Understanding Energy Ratings
Learn how NatHERS energy ratings impact your home's efficiency, comfort, and value.
What is a NatHERS Energy Rating?
The Nationwide House Energy Rating Scheme (NatHERS) is Australia's national standard for assessing the energy efficiency of residential buildings. It uses a star rating system from 0 to 10 stars, where more stars indicate better thermal performance and lower energy consumption.
Why Energy Ratings Matter
Improved Comfort
Higher-rated homes maintain comfortable temperatures year-round with less heating and cooling
Lower Energy Bills
Better thermal performance means reduced reliance on heating and cooling systems
Increased Property Value
Energy-efficient homes are more attractive to buyers and can command higher prices
Environmental Benefits
Reduced energy consumption means lower greenhouse gas emissions
When Do You Need an Energy Rating?
- Building a new home or granny flat
- Undertaking major renovations or extensions
- Selling a property (mandatory in ACT, disclosure required in other states)
- Renting out a property (requirements vary by state)
