Energy Management

An effective energy management system is an essential business ingredient. Are you aware of the ISO standards for energy management systems?

ISO 50001:2011, Energy management systems — Requirements with guidance for use

ISO 50001 specifies the requirements for establishing, implementing, maintaining, and improving an energy management system, whose purpose is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy use and consumption.

The standard specifies requirements applicable to energy use and consumption, including measurement, documentation and reporting, design, and procurement practices for equipment, systems, processes, and personnel that contribute to energy performance.

ISO 50001 applies to all variables affecting energy performance that can be monitored and influenced by the organization. It does not prescribe specific performance criteria with respect to energy. The standard has been designed to be used independently, but it can be aligned or integrated with other management systems.

ISO 50001 is applicable to any organization wishing to ensure that it conforms to its stated energy policy and wishing to demonstrate this to others, such conformity being confirmed either by means of self-evaluation and self-declaration of conformity, or by certification of the energy management system by an external organization.

ISO 50002:2014, Energy audits — Requirements with guidance for use

ISO 50002 specifies the process requirements for carrying out an energy audit in relation to energy performance. It is applicable to all types of establishments and organizations, and all forms of energy and energy use.

The standard specifies the principles of carrying out energy audits, requirements for the common processes during energy audits, and deliverables for energy audits.

ISO 50002 does not address the requirements for selection and evaluation of the competence of bodies providing energy audit services, and it does not cover the auditing of an organization’s energy management system, as these are described in ISO 50003.

ISO 50003:2014, Energy management systems – Requirements for bodies providing audit and certification of energy management systems

ISO 50003 is designed to assist bodies that offer audit and certification by providing the requirements to ensure competence, consistency, and impartiality in the auditing and certification process.

In order to ensure the effectiveness of energy management system auditing, ISO 50003 addresses the auditing process, competence requirements for personnel involved in the certification process, the duration of audits, and multi-site sampling.

The standard is intended to be used by certification bodies in conjunction with ISO 17021.
