Design and Performance Assessment of Photovoltaic Building Envelopes for a Prototype Office Building in the Mediterranean

In recent years, with the depletion of energy resources, studies on the use of renewable and clean energy sources have increased rapidly. The use of renewable energy sources is particularly prominent in the construction sector, which has a high energy consumption. This study examines the energy performance of Building-Integrated Photovoltaic (BIPV) systems applied to different façade designs in a prototype office building in the Mediterranean climate, specifically designed for renewable energy use in buildings. Four different PV façade design scenarios were determined for the prototype building, and energy performance analyses were conducted using the DesignBuilder simulation program. In this context, energy performance values such as Energy Coverage Ratio (ECR) and Self-Consumption Ratio (SCR) of the scenarios were compared. As a result of the comparison, the S2 inclined PV façade demonstrated the highest ECR (42.92%) and the lowest SCR (70.9%). The findings show that facade designs and the application of PV systems are important elements in determining the building energy performance and can meet a significant portion of the energy consumption. The study contributes to the evaluation of energy performance arising from differences in PV system applications in façade designs during the building's preliminary design process.
