What is a "Heating Degree Day" and "Cooling Degree Day"?

A "degree day" is a unit of measurement that records how hot or how cold it has been over a 24-hour period. It also reflects demand for energy to heat or cool houses and businesses. The number of degree-days applied to any particular day of the week is determined by calculating the mean temperature for the day and then comparing the mean temperature to a base value of 65 degrees Fahrenheit. (The "mean" temperature is calculated by adding together the high for the day and the low for the day, and then dividing the result by 2.) For example, if the mean temperature for the day is 5 degrees higher than 65, then there has been a 5° cooling degree day. On the other hand, if temperatures have been cooler and the mean temperature is 55 degrees, then there has been a 10° heating degree day (65 minus 55 equals 10).
