Energy Management System (EMS) is an intelligent and complete solution that helps optimize energy usage, improve productivity and increase energy efficiency resulting in substantial cost savings.
A Building Management System (BMS), otherwise known as a Building Automation System(BAS), is a computer-based control system installed in buildings that centralized controls and monitors the building’s mechanical and electrical equipment such as Heating, Ventilation and Air-conditioning (HVAC), Illumination (lighting) Control, Electric Power control, Control Panel, Fire Alarm System, Plumbing, and Security System, Access Control, Closed-Circuit Television (CCTV), PA System, Alarm Monitor, Lifts, Elevators, other Engineering Systems etc. A BMS consists of Software and Hardware.

Advantage of EMS & BMS/BAS:
• Can manage & monitor the building centrally or using remote management. You can also control & monitor to individual subsystems
• More effective building management, predictable energy consumption & Save money and time during maintenance
• Information is easier to access using the management system. Can detect problems earlier.
