NatHERS Star Rating
NatHERS Star Rating
Energy efficiency star ratings are the core of the NatHERS program and all new dwellings are required to demonstrate how they meet the energy efficiency requirements in the National Construction Code. The dashboards in this section show how the star ratings are distributed based on a variety of geographical boundaries, including climate zones, states and territories, local government areas and even postcodes.X

Average star ratings
The average star rating differs from region to region and by class of building. See how your area does in the charts below.

NatHERS heating & cooling ratings
NatHERS modelling calculates the anticipated heating and cooling loads for a dwelling. The sum of these loads determines the star rating the dwelling achieves. The loads allowed vary by climate zone.
Average heating and cooling by climate zone
The amount of energy used to heat and cool homes depends not only on the thermal efficiency of the house, but also where the house is located. Different climate zones will obviously have different heating and cooling loads and well designed homes will take their climate into account and be responsive to it.
Filters
Average heating rating by star distribution
Cooler climates will be heating dominated and homes designs will often focus on retaining heat and reducing the need for additional heating.
Filters
Average cooling rating by star distribution
Warmer climates will be cooling dominated and house designs will often focus on capturing breezes and using passive cooling techniques to keep the homes comfortable.
