Lighting illuminance guidance
There are many standards pertaining to the recommended lighting lux values and the Health & Safety Executive document HSG38 provides guidance on how lighting affects the health and safety of people at work.
Our lighting designs are fully compliant with BS EN 12464-1:2011 which is the British Standards Institution guide for design and specification of lighting of indoor work places, it can be purchased from BSI directly.
The
CIBSE (The Chartered Institution of Building Services Engineers) also publishes guides to lighting requirements in different environments including:
- CIBSE Lighting guide (LG02) Hospitals and health care buildings
- CIBSE Lighting guide (LG03) Areas for visual display terminals

- CIBSE Lighting guide (LG06) The outdoor environment
- CIBSE Lighting guide (LG07) Office Lighting
- CIBSE Lighting Guide (LG08) Museums and art galleries
CIBSE publications are intended as guidance only. They have no legal standing in themselves, however, they are often cited within
project contracts. Recommended lux values (CIBSE Code for Interior Lighting, 1994) are shown below.
