31 Byron Square Retrofit, Cambridge

31 Byron Square in Cambridge is a whole house retrofit, designed by PRP, which was part of the Technology Strategy Board's national Retrofit for the Future programme.

The three-bedroom, semi detached property has undergone a complete low carbon retrofit to significantly reduce its energy consumption and carbon emissions using high levels of insulation, careful detailing as well as innovative materials and technologies. The project also highlighted some key challenges which need to be addressed in future retrofit projects, such as procurement methods, resident engagement  and supply chain issues.

Following the retrofit the house achieves an Energy Performance 'A' Rating, maximising the thermal performance of the fabric and significantly reducing the reliance on fossil fuels. Environmental and social monitoring of the house is being undertaken for two years and the findings will be used to influence future residential retrofit solutions.

PRP is undetaking technical inspections of 40 of the Retrofit for the Future projects on behalf of EST.
