6 and 7 Star Energy Ratings

Home

Our Services

Overview

The National Construction Code (NCC) requires all new homes and renovations to achieve a minimum 6 or 7 Star energy efficiency rating under the NatHERS framework. This rating measures how effectively a home maintains comfortable indoor temperatures with minimal heating and cooling.

We provide accurate, fast, and compliant NatHERS Energy Ratings to support Building Permits / Construction Certificates and ensure your design meets the performance standards required by local councils and certifiers.

Our focus is to help your project achieve compliance without unnecessary cost increases or design changes.


What We Assess

Our energy assessment evaluates the key elements of your building envelope, including:

ComponentKey Factors Considered

Glazing & WindowsFrame type, glass performance, shading & thermal properties
OrientationSun exposure and passive heating/cooling strategies
