Initial results for cycling and gas consumption are shown in Figure 1, in which the weekly gas consumption (therms) and cycles are shown adjusted for local heating degree days
i] are monthly heating degree days
and cooling degree days respectively for region i where regions are defined as the area served by a particular power distribution company, in this case, KESC, [T.
19) The weather variables were the actual average temperatures during 1979, the highest temperature in the summer, the lowest temperature during the winter, the number of heating degree days
during 1979, and the number of cooling degree days.
In principle we could simply find the ratio of energy usage to heating degree days
using on-site weather data, and multiply by the HDD associated with the TMY3 file (See Equation 1).
5 percent, respectively, despite an overall decline in heating degree days
primarily due to warmer temperatures in the Pacific Northwest during the month of January.
Engine heat produces enough hot water to heat the facility's hangar despite being located in a region with over 5,000 heating degree days
There were only 24 population-weighted heating degree days
last week compared with 64 at the same point last year.
2 cents per kilowatt-hour, and, of course, their heating costs are less than half (2,600 heating degree days

There were 20 percent fewer heating degree days
in the first half of 2012 than in the first half of 2011, Unitil said.
However, a recent study of the last ten years' heating degree days
showed that 80-day hybrids harvested at 35% to 40% moisture content will allow for double-cropping of corn as far north as northern Illinois.
