Cambridgeshire Retrofit Information

This mini-site is part of the Climate Change Risk Mitigation programme, with a focus on energy efficiency retrofits to buildings in Cambridgeshire. It grew out of the decision in 2019 by the villages of Histon and Impington to declare a Climate Emergency (thanks to Ros Hathorn and Stefan Haselwimmer for pointing us towards this). These villages are leading the way on tackling the threat of climate change. This site is designed to help them on that path by providing reliable information on the effectiveness of strategies for retrofitting buildings to reduce energy bills, make homes more comfortable, and reduce emissions of carbon dioxide from the community's building stock. While designed initially for those villages, the same material will be useful throughout Cambridgeshire.

Most of these materials were developed through our experience helping to manage the Cambridge Retrofit programme. You will find it useful to first take a tour of that site to see what lessons were learned and to gain a broad view of retrofits. Then return to this page to begin your personal journey to carbon reduction in your homes and offices.

Are you ready?

Having armed yourself with the Cambridge Retrofit background, it is time to begin your personal journey to retrofitting your Cambridgeshire home or business.


At CCRM, we have no financial stake in this path. Consider us a neutral, trusted partner. We are here to help you gain the information you need to take wise decisions. It is then up to you to select how you will carry out the retrofits.

But first, consider your own carbon footprint. Download the CCRM Carbon Footprint calculator to understand both the size of your footprint and the causes (so you can begin to identify strategies of reduction).

However.... Be aware that the carbon intensity of electricity production has been declining (improving) rapidly over the past decades in much of the developed world as renewables come on line. You will need to check the intensity in your own power grid and adjust this cell of the model accordingly (it is Cell D11 under the Electricity tab). It currently shows 0.000537 tCO2/kWh. In both San Diego, California (where we live part of the year) and the UK (where we live the other part), the intensity is approaching 0.0002 tCO2/kWh.



For an even quicker introduction to the community-scale retrofit process, you could begin with the two videos below. 
The first is a movie of about 9 minutes featuring the launch of Cambridge Retrofit. The second is a narrated Powerpoint presentation of about 35 minutes explaining the community retrofit process, again using Cambridge Retrofit as the example. 

Taken together, these videos show how you can identify the most effective, and cost-effective, approach to reducing energy use and carbon emissions both in your own home or business and throughout your community. As we often said in Cambridge Retrofit, we don't care why you have come to the table. 
  • Are you here to reduce the risk of climate change? Welcome to the table. 
  • Are you here to reduce your energy bills? Welcome. 
  • Are you here to set an example others might follow? Welcome. 
  • Are you here to make your home more comfortable? Welcome (so long as that comfort is not at the expense of greater emissions).
  • Are you here because you can supply retrofits? Welcome. 
We do not judge motives, only actions.
