Abstract

Strengthening the energy efficiency of residential buildings brings numerous benefits, not only for the reduction of GHG emissions in urban areas, but also for the fight against energy poverty, which appears to be dramatically increasing. However, still little importance is attributed to efficiency on an urban scale, rather than on individual buildings, while an effective strategy is to start from the most energy-intensive neighbourhoods. The aim of this work is to propose a methodology for evaluating the energy efficiency of residential buildings on an urban scale, in the Italian geographical context, for urban planning purposes. To this end, in the absence of open data for the estimation of the buildings energy performance, a bottom-up approach is proposed that exploits the technological advances offered by GIS and BIM software, requesting input data normally available in urban planning processes. The proposed methodology is applied to the case study of Pagani, a municipality in Campania Region, Italy, showing the applicative potential of the proposed model in highly urbanized contexts, where facing the challenge of the energy transition is of absolute urgency.
