There is a tendency for Australian energy efficiency design guides to locate bedrooms of houses in temperate climates on the south, and concentrate on assuring solar access and thermal comfort in the living rooms, which are thus locatedon the north. The National Evaluation of Energy Efficient Houses or NEEHA research project (Ballinger, Samuels, Coldicutt, Williamson and D'Cruz, 1991) shows that occupants prefer to have winter sunlight and daylight penetration in bedrooms as well as living rooms. Indeed, the highest levels of discomfort recorded in each of the four city-regions/states are shown to be related to dissatisfaction with winter temperatures and sunlight penetration in bedrooms.
