  • NatHERS Certificate Guidance Factsheets

    The new NatHERS Certificate Guidance factsheets provide details on the features builders, certifiers and home owners should look for on a certificate. The NatHERS Certificate allows builders, certifiers and regulatory authorities to quickly confirm that the building has been built to the design on which the energy rating assessment is based. All certificates including the Non-Accredited certificate include information on the dwelling’s key design features, building materials and parameters used to generate its star rating.

  • NatHERS Accredited Certificate Samples

    Across Australia, all Nationwide House Energy Rating Scheme (NatHERS) star ratings are presented on a certificate. The shows key details about the dwelling, while the other pages give details about the building specifications and assessment assumptions. The certificate will be in one of two formats:

    1. If the certificate includes the NatHERS logo, it has been completed by a NatHERS accredited assessor. These certificates can be printed in colour.

    2. If the certificate does not include the NatHERS logo, it has been completed by a non-accredited assessor. These certificates can only be printed in black and white.

    They have been designed so that regulatory authorities and consumers can understand and easily check the home’s rating. The QR code, in particular, is key. When scanned, it takes the user to the original certificate that is stored on a secure website.

    The data from these certificates goes into the CSIRO Australian Housing Data portal (AHD). Furthermore, the certificates are actually the way much of the NatHERS Scheme is funded.
