New NatHERS Whole of Home rating
Energy and Building Ministers have agreed to a major change in energy efficiency ratings for Australian homes that will help cut their ongoing costs and put them on the path to net zero emissions.
For the first time, energy ratings for the whole home will be provided adding the energy performance of major appliances such as hot water, heating and cooling, pool and spa pumps, as well as solar energy generated onsite.
Adding to the current star rating assessment out of ten, the new rating will be a separate rating out of 100. It considers energy used for heating and cooling, and appliances, minus energy generated from solar panels.
This builds a useful snapshot of energy costs as well as greenhouse gas emissions.
Assistant Minister for Climate Change and Energy Jenny McAllister said the changes will mean more homebuyers will have access to energy efficient and comfortable homes that cost less.
“With more than 150,000 houses built every year, these efficiency measures will help reduce energy demand which is vital to support the economy’s transition to net zero,” Assistant Minister McAllister said.
