Passive design features2

This climate zone’s variability presents some complex design issues to be considered given its seasonal extremes. The main passive design features that can be used to achieve this are:

  • northern orientation for living room, with low-use rooms facing west eg. 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 eg. whirlybirds and eave vents
  • insulate walls
  • lighter building materials, such as timber and metal with some denser materials for winter warmth, such as concrete and bricks
  • high performance glazing in windows that are exposed directly to the sun e.g. low-e or tinted glazing on eastern and western aspects
  • if using air conditioning ensure room is well-insulated and sealed
  • light coloured roof and walls
  • well-coloured outdoor living area.
