IEC 60364-8-1:20 19（E）为所有类型的低压电气装置的设计、安装和验证提供了额外的要求、措施和建议，包括能源的本地生产和储存，以优化电力的整体有效利用。它介绍了在能效管理方法的框架内设计电气装置的要求和建议，以便以最低的电能消耗和最可接受的能源可用性和经济平衡获得最佳的永久功能等效服务。在IEC 60364系列的范围内，这些要求和建议适用于新安装和现有安装的修改。本标准适用于建筑物或系统的电气安装，不适用于产品。相关产品标准涵盖了这些产品的能源效率及其操作要求。本标准没有专门针对楼宇自动化系统。 与上一版相比，此版本包括以下重大技术变更: A）？修订附件B； b）？4.2修订版:电气装置的能效评估； c）？8.3更新:来自负载、传感器和预测的输入； d）？引入新的定义。 本团体能效出版物主要用作第1条中提到的低压电气装置的能效标准，但也用于技术委员会根据IEC指南119和IEC指南118中规定的原则制定标准。

IEC 60364-8-1:2019(E) provides additional requirements, measures and recommendations for the design, erection and verification of all types of low-voltage electrical installation including local production and storage of energy for optimizing the overall efficient use of electricity. It introduces requirements and recommendations for the design of an electrical installation within the framework of an energy efficiency management approach in order to get the best permanent functionally equivalent service for the lowest electrical energy consumption and the most acceptable energy availability and economic balance. These requirements and recommendations apply, within the scope of the IEC 60364 series, for new installations and modification of existing installations. This standard is applicable to the electrical installation of a building or system and does not apply to products. The energy efficiency of these products and their operational requirements are covered by the relevant product standards. This standard does not specifically address building automation systems.
