The efficiency of using building integrated photovoltaics in the retrofitting of office buildings in Egypt

Abstract

The use of Photovoltaic (PV) technology has spread recently due to its significant contribution to the generation of energy as well as reducing the carbon footprint of buildings. The different materials of the building envelope contribute differently to the energy consumption of the building concerning heat transfer. This research paper aims at studying the efficiency of integrating Building Integrated Photovoltaics (BIPV) in the building skin to reduce energy consumption rates and reduce admitted solar heat gain. This study includes an energy simulation study using an energy simulation software to hold a numerical comparative study between two different types of Building Integrated Photovoltaics (BIPV) that are integrated into the building skin to contribute to reducing the energy demand by the building to determine the most efficient type. Moreover, the research states the feasibility of using them as it is tested along with the payback period of the initial cost of installing them.
