The growing energy demands worldwide have underscored the importance of optimizing energy consumption, particularly in buildings, which account for nearly 40% of global energy use. In India, the rapid pace of urbanization has further emphasized the need for sustainable energy practices in the building sector. Addressing this challenge involves reducing energy consumption without compromising on operational efficiency. Energy optimization strategies focus on enhancing energy performance through design improvements, efficient systems, and renewable integrations. The aim of this study is to identify and propose effective strategies for optimizing energy consumption in Indian buildings, enhancing efficiency while maintaining occupant comfort. By analysing existing practices, case studies, and sustainability rating systems, the research seeks to bridge gaps and provide actionable solutions tailored to India's unique context. This will contribute to increased adoption of sustainable energy management practices in the building sector. The objectives include - a bibliometric analysis of energy optimization literature and a comparative study of case studies showing implementations, as well as an assessment of sustainability rating systems like “Leadership in Energy and Environmental Design (LEED)”, “Green Rating and Integrated Habitat Assessment (GRIHA)”. This is done to identify gaps and areas for improvement. Engaging energy professionals through questionnaires will provide additional insights into the effectiveness of current practices and opportunities for innovation. The applications of this research extend to improving building energy performance within the constraints existing on-site. The study concludes by emphasizing the critical role of evidence-based approaches in achieving long-term energy sustainability in India.
