All residential dwellings such as the following buildings can use 6 Star rating in their ESD report to demonstrate compliance with the NCC energy efficiency requirements:

  • Class 1a dwelling: detached house or one of a group of attached dwellings including townhouse or villa unit and terrace house.
  • Class 2 buildings: an apartment building (multi-residential) containing two or more sole occupancy units. In the case of a multi-residential, the whole building collectively (not each unit) must achieve a 6-star average (each being a 5-star minimum).
  • Class 4 part of a building: a sole residential dwelling inside a commercial building.

Star rating scheme doesn’t cover Class 1b buildings.
