The comfort and energy demand of a building are influenced significantly by glazed area of the facade. The glazed areas in the building are always challenging. Large glazing allows more daylight to get into the room but at the same time cause more heat gain and heat loss through the building envelop. Shading devices are very suitable elements for installing PV panels. The aim of this study is to evaluate the potential impact of different PV shading devices on energy performance and daylight of office buildings in Nordic climate.
