GARDEN SUITE ALGONQUIN COLLEGE ECO DESIGNADETOLA S., MEGHA R., SRINATH N.
SITE A Garden Suite on the site of Algonquin College in Ottawa. The Garden Suite will accommodate a married couple and one child. At least one of the adults is a student. In addition to being a fully functional Garden Suite, this is intended to be a demonstration project to show the general public the benefits of sustainable design.

SITE ANALYSIS
SUSTAINABLE CHOICES DENIM INSULATION: It comes in batt form like fibreglass and stone wool. It performs better than fiberglass during high winds and at low temperatures; it is extremely effective for sound absorption and thermal performance; easier installation than fibreglass; no protective gear needed; it contains 10% boron-based fire retardant (a natural non-toxic mineral),and it's resistant to fungus, mold, and pests. R value: 3.6 per inch
20” WALL FRAMING: The wall frame is composed of 2x6 stud and 2x4 stud held together by a series of plywood gusset plates. By building with these wall trusses, we end up with a double stud wall with an interior structural element, and the whole assembly goes together in one shot. With wood fibreboard or OSB interior insulation and 20" deep cavities for filling with Cotton batt(denim) R value: 3.45 per inch
TESLA SOLAR ROOF: Made of quartz, Will be offered in Tuscan glass tile, slate glass tile, textured glass tile and smooth glass tile, Uses Powerwall battery (lithium ion rechargeable battery) Lifetime warranty, Strong and durable Tiles can be adjusted as per energy need. $24.50 per square foot Generates 5.3w/sqft
SUSTAINABLE CHOICES WINDOW GLAZING AND FRAME: Triple insulating glass (1/2" air spaces) Use of wood frame for windows Operable windows for natural ventilation, Airtight, Highly insulating, Available with high SHGC glass Solar heat gain is influenced by the glazing type, the number of panes, and any glass coatings. Solar heat gain of glazing ranges from above 80% for uncoated water-white clear glass to less than 20% for highly reflective coatings on tinted glass. R value: 3.23
ENERGY RECOVERY VENTILLATION: (ERV) is the energy recovery process of exchanging the energy contained in exhausted building or space air and using it to precondition the incoming outdoor ventilation air. In warmer seasons, the system pre-cools and dehumidifies while humidifying and pre-heating in the cooler seasons.
GRASS PAVERS: Turf pavers are essentially permeable pavers that are proven to be friendly to the environment. Their design lets storm water to be recycled instead of just flowing straight to waterways and drainage systems. This effectively cuts irrigation requirements
SUSTAINABLE CHOICES CEDAR WOOD EXTERIOR FINISH: Cedar wood sidings and shingles are used for exterior finish and roof covering. The wood is from FSC certified forests. R value: 1.33
HEMP PLASTER: Lime Hemp Plaster is made from a high calcium lime blended with hemp fibres and a pozzolan to aid the set. The addition of hemp fibres not only improves the strength and flexibility of the product, it also increases the thermal properties of the plaster and so is an excellent way of adding some insulation to your wall. R value: 2.08
RAINWATER HARVESTING: Rainwater is collected from the roof through gutters and filtered to the tank to be used for household purposes. 5000g tank is installed Average family uses 500g per day and so if in the month of April with 150mm rainfall, we can store 3170 gallons.
RADIANT FLOORING: Hydronic systems use water or a mix of water and anti-freeze such as propylene glycol as the heat transfer fluid in a "closed loop" that is recirculated between the floor and the boiler. Various types of pipes are available specifically for hydronic underfloor heating and cooling systems and are generally made from polyethylene.
