Volatile Organic Compounds (VOC)

generated when chemicals vaporize and form gas. Toxic to humans & environment.

Environmental Protection Agency (EPA)

Regulates VOCs

Furnace (heating)

heated air that is distributed throughout the house via a blower motor & the home’s duct system

Radiator (heating)

series of coils or pipes through which hot water or steam passes.

Boiler (heating)

heats water & convert it to steam to offer radiant heating. The steam produced is distributed throughout the home via circuit of pipes connected to radiators.

Packaged Terminal Air Conditioning Unit (PTAC) (heating & cooling)

aka fan coil unit

Heat pump (heating & cooling)

takes thermal energy from outside source & pushes it into enclosed space. uses refrigerant which is pumped by a compressor btwn two heat exchanger coils in a constant process of condensation & evaporation.

human comfort range

factors that affect this are air temp, humidity, mean radiant temp, air motion

draft sensitivity

the neck, upper back, ankles are most sensitive to drafts
