Alright - so none of these things are really secrets - but they may as well be, given how little attention's given to energy efficiency measures in so many Australian homes. Little details like double glazing, good insulation, sensible eaves, proper ventilation and even the colour of your roof can have a huge impact on your electricity and gas bills.

Not many people realise this, but energy star ratings for homes are actually allocated based on the design, rather than the finished product. A badly put together six star home isn't really a 'six star' home at all - and neither is a good one if you don't use it properly.

If you're dead serious about energy efficiency, choose a reputable builder who shares your commitment, and really get to know your home properly!
