Actual
heating degree days in the Kansas service area were 300 in the second quarter 2015, 27 percent warmer than normal and 27 percent warmer than the same period last year;
HDD =
heating degree days (base temperature appropriate to specific building)
8) A degree day is defined relative to a base temperature wherein the
heating degree day (HDD) refers to a day when temperature is lower than the base and heating is required to reach the base temperature and vice versa.
Equation (5) substitutes
heating degree days in 1979 for average temperature and finds that the colder the winter, the higher the death rate.
The
heating degree days in equations (5) and (6) account for the difference between inside and outside temperatures.
Actual
heating degree days in the Kansas service area were 2,515 in the first quarter 2015, relatively normal and 13 percent warmer than the same period last year;

Actual
heating degree days in the Oklahoma service area were 1,339 in the fourth quarter 2014, 3 percent colder than normal and 14 percent warmer than the same period last year;
The degree day-based method is based on the relationship between natural gas use and
heating degree days, resulting in a linear model that can be used to project energy use assuming no retrofit took place and a model to project post-retrofit gas use.
Climatic design conditions and cooling and
heating degree days were calculated using data from different decades for 1274 stations worldwide.
AER forecasts include monthly minimum temperatures, and energy sensitive parameters such as,
heating degree days and population-weighted
heating degree days.
21 weather primarily due to 23 percent higher cooling degree days and 14 percent higher
heating degree days than 2009.
