Abstract

In order to define an energy policy aimed at energy efficiency and to evaluate its outcome, it is necessary to know exactly and in a detailed way energy consumptions in relation to the main factors explaining energy consumption levels and their evolution over time.

This knowledge can only be ensured validly through a system of permanent statistical surveys of energy users. This paper describes the work that has been carried out by CEREN on the commercial sector in France.

This sector as well as the transport sector are the most dynamic in terms of energy demand. Understanding these dynamics contributes to a better orientation of the energy policy. This understanding begins by the direct gathering of pieces of information and by gradually building up relevant structural characteristics :

• Breakdown total commercial sector use into relatively homogenous sub-branches.

• Breakdown sub-branch energy by end use.

• Breakdown annual energy demand changes into :

  - demand growth resulting from the sector? increase in output,
  - demand changes resulting from technical improvements reflecting the effects of energy efficiency changes.

• Unit consumption and standard deviation to evaluate the results of energy saving actions.
