Degree day data

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


The service was launched in 1992 by Vilnis Vesma, a specialist in energy targeting and monitoring. It provides data on subscription to a wide variety of users. Visit vesma.com for more general advice and information on energy saving
