Retrofit Revealed - domestic refurbishment data analysis report from the Technology Strategy Board (TSB) Retrofit for the Future programme
This report is an analysis of the retrofitting of homes across the UK by Retrofit for the Future.
Retrofit for the Future acted as a catalyst for retrofitting over 100 homes across the UK. Of 37 properties included in this analysis, three achieved a reduction in CO2 emissions equivalent to over 80% compared with 1990 average levels. A further 23 achieved a reduction in CO2 emissions equivalent to between 50% and 80%.
This analysis includes data for all gas and electricity consumed for heating, hot water, lighting, white goods, plug loads, etc. The lowest property has estimated gas and electricity costs of £374 per year. Three more are below £500 per year, and three more are between £500 and £600 per year.
The analysis suggests a correlation between good air-tightness and lower CO2 emissions. The data also suggests that air-tightness and emissions reductions are being achieved while improving the comfort of residents.
