Passive design features2

The design’s main aim is keep the home warm in winter. The main design features that can be used to achieve this are:

  • northern orientation for living room, with low-use rooms facing west, e.g. garages, bathroom and laundry
  • minimise east and west facing walls and windows
  • allow for good-ventilation—windows and doorways able to catch breezes
  • ceiling fans
  • wide eaves and awnings to shade eastern and western side of house in summer, northern eave provides shade in summer, but also allows winter sun inside
  • ensure roof space is well-insulated and ventilated e.g. whirlybirds and eave vents
  • insulated walls and floors
  • denser building materials, such as concrete and brick
  • high performance glazing in windows that are exposed directly to the sun e.g. low-e or tinted glazing on eastern and western aspects
  • well sealed doors and windows
  • if using air conditioning, ensure room is well-insulated and sealed
  • light coloured roof
  • well-located outdoor living area.
