Operation of the Nationwide House Energy Rating Scheme (NatHERS) is administered by the Commonwealth Government on behalf of all Australian governments. NatHERS activities are overseen by a Steering Committee, which includes representatives from the Commonwealth Government and all state and territory governments.

Under these arrangements, the Commonwealth Government, acting as the NatHERS Administrator, is responsible for:

  • accreditation of NatHERS software tools
  • approval and oversight of NatHERS Assessor Accrediting Organisations (AAOs)
  • Development and maintenance of NatHERS Protocols and procedures;
  • Management of upgrades to CSIRO’s Chenath calculation engine (which currently underpins all of the NatHERS software tools);
  • Communication with industry, government and consumer stakeholders; and
  • NatHERS development.

NatHERS provides a ‘measuring tape’ for rating residential building energy efficiency. How NatHERS is used for regulatory purposes, through the National Construction Code (NCC), is overseen by state and territory governments. 

The NatHERS Administrator and Steering Committee are expertly advised on technical issues and developments by the NatHERS Software Technical Advisory Committee (TAC)and provided with stakeholder and industry views on various aspects of the scheme by the NatHERS Stakeholder Consultative Group (SCG)

Further information on the Scheme's administration is contained in the NatHERS administrative and governance arrangements paper.

2016 NatHERS Governance and Operational Review

In 2016, as per the NatHERS Strategic Plan 2015-2018, the NatHERS Administrator engaged ACIL Allen Consulting to undertake an independent governance and operational review of NatHERS.

EEAT has finalised its response to the recommendations for the Governance Review on the possible future directions for NatHERS governance and operations.

In response to the Governance Review a stakeholder strategy has been developed including a service charter which outlines the NatHERS Administrator’s commitments to its stakeholders over the 2016/17 Financial year.


Processes for software and AAO accreditation are outlined respectively in the NatHERS Software Accreditation Protocol and Protocol for Assessor Accrediting Organisations. An updated AAO Protocol comes into effect on 1 July 2016 (Noting clause 4.5 – Continuing Professional Development will only come into effect when assessors next renew their annual accreditation after 1 July 2016).

NatHERS Strategic Plan

In August 2015, the Steering Committee released a Strategic Plan for 2015-2018. The Strategic Plan was developed in collaboration with stakeholders to establish a clear and focused strategy for progressing NatHERS. The Strategic Plan outlines the context in which NatHERS operates, the overall vision for NatHERS, its core mission and values, and actions to be achieved out to 2018.

In November 2016, the Steering Committee released an update to the NatHERS Strategic Plan 2015-2018. This update does not seek to re-evaluate the Strategic Plan, but rather acknowledge developments since the original Strategic Plan was released in 2015. A new Strategic Plan will be developed for 2018.

Following the first year of the Strategic Plan an annual report was developed measuring the success of the programme in relation to the goals set.

The NatHERS Administrator is formalising a number of key performance indicators (KPIs) to accurately track the success of the scheme in future annual reports. While the majority of outcomes, goals, targets and measures are now set, the NatHERS Administrator will be working with key stakeholders to finalise a number of outstanding measures and targets over the next 12 months.

The National Construction Code

Obtaining a NatHERS rating at the required star level is specified in the National Construction Code (NCC) as one of the ways of demonstrating compliance with the energy efficiency (thermal performance) requirements for new houses and apartments.
