A Building Management System (BMS) centralizes and simplifies controlling, monitoring, and managing building services like heating, air conditioning, ventilation and more to achieve a safe, comfortable environment and energy savings. A BMS uses field devices, controllers and a central workstation to control equipment like air handlers, chillers and pumps. It provides features like user-friendly interfaces, alarm management, reporting, data logging, scheduling and remote connectivity. BMS benefits include improved indoor environment, maintenance savings, energy savings, consolidated facility control and improved management reporting.
