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.
