Energy management is now in the global spotlight, due to the pressing need to save energy and reduce greenhouse gas emissions worldwide.
However, energy-saving technologies are only part of the strategy for improving energy efficiency.
The ISO 50001 Energy Management System (EnMS) standard is a globally accepted framework for managing energy, and providing technical and management strategies for companies to increase energy efficiency, reduce costs, and improve environmental performance.
And for larger companies ISO 50001 provides an alternative route for ESOS compliance. ESOS (Energy Savings Opportunity Scheme) is the UK Government’s chosen response to the European Union’s Energy Efficiency Directive.
ESOS applies to around 7,300 ‘large enterprises’ in the UK, enterprises that employ 250 or more staff and have an annual turnover in excess of around £42m or an annual balance sheet of around £36m. Such companies must go through regular energy audits, the first by 5th December 2015, then once again at least every four years after.
Elements of an ISO 50001 EnMS:
• Management support
• Energy Policy
• Energy review
• Energy baseline
• Energy performance indicators
• Objectives, targets & action plans
Examples of data required:
• Historical information relating to energy use
• Identification of energy saving opportunities
• Energy use for production – processes, plant, equipment, buildings etc
• Energy use for space heating
ISO 50001 is based on the management system model of continual improvement also used in ISO 9001 and ISO 14001. This means that businesses that have established quality and environmental management systems will find that an EnMS can easily be integrated using similar templates for procedures and responsibilities.
