Energy bookkeping is a system used to measure, analyze and report the energy consumption of different activities on a regular basis with aim to define energy efficiency and to monitor the environment impact of energy consumption.

With energy bookkeeping there is possibility to:

• monitor energy use and other energy and environmental indicators of the building,
• monitor energy costs in the building,
• identify deviations from actual energy use as expected and identifying causes,
• gather information about the building and the embedded energy systems in one place.
  

Energy bookkeeping is an effective tool for analyzing energy use from measures already implemented and a good starting point for further planning of energy efficiency measures.
