(]() explores the role of design and construction on occupant comfort in hot weather. Such houses would also not meet current building regulations, as insulation has been required in new houses since 2003 (or earlier in some parts of Australia). This has led people to opening up their house, to stop them getting much hotter inside than outside.īut in temperatures of 40C and above, one could argue that both strategies (opening and closing) in an uninsulated house would result in very uncomfortable occupants. If uninsulated homes are closed up during a heatwave they would very likely become too hot. But the traditional timber and tin construction provides very little resistance to heat transfer. Such houses have great design features for cooling, including shady verandas and elevated floors. The traditional “Queenslander” house has long been seen as ideally suited for hot weather. To really stay cool when the heat is on, you also need to think about what type of house you have, and what its surroundings are like. Then, throw open the windows from late afternoon onwards, as long as overnight temperatures are lower outside than inside.īut our research shows that opening and closing doors, windows and curtains is just one of the factors at play. In a modern house the best advice is to shut up shop during the heat of the day, to keep the heat out. Listen to talk radio during a hot spell and you are likely to hear both views. Should you open or close your house to keep cool in a heatwave? Many people believe it makes sense to throw open doors and windows to the breeze others try to shut out the heat.
