Energy Rating

Nationwide house energy rating scheme logoIn Australia, all new residential buildings are subject to the construction regulations contained within the National Construction Code (NCC).

The stated objective of the energy efficiency requirements is to reduce greenhouse gas emissions and various methods are available to designers to demonstrate compliance with the requirements. The most common method utilised is the modelling of a proposed design in specialised software. Various software tools are available, but all need to be accredited under the Nationwide House Energy Rating Scheme (NatHERS) which is administered by the federal Department of the Environment and Energy.

Energy efficiency requirements for residential buildings were first introduced into some jurisdictions in Australia in 2001 and were then adopted into all Australian States and territories in 2003. It is estimated that 80% of new residential buildings in Australia use NatHERS accredited software as their means of demonstrating compliance with the NCC.
