Main Features and Benefits of 6-Star Rated Homes

01 January 2020

Home Energy Rating System (HERS) index shows your house’s thermal performance. In other words, the rating describes required for your home to maintain a comfortable temperature. A higher HERS index shows that your home’s indoor temperature is comfortable and doesn’t require a lot of energy to maintain. Generally, the less energy a home requires, the higher the value of the star rating it will have.

NatHERS is the body that rates a home’s energy efficiency in Australia and it uses several parameters. The body has a software program' which estimates the potential energy use of a home. Through this rating, people can easily understand the amount of energy that their homes use for heating and cooling. This enables them to make smart choices and save money on their energy bills.

In most states of Australia, a NatHERS 6 star energy rating is the minimum requirement your home should meet to get the building permit.

Features of 6-Star Rated Homes

Effective Insulation
