Good orientation of your home in relation to the sun, can make your home more energy efficient, cooler in summer and warmer in winter. This makes the selection of your allotment, the house design and siting of the house on the lot, all critical elements in your future enjoyment of your home.
A booklet available on Government’s Your Home website, authored principally by Caitlin McGee from the University of Technology, Sydney with contributions from the late Dr Chris Reardon and building designer, Dick Clarke, sets out in detail all the issues associated with maximising the energy efficiency and therefore your enjoyment of your home.
The authors set out the range of issues in great detail making the booklet a virtual must read for anyone contemplating building a new home. The key issues however can be summarised in the following bullet points.
- Consider your climate – location, prevailing winds, temperature range, level of humidity
- The aim of good solar orientation is to fine the “optimum balance between capturing sunlight and capturing cooling breezes” to assist in your heating and cooling needs.
- North orientation is desirable in most Australian situations, with perhaps the exception of the tropic north.
- The best sites will allow north-facing daytime living areas that flow to outdoor north-facing open spaces.
- For small lots, the solar access goals will most likely be achieved on north-south lots.
- If north-south lots have the front to the north, consider living areas at the front of the home, opening to a private courtyard, like the plan below from one of our preferred builders, Ausbuild.
- East-west sites should allow for living and open spaces to the north.
This is a very brief summary and there are many other aspects to consider such as how to capture breezes, shading open areas, where to locate rooms other than living areas, best garage location, allowing for over-shadowing, clothes drying and others.
