Coatesville Passive Solar House in Rodney, North of Auckland, New Zealand is a series of stacking saw tooth roofs designed to capture every possible bit of sunlight during winter and naturally exhaust warm air through a series of clerestory windows during summer. The family house design is a bit like an old saw tooth shaped factory roof- but smarter! The home is 270sqm situated on a 2.5 acre property with bush and valley views.
The house relies on exposed insulated concrete slabs and large insulated vertical precast concrete walls for optimised passive solar gain and heating during winter time. The roof shapes and windows function as large clerestories allowing a natural stack effect to cool down the interior and naturally ventilate the bedrooms and living spaces over summer time.
