What are the specific NatHERS star rating requirements for new detached homes built in Queensland post-NCC 2022?

Post-NCC 2022, new detached homes in Queensland must achieve a minimum 7-star NatHERS rating, a significant uplift from the previous 6-star requirement. This change, effective May 1, 2024, as per Queensland's adoption of the NCC 2022 energy efficiency provisions, aims to reduce energy consumption for heating and cooling. Additionally, homes must meet a whole-of-house energy budget, incorporating the energy use of fixed appliances like hot water systems and lighting. This holistic approach ensures greater thermal performance and operational energy efficiency across the dwelling, aligning with national sustainability targets.
