Will double glazing give me a higher energy star rating?
All new homes, home renovations, alterations and additions need to comply with the Energy Efficiency provisions in the National Construction Code (NCC) which includes the option of complying with the 6 Star Standard.
The 6 Star Standard applies to the thermal performance of a home, renovation or addition. New homes are required to include the installation of either a solar hot water system or a rainwater tank for toilet flushing.
A 6 Star energy efficiency rating applies to your home’s building envelope – its roof, walls, floor and windows. Double glazing will help you achieve this energy rating.
6 Star requirements also include efficiency standards for lighting but not plug in appliances.
Minor building works, not requiring a building permit, will not be affected by the regulations. However, all new homes and building projects involving home extensions and major renovations will need to comply with Energy Efficiency provisions of the (NCC).
Meeting 6 Star compliance is not difficult: it’s about good design, particularly at the planning stages. So talk to your building practitioner early to take advantage of the benefits, such as increased comfort, saving money on energy bills and making your home more resilient to climate change. Carefully selecting your site so your home’s orientation takes advantage of solar energy can add up to 1 Star to the rating.
6 Star homes are projected to use 24 percent less energy through heating and cooling compared to 5 Star homes. This will see owners with 6 Star homes potentially saving a further $100 off their energy bills each year. This is only an average saving, with residents who use the energy features in their home wisely saving even more.
Consider design options such as low-e glass that go beyond minimum regulatory requirements: it will pay in the long run and improve the value of your home.
