The study aims to gain a deeper understanding of the functions of the building management system and how it can contribute to sustainable museums. This research focuses on identifying user needs, determining BMS characteristics, and designing, installing, and operating the BMS based on existing literature. Factors such as the lack of understanding of the BMS and its capabilities, the absence of service and maintenance, and the performance of BMS vendors hinder the adoption of the BMS. This study aims to promote the use of building management systems by investigating their contribution to sustainability. It was concluded that the BMS enables uniform and effective control, monitoring, and handling of all equipment functions, facilitating maintenance and management operations. Building management systems are increasingly used in museums to ensure compliance with standards, protect assets against disasters, and provide appropriate environmental conditions and security. This enhances resource efficiency within museums and promotes sustainability.
