FR5 Software

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.

Expiry of FirstRate5 v5.1.11c – 30 April 2016

by FR5 | Apr 20, 2016

The NatHERS National Administrator has informed Sustainability Victoria that the short-term accreditation of FirstRate5 v5.1.x will expire on 30 April 2016. The official announcement can be found on the NatHERS website.

This change means that after 9pm on 30 April 2016 FirstRate5 files created using v5.1.11c will no longer calculate automatically on the FirstRate5 website.

Any projects currently underway in FirstRate5 v5.1.11c need to either be completed with a final certificate issued by 9pm on 30 April 2016, or updated in the current version of FirstRate5 for completion after 1 May 2016.

As of 20 April 2016, the most current FirstRate5 version is v5.2.2c (3.13). Thermal performance assessors should regularly check the FirstRate5 website to ensure they have the most current version of the software as updates are released on a regular basis.

The changes above do not effect FirstRate5 v5.2.x (3.13), which continues to remain accredited by the NatHERS National Administrator.

In summary, from 30 April 2016:

  • FirstRate5 v5.1.11c will no longer be accredited by NatHERS and will not calculate automatically on the FirstRate5 website.
  • FirstRate5 v5.2.2c (3.13), or the most current subsequent version of FirstRate5, will be accredited by NatHERS and calculate automatically on the FirstRate5 website.

Note: It is the user’s responsibility to ensure certificates are produced with the appropriate version. If a user chooses to inappropriately use an earlier version of FR5 to produce a certificate, they run the risk that a Building Surveyor will reject the certificate leading to further certificate costs.
