The Influence of the Urban Heat Island over Building Energy Demand: the Case of Milan

Dynamic energy simulation tools of building energy consumption usually require as climatic input a Test Reference Year, which reports hourly values of dry-bulb air temperature, solar radiation, relative humidity and wind velocity. For the city of Milano (Northern Italy) unfortunately this sequence is available only from old data measurements in a non-urban context (local airports). Therefore, in this paper, a new TRY based on data collected in the centre of Milan is proposed. Consequently, energy demand simulations are carried out for a building type widespread in Milan using urban and non-urban data. The aim of this paper is hence to achieve a first evaluation of the influence of the Urban Heat Island in Milan over the energy demand of buildings
