FirstRate5® house energy rating software

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.

Extension of transition period for FR5 v5.2.9 (3.13)

by FR5 | Mar 04, 2019
Sustainability Victoria (SV) has decided to extend by seven weeks the transition period during which both FR5 v5.2.9 (3.13) and FR5 v5.2.10 (3.13) files will automatically calculate on the FirstRate5 website.

This has been done to allow users more time to adjust to the new features contained in FR5 v5.2.10 (3.13) and upgrade existing project files.

Extended transition arrangements for FR5 v5.2.9 (3.13)


Until 24 April 2019 (5pm) a transition period will be in place. During this period both v5.2.9 (3.13) and v5.2.10 (3.13) files will automatically calculate on the FirstRate5 website. Please note the following:                                               
  • All project files created using a version of FR5 v5.2.9 (3.13) will be calculated using the v5.2.9 calculation engine when uploaded to the FirstRate5 website.
  • All project files created using a version of FR5 v5.2.10 (3.13)  (i.e. v5.2.10 or v5.2.10a) will be calculated using the v5.2.10a calculation engine when uploaded to the FirstRate5 website.

After 24 April 2019 (5pm) v5.2.10 (3.13) files (i.e. v5.2.10 or v5.2.10a) will continue to automatically calculate on the FirstRate5 website, however v5.2.9 (3.13) files will calculate by special request only.
