Pathways to scale: Retrofitting one million+ homes

7 Conclusions The fast-track project has provided opportunity to explore and learn from previous and existing programs as well as consider the current landscape, the portfolio of action and the delivery model required for a large-scale home retrofit scheme in Australia. This has shown us that the task ahead is large and highly complex, yet feasible through collaborative efforts. And now more than ever before.

The fast-track project has allowed the development of scheme design principles which will guide further scheme development, testing and piloting. The home retrofit scheme must have clear and demonstrable goals as is shown in Table 34.

Table 34 Scheme design principles The home retrofit scheme aims to create: Future ready homes, meaning homes that are comfortable as well as highly thermal and energy efficient, with a path toward electrification Improved NatHERS rating for each home Market transformation Culture shift toward demanding comfortable and energy efficient homes Large-scale delivery of home retrofits across all states and regions in Australia The home retrofit scheme will target: National Construction Code (NCC) Class 1a single dwellings that are owner occupied or tenanted, mortgaged, or owned outright Poor quality homes The home retrofit scheme must build and maintain trust with homeowners: Scheme must benefit the homeowner through a streamlined process, including finance and retrofit options Scheme must provide an offering that the homeowner wants and/or needs Retrofit options provide best case outcomes with comfort and ROI benefits understood for each homeowner The home retrofit scheme must engage at trigger points: Point of sale/purchase of home Point of advertisement for lease Point of renovation The home retrofit scheme and its partners and advocates must provide clear messaging and influence for government, industry, and homeowners: Use a values-based approach to understand customer motivations and an effective way to overcome intervention barriers Optimised Australian home comfort benefits must be further researched and communicated to the target market and government Whole of home assessments and a quality control process is critical:
