The Green Dream Home features an exterior design intended to blend with the architecturally controlled style of the neighbourhood. The south sloping site allows for large windows to capture the view and solar energy, and for outside access to both the main and lower floors. The 117 m2 (1,258 sq. ft.) main floor includes an open-concept living room, dining room and kitchen, den or bedroom, bathroom with sink, toilet and bathtub with shower, and laundry with drying closet. The master bedroom, bathroom with sink, toilet and large ‘European’ shower, walk-in closet and small loft area are on the 66.9 m2 (720 sq. ft.) second floor. The 117 m2 (1,258 sq. ft.) basement walk-out floor contains a recreation room, bedroom with walk-in closet, bathroom with sink, toilet and bathtub with shower, mechanical and electrical room, storage, and a wet bar. An unfinished attic space above the garage is accessible for use as storage space and could be developed to expand living space. The home can be adapted to accommodate a family, empty-nesters, or a home office, thereby attracting a wide range of prospective buyers.
The total annual energy requirement for the home is predicted to be a little less than the on-site annual production from renewable energy sources: passive solar space heating, active solar water heating and photovoltaic (PV) electrical generation. In addition, a ground source heat pump (GSHP) and drain water heat recovery (DWHR) device reduce energy requirements for space conditioning (heating and cooling) and hot water. The home benefits from its excellent solar access and optimal solar orientation. Insulated concrete forms (ICFs) were used to construct the well insulated, air-tight building envelope which, with the other energy efficiency features, are predicted to reduce the household energy requirements, on a per m2 (sq. ft.) heated floor area basis, to 15% of the energy requirements for a typical Canadian home.
