How do NCC 2022 energy efficiency changes impact residential new build designs in Queensland?

The NCC 2022 energy efficiency changes, particularly the move to a 7-star NatHERS rating, compel Queensland residential new builds to integrate enhanced thermal performance through superior insulation, glazing, and passive design strategies like increased shading. Furthermore, the introduction of a whole-of-home energy budget necessitates a holistic design approach, factoring in the efficiency of fixed services like hot water and lighting to ensure overall energy consumption targets are met, thereby influencing material and appliance specifications from the outset.
