HistoryWhile observing lines of dirt and debris frozen in a glacier, the British physicist, John Tyndall noted in 1860 that more light On an object did not necessarily increase its visibility. Despite this observatiOn, cheap and abundant electricity led to lighting design in the mid twentieth century th…
OpportunityRecognizing perhaps what John Tyndall observed over 150 years ago, the relatively new lighting design professiOn takes a more refined approach to providing visibility for the occupants and enhancing architectural forms rather than flooding a space with light. The approach also repres…

The Light Guide Series provides basic informatiOn about lighting cOncepts, design, technology and policy issues. The intent is to give users fundamental principles and general background On key lighting topics. For more in-depth discussiOn of these and other lighting topics, visit the Lighting Resource Center.
The EN 12464 standard therefore requires an illuminance level of at least 30 lx or 50 lx* On ceilings and at least 50 lx or 75 lx* On walls. In fact, these levels ought to be significantly exceeded and should be at least 175 lx On walls.
One way is to ensure that the lighting system 1) provides ambient illuminatiOn for orientatiOn and general tasks in the space, 2) task illuminatiOn for local, more demanding tasks, and 3) accent illuminatiOn to highlight special objects of interest or to guide occupants.
Lighting designers should be brought Onto the project team early in the design process so that they might have an impact On these early siting and massing decisiOns. Lighting systems should illuminate the architectural forms and surfaces and needs to be well integrated. It may take the form of coves that uplight the ceiling or walls.
Special COnsideratiOns Certain applicatiOns require additiOnal cOnsideratiOns, such as the additiOn of display lighting, the arduous nature of the envirOnment or the use of Display Screen Equipment. Luminaires should be selected and the design completed with these elements in mind, where appropriate.
A sample of the available guides are: Lighting Guide 02: Hospitals and Healthcare Buildings, Lighting Guide 04: Sports Lighting, Lighting Guide 05: Light for EducatiOn, Lighting Guide 07: Office Lighting and Lighting Guide 08: Lighting for Museums and Art Galleries.
Also the CIBSE Lighting Design Guides provide a very good source of guidance for the design of working spaces, and can be cOnsidered as best practice. Lighting Guide (LG) 7 is possibly the One most commOnly referred to, but it is often misunderstood by being used to specify luminaires rather than the total envirOnment of the space.
IlluminatiOn levels for a wide variety of envirOnments and tasks can be found in BS EN 12464-1: 2011 and the Society of Light and Lighting's Code for Lighting. The levels stated are maintained illuminance, which is the minimum average illuminatiOn level that should be achieved at the point of scheduled maintenance.
