An initiative to demonstrate sustainable housing at the national scale, initiates by the CMHC . The creation of communities based on the health and comfort of occupants, on energy efficiency, on renewable energy production, on resource conservation, on reducing environmental impacts and on affordability. Construction of high quality sustainable housing that answer to the current and future needs of Canadians. Technologies, strategies, products and techniques that reduce resident’s ecological footprint. An ultra efficient and low environmental impact house, which provides the residents with a healthy living space.PowerPoint Presentation: Conserve energy and resources in the Canadian housing sector Create healthy and high quality housing, that reduces costs for residents Contribute to the restoration of the environment and to green-house gas reduction Encourage the blossoming of renewable energy and sustainable housing industries in Canada Determine the next generation of Canadian value-added export products that can compete on internationals markets Goal of the Equilibrium tm initiativePowerPoint Presentation: The VISION Home in Moncton, a 217m (2366 ft 2 ) house with attached garage, will be built by AlternaHome Solutions Inc. in partnership with the promoter, Synergy Urban Villages Inc. Maison Vision de MonctonPowerPoint Presentation: Main floor plan of the Vision HomePowerPoint Presentation: Second floor plan of the Vision HomePowerPoint Presentation: Geothermal pump What ? The house’s heating and cooling system. How ? The heath from the ground is sent to the pump to warm the house in the winter. The opposite process takes place in the summer (the heath from the house is transferred to the ground). Advantages: Low function costs; low maintenance; no need to buy combustibles; reduced green-house gas emissions; long life-expectancy (20 to 50 years); savings of up to 65% of electricity costs. Disadvantages : High initial costs; need to dig a large surface at considerable depth; space needed to store the pump. Technologies of the Vision HomePowerPoint Presentation: Photovoltaic (Solar Pannels ) What? This active solar powered system allows the capture, the storage and the distribution of the sun’s warmth. How? It included solar captors, a stocking mechanism and a distribution system. The sun’s rays are transformed and used to heat the house, warm the water and produce electricity. Advantages: maximizes the transmission of energy from the sun in winter to reduce or eliminate the need for other heating sources; allows to stock energy surpluses; reduced energy costs; relies on a renewable source; low maintenance; long- life expectancy (20 to 25 years guaranty, can last up to 40 years). Disadvantages: Elevated initial cost (8 000 $ to 10 000 $ per kilowatt installed). Technologies of the Vision HomePowerPoint Presentation: Passive solar What? Heat and light the house with the sun, thanks to the building’s orientation, the size of the surface covered with window, their type and orientation, the house’s thermic isolation and mass and the building envelope as well as the surface and placement of shaded areas. How? South-facing windows allow the sun’s rays to enter the house (no solar gain to the east and west, minimal gain to the north in summer and solar lost in winter). Choose insulated glazing windows, which are less emissive. Concentrate the rooms used more often to the south of the house and strategically place broad-leaved trees. Advantages: Reduces the energy needed for heating up to 40%; offers natural light; no need for specialized equipment. Disadvantages: Might be helpful to install eaves above windows to assure comfort in the summer. Technologies of the Vision HomeTechnologies of the Vision Home : Technologies of the Vision Home Sustainable and efficient building envelope What? Exterior coat that covers a building, separating the interior from the exterior and includes the carpentry, the air and vapour barriors , the insulation, the doors, the windows and the interior and exterior coverings. How? An envelope's efficiency depends on the chosen materials. Spray polyurethane foam, which is composed of recycled plastic, oil and soya residue, guaranties a sustainable envelop. Mineral wool, made from basalt (a volcanic rock), is incombustible, waterproof and et permeable to water vapour, while also being an excellent thermal and acoustic insulator. To fill cavities and attics, cellulose fiber, which is 100% natural and made from 80% recycled newspapers, is very efficient because it form a homogenous isolating cushion. Buildings’ thermic lossesTechnologies of the Vision Home : Technologies of the Vision Home Energy storage What? A system of batteries used to store energy surpluses produced by the solar panels, so that the energy can be used during the evening or on cloudy days. H ow? Lead acid deep cycle batteries are popular and made to resist discharges of up to 50% of their capacity. They have a longer life-expectancy than other batteries and have thicker internal plates to better resist charge fluctuations. Many different types exist. Advantages: Advantages differ depending on the type of battery. Some are less expensive while others require less maintenance and can be placed indoors. Usually, they have a 7 to 15 years life-span. Disadvantages: A full charge at least one per week is necessary to maintain the battery’s life-span; their efficiency diminishes with time; they need maintenance (protection from corrosion, water added regularly, sensible to the cold).Technologies of the Vision Home : Technologies of the Vision Home Rain water storage What? Stock rain water in order to use it at a later date and limit flooding during big storms. H ow? Rain water storage systems need a collecting surface, a vat and a pumping, filtering and distribution mechanism. Advantages: Constant water availability; less expensive if the vat is installed during the house’s construction. Disadvantages: Necessity of storing the water in a dark area, where the temperature is less than 17°C, to limit bacteria proliferation. In some cases, burying of the vat is required, to avoid freezing in the winter.Technologies of the Vision Home : Technologies of the Vision Home Personalized ( sur mesure ) energy management measures What? System that monitors, controls and allows to save energy. How? A centralized energy management system allows savings of up to 40%, by controlling heat and illustrating electricity use, while offering personalized programing. Digital timers allow energy savings of up to 15% by working around the residents’ schedule and habits. Digital thermometers can be programmed according to multiple preferences (ex: comfort vs. ecological). Load-shedding devices save energy by temporarily cutting less important circuits, in order to maintain the consumed energy at a given amount. Advantages: Reduces the environmental footprint and green-house gas emissions; reduces the dependency on fossil fuels; diminishes costs.Technologies of the Vision Home: What? Houses, being more and more air-tight for efficiency reasons, store pollutants and humidity inside. Therefore, ventilation systems can improve the residents’ health. How? Dual mechanism system: one that gathers and evacuates indoor air and the other that distribute fresh air from outside in the home. Both the interior and fresh air pass through the heat transfer module. The heat from the interior air is transferred to the entering fresh air, to pre-warm it. Technologies of the Vision Home Advantages: Uses little energy to maintain air at a superior level; recuperates 70 to 80% of the heat; diminishes green house gas emissions; renews all the air in the home in approximately three hours. High efficiency heat recovery ventilator ( HRV )Technologies of the Vision Home : Technologies of the Vision Home Solar water-heater What? System that allows the use of the sun’s energy to heat the water used in the home. How? Captors in a glass structure absorb the sun’s rays, which are then transported to a circuit containing water and antifreeze liquid (called primary liquid). This liquid is heated by contact with the captors’ tubes and is redirected towards a metallic vat containing sanitary water, where a thermic exchanger allows heat transmission. The primary liquid returns towards the captors, to be heating once again and the vat is left full of hot water waiting to be used by the residents. Advantages: Depending on regions, solar water-heaters can heat 40 to 70% of all the water used; reduced electricity costs. Disadvantages: The captors and the solar water-heater must be installed in close proximity to one another; the vat must be placed in a heated or well isolated room; a back-up system is recommended for use during long cloudy periods.

Suppression of sources of volatile organic compounds ( VOCs ; domestic chemical products or construction material), that degrades air quality in houses. How? Make judicious choices while deciding on materials during the construction of the house: only a few materials, such as glass, ceramic, metals and rock do not emit any contaminant. Take precautions, such as choosing products with little emissions or odours. Use water-based adhesives, coverings and paints. Limit furniture made of plywood or wood particles and avoid pine and cedar woods. Cover the insulation with a sheet of polyethylene. Advantages: Ensure a better air quality and can diminish health problems. Disadvantages: It can be difficult or expensive to obtain only materials with no or low VOCs .PowerPoint Presentation: Examples of sustainable practices Every inch is planted Egg, Switzerland : Greening near businessesPowerPoint Presentation: Examples of sustainable practices Freiburg, Germany: There is something planted everywhere Walking trails to get around the neighbourhoodPowerPoint Presentation: Examples of sustainable practices Switzerland : Garden in front of a house Montreal : Perennials are planted at the foot of treesPowerPoint Presentation: Examples of sustainable practices Grapes on the house and other fruits in the hedgesPowerPoint Presentation: Examples of sustainable practices Use of a low elevation and perennials for a reading corner Clothesline on a tripodBiodiversity conservation: Biodiversity conservation Traditional landscaping (grass, pavement, flower beds with annual and exotic flowers) does not encourage fauna and flora biodiversity A more diversified landscape will attract animals and insects Trees , shrubs and flowers offer food sources and habitats Some animals and insects are predators of insect pests Leave a large area untouched Biodiversity: the number and variety of organisms living on the planet (plants, animals, microorganisms, etc.), the communities formed by these species and the ecosystems in which they live.Biodiversity conservation: Biodiversity conservation Plant native species Plant species that attract other species (that will possibly eat pests) Plant a variety of species that will bloom in the spring, summer and fall Install other animal habitats on the property Pile of branches, dead leaves, rocks or logs Pond Birdhouses Leave grass clippings and dead leaves to make a shelter for insects and small animalsPlanting native (indigenous) species: Planting native ( indigenous ) species An indigenous species is adapted to the region’s: Climate soil conditions (water, nutrients, pH, etc.) insect pests and diseases Indigenous species adapted to the environmental conditions of the property help maintain it’s sustainability The use of other species adapted to the same conditions can give the same resultsPlanting native (indigenous) species: Planting native ( indigenous ) species Examples of New Brunswick native species : Canadian bunchberry Paper birch Witch hazel Rhododendron Serviceberry White cedar Wild strawberry Staghorn clubmoss Blue-bead lily Source : D.
