Abstract: Green roofs have caught on in cities, mainly because contribute positively to thermal behaviour of buildings equipped with them. This paper investigates the applicability to these roofs of an integrated indicator, developed by Levinson and Akbari, to assess the contribution of cool roofs to buildings’ energy consumption. A building, assumed as the reference for the Italian medium size offices, was considered and its energy performance with and without the green roof was assessed. Different sites with different climatic conditions were considered for the simulations. First results indicate that such indicator does not seem to be completely transferable to green roofs.
Keywords: Green roof, building insulation effects, building energy consumption
