Using Cardiff City Regions as a case study this work investigates the potential for cost effective energy and carbon saving measures at the city region scale, taking into account characteristics and constraints in each locality. Results indicate that compositional downscale using statistical information at the local authority level can provide useful insights about the retrofit needs and potential at this level. Assumptions regarding the residential fuel mix and future electricity supply have a considerable impact on determining the cost effectiveness of measures and the potential CO2 savings, especially for local authorities with a residential housing stock and fuel mix markedly different from the assumed average. Around a quarter of the CO2 saving target for the domestic sector (if applied uniformly at all sectors) can be achieved by the measures examined in this study but significant investment and swift action is needed to achieve this potential. The approach has sought to reconcile the need to incorporate regional characteristics in broad top-down scenario work, with the reality of data and resource scarcity which hampers the implementation of detailed bottom-up models at a large scale. Using elements from both top-down and bottom-up models may be the best approach to address the needs of users at the regional and local authority level.
