Orientation is the positioning of a building in relation to the sun’s path and wind patterns. Having good orientation can increase the energy efficiency of your home, making it naturally comfortable, while lowering energy costs.
Good orientation, combined with other energy efficient features such as high performance insulation, can greatly reduce or even eliminate the need for artificial heating and cooling.
Because Australia is in the southern hemisphere, homes with a north facing orientation are desirable because the sun’s high position in summer allows you to easily shade north facing walls and the ground near them with eaves, while the sun’s low position in winter maximises sun penetration potential helping to warm your home for free.
