WebThe formula for determining the Heating Degree Day (HHD) is: To calculate HDD: Determine the base temperature or inside temperature: Find the day's average outside temperature using this formula: Use the HDD formula to … WebBy using a general climatological approach, the base temperature is set to a constant value of 24°C in the CDD calculation. If Tm ≥ 24°C Then [CDD = ∑iTim - 21°C)] Else [CDD = 0] where T im is the mean air temperature of day i. Examples: If the daily mean air temperature is 26°C, for that day the value of the CDD index is 5 (26°C-21°C).
