3 Data Centre Energy Boundaries and Flows EUROPEAN AND INTERNATIONAL STANDARDS FOR DATA CENTRE RESOURCE MANAGEMENT KPIs CLC EN series EN :2017 EN :2017 EN EN EN x EN x ETSI EN series ETSI EN :2018 ETSI EN :2018 Information technology - Data centre facilities and infrastructures Power usage effectiveness (PUE) = E DC /E IT ISO/IEC Renewable energy factor (REF) = E REN /E IT ISO/IEC Energy re-use factor (ERF) = E REUSE /E IT Cooling efficiency ratio (CER) Specific requirements; ICT Sites ICT Sites - DCEM WUE CUE ISO/IEC ISO/IEC ISO/IEC x ISO/IEC x Energy management; Global KPIs; Operational infrastructures

4 ISO 50001, Data Centres and CEPI Edition 2: 2018 DEFINITIONS continual (energy performance) improvement - CEPI recurring process which results in enhancement of energy performance and the energy management system Continual improvement achieves improvements in overall energy performance, consistent with the organization's energy policy. energy performance indicator (EnPI) quantitative value or measure of energy performance, as defined by the organization NOTE EnPIs could be expressed as a simple metric, ratio or a more complex model. Examples of EnPIs can include energy consumption per time, energy consumption per unit of production, and multi-variable models. The organization can choose EnPIs that inform the energy performance of their operation and can update the EnPIs when business activities or baselines change that affect the relevance of the EnPI, as applicable. EXAMPLES of CONTINUAL IMPROVEMENT The total energy consumption decreases over time Total energy consumption increases but the measure of energy performance as defined by the organization improved Equipment has a predicted reduction in energy performance as it ages. A delay or reduction in the performance reduction curve due to proper operational and maintenance controls can demonstrate improved energy performance as defined by the organizational EnPIs. Uncommon in a data centre environment Impossible to assess work done in any generic sense

5 ISO Certification and CEPI STAGE 2 AUDIT. the certification body shall gather the necessary audit evidence to determine whether or not energy performance improvement has been demonstrated prior to making a certification decision. Confirmation of energy performance improvement is required for granting the initial certification. SURVEILLANCE AUDIT RE-CERTIFICATION AUDIT.. the certification body shall review the necessary audit evidence to determine whether or not continual energy performance improvement has been demonstrated. ANNUAL AFTER THREE YEARS. the certification body shall review the necessary audit evidence to determine whether or not continual energy performance improvement has been demonstrated prior to making a recertification decision. Confirmation of continual energy performance improvement is required for granting the recertification. The recertification audit shall also take into account any major change in facilities, equipment, systems or processes. Energy performance improvement can be affected by changes in facilities, equipment, systems or processes, business changes, or other conditions that result in a change or a need to change the energy baseline.

6 ISO/IEC and EN KPI Timing Periods EN :2017 EN :2017 EN EN EN x EN x These standards may be considered to be a contribution to the application of ISO in relation to the development of policy for the continuous improvement of energy management ETSI EN :2018 ETSI EN :2018 MEASUREMENT POINTS AND PROCEDURES T KPI The following procedures shall be followed. Each KPI shall be assessed over a defined period of time. All parameters relevant to the assessment of the KPI shall be measured over a period not exceeding a specified time. T KPI Dt The maximum time between measurements defines the time interval between which KPIs shall be re-assessed. T REPEAT T REPEAT Conformance T KPI = 12 months (to smooth annual temperature variations) Shorter interim values viable for internal assessment only E DC E x Dt

8 ISO 50003, Data Centres and CEPI Objective of ISO/IEC x, EN x and ETSI KPIs To monitor trends not to compare data centres Requirements for public reporting of KPIs Existing KPIs may not qualify as normalized Existing KPIs cannot be reported until 12 months has elapsed The EnPI may be valid for certification to ISO but not be of direct interest to the data centre owner/customer For a given set of data centre parameters and infrastructure design decisions there are a limited number of improvements that can be made CLC/TR series CLC/TR :2018 CLC/TR :2018 CLC/TR :2019 Information technology -Data centre facilities and infrastructures Recommended practices for energy management Recommended practices for environmental sustainability Maturity model Clear design and operational improvements. but continual improvement?
