Abstract
This research is aimed at evaluating the energy performance of an existing building in Mediterranean climate, and to assess the benefit coming from various retrofit solutions of the building envelope, such as green roof and facades. By means of dynamic simulations, validated with experimental results, the reduction in both internal air temperature and cooling load was estimated. In addition, the impact of the green shielding on the windows in terms of indoor visual comfort was assessed, and suitable soluitons were envisaged.
