The EN-12464-1 Lighting Standard specifies lighting requirements for people in indoor workplaces. It covers all indoor working areas including but not limited to offices, industry, healthcare, retail, restaurants, hotels, museums, libraries, schools, and car parks. You could say it is easier to mention what it doesn’t cover — outdoor working areas, underground mining or emergency lighting.
The latest version of EN-12464-1 replaces the previous 2011 version. The main changes include:
— The recommendations provided in the tables account for user needs more so than in the past
— The impact of visual and nonimage forming effects of light are elaborated
— Requirements for walls, ceilings and cylindrical illuminances are moved to tables
— More advice on applying requirements when designing lighting
— The new informative Annex clarifies glare requirements
— Flicker and stroboscopic effect are updated
Arguably, the most crucial change in the Standard was changing the structure so that more information is added to the tables. Previously, many users have solely focused on the minimum requirements in the tables, missing key details in the Standard, resulting in bad design and bad lighting. Or at least not up to the criteria that the previous Standard was requesting. Although the tables now have more information, it is still important to note that the central part of the Standard are the chapters before the tables.
When considering the new EN-12464-1 Standard, it’s essential to put the needs of end-users at the heart of designing future-proof lighting. However, it is often the case that the requirements of end-users are unknown, since the end-users themselves are unknown. Despite this, modern lighting controls offers excellent tools that can help tune the light according to users’ needs.
This whitepaper looks at the latest version of EN-12464-1 through the lens of lighting control. To understand the bigger picture, every designer should read the entire Standard.
