< UPFRONT THE NOOSE TIGHTENS ON THE HVAC/R LABOUR MARKET In May 2013, a report from the C.D. Howe Institute identified outdated provincial regulations as needlessly limiting the number of apprenticeship opportunities available to trades workers. Robbie Brydon and Benjamin Dachis, authors of “Access Denied: The Effect of Apprenticeship Restrictions in Skilled Trades,” 1 said that reforming those tight regulations was crucial to meeting demand for skilled workers. Brydon and Dachis recommended that instead of regulating the rate of apprentice entry, governments should focus on regulating quality of work and safety standards. More recently, the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), together with the HVACR Workforce Development Foundation in the U.S., released three labour market reports.2 The report findings reveal that despite an increase in programs available and a rise in enrollment, there is still a forecasted skills shortage across Canada. This is attributed to fewer professionals entering the industry than will be required to fill the positions being vacated by baby boomers. BuildForce Canada’s Labour Market Information (LMI) system forecasts that the greatest increase in skills shortages will be seen between 2017 and 2024.

HPAC | OCTOBER 2015

HRAI contends that with the exception of HVAC/R technicians and air conditioning and refrigeration mechanics, most other HVAC related occupations, such as gas fitters, plumbers and pipe fitters, have mobility between different industries within the construction sector. This means that several industries will be hiring from the same relatively small labour pool. This competition within the construction sector can negatively impact the HVAC/R industry in areas where skilled labour shortages are greatest. HRAI notes that provincial regulations and certification requirements can also become a negative factor as they often differ from one province to another, as well as between the U.S. and Canada. The issues surrounding labour shortages in the mechanical industry are clear. It is the solution that appears to be elusive. Check out the reports and let us know what you think!

Skills/Compétences Canada, a national not-for-profit organization, recently announced that Team Canada was presented with two silver and three bronze medals at the WorldSkills São Paulo 2015 competition. The team of 29 young skills champions also received 10 medallions for excellence at the event in August. “Team Canada’s performance was better than the last couple of years but obviously we want to keep improving,” said Shaun Thorson, CEO SkillsCanada. Thorson explained that it is a long process for competitors to get to this level of excellence. He says that participants are selected from the nationals competitions, and undergo a rigorous training program. After training alongside experts, competitors participate in the WorldSkills Canadian trial, which is a benchmark performance. If they succeed at this checkpoint, they are officially part of the team. In an interview with HPAC following the competition, Ken Howe explained that he takes great pride in his trade, plumbing, and enjoys that he can express his perfectionist nature through his work. He walked away from São Paulo with a medal of excellence in the plumbing and heating category and describes the event as life changing. “I gave it my all at the competition and I’m very satisfied with how it worked out,” he said. “This trade forces you to set goals and follow through with them, and just because I reached this level doesn’t mean my goal setting has stopped.” Howe owns his own heating and plumbing company and says he is already putting the skills he learned to use. Marc-Antoine Bettez won the bronze medal in the refrigeration and air conditioning category. “Even if you are told that it [WorldSkills competition] will be big, you only realize it once you are there. It’s really, I mean, BIG! I had to learn to manage my stress and stay focussed,” he said. Bettez explained that this is the most prestigious trades and technologies competition in the world, and this year 1189 young people from 59 countries and regions participated. Bettez told HPAC that he has realized that this competition is a great career springboard and that the intensive training he was involved in prior to the competition has increased his enthusiasm and reinforced working safely. Bettez has been an employee of Nordic Refrigeration since November 2014.

“The dedication, training and skills that these talented young individuals have demonstrated is truly remarkable and will help them forward as they pursue careers in Canada’s skilled trade and technology workforce,” said Thorson. WorldSkills is the largest international competition of its kind. This event takes place every two years and competitors are chosen from WorldSkills’ Member countries and regions. Competitors must be under 23 years of age to participate. The 22nd Skills Canada National Competition will be held June 5 to 8, 2016, in Moncton NB. www.skillscompetencescanada.com www.worldskills.org Editor’s Note: HPAC Magazine also spoke with Ken Howe from Monarch, AB and Marc-Antoine Bettez of Hérbertville, QC prior to the competition.

NEW YORK CITY ADOPTS ASHRAE’S LEGIONELLA STANDARD New York City council is now embracing legislation that adheres to part of ASHRAE’s newly published Legionella standard. This change in legislation follows 120 cases of infection due to Legionellosis and 12 confirmed deaths from the infection. At press time, New York had declared the outbreak over. The legislation addresses registration and inspection of cooling towers. It requires owners to create and file a plan to maintain equipment to comply with Section 7.2 of ANSI/ ASHRAE Standard 188-2915: Risk Management for Building Water Systems. “Although the circumstances surrounding its use are tragic, ASHRAE is grateful that the standard is available to set requirements to manage risk of this bacteria. We are hopeful other governments will follow the lead of the New York City council to help safeguard public health,” said David Underwood, ASHRAE president. This standard provides minimum Legionellosis risk management requirements for the design, construction, commissioning, operation, maintenance, repair, replacement and expansion of new and existing buildings, as well as their water systems and components. In Canada, there are five confirmed cases of Legionnaires’ disease in Dartmouth, NS, in a multi-level apartment building. At press time, the Nova Scotia Health Authority had confirmed the death of one of the patients. Previous cases in Canada include a 2012 outbreak in Quebec City, which killed 13 people and infected 170 others. In addition, an outbreak in a Toronto, ON nursing home in 2005 resulted in 21 deaths. Underwood said that ASHRAE is continuing its work on getting the full standard adopted in New York City and in other locations. For more on outbreaks associated with building potable water systems, see p26. www.ashrae.org SKILLED TRADES COLLEGE INTRODUCES PLUMBING PROGRAM Vaughan’s Skilled Trades College (STC) is launching its first formalized plumbing apprenticeship-training program.

Déjà vu, all over again BY IAN MCTEER

HVAC contractors in Canada know very well that the bulk of their time is spent preparing for, or dealing with winter. One of the most important requirements for any heating system is maintenance. Every device, and the distribution system it connects to must be inspected every year. The annual preventive maintenance (PM) service call provides an opportunity to sell new equipment, accessories and services. Modern heating and cooling systems that are AHRI rated and matched combinations, when properly specified, installed (including commissioning) and maintained (PSIM), will provide reliable service for many years. Another benefit of PSIM is reduced greenhouse gas emissions, not only from the HVAC system, but from the fleet of service trucks running around making unnecessary service calls.

SAFETY AND PERFORMANCE The primary reason for maintenance is to prevent failures. But, before a tool or gauge is connected to any heating appliance, there is a host of safety checks that must be performed to ensure fossil-fueled appliances are capable of working safely (see Steps 1 to 13). Code requirements, municipal by-laws, manufacturer’s instructions, insurance company rules and fuel distributor regulations can all make the modern PM task complicated. Each type of appliance will have its own set of rules and regulations. When an HVAC contractor maintains his or her own work, especially when it meets PSIM, maintenance should not be too difficult. However, it is the “other guy’s” job, encountered every day that needs a thorough maintenance inspection. Of course, technicians must be prepared to red tag unsafe appliances.

Step-by-step guide to preventive maintenance

Let us take a look at what a maintenance call to a residential high efficiency gas furnace might look like. We are going to look at the appliance and its accessories. Apart from all the necessary tools and instruments, the maintenance technician needs to have three things: knowledge, experience and a bright flashlight. Do not go near the appliance until its external infrastructure has been examined. Step 1: Upon arrival at the jobsite, ask the customer for permission to enter the yard in order to examine the vent terminal. Note the configuration of the terminal. Does it meet the gas code and manufacturers’ specifications for clearance to grade/windows/doors/inside corners/air intakes/gas regulator vents? Check for blockages or customer installed screening. Ask the customer why the screen was necessary. Check any other accessory vent termination, such as from a gas fireplace or HRV. Vertical chimneys used with older draft hood equipped or 80 per cent AFUE appliances must be visually inspected for deterioration, missing wind caps or blockages.

Clock the gas meter for each appliance to be sure input is correct.

During outdoor inspection, check the gas pressure regulator vent. It should be behind the meter and be clear of obstructions.

Check for proper vent termination per code and manufacturers’ instructions.

Inspect vertical terminations for plastic vents and metal chimneys.

I’LL BE BACK The Quebec singer-songwriter Gilles Vigneault wrote, “Mon pays ce n’est pas un pays, c’est l’hiver” (my country is not a country, it is winter). Winter is just around the corner, leaving just enough time for a couple of cooling system installations and a quick vacation. Otherwise, before Frankie MacDonald can say, ”Major blizzard to hit St. John’s,” HVAC maintenance will start all over again. Ian McTeer is an HVAC consultant with 35 years experience in the industry. Most recently he was a field rep for Trane Canada DSO. McTeer is a refrigeration mechanic and Class 1 Gas technician. 18

Step 2: Interview the customer. Ask about unusual sounds, odours, filter maintenance, poor heat distribution, too much or too little humidity, or furnace failures. Listen carefully for clues to system performance problems. Get permission to do a room-by-room check looking for open floor registers and blocked return air grilles. Ask if the appliance installation instructions are available for reference, if necessary. Step 3: Locate the thermostat. Depending on the existing thermostat, this would be an ideal time to offer the customer an upgraded thermostat. Get the old mercury bulb or battery operated control out of there – no more batteries to the landfill. Several manufacturers offer WiFi thermostats that communicate with a relay panel capable of operating just about any type of heating device. Most of these controllers have a test mode, a diagnostic screen with a history of events, a cycle rate screen showing burner or AC runtimes, and improved continuous fan control. Check the diagnostic log for a history of events if such a device is already installed. Ask the customer how any indicated failures were resolved. Step 4: Move to the appliance location. On the way, inspect the horizontal venting (looking for sags, leaks, vent pipe running level, homeowner caused damage) and the gas pip-

ing. Typically, plastic vent pipe must have support every three or four feet and be continuously sloped toward the furnace at 0.25 in. per foot. Step 5: The furnace room is where things get busy. Look at the number of appliances in the room. Determine where they are getting their combustion air. Many gas and oil-fired appliances continue to use indoor air for combustion. The gas code spells out specifically how much air is necessary, although some manufacturers’ instructions may be more “stringent” and must be followed in lieu of the code. Even though most sealed combustion appliances are approved to take air for combustion from within the building envelop, the tech must decide if there is enough air. Does the furnace room qualify as a “confined space” or not? Many homeowners have inadvertently put themselves at risk by enclosing the furnace room and restricting combustion air to the furnace or boiler and water heater. Step 6: Check vent connections at the appliance(s). Inspect the vertical chimney and its vent connectors. Inspect condensate drain piping – it must be connected to an open/ vented drain or condensate pump. Step 7: Move to the appliance(s). With the visual safety checks mostly done, maintenance of performance is the next

Does the existing thermostat allow the technician access to performance data? Be sure to check for diagnostic codes or a history of failures.

Inspect horizontal venting for leaks, sags, and improper slope.

Gravity drain lines must be clear, leak free and should terminate at an open/vented drain or condensate pump (pumping to an open/ vented drain or sump pit).

Burners must be clean – it only takes a tiny amount of lint in the cross-lighter to cause a lockout.

Why is this burner rusted on top? Check for contaminated combustion air – re-circulation of flue gas.

Step 9: Remove air filter, open the blower door and inspect the blower wheel. Remove the entire blower assembly if the wheel is dirty. Clean the blower wheel and the secondary heat exchanger. This is an ideal time to upgrade the homeowner to (at least) a MERV 11 air filter cabinet. Apart from the improved indoor air quality benefits, it is going to keep the important air handling components much cleaner. Low voltage wiring connections at the control board must be tight – look for signs of moisture in the blower compartment. Determine how it got there. Blow out the trap and drains and clean the condensate pump. Step 10: To do performance testing start the unit and listen for unusual sounds. Then, check gas pressure by performing supply side static and working pressure tests. Do a manifold test (remember to check both stages on a twostage model). Then, connect a dual input manometer to a sealed combustion furnace in order to verify pressure switch operation – if the start-up deep negative pressure is correct, then the venting system is clear. Then, check flame signal. After unit has run 10 minutes, do a temperature rise test. Check limit control operation by blocking off return air at the air filter. Step 11: Accessories. Clean the humidifier components and check operation. If customer has complained about humidifier operation, a more detailed inspection will be needed.

HOW TO

MANAGE PAYMENT

DATA A look at the widening scope of online payment services provided by financial institutions.

uch of what contractors do with software has to do with the handling of money. More than their peers in many other lines of business, contractors must monitor, record and attribute a wide, and sometimes unpredictable array of expenses. Getting it right often spells the difference between profit and a debilitating loss on a project. Furthermore, errors in reporting can have legal and regulatory repercussions. IT systems that manage these chores have become more powerful and, with the help of cloud computing, more affordable. Contractors, however, should also keep an eye on a parallel trend – the widening scope of online payment services provided by financial institutions. The charge has been led by credit card providers such as Visa and MasterCard. A decade ago, credit and debit cards were reserved for occasional purchases such as office supplies. Today, businesses are using these technologies increasingly for strategic expenditures that were formerly handled by purchase orders. The key is a myriad variations on the 22

traditional credit card that are collectively referred to as purchasing cards, or p-cards. Unlike their forbears, p-cards often involve no plastic at all, but 16-digit virtual card numbers that can be assigned for specific cost centres and then returned to a pool and re-assigned. The advantage for businesses is that they gain access to sophisticated online portals for monitoring and tracking expenses, assigning spending authorities and reporting for regulatory purposes. Essentially, this allows them to outsource various aspects of their e-procurement. “P-card use has expanded well beyond traditional plastic card usage by employees for the purchases of goods and services,” says Patrick Sulston, vice-president and senior business leader, commercial business development at MasterCard Canada. According to a 2014 North American study conducted by the RMPG research corporation, 18 per cent of businesses are using p-cards for strategic spending, 10 per cent say they will in the next year and a further 20 per cent will over the next three years. Mike Patterson, market management

– Wholesale Card Solutions at Citi Canada, says p-card adoption for very large contractors is in step with other industries, but that smaller providers are lagging behind the curve. “Typically, adoption slows in the construction sector as you move towards the small to mid-sized businesses,” he notes. Through the supporting management portals, the p-card systems give contractors access to a suite of expense-monitoring tools that allow managers to achieve a fine degree of control over the day-by-day spend. Essentially, contractors are getting “an expense product that can help them streamline their processes, and at the same time give them information that consolidates where they spend money and who spends what,” says Don Manson, senior manager for Commercial Cards at Scotiabank. Restricting purchases to preferred vendors – allowing for volume discounts – is one aspect of this level of control. An important feature is real-time reporting of irregularities. “You can use reporting tools to ensure compliance without process overload,” says Sulston. “Rather than having to monitor individual transactions, contractors HPACMAG.COM

“… p-card adoption for very large contractors is in step with other industries, but that smaller providers are lagging behind the curve.” can oversee and manage purchasing card programs by exception.” Much of the benefit to the bottom line, Patterson notes, is around speed. RPMG, for example, reports a 60 per cent-plus improvement in the time between order and the receipt of goods. All this helps contractors improve their working capital, making them more competitive. Contractors will find growing pressure from their customers to accept them. Since vendor fees finance the card systems, card providers are hoping that the appeal of a shorter payment cycle will encourage more contractors to sign on. To sweeten the pot, they have also begun to provide

volume discounts on large transactions. As well, payment could get even faster. A method called straightthrough processing, where payments are processed immediately upon invoice, is now being adopted by some organizations in the U.S. Another improvement on the receivables front is mobile technology for accepting traditional credit cards. One that is attracting a lot of attention is Square, a system that allows anybody to collect payments in the field using a credit card through a portable device that attaches to a computer or cell phone. A mechanical contractor, for example, could equip its service techni-

cians with these devices, enabling them to collect payment for service calls on the spot. “Square has many features perfect for contractors, such as a mobile invoicing feature and offline mode which allows you to take a payment even if you don’t have a reliable signal on your phone,” says Jenny He, communications lead, Square Canada. Like the card providers, Square provides online tools for tracking of transactions, which includes integration with QuickBooks and other popular software packages.

Paul Myers stands beside his company van outside of Lions Gate Hospital.

Plumber shares his good fortune Hospital redevelopment gets $25-million shot in the arm from HVAC entrepreneur.

aul Myers, owner of Keith Plumbing and Heating Co. Ltd. in North Vancouver recently created a media flurry when he donated $25 million to Lions Gate Hospital Foundation in Vancouver, BC. Myers’ gift, which is the largest single donation made to a hospital foundation by an individual in British Columbia’s history, will support a redevelopment of the Lions Gate Hospital site. “This is an extraordinarily generous gift from an exceptional person,” said Judy Savage, Lions Gate Hospital Foundation president. “It marks the first step in addressing the challenges from Lions Gate Hospital’s aging infrastructure. This donation is truly representative of the incredibly generous community we have here on the North Shore.” “I’m just a plumber who worked hard and had some good luck in my life,” said Myers. “When I thought about where I could have the greatest impact, I immediately thought of Lions Gate Hospital. I learned about the impact the Foundation is having and its excit-

ing plans for the future and knew this is where I wanted to make a difference.” Plans for the redevelopment of the Lions Gate Hospital site have been under discussion for the last five years with more detailed planning involving staff and physicians beginning a couple of years ago. Myers and his company have a rich history in the North Shore area. Myers has lived in the area for over 78 years. Keith Plumbing and Heating opened its doors in 1911 when the City of North Vancouver was just four years old and on the verge of a building boom. Known as “The City of Houses”, North Vancouver was fertile ground for development and the new residential plumbing contractor expanded as homes on the North Shore became increasingly numerous and sophisticated. The company incorporated as Keith Plumbing and Heating Co. In 1949 changing consumption patterns in the early fifties saw the company proactivley add a selection of household appliances to its range of products and services. The company history indi-

cates that “at one point you could walk into their showroom and purchase a new television set or a stateof-the-art electric stove.” Myers joined the company in 1954 as a plumbing apprentice. By 1970, the appliances were gone, Keith Plumbing and Heating Co. was doing $350,000 a year in business, Myers owned the company, and its tradition of staying on the leading edge continued. The company has transformed from a residential plumbing contractor to one of BC’s and the Yukon’s largest mechanical contractors employing up to 200 people. Specializing in plumbing, heating, ventilation and air-conditioning for hospitals, laboratories and major construction projects, Keith Plumbing and Heating Co. has been a partner in projects throughout BC and the Yukon since its inception. Myers also owns Keith Panel Systems and Keith Panel Systems USA Ltd. A recipient of the Lifetime Achievement Award from the Vancouver Regional Construction Association, Myers is a former director of the Construction Labour Relations Association of BC (CLR) and the Mechanical Industrial Relations Association (MIRA). Health care is one area in which Keith Plumbing and Heating has been particularly successful. Contracts include Kamloops Hospital, Royal Jubilee in Victoria and the Hope Centre for mental health. “We have done more hospitals than any other contractor in BC,” said Myers. When asked to sum up his reasons for choosing to give so much back to his community, Myer’s answer is simply, “Well, I can’t take it with me.” In recognition of Myers’ gift, Lions Gate Hospital’s South Acute Tower will be named the Paul Myers Tower. Representative signage will be installed on the west side of the tower by the end of the year and in the meantime, a bio plaque and door signage will be installed at the tower’s 13th Street entrance.

MYTHS & MISCONCEPTIONS Understanding the true nature of outbreaks associated with building potable water systems. By Tim Keane

ith the release of ANSI/ ASHRAE Standard 1882015 Legionellosis: Risk Management for Building Water Systems, an often ignored and serious issue associated with building potable water systems is getting a lot of attention. A common misconception is that legionnaires’ disease (LD) outbreaks are caused almost exclusively by cooling towers or HVAC systems. This is not true. A significant amount, if not a majority of LD outbreaks, are actually caused by potable water systems. Recent outbreaks in Canada that received a lot of press include an apparent potable water outbreak in a Nova Scotia apartment building, and cooling tower related outbreaks at a Scarborough nursing home and one in Quebec City. Cases of LD associated with cooling tower outbreaks are typically identified because there is usually a high rate of associated illness with dozens to hundreds of people getting sick in a short period of time. Outbreaks associated with potable water are just as often not identified because these outbreaks can be as few as a handful of people getting sick over days or weeks or longer.

HPAC | OCTOBER 2015

A study in 2003 tested pneumonia cases admitted to 15 hospitals across Canada. The results were very interesting. Of the 850 pneumonia patients tested 28 (3.2 per cent) had LD. What was very interesting in this study was that Western provinces, which were thought to have a lower incidence of LD, had a higher incidence rate with 11 cases out of 277 patients (3.9 per cent) compared to Eastern provinces with 17 out of 573 (2.9 per cent). Another common misconception is that because LD does not appear in the news too often, the number of cases must be declining. In fact, the annual incidence of LD cases has increased dramatically. A 2011 CDC study found that U.S. LD cases increased 217 per cent from 2000 to 2009. Another CDC study, a study of waterborne diseases associated with drinking water and non-recreational water from 2009 to 2010, found that LD accounted for 58 per cent of outbreaks, 42 per cent of illnesses, 96 per cent of hospitalizations, and 100 per cent (all) deaths. Litigation associated with Legionella cases has increased dramatically over the past decade as well. I have been

involved in many LD litigations and in most of these plumbing engineers, contractors and builders were brought into the litigation. As stated above, over the past decade this has become a real and growing issue. Another all too common misconception is that designing plumbing systems to reduce the risk of Legionella means extra costs and less efficient systems. In fact, the same items that are recommended for engineering design to reduce the risk of Legionella colonization are also recommended by most engineering experts for water and energy savings. If you are surprised by any of the information here, do not feel badly. The lack of awareness regarding this serious issue is pervasive in public health, the healthcare industry, non-healthcare industries, associations, code development and trades. There are very good Legionella guidelines, legally recognized ‘standards of care’ published on that are more than a decade old. These U.S. ‘standards of care’ include OSHA (1998), ASHRAE 12-2000 (2000), Joint Commission (2001) and CDC (2003), to name a few. All of these Legionella guidelines are scientifically based and are useful and effective tools for Legionella control in plumbing design. continued on p28

< PLUMBING continued from 26 “ Outbreaks associated with potable water are just as often not identified because these outbreaks can be as few as a handful of people getting sick over days or weeks or longer.” The new ANSI/ASHRAE Standard 1882015 Legionellosis: Risk Management for Building Water Systems will have an immediate impact. It will help increase awareness in the plumbing industry and will hopefully result in beneficial steps to reduce the plumbing industry’s risk of negligence litigation associated with this issue. The long term result should be improved plumbing codes, plumbing system design and plumbing products that reduce the potential for Legionella to grow in plumbing systems. Hot water heater manufacturers ad-

dress the ‘failure to warn’ scald negligence risk associated with their product by ensuring every hot water heater manual has a full page or more on scald risk. But LD issues in the U.S. have been largely ignored, despite being associated with many different plumbing products, especially those that temper the water, reduce flow, destroy disinfectants, or allow potential for cross-connection between hot and cold water. The plumbing industry is much more concerned and aware of scalding issues even though rates of

potable water system issues associated with scalding are almost insignificant when compared to LD. Some plumbing component manufacturers aware of the market opportunities are improving existing products and developing new products to address these issues. Tim Keane is with Legionella Risk Management, Inc. He is internationally recognized as an expert in Legionella control and has investigated numerous legionnaires’ disease outbreaks in North America. An original member of ASHRAE 188 committee, Keane has authored numerous papers and presented at scientific and industry meetings on the issue.

orth Americans are cautious when it comes to changing bathroom trends. New textures and bright colours often send consumers running to comfortable hues they know well – white and grey. Though these tranquil shades are, according to the National Kitchen & Bath Association (NKBA), the dominant colours for today’s bathrooms, it does not mean that current designs and products lack bold creativity. Bathroom faucets, fixtures and accessories are daring in other ways, moving towards a sleek appearance and natural materials.

Customers are also wanting modern luxurious amenities like steam showers, heated floors and anti-fog mirrors, so a modern design is not too far fetched. In fact, Garry Scott, vice president of wholesale marketing and brand development at Moen, says that Moen’s annual consumer research shows that 41 per cent of Canadians prefer modern décor for their bathrooms. Melissa Tossell, interior designer at Sanura Design in Toronto, agrees. She says that customers like their bathrooms to appear high end. By choosing geometric shapes and using

strategic bursts of colour, consumers can achieve a high end, modern look. Faucets and handles are characteristics that can give bathrooms a sleek modern feel without undergoing a full blown renovation. Scott explained that some of Moen’s products have interchangeable handles, which allows consumers to easily modernize their fixtures without replacing them.

TWO-PRONGED DESIGN Brad Campeau, sales manager at Masco Canada says, “consumers are trending towards a contemporary design aesthetic with clean lines that promote simplicity, harmony and balance.” The NKBA has also found contemporary design to be the most popular trend for North American residential bathrooms. Adding that the once oh-so popular tub and shower combo has officially split-up, with free standing tubs and walk-in showers taking their place. “Shower and tub trims are not just a matter of function, but about creating a centerpiece for the bathroom,” Campeau says.

The emphasis is not solely on water conserving products, like low flush toilets, anymore. Now it is also on products that reduce waste by having a long lifespan and products that are not harmful when disposed of. “Natural stone is very popular right now, it is a higher end, quality product,” Tossell says.

TIME IS OF THE ESSENCE Perhaps an overlooked, but popular trend is timeliness. People want their

products and they want them fast, and luckily manufacturers are designing products with immediacy in mind. André Deland, vice president of product development and marketing communication at MAAX, says that being able to start and finish installation in a single day is an attractive option for both customer and contractor. Customers get their product quickly, and contractors are able to work with more clients and therefore complete additional jobs. Using different product materials, such as alternatives to tile or easily serviced plumbing systems, saves time and offers “piece of mind” to all parties involved. With these types of innovations, consumers can technically and aesthetically renovate their bathroom on a sensitive buget.

Tubing depth matters!

It is time to find better ways of ensuring that tubing and reinforcing mesh end up near the mid-height of the slab. BY JOHN SIEGENTHALER

nyone who has installed hydronic floor heating has likely watched as his or her neatly placed tubing circuits get buried in concrete. Sometimes the tubing and reinforcing mesh it is attached to gets lifted into the thickness of the slab as the concrete is placed. Other times the masons trample over the tubing and mesh as if it is not even there.

DOES TUBING DEPTH MATTER? Unlike relocating a sensor or unsweating a pipe, there is no chance of changing tubing depth once that screed slides over the concrete. The slab’s performance over decades of future service life is now fixed. The irreversibility of the situation should give us pause to consider if we are installing the tubing in the best manner possible. If the tubing depth does not have much of an effect on performance, why worry about it? However, if tubing depth does significantly affect performance why be ignorant of it? Why sacrifice performance to a detail that adds very little, if anything, to the installation cost? There are several ways that tubing depth should affect the performance of a heated slab: • The deeper the tubing, the greater the thermal resistance between it and the floor surface. The higher the thermal resistance in the path of heat flow, the higher the water temperature must be to achieve and maintain a given rate of heat transfer. • The closer the tubing is to the bottom of the slab the greater the underside heat losses should be. • When the tubing ends up near the bottom of the slab more of the slab’s thermal mass is above the horizontal plane at which heat is being added. This increases the time required to warm the floor surface to normal operating temperatures following a call for heat. It also lengthens the cool down time after heat input is interrupted by system controls. A fully “charged” slab can hold several hours worth of heat that will continue to flow into the space as long as the air temperature and/or interior surface temperatures are cooler than the floor surface. This can be a real problem in buildings with significant internal heat gains from sunlight or other sources. 34

HPAC | OCTOBER 2015

Considering these facts, it seems intuitive that placing the tubing higher in the slab will improve its performance. The harder questions to answer are: 1. How much is performance affected by tubing depth? 2. Is the change in performance worth the necessary jobsite oversight to ensure it happens?

NUMBER CRUNCHING The answers to these questions require credible numbers. One way to get them is through specialized software known as finite element analysis (FEA). This software allows a physical situation to be mathematically modeled and simulated. The calculations FEA software can do in a couple of seconds are far beyond what any person could attempt to solve through manual methods. One of the FEA models I constructed is shown in Figure 1. It consists of a four-inch concrete slab sitting on one-inch thick extruded polystyrene insulation (R-5 ºF•hr•ft2/Btu), and covered by 3/8 in. oak flooring. The latter is assumed to be perfectly bonded to the top of the slab. The tubing is assumed to be spaced 12 in. apart. Several versions of this model were used to simulate tubing at different depths in the slab. Each time the model was run it determined the temperature at hundreds of points within a small region of the slab including points spaced 1/2 in. apart along the floor surface. HPACMAG.COM

Average circuit water temperature (ºF) with tubing at ½ slab pth 95F 120F

Average circuit water temperature (ºF) with tubing at bottom of slab 102F 134F

These results imply that the average water temperature in the circuit has to increase about 7F to yield an output of 2 15 Btu/hr/ft if the tubing is located at the bottom of the slab. The average water temperature in the circuit must be 2 about 14F higher to yield an output of 30 Btu/hr/ft with the tubing at the bottom of the slab. Can the system’s heat source provide the higher water temperatures required by the deeper tubing? If that heat source is a conventional boiler, this change in water temperature would likely have a very small (but none-the-less undesirable) effect on boiler efficiency. However, if the heat source was a condensing boiler, solar thermal collector array or heat pump, this change in required water temperature would have a more pronounced negative effect on efficiency, as well as the heat gathering ability of the solar collectors or heat pump. Higher water temperatures in the tubing also mean reduced capacity through mixing devices, higher piping heat loss and higher underslab losses, all of which are undesirable.

I also wanted to see how tubing depth effects heat output for 21 uncovered concrete slabs. The FEA model was easily modified 19 to turn the 3/8 in. oak flooring into 3/8 in.Heat thick concrete and the output based on 1/2" PEX tubes ! spaced 12" o.c.in 4" thick ! 17 bare concrete slab! output at simulations were rerun.

tubing subgrade

Figure 2 shows the isotherms (e.g., line of constant temperature within the slab and surrounding materials) that are generated by the FEA software. When the FEA model was run for several tubing depths the following trends were observed as the tubing is placed deeper in the slab: 1. The floor surface temperature directly above the tube decreases due to the greater R-value between the tube and the surface. 2. The difference between the floor surface temperature directly over the tube and that half way between adjacent tubes decreases. This is a desirable effect because it makes the floor surface temperature more “homogenous.” 3. The area under the surface temperature profile curve changes with tube depth. This implies that the upward heat output from the floor changes as tubing depth changes. Using the temperature data from several simulations, I estimated the heat output from the system for water temperatures of 100F and 130F. In each case, heat output increases as the tubing is lowered through the upper portion of the slab and decreases as the tubing gets deeper. This implies that there is an optimal tube depth where the slab delivers maximum heat output. The simulations I ran suggest it is about ¼ of the slab thickness down from the slab surface. However, this depth could vary depending on flooring resistance and other factors. I also used the FEA results to determine the average water temperatures required to deliver heat outputs of 15 and 2 30 Btu/hr/ft . The results are shown in Figure 3.

< HYDRONICS continued from 35 The results again show that heat output decreases as the tubing is placed lower in the slab. The highest output for the simulations I ran occurs when the tube is centered about ¾ in. 2 below the slab surface (about 25.1 Btu/hr/ft at 100F water temperature). Lowering the tube so that its centre is two inches below the slab surface (e.g., tubing centred on four2 inch slab thickness) reduces output to 23.8 Btu/hr/ft . These changes are relatively small. However, look at what the simulation predicts when the tube is located at the bottom of the 2 slab. Here the output is only 17.8 Btu/hr/ft . That is a 25 per cent decrease in upward heat output compared to when the tubing is centred in the slab’s thickness. The only way to compensate for this would be to increase water temperature several degrees Fahrenheit. I also looked at downward heat loss as a function of tubing depth. When water temperatures are adjusted (as shown in Figure 3) to allow tubing placed at the bottom of the slab to produce the same upward heat output as tubing centred in the slab, downward heat loss increases by about 10 per cent.

OTHER CONSIDERATIONS There are factors other than thermal performance that have a bearing on tubing depth within a slab. One of them is protecting the tubing near sawn control joints. The depth of

Figure 5

such saw cuts is typically 20 per cent of the slab thickness. I prefer to keep the tubing near the bottom of the slab at such locations to give the blade a wide berth as it passes over. A typical detail is shown in Figure 5. Another consideration is penetrations by fasteners used to secure equipment to the slab. In most cases it does not make sense to leave all the tubing at the bottom of the slab just to accommodate what might be a future bench or lift post. Find out where such equipment will be placed and keep the tubing several inches away from where the continued on p38

WHAT DOES THIS MEAN? Is finite element analysis guaranteed to predict reality with 100 per cent accuracy? No. There are hundreds of possible variations on factors such as soil temperature, flooring resistance, tube spacing and so on, that make it hard to draw generalized conclusions based on a few simulations. Still, for the limited simulations I ran, the predicted upward heat outputs agreed fairly well with other sizing tools used for system design. The predicted increase in water temperature required for tubing at the bottom (rather than the centre) of the slab is both believable and significant. The 10 per cent increase in downward heat loss caused by higher water temperatures in bottomed-out tubing also seems reasonable. Keep in mind that these results are also based on steadystate conditions. They do not predict the consequences of the longer response times associated with deeper tubing. In buildings with significant and often unpredictable internal heat gains, this longer reaction time will surely lead to wider temperature swings and compromised comfort.

Considering all these tradeoffs perhaps it is time we all find better ways of ensuring that tubing and reinforcing mesh end up near the mid-height of the slab, (except under any sawn control joints). For products such as “knobby” foam panels, or plastic staples that clamp PEX directly to the underslab insulation, manufacturers should provide accurate thermal performance data that accounts for this tubing placement. Be sure to make your requirements clear within plans and specifications. It is also worth having a discussion of these requirements with the “accountable” person overseeing the concrete crew. Make sure they know that tubing depth does affect system performance. Do this several days before the pour, not while the first concrete truck is backing down the driveway, so there is no excuse for being unprepared.

Understanding and measuring energy transfer

It is crucial to calculate the load when designing a heating system. BY GILLES LEGAULT

o design an energy efficient and comfortable heating system, it is important to understand and measure the energy transfer. In short, we have to replace the energy leaking through walls, ceilings, floors and openings in the building envelop. Since the energy always seeks a balance, it will move from a high-temperature area to a lowtemperature area. This transfer will occur by conduction, convection or radiation. If the energy input exceeds or does not meet the system’s energy loss, its efficiency will decrease, as will the comfort (and satisfaction) of the occupants. We must calculate the amount of energy that will find its way through the energy shell using the following formula: Q = A (k/x) (∆T) where: Q = heat transfer rate through a given material k = conductivity of the material (Btu/F∙hr∙ft) x = material thickness ∆ T = temperature differential on both sides of the material (˚F) A = surface of the material (sq. ft.)

POINTS TO CONSIDER These calculations are essential when designing a heating system to ensure it will not be over or undersized, which means it will be efficient and will provide room comfort. In addition, these calculations are required by the CSA B214 standard, which has been part of the National Building Code since 2010. The 4.6.2 (a) point of the standard says that the design load heating calculation – in kWh (Btuh) – must be performed in each single room. For contractors who say that they do not have time to perform load calculations, there is great software available, some of which use the CSA F280 Standard Form Heat Loss Gain Calculation standard. Think about it. How can we determine the supply temperature and the required flow rate of each zone if we do not know what the load is? While some contractors choose the oversizing “strategy” to avoid complaints, the lack of comfort and excessive operating costs would generate even more unpleasant and expensive complaints, not to mention the damage to your business’s reputation. 42

HPAC | OCTOBER 2015

Heating system design should take into account the replacement of the energy leaking through walls, ceilings, floors and openings in the building envelop.

We should also be aware that identical house projects, such as those we saw in the 1970s, no longer exist. Thus, the heating/cooling system design of a particular house does not apply to the design of another similar (in appearance) house. Today, every home is different and the slightest change in the building envelope and occupant behaviour can make a big difference in its heating load.

ROOM-BY-ROOM EVALUATION Why does CSA B214 require room-by-room load calculations? Just as the load of each house is different, so is the load of each room. For example, consider a one-storey slab on grade house with two identical 100 sq. ft. bedrooms. One of these rooms has two outer walls, while the other one has only one. Assuming that the thermal resistance is: R20 walls, R40 ceilings, R10 slab, and that each room has a 4 ft. x 4 ft. window, the room with two outer walls will need 27 Btuh/sq. ft. while the one with one outer wall will only need 20 Btuh/sq. ft. If the contractor has chosen the 25 Btuh rule of the thumb value, it is easy to figure out that the heating system for one room will be undersized and the other one will be oversized. In both cases the customer will not be happy. There is no good reason to undertake the installation of any type of heating system without a prior calculation of energy loss. These calculations ensure our customers will be comfortable and happy. In addition, they allow us to meet CSA B214 and comply with the National Building Code.

Oil heat professionals tackle tough issues

ttendance numbers were up for the 2015 CleanerHeat Symposium, which was held at the Halifax Marriott Harbourfront Hotel in June. Code concerns, the labour market, market share and insurance were top of mind at the event. Close to 200 attendees took in the full speaker program, along with social events at the two-day Canadian Oil Heat Association conference. Session speakers included: Sylvain Villeneuve, of Vilco Ltd. and Superior Tanks Ltd.; Bill Fligg, of Petro Buster Inc.; Matthew Gardner, of Wilms and Shier Environmental Lawyers LLP; Paul Rew, of Rubicon Environmental Inc.; Paul Seager, of HH Angus and Associates Ltd.; COHA president Stephen Koch; Michael Lio, of BuildABILITY Corporation; and Don Huff, of Environmental Communications Options. At the manufacturers roundtable, participants from Riello, RW Beckett, Granby Steel Tanks, Roth and Vilco discussed how to improve the public’s perception of the oil heat industry and make headway in the new home market. Oil equipment capacity was identified as a major concern. “Houses are a lot better insulated. This leads us to a point where heat loss is very low,” said Michel Beaulieu, vice president sales, Canada, Roth Industries. “In the future we’ll have

to have more efficient heating equipment and smaller capacity,” emphasized Beaulieu. He referred to CSA F280 and noted that residential heat loss has been halved. Panelists agreed that there is a lot of old, inefficient oil equipment out there. “We get Bernie Jackson, faculty member, heating, refrigeration and calls from contractors looking air conditioning technician for burner parts from 20 years program at Humber College, ago and more,” said Kevin Bond, reported that the school has to turn students away from its president, Riello Canada. “Why two-year OBT3 program. are they fixing that appliance?” There is shared responsibility for the issues around selling new, more efficient equipment, much of which was on display at the symposium trade show. “There’s responsibility all the way along the supply channel, including the homeowner,” said Jonathan Beckett, vice president of sales and marketing with R.W. Beckett. The 2016 conference will be held in Charlottetown, PE, at the Delta Prince Edward, from June 7 to 9. www.coha.ca

Winners all around at Modern Hydronics -Summit 2015

A sell out crowd enjoyed a robust speaker program and a host of hydronics products at HPAC’s September 10th flagship event.

lose to 400 people, including exhibitors, delegates and speakers, headed to the International Centre in Mississauga, ON on September 10 to be immersed in hydronics at Modern Hydronics-Summit 2015. In addition to the change in venue for the event, sessions were consecutive so attendees were able to take in all of the speakers, and have time to check out the more than 50 hydronics exhibitors. Robert Bean and John Siegenthaler opened the show with their take on the top 10 trends in hydronics. Always entertaining and insightful, Siggy & the Bean was a filled-to-capacity event. You have heard of BTU metering but what is it and what does it mean to your hydronics business? Mark Evans explained all that and more in his session BTU metering–Canada’s future opportunities for the downstream measurement of energy consumption at point-of-use. An afternoon panel session titled Hydronics Training and Certification: Where do we go from here?, had representatives from the Ontario College of Trades (OCOT), industry associations and other stakeholders. Bob Onyschuk and Royden Trainor of OCOT, Martin Luymes of HRAI, David Graeme of Belyea Bros. and Mike Wills, Canadian Hydronics Council Ontario Region chair, discussed where their organizations are at in terms continued on p50 HPACMAG.COM

In the show’s opening session, John Siegenthaler (l) and Robert Bean shared their perspectives on trends in the hydronics industry.

Mike Miller (l) of Taco and Steve Goldie of NEXT led an engaging session on reducing distribution piping.

The customer is always right – well not always but contractors have to learn to create high performing buildings within that framework said Robert Bean in his Summit presentation.

Mark Evans of Viega explains BTU metering and what it will mean to the mechanical contracting industry in terms of opportunities and threats.

John Siegenthaler (l) presented Rob Carmichael with a Bacharach Portable Combustion Analyzer.

The DeWalt 20V MAX Lithium Ion Reciprocating Saw was won by Brendon Aldridge, shown here with Robert Bean(l).

Keep it simple was the theme of John Siegenthaler’s keynote address, which wrapped up the speaker portion of the Summit. OCTOBER 2015 | HPAC

of resolving who should do hydronics, and what training is required. Your favourite hydronics problem solvers, Mike Miller and Steve Goldie took an in-depth look at distribution piping. The message delivered by Miller and Goldie was that smart design can save you time and labour, and deliver a top of the line system to the customer. The entertaining presentation showed delegates how to make that happen. Balancing the needs and wants of your customer with good building practices is always a challenge. Achieving high performance when under high pressure from clients is possible and Robert Beanâ&#x20AC;&#x2122;s session: An Integrated Hybrid System for the Great Lakes Region, demonstrated this. John Siegenthaler wrapped up the speaker portion of Modern HydronicsSummit 2015 with Simplifying Hydronic Systems Without Sacrificing Performance. As Siegenthaler said, why build the space shuttle when our clients need a Cessna? Contractors and installers attending the session learned how they can ensure that consumers view hydronic heating as an affordable, efficient and understandable technology; something that they want in their home or place of business. By all accounts Modern HydronicsSummit 2015 was a hit, particularly for Rob Carmichael, a technician with Brayâ&#x20AC;&#x2122;s Fuels Limited of Newmarket and Brendon Aldridge, owner of Dr. HVAC Ltd. in Brampton, ON. Carmichael and Aldridge were the lucky winners of the tool draws during the event. Modern Hydronics Autumn 2015 at www.hpacmag.com features many of the presentations.

ver 400 members of the public showed up at Reid’s Heritage Homes’ grand opening for its newly constructed Net Zero Energy home in Guelph, ON, on September 19. The Net Zero Discovery Home is the first to be completed as part of a national demonstration project to prove that Net Zero homes can be built on a community-level scale. Features of the home include: advanced heating and cooling capabilities, with a modulated delivery system and floor zoning; 33 solar panels on the back roof; hybrid heat pump water heater; drain water heat recovery system; insulated and airtight design provide an advanced envelope style; and triple pane

windows. A second Net Zero home, built beside the Discovery Home, offers 1775 sq. ft. of living space and is listed for sale at $523,525. The goal of the project is to make Net Zero Energy homes, which can produce as much energy as they consume on an annual basis, fully accessible and affordable to all Canadians. Reid’s Heritage Homes, which is building five homes as part of this project, is one of five builders that were selected to participate in the national project. At least 25 Net Zero Energy homes will be built in Nova Scotia, Québec, Alberta, and Ontario. This total will almost double the amount of Net Zero Energy homes currently in Canada. The project is funded in part by the

ecoENERGY Innovation Initiative (ecoEII), with contributions from each participating builder, industry suppliers and Owens Corning Canada. Reid’s Heritage Homes’ first five Net Zero homes are being built in the builder’s signature family community of Westminster Woods, located in Guelph.

WHAT IS GOING ON IN THE WORLD OF

SUPERMARKET REFRIGERATION?

t comes as no surprise to anyone that supermarkets are under pressure to embrace green. As applied to the refrigeration portion of a supermarket this translates into: reduce carbon footprint, lower Global Warming Potential (GWP), reduce refrigerant charge, reduce electrical consumption and increase efficiency. Letâ&#x20AC;&#x2122;s discuss the GWP portion. Figure 1 compares refrigerant usage in a sample of over 8000 existing U.S. supermarkets and how that usage trends between 2007 and 2013. As one would expect, it shows a dramatic move away from R-22. This is a reflection of a two pronged effort to reduce R-22 use in supermarkets; new stores transitioning to refrigerants other than R-22, and existing R-22 supermarkets converting to a lower GWP alternative. It is no surprise to see the percentage of stores using R-22 decrease. It is equally of no surprise to see the use of R-404A increase. What might appear surprising on the surface is R-407Aâ&#x20AC;&#x2122;s appearance as a contender. The fact is that R-407A offers a good capacity com68

HPAC | OCTOBER 2015

parison to R-22 (approximately 103 per cent in medium temperature applications, and approximately 95 per cent in low temperature applications). In low temperature applications R-407A will have a significantly lower discharge temperature (approximately 60F) than R-22, reducing the need for capacity robbing demand cooling. Additionally, the mass flow requirements for R-407A are very close to R-22, meaning that there are no TEV or distributor nozzle replacements required when converting an existing R-22 system to R-407A. Finally, as a refrigerant that is out of patent, it has a wide base of distribution at very competitive prices. What might be a little more telling is Figure 1 Comparative refrigerant usage

the information in Figure 2, which is based on information provided by OEMs in 2012. Here you see that approximately 40 per cent of all new supermarket equipment is built for use with R-407A. This is a reflection of several major supermarket chains changing their refrigerant specification to R-407A. This certainly constitutes a trend towards using a refrigerant with a lower GWP. Remarkably, this shift towards R-407A (a lower GWP refrigerant) was done without government regulation. Even so, in the U.S., a presidential executive order was signed in 2013 directing the EPA to use Significant New Alternatives Policy (SNAP) to reduce emissions of HFCs. In response to that executive order, the EPA recently issued a final ruling that changes the status of certain refrigerants and their use in certain applications. Particularly targeted were R-404A and R-507, due to their relatively high respective GWPs of 3900 and 3922. Beginning January 1, 2017, both of these refrigerants will be banned from use in new store installations consisting of systems with more than one compressor (including multiplex compressor racks, distributed systems, secondary refrigerant systems, and so on). The same ban will apply to single condensing units, beginning January 1, 2018. In addition, any supermarket refrigeration system undergoing a refrigerant conversion will be banned from using R-404A/R-507 beginning July 20, 2018. This ruling does not affect existing R-404A/R-507 systems, nor does it require a phase out of the importation of new production of R-404A/R-507. While the move away from R-404A and R-507 now has the power and authority of the government behind it, the supermarket industry and the associated marketplace are continuing in their effort to anticipate future regulations. As such, there are two new refrigerants in the offing; R-448A (a HPACMAG.COM

REFRIGERATION > Honeywell product) and R-449A (a Figure 2 Comparative refrigerant usage in new supermarkets DuPont product). These are zeotropic blends that are somewhat similar to the current crop of R-22 alternatives, in that they are blended from the same R407A building blocks used in many currently available R-22 alternatives (R-32, R404A R507 R-125 and R-134A). Where they differ is that these blends also contain a percentage of one or both of the ultra low GWP HFO (Hydrofluoroolefin) refrigerants HFO-1234yf and HFO-1234ze. These two refrigerants look promising. In addition to a significantly lower GWP, they offer slightly higher capac- adding inefficiency to the system, the permarket to use carbon dioxide (CO2) ity and efficiency than R-404A.

The reduced load resulting from doors on cases allowed small charge systems to be a workable solution. In addition to using an environmentally friendly refrigerant, the relative simplicity of these systems eliminated a significant portion of the installation charge. The self-contained nature eliminated the need for large amounts of pipe to connect remote compressor racks to the evaporators and the necessary labour to do so. In addition, the hope is that the simplistic design will greatly reduce the maintenance expense. Should a catastrophic failure occur with the selfcontained unit, it can simply be replaced rather than repaired, not unlike a household appliance. Certainly the modern supermarket, with the amount of refrigerated product available to the consumer and the volume of refrigeration system capacity necessary to maintain the integrity of that product, has been a focus for sustainability from environmental agencies. Do not expect this to change. In fact, you can count on ever increasing regulations requiring the larger commercial ventures utilizing refrigeration equipment to be held to higher and higher standards. Whether you agree with the debate about global warming or not, there will be ongoing government regulation to ensure that businesses minimize their affect on potential damage to our environment.

< INDOOR AIR QUALITY

IN A

FIELD OF ITS OWN

Standard practice for evaluating residential indoor air quality concerns.

By Robert Bean

ndoor air quality (IAQ) concerns in residential buildings range from irritation and discomfort, to health problems as a result of unacceptable exposures to odours, particulate, gases, chemical and biological matter. For these reasons in the continuum of construction there will always be expanding prospects for IAQ solutions for firms that are interested in increasing their services and product offerings. Due to the intimate relationship between the health of the environment and health of the occupants, it is important that those interests are approached knowledgably through education, awareness and professionalism.

COMPLEX FIELD Let us start by stating IAQ is part of a comprehensive field of study referred to as indoor environmental quality (IEQ), which is coupled to an even bigger field of study in human factors and ergonomics. For those pursuing IAQ opportunities, it will become apparent that the field is the intersection of many studies with each of those being many layers deep. Specifically for buildings, IAQ stands 72

HPAC | OCTOBER 2015

as one of six primary terms within IEQ, expressed collectively as: IEQ = IAQ + ITQ + ILQ + ISQ + IOQ + IVQ where I = Indoor, Q = Quality A = Air T = Thermal

L = Lighting S = Sound O = Odour V = Vibrations

As one can see, it is incorrect to imply that IAQ stands alone as a proxy for IEQ as is sometimes mistakenly communicated even by experts from within the health and building community. For example, the U.S. Centers for Disease Control and Prevention (CDC) has stated, “Indoor Environmental Quality simply refers to the quality of the air in an office or other building environments.” This statement has been copied and restated by countless “authorities” and continues to be used even though the CDC has since corrected its definition. To bring the topic of separation to the discussion, an authoritative document, ANSI/ASHRAE Standard 62.2 Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings states,

“This standard considers chemical, physical, and biological contaminants that can affect air quality. Thermal comfort requirements are not included in this standard (see ANSI/ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy).” Translation: residential IAQ practitioners must be clear that ventilation, indoor air quality and thermal comfort are standalone studies. ASHRAE 62.2 defines IAQ as, “air toward which a substantial majority of occupants express no dissatisfaction with respect to odour and sensory irritation and in which there are not likely to be contaminants at concentrations that are known to pose a health risk.” The publication also states, “While acceptable IAQ is the goal of this standard, it will not necessarily be achieved even if all requirements are met.” Some reasons for this include, diversity of sources and contaminants; range of susceptibility in the population; and perception and acceptance being affected by temperature, humidity, noise, lighting and stress. Clearly IAQ is not just a matter for service providers defaulting to filtration and HPACMAG.COM

(de)humidification upgrades, in fact these solutions can often mask the source of the IAQ problem. I have addressed much of the above in previous articles in HPAC, so why regurgitate the message? I hope to underline for HVAC professionals that one has to be clear in one’s objectives – understanding that an IAQ inspection would include addressing odour and irritation complaints due to contaminants. But how do you deal with the tricky, and often subjective, topic of smells? Also, what is an irritant and does that require the knowledge of a medical professional? How about contaminants? How do these differ from pollutants and toxicants? Does it matter?

INVESTIGATIVE PROCEDURE One authoritative document that offers up a nice serving of guidance, including investigative flow charts, questionnaires and check lists, is ASTM D7297-14 Standard Practice for Evaluating Residential Indoor Air Quality Concerns.1 It says the, “Characterization of IAQ concerns and identification of their underlying causes require systematic observations and measurements of the indoor environment, its occupants and contaminant sources.” The procedures in the ASTM D7297 include a three phase investigative procedure from telephone and face-to-face interviews, to follow up protocols for site investigations, assessments and measurements. The results of these exercises then serve as the basis for recommending corrective measures. The Standard has several “pause points” throughout the process to allow investigators to take the time to “step back to assess all field observations and data that have been collected at any given point to determine or postulate potential causes.” This cannot be overemphasized as inexperienced or less professional service providers frequently want to solve problems using their skill set or with products in their in-

ventory. In fact, during a pause point there may be cause to cease the investigation and call in another specialist. In part this is the reason the Standard states, “Implementation of procedures given in this standard requires the investigator (or investigative team) to have adequate background in several areas: general principles of IAQ; interviewing techniques; building design and construction practices; basic understanding of heating and cooling systems and appliances; use of IAQ measurement equipment; interpretation of IAQ data; and technical report writing.” One of the areas of concern I have for the Standard has to do with its suggestion that investigators, “could benefit from a review of existing medical records.” Whilst in the hand of the right person this may be a true statement, it is impossible to imagine how someone without a medical background and the obligatory ethics could or should be in possession of someone’s medical records. How this passed through the ASTM committee is as much of a mystery for me as Ross Perot or Donald Trump running for the presidency. Despite this glaring inclusion, it does recover by bringing awareness to the hazards investigators can be exposed to during an investigation. The chemicals, varnishes, paints and fuels that people store in unmarked containers, along with clothes and bedding contaminated with mould, rodent and insect feces and bacterial contaminants found in bathrooms and kitchens and bedrooms, are all sufficient to call in public health officials. Those circumstances are not the place for someone who just wants to upgrade an air filtration system regardless of its benefits. However, if the IAQ concern is based upon occupant-based odours and particulate or visible signs of soot or back drafting then it is likely the health authorities can stay home and the filter catalogue and combustion and pressure instruments can come out.

It is not possible to cover all the potential opportunities afforded to the IAQ industry in this space. Filtration solutions, humidity control, combustion analysis, air flow, velocity, duct leakage and system balancing, along with thermal comfort complaints of draft, inconsistent temperatures and cold floors are routine service call issues. To move into the IAQ industry and beyond what is currently in your technicians’ skill sets, and beyond the capability of the products and tools found in your service vans, you need to start your own education program. Begin with a study of ASTM D7297. Though the document is an invaluable resource for identifying potential causes (what to look for) and can be used as the basis for recommending corrective measures, it is not a “how to correct” guide. Such corrective measures ultimately lay in the hands of the practitioner based on his or her experience and skills.

Cross Connection Control Bad And Ugly Photo Contest wrap up

n the world of potable water protection and backflow prevention, a certified specialist tester or inspector will find cross connections that are controlled, and in too many cases, a bad cross connection with no control. In a bid to address problem installations and improve education, the Western Canada Section American Water Works Association Cross (WCSAWWA) Connection Control Committee (CCC) launched its Bad and Ugly contest in 2014. The 2014-2015 Bad and Ugly backflow contest received an enthusiastic response with 20 entries and the winners were recently announced. The WCSAWWA Cross Connection Control Committee judged the photo submissions. Three winners from across Canada were each presented with tools, compliments of Conbraco Industries, Watts Canada and Zurn Industries. Organizers are now calling for entries for the 2015-2016 contest. The WCSAWWA offers the following considerations for photo entries:

> Device selection > Hazard application > Device installation and orientation > Device height and access for testing > Device drain or lack of drain > Tag or no tag, test cock plugs or no plugs > Using test cocks for other purposes > Device or assembly broken up > Poor plumbing practices, supports, connections and others Entries must be received by April 1, 2016. Submission categories are active tester in the field and cross connection control inspector/regulator. Prizes will be awarded in May 2016. www.wcsawwa.net 78

Doug Kaupp (l), general manager — water, waste water and storm water, City of Lethbridge and Graeme Dennis (WCSAWWA CCC member), cross connection control officer, environmental utilities, The City Of Medicine Hat (r), with Watts pressure differential gauge winner Clint Patrick. Patrick is a plumber with DMT Mechanical Ltd. in Lethbridge, AB.

The flushometer was installed incorrectly with the critical level ignored. The waterline was repiped to raise the flushometer to the proper height.

Dylan Gerlack of EPCOR (WCSAWWA CCC member) presents Simon Jolly of Edmonton, AB, with a Zurn pressure differential gauge for his winning entry.

Eric Gagnier, chief plumbing inspector for la Régie du bâtiment du Québec (RBQ) presents an Apollo backflow prevention test kit to Nathalie Quevillon, training director at the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ).

This photo was taken at a morgue in a hospital. You can see the cross connections at the morgue’s table. There is also a sink in the same room with a disposer to grind body parts. There was a direct potable water connection to it.

This is an example of irrigation devices where the contractor used the hose bibs to blow out the water from the device and main before wintertime. This could cause some serious issues as compressors normally run anywhere from 100-120 psi and can push air back up the water main if it is not isolated from the city main. Other concerns include maintenance staff attaching a hose to water grass, and so on. We have no choice but to offer to remove the hose bib and cap the line (or preferably remove the tee altogether).
