Energy management and efficiency

Effective energy management can lead to reduced energy use and costs and help meet environmental and energy requirements. It also demonstrates to customers, suppliers and investors that your organization is using best practice to make informed decisions and create practical targets.

BSI’s energy standards can inform best practice on a wide range of activities from setting up energy management systems to performing energy efficiency calculations and creating benchmarks.

Key standards

ISO 50000 series of energy management standards

The ISO 50000 series was created to provide a comprehensive suite of standards offering good practice in energy management. The standards can be used together, or independently and are suitable for any size of organisation.

BS EN ISO 50001:2018 Energy management systems. Requirements with guidance for use.

BS EN ISO 50001:2018 helps organizations use energy more efficiently and integrate better energy management into business strategy.  It does this by outlining how to implement and maintain an energy management system (EnMS) that continually improves the organization’s energy performance and saves money.

BS ISO 50004:2014 Guidance for implementation, maintenance and improvement of an energy management system  - this standard can be used to either help implement ISO 50001 or to provide a scent of good practice guidelines to get started on implementing an energy management system.

BS ISO 50006:2014 Measuring energy performance using energy baselines (EnBs) and energy performance indicators (EnPIs) – general principles and guidance – This new standard can be used by organisations whether they have an energy management system and can be used at the facility, system, process or equipment level, or for the evaluation of individual energy performance improvement actions.

BSI ISO 50015:2014 Measurement and verification of energy performance in organisation – this standard aims to provide greater credibility around the end M&V result and the measurement of energy performance or energy performance improvement.
