Assessors must use Technical Note (version June 2019) for all NatHERS assessments commenced from 1 June 2019. For NatHERS assessments commenced prior to 1 June 2019, assessors may use the requirements outlined in Technical Note 1 (version 1.2 – 2014) or Technical Note (version May 2019). If the Certificate is produced after 1 June 2019, but the assessment was commenced prior to 1 June 2019 and Technical Note 1 (version 1.2 – 2014) or Technical Note (version May 2019) was used, this should be noted in the ‘additional notes’ section of the NatHERS Certificate.
To become a NatHERS accredited Thermal Performance Assessor you must obtain accreditation with an Assessor Accrediting Organisation (AAO).
The two AAOs under the NatHERS protocol, the Building Designers Association Victoria (BDAV) and Association of Building Sustainability Assessors (ABSA) are able to accredit assessors who have fulfilled the requirements of accreditation.
New entrants to the thermal performance assessor market must complete the Certificate IV in NatHERS Assessment to be eligible for accreditation.
