NatHERS Whole of Home

Beyond Thermal Performance

The NatHERS Whole of Home assessment represents the future of energy ratings. It moves beyond the building shell to give you a comprehensive understanding of your home's total energy consumption and generation.

Our assessors evaluate heating and cooling systems, hot water units, lighting, and solar PV, providing a rating out of 100. This helps you make smarter design choices, reduce your carbon footprint, and significantly lower your energy bills.

Frequently asked questions

What is NatHERS Whole of Home?

NatHERS Whole of Home expands on the traditional thermal assessment by including the energy use of major fixed appliances (like heating, cooling, hot water), lighting, and on-site generation like solar PV. It provides a rating out of 100, indicating the overall energy performance of the home.

Is a Whole of Home assessment mandatory?

The requirement for a Whole of Home assessment is being phased in across Australia as part of the National Construction Code (NCC) 2022. It is becoming the new standard for demonstrating energy efficiency compliance.

How does this differ from a standard NatHERS rating?

A standard NatHERS rating (out of 10 stars) only assesses the thermal shell of the building—how well it keeps heat in or out. Whole of Home provides a more complete picture by including the energy consumed by the systems within the home.

Can you help me choose efficient appliances?

Yes, as part of the assessment, we can model different appliance options and provide recommendations on the most energy-efficient choices that will improve your Whole of Home rating and reduce running costs.
