About the Nationwide House Energy Rating Scheme (NatHERS)
What is NatHERS?
NatHERS provides a framework that allows various computer software tools to rate the potential energy efficiency of Australian homes. NatHERS defines the minimum set of information that must be used by all software tools.
NatHERS facilitates consistent and repeatable ratings irrespective of the commercial software tool selected, and ensures that homes in all regions are treated fairly in their rating. NatHERS enables homes of good practice for each local climate to receive a similar rating, even though each building will be subject to widely different climatic conditions.

NatHERS defines a fair and transparent process for competing software tools to be accredited. Accredited tools are eligible to use the HERS logo in a responsible way, and advertise their association with NatHERS.
NatHERS provides for energy rating assessors to be registered by Assessor Accrediting Organisations.
NatHERS is an initiative of Commonwealth, State and Territory Governments through the Ministerial Council on Energy. The role of NatHERS Steering Committee is held by the Energy Efficiency Working Group (E2WG) of the Ministerial Council on Energy and the role of NatHERS National Administrator is held by the Department of the Climate Change and Energy Efficiency on behalf of E2WG.
Further information on the Scheme's administration and development is contained in the Nationwide House Energy Rating Scheme administrative and governance arrangements paper.
