An effort is underway to harmonize certain energy-efficiency standards. Could global standardization ultimately diminish the technical effectiveness of such standards? Which will emerge as the de facto standards? This session will explore these questions, as well in data center efficiency and sustainability guidelines.

29. 50001 – Energy Management System
• Designed to be used independently, yet can be aligned or integrated
with other management systems (e.g., ISO 9001) and environmental
(ISO 14001). Applicable to all organizations.
• Requires an organization to establish, implement, maintain, and
improve an energy management system, enabling systematic
achievement of continual improvement in energy performance, energy
efficiency, and energy conservation.
• Imposes requirements on energy supply and consumption:
− Measurement
− Documentation and reporting
− Design and procurement practices for
energy-using equipment and systems
− Processes and personnel
• Applies to all factors that can be monitored and influenced by the
organization to affect energy use.
• Does not prescribe specific performance criteria with respect to energy.
