New residential dwellings are required to achieve a 7 star energy rating report or equivalent in order to comply with the National Construction Code.
The 7 star energy rating report is generated using the Nationwide House Energy Rating Scheme (NatHERS) rating tools based on CSIRO’s scientific research.
The assessment process uses a thermal modelling software, simulating the required amount of energy to heat and cool the proposed building to an optimal temperature.
The result of the assessment is a star rating.
Your home’s rating depends on how well its design suit the local climate.
This performance based rating system is based on a scale of 1 – 10, where a higher star rating means the building requires less energy to maintain optimal temperatures.
A 7 Star is the new minimum efficiency rating in Australia.
This house energy rating method is the most efficient method for determining your building’s energy efficiency compliance.
Our NatHERS accreditation allows us to provide you energy efficiency assessments for all types of Residential buildings in Australia.
