While researching labour and staffing issues I came across an interesting web site run by the U.S. Department of Labor. A hiring tool kit (americasheroesatwork.gov/forEmployers/HiringToolkit) offered there appeared to be a valuable resource and I was curious as to whether the Canadian government had something similar. A call to Veterans Affairs Canada (VAC) revealed that, while there is not one specific initiative like the employer tool kit mentioned above, there are programs at various levels that provide assistance and encouragement for employers to hire veterans. These include: »» VAC’s Career Transition Services (CTS), provided through Right Management (a national contractor), to eligible Canadian Forces (CF) members and veterans to help them prepare, and eventually search for, civilian employment. Right Management also connects employers to veterans via the CTS Job Bank and Talent Profile Bank. »» VAC’s Rehabilitation Program includes a vocational component provided by a national contractor, CanVet. In addition to preparing veterans for their job search, CanVet also conducts employer contact activities to encourage the hiring of veterans. »» As part of the services offered to CF members, Department of National Defence’s (DND) Transition Assistance Program (TAP) actively recruits prospective employers, in both the public and private sectors, to consider providing employment to job-ready CF members. Veterans Affairs identifies the following qualities and characteristics as those that make CF members valuable employees: transferable competencies and personal attributes; unmatched experience, technological expertise and on-going training; operational capacity; many have experience working in high pressure settings; they are located across the country; they have security clearances; and they often have the flexibility and willingness to relocate. Aside from Veterans Affairs, there are other organizations out there whose sole purpose is to place veterans in viable employment. Another is hirecanadianmilitary.com, a site not unlike Workpolis or Monster that was created by retired CF individuals to connect their "above the ordinary" skills, leadership and discipline with the right employer. In this industry we need “above the ordinary” but finding it can sometimes be a challenge. Perhaps this avenue will open up some possibilities for your company. <> Editor

Cool it!

The LOFlo Mixing Block (LMB) is the latest addition to our LoadMatch® System. It works as a complete injection mixing station, delivering the correct temperature – from low to high or high to low – at the terminal unit without aﬀecting the pipe size.

It’s a convenient way to maintain a typical Delta “T” without increasing pipe sizes. This new idea lowers both energy consumption plus initial material and installation costs. It also results in precise control of the room temperature. Cool.

The LMB provides only the ﬂow and the temperature of water needed to satisfy the zone load at any given time. TACO CANADA LTD. 8450 Lawson Road, Milton, ON L9T 0J8 Tel. 905-564-9422 Fax. 905-564-9436 www.ﬂoproteam.com

SEE THE LATEST HPAC e-newsletter @ hpacmag.com Bringing Inspectors Up To Speed The Canadian GeoExchange Coalition (CGC) and the Ontario Building Officials Association (OBOA) have entered into a Memorandum of Understanding (MOU) to train Ontario municipal inspectors and other building officials in inspection processes and building code issues around geothermal heat pump technology, and to partner generally. CGC originally developed its inspector course materials in cooperation with City of Calgary’s Development and Building Approvals office and has consulted on the materials nationally. “Regulators and policymakers are increasingly dealing with disjointed or inadequate regulations for geothermal, throughout the country,” remarked Ted Kantrowitz, CGC vice president. “Industry meanwhile finds great variation between inspectors, due mostly to varying levels of familiarity and comfort with our industry’s highly innovative, renewable energy technology. This partnership is intended to help strengthen municipal inspectors’ sophistication at the same time it improves the national quality program.” Working with CGC in 2010, OBOA trained approximately 25 inspectors at its training facility in Barrie, ON. The

instructor then accompanied inspectors on several site visits for practicum exercises. OBOA, using its own facilitators, is currently deploying training for municipal inspectors throughout the province. CGC's municipal tools, developed by a consortium of municipalities, include: a model inspection procedure, based on existing regulations; a municipal by-law template for regulating geoexchange; and a municipal policymaker guideline, with ranked steps to deal with geothermal systems. oboa.on.ca | geoexchange.ca

TECHNOLOGY TRANSFER AWARD GOES TO CANMETENERGY The CoolSolution approach to refrigeration in arenas and supermarkets, which has helped reduce GHG emissions by about 1.6 megatonnes a year, has saved approximately $15 million in annual energy costs and lowered operating costs by an estimated $40,000 to $100,000 per year. Those achievements have taken the Natural Resources Canada (NRCan) CanmetENERGY team from Varennes, QC, to the winners circle. The team received a 2010 Technology Transfer Award from the Federal Partners in Technology Transfer (FPTT) initiative for developing the CoolSolution program. Through partnerships with owners and managers of institutional and commercial buildings, energy providers, consulting engineers, refrigeration manufacturers and HVAC specialists, the team was successful in deploying energyefficient refrigeration and heating systems at more than 100 supermarkets and 100 rinks across the country. canmetenergy-canmetenergie.nrcan-rncan.gc.ca

and Environmental Report (BBEER). Available online, the report is based on the BOMA BESt (Building Environmental Standards) program for commercial real estate in Canada. The 2010 BBEER provides an overview of the energy and environmental performance of approximately 300 existing buildings, representing 92.3 million square feet, which were certified between June 2009 and June 2010 based on the BOMA BESt assessment, Levels 2 to 4. The report’s key findings indicate an increase in BOMA BESt scores showing that the program plays a significant role in improving building performance. The overall energy intensity average for BOMA BESt certified buildings is 31.85 equivalent kilowatt hour per square foot per year (ekWh/sq.ft./yr), which is lower than the national average of 36.65 ekWh/sq.ft./yr. The report also provides values by building size, age and region and identifies the percentage of buildings that have implemented retrofits, incorporated energy and water efficient features, and have strong environmental management practices and policies in place. bomabest.com

Mitsubishi Electric’s Zuba-Central is an ENERGY STAR-rated forced-air heat pump designed specifically for the Canadian market. Unlike traditional heat pumps which cannot operate when the outdoor temperature gets below 0°C, Zuba-Central offers 100% heating capacity at -15°C. Even when outdoor temperatures go down to -30°C, Zuba-Central can still function at peak efficiency with 75% capacity. Designed for Canada The secret behind such high-heating performance, even under extremely low outdoor temperatures, is our exclusive Hyper-Heat Inverter (H2i) technology. The H2i technology overcomes the shortfall of compressors overheating in cold temperatures for trying to maintain a stable discharge pressure. This gives Zuba-Central the power to maintain a high-heating capacity and achieve higher performances without being affected by the cold. Powerful Savings The Zuba-Central heat pump system can cut annual home heating and cooling costs by as much as 60% while slashing carbon emissions. Comparing heat pumps’ energy efficiency to other means of heating, even the most efficient gas furnaces only have COP of 0.95 and electric furnaces are 1.0. Not to mention the propane and oil furnaces that go further down on the list. Zuba-Central’s COP ranges from 1.4 to 3.19, depending on the outside temperature, and it actually gets more efficient as temperatures increase! In an estimated calculation for a typical 2,500 sq. ft. home in Vancouver, it would cost up to $2,967 for heating with electricity annually. Yet with Zuba-Central, the annual heating cost would be as low as $904, saving over $2000 a year! Although actual savings may vary depending on application and rates from different energy providers, the savings are significant. Quiet, Compact, and User-Friendly: It’s called Mitsubishi Electric Quality Zuba-Central’s outdoor unit runs as low as 52dB(A). With the outdoor unit measuring only 13 inches deep, you can have it installed virtually anywhere alongside the exterior wall without taking up much real estate. In addition, Zuba-Central now features a new touchscreen thermostat which ensures smoother installations and provides the homeowner with seamless state-ofthe-art controllability. It is our commitment to innovation, technology and service – we stand behind every product that bears the Mitsubishi Electric name.

Pay Now Or PAY Later Modeling downward heat losses – a last opportunity before a lost opportunity. BY ROBERT BEAN

found in Canada and provisioned for RSI increases where water levels are present within five metres (16.4 ft) of the slab base layer. However, such an international benchmark won’t reduce the domestic risk created with the latest edition of the National Building Code. It references CSA B214-07 Installation Code for Hydronic Heating Systems, which does not require manufactured insulation; rather it allows an equivalency based on the soil conductivity between the underside of the slab and top of the water table. This means that in jurisdictions enforcing the CSA B214, manufactured insulation will not be required if it can be shown that the soil provides a, “thermal resistance value equivalent to an RSI 0.9 m2•K/W (R5 h•ft2•°F/ Figure 1 Sample hourly FEA screen shots for transient foundation heat flows from a yearly simulation.

Furthermore, such a prescriptive clause 20

s many readers know, one of my pet peeves lies with under slab insulation, particularly as it relates to heated slabs. I, like a dog with a bone, will not let it go because slabs are permanent elements of the enclosure and are frequently placed without a thorough analysis of downward losses. In the case of residential buildings, the absence of such a review can forever penalize homeowners with operating costs of an unknown magnitude (see Note). In an ISO document currently being developed by global experts in radiant heating and cooling, there is to be a minimum requirement of RSI 2.0 m2•K/W (R value ≈ 12 h•ft2•°F/Btu) for heated slabs typical of climates

Figure 2 Sample FEA screen shots (on grade-left; below grade-right) in a side-by-side steady state comparison between an uninsulated (right) and insulated heated slab (left) for a specific set of conditions.

On Grade

presumes the contractor responsible for the insulation decision has extensive historical knowledge of the geotechnical conditions and has the skills to ascertain if the subsoil meets the requirements of the code. Demonstrating this knowledge and skill is not defined by the code. One does not have to be a professional architect or engineer to sign off on something with the potential for unintended consequences. To be clear, I am a big fan of the CSA B214 and reference it frequently, but having trained thousands of contractors, engineers and architects, I can say with certainty that only a few of those working in the residential sector will have a thorough understanding of what lurks five metres (16.4 ft) below the slab. I also know from experience that, driven by value engineering, what is stated as a minimum in code becomes maximum in practice. It has been said before but bears repeating -- the principles of heat and mass transfer through the enclosure apply to all six sides of the building. It remains a mystery

NOTE: Two recent cases: one in Ontario, Canada and another in New Mexico, U.S. dealing with uninsulated heated slabs having underperforming systems with excessively high and unsustainable fuel bills. In both cases the above grade enclosures exceeded local building code standards. Both homeowners purchased radiant systems because of their claimed energy efficiency. Message – in the absence of enclosure efficiency even efficient HVAC systems look like mutts.

BELOW Grade

to this author as to why there are minimum insulation requirements enforced for walls and roofs but under slab insulation in residential buildings remains at the discretion of “others” (exceptions to jurisdictions enforcing to the contrary). At polar extremes and of equal interest for commercial buildings, is the requirement in the Model National Energy Code for full insulation under all heated slabs in all climate zones. This applies regardless of whether a thorough analysis can show full interior insulation as unnecessary, particularly in large high performance buildings where fluid temperatures can be within 8C (15F) of space temperatures. For the record, this is not just a Canadian issue; there is little consistency on the North American continent between national, state and provincial codes when it comes to specifying under slab insulation. To bring some understanding to the topic, the following are the key influences for analyzing downward heat loss: 1. Soil characteristics including soil type, moisture content and density below and adjacent to slabs and transient characteristics of the “water table” including short- and long-term patterns. 2. Temperatures above and below grade; temperature desired for space conditions; temperatures in heating pipes, a function of the slab conductivity, surface flux, tube spacing and flooring characteristics. This includes tube patterns, i.e. warmest fluid versus coolest fluid in relation to edge. continued on page 22

“ ...driven by value engineering, what is stated as a minimum in code becomes maximum in practice. ” 3. Slab characteristics including flooring R values, thickness, conductivity and elevation in relation to grade and enclosure performance above and adjacent to the heated slab, including effects from solar gains. 4. Aspect ratio of building, that being either the width to length ratio or area to perimeter ratio, that is rectangular buildings versus square buildings. One residential slab on and below grade heat loss tool incorporating some of the items above is BASECALC, a finite-element (FEA) calculations tool offered at no cost by Natural Resources Canada's CanmetENERGY. Though the use of FEA for residential design is limited to a few enthusiasts, BASECALC has a friendly front end which makes it easy to use by everyone.

For a bit more flexibility, including the incorporation of heating pipes, one has to step into proprietary FEA programs. These can model steady state and transient conditions (Figure 1 and 2) using various combinations of foundations, radiant designs and soil conditions, but even these can become difficult to set up for unknown geologies, including non-homogenous soil conditions. Due to the uncertainty between simple and complex analysis under steady state and transient conditions, I am of the opinion in the absence of professional involvement, that all residential slabs should be insulated with a minimum R-8 type 2, 3 or 4 EPS/XPS insulation.

Interestingly, building owners who have properly insulated slabs never call me crying over excessive fuel bills. Unless you have figured out a way to insulate underneath a slab "later" or have powers greater than Mother Nature for controlling soil conductivities, insulate your slabs or hire a building science professional to evaluate your project. You may or may not need full insulation but when it comes to concrete and insulation you get one chance – as they say in retail – all sales are final. <>

Paradigm Shift In Technology

The basics of “Delta P” pumping in small hydronic systems. BY JOHN SIEGENTHALER

ntil recently, circulators used in smaller hydronic heating systems have undergone relatively minor changes. The vast majority of these circulators are cast-iron, wet-rotor, inline circulators with PSC (permanent split capacitor) motors, and two-bolt flanges. Over the last three decades, the motor size and amount of metal used in these circulators have slightly decreased as a result of value engineering. Most have also transitioned from single- to three-speed motors, which allows the installer to better match the circulator’s characteristic curve to that of the system. Finally, many of them now come with an internal check valve that eliminates the need for an external flow check valve. I

would categorize these changes as evolutionary rather than revolutionary. Circulator manufacturers have done a good job in creating a relatively low cost product that gets installed in a hot, wet, potentially corrosive environment, where it is expected to last at least 20 years, with zero maintenance. Can you think of another mechanical or electrical device in your house that could meet this same standard? The competitive nature of the market has resulted in small circulators becoming commodities. As such, no single manufacturer offers a competitively-priced product that is vastly superior in terms of technology, lifespan, or energy efficiency. Although I may have ruffled a few feathers with that last sentence, it is not a put down, just my observation. The fact that just about all these small circulators come with the same 6-3/8" face-to-face dimension between their two-bolt flanges, and are thus easily interchangeable, confirms their commodity status.

An exploded view of a small ECM powered circulator.

HPAC | MARCH 2011

About three years ago, a new type of small circulator appeared in the North American market. It was equipped with an ECM (electronically commutated motor), along with on-board electronics and intelligence to automatically regulate motor speed in response to operating conditions. Since then, additional circulators with similar characteristics have entered the North American market. By my count, there are now four manufacturers offering variable speed circulators with ECM motors in North America. Others are sure to follow. hpacmag.com

THE NEW KIDS IN TOWN

Although the current offerings differ as to how motor speed is controlled, as well as their “user interface,” they all represent a paradigm shift to a new level of technology. This article discusses the basics of how the majority of these “smart” circulators work and how they can be applied. ECM motor technology is based on a permanent magnet rotor in which very strong rare earth (neodymium) magnets are sealed into the rotor assembly. There are no windings

than PSC motors. This greatly reduces the possibility of a “stuck rotor” condition after prolonged shut down periods. Although variable speed circulators can be used for applications, such as boiler anti-condensation control and injection mixing, this article focuses on their use as heating (or cooling) distribution circulators. As such, they are ideal in systems using valve-based zoning. Such a system could use electrically operated zone valves, thermostatic radiator

“A properly controlled variable speed circulator can alleviate this undesirable increase in differential pressure.” within the rotor and no brushes between the rotor and stationary part of the motor. The operating concept of an ECM motor is straightforward. A microprocessor and associated solid-state switching circuitry control electrical current flow through the stator pole. This causes the magnetic polarity of each pole to change from north to south and vice versa, or remain off. The combined attraction and repulsion forces generated between the permanent magnet rotor and poles create a torque that causes the rotor to spin. The faster the stator poles change polarity, the faster the rotor spins. Electronically commutated motors are ideal when accurate speed control is needed. They are also significantly more efficient at converting electrical energy into mechanical energy compared to the permanent split capacitor (PSC) motors used in most current wet rotor circulators. ECMs also create approximately four times greater starting torque Figure 1 Relationship between the circulator pump curve and head loss curve.

valves, or even a combination of the two. Assume the system is operating at design conditions, with all zone valves open. Figure 1 shows the relationship between the circulator’s pump curve (shown in red), and the system’s head loss curve (shown in grey). Their intersection represents hydraulic equilibrium, where the circulator imparts head energy to the water at exactly the same rate that the piping system dissipates head energy from the water through friction. This intersection is called the design operating point of the system. If one or more of the zone valves closes, either fully or partially, the system’s head loss curve immediately becomes steeper, as shown by the blue curve in Figure 1. If a fixed speed circulator is used and no differential pressure bypass valve is installed, the operating point moves up the pump curve until it settles at the new operating point (shown in yellow). The movement of the operating point can be broken into two components: A move to the left and a move upward. The movement to the left is desirable because it represents a reduction in flow through the system. This is an intended consequence of closing, or partially closing a zone valve. The upward movement indicates an increase in differential pressure between the supply and return headers. This is undesirable because it causes flow in other operating zone circuits to increase and there is no need for this. In some systems the increased flow can even cause flow noise or erosion of metal pipe.

pressure. This process is depicted in Figure 2. It takes only a few seconds for the electronics in the variable speed circulator to detect a departure from its set delta P and respond with a speed change to cancel out the attempted change. This detection and speed correction is all done without need of any external sensors. If additional zones open or close, the same compensation procedure repeats itself. The constant delta P mode is ideal in systems where the majority of the head loss occurs within the individual zone circuits and thus only a small portion of the heat loss occurs through the headers and heat source. A cast iron boiler with generously sized headers supplying multiple zone circuits from the headers is a good example. Another is a system with generously sized headers that are connected to a heat source through a pair of closely spaced tees or a hydraulic separator. Examples of this piping are shown in Figure 3. Some small ECM-based circulators can also be set to operate in proportional differential pressure mode. This mode is intended for use with systems configured as twopipe direct return or two-pipe reverse return. An example of the latter is shown in Figure 4. In both two-pipe configurations, a significant portion of the system’s total head loss occurs in the supply and return mains. Proportional differential pressure control better compensates for this effect relative to constant differential pressure control. It reduces differential pressure HPAC | MARCH 2011

active at a given time. Both constant differential pressure control, and proportional differential pressure control eliminate the need for differential pressure bypass valves in the system. The savings associated with not having to install such a valve significantly reduces the incrementally higher cost of ECMbased circulators, especially in smaller systems.

Besides differential pressure control, ECM-based variable speed circulators can significantly reduce electrical energy use relative to that of standard PSC circulators. Each time the operating point moves left, down or both, the input wattage to the circulator’s motor decreases. The exact savings depends on the system and how many hours of partial flow the system experiences.

For the system represented, the flow rate was at or above 50 per cent of full design flow for about 1,080 hours per heating season and at or above 75 per cent flow for about 350 hours per heating season. Considering that the heating season represented consists of about 3,600 hours, this implies that flow is at or above 75 per cent of full design flow less than 10 per cent of the year. That is a good incentive to optimize circulator performance for partial load conditions. When this type of load pattern is the driver behind variable speed circulators operating on differential pressure control, electrical usage over a typical heating season is reduced to 60 to 80 per cent of that required by a fixed speed circulator with the same design flow and head characteristics. In many cases these savings will return the

The North American hydronics industry is just beginning to understand and apply ECM-based variable speed circulators. Like other innovative hydronic components, broad acceptance will take time as word spreads about successful applications and favourable economic returns. As the North American market is introduced to these products, European standards for even higher efficiency circulators have been established and are set to take effect by 2016. With time and demand, this technology could make it to our market. That demand will grow as people, such as those reading this article, see what this technology can do for them and their customers. If you have not tried one of the currently available ECMbased circulators in a smaller hydronic system application I encourage you to do so.

THE LATEST PLUMBING TECHNOLOGIES

D E LTA ® FA U CE T

PRESENTED BY

Technology is ever-evolving and helps to make our lives easier and more efficient, but because the changes are so rapid, keeping up-to-date on the latest evolutions in plumbing can be challenging. Delta Faucet has developed several exclusive industry-leading technologies, all of which ensure our products meet the needs of our customers and help you stand out from the competition. Here we break down everything you need to know about the latest technologies in the plumbing industry so you can provide your clients with the information and products to best suit their needs. Touch2O® Technology Spending time in the kitchen has become more efficient with Delta’s Touch2O Technology, which lets you start and stop the flow of water with a tap anywhere on the faucet body. With Touch2O Technology, food preparation has become seamless and clean up is quick and easy. It also helps prevent the spread of bacteria and can save water and energy. A built-in shut off ensures the water flow turns off automatically, making this new technology hassle-free. Touch2O Technology is available on several Delta kitchen and bar faucets, ensuring there is a style and configuration to suit all your customers’ needs. Proximity™ Sensing Technology Proximity is Delta’s unique sensing technology which forms a 4" field around the body of the faucet. Once the user’s hand enters the field, the faucet is turned on. When the user removes their hands from the water stream, the faucet turns off within 2 seconds. Designed to self-calibrate once it has been installed, Proximity saves time by ensuring installation is quick and easy. The surface mount control box makes it easy to access the controls for routine facility maintenance, ensuring you can spend time on more pressing items. H2Optics™ Suitable for commercial and institutional applications, Delta’s H2Optics hands free technology is one of the most advanced sensing technologies in the industry today for electronic faucets and flush valves. With the ability to accurately sense the user’s distance, regardless of external factors such as light reflection, clothing colour and textures or dryness of one’s skin, H2Optics provides consistent, dependable results. Delta now provides both faucets and flush valves with H2Optics technology, so you can have the peace of mind that comes with working with just one supplier. Developed by Delta Faucet, this innovative technology was designed and produced in North America.

trends to watch

A recent National Kitchen & Bath Association (NKBA) survey suggests that there will be some changes in the direction that kitchen styles will take this year across Canada and the U.S. The prevailing trends include: a rise in popularity of the Shaker (plain, simple, utilitarian as seen in many faucet designs) and Cottage (farm house and apron-front sinks are popular, although undercounter trough sinks and freestanding porcelain sinks also work well) styles. Garbage disposals and trash compactors have seen an upswing, which reflects increased attention to trash generated in the kitchen. In terms of finishes, satin nickel kitchen faucets rose from 41 per cent to 63 per cent, while the per cent who specified a brushed nickel faucet fell from 61 per cent to 48 per cent. Bronze and oil-rubbed bronze, polished chrome, polished nickel and stainless steel remain popular. nkba.org

ANNOUNCING THE ARRIVAL OF THE WORLD'S MOST ADVANCED LINE OF FOOD WASTE DISPOSERS The Evolution Series® disposers feature MultiGrind® and SoundSeal® technologies that address the two most common homeowner requests: 1. Grind more food waste without clogging 2. Quiet operation

What is SoundSeal® Technology? A combination of advanced insulation and anti-vibration components. Evolution models with SoundSeal Technology perform 40-60% quieter than standard disposers.* •

40% quieter means you can hold a conversation with elevated voices in the same room.

•

60% quieter means you can hold a conversation with normal voices in the same room

IN S IN K E R ATOR

What is MultiGrind®?

Two-stage technology quickly grinds food waste significantly better than any previous disposer. Three-stage technology allows you to grind almost any food waste. It also includes a Jam-Sensor® circuit that virtually eliminates jams. • celery • potato peels • corncobs • rib bones • other problem foods

Disposers can play an important role in solving the food waste management challenge. Food waste disposers can be an environmentally responsible alternative to transporting food waste to landfills. And, they can help reduce greenhouse gas emissions. At capable wastewater treatment plants, food waste can be recycled to produce methane that can be used as a renewable source of power for the plant. Additionally, certain wastewater treatment plants can process food waste into biosolids to be used as fertilizer. (Check the plant in your area.)

*Results may vary depending on test conditions. Claims are based on average sone values over a sampling period using the Association of Home Appliance Manufacturers (AHAM) test load.

INTRODUCING THE WATCO INNOVATOR® CABLE BATH WASTE SYSTEM: FULLY REPAIRABLE FROM INSIDE THE TUB When you are installing a high end tub, make sure to ask for the new Watco Innovator® Cable System. The Watco Innovator® Cable is fully testable right out of the box so any leaks in the piping don’t get sealed up in the wall. Rarely does a Watco bath waste system need repair. But if it ever should, you’ll never have to cut through thousands of dollars of custom tile or install an unsightly access panel. The Watco Innovator® Cable was created to specifically complement the finest baths. It operates smoothly and reliably. It drains flawlessly in today’s deeper tubs and offers a flow rate that exceeds all other cable drains. It will not self close under the weight of the water when draining. A flexible/pivoting stopper is standard, it prevents damage to both you and the stopper if accidentally stepped on. It is available with flexible tubing (Watco Innovator CableFlex pictured) and standard PVC and ABS full and half kits. And, with Watco QuickTrim®, you can change to one of nine special finishes in minutes without removing the strainer body.

Sump Pump Savvy There are many models of sump pumps on offer and although it may seem to be overkill, it really is not. It takes that many to meet a variety of applications efficiently and cost effectively. By Joe Evans

CLEAR OR Grey WATER PUMPS Often referred to as effluent pumps, clear or grey water sump pumps are designed to pump water that is free of trash, sewage, and other large solids. For most models the solids handling capability ranges from Âź" to Âž". Flow rates range from 10 to 100 GPM and normal pumping heads (vertical pumping height) range from 12' to 30'. Special high head models can produce heads of 70' or more. Most effluent pumps employ oil filled motors. Oil transfers heat from the motor to the pump case and also lubricates the bearings and mechanical seal. Motors are rated for either intermittent or continuous duty. Intermittent duty pumps are the most common and are found in many elevator and rainwater sumps. They are designed for an average duty cycle of 20 min. per hour. Although they can run for longer periods, their life will be shortened. Continuous duty pumps can run 24 hours per day as long as they are located in a sump where incoming water can flow over the motor. These pumps are often found in water features or ponds where 24-hour circulation is required. They are also used for pool draining and other extended dewatering applications. 52

HPAC | MARCH 2011

Special high temperature models are available for laundry and boiler sumps. Water lubricated motors are also available and are often used in water features where aquatic life could be harmed by a leaking oil filled motor.

SOLIDS HANDLING PUMPS The typical small solids handling sump pump is designed to pass a 2" spherical solid. They are used for domestic sewage and other applications where trash and debris might be present in the water. Flow rates range from 40 to 200 GPM and normal pumping heads range from 12' to 35' although special high head models can produce heads of 50' or more. Almost all use oil filled motors and are rated as intermittent or continuous duty. The same duty cycle that applies to effluent pumps also applies to solids pumps. Continuous duty models are often used in water feature applications where relatively large flows are required. The major difference in small solids handling pumps is the impeller design employed. The two types are recessed (vortex) and semi enclosed (two port). Two port impellers allow the solids to pass through the impeller and offer the best efficiency, flow, and head for a given horsepower. Since solids must pass through the impeller, occasional clogging can occur. Recessed impellers use a vortex action to pass solids through the pump without touching the impeller. This reduces clogging; however, performance will be lower than an equivalent two-port impeller pump. <> Joe Evans, Ph.D., who is a trainer with PumpTech, Inc., hosts a popular educational web site pumped101.com. hpacmag.com

Photo Liberty Pumps

ump pumps can be broken down into two major categories -- clear or grey water pumps and solids handling pumps. Within these two broad categories, they are further differentiated by: the type of impeller employed, the design of the motor and the expected duty cycle. We could probably find four or five models that could satisfy 90 per cent of the most common applications, but their cost could be several times the cost of a correctlysized and selected pump.

PRO380-SERIES

LIB E RT Y P UM P S

Short, fat and squatty are a few words that have been used to describe the new Pro380 sewage package from Liberty Pumps. The first “shallow” sewage system to feature QuickTree® technology. While most residential sewage basins are 30" tall, Liberty set-out to design a shallow basin that still offered large holding capacity for longer pump cycles. The longer cycles translate into improved pump and switch life. The result was a 24" deep by 24" wide rotationally moulded polyethylene basin that boasts a whopping 41 gallon total capacity. Although only 24" tall, the increased diameter of the PRO380 provides over 25% more capacity than traditional 18" x 30" basins. Ever dig a hole? Digging wider is usually much easier than digging deeper. That’s the concept behind the PRO380 shallow design. This is especially helpful in difficult soil conditions such as bedrock which is prevalent in some areas of the country. As part of the new PRO-Series, Liberty introduced QuickTree® technology. A mounting system for the floats that allows easy access for servicing. The floats are mounted to a stainless steel tree (or rod) that is located underneath a separate access cover. With the QuickTree® mounting system, float switches can be accessed without removing the pump, main cover and piping. Replacement or cleaning of floats can now be accomplished in minutes outside of the basin by simply removing the access cover and pulling the QuickTree® out of the system. Both pump activation and alarm floats are mounted to the QuickTree®. Other PRO380 features include moulded torque-stops for locating and securing the pump, heavy-duty rubber gaskets moulded to the covers for improved sealing, a clear disposable construction cover to protect the system during rough-in and masonry work; and complete pre-assembly from the factory. The PRO380 series is available in a wide range of horsepower and voltages, both in 2" and 3" discharge; and new “XL” 10' stack test models have been added with UPC approval.

Good IAQ: One Amenity Hotels Can’t Do Without Respiratory illness, allergies and asthma -most hotel operators would consider these ailments to be unwanted guests. But hoteliers who do not pay close attention to their HVAC air filtration system may be placing these disorders on their room service menu. By Lon Edelman

POOR IAQ AND ITS EFFECTS So what is in this “polluted” indoor air? Smoke, fumes, dust, bacteria and other contaminants – many of them a fraction of the size of a grain of sand. And, the average person breathes in about 16,000 quarts of air each day with about 70,000 of these visible and invisible particles entering the respiratory system. It is no wonder that: »» More than three million Canadians have a serious respiratory disease. »» About 2.7 million Canadians have asthma. »» Between 4,000 and 8,000 Canadians can die of influenza and its complications annually. 58

HPAC | MARCH 2011

»» Up to one-quarter of Canadians suffer from “hay fever”type allergies. Poor IAQ is more than bad for one’s health; it is also bad for business. Review the following statistics and consider the potential effects of poor IAQ on hotel employees: »» Roughly 15 per cent of the Canadian population has some form of sensitivity to environmental factors significant enough to affect their lifestyle. »» Asthma sufferers in Canada face 1.1 to 1.8 million restricted activity days every year. »» It is estimated that Canadians spend more than $600 million each year to treat asthma conditions. »» Almost 6.5 per cent of total health care costs in Canada are related to respiratory disease (not including lung cancer). This accounts for nearly $5.7 billion in direct costs and $6.72 billion for indirect expenses. »» Productivity losses due to premature death and disability as a result of bronchitis, emphysema and asthma cost the Canadian economy $2.1 billion a year. »» Employee absenteeism costs Canadian businesses about 2.6 per cent of their total payroll. hpacmag.com

Photo Kimberly-Clark Filtration

t is estimated that indoor air is often two to five times more polluted than outdoor air – a statistic that becomes more shocking when you consider that Canadians spend about 90 per cent of their time indoors. In fact, about one in four Canadians report that they or someone in their household have experienced health problems linked to poor indoor air quality (IAQ). Unfortunately, poor IAQ is prevalent in commercial and institutional buildings, such as hotels. The World Health Organization estimates that onethird of all new and remodeled buildings have unhealthy air and more than 20 per cent of the existing building stock in Europe and North America may be characterized as “sick.”

HOTEL GUESTS SPEAK OUT Just as important as healthy, productive employees are satisfied guests. But some hotel guests find room for improvement at the inn. More than two-thirds of frequent travelers polled in a 2005 U.S. survey said they are concerned about air quality in hotel rooms. They identified odors (68 per cent of respondents) and “stuffiness” (59 per cent of respondents) as being the most frequently encountered IAQ problems. Sixty per cent of the travelers surveyed said they have experienced a range of problems such as poor sleep, runny or stuffy nose, dry nose, sneezing, headache, cough and sore throat as a result of staying in a hotel room with poor IAQ. The issue of bad hotel room IAQ was such a concern that 42 per cent of the survey respondents actually complained to hotel management about air quality conditions inside their hotel rooms.

AIR FILTRATION IS KEY Ideally, airborne contaminants should be eliminated or significantly reduced by a hotel’s HVAC system. While many Canadian jurisdictions do not have specific legislation that deals with indoor air quality issues, there are a number of things hotel operators can do to improve their IAQ – from periodic monitoring of IAQ conditions and checking HVAC systems for mould and other contaminants, to the simple act of upgrading their air filters. In fact, effective air filtration provides the primary defense against indoor particulate pollutants and helps minimize exposure to particles that can be present in bad indoor air. Fortunately, with today’s higher standards in air filtration, it is possible to produce cleaner, purer air and reduce IAQ problems. Contractors with hotel operator customers wishing to improve IAQ have a choice of many new filter designs that provide high particulate filtration efficiency. Upgrading the air filtration system from flat fibreglass to pleated filters with a minimum MERV 8 performance is a good first step in an effort to improve IAQ. Based on ASHRAE Standard 52.2, a MERV (Minimum Efficiency Reporting Value) is assigned to filters depending on the filter’s efficiency in three different particle size ranges. A MERV of 5 is least efficient, while a MERV of 16 is most efficient. hpacmag.com

The ASHRAE 52.2 test provides the efficiency of the filter over three particle size ranges: E1 (very fine particles in the 0.3 to 1.0 micrometer range), E2 (fine particles in the 1.0 to 3.0 micrometer range) and E3 (coarse particles in the 3.0 to 10.0 micrometer range). The E1, E2 and E3 efficiencies represent the true measure of filter performance and give users a more complete picture of what the filter will actually do. When evaluating results of the ASHRAE 52.2 test, HVAC engineers would be wise to review the Fractional Particle Size vs. Particle Diameter Curve that is included with the test report. The curve will provide the efficiency of the filter for the specific particle size of interest. Keep in mind, for example, that lung-damaging dust can be as small as 0.5 micrometers while some bacteria can be as small as 0.3 micrometers. This means that high E1 and E2 efficiencies are critical to providing for good IAQ. Unfortunately, many pleated filters today have very low E1 and E2 efficiencies. Manufacturers of these filters try to divert attention away from poor E1 and E2 performance by instead focusing on MERV and the non-standard “MERV-A” test, which subjects filters in the test to extreme particle loads of very fine particles – many times what the filter would be exposed to over its lifetime. To avoid confusion between the optional MERV A results and the filter’s E1, E2, and E3 Fine Particle Efficiencies, ask to see ASHRAE 52.2 test reports as well as an energy cost analysis of the filters under consideration.

BENEFITS TO HOTEL OPERATORS In addition to improved IAQ, there are other benefits of upgrading a hotel’s HVAC air filtration system including potentially reduced HVAC energy consumption by choosing filters with low resistance to airflow and reduced operating costs, which can be achieved by using longer-life pleated filters. Upgrading filters in the hotel central HVAC system also can help quality for LEED credits and other green building milestones. From an employee health and productivity standpoint, studies have shown that improving the indoor environment can lead to as much as a 20 per cent improvement in worker productivity.

A Balanced Approach The challenge of selecting the right refrigerants to preserve the environment and deliver value to customers. BY Jeff Moe

he HVAC/R industry is facing a major challenge in addressing the phase-out of nearly all current commercially-viable refrigerants over the next few decades. The need to transition is acknowledged and supported by the equipment industry, but the transition must address both environmental stewardship and customer value. Developing a refrigerant solution is a complex problem that must consider ozone depletion potential (ODP), global warming potential (GWP), energy efficiency, safety, system cost and application fit. THE SEARCH FOR A BETTER REFRIGERANT

One of the constant themes throughout the history of the HVAC/R industry is the search for a better refrigerant. In the early years the primary focus was simply on finding a refrigerant that would provide effective cooling. Many of the early refrigerants such as sulfur dioxide, methyl chloride and ammonia are toxic or flammable. Chlorofluorocarbon (CFC) refrigerants were introduced in the 1930s as safe alternatives to the dangers of the chemicals used before them.

Figure 1 Timeline of refrigerant usage

CFCs came to dominate first refrigeration and later HVACR because of their safety and efficiency. Hydrochlorofluorocarbons (HCFCs) were added later as additional application refinement was added to the overall portfolio of solutions. Then in the 1970s scientists discovered that CFCs, and to a lesser extent HCFCs, were contributing to the depletion of the ozone layer. In 1987, the Montreal Protocol went into effect and started with a 50 per cent phase out of CFCs, and then later moved to a 100 per cent phase out of CFCs. In addition, HCFCs were added to the list of chemicals controlled under the Montreal Protocol and phase-out dates were established. Because of their low ODP, the phase-out dates for HCFCs were set at 30 or more years into the future. The HVACR industry replaced CFCs with hydrochlorofluorocarbons (HCFCs), which have a much lower impact on the ozone layer than CFCs and also with hydrofluorocarbons (HFCs) which have zero ODP. However, later concerns arose that many of the chemicals that were being phased in because of their favorable ODP contributed to global warming. The Kyoto Protocol, created in 1997, addressed the issue of global climate change. Kyoto set reduction targets for greenhouse gases, including HFCs, in developed countries. As a result, HFCs are now under pressure for a phase down consideration.

Figure 1 provides a summary of the major legislative actions involving refrigerants in the developed and developing countries, including both the Montreal and Kyoto protocols. The dates on the chart are for the United States and Canada while dates in other countries vary. Even though the CFCs and HCFCs are global warming gases, they are not covered under the Kyoto Protocol due to their separate coverage under the Montreal Protocol. Likewise HFCs that continued on page 66

from HVAC equipment is now 20 to 600 times lower compared with the older CFC chiller designs. These reduced leaks rates now bring the direct percentage of global warming impact to under five per cent of the total global warming impact for the application. The other 95 per cent (or more) of the environmental impact comes from the generation of power used by the HVAC system. Today, 70 per cent1 of this power is being generated by the burning of fossil fuels that are also producing greenhouse gases. When you consider both the direct and indirect impact of refrigerants on the environment, then fluorocarbons, because of their high energy efficiency, can be the most environmentally-responsible refrigerant available today for many applications.

Fortunately, the Montreal and Kyoto protocols have set out dates to ensure long-term availability. Even when production of a refrigerant stops, recycled, recovered and stockpiled supplies can continue to be used without restriction. For example, production of CFCs ended in 1996 but stocks of these refrigerants are still readily available. The price of R-12 rose considerably after new production was banned in 1996 because of taxation and heavy automotive use but the price has dropped more recently as automotive segment demand has declined.

EVALUATING NATURAL REFRIGERANTS

The importance of considering the indirect environmental impact extends to evaluating natural refrigerants. For example, refrigerants such as CO2, hydrocarbons and ammonia have zero ODP and a very low GWP but they present other concerns. CO2 has potential as a low temperature refrigerant in refrigeration applications but it has a very low efficiency in HVAC applications â&#x20AC;&#x201C; more than 20 per cent below the efficiency of R-22 and R410A, due to operation above the critical point of CO2 in these applications. continued on page 68 hpacmag.com

To get the same cooling tonnage today's equipment would therefore consume more than 20 per cent additional energy with carbon dioxide as it would with fluorocarbons. It is clear that switching from fluorocarbons to CO2 to reduce the direct environmental impact, which constitutes less than five per cent of the total, while significantly increasing the indirect impact, which makes up 95 per cent of the total, would not be a good tradeoff. Hydrocarbons can be used in stationary air conditioning applications but they present safety issues in application, service and recovery since they are highly flammable. Ammonia has potential for low temperature and process chiller applications but its flammability and high toxicity limit its use. REFRIGERANT SELECTION

The public and policymakers should consider all aspects of the environmental impact of refrigerant alternatives for the future including ODP, GWP, energy efficiency and atmo-

spheric life. There is no perfect refrigerant and, barring breakthroughs, one will not be available for the foreseeable future so every refrigerant choice is an effort in compromise. We need to utilize a balanced approach in selecting refrigerants and not focus on one or two factors to the exclusion of others. A more thorough review of the available chemicals will help to understand the impacts of these compromises. Figure 2 above compares the ODP, GWP and energy efficiency of today's commercial refrigerants and potential future refrigerants. While there are no perfect refrigerants, the chart shows that of the refrigerants available today, R123 strikes a good balance between ODP and GWP. The use of one other fluorocarbon on this chart that also combines good ODP and GWP, R-32, is limited because of its flammability. The equipment industry is under tremendous pressure to move to a new generation of refrigerants with low ODP and low GWP. Refrigerant producers are working on developing new refrigerants with negligible ODP, very low GWP, high energy efficiency and high levels of safety. Equipment manufacturers are analyzing new refrigerants based on their energy efficiency, safety and emissions. Everyone would like to use a refrigerant that will be available forever and never phased out but there are no commercially viable refrigerants like that today. Focusing on maintaining a balance between achieving the lowest possible refrigerant emissions, along with the best possible energy efficiency, is the key to being both environmentally and economically responsible. Lastly, achieving this balance in a cost effective manner is critical in order to make these new designs affordable for the end user. <> Jeff Moe is director, global policy and advocacy for the Center for Energy Efficiency and Sustainability at Ingersoll Rand. 1 U.S. Energy Information Administration

he vast majority of contemporary solar thermal systems fit into the broader category of hydronic systems. They just happen to use solar collectors rather than a boiler as their heat source. As such, the same physics that govern air collection and removal in conventional hydronic systems remain in effect in solar thermal systems. Much of the hardware used for these purposes is also very similar. Figure 1 shows a typical closed-loop solar thermal system of domestic water heating. An antifreeze solution circulates between the collector array and the heat exchanger within the storage tank. All closed loop solar subsystems require a “purging group” consisting of a fluid inlet valve, a fluid outlet valve and a third valve in between. The third valve can be either a ball valve or a check valve. Figure 2 shows a closeup of both options. In some systems, the three valves that make up the purging group are installed as individual components. In others, these valves are part of a preassembled solar circulation station. Of the two options shown in Figure 2, the one using the check valve provides for both purging and prevention of reverse thermosyphon flow when the storage tank is warmer than the collectors. If a ball valve is used in this position, a separate check valve must be provided elsewhere in the

should remain open for several days during which the system is operating and air bubbles are likely being formed within the collectors. After this time, the ball valve should be closed to protect the vent from potentially high stagnation temperatures. The ball valve should be specifically rated for solar applications, or otherwise rated to withstand service temperatures of at least 350F. Many solar subsystem circuits also contain an air separating device, either as a separate component, or built into the solar circulation station. This device works to continually collect and purge any remaining air. It is normal to see a slight drop in pressure when the system is deareating itself within the first few days of operation. Annual service checks on the system should include verification of system pressure. When necessary, system pressure can be boosted using a hand pump and a short length of hose. Loosely connect the free end of the hose to the fluid inlet valve. Pump some fluid through the hose and let it leak out of the loose connection. This helps to dis-

place air in the hose and hose connection. Tighten the connection, open the fluid inlet valve, and pump in fluid while watching the pressure gauge. When the desired pressure is reached, close the fluid inlet valve and disconnect the hose. Put a written tag on the fluid inlet valve indicating the date at which fluid was added, the type of fluid added and the final pressure gauge reading. There you have it: Simple and effective ways to get fluid into and air out of a solar collector circuit. A properly deareated collector circuit will operate with very little detectable noise and provide good heat transfer for many years. <> John Siegenthaler, P.E. is the author of Modern Hydronic Heating.

WATTS WATER TECHNOLOGIES

PRESENTED BY

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

Keep your business and yourself in the clear on expense issues.

BY HANK BULMASH

here are typically two ways that companies and their shareholders get into trouble with Canada Revenue Agency (CRA) over expense issues. The first results from expenses that are not fully documented. The second results from expenditures that can be categorized as benefiting employees, shareholders or their relatives. Undocumented expenses often arise when casual labour is used. This is a problem for restaurants, contractors or any business where casual help is paid from general funds and names, social insurance numbers and addresses are not obtained and tax remittances are not made. Similar problems can also arise when payments are made to offshore individuals or entities and proper documentation is not collected. It is bad enough that a business can be denied a deduction due to improper record keeping, but there are much worse outcomes that shareholders might be subject to. Imagine this scenario. You need an improved work-in-process and billing system. You find a company that will design the program for you for much less than you expected to pay. You learn that a programmer in Ukraine will do the work and he will only accept payment in cash in Canadian dollars (banking is very primitive in Ukraine and this is not an unusual provision there). To protect yourself, you negotiate a deal that allows you to make payment when the program is installed and working to your satisfaction. Finally everything works, the programmer demands payment in cash and you pay him $30,000, as agreed by contract. Two years later, CRA reviews your books and denies the deduction for $30,000. CRA claims you have no proof that 76

the amount the company paid actually went towards buying the software. You have a contract and a receipt, but CRA says that is not enough. They want the programmer's photo ID and his social insurance number in Ukraine. They want to notify the Ukrainian government that this fellow earned $30,000 in Canada. You now have no way of obtaining the information and your accountant tells you to accept the reassessment. It is not worth fighting. That increases your company taxes by about $5,000. Not good. But CRA is not finished. They claim that you appropriated the company funds yourself and charge you tax on the $30,000. Prospective bill: $14,000. They suggest they may impose penalties and interest that will add about $8,000 to those charges – now you are up to $22,000 personally and $5,000 in the corporation. The tax on the $30,000 you spent legitimately is now nearly equal to the cost of the software you bought. Ouch! This is not a fantasy. As outsourcing to offshore suppliers has grown, CRA’s position on offshore payments has hardened. Its fear is that domestic companies will have the opportunity to shift significant funds outside the Canadian tax zone if it does not insist in a very high level of documentation – higher than that required of a Canadian supplier. This can be a major source of trouble, but it is not the only one. The more common issue is expenditures that CRA feels result in taxable benefits to employees, shareholders or their relatives. This can lead to denied deductions to the company and a taxable benefit inclusion to an individual. Basically, an expenditure is deductible as long as it is a reasonable amount and is laid out to earn income. For the most part that is not a problem as long as payments are made to arms length suppliers for things that do not benefit employees and shareholders. But what happens when people associated with your firm can get personal benefits? And what does CRA mean by personal benefits? Basically CRA defines personal benefits as anything that enriches employees, shareholders, or their relatives. Typical benefits are: cash and loans, cars and free parking, club memberships, gifts, entertainment and meals, travel, counseling, insurance and education. hpacmag.com

The Taxman Cometh

Tax rules relating to cars are well known and they provide an excellent insight into tax issues related to benefits. If a company makes a car available to an employee, the employee will have to pay tax on the value of the benefit, which is computed by formula. The word “available” is important here. It means that if the employee has access to a vehicle, he is treated as though he received a benefit whether or not he actually used the car for personal use. This sounds unfair and, in certain instances, it is. CRA’s position is nonetheless understandable. The rule evolved to avoid a “he said, she said” scenario where CRA wanted to tax the auto benefit and the employee insisted the car was not actually used personally. Similar availabil-

eight weeks, about two months operating expenses will be denied to the corporation. Then, CRA will compute the benefit conferred on the family for the property use. So, doing nothing does not work. What should you do? The best course of action is for the corporation to determine what period it can deduct expenses for (based on whether or not shareholders have used the property and whether or not they paid fair rent). Then determine the amount of the taxable benefit (again based on usage and whether or not rent was paid). Do not ask CRA what amount the benefit is. There are several ways to determine the amount of the benefit. By doing it yourself, you can avoid the onerous con-

“If there are no additional costs, why should there be a benefit? This is the “no harm, no foul” theory of income tax, which does not apply in Canada.” ity rules cover other benefits as well, such as club memberships and parking spaces. The biggest risk to a company and its shareholders is to have expenses denied to the company and the value added to the shareholder’s income. If you take money from your company and you pay tax on it, the value can be charged to the company as a remuneration expense. You will pay tax on the receipt but since the company receives a deduction, there is no double taxation and no penalty. A much worse situation can occur where a shareholder receives what is a benefit in CRA’s eyes, but the corporation has treated the expenditure as a normal expense and not a benefit to the shareholder. For example, let’s say your company does business in Vancouver. Hotels are expensive there and prices are increasing, so your company buys a condo for business use. The cost of owning the condo is not much more than the hotel bills your company used to pay. When the condo is vacant, you and your family use it occasionally when vacationing in BC. When this occurs many taxpayers do not reflect the condo use as a taxable benefit. Their argument: it costs the corporation nothing for the shareholders to use an otherwise vacant property. If there are no additional costs, why should there be a benefit? This is the “no harm, no foul” theory of income tax, which does not apply in Canada. The personal use of a corporation's assets by a shareholder will result in a taxable benefit whether or not it costs the corporation anything to provide the benefit. In this situation, CRA’s will first deny the company a prorata share of expenses. If the family used the condo for hpacmag.com

sequences of having CRA base its benefit value on “availability” and expected return on investment rather than market rental rates, which are often lower. CRA can base its determination on a number of alternatives since the courts have been split as to: whether the benefit should reflect the cost of the asset or its fair market value; on market rents or return on investment; and on whether the benefit should be based on actual usage or “availability.” Given a chance, CRA is likely to pick the most expensive choice. In general, the best scenario is to pay the corporation the market value rent for the time you use the property and allow other employees or the public to use the property at the same rate. That lets the corporation deduct 100 per cent of its operating expenses. It also provides a strong, defensible market value position and avoids tax charges for availability. The key to avoiding problems with expense deductions is clarity. Obtain full documentation for all service providers, particularly those located offshore. Work hard to compute reasonable values for benefit determinations when benefits are conferred on shareholders, employees and their relatives. Be aware of changes in the law -- review the CRA publication dealing with benefits annually. This is an area where things do change and you should stay current in order to protect yourself. The downside is very expensive. <> Hank Bulmash, CA, MBA, is senior partner with Bulmash Cullemore Chartered Accountants and is president of its consultant subsidiary BusinessLab Inc.
