~85% of the homes we’ll need by 2050 are already built.
The average NatHERS star rating of an existing home ranges between 1.4-2.4* out of 10
The National Construction Code standard for new homes is 7*
These aren’t just star ratings, but an indication of the comfort, and the cost of heating and cooling for a home.
Improvements to houses, comfort levels and energy bills don’t need to have big up front costs. There are cost effective, simple strategies that can bring significant improvement:
airtightness (gap sealing), with consideration of fresh air management and moisture control
insulation, ceiling first and walls and subfloor if possible
heavy curtains with pelmets over windows
removal of gas and replacement with efficient electric appliances
NatHERS Existing Homes uses a tool developed by the CSIRO to generate a Thermal Performance star rating and a Whole of Home score out of 100.
