The primary subsystems in integrated building automation systems are HVAC, energy management, and lighting control. Inclusion of security, life safety (fire alarm, fire control and suppression, plus emergency aspects of vertical transportation), material handling, maintenance management, data/audio/video communications, and some aspects of office automation is the trend of future (see Figure 15.1). What the rapid advances in microelectronics and computer technology have done is to make possible and practical detailed, multipoint monitoring and control in real time, the result of which is a highly cost-efficient and environmentally appropriate facility.
