FirstRate5 Program

FirstRate5 Program

The FirstRate5 software calculates the amount of artificial heating & cooling required in each of the living spaces for the residents to feel comfortable when they use them throughout the year, 24 hours a day, seven days a week.

The star rating provided shows how efficient (per room) the house is, which determines how much extra the owner will have to pay in utility bills to feel comfortable in the house all year round.

Rating tools are typically computer based due to the thousands of individual calculations necessary. They are based on a calculation engine developed by the CSIRO that enables the prediction of the performance of a building on an hour by hour basis for a whole year. Included in the engine are regional climate data and the thermal properties of all major materials

The NatHERS tools can model the complex effects of building mass, roof types and many other factors including levels of insulation, air leakage, window size and performance.
