Area
of a zone refers to the total square footage footprint of the zone.
This data should be entered as square feet. A rectangular zone
Area can be calculated as the length x width of the room. However,
irregularly shaped zones (e.x. L shaped zones) need to have all the
rectangles of the zone added together.
Area is used to determine:
 Heat Gain of the Floor  This is the total space of the
floor used to heat the zone.
 Heat Loss of the Ceiling  This is the total space of the
area above the zone which will figure into the heat loss of the zone.
 Amount
of material need to heat the room  We will use the area of the zone to
estimate the amount of material the room will require; e.x. Tubing,
electric mats, insulation, fastening hardware, etc.
