This document optimizes the use of electrical energy by considering proper design and installation. Reach minimum while maintaining safe operation of electrical installations Energy consumption, and achieving optimal power utilization is a common requirement for the design process. In addition to the many parameters taken into account in the design of electrical installations, What is more important is to reduce the internal losses during the operation of the power distribution system. Electrical installations are designed taking into account the user, power supply and utility requirements. In addition to new installations, this document also applies to the renovation of existing electrical installations to significantly improve their energy efficiency. The optimized utilization of electric energy is energy efficiency management based on electricity price, electricity consumption and real-time adjustment. Full course in electrical installations During the life cycle, efficiency is tested through measurement. Improvements and improvements in energy efficiency can be achieved by redesigning or replacing equipment. the purpose is Design and install an efficient electrical installation based on acceptable investment, and perform power management processes to meet user needs. this document Various energy efficiency measures have been introduced to ensure that the energy consumption of the electrical device itself is reduced on the basis of improving energy efficiency. This document is a priority It provides guidance on measures to consider return on investment, namely saving electricity, reducing electricity costs and recovering investment on schedule. This document introduces the requirements for the design and energy efficiency assessment of electrical installations within the framework of the ISO 50001 energy efficiency management approach. Requirements, suggestions and methods to obtain the most durable equivalent functions and the most acceptable balance between power utilization and economy with the lowest power consumption. Low voltage electrical installation Part 8-1.Functional aspects of energy efficiency1 ScopeThis document provides additional requirements, measures and recommendations for the design, installation, operation and inspection of various types of low-voltage electrical installations, including the use of locally developed electricity and energy storage to optimize the overall efficient use of electrical energy. This document introduces the assessment of energy efficiency (EE) during the design, installation and operation of electrical installations within the framework of an energy efficiency management system. Requirements, recommendations, and methods to obtain the most durable equivalent functionality and the most acceptable balance of power utilization and economy with the lowest power consumption.
