Heating and cooling homes adds cost to energy bills and impacts the environment. The amount of energy needed to stay warm in winter and cool in summer can easily be reduced by the good design and construction of our homes.
Assessing a building's thermal performance at design stage can identify simple, economical ways to make it more comfortable and save energy.
NatHERS enables the design of a home to be assessed by skilled professionals using sophisticated computer modeling programmes to improve the quality of design and achieve building approvals.
NatHERS sets national standards for professionals offering assessment services as well as the software they use.
February 2014 - NatHERS Benchmark study 2013
The NatHERS Benchmark study engaged 344 NatHERS assessors who volunteered to assess one of four randomly-selected house plans in their chosen NatHERS software tool. The study took place from May to December 2013 and was undertaken to establish a baseline against which future improvements in the NatHERS scheme can be developed and evaluated.
Thank you to all assessors who participated in this important project. Step-through answers for one of the house plans can be found by logging into NatHERS worked examples
23 October 2013 - Qualification for NatHERS assessors update
New assessors will be required to be qualified with the Certificate IV in NatHERS Assessment from January 2014.
All existing assessors will be required to upgrade their skills to the Certificate IV in NatHERS Assessment by 1 July 2015. Appropriate Registered Training Organisations who may deliver the course can be found here.
The new interactive NatHERS Climate zones map now makes it easier to see in which particular climate zone your street or building site is located in. Topographic details and a brief summary of key climate information are also included for the first time. View the interactive map
The training resources to complement the Certificate IV in NatHERS Assessment have been developed to assist Registered Training Organisations with consistent delivery of the Certificate IV. The resources have been developed with expert guidance from both NatHERS Assessor Accrediting Organisations, and consist of a Learners Guide, Trainers Guide, Assessment Kit and Recognition of Prior Learning Guide. The resources are available for download - free of charge - by registering via the Construction and Property Services Industry Skills Centre website.
The NatHERS logo has been registered as a Trade Mark under the Trade Marks Act 1995. This registration will provide the NatHERS National Administrator with greater powers to address illegal use of the logo. Revised Guidelines for using the NatHERS logo (April 2013) have been issued.
A report on the study of the effect of ground heat transfer on the thermal performance of buildings has been released. The findings will help improve the Chenath calculation engine, which underpins the three software tools accredited under the Scheme.
This note provides information about the new Certificate IV in NatHERS Assessment. It aims to answer questions that may be raised by existing NatHERS assessors, people interested in becoming assessors, registered training organisations and other interested parties.
Nationwide consultations with industry, assessors, state and territory governments and accreditation bodies has been undertaken through the Construction and Property Services Industry Skills Council (CPSISC) in development of the new Certificate IV in NatHERS Assessment. The new qualifications will be presented for endorsement at the quarterly meeting of the National Skills Standards Council (NSSC) on 5 September 2012.
The Nationwide House Energy Rating Scheme (NatHERS) - Software Accreditation Protocol, June 2012 (Protocol) was prepared by the NatHERS National Administrator with the assistance of the state and territory building energy efficiency policy agencies and the Australian Building Codes Board. It was approved by the NatHERS Steering Committee (Energy Efficiency Working Group, E2WG) of the Select Council on Climate Change and came into effect on 26 June 2012.
This single Protocol combines and replaces the Procedure for Accrediting Software under the Nationwide House Energy Rating Scheme (April 2007 and 2011) and the Australian Building Codes Board Protocol for House Energy Rating Software (Version 2005.1).
