Abstract:

This study examines the importance of energy efficiency in hotel operations. By analyzing various factors that affect energy consumption patterns, the study aims to explore innovative strategies for reducing energy use. Hotels are known for their high energy demands due to factors such as building design, occupancy rates, and amenities. Effective management is crucial to reduce environmental impact and operational costs. The study reviews energy-saving techniques like smart HVAC systems, energy management technologies, and the use of renewable energy sources. These strategies promote sustainability and lead to significant financial savings and reduced carbon footprints. The paper aims to provide insights into achieving more efficient and environmentally responsible hotel operations by analyzing current practices and challenges in hotel energy management.
