Cloud Computing-Based Building Energy Management System with ZigBee Sensor Network

As the Smart Grid is spreading, the importance of BEMS (Building Information Management System) is also increasing. For providing various and high quality services in the existing BEMS, each entity consisting of BEMS is improved. According to coverage area of a building, the number of the entity can be huge so it causes a burden of users. In this paper, we propose the Cloud computing-based BEMS. This system lessens a burden of each entity such as compute and storage resources, and the burden is taken by a centralized server, called System Manager in this paper. Therefore, every entity´s performance is minimized, and quality of services maintains.
