Other Heating and Cooling Sources

Other Heating and Cooling Sources

Lighting Fixtures (TC.LF)

Any lighting sources other than daylight that releases heat.

From the supporting literature (linked above), there is an association between classroom lighting conditions, lighting fixtures, and thermal comfort. Light sources and fixtures release heat which influences classroom temperature.

Appliances and Equipment (AE)

Equipment that releases heat.

From the supporting literature (linked above), classroom equipment and appliances generate heat. Some common classroom equipment includes; projectors, computers, amplifier, speakers, and microphones. The heat generated by a single computer or appliance is certainly insignificant. But the heat from a combination of all computers and appliances in the classroom can influence classroom temperature.

HVAC System

Type of heating, ventilation, and air conditioning in the room.

Thermostat Control (TC)

Users have the ability to control the thermostat in the room.
