Energy Retrofitting of Facade : Curtaining with Building Integrated Photovoltaic

Abstract

The use of renewable resources helps reduce reliance on fossil fuels, improve global energy security, and address environmental challenges, including climate change. Building Integrated Photovoltaic (BIPV) is on the rise because it serves the dual purpose of power generation and coordination of the indoor environment. This study demonstrates an analysis of energy innovation by BIPV on the façade of Kathmandu Valley buildings. Research is focused on comparative analysis of placements and types of BIPV in appearance that produce maximum energy. For this purpose, various types of BIPV have been studied and the appropriate type has been used for further calculations. PV sizing is conducted to build a manual calculation case, and for comparison, computer-based energy simulations were also performed using various software. The outcomes show that placing BIPVs at maximum efficiency on the east and south façades of the case building reduces 46.5% of the total monthly consumption units. Exterior energy innovations with BIPV can significantly reduce the building's monthly bills and serve as future energy mixes.
