Abstract

European Directive 2012/27 states that Public Administration (PA) of member states must retrofit at least 3% of the useful area per year until 2020 for reducing their energy consumptions. On the other hand, the need for retrofitting PA owned buildings crashes with budget constraints and the necessity to guarantee services at all the time. For these reasons, when considering large publicly owned building stocks it is fundamental to establish prioritizing methodologies that help decision makers to address investments properly and efficiently. The present work considers the City of Turin as a case study for establishing a methodology to analyze the energy consumption data of a large buildings stock in terms of space heating, DHW and electricity needs. The first part of the work analyzed the stock as a whole, providing useful reference values for specific energy consumptions for different building categories (offices and schools in particular) and providing a tool for investments prioritization. In the second part, five buildings have been analyzed in detail collecting full historical data about electricity and thermal energy consumption. The union between data analysis and focused on-site inspections has allowed individuating specific inefficiencies in the energy-related facilities of the buildings. A preliminary economic analysis has been also assessed to show the strong energy and cost-saving potentials of simple low-cost actions aimed at the reduction of energy consumptions in PA owned buildings.
