US Heating Degree-Days
Standard and industrial heating degree-days.
The "Degree-Days" can be used to estimate buildings energy consumption for heating over a year.
Heating degree-day figures relates to a "base temperature" and provides a measure of how much (in degrees), and for how long (in days), the outside temperature was below that base temperature. In the US the standard base temperature is 65 oF (18.3 oC) .
For industrial buildings with temperatures maintained below 70 oF - base temperatures of 45 oF and 55 oF are used.
