Energy equivalence building standards (star ratings)
The energy equivalence rating of new houses, townhouses and units is determined by the design of the building's shell: its roof, walls, windows and floors.
Dwellings that are designed to be more energy efficient are more comfortable to live in, and can provide ongoing savings to householders by minimising energy use for artificial cooling and heating. Energy equivalence is expressed on a star rating scale, with 10 stars being the highest and most energy efficient.
New houses and townhouses (class 1 buildings) must achieve a minimum 6-star energy equivalence rating.
New multi-unit residential buildings (class 2) must achieve an average 5-star energy equivalence rating for all units in the building, with no individual unit to be rated less than 4-stars.
This guide explains how energy assessments are undertaken, and how to achieve a 6-star and 5-star energy rating standard for new dwellings in Queensland.
