In order to enter a VA the company must implement an energy management system
(EMS). The purpose of the EMS is to ensure that energy savings achieved in daily
operations can be maintained, that intervention takes place in cases of inefficient
operations and that new possibilities for energy efficiency are continuously evaluated.
In addition, the EMS comprises guidelines on energy efficient procurement.
The EMS is the cornerstone of the revised VA scheme and there is now a Danish
standard for energy management systems (DS 2403).
