Where Do Standards Come From?

• International – CIE / ISO

• European - CEN

• UK - BSI

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

CEN – Current Activity

• WG1

• WG2

• WG5 / JWG

• WG7

WG1

• New Convenor – Peter Thorns

• Full review of EN 12665

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
