- Sure. It's printed in your daily paper. Essentially, the industry picks the
- temperature that is to be considered "room temp." Let temp[i] be the temperature
- of the day on day i.
-
- A month's degree days is just SUMMATION(i=first day to i=last day) roomTemp - temp[i].
- That is, the number of degrees needed to have a house heated to room temperature
- across all days. (Actually, that should be an absolute value sign: degree days
- is a measure of temperature adjustment)
