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.

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.
