed-mounted emergency fixture, or any other type for that matter, look for fixtures that comply with the American National Standards Institute (ANSI) Z358.1-2004 standard for emergency drench showers and eyewashes. This means the fixtures have been thirdparty certified to the ANSI standard and ensures that the minimum water flow, spray pattern and other requirements have been met. Another consideration is serviceability. Models with wide access panels in the front can be easily maintained. continued on page 120

EYEWASHES WITHIN REACH Another option is a barrier-free wall-mounted eyewash fixture. Stainless steel models and others with a brightly coloured safety coating are available. These more traditional wallmounted units have a few special modifications, which make them easier to access and use. According to the ADA, faucets must be operable with one hand and should be activated using a maximum of five pounds of force. So, for an eyewash, rather than requiring pushing or pulling a knob to activate the valve, the unit may have a large push handle with a visible sign showing users how to turn it on. As with other types of fixtures, clearance height, reach height and wall clearance are key considerations for meeting the intent of the ADA guidelines. The maximum high forward

When selecting an emergency fixture, look for features that make the units easier for anyone to use. Activation should be simple and easy. Drench showers with a triangular-shaped pull rod, for example, allow a person to stick their arm through the hole to activate. This may be critical if a user’s hand is burned in a chemical accident and they become instantly disabled and unable to grasp a cord with their fingers.

CLEARING THE WAY Ideally, emergency equipment will be used infrequently. While it is common sense to keep the pathway clear, often the area in front of an emergency fixture becomes a convenient storage area for boxes and equipment. To minimize injuries, users should not be required to weave a path

“Growing demand for drench showers and eyewashes in different markets is creating a need for new emergency fixture solutions and models for a range of applications, not just industrial facilities.” reach over an obstruction that is 20-inches long (51 cm) or less is a maximum of 58 inches (122 cm) above the floor. If the fixture is more than 20-inches deep, the maximum reach height is 44 inches (112 cm). When applied to an eyewash station, this means the activation handle can be no higher than these maximums, which depend on how far the fixture protrudes from the wall. Knee clearance under the eyewash should be at least 27 inches (69 cm). The standard clearance would also apply to eyewashes mounted to countertops in laboratories. Clear floor space is also an issue. If someone is expected to turn a wheelchair in front of a fixture, there should be at least 32 inches (81 cm) of clear space.

EASY-TO USE DRENCH SHOWERS Drench showers, like their eyewash counterparts, are offered in barrier-free models. Specifications for barrierfree units include proper placement of showerheads and extended pull rods. Wheelchair bound users should be able to reach a pull rod that is a maximum of 48 inches high. Shower heads must be a maximum of 96 inches from the floor to provide adequate flushing. 120

through clutter, and physically disabled workers cannot go up or down stairs to reach a fixture. Be sure fixtures are easy to find. The area should be well lighted and have a visible sign for quick identification. Selecting fixtures with a safety-yellow coating makes them easy to locate in an emergency, particularly for users with impaired sight. Yellow is the most visible of all colors and is the first color the human eye sees. In an emergency, if others are nearby, they will come to assist the injured victim. Yet, a disabled individual must have quick access to an emergency fixture so they can immediately begin flushing their eyes or skin to prevent more serious injuries. When designing an emergency plan, remove any barriers and choose products that are universal so that fixtures are accessible to all users.

135 Years of Plumbing innovation OneFlow Scale Control System. For years building owners, property managers, and facility engineers have fought the battle against scale and its destructive effects. Now there is a better solution that is environmentally friendly and virtually maintenance-free: OneFlow from Watts. OneFlow prevents scale by transforming dissolved hardness minerals into harmless, inactive, microscopic crystal particles which flow freely through the system without adhering to pipes, fixtures, valves or heating elements. OneFlow is not a water softener; it is a scale control technology designed to protect complete plumbing systems or individual components from the negative effects of water hardness. OneFlow uses “green” technology requiring no backwashing, no salt, and no electricity. OneFlow models are available in cartridge and tank style housings for commercial applications on both cold and hot water lines. Systems are available in many connection sizes to meet flow rates from 0.5 to 450 gpm or more. visit thescalesolution.com BLÜCHER: A new system of stainless drains.

Evolution…

And Capital Gains Tax Making any change takes energy and since evolution dictates that we not expend energy when we do not have to, we tend to keep doing what we do with no changes. This can be costly. BY Hank Bulmash

T

he prime way to save energy is to ignore long-term threats (which are mostly theoretical) and to focus fiercely on the short term (which is real). Anything we do to deal with the long-term is counter-evolutionary, energy-wasteful and not what we are designed for. That may explain why the capital gains exemption is so often ignored. The capital gains exemption is a gift that could be worth from $170,000 in

exemption is one of those times when it does not. The capital gains exemption allows an unlimited number of shareholders of a small business corporation to shelter capital gains up to $750,000 on the sale of the shares. If you shelter a full $750,000, you will save about $170,000 in capital gains taxes. But if you have a wife and three children, you can create a plan for all five of you to use the exemption. That would allow the

company. Doing so protects those assets from creditors and will actually help you safeguard the financial future of your family. You should not wait to do this. It does not cost much and it is better than any insurance policy. It should be considered even if you do not expect to use the capital gains exemption itself. Many entrepreneurs can’t bring themselves to take this simple planning step since it goes against biases that are

“The capital gains exemption is a gift that could be worth from $170,000 in saved taxes, to say $850,000.” saved taxes to say $850,000. But you likely won’t plan to use it. And if you do plan to use it, it is quite likely that you won’t take advantage of everything it has to offer. Why is that? Using the capital gains exemption requires a commitment to long-term thinking and most entrepreneurs who could use the exemption are successful because of their highly-evolved shortterm focus. They are good at saving energy for the essential immediate problems and they do not waste much energy on the long-term. That works well almost all the time, except when it does not. And use of the capital gains

family to shelter capital gains of $3.75 million, which translates into tax savings of $850,000. There are several tests that have to be passed in order to make use of the exemption. Professional guidance is required to make sure you pass them and you should discuss the issue with your accountant, lawyer or financial counsel. The most difficult test to pass requires that 90 per cent or more of the assets of the company whose shares are sold must be used in an active business. That is a blessing in disguise since it requires you to shift redundant assets, such as your savings, to another

buried deep in their psyche. The capital gains exemption and creditor protection plans are the most woefully under-used mechanisms in the financial planning toolbox. It is time to get beyond the hesitation and take advantage of this opportunity to save taxes and safeguard your assets.
