"A long-awaited increase in energy-efficiency requirements for new homes is
part of revised Australian construction standards taking effect on May 1. All
new homes must achieve a minimum 7-star whole-of-home energy rating from
October, following a six-month transition period.
It’s a crucial step in responding to the climate crisis and decarbonising
Australian society. It will also make our homes more affordable and comfortable
to live in, and improve our health and wellbeing.
These regulations affect the roughly 150,000 new homes built each year across
