英文名称：General methods for predicting energy savings

发布日期：2019-02

标准范围

本文件规定了使用基于测量的计算方法（也称为自下而上或基于能源性能改进措施（EPIAs））计算预测节能（PRE）的一般方法（见ISO 17742）。基于指标的方法（见ISO 17742）和基于总消耗量的方法（见ISO 50047）不包括在本文件的范围内。本文件提供了分类和选择方法的一般原则，并考虑了上下文、目标准确度和可用于计算压力的资源。它还为确保PrES质量的条件、文件和验证提供指导。适用于任何以下情况的压力计算:-EPIA类型；-终端使用部门；-能源最终用途；-能源节约的聚合水平；-利益相关者。注1:利益相关者可以包括私人或公共组织、能源审计员、能源服务公司、能源和设备供应商、政策制定者等。本文件考虑了以下方面的压力:-EPIA；和/或-行动计划、计划或政策（累计节能）。注2:行动计划、方案或政策可在不同规模（组织、城市、地区、国家）实施。本文档描述了如何计算预测期内的压力。它可用于根据一次能源或最终（或交付）能源（定义见ISO 50047和ISO/IEC 13273-1）计算压力。

This document specifies general methods for the calculation of predicted energy savings (PrES), using measure-based calculation methods, also known as bottom-up or energy performance improvement actions (EPIAs)-based methods (see ISO 17742). Indicator-based methods (see ISO 17742) and total-consumption-based methods (see ISO 50047) are not included in the scope of this document.This document provides general principles for categorizing and choosing the method, taking account of the context, targeted accuracy and resources available for calculating the PrES. It also provides guidance on the conditions for ensuring the quality of the PrES, their documentation and validation.It is applicable to calculation of PrES for any:— type of EPIA;— end-use sector;— energy end-use;— level of aggregation of energy savings;— stakeholder.NOTE 1 Stakeholders can include private or public organizations, energy auditors, energy services companies, energy and equipment suppliers, policy makers, etc.This document considers PrES from:— an EPIA; and/or— an action plan, programme or policy (aggregated energy savings).NOTE 2 An action plan, programme or policy can be implemented at different scales (organization, city, region, country).This document describes how to calculate PrES over a prediction period. It can be used to calculate PrES in terms of primary energy or final (or delivered) energy (as defined in ISO 50047 and ISO/IEC 13273-1).
