BAS core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and device failures and provides email and/or text notifications to building engineering staff. The BAS functionality reduces building energy and maintenance costs when compared to a non-controlled building. A building controlled by a Building Automation System is often referred to as an intelligent building system. The term most commonly used in the HVAC industry is DDC or Direct Digital Control.
A Direct Digital Control System is often used to control HVAC (heating, ventilating, and air conditioning) devices such as valves via microprocessors using software to perform the control logic. Such building automation systems receive analog and digital inputs from the sensors and devices installed in the HVAC system and, according to the control logic, provide analog or digital outputs to control the HVAC system devices. These systems may be mated with a software package that graphically allows operators to monitor, control, alarm and diagnose building equipment remotely.
