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.
Our energy assessment evaluates the key elements of your building envelope, including:
| Component | Key Factors Considered |
|---|---|
| Building Fabric | Wall, floor, and roof insulation levels |
| Glazing & Windows | Frame type, glass performance, shading & thermal properties |
| Orientation | Sun exposure and passive heating/cooling strategies |
| Shading & Eaves | Thermal control across seasons |
| Ventilation & Air Tightness | Heat retention and natural airflow potential |
| Thermal Zones | Layout and conditioning areas to improve energy performance |
We aim to balance energy performance with practical construction methods and project budget.
