Retrofit Can Deliver Deep Carbon Reduction

13th March, 2013

Findings from ‘Retrofit for the Future’ reveal that the retrofit industry in the UK can deliver deep carbon reductions with existing technologies and practices without compromising the comfort of residents. The report, based upon analysis of 100 homes across the UK, shows a strong correlation between good air-tightness and lower CO2 emissions and identifies practical considerations for more effective retrofitting in the future.

The Technology Strategy Board’s report analyses both the practical experience of the participants in the ‘’Retrofit for the Future’ programme and monitored data from the retrofitted properties. The project was designed to address the challenge laid down by the UK Government’s target to reduce greenhouse gas emissions by 80% by 2050. By analysing data from over a third of the properties the report identifies the CO2 emission reductions achieved by each project initiative. Using this data, it further outlines the common challenges for the projects and solutions to overcoming these in the future. It summarises the success factors that seem to drive effective retrofit projects as time spent in project planning, strong site management, understanding the supply chain and working closely with residents.
In-depth data from the report has been made freely available online at to enable designers and developers to use real performance data when selecting the ways in which they intend to reduce carbon/energy levels in building projects. The outputs on the website will be updated as more data becomes available as one of the criteria for inclusion is that each project has a full year’s monitoring data.

“Retrofit for the Future has resulted in significant innovation, which is why we have developed this report and made the full data available to the public. It demonstrates that the comfort of occupants can be improved at the same time as energy bills are reduced. Business-led innovation has the potential to transform the low-carbon retrofit market in the UK, readying the sector for roll-out of the Energy Company Obligation (ECO) and opening up the market around the Green Deal,” said Ian Meikle, the Technology Strategy Board’s Head of Low Impact Buildings.
