Technical Terms

Is the use of pressurized air to persunzed air to perform certain mechanical action

• Relay, contactors, motor starters

• Pneumatics

• Master thermostat

• Energy use intensity

In ductwork between the supply and the return at the air handler

• Normally closed damper

• Actuators

• variable frequency drive

• Bypass damper

Variable frequency drive may be used to drive compressor and blower motor

• Master thermostat

• variable frequency drive

• Building automation system (BAS)

• Pneumatics

a damper that opens and closes in reaction to static pressure

Sets the mode of the system (determines whether the system runs in heating or cooling model)

• Pneumatics

• Master thermostat

• Relay, contactors, motor starters

• BACnet (building automation control network)

In the open position when power is not applied to its motor

In the closed position when power is not applied to it motor

These dampers require power to open and power to close

• Master thermostat

• Master thermostat

• Power open/ closed dampers

• Master thermostat

is a conservation concept in which a building is viewed in terms of its total energy usage

Which acts as a master system that controls all of the individual energy management systems, or sub-systems

• Bypass damper

• (MUI)

• Building automation system (BAS)

• (BAC)
