Low-voltage electrical installations - Part 8-1: Functional aspects - Energy efficiency
IEC · IEC TC 64
The energy-efficiency part of IEC 60364, giving requirements and recommendations for designing, erecting and verifying LV installations within an energy-management approach.
On this page
Overview
IEC 60364-8-1 covers requirements and recommendations for the design, erection and verification of low-voltage electrical installations so that electricity is used efficiently within an energy-management approach. It includes local production and storage of energy. The standard applies to the electrical installation of a building or system, not to products, and does not specifically address building automation. This scope treats energy efficiency as a design matter at installation level rather than one of product selection.
The second edition of 2019 revised Annex B, subclause 4.2 on energy efficiency assessment, and 8.3 on inputs from loads, sensors and forecasts. It was published on 6 February 2019 and runs to 72 pages. The IEC webstore lists this edition as replaced; energy efficiency now also appears in IEC 60364-1:2025. The revised parts concern how efficiency assessment and measurement inputs are handled.
The document is a paid standard and only the publisher's public catalogue abstract and product data were used here; the full text was not read. Because the edition status is replaced, it should be treated as advisory rather than a binding reference, and current provisions should be checked in the relevant clauses of IEC 60364-1:2025. For data centres, the document can be read as a framework for assessing losses and metering detail in the installation.
Key points
- Covers requirements and recommendations for design, erection and verification of LV installations for efficient use of electricity.
- Includes local production and storage of energy.
- Applies to the electrical installation of a building or system, not to products; does not specifically address building automation.
- The 2019 edition revised Annex B, 4.2 energy efficiency assessment and 8.3 inputs from loads, sensors and forecasts.
- Edition 2 was published 2019-02-06 and runs to 72 pages; its status on the IEC webstore is replaced.
- Energy efficiency now also appears in IEC 60364-1:2025.
Using it in design
- In the energy module, score the electrical design for losses (transformer, UPS, cable I2R) and metering granularity.
- Because the edition status is replaced, treat the document as advisory and point users to the energy-efficiency clauses of IEC 60364-1:2025.
- For installations with local production and storage, include these elements in the energy assessment.
