All new Development Applications require a NatHERS Certificate to show they meet energy efficiency requirements of the National Construction Code.

NatHERS is a star based energy rating system which uses computer simulation software to estimate the potential heating and cooling energy requirements of a home based on its design and construction. A minimum of seven stars is required in NSW with other states following soon.

The NSW required BASIX accepts NatHERS rating results which are prepared by an accredited assessor using accredited software for the thermal performance component of the certificate.

Preparing an assessment

When preparing an assessment, we’ll discuss your assessment needs, from achieving the minimum compliance level to ensuring a home with high thermal performance. We’ll then run a computer simulation of your home using the latest thermal performance software. We’ll provide you with recommendations for either meeting your energy requirements or maximizing thermal performance.

Once you’re satisfied, you’ll receive a NatHERS Certificate and a stamped set of your plans showing the star rating and energy details. You’ll then submit these documents to council with your development application.
