This rapid review identified five common themes for policy makers to consider to support low carbon residential retrofits/renovations:

1. Tailor policy to decision-makers dispositions and perspectives.
2. Funding or subsidies should target up-front costs.
3. No one-size fits all, so tailor for contextual factors.
4. Implement earlier rather than later and also earlier in the building life-cycle.
5. Take a comprehensive systems approach to policy design and implementation.

In addition, the review identified the need for more empirical analysis of energy outcomes from any implemented policy.
