NatHERS – A Rating System for Thermal Performance of Buildings

The Nationwide House Energy Rating Scheme, or NatHERS, uses a 10-star rating system which is able to easily assess the thermal performance of buildings within Australia. Though a NatHERS certification is required for all new developments with multiple dwellings, it is essential for all residents to obtain an assessment to be able to easily evaluate the thermal assessment of their development.

Why is NatHERS assessment required in my house?

NatHERS as outlined above is the Nationwide House Energy Rating Scheme which is able to evaluate the thermal performance of any dwelling. Though this may seem irrelevant and unnecessary when outlining the overall performance of the building, is it a necessity to get a NatHERS assessment in order to ensure a sustainable future for our environment.

Not only this, but NatHERS is essential when obtaining a BASIX assessment. BASIX is a NSW Government initiative striving to improve the environmental sustainability. It comprises of three factors: water, thermal and energy. The thermal component of BASIX can be easily completed through a NatHERS assessment with its thorough, accurate and flexible approach to addressing thermal performance.

Thus, a NatHERS assessment is required not only to contribute towards a sustainable future for the environment but also as a necessity under the BASIX initiative led by the NSW Government.

Ingredients of NatHERS assessment

A NatHERS assessment can be obtained by a specialised company that has NatHERS Accredited Software which can be used to determine the thermal efficiency of your home. Within the assessment, each resident will be provided a copy of the key design features, the building materials and the scope used to generate the dwelling’s star rating.

The star rating, also known as the Energy or Thermal Efficiency star rating, is an accurate indicator of the level of heating or cooling your building requires to not only make you feel comfortable, but to ensure that it doesn’t have a detrimental impact on the environment. By following the recommendations and guidelines that will be included in your report, you will also be on the path of having lower energy expenses, by using the appropriate amount of electricity.
