What are the specific requirements for thermal performance under NatHERS for new single dwelling homes in a climate zone 6 area of Australia?

For new single dwelling homes in Australia's climate zone 6, NatHERS thermal performance requires a minimum 7-star energy rating. This is mandated by the National Construction Code (NCC). Achieving this involves considering various elements such as insulation levels for ceilings, walls, and floors, window performance (U-value and SHGC), appropriate shading, and thermal mass. The dwelling's orientation and layout also significantly influence its ability to minimize energy use for heating and cooling, which is crucial in climate zone 6 areas characterized by distinct seasonal temperature variations. Compliance is assessed through NatHERS-accredited software.
