5.6.4 Heating & Cooling Degree Days
Although degree-days are most commonly used in agriculture, they are also
useful in building design and construction, and in fuel use evaluation. The
construction industry uses heating degree-days to calculate the amount of heat
necessary to keep a building, be it a house or a skyscraper, comfortable for
occupation. Likewise, cooling degree-days are used to estimate the amount of
heat that must be removed (through air-conditioning) to keep a structure
comfortable. Just like growing degree-days, heating and cooling degree-days
are based on departures from a base temperature. 65° F is almost always used
as this base. It is assumed for heating load calculations that the occupants,
lighting, equipment, appliances, cooking, bathing and other activities will raise
the temperature from 65° to 68°.
One heating degree–day is the amount of heat required to keep a structure at
65°F when the outside temperature remains one degree below the 65°F
threshold for 24 hours. One heating degree–day is also the amount of heat
