Energy Management Systems
International standard for energy management systems (EnMS). Helps organisations improve energy performance, efficiency, use, and consumption through a systematic management approach.
ISO 50001 provides a framework for organisations to establish systems and processes necessary to improve energy performance, covering energy efficiency, use, and consumption. The standard supports organisations in reducing energy costs, meeting regulatory requirements, and contributing to voluntary commitments related to energy and greenhouse gas emissions.
At the core of the standard is the energy review process — a systematic analysis of energy use and consumption to identify significant energy uses and opportunities for improvement. Energy performance indicators (EnPIs) and energy baselines provide the measurement framework for demonstrating energy performance improvement.
ACI-certified auditors evaluate energy management systems, assess the rigour of energy performance improvement processes, and verify that energy objectives are driven by systematic analysis rather than intuition.
