Energy Efficiency Assessors

Design Matters National is the largest organisation representing NatHERS Accredited Energy Efficiency Assessors (EEAs) in Australia. 

These Accredited professionals play an integral role in facilitating a more sustainable outcome in combination with design professionals to improve the energy efficiency of commercial and residential buildings throughout nationally.

Design Matters National is a NatHERS (Nationwide Home Energy Rating Scheme) Assessor Accrediting Organisation recognised by the Department of Climate Change, Energy, the Environment and Water and maintains optimum Accreditation education programs for EEA members.

The EEA dedicated helpdesk, referred to TechLink is available for members requiring assistance to navigate the technicalities of regulatory interpretation and best practice modelling to ensure informed and correct energy assessments. The TechLink widget can be found to the lower right of your screen.

We work closely with federal and state governments to advocate for, and ensure our members are supported to follow best practice and industry regulations. 

EEAs will find the following go-to resources helpful in their professional practice.

Coming into effect from 1 October 2023 will the the NatHERS Technical Note 2022. NatHERS have also released the Whole of Home Guidelines to be read in conjunction with the NatHERS Technical Note 2022. An updated version of the NatHERS Handbook to support the NatHERS Technical Note 2022 is underway.

National Construction Code Housing Energy Efficiency Handbook 2023

The Housing energy efficiency handbook assists in understanding the energy efficiency provisions in NCC Volume Two that apply to houses. 

It addresses issues in generic terms and is not a document that sets out specific compliance advice for developing solutions to comply with the requirements in the NCC. This handbook is intended to guide readers in developing solutions relevant to specific situations in accordance with the generic principles and criteria.
