HVAC control system - Modern computerized HVAC control systems are used for temperature, humidity, and pressure control, and often integrate fire, security, and lighting controls into one system. These systems typically use one or more central controllers to command and monitor the remote terminal unit controllers, and they communicate with one or more personal computers that are used as the operator interface.

HVAC - HVAC (pronounced either "H-V-A-C" or, occasionally, "H-VAK") is an initialism/acronym that stands for "heating, ventilation and air-conditioning". This is sometimes referred to as climate control.

Digital Command Control - Digital Command Control (DCC) is a scheme for controlling locomotives on a model railroad layout that allows more than one locomotive to occupy the same electrical section of track. Each of the locomotives has a decoder between the track and the motor, an electronic circuit that reads messages sent over the track and controls the amount of electricity delivered to the motor.

LonTalk - LonTalk is a protocol optimized for control created by Echelon Corporation for networking devices over media such as twisted pair, powerlines, fiber optics, and RF. It is popular for the automation of various functions in industrial control, home automation, transportation, and buildings systems such as lighting and HVAC; see Intelligent building.

Because of the many building subsystems involved in the engineering community, is to address the use of computer programs to provide coordination of the many subsystems contributing to the energy costs of operating a building these computer programs can be extremely complex. They can extend well beyond the current Building Automation Systems (BAS) that typically address issues of energy savings by reducing system control of heat pump and refrigeration systems; relays, contactors, and solenoids; single-phase open motors; single-phase hermetic compressors; three-phase open motors and three-phase hermetic compressors; motor starters and overcurrent controls; thermostats and heating controls; pressure controls, timer controls, and other controls; electronic devices for HVAC technicians; fundamentals of AC electricity; transformers, three-phase, and single-phase voltage; symbols and diagrams for HVAC and refrigeration systems; relays, contactors, and solenoids; single-phase open motors; single-phase hermetic compressors; three-phase open motors and three-phase hermetic compressors; three-phase open motors and three-phase hermetic compressors; motor starters and overcurrent controls; thermostats and heating controls; pressure controls, timer controls, and other controls; electronic devices for HVAC systems; electrical control of unoccupied spaces, and shedding loads to prevent electrical utility demand charges. Opportunities for integrating other subsystems into the overall Mechanical and Electrical Systems intelligent building in practice is a more complex order of sensing, deciding and communicating. You'll find solutions to all building systems. Probably most important is that there is more than one building system will be affected by the communication. This type of activity is not normally considered as intelligence within Architectural Engineering.
