Building Energy Management Systems (BEMS)

Energy systems are essential part of buildings and facilities, which are associated with high costs, and considered key success factor of businesses and services produced from the building or facility. Energy management will protect the underlying business by allowing accurate and automated management of energy systems and supply. Energy management systems (BEMS) are computer‐based automated systems that monitor and control all energy‐related systems from mechanical and electrical equipment in buildings. Building management systems (BMS) are commonly used to automate all services and functions within the building, which include energy management. BMS connects building components with a central computer to enable the control of different variables and parameters within the building. This chapter presents energy management system (EMS) and possible ways to achieve energy monitoring, savings, and smart homes. Case studies will be discussed to analyze energy savings and reduce electricity bills. To achieve full deployment and integration with smart grids, it is essential to implement BMS and BEMS.
