Portfolio energy analysis and condition assessment: Case study of public schools of the Lugano municipality

Abstract

Buildings significantly contribute to the overall energy balance, so an accurate approach for condition assessment, energy performance benchmarking and retrofit scenario selection is necessary. The aim of this research is to analyse the energy performance and the overall condition of public buildings in the Ticino Canton; this paper focuses on 31 school buildings of the Lugano Municipality. The analysis has been conducted using a combination of tools (PETRA, BIM, GIS) and aims at defining retrofit scenarios and providing public managers with a precise picture of their portfolio. This portfolio investigation allows for an appropriate building operation and management strategy.
