Case Studies

This collection of energy management system (EnMS) case studies presents the real-world data and experiences of early adopters who use EnMS to achieve savings. These case studies describe the implementation and resulting savings from use of an EnMS, ISO 50001, or energy optimization projects.

Get Involved: Learn about the CEM Energy Management Leadership Awards, which showcase leading organizations and share their ISO 50001 successes. Now accepting entries for 2018 awards.
