The document summarizes Radian Housing Association's 'Retrofit South East' project to retrofit social housing in southeast England to make it more energy efficient and reduce carbon emissions. It discusses the UK's need to retrofit most of its existing housing by 2050 to meet climate targets. The project retrofitted 33 homes in Petersfield to an advanced standard through measures like insulation, efficient appliances and solar panels, reducing regulated CO2 emissions by up to 88%. It also trained local businesses and conducted research on the benefits of retrofitting, which include job creation, health and economic savings.

This aerial picture of part of the Cranford Road estate shows the neat and airy spacing, with pleasant greens between the rows of houses. Although in complete contrast to the old town, with its splendid examples of Georgian architecture, this essential development is probably as tasteful as a Council estate can be”.

- 14. Retrofit key learning points Understanding the home & selecting correct strategy – whole house or piece meal at trigger points. Follow energy design hierarchy – Fabric first, efficient services, micro renewables (take care with unproven innovation!) Expectation versus Outcome – Evaluate social, economic and environmental aspects of project Resident briefing versus user manual - energy efficiency behaviour change campaign & 1:1vists (x3?) Baseline position - % reduction versus kWh/m2/yr or CO2/m2/yr? Ensure good Project Management - sequencing, integrating trades and control of detailing. Community liaison officer – impact on residents, decant or insitu The hidden costs of retrofit – not only capital costs of work!
