78°F - 65°F = 13 Cooling Degree Days. Example 2: The high temperature for a particular day was 33°F and the low temperature was 25°F. The temperature mean for that day was: ( 33°F + 25°F ) / 2 = 29°F. Because the result is below 65°F: 65°F - 29°F = 36 Heating Degree Days.

C. Degree-Hours Heating and cooling degree-hours are defined as the sum of the differences between hourly average temperatures and the base temperature. The number of cooling degree-hours (CDH) in a day is defined as ∑() = = − + N i CDH b Ti Tb 1 (1) where N is the number of hours in the day, Tb is the base

Cooling degree days (CDD) are a measure of how hot the temperature was on a given day or during a period of days. A day with a mean temperature of 80°F has 15 CDD. If the next day has a mean temperature of 83°F, it has 18 CDD. The total CDD for …

2. Degree-hours method Definitions of degree-time interval, such as degree-hours [1–5], degree-days [6–12] or degree-months are given in the literature. The total number of heating degree-hours for the whole heating season can be expressed as DH5O N j51 (Ti2T¯ o)j for (T¯ o#Tb)j (1)

There are 8,760 hours in a year. The table means that of the 8,760 hours, the equipment use rate was equal to full ton capacity for the hours indicated. Full ton capacity is what we get when we ask for total cooling tons for a building. Buildings will install more tons that needed so they have backup if part of the system goes down.

Here in Portland, OR our heating degree days (HDD) are just above 4500 and our cooling degree days (CDD) are 370. (found at http://www.wrh.noaa.gov) There are 8,760 hrs in a year... is there a calculation to convert degree days into hours?? Is there a corrolation?
