Feds take early exit on eco-program Natural Resources Minister Joe Oliver unexpectedly closed the ecoEnergy Retrofit - Homes program to new registrants on Sunday, January 29, more than two months before its official end date, scheduled for March 31, 2012. In doing so, the government has limited participation to the approximately 250,000 homeowners who had registered on or before that date.

Along with the termination notice, the government adjusted the program somewhat, extending the post-retrofit evaluation and grant application deadline to June 30, 2012, with the caveat that all retrofit renovations must still be completed by March 31, 2012.

“With the Harper government focused on creating jobs and securing Canada's energy future, we are surprised that Minister Oliver closed such a successful program early,” says Jeff Murdock, vice-president of Building Insight Technologies, a Vancouver-based energy audit company and Save ecoEnergy Coalition supporter. “We are shocked that the federal government is cutting back its investment in jobcreating and energy saving retrofits at a time of global economic, environmental and energy uncertainty.”

According to Murdock’s company, it is estimated that the federal government will end up investing less than half of the $400 million commitment made to the program in the 2011 budget, but the lack of exhaustion of the funding is not the problem, says Warren Heeley, president of HRAI. The bigger concern, he says, comes from the government failing to make long-term commitments to such programs.

“Jumping into and out of incentives is wreaking havoc on our industry, and others,” he explains, adding that temporary grant programs create bubbles in the marketplace with drops in sales before and after incentive programs as the marketplace reacts to real or anticipated grant monies.

Along with its partners in the Save ecoEnergy Coalition, HRAI is encouraging the federal government to extend the ecoEnergy Retrofit program for an additional three years as part of the Coalition's fivepart Home Energy Action Plan. saveecoenergy.ca

Efficiency targets raised The 2012 edition of the R-2000 building standard was unveiled in February. The new standard includes measures to reduce water consumption and improve insulation and ventilation. Homes built to this standard will be 50 per cent more energy-efficient than homes built to the 2005 R2000 standard. According to a spokesperson from Natural Resources Canada, the new edition of the standard now includes Energy Star air conditioning equipment, rather than the EER and SEER ratings of cooling equipment. Water conservation requirements have also been adjusted to include 4.8 litre per flush toilets, 2.0 gpm showers and 1.5 gpm lavatory faucets. nrcan.gc.ca

Refrigerated Rink of Dreams opens The city of Ottawa unveiled its new refrigerated outdoor ice rink just in time for the NHL All-Star Game in January. The 12,500 sq. ft. rink, funded primarily by the Ottawa Senators Foundation, will be able to provide a reliable ice surface in temperatures as high as 10˚C. The artificial ice surface, which is three-quarters the size of an NHL rink, took four months to build. It will be open from November to March.

Barba honoured with Carlson-Holohan Award

Robert Bean (left) presents John Barba with the Carlson-Holohan Award.

Taco’s John Barba, the well-known hydronics training expert and occasional contributor to Mechanical Business, was awarded the Carlson-Holohan Industry Award of Excellence during the AHR Expo in Chicago in January. The award, which was last presented to Ken Webster of Viessmann, is given out every second year to an individual who has made significant contributions to the hydronics industry. It is named after the late Gil Carlson, a legendary instructor from Bell & Gossett’s Little Red Schoolhouse. taco-hvac.com

U.S. makes drastic R-22 cut American HVAC/R contractors are bracing themselves for increased R-22 prices this year. In January, the U.S. Environmental Protection Agency (EPA) issued a proposed rule that would significantly reduce the allowances for U.S. consumption and production of Hydrochlorofluorocarbon-22 (R-22). Refrigerant Supplier Hudson Technologies, Inc., reports that the EPA has issued “No Action Assurance” letters to importers and producers of R-22 reducing the amount that can be manufactured and/or imported in 2012 by approximately 45 per cent from 2011 allowances. Until the final rule governing R-22 allowances is announced, the EPA’s No Action Assurance limits the production and/or importation in 2012 to the maximum reductions in the proposed rule. As a result, contractors south of the border are already noticing significant increases in the price of R-22.

Will the changes affect the Canadian marketplace?

That’s yet to be seen, but Canada did import more than 1 million pounds of reclaimed refrigerant last year, and with the demand for that volume ramping up in the U.S., there could be reduced amounts available to Canadian contractors, and their customers. “That pool of reclaimed refrigerant will be needed in the domestic market in the U.S.,” explained HRAI president Warren Heeley during a recent interview. “It is likely that there will be less reclaim available for shipment into Canada.”

Recycling program hits 10-year milestone Royal Building Products is working to change the perception of PVC, which some may not view as a sustainable, or green, building material, and it has been doing so for 10 years now. “Royal is committed to sustainable manufacturing, and that includes recycling PVC scrap,” explains Mark Orcutt, executive vice-president with the company. “We have regrind machines set up in each of our facilities throughout North America.

We recycle 100 per cent of our scrap produced internally, and the recycled PVC is then shared throughout our organization and incorporated into new building products.” This means that scrap from the Window and Door division or Siding division can be sent to the company’s pipe business, which can use all types of recycled PVC. “By recycling PVC pipe, we now have a sustainable product that offers cradle-to-cradle environmental and energy-saving benefits,” said Lorne Smyth, vice-president, business development and marketing, at Royal’s Pipe & Fittings Solutions.

ASHRAE rebrands The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is updating its brand, a move the organization says reflects its progression within the building industry.

“The new ASHRAE brand supports our focus on improving engineering standards and our market position as a community of engineers and related professionals united by knowledge, mission and a code of ethics to design, construct and operate better places for people to live, work and play,” stated ASHRAE president Ronald Jarnagin. The changes, which include a new logo and tagline, and a redesigned website, were announced at the society’s 2012 conference in Chicago in January. ashrae.org

Energy Star for gas furnaces returns

Plumbing certification standardized

As of February 1, 2012, Canada reintroduced Energy Star specifications for gas-fired forced air furnaces. To qualify for Energy Star status, a furnace must be thirdparty certified as meeting Version 3.0 or 4.0 requirements. Effective the same date, the new Version 3.0 Specification now requires a minimum 95 per cent AFUE and a two per cent fan efficiency.

The executive committee of the Plumbing Officials’ Association of British Columbia has signed a memorandum of understanding allowing the Building Officials’ Association of British Columbia to administer certification examinations using the International Code Council certification process. The executive committees of both associations are working to design a plumbing officials’ certification system that could potentially be used for all of Canada, explained BOABC executive director Richard Bushey.

Manitoba to ban coal Manitoba’s NDP government plans to ban the use of coal for space and water heating effective January 1, 2014, but rural residents have expressed concern that the province might be moving too fast. Natural gas is unavailable in many rural areas, and a lot of farmers use coal to heat their barns and workshops.

The ban goes hand-in-hand with the province’s new biomass energy support program, which will provide financial support to users and processors of high-quality, renewable biomass for use in combustion heating systems.

Stainless steel down-ďŹ red Fire Tube design Nine models from 60,000 to 399,000 BTU/Hr Full modulation up to 5:1 turndown Advanced Sola Controller and Interface 96% AFUE efďŹ ciency

@EEFM8K@FE 8J JFC@; 8J JK<<C Down-fired Fire Tube The Trinity Fire Tube (TFT) heat exchanger is ASME certified and uses an innovative down-fired concept. The tubes have a dimpled design to optimize heat transfer, which increases energy efficiency. The Fire Tubes provide generous space for flue gas to pass, and significantly reduce the need for cleaning due to the vertical configuration and self-cleaning operation when in condensation mode.

Stainless steel design The wet leg combustion chamber enables up to 99% combustion efficiency. The ASME certified heat exchanger is constructed using 439 Stainless Steel, making it extremely resistant to corrosion. The Fire Tube design allows water to flow freely around the heating surfaces of the boiler, which significantly reduces pressure drop.

Efficiencies & performance The TFT provides AFUE efficiencies up to 96%. NTI was the first to develop the totally-sealed combustion system, whereby air is not drawn from the cabinet.

Q A

It was actually a summer job. I was in between school sessions, and I went down to Manpower. There was someone there who saw my application and said there was an opportunity at Emco, at the factory in the stores room. At the time we were in a recession and job prospects were not that good, so I expressed a want to carry on with Emco once I was done school, perhaps in a sales capacity. So I started with Emco Supply in Windsor.

How did you end up starting Morden National Sales?

I was in a national position with Delta Commercial Faucet, and was approached by ECR about a position as corporate director of sales for ECR in Canada. They were just starting out in Canada, having just bought Olsen. I did that for almost 10 years. Then they shut the plant down, and we started

HIGH PERFORMANCE HVAC

B y Go r d C o o ke Gord Cooke is a professional engineer who has spent 20 years helping builders and HVAC contractors implement innovative technologies into high-performance homes. He has particular expertise in IAQ and air flow management in houses, and can be contacted at gcooke@airsolutions.ca.

Redefining CAPACITY requirements or more than 20 years I have been wondering and asking why, when doing a heat loss or heat gain calculation for a house, designers have been directed not to consider or include the performance of a heat recovery ventilation system.

Similarly it always seemed a bit inadequate to try and describe the likely air tightness of a house with some simple subjective characteristics such as “average” or “very tight”, especially when the air leakage component of the final result might be as much as 30 or 40 per cent of the total. The answer is, of course, it was the best we could do with the information available at the time.

Well, I am pleased to report that the new CAN/CSA F280 Standard Determining the Required Capacity of Residential Space Heating and Cooling Appliances is now here. It will replace the 1990 edition, and I think all readers will appreciate that there have been a lot of changes in housing technology over the past 22 years that can now be more accurately reflected in this new standard.

Let’s have a look at some of the important features of the new standard, and the impact it will have on the sizing of heating and cooling equipment for Canadian homes.

F

Sizing limit REMOVED One interesting and hotly debated aspect of the new standard is the removal of the clause in the existing standard stating, “Heating system capacity shall not exceed the total building heat loss by more than 40 per cent.”

Notwithstanding the concern that inexperienced designers and contractors may feel compelled to add unneeded capacity without this restriction in place, it was felt that greater flexibility in system design was needed to respond to the reality of new homes and the expectations of homeowners.

For example, consider a very efficient new home with large areas of glazing on the east and west orientation of the building. A designer may wish to install two HVAC systems – one serving the east side, one serving the west side – to react to the intermittent losses and gains from those windows.

Combined, the capacity of the two systems might exceed the 140 per cent over-sizing limit. And yet, at any point in time, only one system may be operating to ensure the proper comfort levels in all parts of the home.

It is expected that the new HRAI Digest will provide direction to designers and contractors to ensure appropriate sizing decisions are made.

ACCURATE AND REPEATABLE The bottom line of the new standard is that it will provide HVAC designers and contractors with a more accurate and repeatable equipment sizing guide. It will take some getting used to, of course, as contractors recalibrate their long-standing rules of thumb for sizing.

For example, consider the results for a typical new two-storey, 2,450 sq. ft. home with a winter design temperature of -20°C and a summer design temperature of 31°C. Assuming that this new house is an Energy Star qualified home (with a specific air tightness target) and employing a heat recovery ventilator, here’s how the numbers stack up: Total Heat Loss (BTUH)

Air leakage component of Heat Loss (BTUH)

Total Heat Gain (BTUH)

Current CSA F280 New CSA F280 Of course, this is just a quick example, without listing all the parameters of the house, but are you ready to consider a 40,000 BTUH furnace for a 2,450 sq. ft. home?

The air leakage component has been shown specifically to show that the single biggest change (at least for a new home) in the new standard is the way natural air leakage is handled.

More changes to come

LEAKAGE VENTILATION Undoubtedly, the biggest change in the new heat loss/gain calculation is the way air leakage and ventilation is handled. There are four important features to the new standard in this regard:

With the standard being published this month, there is still work to do. The Heating Refrigeration Air Conditioning Institute of Canada (HRAI) initiated the development of the new standard and now will be revising the HRAI Digest to incorporate the features of the standard.

Housing authorities and building code officials will have to formally adopt the new standard to enable designers and contractors to use it in new housing applications.

Software programs, such as RightSuite HVAC Automated Design software, will have to be updated.

These features will be incorporated into a spreadsheet embedded in the new standard. The algorithms in the spreadsheet are based on the Alberta Infiltration Model (AIM-2), which was first used in the HOT2000 program.

A second similar embedded spreadsheet approach will be used to update the calculations of heat loss from the foundation of a home. This new foundation approach accepts a much greater range of basement configurations and insulation methods now commonly used in new and existing homes.

Designers will also now have a much wider choice of window types to select from to reflect the significant change in window technologies now available. Specifically, the U factors and solar heat gain coefficients reported by manufacturers in their CSA A440 compliant labeling can be directly input into the calculations.

M e c h a n i c a l

Despite the challenge of all of these pending adjustments, this is a very positive change for our industry. For many years, it has been generally accepted that systems have been oversized, and the old F280 Standard facilitated this over sizing with its conservative approach to air leakage and ventilation.

The new standard employs more objective measures of air tightness, window performance and basement configurations and will empower contractors to rationalize both the size of equipment and distribution systems in both new and existing homes.

A natural progression into HVAC

I

t all began in 1976 when a small steel fabrication business launched by Wolfgang Schroeter started manufacturing steel railings in Barrie, Ontario, Canada. At that time, no one could imagine the incredible future that lay ahead for Wolf Steel Ltd. and eventually Napoleon® Fireplaces and Napoleon® Gourmet Grills.

Since the first wood stove rolled off the production line over 35 years ago, Wolf Steel's commitment was to be distinctive and successful in everything they do.

Napoleon® works with its customers designing and implementing features sought after by discriminating consumers around the world. Time after time Napoleon® has led the way with new and innovative patented technology: luxurious Gourmet Gas Grills, exclusive Infra-red grilling experience and some of North America's most advanced state-of-theart technology. Innovative engineering and design, advanced manufacturing techniques, dedicated customer service, outstanding product quality, and superior warranties distinguish Napoleon® from its competitors.

Napoleon® is an ISO9001 - 2008 registered company and operates with 750,000+ square feet of manufacturing

space and over 750 associates. We are North America's largest privately owned manufacturer of quality wood and gas fireplaces (inserts and stoves), gourmet gas and charcoal grills, outdoor living products and now the only gas furnaces made in Canada.

It was a natural progression into the HVAC market as the basic technology of advanced burner systems has been at the heart of every Napoleon product. At this point we invested in a new research & development division dedicated to the furnace line. We wanted to be unique in the industry, not a basic “commodity” to be bartered.

Different shape, different colour, a SureView burner system window so you can see the system working, UV light purifier for indoor air quality, totally sealed and insulated cabinet and LED lights in the upper and lower cabinets that come on automatically when the door is opened..... And very proudly the ONLY GAS FURNACES MADE IN CANADA, designed for our cold Canadian winters And to top it off, Napoleon® manufactures the most efficient 2-stage furnace available at 97.1%.

Key in the roll-out of our new heating and cooling division is the creation of a 300,000-square-foot logistics centre next year and the creation of 200 jobs within the next five years.

PROTECTING OUR POTABLE WATER SUPPLY O

ne of the hottest topics in plumbing circles over the past few years has been cross connection contamination, or more correctly, the prevention of cross connection contamination. The two terms that are used most when talking about protecting the public potable water supply are “cross connection control” and “backflow prevention.”

These terms both describe the protection of potable water drinking systems, but they are not completely interchangeable terms.

WHAT’S THE TESTING PROTOCOL?

Cross connection can be defined as an actual or potential connection between the piping on a potable water system and any source of pollution or contamination. Backflow prevention is a means by which a reversal of flow within a piping system can be controlled by the installation of a backflow preventer.

The current CSA standard, B64.10.1-11 part 8, documents the pass/fail criteria for backflow preventer performance. The CSA document is recognized throughout Canada and includes the field test requirements for pressure vacuum breakers, spill-resistant vacuum breakers, reduced pressure principle type devices, and double- and single-check valves.

The methods to test these devices may be found in the Appendix A of the standard.

AWWA administered training facilities follow this CSA method. ASSE procedures taught through union training facilities may differ slightly, however the procedure ends up with the same result. As long as the pass/fail criteria established in the CSA standard are met, either of these procedures would be considered acceptable.

The requirement for backflow preventers in Canada is enforced through municipal bylaw regulations in accordance with provincial building codes and the Canadian Standards Association (CSA) B64.10 document. Local municipal building departments should be contacted to verify their requirements.

Many building departments have established a cross connection officer who can provide all the pertinent information for a backflow preventer installation. A building permit will be required as alterations to the plumbing system will occur. A survey and engineering drawing defining the type and location of the backflow device will also be necessary to obtain a permit.

BACKWATER. BACKFLOW. What’s the difference?

Terms such as backwater valve and backflow preventer are sometimes used to describe the same thing, a device for the protection of a potable water supply.

There is a difference, however. A backwater valve is a one-way flow control valve installed in a drainage system to prevent the reversal of raw sewage.

A backflow preventer is a device to prevent the reversal of fluid in a potable water system. CSA standards identify seventeen types of backflow preventers. continued on page 36

BACKSIPHONAGE VS BACKPRESSURE Reversal of flow within a piping system occurs two different ways, due to either a backsiphonage or backpressure condition.

Backsiphonage is caused by a lower than atmosphere pressure. A good analogy would equate this to sucking on a straw in a bottle of pop. The sucking action lowers the pressure on the outlet of the straw and the pop, subject to atmospheric pressure in the bottle, is forced up the straw into one’s mouth.

In the case of a broken water main, a siphon action can establish itself when water at a higher pressure – due to its elevation within a building piping system – reverses flow as the result of the lower pressure at the main, thus drawing any fluid that the piping is connected to back into the potable water system.

Guelph, Ont., experienced a major contamination of its potable drinking water supply in August 1997 due to a low water main pressure and a much higher process pressure interconnected to the potable water supply within an industrial facility. It caused a lubricant to be pumped back into the city’s distribution system, rendering the water undrinkable for a few days until city works crews were able to flush the mains of the contaminant.

WHO NEEDS THEM? Where municipalities have enacted cross connection bylaws, the owner of an industrial, commercial, institutional or multi-tenant facility holds responsibility for the installation maintenance and testing of backflow prevention devices.

Reverse Osmosis Drinking Water System

The National Plumbing Code, Division B, subsection 2.6.2, Protection from Contamination, which has been adopted by a number of the provincial building codes, states, “Connections to potable water systems should be designed… so that nonpotable water or substances... cannot enter the system.”

Auto Water Shut-off

In effect, all persons engaged in plumbing would be responsible to ensure that if a connection is made to a non-potable source, an appropriate backflow prevention device is installed.

Installations and testing should only be performed by approved personnel. Municipal backflow prevention departments can provide a functions list of these individuals. They may include: licensed master plumbers, journeymen and apprentice plumbers under supervision, and fitters for fire sprinkler systems.

With the installation of a testable device, such as a reduced pressure principle type device, a double- or single-check valve, or a pressure vacuum breaker, a report of the valve’s performance will be required. Only individuals holding a licence would be accepted to perform the test and provide the report. These individuals would have completed a tester’s course through an accredited institution such as a community college, and be authorized through AWWA or the United Association of Unionized Plumbers. A municipal functions list can also extend repair and testing authority to certified industrial millwrights, as well as fire sprinkler and irrigation system installers.

HOT, WARM, COOL SO, YOU ARE ADDING A ZONE. WHAT TYPE OF SYSTEM RUNS WITH THE HOTTEST TEMPERATURES? In descending order: • Baseboard heat is the hottest; • Radiant floor system will typically operate at lower temperatures than baseboard; and • Snow melt systems will be the coolest.

HEATING ZONE

IS THE BOILER UP FOR IT? When an addition is made to a home’s hydronic heating system, take the time to run the calculations to prove the new addition will not exceed the capacity of the boiler. Don’t get caught assuming that the boiler can handle the addition.

n tough economic times like these, many consumers will expand their existing home rather than “move it on up” to a finished, larger home. Typical expansions include turning the basement into a bonus room for the kids, adding a bedroom for grandma, or turning the garage into a den – or better yet, that man cave you’ve always wanted. With these renovations, a new heating zone is often added, or an existing heating zone is expanded.

I

But there’s more to expanding a heating system than just tapping into an existing line and hoping for the best. The first step is a thorough design review, after which zones can be expanded or added to existing systems with minimal additional cost while maintaining the standard of comfort the customer expects. continued on page 40

M e c h a n i c a l

B u s i n e s s

That being said, the original boiler is likely large enough to handle the additional load.

When the original sizing calculation was run on the home, the boiler was chosen to meet the demand. The likelihood that the boiler would deliver the exact amount of input/output required is extremely low. If the home required 137,582 BTUH of heat a 150,000 or 200,000 BTUH input boiler is used, since no manufacturer makes a boiler with that exact amount of output. So odds are that the existing boiler has the fire power to meet the needs of an expanded system.

Beyond the boiler, it is necessary to consider some of the details of the addition. For example, what type of heat emitter is being used, and what are the design temperatures at design conditions? These two ideas go hand in hand. Will the new addition match or require higher or lower heating temperatures?

If higher temperatures are required, the boiler will need to be reviewed to see if it can meet the higher demand. If lower temperatures are needed, then the boiler will very likely be able to meet the extra demand. This becomes easier to install because the system’s higher water temperature can be easily diverted with a mixing valve to supply the lower temperature to the additional zones.

ADD OR EXPAND? Is it better to add a new zone or expand an existing one? In most cases, the better choice is to add a new zone.

The main reason for adding a new zone is temperature control. Take the example of adding a bedroom. If you expand the zone from another bedroom, the position of the zone control thermostat needs to be considered. Is it in the first bedroom? Is it in a shared hallway?

If the zone control thermostat is not shared, the new bedroom could end up being cold and uncomfortable.

FURTHER OPPORTUNITIES

It is worth a look at expanding a zone because it can be easier and less expensive to add to an existing zone, but the problem to overcome is zone temperature control. If the existing zone control will be able to monitor temperature evenly in both the old and the new zone, then expand away.

If not, attach a new zone to the manifold.

The addition of a new zone as part of a building expansion may be the perfect time to review the whole system and introduce new features that will benefit the entire building.

These controls can protect the system from boiler damaging conditions like short-cycling. Also, they can deliver energy efficiency saving functions like night setback.

The heating market is loaded with sophisticated electronic controls that can do much more than just control temperatures throughout a multi-zone system.

These controls that were once considered luxury additions are now commonplace and can be low cost additions with myriad benefits to the end user.

• A d d o r exp an d • A d d a b u ffer capacity is the key. The high mass boiler may suffer from a small zone addition the same as a low mass boiler, so the addition of a small buffer tank or low loss header may supply the extra volume of water the small zone needs.

Buffer tanks and low loss headers are gaining momentum in the marketplace.

They are more than devices that can be

used to fix an ailing system or to provide means to add additional zones. Buffer tanks and low loss headers are regularly installed as a part of the initial design.

They supply a much-needed mass of water to the system and they “decouple” the flow of the system from the flow of the boiler, allowing each portion of the overall system to operate without complication.

Check the minimum BTUH output of the boiler. Some boilers have modulating burners with a good turndown ratio. The maximum allowable turndown ratio on ANSI certified boilers is a 5:1 turndown, or boiler input from 20 to 100 per cent.

For a 150,000 BTUH input boiler, that is a minimum input rate of 30,000 BTUH. If the new zone has a demand greater than 30,000 BTUH, you are good to go. If the zone requires less, then a low-mass boiler will short cycle. Rather than replace the boiler, consider the addition of a buffer tank.

An often unforeseen problem is that a new zone may be quite small. For example, if the addition adds floor heat to a small bathroom, at some point this new small zone will be the only one calling for heat. If the low-mass boiler cannot reduce its BTUH input to match the small zone, the boiler will short-cycle, an operational problem that will shorten the life of the boiler.

UNLOADED VERSUS LOADED RECIPROCATING COMPRESSORS s it more efficient to operate one compressor at 100 per cent capacity, or two compressors at 50 per cent capacity? This question may come up when developing an algorithm for a programmable logic controller (PLC) for use on a multicompressor system.

FASTFACT

From these observations alone, we can see that the power consumption of two compressors operating at 50 per cent capacity will be more than one compressor operating at 100 per cent capacity. It follows that the energy cost will also be higher. One could calculate the energy cost by simply multiplying the power by the number of hours run time by the cost of the electricity. However, the effect of power factor should also be considered in these calculations.

Inductive motors always have a power factor of less than one since their inductive properties result in a reactive power component.

REFRIGERATION continued from page 44 It is important to understand how low power factor affects energy costs, as well as the impact that it has on the supply wiring and switch gear. Table 1 shows that the apparent power of the twocompressor scenario is almost 28 per cent higher. This does not necessarily mean that the energy cost will be 28 per cent more, however. In fact, this is not typically the case since utilities typically allow for some deviation from a unity power factor.

Most utilities charge a penalty for power factors that are less than a specified value. For example, the utility may pick a threshold limit value for power factor of 90 per cent to calculate the demand charges. The utility will then charge the user for the greater of the real kW used or 90 per cent of the kVAR used. Remember, kVAR is the reactive kVA portion of the load.

Assuming 3,000 hours of run time, and a kWh cost of 10 cents, our one-compressor system would have an energy cost of $7,851.91, while the two-compressor system would have an energy cost of $10,019.25.

In order to determine the power factor of a three-phase motor, it is necessary to find the apparent power by first multiplying the voltage by the current. Then multiply the result by a constant of 1.73. Note that this constant represents the square root of three. The final step is to divide the real power by the apparent power.

Within both scenarios of our example, the power factor is less than 90 per cent. However, operating the two compressor stages simultaneously at 50 per cent capacity results in a significantly lower power factor and is therefore the less favorable of the two scenarios.

Some motors have poor power factors to begin with. However, a lightly-loaded motor will also exhibit a lower power factor.

By performing a few calculations, it is possible to determine the most efficient method of staging compressors. It is also possible to evaluate the concept of power factor correction after understanding how the utility charges the equipment owner for its energy usage.

AVOIDING OVER-CORRECTION It is important to note that over-correction should be avoided. Some compressor manufacturers warn that power factor correction must be limited to a set percentage, like 95 per cent. There is a risk that high voltages could be present at the motor. This can be dangerous for both the motor and power factor correction capacitors. Additionally, it is very important that power factor is fully understood before attempting to correct it.

WHATâ&#x20AC;&#x2122;S POWER FACTOR? Power factor is the ratio of active or real power to apparent power. Real power is the actual power consumed by the motor while the apparent power is comprised of the actual power along with reactive power. Reactive power is the additional power that bounces back and forth between the voltage supply source and an inductive load, such as a compressor motor. Essentially, it is the power required to magnetize the motor. This occurs because the motor is fed from an alternating voltage supply.

The net power absorbed by the motor includes only the real power component. The reactive power is not actually consumed by the motor itself.

POWER FACTOR CORRECTION Depending on how a utility charges for its services, power factor correction may or may not provide a reduction on the actual electrical bill that would make power factor correcting devices worthwhile.

Power factor correction is a technique used that will effectively reduce the additional current carried on the wiring and components between the energy source and the motor due to the alternating reactive load.

This is very easily accomplished by adding a capacitance in close proximity to the load. Actually it does not have to be near the load, but placing it near the compressor reduces the distance that the reactive power has to travel. Theoretically, capacitors could be placed at the source, however the reactive power would still have to travel a long distance.

The capacitor bank accepts the reactive power sent from the motor and then returns this reactive power to the motor when it is required. This occurs every time the sine waves go up and down. Manufacturers of capacitive banks can provide assistance with sizing the correction capacitors. Calculating correction capacitance values is beyond the scope of this article.

HOT ROD’S HOW-TO:

Planning and piping for the

PERFECT PURGE

Eliminating MICRO-BUBBLES

You will never purge all the micro-bubbles or entrained air. The air purger in the system is there to finish off the job. As long as you have flow in every piping circuit or zone, the auto-purger will take care of the small air elimination detail.

I really like micro-bubble separators for this task. They work more efficiently and quicker than the older style ramp purgers. Micro-bubbles can cling to the heat exchange surfaces in the boiler or heat emitters, so it is important to get rid of all of them. The final microbubble elimination process can take a few days, or a week, as the boiler heats and drives every last bit of air out of solution.

I prefer to leave the auto fill valve on for at least the first week. And it is necessary to put water in behind the air that leaves the system. With today’s mod con boilers you need to maintain pressure to keep the low pressure switch closed. There’s nothing worse than a callback due to a fill valve that’s turned to the off position, and therefore is unable to maintain the system pressure. Again, this sort of call-back usually happens late, on a cold snowy evening.

W

ithout a doubt, one of the most frustrating parts of a hydronic startup can be purging the air out. This applies to brand new, piped-from-the-ground-up systems, as well as repairs and retrofits.

With a bit of forethought, maybe some doodling on a piece of scrap paper or a box lid, you can save hours of frustration. And keep in mind, the frustration found will be not only yours.

The homeowners will be frustrated if the system is noisy or not working. And in that second scenario, guess who will be getting a no heat call – yep, you guessed it, and you know you’ll be chasing down that air lock when you’d much rather be at that family dinner you get pulled from.

So, plan it; pipe it; and purge it! Happiness is an air-free hydronic system.

What’s in the pipes?

Purging into a bucket allows you to see just how much undesirable stuff was inside those pipes and tubes. If you allow the bucket to fill and spill over the top, it is not uncommon to see wood chips, sawdust, Teflon tape shards, copper shavings from reaming or cutting with a power saw, dirt, chips from threaded pipe, and maybe even some of your skin.

PLANNING an efficient purge

A hydronics system in modern application can contain many feet of piping, many zones and circuits, and some ups and downs. The application of radiant heating could present thousands of feet of small diameter tube for the air to hide in.

In all cases, the system can be piped with a few key valves to provide a fast and efficient purge.

Water or any fluid in the system will seek and find the path of least resistance. So your job is to encourage, or force, the fluid to take the path you have planned. This path will ideally lead to a nice full port valve that allows the air to escape. There are specialty valves on the market that allow you to install this perfect purge point with a minimum of fittings and installation labour. Some brands of these purge valves now come with press fitting connections. This allows them to be retrofitted without getting every drop of fluid out of the system, which soldering often requires.

Be Patient

Bob “Hot Rod” Rohr has been a plumbing, radiant heat and solar contractor and installer for 30 years. A long-time RPA member and columnist, he is manager of training and education with Caleffi North America. You can reach Hot Rod at bob.rohr@caleffi.com.

A sketchy solution I suspect you could keep very busy going around hydronic jobs and installing the perfect purge product and placement. Draw out your piping plan ahead of time for new installations. On repair calls, a site-built drawing may end up looking like a maze puzzle. The time spent on it is worth it though. You need to trace out every circuit in the system to be able to provide “road blocks” to make things flow your way.

A good purge could involve several minutes per loop. On larger piping systems or commercial jobs, you may need multiple isolation valves to break the system into bite sized purge sections. Unless you have a purge cart capable of high flow, and large valves to fill into and purge out of, valve the heck out of larger systems.

I would recommend a purge cart for new systems as you could pump a cleaning solution through the system to clean out any oil, solder flux, pipe dope, etc. Follow that cleaner with a clear water purge.

The bucket solution The method I use is probably easiest described via diagrams, so you can “see” the fluid path. Using a simple hydronic system as an example, perhaps a single boiler with multiple zones teeing off a header at the boiler, I like to install a full port ball valve equipped with a hose connection. Several manufacturers build such a valve in a one-piece assembly. And keep in mind, this could apply to a single pump, multiple zone valve installation, or a multiple zone pump install as well.

If the zones happen to be multi loop radiant zones, it is ideal to be able to isolate each loop. Trying to purge multiple 300-foot PEX loops will take a good flow of fluid.

To purge the system, install a boiler fill valve with a fast fill option, or build a bypass around the fill valve to use system pressure to speed up the purge process.

A spring clamp is a great way to ensure that the hose stays in the bucket. When the purge cycle first starts, you will be pushing large air pockets, and these tend to cause the hose to jump around. Keep the hose down in the fluid to see small bubbles being flushed out.

Some boiler fill valves have fast fill features built into them and do not require a bypass or manual fast fill lever. The intention is to provide a full pipe flow of fill water or fluid to push all the air out as it makes its route around the piping circuit.

I try to start with the longest loop first, if this is labeled or you know the loop lengths. Turn off all other loops at the manifold and purge one loop until it is air free. Use a short hose, maybe a 10-foot washing machine hose. The hose goes into a five-gallon bucket, near a floor drain if possible.

LOCATION OF HAMMER PROTECTION Protection should be placed at every valve or device that can stop the velocity flow of water. For cost reasons, this is not possible. As such, protection is usually placed at every riser, and between the last and second-to-last fixture on the branch that is being supplied by that riser. This is for horizontal branches not exceeding 20 linear feet. For branches exceeding 20 linear feet, protection should be placed at intervals not exceeding 20 feet.

In residential systems using copper or composite piping, all manufacturers recommend protection against water hammer. Protection is usually placed at the highest fixture. This is usually a tub and shower or a shower valve.

THE

EFFECTS OF WATER HAMMER

HIGHS, LOWSAND TROUBLES OF

WATER PRESSURE

• Annoyance caused by noise.

• Pipes may separate from their supports, clips and hangers.

• Other parts of the plumbing system may become damaged.

Water pressure; nobody gives it a second thought until there is too little, or too much.

For customers who live close to a water tower or water pumping station, adequate water pressure may never be an issue. For those in areas where the water pressure is low, there are few options. If the pressures seem low, call the local municipality to check the incoming pressure. Most municipalities will supply 206 kPa to 481 kPa (30 to 70 psi of pressure).

Beyond the municipal readings, hit the local plumbing supply shop and purchase a sediment faucet pressure gauge to check the pressure at the outside tap. Unscrew the garden hose, attach the pressure gauge, make sure no other fixture or appliance in the home is running, turn on the hose bib and read the gauge.

33% more water flows at 80 psi than water flow at 50 psi.

If the municipality deems the pressure to be adequate, but the homeowner is still not satisfied, check that the faucet aerator is not plugged, the main water valve is fully open, and that the household water pipe does not have too many bends, or sediment and calcium build up, and so forth. This is where your troubleshooting and investigative skills will be put to the test.

If your customer is on a well, you may have to adjust the pressure switch. In the old days, a 20:40 pressure switch was common. With the demand that we now have for water, it is not uncommon to install a 40:60, or even a 60:80 pressure switch.

A pressure switch senses the pressure in a storage tank and directs the pump to turn on at the lower pressure setting and turn off at the higher setting. If they are not on a well, you may need to install a pressure tank or a storage tank for them. continued on page 58

FINDING THE RIGHT PRESSURE What is the optimum pressure coming into a home? Normally it should be around 344 kPa (50 psi). Any less and it takes longer to fill up the bathtub, water the lawn, and so forth. This is very frustrating. What is also frustrating is when the water pressure is too high. Our plumbing codes state we are not to have a water pressure greater than 550 kPa (80 psi) in an occupied area.

WATER HAMMER PREVENTION

To paraphrase the code, where the static pressure exceeds 550 kPa, a pressure reducing valve should be installed to limit the maximum static pressure to no more than 550 kPa in areas which may be occupied.

With a high pressure water service, there is an increased chance of water hammer. Water hammer can be defined as the creation of severe shock waves of pressure in a closed-pipe system.

A pressure reducing valve should be installed to reduce high water pressure to a desired amount. A pressure reducing valve will allow a pre-set pressure at a given faucet or piece of equipment. In some cases, a much lower water pressure is required, sometimes in the lower teens. For example, a residential boiler only requires approximately six pounds of pressure per floor. High-rise buildings where booster pumps are installed may also need a pressure reducing valve.

This phenomenon is possible because water is minutely compressible, and therefore acts like a strong coil spring.

Water hammer itself is silent. Any noise is actually caused by pipe movement (vibrations). When water hammer occurs, a strong wave of pressure travels back through the piping system until it reaches some point of relief, such as air chambers or shock absorbers. This shock wave of pressure will surge back and forth between the points of relief until all the excess water hammer pressure has been dissipated. This action accounts for the noise and vibrations.

CONTROLLING WATER HAMMER A method of control must be provided to absorb shock and dissipate energy. Air or gas is the best way to absorb shock waves of pressure, as gas is highly compressible, allowing for maximum displacement in the air chamber (or shock absorbers).

One method of protection consists of built-on-site air chambers.

These work until air is absorbed in the water. If you make an air chamber, it is generally the same size pipe, and between 18 and 24 inches in length. And just to forewarn anyone making these, if you are using a composite piping material, most inspectors will ask for a brass plug, instead of plastic.

Manufactured shock absorbers use a cushion of air or an inert gas separated from the water by a diaphragm or bellows arrangement.

Building the

HAMMER

There are four conditions that increase water hammer:

WHERE IT BEGINS The most common cause of water hammer is the quick closing of electrical, pneumatic spring-loaded and manual valves, as well as operating reciprocating (piston) pumps too quickly.

1. Flow pressure: The greater the pressure; the greater the shockwave.

This is why water hammer arrestors are used in high-rises as opposed to air chambers. If an air chamber is manufactured on-site, it should be accessible and supplied with an air inlet (Schrader valve) and a stop and waste to drain and recharge the unit.

2. Flow velocity: Even if pressure is not excessive, an increase in velocity will worsen water hammer.

3. Pipe length: The greater the pipe length, the more time for pressure to build. Elbows reduce the influences of pressure waves.

PERFECT RING POSITIONING EVERYTIME Unique design equalizes water pressure at each outlet.

Made of durable Engineered Plastic (EP) for use in hot and cold residential PEX potable water piping systems.

Supplied mounting brackets allow for vertical or horizontal installation.

ANSI / NSF61-2008 ANNEX G Certified by NSF

For a complete line of AccucrimpÂŽ fittings and Equalfowâ&#x201E;˘ Manifolds see www.waterlineproducts.com

A quick-closing valve will produce a pressure that is 4. Frequency of stoppage: Frequent equal to 60 times the stoppages in flow at different points velocity of water that is in a piping system can increase the flowing through the intensity of water hammer. system. Most engineers use a velocity of five to 10 feet per second for residential designs.

If a house has 60 psi of pressure in the water service, and the engineer uses five feet per second of velocity, if a single-lever faucet were to be slammed shut there could be a pressure of 300 psi in that plumbing system.

Patent Pending

It is important to note that this pressure is only for a fraction of a second, and that the energy is dissipated very quickly as it travels back and forth between the cause location and a point of relief, but this will continue until the original psi equals itself, somewhere around 150 psi.

In a commercial building, the velocity can easily be in the 10 to 20 feet-per-second range.

CASE STUDY

B y Dar r en an d C o let t e C o o p er Darren Cooper is the president of Renteknik Group, a provider of renewable technology development, energy and environmental solutions, and the Canadian distributor of ClimateWell products. He can be reached at d.cooper@renteknikgroup.com.

WORKING WITH OLDER BUILDINGS One of the biggest hurdles to overcome for the pilot project was to find a willing client to invest in a technology that was unproven in Canada. With the help of government incentives, Shouldice was identified as a client who was not only interested in participating in the project, but could also provide a high-profile location for a largescale demonstration project to showcase the viability of solar cooling technology.

Like a majority of retrofits, the project was not without its challenges.

The Shouldice building was built in the 1940s and was originally a mansion house. The hospital opened in Toronto in 1945, but moved to the current location in 1953. Shortly thereafter, a medical wing was added to the existing building bringing the number of available beds to 89. The layout of Shouldice hasn’t changed much since the addition of that wing.

For the design and installation team, this meant dealing with tight spaces, the moving and removing of existing equipment to create space, and the inconvenience of having to install the new equipment in three different mechanical rooms.

On top of these integration issues, working in a hospital environment also had its complications. For example, each of the five operating rooms are under positive pressure, which made it difficult to work on the existing HVAC equipment. Site logistics for access, dust and noise control were also difficult.

SHOULDICE HOSPITAL GOES SOLAR FOR COOLING Shouldice Hospital in Thornhill, Ont., is home to one of North America’s most advanced thermal heating and cooling systems.

The system, consisting of 10 solar cooling chillers and 131 solar thermal collectors, is targeted to achieve a forecasted energy savings of more than 300 million BTUH of the cooling load (36%), 1.4 million BTUH of the heating load (44%) and more than 500 million BTUH of the domestic hot water production (91%). That translates into an offset of more than half the total energy load for the facility, and will reduce CO2 emissions by an estimated 150 tonnes per year – that’s equivalent to removing 28 cars from the road per year.

The triple state absorption unit at Shouldice has no moving parts at its core, uses no electricity for the heat exchange process and only a minimal amount for its control systems, uses no refrigerants and has an electrical COP of 333.

On a typical solar thermal system installation, the design is such that you should be able to heat almost 100 per cent of the domestic hot water from the sun in the summer months, but as the winter months come, the system produces much less energy. Alternatively, if the system is supersized to operate at maximum efficiency during the winter months, it will overheat and “cook” the system once summer comes back around again. By integrating a solar cooling system, that extra heat can be extracted and used in the summer to create air Located at 7750 Bayview conditioning.

Ave. in Thornhill, Ont., One of the biggest advantages of solar cooling Shouldice Hospital is is the system’s ability to reduce electrical equipped with five energy consumption during periods of peak operating rooms and 89 demand. This is particularly valuable considering the fact that the largest consumer hospital beds. It is known of electricity and major contributor to as a global leader in hernia brownouts in Canada is air conditioning during repairs. those hot summer months.

CASE STUDY continued from page 62 that a constant temperature difference between evaporator and reactor is achieved at that same time as excellent storage capabilities and high charge and discharge power are maintained. All the positive aspects of the solid substance and the liquid substance absorption principles converge into one technology.

A SOLID CHOICE The fluid salt solution reactor is efficient in its ability to absorb energy. It has a high charge and discharge power. However, since the fluid solution is efficient in absorbing heat, the reactor temperature continuously increases. As a consequence, the loading capacity of the system decreases to the point where the ΔT is no longer sufficient to run the process at all.

Moreover, the good heat absorption characteristics of the fluid also means it will not store energy efficiently. As a consequence, fluid reactors are designed for converting thermal energy to cooling in a continuous process and cannot, for practical purposes, be powered by a source of energy that fluctuates over time, such as solar energy.

The positive aspect of using a solid reactor substance is that it enables a constant loading ΔT between the evaporator and the reactor. In other words, the solid reactor substance does not increase much in temperature as it is charged. Energy is efficiently stored (in terms of energy per volume unit) in the solid salt, but has a very poor charge and discharge power.

The initially fluid salt solution reactor substance is crystallized into a solid state as thermal energy is added to the reactor.

Energy is stored efficiently and with practically no losses in the dried salt.

The practical implications of this energy storage solution are that a fluctuating source of energy can be used efficiently to deliver cooling and heating 24/7.

A CHEMICAL HEAT PUMP In simple terms, the triple-state absorption cooling system takes heat from the sun to create hot water. This hot water then serves as the main clean source of energy for the “charging” of the triple-state absorption cooling units, which are essentially chemical heat pumps.

This technology is unlike most conventional absorption chillers in that there is no pumping of a saline solution, nor is significant electricity required to run the unit. The unit works purely based on the movement of the water molecules from one cylinder (the evaporator), where the water is held as pure H2O, into a second cylinder where the water is combined with a lithium chloride based salt (the reactor).

Because of its poor heat conductivity characteristics there are very few practical applications for absorption machines based of a solid substance. The implications of the three-phase system are

COURTESY IN THE

TOP 10 THE TECHETIQUETTE PLEDGE

1

I will turn off my mobile phone during a meeting, meal or seminar to ensure I devote my full attention to the matter at hand.

Muting the device isn’t good enough, as I know the incessant buzzing will still irritate those around me, and tempt me to sneak a peek.

If I must keep my phone on for emergencies, I will let people know in advance that I might need to take a phone call. I will leave the room to answer such a call rather than slide into a corner.

DIGITAL AGE I

recently read an article that discussed the perils of performing surgery while talking on a hands-free device, and it got me to thinking about how much these devices have become part of our daily lives. Sometimes that’s for the better – it’s a phonebook and encyclopedia at our fingertips.

Other times, such as in the extreme case of the individual who launched a medical malpractice suit, they cause major problems.

4

When I receive an email, I will give the courtesy of a quick response even if it’s to say, “Great, thanks,” or, “I’ll get back to you.” They need not lie awake wondering if I got their email.

I will “reply all” only when I am absolutely 100 per cent certain that all are interested in or required to read my reply.

I will not list all of my contacts in the “To” or “Cc” field where private email addresses become public. Instead, I will remember to email myself and “Bcc” all those people.

I will write my emails in full sentences using capital letters where required, with proper punctuation, just as I was taught to write back in grade school.

8

9

Unless the recipient knows me very, very well, I will remember that email strips away all nuance, tone or subtleties that other forms of communication allow. As such, I will avoid being sarcastic or ironic, lest this be misconstrued and elevate into a full-blown conflict.

I will not put information, photos or jokes on social media, such as Facebook or Twitter, that I wouldn’t be comfortable with my boss, co-workers, customers or grandmother seeing.

The result? The following “Techetiquette Pledge.”

I will pay the same attention during conference calls as I would in a face-toface meeting, because I realize people can hear me typing, talking or snoring and consider this behaviour rude.

In the absence of clear directive from Miss Manners on these matters, I decided to reach out to friends and colleagues for their pet peeves when it comes to manners in a modern words.

M e c h a n i c a l

I will maintain a 10 foot distance from any other human being if I am talking on a cell phone. I realize this will rule out elevators, public transit and public washrooms as I know that stall doors are not walls.

7

What amazes me is how someone with perfect manners can become downright rude the moment their cell phone buzzes, rings or starts playing a dance tune. I’m sure you’ve seen it. In the middle of a conversation, the belt starts buzzing and the person grabs the device, ignores the person with whom they are having a face-to-face conversation, and starts texting as though there’s no one else in the room.

liminating callbacks is one of the keys to profitability, but while the statement carries a lot of truth, it’s always easier said than done. Wouldn’t it be great if there was one simple device that could reduce callbacks – and many problems in general – for all hydronic systems, large and small?

Such a device does exist and, actually, it’s not a giant secret. Micro-bubble air and dirt separators are produced by a number of manufacturers. While the use of these devices is becoming more common, selecting the proper micro-bubble and dirt separator for the job isn’t always crystal clear, nor is the right location for it, and where the unit is piped into the system has a lot to do with how effectively it will reduce those hydronic headaches and nuisance, midnight callbacks.

WHERE TO PUT THEM The lowest solubility of air in water is at the lowest pressure and highest temperature. In a hydronic system, this point is right after the boiler in a heating system and just before a chiller in a cooling system. This is the best place to install an air separator.

A few products on the market remove entrained air and dirt as their secondary function. Some units serve as a hydraulic bridge, connecting a primary loop with a secondary loop without allowing the flow in one loop to affect flow in the other.

Choosing the proper unit, installing it correctly and in the right location will increase component life and improve overall system efficiency.

HYDRONICS continued from page 72 enough. The best fix for impure, aerated water is best applied when the system is installed. Mechanical micro-bubble and dirt separation devices are the most effective way to avoid these problems by scrubbing out micro-bubbles and other impurities.

GETTING THE

AIR (AND DIRT) OUT

Air-entrained water and impurities decrease the efficiency and lifespan of heating equipment, pipes and system components, causing more callbacks than many professionals care to admit.

Ideally, we know that water in a hydronic system is best when it’s “dead.” But air makes its way in through boiler makeup and feed-water inlets, making the system’s oxygen-rich water more corrosive with each new introduction. Air is also the chief cause of noise within hydronic systems.

Unfortunately, some installers have the misconception that air vents do the job well

Air vents too often give system designers or installers a false sense of security. Air within a piped system may not collect where the air vents are placed, however. These devices are designed to remove larger volumes of air when pockets form at high points in the system. This may not, however, capture as much air as desired, and there is still the issue of removing dirt or minerals.

If impurities are present in a system, or are routinely introduced with makeup water, accumulation can lead to a wide variety of problems. Flow is chocked off as pipes accumulate mineral deposits, thermal efficiency suffers, valves and circulators can gum up. Before long, late-night, midwinter callbacks could be commonplace.

To effectively remove debris and micro-bubbles, which can be an ongoing challenge, a micro-bubble and dirt separator is needed.

The devices are a more substantial piece of hardware when compared to the air vent, but they’re not expensive. Depending on the volume of the hydronic system, the profit lost by one callback could cover the cost of a high-quality micro-bubble and dirt separator.

LEVELS OF PROTECTION When it comes to removing air from a hydronic system, there are really only three options. Some refer to them as “good, better, best.”

The “good” option is an air scoop. This technology hasn’t changed in many years. Usually inexpensive, air scoops are mounted inline in the piping and are designed with an enlarged area in the upper portion of the unit to trap air as it travels through the pipe. The air is then vented through the top of the unit via an air vent.

The “better” option is a tank-style commercial air separator. These are designed to provide a large area for the system fluid velocity to slow, allowing air to rise to a vent. This style eliminates air that is entrained in the water, as well as air that is free in the pipe and present as bubbles in the water.

A micro-bubble and dirt separator typically has a large chamber that Options for this style of air separator include a allows the fluid velocity to slow, and a coalescing media, often pall rings, strainer to remove large debris, in addition to air. beads or a screen, that “scrubs” the water. This media creates the large Tangential separators, which create a vortex inside surface area that allows micro-bubbles to cling to it. the unit are also available but are subject to

SCRUBBING BUBBLES

velocities in the pipe being maintained to create the vortex.

The “best” option is a true micro-bubble and dirt separator. These run the gamut from two inches to 30 inches in size, all the way up to 36 inches or more from a custom shop. They use a coalescing medium to collect air and dirt for removal.

The micro-bubbles fuse with each other on the media and increase in volume until they’re sufficiently buoyant to rise to the top of the device.

Then, the air is released through a float-operated automatic air vent valve.

The media serves double-duty. Not only does it collect entrained air, but it’s designed to impede the flow of debris and impurities. They collide with media and fall to the base of the chamber where they can be blown down and ejected.

JUSTICE PREVAILS IN

Cowansville HVAC PROJECT T

he Palais de justice de Cowansville has been a mainstay in the community since

the 1850s. As with many historical sites in need of renovation, energy efficiency wasn’t exactly a strong point for this still-functioning courthouse.

This put more pressure on the design team at Dessau Inc.’s Longeuil office to find creative ways to develop an energy-efficient heating and cooling system that wouldn’t compromise the integrity of the building. After much research, the decision was made to go with a high-efficiency geothermal heat pump and duct system.

One of the goals of the project was to recover as much energy as possible before using the geothermal system. To that end, simulation models were created to study different HVAC scenarios. The models not only helped engineers determine that geothermal energy was both economically and technically feasible, they allowed them to analyze the building’s hourly heating and cooling loads over the course of a year. Simulations further helped designers choose heat recovery systems that helped reduce the building’s needs before tapping into geothermal energy.

Given it was built in the mid 1800s, the Cowansville Courthouse had a low performing building envelope. Not surprisingly, it had no insulation, and until recently, heating was provided by a boiler with hot water radiators.

When the Société Immobilière du Québec (SIQ) decided to engage in a major renovation, there was a lot to consider on the HVAC front.

“We decided to recover year-round heat rejection from the telecommunications room,” says Marco Freitas for Dessau who was in charge of mechanical design for the project. “We decided to try to recover the available energy in the building, before tapping into ground source energy. We optimized the building design as much as possible.”

Insulation was a must to avoid the risk of condensation in the stone walls which could lead to stress cracking from ice and deterioration.

However, dew point calculations revealed that if the walls were insulated to R-20, there was a risk of condensation within the stone walls. It was decided to insulate them to R-14 instead.

The simulation also confirmed the value of using an enthalpy wheel to recover heat and transfer wasted energy from the exhaust air to incoming fresh air. “This reduces fresh air heating, cooling and humidification loads,” Freitas explains. continued on page 82

CASE STUDY continued from page 80 THE SAVINGS STORY The courthouse’s efficient HVAC design is a winner by all accounts. To date it has reduced energy consumption by 36 per cent (a 220,000 kWh/$30,000 a year savings).

In addition to the heat recovery and geothermal efficiencies, energy savings were increased with programmable electronic thermostats. Room temperatures were set back 4°C for cooling or heating during times when the building wasn’t occupied. An automated system also allowed for the divergence of components such as domestic hot water during peak energy demand periods.

CO2 levels are monitored and additional fresh air is supplied when needed by raising the fan unit’s speed using a variable frequency drive to improve air quality and reduce energy consumption.

While energy-efficient systems can be more costly than traditional HVAC equipment, a $40,000 subsidy from Hydro-Quebec, along with some creative work on the part of the design team to narrow overrun costs to $150,000 compared to a traditional hot water boiler/chiller design, has resulted in a projected payback period of just over three years.

BIG IDEAS Even though geothermal was the right foundation system, there were some unique challenges to overcome. The original plan had not taken into account the cost and space requirements of a geothermal system. “The space and budget restrictions eliminated the possibility of building a new mechanical room,” says Freitas. “Also, we were not allowed to place equipment on the roof.

So we had to work with what was available to us.”

Other interior challenges presented themselves. For example, suspended ceilings could not be installed in low ceiling areas, which significantly limited work space. “In many of those areas we would normally just installed visible ducts and pipes,” he adds. “However, you can’t do the same with heat pumps.”

At first it seemed impossible to fit all the equipment needed into the available

82

M e c h a n i c a l

space and budget, Freitas reports. To address the issue, the team sized the ground loop to fit the building’s cooling capacity, thereby eliminating the need for extra cooling equipment. The closed loop system was made up of 15 boreholes at a drilling depth of 500 feet (152 metres).

Each borehole was individually connected to a collector to allow for future expansion.

Terminal electrical coils were used instead of a boiler for auxiliary heating to supply additional heat to the coldest areas of the building. “That saved us a lot of money and space. And it provided us with some room to group thermal zones,” Freitas explains.

In lower ceiling areas, the team utilized existing spaces, such as the old prison cells or the six-foot-high (1.8 metre) service basement. The fresh air ventilation unit and enthalpy wheel were placed

B u s i n e s s

0 4 . 1 2

behind bars on the last floor of the old prison ward.

Duct and piping was also optimized to keep costs and space requirements at a minimum. And, because the old bearing walls were unsteady, the number of holes that could be drilled through them was restricted. Therefore HVAC and structural engineers put their heads together to find creative ways to lay out ducts, piping and heat pumps. Where possible, they used existing holes that were originally dedicated to hot water plumbing.

“Working within an historical site was an interesting and challenging project,” says Freitas. “But with some creative thinking we were able to create a system that would save energy and improve efficiency without compromising the integrity of this important historical community landmark.”

with your invoice? More importantly, and most troubling, you’re not sure how to avoid the same trouble with this new estimate.

How has the contracting industry let such systemic problems persist for so long?

It’s clear that operating construction businesses has inherent challenges, like transient job sites, multiple customers, managing sub-contractors, producing accurate estimates and avoiding paperwork bottlenecks. It all seems so unwieldy and inexact. Whether you’re a mechanical or an electrical contractor, the operational challenges are all the same, and they boil down to the management and reporting of time, inventory and project controls.

The good news is that there are technology platforms available that can solve these problems. The right software package can drastically improve operational efficiency, expedite payroll and billing, facilitate accurate estimates and real-time reports (so you can report on productivity throughout the job), accurately estimate percentage complete, and reference precise and accurate data when generating estimates for future work.

The goal is to alleviate traditional headaches, like delayed billing due to missing or slow-tobe-filed paperwork, miscalculations due to transcription errors, and unnecessary effort on estimates and job tracking.

CONQUERING FEAR OF TECHNOLOGY

For those new to technology who aren’t used to using it either in personal life or as part of business, it’s important to keep the advantages of technology adoption in mind and to stay focused on the many benefits that a business can reap by incorporating technology.

The fact is, contractors who realize that the problems traditionally associated with reporting and billing can be eliminated using the right technology will come out ahead of their competitors and will better weather current challenging economic conditions.

it’s imperative that contractors adopt technology solutions that reflect how things work in our industry.

But simply adopting a technology solution with a field-in approach is not sufficient. Many field-data-capture solutions will send raw data in from the field but a contractor’s software package also needs to process this data, and smoothly integrate it into the existing back-office accounting and reporting software to provide for accurate labour and materials management, as well as timely purchasing and invoicing.

Software solutions that capture data in the field and instantaneously route it into back-office systems eliminate paperwork headaches and transcription errors, and speed up the process of billing and payroll. They also provide accurate, realtime, actionable information that contractors can use to better manage their crews and assess variation on materials, labor and other variables.

Using a software platform that provides such visibility in real time enables contractors to provide specific information to their customers about issues that may have impacted productivity.

In some job environments, weather may play a role, cost of materials may change suddenly, labour rates may change, or there may be other dynamic market factors. Understanding exactly what is happening in the field at all times delivers a significant competitive advantage to any contracting company.

PUBLIC DRINKING WATER: Selecting the right device for the right space FOUNTAIN OR COOLER? • Is it an indoor or outdoor application?

How will the local, seasonal climate impact the equipment? For parks and other outdoor venues, drinking fountains are commonly installed and equipped with freeze resistant valves to ensure year round functionality.

• Type of facility? Fitness clubs, for example, will typically utilize a water cooler to offer chilled water to patrons.

Additionally, is the facility prone to high traffic or extreme use (i.e. vandalism)? In these cases you may want to consider a heavy duty, stainless steel drinking fountain with fewer mechanical components.

eady access to clean, safe drinking water outside of the home is something that most Canadians take for granted. Whether at work, school or play, every non-residential facility has some type drinking water available. There is a wide range of products available, so how do we select the right device for a particular application.

R

The average person will interchange the terms water cooler and drinking fountain without really understanding the difference, or why it is best to use one versus the other. In the plumbing world, a water cooler is defined as a device that chills water (to approximately 10°C) and then delivers it to the end user; either through a bubbler, manual or sensor activation. A drinking fountain, on the other hand, simply delivers water at the ambient temperature.

• Ambient water temperature? In Canada we generally have adequately chilled ground water so an additional chiller may not be necessary.

• Access to electricity? A water cooler requires refrigeration and electricity, so in areas where this is not possible fountains are the way to go.

FOR WANT OF A SNEEZE GUARD We’ve all been in a school, airport, mall or arena in need of a quick drink of water, only to have the person in front of you cough and sneeze all over the bubbler! No thanks, a dry mouth isn’t so bad after all!

As germ transfer and bacteria become an even greater focus in our world, sensor-operated products are becoming the norm in public spaces. Water coolers and drinking fountains are no different; there is currently a wide range hands-free, sensor-operated product that fit the needs of any type of facility. continued on page 90

Additionally, many manufacturers are offering products treated with antimicrobial compounds to assist with the reduction of germ transfer. While sensor-operated products may have higher upfront costs than the manually operated versions, they provide a better overall user experience and in the case of healthcare facilities, sensor-operated products can lower the risk of secondary infections which can ultimately have an enormously negative impact on the facility.

When it comes to indoor fountains, manufacturers have come a long way from the old white, porcelain school fountain. Features like sculpted bowls and PVD finish options mean that an architect or designer can add a fountain that complements the rest of the interior space.

STYLE VERSUS FUNCTION Drinking fountains, whether for indoor or outdoor use can provide an architectural flair that will boost the design features on any project. For outdoor fountains, there are a variety of cast concrete or powder coated metal options in multiple colours that can match up to the overall feel of the outdoor space being designed.

Functional features like dual height bowls and even pet bowls make the outdoor fountain suitable for any application.

Designer features donâ&#x20AC;&#x2122;t mean making any sacrifice to serviceability however. Common features on todayâ&#x20AC;&#x2122;s drinking fountains are low-profile designs with a trap located outside of the wall. This eliminates the need for an access panel and allows maintenance staff easy access. Additional features may include a fully-serviceable cartridge located inside the push button, making flow adjustments very simple.

PVC Flame & Smoke Rated Specialties For Noncombustible Construction With the increasing use of PVC systems for high rise residential, commercial and institutional applications, Canplas FR-PRO now allows the specification of the gravity drainage system all the way to the fixture or termination.

Canplas FR-PRO has inherent flame and smoke performance engineered into every fitting. As such, the drainage system can now be completed in PVC using standard solvent weld installation practice. In addition there are fewer material transitions plus all the established benefits of using PVC as a cost effective replacement for traditional materials such as cast iron and tubular brass. The Canplas FR-PRO range is fully compatible with existing 25-50 PVC products and covers applications from roof and floor drains, to bath waste & overflow kits and urinal flanges.

TASTE, ODOUR, CLARITY

THE ENVIRONMENTAL IMPACT

In Canada, access to safe drinking water is a basic right, and allows us to drink the water that comes from the tap without risk of harm. But this right does not go so far as to require that the water be aesthetically pleasing, in terms of taste, odour or clarity.

In order to ensure the clear, tasteless, and odourless (CTO) requirement that most people prefer, it may be necessary to look at point-of-use (POU) filtration. There are a number of options for POU filtration to eliminate CTO issues, but the least expensive and most common method is the use of carbon as the filtration medium.

Carbon-based filtration accomplishes the following: • Removes chlorine; • Improves overall taste; and • Remove unpleasant odours.

Carbon filtering uses activated carbon to remove contaminants and impurities.

This is accomplished through a process called adsorption. Adsorption, not to be confused with absorption, is the accumulation of atoms or molecules on the surface of a material. This process creates a film of the adsorbate on the adsorbent's surface. This type of filtration lasts a long time and offers a very high level of protection from the elements that make tap water unpleasant to drink.

When exhausted, it is perfectly safe and acceptable to dispose of carbon filtration media (cartridges) in normal landfills.

The “ban the bottle” movement has taken hold in many municipalities and educational institutions across the country, but remember that easy alternatives must be available to support the movement away from the bottle. Sensor-operated filling stations are not the only option, most manufacturers provide glass filler options for both water coolers and drinking fountains, all to encourage the use of personal, refillable containers. A separate, manually activated spout located on the deck of the fountain or cooler provides dual access for use to either drink from the bubbler or fill up at the spout.

Quality time on the show circuit I normally only have 3 or 4 hours available to me when I manage to spring myself free to attend a trade show. Any advice on how to make the best use of that time? What do you look for when you are going through the aisles? And is there much benefit from planning to attend for more than one day? Jason N., Ottawa, Ont. Roger Grochmal is the president of AtlasCare in Oakville, Ont. To submit a question about your company, business practices, or the industry in general, send an e-mail to Mechanical Business magazine’s editor, Adam Freill, adam.freill@ mechanicalbusiness.com.

A three-part plan There are three equally important parts to a trade show: people, technology and education.

PEOPLE There is a lot of movement in our industry, and trade shows are a great opportunity to find out who is representing which company.

In an age where most of our conversations take place through email and texting, face time is incredibly valuable.

People like to do business with people they know and trust, and so getting out there and doing a bit of networking at trade shows can go a long way.

The first day of any trade show is generally very busy and sometimes it can be hard to get some face time with people you would really like to meet. I find that the second and third days are often the best. This is particularly important if you only have a few hours to spend.

TECHNOLOGY Besides spending time at select booths, I also walk the entire show to get a sense of what is popular and what is not. I was at a home show a couple years ago and it seemed that every second booth had someone talking about solar energy. Take a tour of the entire show to see what up-and-coming technologies we’re going to see coming at us from multiple directions.

I recently attended the AHR Expo in Chicago and there was a solid Canadian contingent there. Every booth seemed to have controls and/or a web-driven control strategy tied into smart phones. The future is here.

CHOOSING

MOTOR SPEED CONTROL

DESIGNER’S NOTEPAD For new VFD motor installations, always choose “inverter duty” or “inverter ready” motors.

CHOOSING A CONTROL Armed up with the brief introduction to VFD technology (see sidebar: How a VFD works), here’s what to consider when choosing a motor speed controller. Always consult the motor and VFD manufacturer for compatibility issues, and save time by having the answers to these eight questions ready.

1. NEW OR EXISTING INSTALLATION? For new installations, we are free to choose pretty much whatever we want. However, for existing installations, our choices will become more limited, based on what we have to work with. For example, if we have an existing pump with three-phase “Inverter Rated” motor, we probably won’t replace the entire pump. It is likely easier to just choose a compatible VFD. 2. AC INDUCTION MOTOR OR ECM? Traditional AC induction motors range from fractional to hundreds of horsepower, whereas the electronically commutated (ECM) motors that are gaining traction in North America range up to two horsepower.

The advantage of the ECM motor with integral drive is that the drive selection and

96

M e c h a n i c a l

integration is done for you. The drawback, however, is that for larger pumps the initial cost is significantly more than for a traditional pump with discrete VFD. Additionally, when either the drive, motor, or hydraulic portion of the pump fails, usually the entire unit must be replaced. Ideally, for all but the smallest of disposable pumps, the drive should be easily replaceable in the field for servicing.

3. SINGLE-PHASE OR THREE-PHASE AC INDUCTION MOTOR? VFDs are generally designed for three-phase motors, and can easily handle a 2:1 and sometimes even a 3:1 speed turn down.

(Remember that in our last article we learned that a 50 per cent speed reduction resulted in 87 per cent reduction in power

B u s i n e s s

0 4 . 1 2

consumption.) There are some speed controllers available for single-phase motors, but generally these cause the motor torque to fall off abruptly and therefore the range of speed reduction may be limited. (Expect to see improvements in this area in the near future.)

4. IS THREE-PHASE POWER READILY AVAILABLE? Some VFDs are capable of accepting a single phase power supply, and invert to threephase power for the motor connection. For an existing installation, where the single-phase motor (less than one horsepower) is going to be replaced with a three-phase motor anyway, using a phase converting VFD may be less costly than running three-phase power to the location.

• C h o o s i n g a c o n t r o l • C h eck fo r co r r ect io n

HOW A VFD WORKS The fixed speed of an AC motor is dictated by the frequency of the supply voltage, the number of poles in the motor, and the percent slip (typically around three per cent) caused by the application of the load.

The frequency of the distribution electrical supply is fixed (60 Hz in North America or 50 Hz in some overseas countries) and must be maintained within a fairly tight tolerance (in part, so as not to change the speed of all fixed speed motors on the grid).

Therefore, it is necessary to come up with a way to change the supplied frequency to the motor, isolated from the distribution supply.

To achieve this, the VFD converts the AC supply power to DC and then chops the DC power back into an AC signal of required frequency and voltage, typically using Pulse Width Modulation (PWM).

CHECK FOR CORRECTION Remember to check for existing power factor correction in larger facilities. When retrofitting a site having fixed-speed induction motors with VFDs, some capacitor banks may need to be disabled.

Some VFDs can skip the mechanical resonant frequency of the motor, which could otherwise cause excessive vibration, noise and damage.

VFD supplied power can cause standard OEM motors to run hotter which, in some cases, can cause the winding insulation to break down and the motor to fail prematurely. Ensure the motor insulation is up to the job before retrofitting a VFD to an existing fixed speed motor.

Interestingly, this also isolates the inductive load of the motor windings from the supply – in fact, the VFD may present a capacitive load to the supply. This is the opposite to what happens with a fixed-speed motor.

For this reason, many VFDs include built-in power factor correction or compensation.

“Inverter rated” motors are compliant with standard NEMA MG1 Part 31, to help withstand the voltage spikes that can be generated by a VFD.

5. WHAT IS THE REQUIRED MOTOR VOLTAGE?

VFD non-sinusoidal voltage output, and you could encounter some significant problems.

IP-66 VFD enclosure for outdoor mounting locations.

Most VFDs provide line-to-line voltage and must be ordered to suit the required line voltage of the motor. Smaller VFDs are typically limited to 120 / 240Vac.

7. WHAT ARE THE MOUNTING REQUIREMENTS?

8. HOW IS THE VFD TO BE CONTROLLED?

6. WHAT IS THE MOTOR RATING? Take a close look at the motor nameplate for the FLA (full load amperage) and check the pump curve for the power (hp) needed to run at the maximum operating point (head and flow). Some motors have a service factor that can run as high as 1.75. This means that the motor can be run at 75 per cent higher than the rated horsepower. However, in doing so, the motor will run hotter and will likely require more frequent servicing. Add to this the increased motor heating caused by the

In general, you want the VFD mounted as closely as possible to the motor, to minimize the cable run. Some VFDs provide integral line reactors, however, additional harmonic filtering may be required.

For longer power cable runs between the VFD and motor, pay close attention to the cable and motor input impedance, as a poor match can result in very high (damaging) voltage spikes to the motor.

Some manufacturers supply pumps with the VFD mounted right on the motor.

Alternatively, you may wish a DIN rail VFD enclosure for mounting in a panel, or even an

M e c h a n i c a l

VFDs can control the motor speed based on a manually-set fixed speed (either via keypad or potentiometer), an analogue input (0/210Vdc or 0/4-20 mA) from a sensor or separate controller, or by digital communications from a BAS (Building Automation System), or any combination thereof. Also consider any special I/O requirements such as for a Hand/Off/Auto switch, or a “run enable” discrete input.

Some VFDs provide for sensorless motor speed control based on the motor current and rpm versus load profile mapping. (How to control the VFD will be the subject of future articles.)

ELECTRICAL SAFETY ON THE JOB ecently, there has been an increased awareness of the dangers associated with working on electrical systems.

This is due to serious injuries that have occurred in the Canadian workplace involving both electrical shock (direct contact) and arc flash events.

R

The Canadian Standards Association (CSA) has developed a standard designated as Z462. This standard’s title Workplace Electrical Safety is a comprehensive best practice document that specifies requirements unique to the hazards associated when working with electrical energy. Eventually, provincial, territorial and federal governments may decide to enforce Z462 in regulations, but there’s no reason to wait until it is the law of the land.

CALL ON THE

EXPERTS

M e c h a n i c a l

If you are working on electrical equipment operating at 50 volts and higher, you should take every precaution to protect your company’s most valuable assets.

Remember, it is important to understand that electrical safety encompasses protection against shock, flash and blast.

These hazards have their own requirements for protection.

Careful attention should be paid when selecting PPE for each of these hazards to ensure they integrate properly and offer the worker the maximum protection available.

HVAC/R safety programs The primary focus of an electrical safety program, especially for those in the HVAC/R trades, should be the establishment of an electrically safe work condition, meaning that equipment is isolated, locked out and verified that it cannot be re-energized while work is being performed.

Creating an electrically safe work condition is the first line of defense against all electrical hazards.

The Z462 standard does not constitute a comprehensive and effective electrical safety program on its own. The most effective design and implementation of an electrical safety program can only be achieved through a joint effort involving electrical subject matter experts and safety professionals.

If you have employees working on electrical equipment, these employees are potentially at risk for serious injuries.

USE THE RIGHT PPE To conduct a shock hazard analysis it is necessary to know the voltage to which employees will be exposed and the shock boundary requirements for both qualified and unqualified employees. Specific personal protective equipment is necessary to minimize the possibility of electric shock.

Arc flash hazard analysis includes both arc flash and arc blast hazards The goal is to determine the arc flash protection boundary and the personal protective equipment that employees within the arc flash protection boundary shall use.

Both the shock hazard analysis and the arc flash hazard analysis will identify the appropriate personal protective equipment (PPE) to be worn whenever energized electrical work must be performed.

Two methods can be used. The first is to conduct an incident energy analysis involving engineering calculations and physical inspection of the electrical system. This determines the incident energy exposure of the worker in cal/cm2.

Typical types of protection from an arc flash hazard include arc rated (AR) coveralls or shirt and pant combinations, as well as hard hats and face shields.

All of these items are given an arc rating which must be used to ensure the PPE is greater than the potential hazard the worker may be exposed to.

The second method uses CSA Z462 Hazard/Risk Category Classifications. This is also known as the table method. Use of this method is only permitted when the available fault current and clearing time of circuit protection devices are known.

Insulating rubber gloves and leather protectors are required to be worn when working on exposed energized equipment at 50 volts or more. Other items, such as insulating rubber insulating blankets, insulated hand tools, all help to reduce the chance of shock or electrocution.

For both these methods, intimate knowledge of the circuit protection devices (breakers and fuses) is required, and these devices should be maintained to the manufacturerâ&#x20AC;&#x2122;s instructions or industry standards.

Workers exposed to electrical hazards need to be trained in the release of victims from contact with exposed energized conductors. An insulated rescue hook should be available where appropriate.

TOOL TIPS

Hotter than the

SUN

hen it comes to working in sheet metal, having a good set of snips is a must, but when you are dealing with a lot of straight cuts, or curves that are not too tight, it is nice to speed up the job and save some of the physical effort by turning to a good quality electric shear.

W Photos: NASA

Simply put, an electric arc is a short circuit through air. When insulation or isolation between conductors is breached, or can no longer withstand the applied voltage, the air between the conductors becomes ionized.

Ionized air will conduct electricity and an arcing fault occurs between those conductors. An electric arc is one of the hottest things known to man.

Temperatures at the arc terminals can reach 20,000°C, or more – that’s several times the temperature of the surface of the sun.

Powering up duct cuts

DE-ENERGIZE & LOCK IT OUT In the hierarchy of safety, personal protective equipment (PPE) is always considered to be the last line of defence. It is always preferable to eliminate the hazard than to accept the risk and use PPE to mitigate the hazard.

In terms of electricity, to eliminate the hazard would mean to isolate the equipment to be worked on from all sources of power. It is not enough to simply flip the power switch. Tagging and locking out the equipment while the work is being done might be a pain, but it could save a life.

ProNOTES

Do not exceed the recommended capacities of the tool.

When cutting, hold the tool so that the blades are in firm contact with the material for the fastest cutting. Apply even pressure. Too much pressure will tend to jam the tool or cause a rough cut.

And pay attention to your cutting angle to ensure that you are producing a clean, efficient cut.

The material clearance is important. Go with the manufacturer’s recommended clearance, but as a rule of thumb, using 20 per cent of the thickness of the material will normally work.

The sharpness of the cutters is also important. Sharp cutters minimize stalling. Do not use dull or damaged cutters, or accessories not intended for your model of shear.

Do not force the shear through the work. If the shear does not cut correctly, recheck for proper blade clearances and dull blades.

UNIVERSAL DESIGN

B y Gar r y S co t t

ACCESSIBILITY for all

Garry Scott is the vice-president of wholesale marketing with Moen Canada. He can be reached at garry.scott@moen.com.

PRINCIPLES OF ACCESSIBLE DESIGN When beginning a project, it is important to keep seven key principles in mind. These were developed by the Center for Universal Design to assist manufacturers, builders and consumers in keeping accessibility and practicality top of mind.

nsuring that a public space can be used by everyone is the underlying goal of universal design. This concept is challenging designers, architects and engineers to rethink the fundamentals while considering how an environment can be designed or adapted to accommodate people’s changing needs, while incorporating new aesthetics that aren’t prohibitively expensive or appear institutional.

E

Adopting universal design is becoming the rule in today’s construction industry – not the exception.

Make sure your commercial and residential designs offer features that make the space adaptable for all consumers, regardless of age and ability.

1 2 3 4

Equitable use - The design is useful and marketable to people with diverse abilities.

5 6 7

Tolerance for error – The design minimizes hazards, accidents or unintended actions.

Flexibility in use – It accommodates a wide range of preferences and abilities.

Simple and intuitive – The design is easy-to-understand, regardless of user’s experience, knowledge or skills.

Perceptible information – Necessary information is communicated effectively to the user, regardless of sensory limitations.

Low physical effort – It can be used with minimal effort.

Size and space for approach and use – Regardless of user’s stature and mobility, the design is appropriate for approach, reach, manipulation and use.

â&#x20AC;˘ I n c o r p o r a t i n g the principles

INCORPORATING THE PRINCIPLES The principles of universal design help ensure the design for each space is usable and accessible. For companies and builders interested in implementing universal design principles, but concerned about cost implications, it is important to note that small changes can make a big difference.

A great place to start an accessibility overhaul is in the place with the most danger zones â&#x20AC;&#x201C; and likely the most room for improvement â&#x20AC;&#x201C; the lavatory. To ensure a space can accommodate users of all ability levels, mount bathroom sinks no higher than 34 inches above the floor, with knee clearance that is 27 inches high, 30 inches wide and 19 inches deep. Clear floor space and insulated pipes are a must.

By incorporating these products in the initial design, a business can avoid the high costs associated with renovating or reconfiguring the space to be able to install specialized units that ensure the lavatory can be easily accessed and used by all, regardless of mobility or physical challenges.

Commercial products that address a universal audience, like extended-reach faucets or hands-free sensor-operated flush valves and faucets, are offered in the commercial products market to affordably cater to the needs of consumers.

PROPYLENE VENTING:

ARE YOU USING IT? efore you flip the page, no, I don't own stock in the product. But if you haven't been exposed to polypropylene (PP) venting for your boiler or furnace installations, you might want to look into it. All indications are that this will be a growing option as we move forward.

B

PP venting is starting to become available in North America. It's been used in Europe for more than 20 years, has a higher temperature rating than CPVC, and has finally passed all the certification required to be sold in Canada.

Polypropylene venting does not use glue. The systems use press-fit gaskets lubricated with water or a water-based lubricant. The venting can be disassembled and modified after it has been installed, and thereâ&#x20AC;&#x2122;s no wait time necessary between vent assembly and boiler commissioning as there is no glue to cure.

Since the systems use gasket-style fittings that allow for expansion, there is less noise associated with the vent run as the heating appliance cycles on and off. The gasket connection also means that telescoping fittings can be made. Flexible vent is available for vertical runs, and concentric PP vent is also available.

Polypropylene is non-toxic, even when burned, and can be readily recycled.

The lightweight material comes in shorter lengths than PVC or CPVC, but that means that it will fit into smaller service vehicles.

A TIGHT FIT I've handled PP venting myself, and despite some initial concerns about the gaskets, I came to realize just how well sealed the joints become. The demonstration sample that I had a chance to test out became quite snug when we tried to pull it apart.

Okay, okay â&#x20AC;&#x201C; it's great stuff. But new things always have problems! What are they?

Well, first of all, PP venting requires both supports and locking bands, partially because the venting is more lightweight, and partially because North American codes require it. With shorter pieces of pipe, you end up with more joints, which means even more supports. continued on page 114

Most brands require you to support horizontal pipe every pipe length, or about every six feet, and vertical pipe every 10 feet or so. Furthermore, you also need locking bands at each joint.

WATCH THE SLOPE Condensing appliances generate one gallon of condensate per hour per 100,000 BTUs. A pitched system ensures that condensate does not build up inside the vent system. Pooled condensate can create back pressure, which can cause the heating appliance to shut down.

Polypropylene does require a greater slope than other vent systems, but that is because it is a gasketed system.

The additional slope ensures that acidic condensates do not come in contact with the gasket materials.

While PP venting is comparable in price to CPVC 636, once you add in the extra pieces it can start getting a little more expensive. In my experience in wholesale, the PP pipe itself is cheaper but the fittings, together with locking bands and supports, come to slightly more.

These prices can vary by region, but look into the â&#x20AC;&#x153;package priceâ&#x20AC;? before you decide what your costs are â&#x20AC;&#x201C; you might be used to CPVC, where the fittings are inexpensive, and where AIM FOR FEWER CUTS you mainly have to worry about your straight vent Components should be selected to minimize length to work up a price. cutting.

venting aren't universally approved by every boiler manufacturer. And polypropylene venting isn't as standard as PVC, so vent materials from different brands of PP pipe cannot be interchanged. These differences also mean that a manufacturer must certify their boiler, furnace or water heater with each manufacturer of PP, meaning that a contractor can't just â&#x20AC;&#x153;vent with PPâ&#x20AC;? unless they look up whether the boiler manufacturer approves that type of PP.

TEMPERING VALVES:

A NECESSITY FOR ANY SYSTEM

n the name of safer temperatures at the tap and shower, there’s been a push to reduce domestic water temperatures from previously-adopted standards. Though lower water temperatures can help to decrease scald risks, changes to storage and delivery temperatures can lead to other problems, ranging from decreased energy efficiency to Legionella bacteria exposure.

I

THE THREAT OF SCALDS In just six seconds, 60°C (140°F) water can turn healthy skin into excruciating, third-degree burns. For infants and the elderly, escaping exposure isn’t as simple as quickly jumping out of the shower or turning off the faucet. Even in perfect health, the skin trauma that scald induces can send anyone into a seizure, and with prolonged exposure an increased likelihood of serious or lethal consequences.

The severity of a scald incident depends on two factors, water temperature and duration of exposure. Burns from 1st to 4th degree are entirely possible, resulting in injuries ranging from that resembling sunburn, to catastrophes that literally cook flesh. Obviously, serious legal implications exist.

At single-family residences, those implicated may be the plumbing or mechanical contractor and the water heater manufacturer. For a commercial installation, the building owner, maintenance department and plumbing engineer may be pulled into the fray.

Scalding is not simply a matter of temperature only. Third degree burns can occur in one second at 70°C, or in 30 seconds at 55°C. The numbers vary depending on a variety of factors, including the area of exposure and age of the victim.

Obviously, any water heating device set to produce water above 49°C presents an immediate scald threat, but other factors contribute to the danger. Regardless of whether or not set at a safe temperature, inaccuracies or defects in a thermostat could cause water to be stored at a higher temperature, and even at a safe storage temperature, the phenomenon of layering or stacking can cause temporarily unsafe water delivery temperatures in an unprotected system.

Layering is a condition where – because of laminar flow – the hottest water rises to the top of a storage tank after a water draw is completed. The next draw can temporarily produce water at a higher than designed temperature. continued on page 120

PLUMBING continued from page 118

Simplicity is not the answer The simplest solution is almost never the best option to solving a problem, and assisting in scald prevention is no exception. Turning the water temperature back to 49°C will reduce the likelihood of scalding incidents, but can lead to numerous other problems.

Contrary to popular belief, turning down water temperature can increase the amount of energy consumed. More energy dollars are used because larger volumes of temperate water are needed to achieve the same comfort levels when bathing.

The BTU storage capacity is significantly reduced when the temperature is dropped from 70°C to 49°C. This increases the number of gallons of heated water needed to deliver 40°C to the shower head, since the tempered water will be a blend of cold supply water and the stored heated water, and it takes less 70°C heated water than 49°C water to temper the same volume for delivery at a tap or showerhead.

Decreased energy efficiency and BTU capacity are an inconvenience, but another consequence of turning back a water heater can prove fatal. Parts of Canada are known for the presence of Legionella bacteria in ground water, and reducing tank storage temperatures is flirting with disaster.

LEGIONELLA GROWTH Legionella is the bacteria responsible for Legionnaire’s Disease, an acute bacterial infection of the lower respiratory tract. At the levels found in naturally occurring sources, it typically does not pose a threat to public health. But when the bacterium enters a domestic water system it can find an ideal host environment of warm water temperatures (40 to 57°C). Under these conditions Legionella can rapidly colonize, forming higher concentrations that can lead to serious illness or death when atomized and inhaled – precisely what happens during a luxurious shower.

Even chlorine, the venerable bactericide, isn't effective against legionella, not even at concentrations much higher that we could safely consume. The simplest method available for maintaining bacteria-free hot water is to elevate its temperature in the water heater above 60°C and keep it there.

At 60°C, Legionella are killed within 32 minutes; at 66ºC, free roaming Legionella die within two minutes.

flushed or an appliance is turned on.

While Type P valves provide an excellent way to compensate for pressure fluctuations within a plumbing system, they cannot make adjustments for sudden, or gradual, changes in supply temperature. If hot water supply line temperature unexpectedly increases to a dangerous level while inlet water pressure remains constant, the pressure-balancing valve will continue to pass water but at a dramatically increased temperature.

These valves require seasonal adjustments of the limit stop, which is especially important in regions where extreme weather conditions dramatically affect temperature from water sources such as lakes and rivers.

Thermostatic tempering valves (Type T) compensate for fluctuations in temperature. Type T valves are designed to mix hot and cold water as well, delivering blended water at a constant, selected temperature.

The key advantage these devices have over Type P valves is that they have a temperature-sensing device. There’s no need to adjust the limit stop from season to season. The valve makes the temperature correction automatically to maintain the high limit set point.

Combination valves (Type T/P) meet the most stringent performance requirements for both temperature and pressure changes. They allow water to be generated or stored at higher temperatures and be delivered at safe temperatures to the user. They, too, require no seasonal adjustment of the limit stop.

Models are available for use at the source or point-ofuse for residential, commercial and industrial applications. Check local codes to determine whether the valves can be used as a secondary safety with a tempering valve at the source, or as the primary safety device, allowing water to circulate at higher temperatures.

ADVANCED APPLICATIONS OF PRIMARY-SECONDARYTERTIARY PUMPING T ertiary implies a three-level system, which is exactly what a designer might need to turn to in order to solve a problem that may be encountered in large systems.

ADD-A-LOOP To add a tertiary loop, a crossover bridge is added from the secondary supply to the return. This is then used as a site for a new common pipe, making the secondary loop and the new building loop independent of each other.

A new tertiary or building pump provides for the building’s head loss at design flow. If the existing secondary pump can provide enough flow to the new common pipe’s first tee, the building pump then can force the water through the building and return it to the second tee, where the secondary pump then can return it to the source loop.

In this way, the new building can be added without major change to the existing secondary pump. For this solution to be successful, the source equipment must have enough capacity to serve the new building.

124

M e c h a n i c a l

Suppose that, to meet the source manufacturer’s constant flow requirement, a primary-secondary system has been installed using a primary loop with a variable flow secondary loop to provide a means for controlling the heat transfer terminals at part load.

A low-pressure drop pipe common to both circuits can make the two loops hydraulically independent of each other. Flow in either loop has no effect on flow in the other.

Now, suppose that the two-pipe, direct-return secondary loop was designed for a given set of building loads, and the difference in pressure from the supply to the return is just adequate to serve the farthest building of the secondary loop.

What if the property owner decides to construct a new building at the end of the secondary loop, and the existing secondary pump impeller diameter cannot be increased enough to supply the increased head and flow required by this new building?

One option would be to add a tertiary loop.

B u s i n e s s

BENEFITTING LARGE PLANT SYSTEMS Building owners in large central plant systems can realize significant advantages by using primary-secondary-tertiary pumping systems. These systems provide the correct flow at the highest temperature to allow their building systems to cool and dehumidify the air.

Other advantages include decreased secondary pump operating costs and improved chiller operation.

Some additional advantages are not as obvious. Suppose a large chilled water plant has several customer buildings with different cooling and supply temperature requirements. If flow meters are installed, the central plant can calculate the actual amount of refrigeration each building is using, which can be the basis for billing or allocating costs. Controlling the chilled water flow to each building also allows for establishing priority among all chilled water users.

• A d d a l o o p • A r e lo o p s r eally in d ep en d en t ?

BLENDING: Benefits and challenges It is possible to control the blending process at the common pipe connection between the distribution (secondary) loop and the building (tertiary) loop by using a controller that measures and reacts to three important temperatures. To maintain an accurate temperature at T2, a bypass with a circuit setter is required around the control valve to provide a small flow, even when the control valve is throttled.

This controller must be carefully programmed to establish some priorities in determining the valve’s position and the amount of recirculation that occurs. The first of these priorities is the blended supply temperature going to the building coils.

BLENDING at the load loop Let's assume a system is supplying chilled water to existing building coils that require 45°F (7.2°C) water, but the coils in the new building were selected to provide adequate heat transfer at slightly higher temperature, say 47°F (8.3°C). A two-way modulating valve in the tertiary crossover bridge could reduce the supply flow with respect to the building flow provided by the tertiary pump. As discussed before, this would force mixing at the first tee, raising the building supply temperature to the desired 47°F, while reducing the flow provided by the secondary pump and lowering its operating cost.

Closing the valve in the secondary crossover bridge reduces the secondary flow with respect to the tertiary flow existing at that moment. This reduction forces blending of return water with supply water and decreases the secondary pump’s energy costs.

By recirculating the water, the return temperature at the chiller could be increased as well, improving chiller performance. Of course there are limits to the amount of recirculation the new building can handle.

In a hot water system, a substantial amount of blending could occur, resulting in considerable secondary flow and pumping cost decreases.

If the water to the building is too warm, the coils can't dehumidify the air properly, and that's not acceptable. Thoughtful application of primary secondary pumping principles in the hydronic system can solve problems by providing increased flexibility at low cost, and perhaps even reducing operating costs.

Chilled water systems require more careful control. With chilled water coils, excessive blending causes the supply temperature to the coils to rise above the dew point of the air passing over the coil; thus, the coil can no longer dehumidify the air.

Are the loops really INDEPENDENT? Although primary-secondary-tertiary pumping systems can provide hydraulic and thermal independence among the three loops, the loops aren’t absolutely independent in all respects.

Therefore, in a chilled water system the device controlling the valve in the secondary crossover must recognize that limitation and keep the valve open wide enough to avoid the problem.

For example, all the loops share the same water. If one loop is designed for a glycol-water antifreeze mixture and another loop is filled with plain water, the mixing that occurs in normal operation eventually distributes very dilute glycol throughout the system.

Thus, the building needing the antifreeze protection doesn’t receive it. Suppose a high-rise building is adjacent to a low-rise building. Static head from the high rise is imposed throughout the system, so the low-rise building’s components must be selected to withstand the high static pressure as well as the pump’s dynamic pressure.

If a designer wants to achieve independence regarding system fluid and static pressure, they must install a heat exchanger between the secondary and tertiary loops.

THERMAL ENERGY TRANSFER

for Commercial Building Efficiency olar thermal, wind, biomass and biogas, hydrogen, photovoltaic, and geothermal technology; all are now among the renewable energy sources being developed at a greater pace than anticipated just a few years ago. Related to geothermal is one of the fastest growing trends in the commercial building industry: the use of water source heat pumps, or water-loop heating and cooling systems.

S

Water-loop technology has been around for decades, though now, pushed by rising energy costs and such building rating programs as LEED, interest in the technology is gaining rapidly. The water-loop process is basically thermal energy transfer from one part of the building to another.

PUSHING EFFICIENCY The newest generation of water source heat pump heating and cooling technology for large buildings has pushed operational efficiencies into the 500 to 600 per cent range. For every unit of energy used to operate the equipment, the system delivers five to six units of energy in return.

That’s a smart use of energy.

Water-source heat pumps move heat very efficiently. More efficient models on the market will extract five kilowatt-hours of heat from the water loop for every one kilowatt-hour of electricity used to power the compressor and fan, delivering all six kilowatt-hours as heat into the air. This 6:1 ratio, the COP (Coefficient of Performance), can be equated to a 600 per cent efficiency level.

THERMAL ENERGY T R A N S F E R Thermal energy transfer (TET) systems provide highly efficient zone-controlled heating and cooling throughout a building by circulating water in a closed piping loop to move and exchange thermal energy. The system uses many separate heat pumps, connected by closed-system water loops to transfer thermal energy.

Individual heat pumps add or remove heat from the air within each zone as required to meet its unique heating or cooling load. During zone heating, they extract needed heat (thermal energy) from the common water loop. During zone cooling, heat is rejected into the water loop where it can then be shared with all other heat pumps throughout the building. It’s in this way that rejected heat – which can be vented to the outdoors in more traditional HVAC systems – is fully utilized before any new energy source is used to heat or cool the building.

THE HEAT PUMPING CONCEPT

SOURCES OF THERMAL ENERGY All buildings contain year-round sources of thermal energy, or internal heat gains, that can be recovered and recycled by a thermal energy transfer system.

Lighting - The electrical energy used for lighting in most structures varies from 1 to 4 Watts per square foot (11 to 13 Watts per square metre).

Water-source heat pumps use a simple vapour compression refrigerant circuit to efficiently provide zone heating or cooling.

During the cooling mode, heat is extracted from the air and rejected into the water loop. During heating mode, the process is reversed, with heat being extracted from the water loop and rejected into the air. Thus, thermal energy is transferred, or “pumped” between the air and the water loop, in either direction, on demand.

People - We emit thermal energy ranging from 300 to 500 BTUs per hour, depending upon our activity.

Equipment - The energy consumed by such equipment as computers, printers, copiers, pumps and motors is emitted as heat.

Solar gain - Perimeter zones with large glazed areas may require daytime cooling even during cold weather.

WHY WATER?

In a word: efficiency. Water is the most efficient way to move thermal energy. A two-inch water pipe can carry the same amount of cooling as a 24-inch air duct, requiring up to 90% less transport energy in the process and taking up far less space.

PUTTING IT TO USE Cast-off thermal energy within the building envelope recovered in the water loop of a water-source heat pump system can be used for most purposes that require heat.

Space heating - Water-source heat pumps in zones that require heating will extract thermal energy from the water loop.

Water heating - Water-to-water heat pumps can be equipped to extract thermal energy from the water loop to heat domestic hot water, swimming pools and spas, or to serve hydronic loads, such as radiant heat or snowmelt systems.

Ventilation - Dedicated “outside air” heat pumps extract thermal energy from the water loop to heat outside air used for ventilation.

DEPLOYING THE

VARYING LOADS

BENEFIT FROM EACH OTHER A typical building has a perimeter with outside exposure that is directly affected by variable outdoor weather conditions and a core without outside exposure that is virtually unaffected by the weather.

In order to understand the energy sharing benefits of a water-source heat pump system, the interaction of the loads in the core and perimeter zones must

be studied throughout the year during occupied periods, with internal gains, and unoccupied periods with temperature setback/setup and little or no internal gains.

The following are the main energy consuming operating modes of an office building in a temperate climate: Summer, occupied: Typically, all zones require cooling and are rejecting heat into the water loop.

The heat rejector maintains the maximum water loop temperature according to a predetermined set-point (fixed or outdoor reset). The boiler is off.

Winter warm-up: During recovery from night setback, most zones will require heating and will be extracting heat from the water loop. The boiler maintains the minimum water loop temperature according to a predetermined set-point. The heat rejector is off. The warm-up period is typically one hour or less per day.

Winter, occupied: Because of internal heat gain, most core zones require cooling. Most perimeter zones will require heating. Because heat is being simultaneously rejected into and extracted from the water loop, both the boiler and the heat rejector will remain in the “off” mode much of the time. And this is the essence of thermal energy transfer: the inherent sharing of energy within the water loop minimizes boiler and heat rejector operation and provides maximum system efficiency.

TECHNOLOGY

Water-loop heat pump systems combine water-source heat pumps on a common piping loop with a heat rejector and boiler, which are used to maintain the circulating water temperature within a controlled range, typically from 60°F to 95°F. The most common heat rejectors are open cooling towers with isolating heat exchangers, closed-circuit evaporative coolers, or dry coolers.

Each zone heat pump uses the water loop to provide heating or cooling at any time, during or after hours, regardless of the operating mode of the other heat pumps. This is accomplished without the duplicate operation of heating or cooling systems.

BRINGING WATER CONSERVATION TO THE

DESIGN TABLE s vice-president of the National Kitchen & Bath Association (NKBA), an industry association with members from Canada and the U.S., and the owner of a custom kitchen and bathroom shop, John Petrie is often called upon to share his knowledge and experience about kitchen and bathroom renovations.

A

With more than 25 years of experience in the industry, and certified as a Master Kitchen and Bath Designer, he is also a passionate supporter of water conservation in his designs.

A big part of that is the fact that early attempts at water conservation technologies simply didn’t go over very well. Consumers got frustrated and tried to bypass regulations, or lost interest.

John Petrie, Vice-president NKBA

We spoke to John to get his thoughts on what’s new in bathroom design and water conservation techniques and practices.

What can the industry do to help promote good water usage practices and technologies?

At a time when water shortage and cost-savings are a big consumer topic, understanding water usage and water-wise products, and applying this knowledge is part of doing your job skillfully. It's also a significant part of marketing yourself in the kitchen and bath industry.

Not every customer is thinking about water conversation when planning their bathroom needs, so I believe it’s up the industry to educate them. If they don’t ask about it, then I make it my job to bring up the topic and direct them to what’s important.

Why aren’t a lot of consumers on-board with water conservation when designing their bathrooms?

0 4 . 1 2

In the early 1990s, for example, we had the first push for 3.5 gallon toilets to be replaced by 1.6 gallon lowflows in an attempt to conserve water. The problem was they didn’t work. People often had to flush them two or three times to evacuate the waste. The U.S. government banned 3.5 gallon toilets before Canada did, and I knew people who lived close to the Canadian border who would drive up there to buy what the size they wanted since there weren’t restrictions there at the time. That’s changed now. continued on page 134

So what’s the latest on dual-flush and low-flow toilets?

When I talk to customers, their first and foremost concern tends to be style and comfort. I’m the one who brings up the water conservation part and dual and low-flush toilets.

Since 1995, there has been considerable testing done through the Environmental Protection Agency’s (EPA’s) WaterSense program. The toilets we see today have been tested to meet certain requirements for evacuating waste in a single flush. In fact we have been able to get from a 1.6 gallon to a 1.28 gallon true water conservation or high-efficiency toilet.

What we can do today with dual-flush toilets is phenomenal. And it doesn’t have to mean big dollars.

You can easily get a dual-flush high-efficiency toilet for a comparable price to standard low-flow.

Is it difficult to get these newer water conservation technologies?

Everything is readily available today – although that wasn’t the case a few years ago. Most major manufacturers, whether it’s Kohler, Eljer, Niagara, American Standard or others, they already have dual and low-flush toilets, aerators, faucets and showerheads that meet low-flow and restricted-flow requirements.

What are some upcoming trends relating to water conservation and design?

Outside the home, grey water systems are becoming more and more popular especially in drought-plagued areas. With those, you can get second and third uses out of your water.

Another trend is centralized plumbing. That’s easy to do in a newly built home. If you can centralize your hot water heater and use shorter runs you can do quite a bit to improve water usage. Recirculating pumps on hot water heaters are another thing people are starting to use.

In instances where you can’t relocate the hot water heater any closer, we often put an instant or point-ofuse hot water heater in the bathroom itself to save energy and water.

How strong a marketing draw is water conservation?

I wish I could say that water conservation is a topic that customers would initiate with me, but I’m still the one to bring it up with them in the design phase. Right now I think water conservation is a strong marketing angle, as long as you can talk intelligently about it and deliver the products that fulfill the promises.

WHAT ARE THE LATEST PLUMBING RELATED HOME RENOVATION AND UPGRADE TRENDS IN BATHROOMS? The master bathroom is getting bigger and becoming a retreat. That’s because it’s the area where you start your day and unwind in the evening.

The biggest trend we’re seeing today is larger walkin showers. Some are generous enough in size that there is no door.

ADDING AIR AT THE AERATOR “Aerators have been redesigned – make no doubt about it. Years ago when we put showers in that used water restrictors, we’d get calls that they couldn’t get enough water. A lot of people simple unscrewed the unit and plucked out the restrictor.

Another newer trend is steam showers. There the doors fully enclose the shower area and a generator in the basement or closet is used to pump in steam.

In my corner of the world we’re doing a lot of rain showers with separate handheld body sprays. But we’re not doing the “car wash” type of shower so much these days.

The tubs that we were putting in like crazy in the ’80s and ’90s are being taken out. That being said, tubs are still a must if you have multiple bathrooms.

It would be wrong of us to not suggest they keep one in. A tub helps the resale value of the home, especially if the buyer is a new family with kids. If they want to get rid of it in the master bathroom that’s fine, as long as they have one in another for bathing kids, or for people that can’t stand in the shower.

Good at both ends of the rink Paul Henderson might be best known for that brief moment in time on a rink across the ocean, but he was one of the top two-way players in the game, potting 38 goals in the 1971-72 campaign with the Toronto Maple Leafs. “That was one of the reasons I was chosen for the team, and I was always a good defensive player,” he recalls. “I had speed too, and took pride in the fact that I was a good defensive hockey player.”

Cover Story

By Adam Freill

E

veryone has a seminal moment or two in their lives. For some, the image of Neil Armstrong setting foot on the moon will forever be etched in their minds. For American hockey fans, the Miracle on Ice from the Olympics in Lake Placid, N.Y., might be where they turn to for inspiration. But for a Canadian kid, nothing ranks higher than “The goal heard around the world.”

About Paul Paul Henderson is a member of Canada's Sports Hall of Fame, and was a member of Team Canada ’72, which was honoured at the Hockey Hall of Fame as the greatest team of the 20th Century. He has co-authored several books, and has just finished writing his autobiography. He is married to Eleanor, his high school sweetheart, and they have three married daughters and seven grandchildren.

Paul Henderson was not a shoe-in to make the 1972 team that took on Russia’s best in the Summit Series. Team Canada was made up of the top scorers and defensemen from the NHL, and while Henderson was a solid NHL player, earning a spot on the team meant full effort at all times, in practice and come game time.

Paul would not be held back though.

With the series on the line, he scored the game winning goals in games six and seven in the eight-game series, before etching his name permanently in the annals of hockey history with the series-winning goal in the eighth game, protecting Canada’s reputation as the world’s powerhouse of hockey.

“I was on the bench, and I stood up and started yelling at Pete Mahovlich to come off the ice. I just felt I had to get

out there,” explained Henderson, during a recent chat in advance of his upcoming speaking engagement at CMX/CIPHEX in Toronto. “I fell into the boards. So I get up, and bang, right there, [Phil] Esposito whacked it at Tretiak, and I got the rebound and man, it was over before I knew it.”

Not completely over. The celebration has been on for almost 40 years, something that even surprises the man of the moment. “I knew it was a big goal – we won the series – but the impact, staying around for 40 years, no one in 100 years would have ever thought of that.”

The best and worst of the Original Six The years of the Original Six represent what many suggest is the most classic era of hockey. Jobs were scarce, and fans were fierce in their loyalty, and every arena had its own style and atmosphere.

“I hated going to Madison Square Gardens.

They had so many shows going on there that the ice was terrible. The puck would bounce around. Thank goodness I didn’t play for New York. They had the worst ice,” says Henderson.

But does he ever get tired of talking about it? “Never, because there is no downside to it. That ’72 moment just resonates with Canadians.”

Paul Henderson will be speaking during breakfast at the CMX/CIPHEX show in Toronto on Saturday, March 24.

Seating is limited, so visit www.cmxciphexshow.com to register.

“When I broke into the league, there were only six teams, and every arena was like a shrine,” he recalls. “I remember Chicago Stadium, the organ would go and the place would just rock; the Boston Garden, was a dump, the dressing rooms were the worst. A pee wee team wouldn’t even dress in them today. I’m talking nails on the wall to hang your clothes on. But I think I would have paid them to let me play the game back then.”

Reflecting with Paul How early in life did you know that you had a shot at making it in the Pros?

When I was in Grade 5, I started practicing my autograph. I wanted to be an NHL hockey player. My last year of junior, I scored 49 goals. By that time I knew I could play in the NHL. I was fast, and I had a good shot. And I made the NHL in my first year.

What lessons from sport have you brought into life beyond hockey?

Everything nice has a price, and the longer you wait to pay for it, the more expensive it is going to be. If you are going to get anywhere in life, you have to work on it hard.

The secret is to be a team player. If you go out there and try to be selfish, it just never works as well.

On Team Canada in ’72, I never once thought about going out there and scoring a winning goal to be the hero of the series. We went out there and had a job to do. It doesn’t matter what you do, but go out there and do it to the best of your ability. It usually turns out pretty well.

Who were your hockey heroes?

A guy like Jean Beliveau is just a classy individual. I would say more players probably looked to Beliveau. He played the game with class. He was a tremendous competitor, but he conducted himself with class, off the ice as well. He set the standard.

Growing up, I was a Red Wing fan, and my dad was a huge fan of Gordie Howe.

Memories of ‘72 People are always approaching Paul Henderson with their stories about where they were when he scored that fateful goal. For Mechanical Business art director Dave Morton, his fondest memories of the goal actually come from the days after the series, when his neighbour (Paul Henderson) returned from Russia.

“After he scored those goals, he was the nicest man to everyone in the neighbourhood, signing anything you would give him to sign,” recalls Morton. “I had him sign my stick and then, like any six-year-old who didn’t know better, I just went back out and played street hockey with it.”

Apartment retofit challenge

Jeff House is an experienced industry professional and hydronics trainer. He handles the sales territory from the Niagara region to the Greater Toronto Area for Jess-Don Dunford, a manufacturers’ rep in Ontario. He can be reached at jhouse@jessdondunford.com.

An old cast iron boiler was removed and replaced with a high-efficiency modulating condensing boiler. The water heater was changed to an indirect water heater off the new boiler.

The instructions were simple, join the return to the supply and add the boiler using closely spaced Ts. Pipe the indirect directly, using its own circulator matched to the boiler requirements and let the boiler control all three pumps.

In no time there are multiple calls with not enough hot water. Everything seems to be working fine, but there is a definate shortage of DHW.

After going to the site, the boiler manufacturer’s rep makes the following suggestions:

3. The old boiler piping was 2-1/2” but the new boiler piping could have been done in: A) 1-1/4” just like the boiler fittings, provided that the delta T is 30°F. B) 1-1/2” would be right with a 20°F delta T. C) 2” would work best.

D) All anwers are correct.

1. Although the boiler is working and there is heat in the building, the piping should be: A) True primary/secondary.

B) The piping is fine leave it alone.

C) The pumps acting in series it will overcome the high head required to overcome the boiler and the old system.

D) This would have been a perfect place to use a low-loss header.

4. A proper heat loss of the building showed that 124,760 BTUH of heat are needed, but the old boiler was fired at 225,000 BTUH. You selected the 210,000 BTUH model because it has higher efficiency than the old boiler, so they should be about the same.

2. Further inspection of the indirect shows the heat exchanger connections to be 3/4” and the tank is 80 gallons. The manufacturer literture says with the 210,000 BTUH input boiler you should get plenty of hot water. You do a little math and determine: A) No problem.

B) You would need to get about a 100°F delta T through the heat exchanger to produce the claims of the manufacturer.

C) You should have piped the indirect with 2” piping.

D) The indirect pump is the wrong size.

A) It was fine to go with the smaller boiler, right?

B) You kept it a little high because now you were going to do the DHW as well.

C) It is a modulating boiler, so it will get to the right size any way.

D) You always oversize a little, the last thing you want is the customer to complain that he is cold or does not have enough hot water.

E) The math shows you could have selected a 150,000 BTUH model and, with a proper indirect, would still have plenty of hot water.

Line with David Cooke

Don’t get taken to the cleaners

Costly, but not uncommon In my years dealing with contractors, I have heard some horrible stories; shocking not only because of the damage done, but by the nerve of the perpetrators.

Like the mousy bookkeeper who fleeced a roofing contractor to the tune of thousands of dollars over five years. In another instance, an electrical distributor’s warehouse shipper, while being paid for overtime on a Saturday, offloaded extra equipment to the firm’s customers in exchange for cash.

Not every company has the misfortune of falling victim, but those that do pay a penalty that’s felt by everyone else in the firm.

After years in the HVAC industry, David Cooke is now a partner with Qualified Financial’s Wealth Strategies Group.

He can be reached at david@wsgcanada.com.

If you’ve taken the time to read my articles, you know I rarely venture from the world of personal and business finances into the world of management, but a recent phone call reminded me of what continues to be a plague for small business – something that can ruin the prospects for success.

It’s not taxes. It’s not the cost of fuel or wages. And it’s not government bureaucracy.

Believe it or not, it’s fraud. And worse; employee fraud.

So what are we talking about? Shockingly, it’s not hightech computer fraud or elaborate embezzlement schemes. We are talking simple fleecing here.

Research has shown that a high percentage of theft in retail stores is either performed or facilitated by company employees. In the United States, a shocking number of robberies of fast food outlets turn out to be conducted by store employees, off shift. So, we know the problem exists, but what is the cost?

For a small business operator, the short-term and longterm costs can be staggering. Think about it. If an employee defrauds your company, the value of that fraud and any growth that may come from it is lost forever.

Based on investment strategies, it is not out of line to reason that a simple fraud of $50,000 could ultimately cause a loss to the owner or the company somewhere in the vicinity of $250,000 as the lost investment opportunities compound over the span of 20 or so years.

Would your retirement suffer if you lost this?

Short term, the company could need to liquidate other assets, or scramble for additional loans. Worse, the full extent of the damage may never be known.

And don’t fool yourself into thinking that discovery equals resolution. Even once a fraud is uncovered, it is almost impossible for a company owner to recover funds lost. This can only mean a loss to you as owner, not to mention the grief and sense of betrayal.

So before I have you suspecting everyone working for you, relax. This is not about imagining the worst in people, in fact, it is quite the opposite. It is about creating an environment of accountability and control within your business, and no decent and honest person is going to take issue with that.

The good news is, there’s never been a better time to implement controls to prevent or detect fraudulent activity.

Prevention and early detection of fraudulent activity within a company may have profound impacts on a company owner’s long term retirement wealth. It pays to think and implement controls in your company now, and that’s the bottom line…..

Controls for contracting firms For contractors, having controls in place translates into tight inventory control over equipment and supplies, as well as appropriate tracking of time and mileage for field trades.

It means internal financial controls, and reconciling on a regular basis.

I think you’ll agree a red flag after one or two months sure beats discovering a problem 10 months later. If you use an outside accounting firm, ask about procedures you can use to track financial activity within your company.

Be part of the future

in Australia

nlike many other market sectors, the plumbing world is generally conservative in nature. This means the industry pretty much keeps to itself. It’s not out-there in terms of telling the world about the good work it does, or the exciting technical solutions it continues to uncover.

U

New technologies are often quietly introduced to the market without any tickertape parade or rock stars touting how the new product is going to change mankind and be a positive influence on society. Maybe that’s because plumbing technologies are continually being refined, rather than being completely reinvented.

Constant and consistent change can also make it difficult to forecast the direction the industry is taking. There is no crystal ball or think-tank, and unlike the computer sector, for example, the plumbing market is not driven by the need for more speed, more capacity, etc. If anything, this industry is trying to slow things down: less water flow and more harvesting, particularly as weather patterns appear to be producing more heavy rain events.

While new plumbing technology may not be feted the way a new iPhone is, there’s no reason why you shouldn’t go out looking for it. And who knows, it might be one of your very discussions at an industry event that can help shape the future of the industry.

The 3rd International Emerging Technology Symposium is scheduled to take place in Washington, D.C., on the 1st and 2nd of May. Hosted by IAPMO and the World Plumbing Council, you are welcome to take part in this important two-day event that will draw delegates from all over the globe.

I’ll be talking about some of the global research on phosphorous that I began to outline in these pages a few columns back. One way to sustain this necessary mineral is through the collecting of urine. Urine contains a significant amount of phosphorous, but it is flushed down waste systems daily.

In Australia, the Institute for Sustainable Futures is conducting field trials in different community situations to better understand the practical – as well as social – issues involved in separating and collecting urine and repurposing it.

Yellow Plumbing may well be one of this industry’s next great business opportunities, driven by new technologies and a basic want. Perhaps it is the ultimate way of answering nature’s call. See you in Washington.

218

A HOP, SKIP AND A JUMP For many of you, the venue for the International Emerging Technology Symposium is just down the road. I’m going to make the effort to be there and if it’s any comfort, I’m flying 10,000 miles across the Pacific to do so.

I’ve got a gig on one of the days and although I don’t expect you to make the trip down just to see me, my subject matter (Yellow Plumbing) may be a good indication of the variety of plumbing topics this symposium will cover. For more information about the conference, visit www.worldplumbing.org or www.iapmo.org.

Q: Why can't they make a drain with overflow that works?

A: We did! Fill&Drain™ by OS&B™ does work….

=

=

Problem: The overflowing bathtub water in Room 712 ends up in Room 405.

Solution: The new 360 Series Fill&Drain™ Waste & Overflow System by OS&B™.

Our innovative new Fill&Drain™ Waste & Overflow combines the functionality and convenience of Filling and Draining the bathtub through one integral unit. We are able to Drain away what we Fill even with the drain in the closed position therefore eliminating overflowed tubs (based on our 1/2” Inlet model). Fill&Drain™ with its patented backflow prevention technology also eliminates the need to install an external Atmospheric Air Vent.

Save costly repairs and eliminate mould from an overflowed bathtub by using the combined functionality of Fill&Drain™. We also eliminate the need for a traditional tub filler. If a tub filler with diverter spout is being eliminated, installation requires a Positive Action Diverter Valve located on the T&S Valve or installed separately.
