Buildings have a custom-designed heating, ventilating, and air conditioning system (HVAC) to which automated controls are applied. Access control, intrusion, CCTV, fire alarm, lighting control, and other building systems are also automated as a part of the building automation system. These systems are viewed by building management on-site and off-site with standard computer technology.

Direct Digital Control DDC is commonly used for BMS.

The solution is based on standard communication protocols and has three levels:

Management level
Automation level
Field level
In addition, the solution establishes these benefits:

Saving energy through controlled HVAC application, light application…etc.
Full management of all mechanical and electrical systems through SCADA system (local / remote).
Scheduled operation and life style control for comfort and convenience.
Facility and asset management to assure equipment life spare and preventive maintenance.
Security and monitoring.
Alarm function and integration (fire , intrusion , gas release).
