On 1 July, new Building Sustainability Index (BASIX) energy targets will come into effect. Part of the government’s initiative to reduce energy use and greenhouse gas emissions, these changes will improve the energy efficiency of homes in NSW, resulting in lower utility bills for residents, and lessen impact on the environment.

New homes, built better

Part of the Development Application (DA) process for homes in NSW, BASIX ensures proposed designs are sustainable. Currently, homes use approximately 17 per cent of the state’s total energy consumption. With 1.8 million new homes expected to be built over the next 40 years, it’s important these are designed in a way that maximises energy efficiency.

Outline of changes

Energy targets for houses and low-rise units will increase by approximately 10 per cent, and by 5 per cent for mid and high-rise units. Thermal comfort heating and cooling settings will also change.


These changes were announced in A Draft Plan to Save NSW Energy and Money, which was released by the Minister for the Environment in October 2016.
