Janine’s passive solar home features an exposed concrete slab facing northwest, narrow build to increase air exchange, awning and sliding double-glazed windows on opposite walls for air flow. All living and bedrooms have two-way ceiling fans for winter and summer settings.
Heating is via a first-storey-installed Coonara 5-star rated gas log fire and 15% of heat flued to downstairs via a fan. Heated air is also circulated with winter setting on ceiling fans. A Ventis ventilation system extracts heated air from the roof cavity and at a single ceiling space at the top of the stairwell to purge hot air as it rises in summer to outside. During autumn and spring particularly, heated air in the roof cavity is pumped back into the house as supplementary heating through a medical-grade filter.
The home has been designed to have the living areas in the treetops and face north- north/west. The house has been zoned with doors into living areas both on ground floor and first floor. The doors help to control the unwanted movement of air throughout the house.
