Heating degree days, or HDD, are a measure of how much (in degrees), and for how long (in days), outside air temperature was lower than a specific base temperature (or balance point). They are used for calculations relating to the energy consumption required to heat buildings.
Another way of achieving the same result is to use degree day calculations. Degree days (also known as heat units or thermal units) are a way of incorporating both temperature and time into one measurement to quantify the rate of plant or insect development.All plants and insects develop in response to temperature.he basic procedure for calculating degree days is very simple, and all you need is a maximum/minimum thermometer. Each day, record the high and low temperatures. Determine the average daily temperature by adding the daily high temperature and low temperature together and dividing by two: Ave.
