Welcome to Year of the House. This blog follows the construction of an energy efficient home in a rural location near Ottawa, Ontario, Canada. This house is designed using energy saving concepts such as;
- Passive solar design (large south-facing glazing for solar gains and minimal east/north/west facing glazing used only for sufficient natural lighting, also no outside shading on south that could prevent the use of solar gains).
- Acquire local solar angle data to design overhangs for south-facing glazing.
- Thermal mass to retain solar gains (concrete floors).
- Super-insulated walls, foundation and roof. This house uses a double wall system filled with cellulose fibre insulation.
- Airtight/sealed envelope (no cold bridges such as steps in walls and dormers).
- Floor plan design to ensure that utilization areas are compact for example place bathrooms next to or above kitchen, place laundry facilities near bathrooms/kitchen.
- Mechanical heat recovery ventilation.
- Energy conservation such as water saving taps, low flow toilet and energy star appliances.
- Using locally produced materials as much as possible.
