Cooling Degree Day (CDD) Definition

    https://www.investopedia.com/terms/c/colddegreeday.asp
    Cooling degree days (CDD) is a measure that helps to simplify the cost of projected energy consumption. It is based on the number of days where the temperature is above 65 degrees Fahrenheit, and ...

What Are Heating and Cooling Degree Days

    https://www.weather.gov/key/climate_heat_cool
    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.

    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 …

Heating & Cooling Degree Days – Free Worldwide Data ...

    https://www.degreedays.net/
    "Cooling degree days", or "CDD", are a measure of how much (in degrees), and for how long (in days), outside air temperature was higher than a specific base temperature. They are used for calculations relating to the energy consumption required to cool buildings. Degree days also have applications relating to plant growth ("growing degree days"). However, our focus is on making …

    For example, if the average temperature on a particular day is 78°F, then that day counts as 13 cooling degree days, as a building’s interior would need to be cooled by 13°F to reach 65°F. Conversely, if the average outdoor temperature is 34°F, then that day counts as 31 heating degree days, as a building’s interior would need to be warmed by 31°F to reach 65°F.

An Investigation of Cooling and Heating Degree-Hours in ...

    http://jocet.org/papers/021-I025.pdf
    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
