Term	Term Definition	Options	Unit of Measure
Compressor Staging	The compressor staging for the unit. Select "Single Stage" for units with single stage (on/off) control. Select "Multiple, Discrete Stages" for units with multiple compressors, discrete unloading stages, or compressors with stepped speed motors that are controlled to operate at discrete stages. Select "Variable" for compressors that operate at variable speeds or with modulating unloading.	View	None
Compressor unloader	Compressor unloader is (1) device for controlling compressor capacity by rendering one or more cylinders ineffective. (2) device on or in a compressor for equalizing the high- and low-side pressures for a brief period during starting in order to decrease the starting load on the motor.	View	None
Computer		View	None
Computer lab	A computer lab is for computer use and might have printers and scanners that are often located in premises such as libraries, schools, government buildings, laboratories, community centers, companies, and research centers.	View	None
Computer monitor	An electronic device, typically with a diagonal screen size greater than 12 inches and a pixel density greater than 5,000 pixels per square inch (pixels/in2), that displays a computer's user interface and open programs, allowing the user to interact with the computer, typically using a keyboard and mouse.	View	None
Computer Type	A device which performs logical operations and processes data. For the purposes of this specification, computers include both stationary and portable units, including Desktop Computers, Integrated Desktop Computers, Notebook Computers, Small-Scale Servers, Thin Clients, and Workstations.	View	None
Conceptual design	Project goals and execution framework are established and big ideas are explored. Certification goals are set. Benchmarking and certification targets are set. Cand high-level comparative analysis can be used to establish energy performance targets, and to identify energy, greenhouse gas, and water saving strategies.	View	None

Condenser	A device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance, and will transfer to the condenser coolant.	View	None
Condenser		View	None
Condenser Fan Speed Operation	The condenser fan control option used by the unit. If the unit has several constant-speed condenser fans that stage on in conjunction with multiple compressors, this should be set to ÒStepped Speed.Ó	View	None
Condenser Type	Type of condenser used for DX cooling plant.	View	None
Condensing	Boiler or furnace is capable of condensing the water vapor in the exhaust flue gas	View	None
Condensing Operation	Capability of a boiler or furnace of condensing the water vapor in the exhaust flue gas to obtain a higher efficiency.	View	None
Condensing temperature	The saturation temperature, in degrees, corresponding to the measured refrigerant pressure at the condenser inlet.	View	None
