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.

FirstRate5 accredited for Thermal Assessments

by Sustainability Victoria Energy Software Team | May 30, 2023

Sustainability Victoria (SV) would like to advise that the NatHERS Administrator has granted FirstRate5 v5.5.0 (3.22) conditional accreditation under the NatHERS 2022 Software Accreditation Protocol. Refer to the NatHERS website for further information.

Whole of Home (WoH) ratings are based off the thermal shell assessment, so completing the thermal accreditation for FR5 v5.5.0 (3.22) is the first step towards submitting the FirstRate5 WoH tool for full accreditation. SV is currently in the process of updating the FirstRate5 WoH Pilot Tool to include the latest NatHERS calculation methodologies.

While SV works towards submitting the FirstRate5 WoH tool for accreditation, we will continue to work on some final enhancements to FR5 v5.5.0 (3.22) and finalise the implementation of the new certificate. SV will advise via the usual communication channels when updated thermal and WoH software tools are ready for public release.
