Sampling method
The sampling frame is the Sirus directory (system of identification to directory of
statistical units).
The sampling method is a stratified plan by the nomenclature of activities (NTE) dedicated
to energy consumption, workforce bands, and region.
Allocations are optimised on the NTE x workforce bands, and on net energy consumption,
taking into account the average dispersion per stratum over the last 3 years. The
allowances are exhaustive above the threshold of 250 employees, big consumers of energy
and for strata of less than 10 units.
Sample size
The sample includes approximately 8,500 establishments.
