Cooling degree days base temperature
WebA cooling degree day (CDD) is the number of degrees by which a daily average temperature exceeds a base temperature and may therefore require additional energy for space cooling. The base temperature is typically 65 °F, although different utilities and planning entities sometimes use different base temperatures. The base temperature … WebSep 2, 2024 · A cooling degree day (CDD) is a measure of how hot it is over a period of time, relative to a base temperature. The base temperature is usually set at 65°F. So, if the average temperature for a day is 80°F, that day would have 15 CDD.

WebFeb 25, 2024 · Degree days is another way of combining time and temperature, but it has different implications for heating and cooling than does design temperature. Heating degree days (HDD) – This is the number that tells you how long a location stays below a special temperature called the base temperature. I find it easiest to start with degree … Web78°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 …
