The clients demolished a bungalow close the lake Ontario in Oakville and constructed a new modern home on the same footprint. The many mature deciduous trees meant that south and west facing trees could be shaded in summer but allow for passive solar heating in winter.
Green Design Parameters
· 2x6 Construction with R22 batt and four inches of exterior foam below stucco to prevent cold transfer through the studs
· Centre “Open to Above” spine used to increase heating and cooling efficiency: There are two Mechanical Rooms. One room is in the basement and one room at the roof level. Each Mechanical Room has a small natural gas furnace and the rooftop Mechanical Room contains a micro air conditioner.
· In the summer the cold air is expected to drop down through the house from the rooftop system.
· In winter the basement furnace will be activated more frequently because hot air rises and the 2nd floor bedrooms will be heated via convection airflow.
· Hot air is captured at the highest ceiling level in the house that is the roof lite extending above the 2nd floor level.
· Operating skylights at the highest ceiling level allows for natural convection airflow in the summer
· The east side of the house faces Lake Ontario and East / West windows provide natural breezes in summer.
· Deciduous trees on the west side provides shading in summer
