Abstract

Due to the energy and environmental emergencies, in the last decades, goals, standards, regulations andincentives have been defined according to governmental strategies and regulations at national or locallevel. Referring to the built environment, this implies a knowledge of the energy performance of thebuilding stock that instead is still poor.A method able to characterize the energy performance of the built environment at territorial scale wasdeveloped. It follows a simplified procedure that takes into account: data available in the Energy Certifi-cate of Buildings database, data about the age of the buildings and the energy reference surfaces availablein official statistics database. The method was applied to residential buildings in Canton Ticino, in south-ern Switzerland. The results achieved were compared to information available in the Cantonal EnergyBalance, with regards to gas fueled residential buildings. The comparison reveals the global reliability ofthe method if applied at territorial scale.This method could support energy policies at regional/urban level, in order to stimulate a rational andmassive refurbishment of the built environment.Further improvements are in progress in order to provide a territorial representation of results by aGeographic Information Systems (GIS) tool.
