This standard specifies requirements for an energy management system to enable an organization to take care of present and future energy comsumption and be able to maintain this method. It applies to those energy aspects which the organization can control and over which it can be expected to have an influence. It states requirements for ongoing improvements in the form of more efficient use of energy and energy savings. It does not itself state specific energy performance criteria. This standard is applicable to any organization that wishes to a) implement, maintain and improve an energy management system; b) assure itself of its conformance with its stated energy policy; c) demonstrate such conformance to others; d) seek certification/registration of its energy management system by an external organization; e) make a self-determination and self-declaration of conformance with this standard. All the requirements in this standard are intended to be incorporated into any management system.
