Making old homes green: pioneering retrofit research released

The first tranche of results from the Technology Strategy Board Retrofit for the Future programme have been released

The Technology Strategy Board (TSB) has released data from their energy efficient retrofitting scheme.

Figures based on 37 homes across the UK show a strong link between good air tightness and lower CO2 emissions.

Of the 37 properties, three achieved CO2 emission reductions equivalent to over 80 per cent compared with 1990 average levels, and a further 23 achieved a reduction in CO2 emissions equivalent to between 50 and 80 per cent.

The project was aimed at addressing the government’s target to reduce carbon emissions by 80 per cent by 2050.

Data from the programme will be made available through a dedicated website which will enable others to analyse the data to inform their own project choices. 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.

Speaking at a roundtable discussion on the findings Paul Ruyssevelt of UCL’s Energy Institute said: ‘The data and the website will be an important resource for scaling up retrofit. Through the Retrofit for the Future programme we allowed participants to pitch their innovative ideas for retrofitting the UK’s housing stock. A single demonstration project wouldn’t have allowed that.

‘This way we got variety and learned what we could do while also learning what won’t be possible.’ 

He added: ‘The results show that many projects are already prepared for the 2050 targets, and this is a major step change for the UK retrofitting industry.’

Nicholas Doyle, of Places for People said: ‘The report will be easily accessible, even by those who are not technically minded. This will help to bring retrofit into the mainstream.’
