The retrofit program would cost approximately $176m based on refurbishment costs of between $3800-$5000 per home. This does not include cost to provide energy audits and ongoing support in the first year.
Providing solar would cost an additional $135 million, based on systems costing $2000-$3000.
Clean State advocates for the inclusion of abatement created by this program as an accredited carbon credit. Emissions abatement under this program could be packaged up as a form of WA carbon offset credit, which could generate $124.6m over 30 years at $15/tonne.
