FirstRate5 house energy rating software (click here)

FirstRate5 v5.2.0 (3.13) is now available as a free download from Version 5.2.0 (3.13) contains a number of new features and enhancements. FirstRate5 is an easy-to-use interactive tool with a graphic user interface that enables designers and thermal performance assessors to generate energy ratings for a home by tracing over floor plans. The software integrates the AccuRate calculation engine to estimate the annual heating and cooling energy and can be used to rate an existing design or as an interactive tool to optimise the design beyond compliance.


The BERS Pro Plus House Energy Rating Scheme is a Nationally accredited Home Energy Rating System. The BERS Pro computer program is the centre of the thermal simulation process. It is used to simulate the thermal performance of Australian houses in climates ranging from Alpine to tropical.

BERS is a Home Energy Rating Scheme that can be used to assign a star rating to a house within a particular climate type.

Other rating tools:


BuildingSustainability Index BASIX , a regulation of the NSW Government that 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 Window Energy Rating Scheme (WERS) rates the heating and cooling energy performance of windows in residential buildings anywhere in Australia.

(The Western Australian Government has chosen not to implement BASIX at present.)

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.
