Lessons from retrofit programmes to cut residential emissions - Eight international

Across In leasehold properties it is often the whole of the UK, the areas with necessary to gain permission from the highest proportion of properties the freeholder to have significant work using oil, tank or bottled gas, solid fuel carried out to the property, including and wood, are all located in Wales making changes to the heating (Stewart and Bolton, 2023). [...] Generally, the emissions impact of heating retrofit reflects the difference between the emissions intensity of the source of heating being replaced and the emissions intensity of the replacement source, mediated by changes in energy demand. [...] phase of programme is not yet available, but a process evaluation In the initial Demonstrator (SHDF(D)) conducted by Ipsos and the Energy phase of the programme (originally Saving Trust highlights some valuable intended to run to 2021 but extended as learning for future phases of the a result of significant delays to delivery), programme and grant-funded retrofit the Fund awarded grants totalling. [...] Indeed, the main criticism of the programme design is that the 12 to 18-month timeframe failed to take sufficient account of the time required to deliver retrofit projects and was inconsistent with the programme aims of encouraging innovation and generating learning about how best to implement deep retrofit at scale. [...] implies that as these households were already adequately heated, they were Another perspective on the able to ‘cash in’ more of the potential effectiveness of retrofit is to consider the energy savings of the installed measures extent to which the retrofit measures than the modelling had predicted.
