Abstract

Over the years, different types of smart windows have been tested and developed. In this study, an innovative prototype of a photovoltaic smart window, that integrates luminescent solar concentrators, was analysed. The device independently regulates the movement of the shading system and allows energy surplus, through the electricity generated by modules. Considering the peculiar structure (characterized by the presence of a light shelf) and the thermal characteristics of the device, the analyses focused on optical, thermal, and electrical performances, comparing them with those of a traditional window. The analysis followed an experimental approach that involved lighting and electrical monitoring studies in a real test room, to create validated models for conducting simulations in larger buildings. The results were expressed through the study of illuminance maps, electricity generation obtainable from the integrated photovoltaic technology and in terms of energy savings. Energy generation accounts for around 10 Wh/month, with up to 50% improvement from the perspective of energy use for heating and cooling. The technology proves effective in allowing efficient overall energy performances while generating enough energy to operate the smart window control systems.
