本文件针对数据中心的一次能源提出了能源生产、储存、再利用和消费的表达要素，同时考虑到能源评估所需的要素和ISO52000系列用于建筑能源性能（EPB）。 本文件: —？提供ISO的主要定义和概念为数据中心进行一次能源评估需要52000个系列； —？提供了识别给定数据中心使用的真实能源的方法； —？在相关情况下，比较ISO/IEC中使用的术语30134系列和ISO52000系列，并提供了将最终或输送的能量转换为初级能量的因素的使用说明，这些因素在每个系列中采用不同的方法（以及如何从一个转换到另一个）； —？说明了使用EPB方法对数据的影响- 中心能源相关关键绩效指标（KPI），包括一般指标和举例说明； —？提供了当没有公认或商定的适用于所研究的数据中心能源性能评估的本地因素时使用的已知加权或转换因素来源。

This document proposes elements for the expression of energy production, storage, reuse and consumption in reference to primary energy in data centres, taking into account both the elements needed for energy assessment and the concepts developed in the framework of the ISO？52000 series for energy performance of buildings (EPB). This document: —？provides the main definitions and concepts from the ISO？52000 series needed to make a primary energy assessment for data centres; —？provides approaches for discriminating true sources of energy used by a given data centre; —？compares, where relevant, the terms used in both the ISO/IEC？30134 series and ISO？52000 series and provides explanations on the use of factors for converting final or delivered energy to primary energy which take a different approach in each series (and how to move from one to the other); —？illustrates the impact of using the EPB approach on data-centre-energy-related key performance indicators (KPIs), both in general and by the provision of examples; —？provides known sources of weighting or conversion factors to be used when there are no recognized or agreed local factors applicable to the studied data centre energy performance assessment.
