Software for Energy Rating

2nd Generation Tools

Accredited 2nd generation NatHERS software tools
  • AccuRate (version 1.0)
  • BERS Professional - granted provisional accreditation 8 November 2007
  • FirstRate 5 - granted provisional accreditation 31 August 2007


AccuRate was developed by CSIRO and is the 2nd Generation successor to the NatHERS software. It provides a sophisticated method of measuring the energy performance of homes.

BERS Pro meets the BCA second generation protocols. It has undergone NatHERS/AGO accreditation.

BERS Pro incorporates a state of the art 2-D graphical user interface to the CSIRO thermal simulation engine, maintaining a balance between speed of use and accuracy.

FirstRate 5

FirstRate 5 is based on the new AccuRate energy rating software that was released into the market in 2006. The new look FirstRate5 includes the AccuRate calculation engine plus a host of new features including:
  • the ability to zone the house according to how each room will be used
  • the ability to rate up to 10 stars
  • the full range of AccuRate climate zone (69 in Australia, and 11 in Victoria, instead of 5)
The rating is independent of the size and type of housing. This means that all housing has the potential to achieve a good energy efficiency rating.
Other rating tools:


A regulation of the NSW Government that ensures that any new building is designed to meet the environmental outcomes of 40% less water consumption and 25% reduction in energy usage. Introduced by the NSW Government, BASIX, the Building Sustainability Index, ensures homes are designed to use less potable water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for house and units.

(The Western Australian Government has chosen not to implement BASIX at present.)
The Window Energy Rating Scheme (WERS) rates the heating and cooling energy performance of windows in residential buildings anywhere in Australia.

Australia's guide to environmentally sustainable homes

Rating tools should be designed to assess the environmental impact of interior fit-out of buildings. A green fit-out may include features such as access to natural light combined with efficient artificial lighting, energy and water conservation features, waste management, fit-out items with low emissions and reduced environmental impacts, and timber from sustainable forests.
