Degree Days in energy management

Degree days are a simplified form of historical weather data. They are commonly used in monitoring and targeting to model the relationship between energy consumption and outside air temperature. Weather normalization of energy consumption is one of the most common such uses of degree days.

Using degree days for energy management

Four valuable uses of degree days in energy management are:

  • Constructing control charts that compare benchmarked and actual energy usage (the closer they are, the greater your energy efficiency)
  • Evaluating success of savings measures
  • Detecting faults in heating systems and their control
  • Preparing annual budgets
