The NatHERS Assessor Handbook has been developed by the NatHERS Administrator in conjunction with industry experts.
It is designed to help assessors navigate the NatHERS assessment process, by describing how assessments are to be conducted, including the mandatory and recommended steps of the process.
The handbook provides additional guidance to support the NatHERS Technical Note. It presents information that can assist assessors, regardless of which NatHERS accredited software tool is used. For guidance on undertaking activities in a specific software assessment tool, assessors should contact their software tool provider or consult their relevant software tool manual.
A Guidance Note for assessors undertaking Whole of Home assessments is also available. In the future, the Guidance Note will be incorporated into the NatHERS Assessor Handbook.
