CIE
• 7 Divisions
1 - Vision & Colour
2 - Measurement of Light & Radiation
3 - Indoor Environment & Lighting Design
4 - Lighting for Signalling & Transport
5 - Exterior Lighting & Other Applications
6 - Photobiology & Photochemistry
8 - Image Technology
CIE - Process
• CIE has large number of TCs
• Most TCs generate reports
• Some TCs write standards
• TCs made up of Experts interested in thetopic
• Standards sent to ISO for adoption
CEN
• TC 169 Light and Lighting
• Main committee meets once per year toreview progress and set objectives
• All members of committee and workgroups delegates from national standardsbodies.
CEN Working Groups (1)
• WG1 - Basic terms and criteria
• WG2 - Lighting of work places
• WG3 - Emergency lighting inbuildings
• WG4 - Sports Lighting
• WG5 / JWG - Road Lighting
(Joint working group with CEN TC 226)
CEN Working Groups (2)
• WG6 - Tunnel Lighting
• WG7 - Photometry
• WG8 - Photobiology
• WG9 - Energy performance ofbuildings
• WG10 - Performance of OpticalMaterials for Luminaires

Illuminance Grid
p = 0.2 x 5logd
p- is the maximum grid cell size (m), d- is the longer dimension of the area (m)
Lighting in the Interior
• Mean cylindrical illuminance requirements in the activity spaces
Ec = 50 lx (in offices, teaching areas 150 lx) at 1.2m above floor
• Modelling Index
Ec/Eh > 0.33 at 1.2m above floor
• Directional lighting of visual task
Lighting from specific direction to create shadows and emphases
Maintenance Factor
MF = LLMF x LSF x LMF x RSMF
Follow CIE 97.2
Prepare maintenance schedule
State all assumptions
Energy Consideration
Follow therecommendations and estimation of energy requirements in EN 15193
Use lighting controlsapply
daylight dependency factor FD
FD range from 1.0 to 0.8and
absence dependency factor FO
FO range from 1.0 to 0.7
Variability of Light
Vary the Intensity and Colour of light
to support
health, emotion and stimulation of people in the work place
The schedule of interiors
53 task groups
288 task types
Em - maintained illuminance (lux)
UGRL - unified glare rating limit
Uo - illuminance uniformity
