Potential of PV Façade for Supplementary Lighting in Winter

AbstractModern office and public buildings have to meet the requirement of zero-emission buildings through high insulation and integration of renewable energy sources on the own premises. The presented paper is devoted to exploring a BIPV facade potential as a source of electricity for supplementary lighting in an office room during winter. Analysis was carried out, for a typical office room with window centrally located in the facade, using simulation tool ESP-r for energy performance and Daysim for daylight luminance distribution calculation. Results indicate that electrical energy generated by BIPV cover supplementary lighting only in the room with south oriented façade
