What are the specific thermal performance requirements under NCC 2022 for new detached homes in climate zone 5 in Australia?

NCC 2022 mandates a minimum NatHERS rating of 7 stars for new detached homes in climate zone 5, representing a significant uplift from the previous 6-star requirement. This necessitates improved insulation levels, double glazing as standard, and careful consideration of thermal bridging and air movement to achieve the enhanced energy efficiency targets.
