dc.description.abstract This paper presents the results of a study aimed at developing an Italian database of Typical Meteorological Year (TMY) for the global and diffuse outdoor illuminance, starting from solar irradiation measurements and luminous efficacy models. The main objective is to provide reliable climatic data to be used for the estimation of the daylight availability in buildings and predict the energy requirements for electric lighting with higher accuracy than the actual relevant standard. ENEA developed the national solar radiation atlas during the past years, implementing validated models to predict the global, direct and diffuse irradiation, starting from satellite remote sensing. For this study, the most relevant luminous efficacy models were applied to develop illuminance TMY starting from solar irradiation data. Illuminance availability curves were developed for three reference localities of the Italian territory (Milan, Rome, Palermo), highlighting how results can be used to derive the potential contribution of daylight for buildings energy applications. In order to verify the results obtained, a ground measurements compaign of the outdoor illuminance, was started to test the effectiveness of model. The first data processed, show low differences between estimated values and measured data, confirming the validity of selected model. © 2017. The Authors. it_IT
