Degree day data


Thanks to Dave Morton of NIFES energy training division for this
Degree-day figures quantify how cold (or hot) the weather has been in a given region, expressing the result as a single index number for each month or week. They can be used to:
  • Expose abnormal seasonal patterns of consumption
  • Detect exceptional consumption caused by faults
  • Set and track fuel budgets
  • Normalise the performance of different buildings to a common basis for comparison purposes
  • Verify and quantify the savings achieved by energy-saving measures after allowing for weather variations
  • Extrapolate annual consumption from a limited period of monitoring
Learn the secrets of degree day analysis, cusum charts, energy dashboards and more at the Energy Institute on 11 February


"The data is fantastic, it is really improving my analysis here and helped to identify where we can save most energy."
- David Collier, The National Archives
