In the present research the building performance by the incorporation of a Smart Window integrated by LSC components into the building envelope is investigated in terms of daylight and energy consumption. From energy point of view, the main objective of the Smart Window was to provide ''usable'' daylight to the interior of the offices, allowing the electric lighting to be replaced by natural light and reducing the heating and cooling loads. At the same time, the proposed daylight system aimed to increase visual comfort levels, ensuring a productive and enjoyable working environment. For evaluation purposes, daylight and energy simulations were performed for different configurations and modulations of the Smart Window. The software packages of Radiance Desktop and Ecotect were used for the determination of the daylight-related performance indicators of illuminance, uniformity index and daylight factor while the energy-related ones, heating, cooling and lighting demand, as well as discomfort glare, were identified by the advanced software of Energy Plus. Two case study buildings were analyzed under two dominant daylight conditions (overcast and clear sky condition). By the application of the Smart Window firstly on an office room of the South facade of ENI Donegani Institute in Novara, Italy, and secondly on a South-west office room of the Civil Engineering main building at the campus of TU Delft, Netherlands, useful conclusions were drawn. The results of the first performance analysis of the smart window showed advantages such as better control of solar radiation, higher uniformity and light distribution but also some drawbacks. The energy performance of the building, integrated by the smart window into its envelope, is strongly dependent on the type of energy that is used to cover heating and cooling demand.
