New homes built to NCC 2022 7-star standards typically incur an average additional cost of $4,300, offset by annual energy bill savings of around $326. States like NSW have seen increased double glazing use, while Queensland achieved compliance with more modest cost increases by optimising window design and maintaining existing home sizes, often without requiring double glazing. These approaches influence window and door specifications for energy performance.
