The minimum standards for thermal comfort of new homes will be increasing from 6 to 7 stars out of 10 (NatHERS ratings), under changes to the National Construction Code 2022 (NCC 2022).
In addition, a new Whole of Home annual energy use budget will be introduced for fixed appliances (heating and cooling, hot water systems, lighting, pool and spa pumps) with the potential to offset with rooftop solar.
There will also be new readiness provisions that will make it easier to install:
- electric vehicle (EV) charging
- solar PV systems
- batteries in apartment buildings and some non-residential buildings to reduce the cost of future retrofitting.
