Several factors affect living space temperatures: a) Proper installation of insulation shall include correct placement behind electrical boxes, backing studs, corner framing and wiring, and around window and door openings. b) Directional orientation - north-facing rooms are generally cooler than south-facing rooms. c) Windows - glass has little insulating value and allows more heat to escape from the room. d) Rooms over garages - have insulated floors that lose heat to the unheated garage below. e) Airflow - free airflow from the supply outlet in a room to a return inlet or undercut door is essential. Generally, a minimum 25 mm space under interior doors above the finished floor covering should be provided.

Generally, a minimum 25 mm space under interior doors above the finished floor covering should be provided. e) Personal preference - personal comfort differs between individuals. f) Use of programmable thermostats. Balancing the air delivery system may not completely compensate for the effects of these factors. In determining the temperature of a room, measurements shall be taken in the center of the room at 1,500 mm above the floor. Heat loss calculations and duct designs assist in determining the furnace size and adequacy of the heating system.

Sustained high outdoor temperatures exert large loads on cooling equipment; indoor temperatures will rise until outdoor temperatures return to design levels. Skylights and large window areas can allow sunlight and heat to transfer easily into the home. Temperatures tend to vary in a multi-storey home due to normal air movement patterns. Heat gain calculations and duct designs assist in determining the equipment size and adequacy of the cooling system. Cooling is not a requirement of the Building Code.
