Energy efficiency plays a crucial role in reducing resource consumption and promoting sustainability. It encompasses multiple domains, including material efficiency, electrical efficiency, and water efficiency. Among them, electrical efficiency is particularly significant due to the increasing global demand for energy and the need to reduce environmental impact. To assess and improve energy performance in buildings, frameworks like GRIHA (Green Rating for Integrated Habitat Assessment) introduce indices such as the Building Energy Performance Index (BEPI), which evaluates energy consumption per unit area. BEPI serves as a benchmark for identifying inefficiencies and implementing targeted solutions. This paper focuses on energy efficiency measures applicable to existing buildings, leveraging BEPI-based analysis to propose practical solutions. By adopting such strategies, buildings can significantly reduce their energy footprint while improving operational efficiency.

摘要

Energy efficiency plays a crucial role in reducing resource consumption and promoting sustainability. It encompasses multiple domains, including material efficiency, electrical efficiency, and water efficiency. Among them, electrical efficiency is particularly significant due to the increasing global demand for energy and the need to reduce environmental impact. To assess and improve energy performance in buildings, frameworks like GRIHA (Green Rating for Integrated Habitat Assessment) introduce indices such as the Building Energy Performance Index (BEPI), which evaluates energy consumption per unit area. BEPI serves as a benchmark for identifying inefficiencies and implementing targeted solutions. This paper focuses on energy efficiency measures applicable to existing buildings, leveraging BEPI-based analysis to propose practical solutions. By adopting such strategies, buildings can significantly reduce their energy footprint while improving operational efficiency.
