This part 8-1 of IEC 60364 provides additional requirements, measures and recommendations
for the design, erection, operation 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, recommendations and methods for the design and the energy
efficiency (EE) assessment 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, recommendations and methods apply, within the scope of the IEC 60364
series, for new installations and modification of existing installations.
This document 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.
Where another standard provides specific requirements for a particular system or installation
application (e.g. manufacturing system covered by ISO 20140 series), those requirements
supersede this document.
This document does not specifically address building automation systems.
This basic energy efficiency publication is primarily intended to be used as an EE standard for
the LV electrical installations mentioned in this scope, but is also intended for use by
technical committees in the preparation of standards in accordance with the principles laid
down in IEC Guide 119 and IEC Guide 118.
