本文档将应用平台能效（APEE）指定为关键绩效指标（KPI），用于量化数据中心IT服务应用平台的能效。此KPI在部署前评估应用程序平台的能耗。此KPI的目的是测量一组目标IT设备、操作系统和中间件的能效，以便选择能效高的IT堆栈。 本文件规定了计算APEE的公式，以及公式各组成部分的定义。 本文件规定了评估和报告应用平台能源效率的测量方法。 本文件还规定了APEE使用的基准要求和报告要求。 以下主题不在本文件范围内: 1） ？KPI旨在单独评估目标IT设备硬件的能源效率， 2） ？数据中心设施的能源效率。

This document specifies application platform energy effectiveness (APEE) as a Key Performance Indicator (KPI) which quantifies the energy effectiveness of an application platform for an IT service in data centres. This KPI evaluates the energy consumption of an application platform prior to deployment. The purpose of this KPI is to measure the energy effectiveness of a set of target IT equipment, operating systems and middleware, to enable the selection of an energy effective IT stack. This document specifies a formula for calculating APEE and definitions of components of the formula. This document specifies a measurement method for assessing and reporting the energy effectiveness of an application platform. This document also specifies requirements for benchmarks to be used for APEE and requirements for reporting. The following topics are outside of the scope of this document: 1)？KPIs intended to solely evaluate the energy effectiveness of target IT equipment hardware, 2)？energy effectiveness of data centre facilities.
