Modelled Under Standardised Conditions

All homes are assessed following the NatHERS framework, using the same standardised assumptions to ensure fair, consistent and transparent comparisons across Australia. Actual energy bills and comfort vary depending on how you use your home. A fair comparison, not an electricity bill prediction.

    • Construction, insulation and windows

    • Shading from eaves, structures, and neighbouring buildings
