< UPFRONT The 800-Pound Gorilla Russia recently announced an agenda to modernize its energy infrastructure, develop alternative energy sources, and to promote conservation and energy efficiency. The goal is to reduce the amount of energy output per unit of economic output by 40 per cent by 2020 (sptimes.ru/story/32235). The country currently uses “2.5 times more energy to produce a given amount of goods and services than the world average.” The reduction of residential heating consumption, which represents 70 per cent of domestic energy consumption in Russia, has been identified as key to meeting efficiency goals. In Canada, that figure is conservatively 60 per cent. This is in spite of huge investments of money, time, research and manpower to tackle the issue. Russia would do well to review Canadian initiatives – perhaps it will have better results. Efficiency and performance goals can be hindered by many things, not the least of which is the end user. But what is the 800-pound gorilla in the room? Well, there are certainly any number of options you could choose from, many of which the industry has little or no control over. On the other hand there are influences over which contractors do have control. Ian McTeer identifies some of them in his article A Whole New Venting World (p.16). In an ideal world we would have the opportunity to try different things, redo or undo what we want, when we want. Unfortunately, that is not often the case. Given the time of year though, we have taken some liberties. With a view to having a second chance and with a focus on efficiency, serviceability and other factors, John Siegenthaler shares (p.28) what he would do in his own HVAC/R “laboratory” – a mechanical room wish list so to speak. I wish our readers a safe and happy holiday season and look forward to sharing a prosperous 2011 with you. <>

A HEALTHY INTEREST In Energy Efficiency Energy management appears to be more important to healthcare leaders than to executives in other industry sectors. That is a key finding in a recent survey of facilities decision-makers around the world. The Johnson Controls Institute for Building Efficiency, the International Facility Management Association and the American Society for Healthcare Engineering conducted an online survey of decision-makers responsible for managing energy. The Energy Efficiency Indicator survey results included a separate analysis of responses from healthcare organizations. The survey looked at issues such as what organizations are doing in response to rising energy costs, what factors are driving efficiency improvements, what payback they
expect on projects, and what technologies and practices they are applying. Highlights of the survey include: • 59 per cent of healthcare organizations believe energy management is extremely or very important, compared to 52 per cent of respondents across all industries. • 66 per cent of healthcare respondents are paying more attention to energy efficiency than they were a year ago. • Cost savings is the biggest factor driving energy efficiency investments in healthcare; enhancing image and taking advantage of government or utility incentives are next. • Nearly 50 per cent of healthcare respondents cited energy efficiency in buildings as their top strategy for reducing greenhouse gas emissions. • The average maximum allowable payback period for energy efficiency investments in healthcare is 3.3 years, down from 4.2 years in 2008. • The top barriers to capturing potential energy savings are lack of internal capital and inability to identify projects with sufficient ROI.

Plumbing Fixture Requirements Delayed ments typical of residential drainline installations. However, when HETs are installed in industrial, commercial and institutional buildings, there are concerns about the drainline carry of a 4.8 litre flush volume. The BC Building Code’s HET requirement will be limited to residential buildings until further research on drainline transport issues becomes available. housing.gov.bc.ca/building/consultation/het/

British Columbia has pushed the highefficiency toilet (HET) and urinal (HEU) requirements in the BC Building Code to October 3, 2011. The one-year delay is expected to allow suppliers to reduce existing inventory and bring in new stock. At that time HETs or dualflush toilets will be required in new residential buildings or when renovations involving plumbing fixtures occur. Whenever urinals are installed, HEUs will be required. On average, high-efficiency toilets use at least 20 per cent less water than the 6-litre models that are currently required in B.C. According to recent research (cuwcc.org/resourcecenter/products/toilet-fixtures/drainline-studies.aspx), HETs have no difficulty meeting the waste transport require-

Making The Case For Efficiency Initiatives A report titled Improving Energy Efficiency for Alberta’s Industrial and Manufacturing Sectors clarifies current industrial energy use and practices. It also provides companies with essential information to make the business case for energy efficiency initiatives. Commissioned by the Government of Alberta, the report was created by CME Alberta in association with Stantec Consulting and Marbek. The study assessed the Alberta manufacturing industry, which was categorized into 10 manufacturing subsectors: food, pulp and paper, petroleum and coal products, chemicals and fertilizers, plastic and rubber products, primary metal, fabricated metal, machinery and transportation equipment, and other. The report identified technical best practices (TBP) and energy management best practices (MBP). The study found that most of the plants have implemented less than 42 per cent of applicable TBPs, with compressed-air systems having the highest rate of implementation. Overall, 75 per cent of facilities have implemented less than 37 per cent of the MBPs. Large plants have implemented close to 20 per cent more MBPs than small to medium-sized plants. productivityalberta.ca 8

CSA International, a division of the CSA Group, has received recognition by the Environmental Protection Agency (EPA) as a Certification Body under the enhanced ENERGY STAR program. Under this recognition, CSA International is able to qualify and verify that products meet ENERGY STAR requirements by testing them in its EPA recognized laboratories, by witness or supervised testing at manufacturers’ labs, or by verifying testing data from other EPA recognized independent third-party laboratories. As a Certification Body, CSA International will confirm a manufacturer’s compliance with ENERGY STAR requirements and upload the data required for EPA to authorize the use of the ENERGY STAR mark by a specific manufacturer for a specific product. To accommodate the increasing need from manufacturers for energy efficiency verification services, CSA will double its testing capacity across its laboratories. In November 2009, the EPA announced that the ENERGY STAR program was to require third-party testing of all eligible products starting in 2011. Previously, the program allowed companies to self-declare their compliance with ENERGY STAR requirements. The CSA Group recently announced “a new operational structure designed to accelerate CSA Group’s growth into expanding global markets while offering more efficient customer service.” Randy W. Luecke, president, CSA International and OnSpeX, is retiring from CSA Group. Glenn Tubrett assumes the role of vice president – Canada. Sue Dempsey continues her leadership and direction as vice president and general manager of OnSpeX. CSA Group North American will be led by Hélène Vaillancourt, executive vice president, engineering and science. csa.ca

Following a resounding public backlash against eco fees, Ontario’s Minister of Environment has confirmed that the government would be taking a different approach to dealing with municipal hazardous waste. According to the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), the new approach has not been clearly laid out. The government has eliminated the previous requirement under the Municipal Hazardous and Special Waste (MHSW) regulations that Extended Producer Responsibility Programs must be funded directly by the industries that produced the products named under the regulations. One of the hazardous wastes originally named in the regulations was mercury and mercury-containing thermostats. HRAI has sponsored a program known as Switch The Stat that covers the collection, shipment, and safe destruction of mercury thermostats for four years. Under the old regulations, which came into effect for mercury-containing devices and a range of other products on July 1, 2010, all costs related to the collection of thermo-

stats were to be borne by the manufacturers and importers whose brand has appeared on thermostats containing mercury at any time in the past. HRAI has been slowly bringing these stewards on board as funding partners in the program, which became the first Industry Stewardship Program (ISP) approved by governing body Waste Diversion Ontario (WDO). This approval meant that industry could manage its program independently (and at a lower cost to stakeholders) than the default alternative, which would have been a program under “Stewardship Ontario.” HRAI vice president Martin Luymes recently met with the Ontario Minister of Energy staff, to discuss the impact of the decision to eliminate the funding requirement on HRAI’s ISP. Ministry staff confirmed that the decision would let

industry stewardship programs like these “off the hook.” The Ministry was asked to provide some “consideration” to HRAI, such as an opportunity to advise on what the new legislation should look like and possibly some compensation for the financial burden experienced due to the rules imposed by Waste Diversion Ontario. Key funders of the Thermostat Recovery Program have agreed to continue funding the program on a slightly scaled down version. The committee recognized that replacement legislation is sure to come. They also understood that the HRAI program is now national in scope. It has been approved as a program to meet recently introduced waste diversion objectives in British Columbia and is awaiting similar approvals in Manitoba. Other provinces and territories are expected to introduce extended producer responsibility (EPR) legislation in the next year or so and it is hoped that HRAI’s program will satisfy the requirements in all provinces as they come into being.

Pioneering Heat And Power BIOMASS GASIFICATION System At UBC The University of British Columbia (UBC) is installing a biomass-fuelled combined heat and power (CHP) system at its Vancouver campus. The biomass gasification system will convert 25,000 tonnes (t) of wood residuals into clean synthetic gas annually. The locally sourced waste wood will come from landfill diversion, municipal and commercial pruning, land clearing, clean construction sites, sawmills and wood manufacturers. The “syngas” will power an internal combustion engine to produce two megawatts (MW) of clean electricity – enough to replace up to six per cent of the average energy demand on campus. Waste heat recovered from the engine will produce 9,000 pounds/hour of low-pressure steam for heating systems. Overall, the CHP system will reduce the university’s natural gas consumption by up to 12 per cent and greenhouse gas (GHG) emissions by 4,000 t per year. UBC is also collaborating with FPInnovations to house the CHP system in a new building constructed using cross-lami-
nated timber (CLT). CLT is a new building material made of solid wood that can be used as a low carbon, renewable alternative to steel frame construction. This building will be one of the first CLT buildings in North America and will demonstrate its market potential for the forest industry. The total cost of the UBC Bioenergy Research and Demonstration project is approximately $26 million. Construction is expected to be complete in late 2011. nexterra.ca/news/100215_QA.html

A Whole New
Venting World
Making the leap to sidewall venting using plastic pipe sounded so easy, but experienced HVAC contractors knew better. The everyday slide-out/slide-in simple residential retrofits are gone forever. BY Ian McTeer

TIP
t this writing, the winter of 2010/11 is fast approaching. Distributor and HVAC contractor warehouses are being quickly depleted of the last legal mid-efficiency gas furnaces stockpiled to beat the 90 per cent AFUE phase-in earlier this year. Just think, no more worries about sizing vent connectors, no more Table “C” DP (F+N) calculations, no more Annex C. Of course you know it cannot be that easy. Residential HVAC contractors will be quotDevelop a venting plan when ing some residential jobs at considerably higher quoting the job.

It has been over 25 years since I first “solvent welded” my first venting system together. I thought we learned then how things like vents with too many elbows, or piping sloped towards the outside wall, would cause service calls. I was wrong: I still see far too many of these installation errors today. A short section of vent pipe with no slope can accumulate enough water to cause the furnace pressure switch to open.

RULES A RESIDENTIAL HVAC CONTRACTOR MUST FOLLOW: • • •
•
•
•
The venting system must be designed and installed in accordance with the furnace manufacturer’s installer’s guide. The venting system must not be overlength for the material size selected and the number of elbows used. The manufacturer’s instructions are unequivocal here. The venting system must be properly supported; typically every three feet using metal pipe strap that is anchored to a solid construction member of the building. Hanging a venting system from duct work is not acceptable. The vent pipe must slope downhill toward the furnace typically ¼" per foot. That means a 20' long vent system must have the furnace end of the pipe 5" lower than the termination end. The outside vent terminal must be constructed properly with due consideration for the gas code and other things, such as accumulated snow level, adjacent buildings, human and vehicular traffic. The vent must be stress relieved – do not run 20' of horizontal pipe with only one 90º elbow in the system. Too much torque on the vent motor can cause vibration, water leaks and premature failure.
Consider using an approved termination kit available from many wholesalers. Termination kits must be installed exactly as shown; they cannot be snorkeled or extended beyond the original design.
codes. The trouble is this: it is often difficult to satisfy all the codes and instructions. Add to that the fact that some homeowners absolutely hate the look of whatever termination you have installed. I know several contractors who use terminal mock-ups to provide a potential customer with a heads-up on what the vent terminal will look like, but even then some customers are dissatisfied after the job is done. Janice Bradbeer, a Toronto Star editor, wrote an entire column about her furnace vent terminal (Toronto Star, January 31, 2009) calling the terminal an eyesore, among other things. What is a contractor to do? Certainly the sales person should plan out the best possible route for the installer after a complete consultation with the end user. Take photographs, even a video and bring them back to the office for the installation crew to see. If continued on page 20

instructions often insist the terminal be 12" above the highest anticipated snow level. According to Environment Canada’s accumulated data from 19712000 (Climate Normals), Ottawa can expect an average snow depth of 10" in January, Toronto 3", Edmonton 7.5", Winnipeg 7". Thus Ottawa area vents should terminate 22" above grade. That is going to be an ugly vent. And, the vent will have to be insulated – this is crucial. With that very exposed vent, condensate freezing in the base elbow is likely without effective insulation. An unremarkable U.S. vice president once quipped, “What this country needs is a good five-cent cigar.” I am sure there have always been more pressing worries for any country to consider, but borrowing on his theme I say, “What our industry needs is an easily installed, insulated, and decorative sidewall gas furnace vent termination, and a low price would be appreciated too.” Vent pipe manufacturers have neglected the need for practical terminations after the industry was forced to move to certified pipe. NO HEAT SERVICE CALLS
Again, inlet terminates in front of the vent. Inlet elbow should be turned 90 degrees. Use of screens may or may not be recommended (local experience dictates).
Horizontal plastic venting systems can put a lot of torque on the furnace draft inducer creating noise, vibration, and possible premature failure. By offsetting the vent
A service call generated by a pressure switch error must include an inspection of the vent terminal and the venting system. Is the vent terminal buried in snow, frozen solid, covered up by the inflatable swimming pool, full of stones/ toy cars/tennis balls/critters? The service tech should then look at the vent pipe to be sure the reverse slope is maintained for the ENTIRE length of the system. Have a look at the furnace fault code reporting system but do not make any adjustments or repairs until the vent termination and vent pipe system have been carefully inspected. Benjamin Franklin, the American politician and philosopher wrote in “Poor Richards Almanac” in 1758 that, “…for want of a nail the shoe was lost; for want of a shoe the horse was lost; and for want of a horse the rider was lost.” Ignoring seemingly small things has a way of escalating into large problems: for want of ¼" slope, the heating system was lost. Let’s not forget why the government moved our industry to 90 per cent AFUE; we must do something to reduce greenhouse gas (GHG) emissions. If you add up the wasted energy generated by the service vehicle to fix a problem that should not have occurred and add it to the energy budget of the furnace involved, the GHGs will be out of line for that furnace forever. Higher technology demands greater precision from all of us so we must do better to be sure an otherwise acceptable installation is not compromised by errors, large or small. <>

“Sprinter has the lowest cost of ownership in its segment.” - Vincentric (independent, automotive researcher)1 Of the many reasons why you should consider a Sprinter, the most notable is its lowest cost of ownership in its class. As a result of having been built to the quality and standards one would expect from a Mercedes-Benz, you’ll enjoy the longest average maintenance intervals along with amazing fuel efficiency. Its taller, wider doors open to reveal an impressive cargo area of up to 547 cubic feet with a 6.4-foot ceiling – and with its payload of up to 5,375 lbs, that means you can load over 100 sheets of drywall, or over 80 bags of concrete.

hen Benjamin Franklin came up with this little gem: “an ounce of prevention is worth a pound of cure” I am not sure what he was referring to when he coined the phrase, but I can imagine a great many examples in every sphere of life where it rings true. In the plumbing world alone there countless examples, but in the interests of meeting my deadline (barely), let me focus on just one, the simple backwater valve. A backwater valve is a device that can be installed in a main sewer line to prevent sewage from backing up into the basement. The valve automatically closes if sewage backs up from the main sewer, preventing the back up from flooding the basement. A properly installed backwater valve must be placed in the main drain just before it leaves the house, downstream of all other connections so that sewage backup will be stopped and not come out through other outlets in your basement, such as floor drains, toilets, showers and laundry tubs. There are several types of backwater valves but they are all basically check valves for the drain, allowing water and waste to flow one way but not the other. The main difference would be in whether they are normally closed, or normally open. A normally closed backwater valve is most like the swing check type valve you would see in many plumbing and heating piping applications. The more effective valve in a drainage system is the normally open type. A normally open backwater valve has a stop gate that only lifts and closes in the event of reversal of flow. The normally open valve is less prone to catching debris and clogging up, it can allow a drain cable to pass and be retrieved, and it allows the building drain and vent system to ventilate the municipal sewers. All of these benefits make the normally open type the best choice for a backwater valve. It is the ounce of cure for an all too common occurrence that can be so easily and prevented relatively inexpensively.

Anyone who has ever experienced a flooded basement due to a sewage back up knows all too well the destruction and mess that is left behind. I have been fortunate enough to have avoided this particular trial personally, but as a plumber I have seen my share of basement disasters. I was travelling recently in eastern Ontario with the leating specialist from our Cornwall branch, Kelly Cameron. We had spent the day visiting several projects that Kelly had been working on and it was just about time to go enjoy a nice dinner and perhaps one or two cold drinks, a nice reward after a long day's work. Before we could put this plan into action however, Kelly received a phone call from his panicked better half telling him their basement was flooding and he needed to get home pronto. Now I guess I had a choice, after all it was not my basement that was flooding. I could have gone on to dinner alone and left Kelly to the mess, or I could go with him and lend a helping hand. So off we went, and believe me, the fact that I had left my car at the branch and Kelly was my ride had nothing to do with my decision what so ever. I could have easily walked a few miles to get my car even if it did happen to be in the middle of the heaviest rainstorm since Noah sailed his ark, but I digress. When we arrived at Kelly’s house it was not pretty. The rain that had been falling all day long, the same rain that had nothing to do with my decision making, had everything to do with the lake that was now taking residence in the basement. At six inches and rising, it was already deep enough to have flooded out the burner in the gas water heater and the gas furnace was just inches away from suffering a similar fate. We dove in and rescued as many things as we could, stereo speakers, video game consoles – anything that was small enough to move was air lifted to higher ground, but continued on page 26 HPACMAG.COM

A Second Chance For 30 years my home has been a personal laboratory where I could test HVAC devices and techniques to my heart's content. BY JOHN SIEGENTHALER
O
ne of the fringe benefits of being in any trade is early exposure to many of the devices coming to into the market. If you are like me, you probably surmise how many of these devices would work in your own house. You probably form an opinion on them based on the following: • Do they make sense technically? • Are they built to last? • Are they serviceable? • Are they efficient? I know several comfort professionals with very unique combinations of heating hardware in their own homes and places of business. They have acquired this hardware and are running their own tests to see how well it performs before using it in their customers' buildings. I really respect this approach. It points to a self-responsibility for what they offer to their customers, as well as an open mind to all things new. It also demonstrates experience that understands how some products do not shine as brightly in the field as they do in advertisements and promotional materials.
A PERSONAL LABORATORY My wife Joyce and I built our house in 1980. It was a long process because we did much of the work ourselves. Anyone who has ever lived in a house as it was being constructed can tell you it makes for some challenging experiences. You get used to living with dust, rain tarps, temporary lighting and the smell of various adhesives and paint. You learn how to wash dishes in the bathroom sink, because it is the only source of running water. 28
HPAC | NOVember/DECEMber 2010
Joyce envisioned this house as a nest in which to raise children, decorate with lacy curtains and cook great meals. I saw it as my personal laboratory for experiments in home energy systems, including superinsulation, air-to-air heat recovery, wood burning, solar and wind energy harvesting and waste heat recovery. Being the gracious and supportive wife she is, Joyce indulged me through many years of such experiments. She would call me when there was a “funny noise” coming from the mechanical room and occasionally reminded me to write a manual on how the system operates in case we ever sold the house. That manual is still on the to-do list. Although our primary means of heating the house has changed several times over the last 30 years, the fundamental objectives of energy conservation, gathering “free” energy and using hydronic heat delivery have always been part of the mix. Our original means of heating the home in the snowy, 8,000 degree day climate of upstate New York, included three subsystems: • Passive solar gain through 395 sq. ft. of southfacing windows. • 112 sq. ft. of flat plate solar collectors. • An airtight wood stove. The latter was for “supplemental” heat, just in case the sun did not shine as brightly as expected after all of the pricey solar hardware was installed. When we started building our home I worked for a company named Revere Solar & Architectural Products. This company was a division of Revere Copper and Brass, and manufactured flat plate solar collectors. Our house obvihpacmag.com

ously had to include some of those collectors. I settled on six, 35-inch by 77-inch collectors with specially sloped internal headers, as shown in Figure 1. The collectors face directly south and are sloped 60º from the horizontal. The solar system was designed as a closed-loop drainback design. I felt this approach held many advantages at the time and I still believe it is the best approach for solar combisystems that provide space heating and domestic hot water. This system has been through many winter nights with temperatures of -25F, and the drainback operation has never failed me. Those 30-year-old collectors are still up on the roof and working, albeit at a somewhat decreased efficiency. We suspended two 60-foot coils of 1/2" copper tubing, piped in parallel, from the access plate at the top of the tank. They preheat domestic water whenever hot water is hpacmag.com
drawn from a fixture. Over the years I have been very pleased with the performance of this homemade heat exchanger. Although it is possible to access it by opening the top of the tank, I have never had to do so and do not plan to as long everything keeps working as it has. When the tank was warm, space heating is provided by circulating water through 3/8" soft-temper copper tubing embedded in a thin masonry layer installed over the standard subfloor. PEX tubing was not available in North America at the time. Interestingly, Revere Copper and Brass was one of the industry leaders in using copper tubing for radiant panel heating back in the 1940s and 1950s. So I designed the system using some of the older technical manuals they produced. Everything was soldered together and still is. We installed a manually adjusted mixing valve in case the water in the tank was too warm to go directly to the floor circuits.
MOVING ALONG By the late-1980s we were ready to add an automatic heat source to the system so we did not have to kindle up the wood stove every cloudy winter morning. At the time, our local utility was offering rebates to help “seed” the market for ground source heat pump systems. We took advantage of this program and in 1987 I installed a small (18,000 Btuh rated) water-towater ground source heat pump. The heat pump performed well, but after a few more years we decided it was time to add some heat in the garage. The heat pump just did not have the output to handle this additional load, so we moved it and installed an oil-fired, castiron boiler. The heat pump still remains, but it is now used only for chilled water cooling, a task it handles very well. Figure 2 shows how our heating/cooling system was last modified about nine years ago. Injection mixing and primary/secondary piping were the cutting edge technologies at that time, so naturally they had to be worked into the mix. You will notice that there is an extra set of closely spaced tees on the primary loop waiting for some future experiments. continued on page 30 NOVEmber/DECEMber 2010 | HPAC

walls with a nominal R-32 rating. Today I would use thinner wall framing with spray foam insulation to achieve an R-40 rating along with R-60 rated ceilings. I would also get the most energy efficient windows that I could afford, probably with an R-value up around 5. I suspect the design heat loss of a similar size (around 2,700 sq. ft.) new house would come in somewhere around 20,000 Btuh. A heat recovery ventilation system would be used to maintain good indoor air quality. 2. I would face the long side of the house between 15 and 30 degrees east of true south. The southerly side of the house would have windows totaling about eight per cent of the home’s total floor area. This would provide passive solar gains in the morning, while at the same time minimizing heat gain from afternoon sun in the summer. Properly sized overhangs would also be used to minimize summer heat gain. Limiting the southerly window area to eight per cent recognizes that upstate New York is not a
very sunny place in winter. We originally installed south facing windows that totaled to 15 per cent of the home’s floor area. When the sun was out the temperature in the house would quickly climb into the 80s, even on very cold days. By the next morning the house has dropped into the upper 50s due to the heat loss through all that glass. The lesson learned: There is such a thing as too much passive solar gain. Over the years we have reduced the south facing window area and installed higher quality glazing than what was available in 1980. 3. To keep things comfortable when the sun was not shining I would install low thermal mass panel radiators. Each room would have its own panel radiator equipped with a thermostatic radiator valve. The latter would allow each room to adjust to varying heat gains or comfort settings. The panel radiators would all be supplied by a simple home run distribution system using ½" PEX-AL-PEX and a single manifold station. A single ECM-based pressure regulated circulator with a peak electrical power demand of around 40 watts would power the entire distribution system. 5. The heat source would be a “tank type” device containing 80-119 gallons of water for high thermal mass. This device would be very well insulated (minimum of three-inches of urethane foam insulation on all surfaces). It would also have very low pressure drop characteristics. The circulator input power required to move water through this heat source would only be one or two watts. There would be no need of a separate boiler circulator. The burner and internal heat exchanger would be modulating and compatible with condensing mode operation. The water temperature within the heat source would be controlled based on outdoor reset. The high thermal mass of the heat source would nicely buffer the highly zoned distribution system to avoid short cycles of the burner. 6. The tank type heat source would also serve as storage for a modest array of flat plate solar collectors (probably 100 to 130 square feet of collector area facing parallel with the building (15 to 30 degrees east of true south), and sloped at 60 degrees (latitude +15 degrees). The collector array would be designed for drainback freeze protection. No antifreeze would be needed. The drainback air space at the top of the tank would also serve as the system’s expansion tank. continued on page 34

7. Domestic hot water would be produced “instantaneously” using a stainless steel brazed plate heat exchanger supplied by a very small, (nominal 10 watt) circulator controlled by a domestic hot water flow switch. This small circulator would move hot water from the top of the well-stratified storage tank through the heat exchanger whenever a hot water faucet opened. A similar strategy has been used in Europe for instantaneous domestic water heating for years. If this heat exchanger ever failed it could be serviced or replaced without having to open or replace the storage tank. I see this as a major advantage in comparison to what has to happen when a coil heat exchanger inside a large storage tank fails. 8. For cooling I would probably just get a couple of good quality window air conditioners. Where I live, cooling is only needed on four to eight mid-summer days. It is hard for me to justify a central cooling system given this minimal usage.

The schematic in Figure 3 is a close representation of these heating system concepts put together. I suspect that my preferences as to what constitutes an optimal heating system for my own house will change in coming years. This will likely be the result of new products and more learning on my part. It is part of what makes this field so interesting and exciting – it is definitely about the journey rather than the destination. <>

< SUSTAINABILITY
Synergy Spells Success Interaction of sustainable technologies proves to be a recipe for savings at a Quebec microbrewery. BY LUc Boily
C
hoosing to implement energy efficient technologies and numerous efficiency measures has reduced Les Brasseurs du Nord's electricity consumption by 42 per cent over the last four years. Adopting sustainable technologies earned the microbrewery the grand prize in Hydro-Québec’s 2009 Energy Wise Competition of Excellence. Located in Blainville, QC, it produces 8,000 hectolitres annually, or about one per cent of the beer produced in the province. Despite expanding its facility and increasing production, the 3,700-m2 facility now uses less energy. “When we made the decision to expand, we put environmental concerns on the top of our list. As far as we are concerned, this priority applies in every instance: eco-friendly packaging, energy efficiency and water conservation,” said Laura Urtnowski, president of the company. The $5-million project, which included a $500,000 investment in sustainable technologies, was carried out between 2006 and 2009. According to Urtnowski, the key aspect of the plan, which integrates 10 energy efficiency measures, has been the

synergy between those measures. Serge Bastrash, president of Klimfax, the Longueuil-based mechanical firm responsible for the project's green building aspects, also emphasized that the bottom line of such a project is a general merging: “The main aspect to keep in mind when you begin an energy saving project such as Les Brasseurs du Nord, is to get the energy from the most practical source, in the most efficient way. That is why it’s so critical to have an overall picture of the project and to know each sustainable technology very well."
Green Highlights: • Installation of a solar wall to preheat fresh air entering the building. • Flow control of the fresh air (variable volume of 12,000 CFM) with a processor measuring the barometric pressure of the air in the plant. • Specific activation of the evacuation ducts only when needed via sensors detecting the amount of CO2 present in the plant. • Installation of a non-traditional geothermal system, which utilizes one pump. Reduced refrigeration requirements by 50 tons.
Ventilating unit. hpacmag.com
The software program used by Les Brasseurs du Nord ensures the synergy between all systems. It also ensures a better processing control by recording temperature, density and pH data. This advanced tool prioritizes the demand for cold according to fermentation needs and cooling capability of the compressors.
• Automatic control of the well pump rate with a system monitoring the demand for cold. • Return of the cooling water in the same underground well. • 100 per cent recovery of the heat generated by the
compressors, for manufacturing process and for heating the building. • Reduction of 60 per cent of the energy generated for refrigerant circulation, by replacing 10 fixed-speed circulation pumps with only one automated, variablespeed pump. • Saving up to 30 per cent of the demand for cold by adding modulating valves at the fermentation vats, also preventing overcooling. • Computer control of all HVAC components as well as all refrigerating processes. “We have reduced our greenhouse gas significantly by relying on automation, recovering energy, improving efficiency of our gas boilers, reducing the number of compressors needed for refrigeration, and decreasing the amount of refrigerant used in our possesses,” said Urtnowski. Bastrash, who estimates that the project should provide a return on investment in only a few years, reported that Hydro-Quebec plans to re-examine its financial contribution policy to such projects, given their exceptional return. <>

WHAT THE CONTRACTORS SAY BY BILL ROEBUCK
T
odayâ&#x20AC;&#x2122;s market is teaming with service vehicle options and it pays to do your homework (see sidebar) before you invest in one or more vehicles for your business. Some contractors tend to stick with one particular brand of truck, while others like to mix them up, depending on their specific needs. One example is Kolostat Inc. of Montreal, a multi-faceted mechanical contracting firm specializing in bid and spec, design-build, and HVAC preventive maintenance and service. It has both a flexible yet consistent approach to its fleet, which totals 24 vehicles and includes a mix of GMC, Chevrolet and Ford products. The company, which was started in 1927, has roughly 115 employees today, along with a permanent facility in Toronto. The company uses a mix of leased vans and pickups, with the construction division using a pair of Ford F-350 pickups and one F-250 model. The most common models in the fleet are its 18 GMC Savana cargo vans used by service technicians. These are supplemented by a pair of Chevrolet Uplander minivans that are used by technicians in the controls division. The vehicles range from 2003 to 2007 models. There is nothing fancy in them, unless you consider air conditioning to be a perk. In addition to the vans and pickups, the fleet also includes a Chevrolet Express cutaway van used for deliver-
ing supplies, as well as a large GMC C7500 truck used by the firm's construction crew. Tracking all of this equipment has been made easier for the company thanks to its arrangement with the leasing company. "They have a system we use and they manage everything for us," says Peter Murray, Kolostat's chief financial officer, "We benefit from cost-avoidance with them, and have a good overview of all of our fleet costs." The software program tallies up fuel and maintenance expenses and can flag a vehicle or a driver that is out of the norm. "Sometimes it can be the driver that's the problem, if they're too heavy on the pedal, for example," says Murray. The service vans typically see 20,000-30,000 km per year, and are run for about six years to around 140,000 km. Kolostat leases its trucks for 60 months, buys them at the end of the lease, uses them for another year and then sells them privately. "We'll be retiring a couple of the older cargo vans this year, and adding three new ones," says Murray. The firm uses a local upfitter to install Canadian-made shelves, drawers, ladder racks, plan tubes and such. "We used to do it ourselves, but this way is much better," says Murray. The equipment is usually moved into the new vehicles when the old models are replaced. continued on page 42

"We are selling savings through the red
uction of energy costs, and being green, durable and environmentally
friendly. So it would make sense to have our fleet made up of hybrid vehicles." One frustration Murray has is the long lead times for the delivery of replacement trucks, in part because they are ordered in a silver colour. "We need to make up our minds quite a bit ahead of time -- several months -- so that's an issue." Also, the company also would like to install GPS tracking systems into the vehicles to make it easier to track mileage, but so far has felt resistance from its unionized staff. In support of the company's green initiatives, Murray wishes he could find a hybrid product at a reasonable price. "We are selling savings through the reduction of energy costs, and being green, durable and environmentally friendly. So it would make sense to have our fleet made up of hybrid vehicles." At Hawk Custom Sheet Metal Ltd. in Red Deer, AB, president Mel Steer is completely loyal to the General Motors brand. He only uses pickup trucks in his fleet of about a dozen GMC Sierras, which range from 1996 to 2009 models. Most of the pickups are half-ton 1500 Series units, with one three-quarter-ton and two one-ton versions in the mix, the latter for hauling heavy materials to and from jobsites. Currently Hawk has six crews on the road, with between one and three technicians in each. Hawk does not use upfitters, preferring to build its own racks and toolboxes to fit the pickups. Steer says he tracks the fleet's costs manually, keeping records in a folder for each truck. "We run the trucks till they start to cost us too much," he says. That's typically between 250,000 and 300,000 km. "We get our money out of them!" That “running them until they get too expensive” philosophy is shared by Keith Plumbing Heating Co. Ltd. in North Vancouver, BC. "We have 20 one-ton service trucks, a mix of GMC Savana 3500 and Chevrolet Express 3500 cargo vans," says Herb Adams, service manager for the company's service division. In addition, the comp-any 42
HPAC | NOVember/DECEMber 2010
has a construction group that is managed separately and has its own vehicles, including a couple of four-wheel drive Toyota Tundra pickups used by its Whitehorse, YT, branch. Keith Plumbing is mostly loyal to the GMC model line, although Adams notes that there is a lone Ford F150 pickup truck that was purchased a few years ago. "They last us for a long time, typically eight to 10 years. Most of the guys like Chevys and GMs. Our techs find them to be comfy and roomy. They're very durable. We've had no major problems." Each truck has its own fuel card, but other expenses are tracked with pen and paper. Maintenance work is done at a local garage, and Adams keeps track of the invoices. Upfitting of shelves and racking is handled locally as well. The current fleet ranges from 2000 through to 2010 models. The company has been replacing two or three vans a year over the past couple of years -- although some have been added to the fleet as the company grows. Twelve years ago, when Adams joined the firm, there were just eight trucks being used. Adams also faces the challenge of a lengthy lead time when ordering new models. "It takes three to five months," he says. But he admits that is because the trucks are ordered in a special colour -- school-bus yellow. "The owner has been painting the trucks yellow and red since the 1950s and won't change now," says Adams. Keith Plumbing's name appears on a bright red side panel that is painted on locally. "We could walk across the street to a dealer and get a white one," notes Adams. "In fact, we once tried painting a white van yellow but it didn't work out for us. To get what we want, they have to be factory-ordered.” <> Bill Roebuck is a long-standing member of the Automobile Journalists Association of Canada (AJAC), and has been writing the annual Service Vehicle Report for HPAC magazine since 1999. hpacmag.com

Sticky Product… Stickier Problems

The product name is a misnomer and many issues with performance and indoor air quality can be attributed to it, as was the case in this fragrant mystery.
e cannot use the brand name but it is known as ‘the handyman's secret weapon,’ also known as “fabric-based tape with rubber adhesive” ala Lawrence Berkeley National Laboratory (see below), or “a polyethylene, reinforced, multi-purpose pressure sensitive tape with a soft and semi-flexible shell and pressure sensitive adhesive.” It made guys such as Red Green famous, earning the right to add ‘master taper’ to their sparkling resume. But as everyone knows, the last thing you want to use on ducts is the handyman's secret weapon. This was validated a few years ago by studies conducted at Lawrence Berkeley National Laboratory (LBNL) Environmental Energy Technologies Division where researchers discovered that the stuff becomes brittle and fails. You did not need a Ph.D. to figure this out. Any competent sheet metal contractor would tell you the same thing. In fact, if “Do Not Use This Tape On Ducts” was printed on every roll sold at do-it-yourself (DIY) stores we would prevent a significant number of duct leakage problems created by part-time tinsmiths. It would also have prevented an IAQ call that started this way, “Why does our entire house smell like Dipalmitoylethyl Hydroxyethylmonium Methosulfate?” Ok,they did not say “Dipalmitoylethyl Hydroxyethylmonium Methosulfate” but they did use the name of a well-known brand of laundry conditioning product. The odorous aroma found a way to spread its bouquet into every nook and cranny of the house. The owners could not figure out how it was happening.
IAQ >
After a few questions such as: “Did your kids play hide and seek with the stuff at their last sleep over?” to “Have you checked your clothes in the closets because the product is supposed to stop static cling but it sticks to your clothes (go figure)?” to “Have you checked to see if there is any air coming out your dryer exhaust hood?” The owner had a eureka moment at this point and came to the same conclusion I had arrived at earlier. Somewhere between the dryer and hood there was a broken dryer venting connection. It was leaking into an equally leaky return air plenum, where it was subsequently distributed through the heating ducts. We needed a video probe for this one. After a call to my buddy Doug Muncaster, who has all the toys, we set out to locate the cracked culprit (see Figure 1). Like all failures, it was in the worst possible location and was accessible only by ripping down portions of a finished ceiling (see Figure 2). The repairs have since been done (braced and clamped) and the video cam is off doing what it does best on some
other trouble shooting call but the headaches this once sticky product creates for IAQ and energy efficiency are long term. They often cannot be resolved without major destruction and then restoration work. To this I say, the handyman's secret weapon is cool stuff but it is in need of a name change and should not be sold to DIY’r tinsmiths, unless of course the DIY’r is a master taper with a hit television program. <> Robert Bean, R.E.T., P.L.(Eng.), is registered practitioner in building construction engineering technology (ASET) and a professional licensee in mechanical engineering (APEGGA).

Strengthen Your Business With More and more people are using Twitter, Facebook and LinkedIn to chat with friends or share pictures of their children. But have you thought about how to harness the power of these social media tools for your small business? BY HOWARD GROSFIELD
S
ites such as Twitter, Facebook and LinkedIn serve many purposes from a personal perspective, but social media also provides user-friendly tools to help run and expand your small business. Whether you need to hire a new employee, show off your latest products, attract new customers or get some advice, a website exists that can fill the need at little to no cost. Facebook, Twitter and LinkedIn each have their own merits and you do not have to become an expert in each overnight, nor do you need to have technical or design skills. That said, a full social media strategy takes time to both develop and execute and as we know, time is often in short supply for small business owners. Spending time browsing what your competitors are doing or chatting with peers in other cities will help you understand the scope of what is possible and whether a social media presence is a must-have for your business. Here are a few simple ideas of things that you can use to test the waters, without investing a substantial amount of time.
TRY THIS
According to recent statistics, about half the Canadian population has a Facebook (facebook.com) account. That is a huge potential audience to showcase your brand. Small businesses use their Facebook pages to highlight products There are some things you can do immediately. Search Facebook for groups and pages dedicated to small business topics and for communities relevant to your business. Many small business publications and organizations have accounts allowing you to find and discuss articles on everything from new standards and regulations to common employment issues.

A PICTURE IS WORTH… Check out Flickr (flickr.com), a photo-sharing site that can be an invaluable tool for sharing photos of your products and services with potential customers. The site allows people to upload photographs from their computers or telephones and then edit, add captions and organize them into folders.

SHOWCASE YOUR BRAND
and services, provide a space for discussion and feedback and to offer product coupons. Facebook has numerous applications to help businesses grow. As a start, take some time to browse through the Facebook ads, marketplace and business card tools. Canadians use Facebook to make connections with others who share their interests – some silly and some very targeted. There are fan groups for people interested in home improvements and those who want to compare the merits of various trade shows – essentially something for everyone and something for every market. And while Facebook is a great tool for reaching your customers, developing your own page will require investing some of your time.
Take before and after photographs of challenging projects and solutions. Or snap new products on the market that you have installed or endorse and load them onto Flickr. Then e-mail a link to your album to existing, new and potential customers.
Photos may be organized by category and tagged with descriptors, such as plumbing solutions. This allows other users to find your photos in a search. Like Facebook, Flickr allows you to join groups, share your photos with as wide an audience as you desire and comment on others’ photos. continued on page 62 NOVember/DECEMber 2010 | HPAC

CONNECT TO CUSTOMERS
TRY THIS
Building a following on Twitter takes time, so initially your tweets may not be seen by large groups of people. Conversely, building a group for you to follow can be done quickly by searching for competitors, suppliers and trade organizations. Go back through recent postings, watching for industry trends and innovations and to see how companies are using Twitter to build their business.
Many small businesses use Twitter as a means to connect to their customers, providing an opportunity for open dialogue and to build loyal relationships. Many retailers and service providers use Twitter to advertise upcoming promotions, for example offering a 20 per cent discount to your Twitter fans for a particular week on items such as regular maintenance, duct cleanings or product upgrades.
NETWORKING TOOL LinkedIn (linkedin.com) is primarily a professional networking tool, with a much narrower scope than Facebook. While recent research* found that Canadian small business owners are still relying on newspaper advertisements and word of mouth to find job candidates, LinkedIn can widen the
scope of your search effortlessly and at little to no cost. Members generally post their work experience, educational history and other work-relevant details, allowing themselves to be searched by other members. Is there someone you would like to be introduced to, who could be a key contact for your small business – perhaps a supplier that you would like to partner with? Chances are you can look them up on LinkedIn and find out more about them. You will even see if an existing contact also knows that individual and can make an introduction.
TRY THIS
Twitter (twitter.com) is probably the simplest of all the major social media tools. Twitter is a micro-blogging site, where users can send out messages of up to 140 characters as often or as seldom as they want. Some users see Twitter as a venue for their daily stream of consciousness, but others keep their messages – or “tweets” – limited to a particular interest.

While posting a job advertisement does incur a fee, the reach of your advertisement is geographically far greater than in a newspaper. And searching the database for a keyword phrase such as “heating specialist” could net you a potential employee or a future supplier. For many who are not familiar with the tools, entering the social media world may seem like a daunting task. But these tools require low technological expertise and often no budget. It is worth setting aside a few hours to explore the possibilities. Once you have taken some time to familiarize yourself with Facebook, Twitter and LinkedIn, you will have a better sense of whether it is the right time for you to develop a social media strategy as part of your overall business plan. <> Howard Grosfield is the vice president and general manager of small business services for American Express Canada and International. *American Express Small Business Monitor.
