Spring Garden House
North York Passive Solar Eco-Home
This replacement home in North York is designed to bridge the gap between its traditional neighbours, and the contemporary preferences of the clients. Its roof line is broken to create a contemporary re-thinking of a traditional house shape, and to facilitate passive ventilation and natural daylighting into the middle of the home - the form follows the function. A ventilated solarium on the south facade is the sustainable engine of the home. In the winter, it captures solar radiation to warm the house. In the summer, it both shades the home and produces negative air-pressure using stack-effect principles to passively ventilate the home.
On a -20°C winter day the homeowner has measured a temperature of 14°C inside the solarium – with no heating system!
This 34°C temperature differential, fuelled only by the sun, along the south wall of the house, really cuts down on the work that the heating system needs to do inside the house.
