Abstract


As the majority of the dwellings that will exist in 2050 in the UK have already been built, improvements to the energy efficiency of the UK housing stock will have to be obtained primarily by retrofitting existing buildings. This study uses a bottom-up physical model to explore the potential energy and carbon savings that six retrofit options can deliver to the UK domestic sector. These retrofit options include fabric improvements and boiler replacements and aim to reduce the energy demand for space heating. It was found that 97% of all dwellings can benefit from at least one retrofit option, while the combination of all measures has the potential to reduce CO2 emissions by 38%. A breakdown of energy use by built form, age and floor area showed that detached houses should be targeted as they account for 53% of the potential CO2 emission reductions of the entire housing stock.
