PI System and ISO 50001

Blog Post created by gopal on Oct 15, 2012

Briefly, the purpose of ISO 50001 is to enable organizations to establish the systems and processes necessary to improve energy performance, including energy efficiency and intensity. It specifies requirements for an energy management system (EnMS) to develop and implement an energy policy, establish objectives, targets, and action plans.
An energy management system addresses:

  • energy supply
  • measurement, documentation, and reporting of energy use
  • procurement and design practices for energy-using equipment, systems, and processes

ISO 50001 does not itself state specific performance criteria with respect to energy. The standard applies to all factors affecting energy use that can be monitored and influenced by the organization. It has been designed to be used independently but can be aligned or integrated with other management systems such as ISO 9000 (Quality Management) and ISO 14000 (Environmental Management).


It is based on the Plan-Do-Check-Act continual improvement framework and incorporates energy management into everyday organization practices. The basis of this approach is shown in Figure 1.

The PI System provides the software to implement the data infrastructure for the EnMS data collection, performance analysis and tracking/reporting.
