标准范围

本文件为国家、地区和城市分析能源效率和能源消耗变化以及衡量能源效率进步的方法提供了指南。它由三种不同的计算方法组成:-能量强度变化中的结构效应评估；-能源效率指数的计算；-能耗变化分解分析。本文件适用于提供一个国家、地区或城市的汇总统计评估。它不适用于计算单个消费者（例如家庭、组织、公司）的能源消耗或能源效率的变化。

This document gives guidelines for methods for analysing changes in energy efficiency and energy consumption, and for measuring energy efficiency progress, for countries, regions and cities. It is composed of three different calculation methods:— evaluation of structure effects in the variation of energy intensity;— calculation of energy efficiency indices;— decomposition analysis of energy consumption variation.This document is applicable to providing an aggregated statistical evaluation for a country, region or city. It does not apply to calculating changes in the energy consumption or in energy efficiency at the individual consumer's level (e.g. households, organizations, companies).
