Roof-Integrated Green Technologies, Energy Saving and Outdoor Thermal Comfort: Insights from a Case Study in Urban Environment

Green urban infrastructures have a significant impact on climate mitigation, indoor and outdoor thermal comfort energy performance of buildings. In this paper, conditions saving for space heating cooling were investigated before after the use roof-integrated green technologies. Existing models tools applied to an area located in Turin (Italy). CitySim, ENVI-met SOLWEIG GIS-based model used evaluate mean radiant temperature spaces vegetated roofs surfaces such as predicted vote (PMV), physiological equivalent (PET) universal index (UTCI). A engineering CitySim tool independence solar According shape suitability rooftop elaborated with GIS tools, some identified potential other installing collectors photovoltaic panels. results it is possible confirm that greenery can decrease until about 10? during summer season, improving savings reduction 12% consumption.
