Degree days are used to measure the difference between a building’s base temperature and the actual outdoor temperature, multiplied by the number of days. In Planon we use two types of degree days: heating degree days and cooling degree days.

Degree days data is required if you want to be able to make fair comparisons on the sustainability of buildings in different geographical locations and over longer periods of time. Since weather conditions may vary to a great extent geographically, we can weigh a building’s energy consumption against the extent of additional heating or cooling that is required. In order to do this, we must establish a base temperature for each building and then calculate how often we needed to heat or cool the building additionally.

Degrees days can be added in Planon's Sustainability solution.
