There are several international standards and guidelines related to energy efficiency and sustainability in data centers. Here are some of the key standards:

1. ISO/IEC 30134 Series

This tranche of standards originates in ISO/IEC JTC 1/SC 39 Sustainability, IT & Data Centres.  It provides key performance indicators for data center facilities and infrastructures. It includes:

  • ISO/IEC 30134-1: Overview and general requirements.
  • ISO/IEC 30134-2: Power Usage Effectiveness (PUE).
  • ISO/IEC 30134-3: Renewable Energy Factor (REF).

2. ISO/IEC 22237 Series

The ISO/IEC 22237 series addresses the design, construction, and operation of data centers. It includes guidelines for energy efficiency:

  • ISO/IEC 22237-1: General concepts.
  • ISO/IEC 22237-2: Building construction.
  • ISO/IEC 22237-3: Power distribution.
  • ISO/IEC 22237-4: Environmental control.

3. The European Code of Conduct for Energy Efficiency in Data Centres

This code provides a voluntary framework for data center operators and owners to reduce energy consumption. It includes best practices and recommendations for improving energy efficiency.

4. ASHRAE Standards

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) provides guidelines for data center design and operations to enhance energy efficiency:

  • ASHRAE TC 9.9: Technical Committee for Mission Critical Facilities, Data Centers, Technology Spaces, and Electronic Equipment.
  • Thermal Guidelines for Data Processing Environments: Provides environmental conditions for data centers and IT equipment.
  • ASHRAE 90.4 Energy Standard for Data Centers

5. BREEAM (Building Research Establishment Environmental Assessment Method)

BREEAM is a global sustainability assessment method for buildings, including data centers. It evaluates energy performance and environmental impact.

6. The Green Grid Metrics

The Green Grid, an industry consortium, provides several metrics and tools to improve data center energy efficiency, including:

  • PUE (Power Usage Effectiveness): Measures the ratio of total building energy usage to IT equipment energy usage.
  • CUE (Carbon Usage Effectiveness): Measures carbon emissions per unit of IT energy consumption.
  • WUE (Water Usage Effectiveness): Measures water usage per unit of IT energy consumption.

These standards and guidelines aim to provide a framework for designing, constructing, and operating data centers in an energy-efficient and sustainable manner, helping to reduce the environmental impact of these facilities.
