Web2 HDD and CDD measure the deviation from a temperature of 65 degrees Fahrenheit over the course of the year. For each day with an average temperature lower than 65 degrees, HDD is the difference between the average temperature and 65 degrees. The annual HDD is the sum of this difference across all days with an average temperature below 65 degrees.
