C-FACTOR (THERMAL CONDUCTANCE)
The coefficient of
				heat transmission (surface to surface) through a building component or
				assembly, equal to the time rate of heat flow per unit area and the unit
				temperature difference between the warm side and cold side surfaces (Btu/h
				ft2
								×
								°F) [W/
				(m2
								× K)].
CAVITY INSULATION.
Insulating material located
				between framing members.
CIRCULATING HOT WATER SYSTEM.
A specifically
				designed water distribution system where one or more pumps are operated in the
				service hot water piping to circulate heated water from the water-heating
				equipment to the fixture supply and back to the water-heating equipment.
CLIMATE ZONE.
A geographical region based on

.
CONDITIONED SPACE.
An area, room or space that is
				enclosed within the building thermal envelope and that is directly or
				indirectly heated or cooled. Spaces are indirectly heated or cooled where they
				communicate through openings with conditioned spaces, where they are separated
				from conditioned spaces by uninsulated walls, floors or ceilings, or where they
				contain uninsulated ducts, piping or other sources of heating or
				cooling.
CONNECTED THERMOSTAT.
An internet enabled device
				that automatically adjusts heating and cooling temperature settings.
CONTINUOUS AIR BARRIER.
A combination of materials
				and assemblies that restrict or prevent the passage of air through the building
				thermal envelope.
CONTINUOUS INSULATION (c.i.).
Insulating material
				that is continuous across all structural members without thermal bridges other
				than fasteners and service openings. It is installed on the interior or
				exterior or is integral to any opaque surface of the building envelope.
CURTAIN WALL.
Fenestration products used to create
				an external nonload-bearing wall that is designed to separate the exterior and
				interior environments.
