BS EN 12464‑1 specifies lighting requirements for humans in indoor workplaces, which meet the needs for visual comfort and performance of people having normal or corrected to normal ophthalmic (visual) capacity. All usual visual tasks are considered, including Display Screen Equipment (DSE).
BS EN 12464‑1 specifies requirements for lighting solutions for most indoor workplaces and their associated areas in terms of quantity and quality of illumination. In addition, recommendations are given for good lighting practice including visual and non-visual (non-image-forming) lighting needs.
Note 1: BS EN 12464‑1 does not specify lighting requirements with respect to the safety and health of people at work and has not been prepared in the field of application of Article 169 of the Treaty on the Functioning of the European Union although the lighting requirements, as specified in this document, usually fulfil safety needs.
Note 2: BS EN 12464‑1 neither provides specific solutions nor restricts the designers' freedom from exploring new techniques nor restricts the use of innovative equipment. The illumination can be provided by daylight, electric lighting, or a combination of both.
Note 3: BS EN 12464‑1 is not applicable for the lighting of outdoor workplaces and underground mining or emergency lighting. For outdoor workplaces, see EN 12464-2 and for emergency lighting, see EN 1838 and EN 13032-3.
BS EN 12464‑1 on indoor workplace lighting is useful for:
To comply with best practices for indoor workplace lighting, you need to ensure that:
BS EN 12464‑1 provides you with lighting design criteria, lighting design considerations, and the schedule of specific lighting requirements. Specified design criteria which are listed in BS EN 12464‑1 need to be verified, and that verification procedure has also been provided.
BS EN 12464-1 contributes to UN Sustainable Development Goal 3 on ensuring healthy lives and promoting well-being for all ages, because it supports the well-being of those working indoors.
