Building Energy Management Systems

Abstract

Building energy management systems (BEMS) are integrated building automation and energy management systems, utilizing IT or ICT, intelligent and interoperable digital communication technologies promoting a holistic approach to controls and providing adaptive operational optimization. The system may have multiple levels from individual sensors and actuators to users’ interface, to facilitate data collection, analysis, diagnose, trend finding, and decision-making. BEMS could provide flexible access to the building automation systems from several different platforms and locations. By using service-oriented abstractions to connect building, systems, and people, BEMS dynamically control indoor climate in a cost-effective manner and ensures the comfort, safety, and wellbeing of the occupants in buildings.
