was a landmark community-scale energy efficiency initiative to retrofit buildings over the next 30 years, helping make the Cambridge area the first to reach national (UK) carbon reduction targets, reduce energy bills and improve the quality of our buildings.

Cambridge Retrofit persists!

One aspect of the Cambridge Retrofit program remains. That is an advice section on retrofits for individuals and businesses.

Through our network of businesses, estate firms, building owners, local authorities, financiers, academics, national government, contractors and tenants, we mobilised the aspirations and resources of the entire community, stimulating and facilitating suites of retrofit projects. This drives down costs, attracts finance and ensures we keep to our ambitious timetable. Our projects focused on all aspects of energy in buildings from thermal envelopes to energy supply to lighting to plug load, and can be linked to more general refurbishments aimed at improving the quality, value and comfort of buildings.

Cambridge Retrofit was one of three programmes working to reduce the carbon footprint of the city and surrounding county. Together, they covered the range of public and private sector organisations, and retrofits and low carbon energy production.

This website primarily contains the archived materials from Cambridge Retrofit as it developed between 2013 and 2016. In 2017, Professor Crawford-Brown migrated back to the US and the retrofit actions of Cambridge and Cambridgeshire diffused into diverse activities by the Cambridge City Council and Cambridgeshire County Council. The materials on this Cambridge Retrofit part of the CCR website use the present tense for verbs, despite the fact that the programme is now out of operation. This is because most of the materials are copied from the old Cambridge Retrofit website when it was in full swing. 

This website explains the process followed in creating Cambridge Retrofit, provides the data and tools needed to assess targets, identify the most effective retrofit strategies and monitor progress, and to mobilise people and organisations to work together in delivering a low carbon future for the Cambridge area.

Now for a travel break. This picture is of our home in Cambridge, on Portugal Place (ours was the first home you see on the right). The building was begun in the 17th century, and is in a historic conservation district, so making changes requires a long process of approval by City Council. But even such an old home is able to be given a significant retrofit.
