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: the 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.
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.
This guide explains how energy requirements are assessed, and how to achieve a 6-star and 5-star energy rating standard for dwellings in Queensland.
