VerEco Homes’ interactive exhibit demonstrates the future of green home design, and the ecological and economic benefits of building and living smart. Presented by SaskPower eneraction, the VerEco Home will be open for public tours, four times a day, for one year. Students from across the province will also be touring the Net Zero Home exhibit during special class tours. A first for Canada, the Net Zero Home exhibit will also be of interest to design and construction professionals, including architects, builders, contractors, designers and tradespeople. Education seminars on green building technologies for members of the construction industry will be offered throughout the year. WHAT IS A NET ZERO HOME? Considered by many to be the future of residential construction in Canada, a Net Zero home produces as much energy as it consumes annually. Three strategies are employed in achieving Net Zero: 1. REduce total energy consumption 2. REuse as much energy as possible 3. REplace remaining energy requirements with sustainable energy including photovoltaic systems (solar energy). page 6 The driving force behind the opening of the unique demonstration home is Ronn Lepage, president of VerEco Homes, a new Saskatoon company focused on helping builders and owners to design, construct and maintain ultra-low energy homes. In designing the 1,220 square foot VerEco Home, Lepage worked in tandem with world-renowned building scientist Dr. Rob Dumont. Considered by many to be one of the founders of the green building movement in Canada, Dumont retired from the Saskatchewan Research Council in 2008. He is now a busy consultant on low energy building technologies. “Dr. Dumont led the design team. Because of his vast knowledge and experience, he has the ability to take an energy-saving technology and implement it in a very cost effective way,” says Lepage. The architectural firm of BlueSpot Consulting in Toronto took Lepage’s vision and Dumont’s technological savvy and created a visually attractive and functional blueprint for smart living. “We wanted the VerEco home to look unique, and it does,” says Lepage. The VerEco Net Zero Home employs REducing technologies, including a compact design, a super-insulated and sealed building envelope including R100 attic insulation and 16 inch-thick R60 walls, triple glazed energy efficient windows and passive solar design. Energy consumption in lighting and applicances is REduced through the use of ENERGY STAR® appliances, low-flow water fixtures, and LED lighting. presented by: To REuse heat energy in waste air and water, the home uses heat recovery ventilation (HRV) and drain water heat recapture (DWHR) technologies. Solar thermal panels on the southfacing exterior of the home produce the energy to heat water for the home. Electricity is generated using a state-of-the-art photovoltaic system, to REplace remaining energy requirements. Lepage’s goal is for the VerEco Home to achieve LEED Platinum certification. LEED Canada for Homes, launched in March 2009, certifies green homes using criteria in eight different categories: site selection, water efficiency, materials & resources, energy & atmosphere, indoor environmental quality, location & linkages, awareness & education, and innovation. The green measures are verified on-site by a third-party verification team. Platinum is the highest level of achievement in the LEED third party certification program. “What’s unique about the VerEco Net Zero Home is that its systems are all integrated and very cost efficient. Green construction has been viewed in the past as very expensive, but we set out to prove that it is cost effective,” says Lepage. “The exhibit demonstrates not only environmental and energysaving features, but also the affordability of green building.” The savings will continue after homeowners occupy the VerEco Home, adds Lepage. “The homeowner will save about $4,000 a year in electricity costs. If you multiply that by the 50 yearlifespan of the home, at today’s electricity costs, that’s a total saving of $200,000.” The Net Zero home also reduces water consumption by about twothirds. “In Saskatoon, a typical family of four uses about 300 gallons of water per day. Our target is to reduce that consumption to about 100 gallons of water per day,” says Lepage. The home’s environmental imprint was also reduced by sourcing as many local products as possible. “We chose low or noVOC building materials wherever possible, from paint to flooring. Recyclable materials were also important,” says Lepage. The ready-to-move (RTM) home was constructed to VerEco Homes’ specifications by Nu-Fab Building Products. “It was important to me to find a locally owned and operated builder who had the capacity to grow with us and embrace these new technologies,” says Lepage. page presented by: 7 Z1620050.g27 Pony Tab/Terry/Blue PDF Canada Mortgage and Housing Corporation Congratulations to the VerEco Home on your commitment to Sustainable Housing.

Designed and built by Saskatchewan professionals for Saskatchewan’s climate, the home showcases smart, green building. It will: • Provide efficient use of potable water, • Provide efficient use of energy, • Be built using environmentally preferable products, and • Have high indoor environmental and air quality. The home will also be built, operated, and maintained in an affordable manner. Net zero means that a home has an annual net energy consumption of zero; it uses the same amount of energy as it generates. Energy consumption is based on heating and cooling a home, heating water, and operating the home’s lights, appliances, and miscellaneous devices. The VerEco Home saves energy by reducing the amount of energy the home requires, reusing waste and excess energy, and replacing conventional energy sources with alternatives. The VerEco Home is also intended to reduce construction waste by approximately 75%, reduce water consumption by over 66%, and improve indoor air quality. As well, its compact design helps reduce construction costs, making the home more affordable. The home’s purpose is to reduce environmental impacts while providing a high standard of living for its inhabitants. INNOVATIVE Design DESIGN BASICS The VerEco Home was designed over a 9-month period with input from many different consultants. This integrated design team included architects, scientists, homebuilders, and engineers. Frequent team meetings were held, and the design was completed in May 2010. Integrated Design Team: VerEco Homes Inc. Dumont and Associates Saskatchewan Research Council WSE Technologies Rock Paper Sun Interlink Research Inc. Sun Ridge Group NuFab Building Products MidCon Engineering Ltd. BlueSpot Consulting Pinter and Associates page presented by: 9 INNOVATIVE DESIGN PASSIVE SOLAR Part of the design process included selecting a proper orientation for the house to allow for passive solar heating and cooling. The home’s orientation ensures that it receives enough sunlight on its South side for the passive solar design to work. As well, special concrete floor tiles weighing 18 pounds per square foot were designed to provide nearly 10,000 pounds of thermal mass for passive heating and cooling. These tiles also significantly increase the durability of the flooring, and are recyclable. For more information about passive solar design, go to page 20. INNOVATION Several innovative elements were a part of the VerEco Home design. The roof design is especially sophisticated, since it combines an appealing look with technical elements. A roof slant of 62 degrees on the south side was Passive solar heating and cooling uses energy from the sun to help maintain a comfortable temperature within a structure. Window size and placement, building orientation, and thermal mass are a number of elements used by passive solar technology. page 10 (Continued) chosen because it optimizes the sunlight angle for the photovoltaic panels while ensuring that snow buildup is minimized. As well, the roof overhang acts as an awning to provide shade in summer and let the sun in during winter heating months as part of the passive solar design. COMPACT DESIGN A major goal of the design team was to achieve a compact and efficient floor plan. Less space means less required energy. The first VerEco Home design was 1600 square feet, but the current design is less than 1300 square feet. This reduction was designed to keep roughly the same amount of living space, for example, by eliminating hallways. A compact design also allows for savings in construction costs. At a total construction cost of $200/square foot, reducing the square footage saved $60,000. Thermal mass relates to a material’s ability to store heat and dampen temperature changes. A large amount of thermal mass, for example, concrete, will absorb heat when its surroundings are warm, and release heat when its surroundings are cool. presented by: SITE SUSTAINABILITY An important part of the home’s impact on the environment is the sustainability of its final resting place. The site should maintain as much permeability as possible, keeping runoff to a minimum. Landscaping should also help manage the home’s water demand, which can be done through xeriscaping. Finally, the roof design allows for significant rainwater capture. One inch of rain will result in over 3000 litres of water captured. This helps reduce the site’s water demand as well. LOCATION AND COMMUNITY Although the VerEco Home will spend the year at the Western Development Museum site, it will eventually be moved and used as a residential home. When it is moved to its final resting place, it will be at Sarilia Country Estates, located along the North Saskatchewan River 25 minutes away from Saskatoon. Less than 50% of the site will be disturbed at Sarilia Country Estates. That is, less than 50% of the lot area will be used for the house, its deck, and driveway. As well, the entire lot surface will be permeable, including the driveway. Sarilia Country Estates was chosen as a location for a number of reasons. The first is that Sarilia adheres to green design principles, such as attempting to preserve natural drainage patterns, and requiring dark sky compliant outdoor lighting. Passive solar design is also encouraged. As well, Sarilia provides access to open space, and requires xeriscaping to reduce water consumption. Finally, Sarilia Country Estates provides a $9,000 BuildGreen rebate that reduces the cost of the home. What does dark sky compliant mean? What is xeriscaping? Dark sky compliance means that lighting does not contribute to light pollution. This is usually accomplished by ensuring that lights face downwards and are properly covered. Xeriscaping, which means “dry landscaping”, is a way of landscaping or gardening that reduces water consumption. Drought-tolerant plants are used and run-off is minimized. page presented by: 11 50 Reasons to visit General Compact Design Passive Solar Design Roof Design (slope and awning) Water resistant flooring Rainwater capture system Minimum envelope leakage Sealed ventilation ducts Insulated hot water distribution system No air conditioning The Energy Detective (TED) Energy Monitoring System Windows Doors Cellulose Insulation Forest Stewardship Council (FSC) Lumber Solar thermal system Greywater recycling EnergyStar hot water heater Phantom energy circuit Photovoltaic (PV) Hardie Board Exterior Cladding Metal Roofing Dark sky compliant lighting Concrete floor tiles Light Emitting Diode (LED) Lighting Artwork from recycled material Slant fin radiator Localized thermostats EnergyStar Fridge EnergyStar Dishwasher Walk-up pantry Concrete counter top Composting catcher Recycling center Bamboo flooring Low flow faucets Low flow showerhead Low flow toilet Drain water heat recovery Linoleum flooring EnergyStar clothes washer Clothes line Prefab concrete walls Spray-in insulation in headers Passive Radon ventilation Access to open space Erosion controls during construction Over 50% of lot undisturbed 100% xeriscaped 100% permeable lot No irrigation Great Room Bedrooms Bathrooms Laundry Foundation Future Location (Sarilia) LEGEND = Smart Economics = Site Sustainability = Innovative Design page 12 Kitchen = = = = Energy Efficiency Water Efficiency Materials and Recycling Indoor Air Quality presented by: Expert Series The Expert Series is a series of lectures by specialists in the community about various green building topics.

Treating water to a potable level requires chemical and energy inputs. Whenever water can be conserved, it reduces the amount of energy and chemicals used in treatment, and helps preserve water resources. Hot water also requires energy to heat it. It’s especially important to recognize that many uses of water do not require it to be potable. For instance, it’s not necessary to flush a toilet with water that is safe for drinking. Conserving water also helps reduce the amount of wastewater generated by a home, which can be costly and energy-intensive to treat. (Source: Water.org) A typical Saskatoon home uses 300 liters of potable water per person per day. This means that a typical family of four would be using 1200 liters of drinkable water per day. With the VerEco Home’s water efficiency and conservation features, though, the home’s water use will be reduced over 66% to less than 100 liters per person per day. The VerEco Home will conserve water using several methods. First, all of the home’s water fixtures are very high efficiency. This includes taps, toilets, showerheads, and more. Additionally, the VerEco Home will capture and re-use greywater from the bathtubs, bathroom sinks, and clothes washer. Greywater is a type of wastewater. Household wastewater can be grouped into two categories: greywater and blackwater. Blackwater, or sewage, is water that has been used to flush the toilets, while greywater has been used elsewhere in the home. Greywater comes from sinks, the dishwasher, baths or showers, and the kitchen, among other places. Water efficiency and conservation are huge factors in green design and sustainable living. Fresh water is one of the Earth’s most scarce resources. page 16 Only 1% of the Earth’s water is available for drinking water (Source: City of Saskatoon) presented by: In the VerEco Home, greywater will be collected from its cleanest sources. The kitchen sink and dishwasher will not provide greywater for reuse because of the high level of food particles and other contaminants in the water. Once the greywater has been collected, it will be filtered, chlorinated, and then used to flush the home’s toilets. Recycling this water will help to reduce the home’s use of potable water. Finally, the VerEco Home’s roof has been designed for easy rainwater capture. 90% of the roof surface is dedicated to rainwater harvest. Once captured, cisterns will be used to store the rainwater. Every drop counts! Leaking taps and plumbing fixtures are pouring money down the drain! A dripping tap can waste up to 3,400 litres per month, and a leaking toilet can waste up to 7,800 litres per month for a total dollar value of $16/month or $192/ year.

How does the home achieve this? First, it’s important to understand how a typical home functions. CONVENTIONAL HOMES A home consumes energy in three areas: -Space Heating, -Domestic Hot Water, and -Lights, Appliances, and Miscellaneous. The average Saskatchewan home draws energy from SaskPower, which is generated by: -Coal (48%), -Hydro (25%), -Natural Gas (22%), and -Wind (5%). Energy is usually lost or wasted through: -Poor insulation (walls, ceiling, windows), -A leaky building envelope, and -Low efficiency appliances and mechanical. If the VerEco Home were built to minimum construction standards, it would require over 40,000 kWh of energy per year. This includes over 22,000 kWh for space heating, over 8,000 kWh for domestic hot water, and over 8,500 kWh for lights, appliances, and mechanical. If all of the 40,000 kWh of energy were supplied by conventional offsite electricity, the VerEco Home The design team used Natural Resources Canada Hot2000 software to model homes and estimate their energy requirements. would have annual energy costs of about $4,000. This is because, in Saskatchewan, each kWh of electricity costs 10.86 cents. As well, each kWh generates 0.832 kg of greenhouse gas emissions. If the home’s electricity were supplied conventionally, it would generate around 33 tonnes of greenhouse gas per year. VERECO HOME To achieve net zero, the VerEco Home design team made a plan to: REduce the amount of energy required, REuse waste or excess energy, REplace conventional nonrenewable off-site energy sources with sustainable on-site ones. Reducing the amount of energy required can be through improved building design, reduced hot water consumption, and efficient appliances. Reusing waste energy can be done with technologies like heat recovery ventilation and drain water heat recovery. Conventional energy can be replaced with alternative energy, such as passive solar, solar hot water, wind, geothermal, and photovoltaic. What is a kWh? A kilowatt-hour (kWh) is a way of measuring energy use. It means 1000 Watt-hours (Wh), where Watts measure power, and hours measure time. For example, if a 100-Watt light bulb were used for one hour, that would equal 100 Wh, or 0.1 kWh. page 19 potential energy efficiency strategies Space Heating/ Cooling Domestic Hot Water Lights, Appliances, Mechanical Reduce Compact design Massing and alignment Passive Solar Super insulated envelope Air barrier Low flow shower and taps EnergyStar hot water heater, dish washer and clothes washer CFL or LED lighting EnergyStar appliances Phantom energy Reuse Heat Recovery Ventilation Drain Water Heat Recapture Heat from electrical appliances Replace Solar hot water Geothermal Wood stove Solar hot water Geothermal Wood stove Photovoltaic Wind Micro Hydro PASSIVE SOLAR The home’s passive solar design captures the sun’s energy by using a ratio of south window area to floor area of 6%. This means that the area of window is 6% of the area of heated floor area, which is the optimum balance between capturing heat and reducing costs for this particular home. The home’s south-facing windows are the optimum size and orientation to allow the sun’s energy into the living space. Once the sunlight is in the building, slate-coloured concrete tiles store the energy. June 21 12 noon December 21 12 noon The roof overhangs help to regulate how much sun comes into the building by blocking the sun in summer, and allowing sunlight in during the winter. When the concrete tiles absorb heat, they slowly release it throughout the day, warming the house. As well, to maximize sunlight What’s and improve insulation, the home’s windows are triple-glazed and an R-value? rated with an approximate R-value of 6. An R-value measures how well something insulates against heat loss. Higher R-values show that the material is a better insulator, while lower values mean that it’s less effective. Typical new homes would have about R-20 walls and R-40 ceilings. page 20 presented by: Insulation, Air Barriers, and Windows The VerEco Home’s building envelope has been super-insulated to ensure optimal indoor environmental conditions throughout the year and to drastically reduce the amount of energy required for heating and cooling. The home’s walls are constructed to provide R-60 level insulation. They are 16 inches thick, and are filled with cellulose fiber insulation. Cellulose fiber insulation is made out of recycled newsprint that has been treated for fireproofing. Not only does this insulation help recycle old newspapers, but it also stores carbon that would otherwise be released into the atmosphere as greenhouse gases. Double Wall Construction There is a polyethylene air barrier on the inside of the wall. Approximately one third (1/3) of the energy required to heat and cool a typical home is used to counteract air infiltration and escape. The home’s air barrier significantly reduces the number of unwanted interior-exterior air exchanges. It allows for 1 air change per hour. The insulation in the VerEco Home ceiling provides an R-value of 100. It’s important to have a higher level of insulation in the ceiling because less expensive insulation can be used. A well-insulated ceiling allows the home to be much more energy efficient. In the average home, windows account for up to 25% of the total heat energy loss. The windows Low of the VerEco Home, as emissivity explained in the Passive Solar section, are all means that a material does triple-glazed. With an not emit energy by radiation approximate R-value very easily. Low emissivity (low-e) of 6, the windows are windows help keep heat from entering very high quality. They the home from the outside during are also equipped summer, and they also keep heat that with low emissivity has been absorbed into the home’s coatings and have thermal mass and radiated into argon gas between the the air inside the house glazings. during winter. page presented by: 21 SPACE HEATING AND COOLING Although seemingly contrary to the home’s green design strategy, electric heat was selected for the VerEco Home. This was done for several reasons: - The heating energy requirements for the home are very low, - Electric auxilary heat has a low capital cost, - Electric provides a very efficient source of heat energy, and - Each room is a separate zone for maximum control and minimum usage. Excess capacity from the home’s solar hot water panels will be used for space heating, which will be done using baseboard convection heaters, since the home has no furnace. As well, a super-insulated building envelope combined with high thermal mass, along with external shading for the south windows helps to maintain comfortable indoor temperatures during the hot summer months. Since this eliminates the need for space cooling systems, there is no air conditioner in the VerEco Home. The VerEco Home will also use a heat recovery ventilation (HRV) system to recapture heat energy from exhaust air. In a home as well insulated and airtight as the VerEco Home, adequate ventilation is very important for fresh air and moisture control. Without proper ventilation, air quality becomes an issue and moisture can damage the home. HRV systems allow warm, stale air from inside the house to heat incoming fresh air from the outside. This heat exchange is done without the two streams of air mixing by using a special exchanger. This offers improved climate control for the home, as well as the ability to capture and reuse waste or excess heat. DOMESTIC HOT WATER Personal hot water use in the home is significantly reduced through the use of restricted flow showerheads. EnergyStar appliances, such as the dishwasher and clothes washer, reduce hot water consumption as well. An extremely efficient EnergyStar hot water heater helps reduce wasted energy, as does the compact design of the home’s hot water distribution system. Heat Recovery Ventilator Stale air from inside Pre-heated fresh air to inside page 22 Fresh air from outside Stale air to outside presented by: Your water heater is one of the biggest energy users in your home, second only to the furnace. The home’s solar hot water panels generate a significant amount of the total energy required to (Source: City of heat the home’s water. Saskatoon) As well, drain water heat recovery systems in both bathrooms recapture heat from waste hot water. Drain Water Heat Recovery System Alternative Energy The VerEco Home includes solar thermal systems to provide hot water for domestic hot water and space heating. Solar photovoltaic panels will generate electricity for lights, appliances, and mechanical. Solar Photovoltaic Panels The difference between the two is that a solar thermal system uses solar energy to heat water, while photovoltaic panels convert the same energy into electricity. page presented by: 23 Z1620060.J27 SP/Terry/Blue page 24 PDF presented by: Lights, Appliances, and Miscellaneous The home uses highly efficient compact fluorescent light (CFL) and light emitting diode (LED) bulbs. Energy requirements are also significantly reduced with EnergyStar appliances throughout the home. Some of these appliances include the refrigerator, freezer, and dishwasher. Using these appliances can reduce the energy used by up to 70%. The VerEco Home will also include phantom energy circuits. These circuits are connected to a switch that can cut off energy flow to idle electric appliances and devices. Phantom energy is the term used to describe energy consumed by electric appliances and devices while switched off or in standby mode. Phantom energy load accounts for about 5% of an average home’s energy consumption. With all of the above reductions in demand and reuse of waste and excess energy, the home’s energy requirements were reduced from 40,000 kWh to 9,500 kWh. This lower demand will then be supplied using alternative energy. Compact Fluorescent Light (CFL) bulbs use at least 66 per cent less electricity than incandescent light bulbs and last 8 times longer. Seasonal LED light strings use at least 90 per cent less electricity than incandescent light strings. In fact, it takes as much electricity to power one small incandescent light bulb as it does to power 140 LEDs. (Source: SaskPower) According to SaskPower, almost half (46%) of the electrical energy used in the average Saskatchewan home is to power large and small appliances. About 21% of energy use is for lighting. page presented by: 25 MATERIALS & RESOURCES The VerEco Home’s design team set 5 resource and material conservation goals to reduce environmental disturbance. The goals: 1. The home was to be constructed from locally produced, environmentally preferable products and materials 2. Products and materials were to be durable and sourced from renewable or recyclable resources 3. Only low emission ecofriendly paints, sealants, and insulation were to be used 4. No environmental contamination or degradation from the construction process was to be tolerated 5. The construction process needed to be both efficient and low waste. One way construction waste was minimized was through the design of a 48’ by 32’ floor, which uses standard material sizes. Prefabricated (prefab) construction methods were chosen for the VerEco Home because they met the team’s material and resource requirements. Prefab achieves between 50% and 75% less waste than traditional on-site construction and takes less time. Floor System Waste page 26 presented by: Z1620100.j27 Pony Tab/Terry/Blue PDF Z1620120.j27 Pony Tab/Terry/Blue PDF page presented by: 27 INDOOR AIR QUALITY The quality of a home’s interior environment is just as important as the relationship between the home and the exterior environment. To that end: • Having no combustion gas appliances reduces inhabitant exposure to toxins. • Continuous outdoor venting through the heat recovery ventilation system (HRV) maintains high indoor air quality. • The HRV system removes excess airborne moisture from bathrooms and kitchens. • During construction, continual contamination control and a preoccupancy flush were performed to eliminate any volatile organic compounds. • A passive ventilation system eliminates inhabitant exposure to gases such as Radon. • No attached garage helps reduce the risk of contamination from automotive pollutants. • MERV 13 air filters work with the home’s HRV system to remove breathable-sized particles like bacteria and mold spores.
