Understanding EnMS Documentation

Documentation is a key component of an ISO 50001-2011 Energy Management System (EnMS).  Documentation can guide behavior and activities and demonstrate what has been done within the EnMS.  Documentation helps you:

  • implement the EnMS
  • ensure its proper functioning over time
  • maintain evidence of the results that are achieved

The purpose of this guidance is to help you understand the basics of EnMS documentation.  It provides information on items that must be documented or recorded, as well as guidance for determining what additional documentation your specific organization needs to:

  • ensure effective implementation and maintenance of the EnMS
  • provide evidence of continual improvement in both the EnMS and energy performance
