Lighting Energy Performance of an Office Building with BIPV System

This thesis aims to investigate building integrated photovoltaic systems collaborated with case study building in Istanbul-Turkey in order to evaluate their performance of energy-efficient lighting design. Energy demand of buildings requires high electricity consumption especially office spaces that use energy for lighting. Therefore some strategies such as energyefficient building design are necessary to improve a sustainable development in the existing buildings. In this thesis these strategies and importance of energy-efficient lighting technologies in office buildings are clarified.
