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. Heating and cooling degree-days are based on
departures from a base temperature, typically 65ºF (18ºC).

One heating degree–day is the amount of heat required to keep a structure
at 65ºF when the outside temperature remains one degree below the 65ºF threshold
for 24 hours. One heating degree–day is also the amount of heat required to keep
that structure at 65ºF when the temperature remains 24ºF below that 65º threshold for 1 hour.

Likewise, one cooling degree–day is the amount of cooling required to keep
a structure at 65ºF when the outside temperature remains one degree above the
65ºF threshold for 24 hours. One cooling degree–day is also the amount of cooling
required to keep that structure at 65ºF when the temperature remains 24ºF above
that 65º threshold for 1 hour.

THW INDEX - The THW Index uses humidity, temperature and wind to
calculate an apparent temperature that incorporates the cooling effects of wind
on our perception of temperature.
