7th European Symposium for protection of the Night Sky
Bled, Slovenia
5-6 October 2007

2. Agenda What is EuP IDA and EuP-project The report Recommendations
Scenario’s
EU plans with EuP
What next?

3. EuP4Light

4. Directive 2005/32/EC
Part of the European Climate Change Programme (ECCP)
EuP = Energy using Products
What: Increasing Ecological Performance of the complete life cycle.
Purpose: Reduce greenhouse gasses, beter use of the resources

5. What is EuP Impact analysis for Water / Energy / Garbage
Product related.
Must result in eco-desing requirements
Best sollutions selected in co-operation with stakeholders.
Energy Labels for refrigerators,…

6. EuP4Light Street lighthing (final text march 2007)
Office Lighting (final text may 2007)
Domestic Lighting (ongoing)
Research team:
Paul Vantichelen, B.Jansen, T.Geerken, M.Vanden Bosch(Laborelec), V.Van Hoof, L.Vanhooydonk(Kreios),A.Vercalsteren.
IDA Europe Stakeholders:
Friedel Pas, Andreas Haenel (Germany), Dr. Jan Hollan (Czech Republica), Dr. Fabio Falchi (Italy)

7. Wath is EuP Product related No items on installations
No existing legislation that is not product related

8. The report

9. The report Handles about eco-design of: Lamps Ballasts Luminaires
Combination of all
Market analyse
Expected growth of lighting in Europe.
BAT & BNAT
“fixed lighting installation intended to provide good visibility to users of outdoor public traffic areas during the hours of darkness to support traffic safety, traffic flow and public security” (EN13201)

10. Performance requirements
Must be comform with EN
Simplified road categories of EN :
Category F “fast traffic”: fast motorized traffic use only.
Category M “mixed traffic”: motorized traffic, slow moving vehicles, and possibly cyclists and pedestrians.
Category S “slow traffic”: for mainly urban and pedestrian aimes.

11. Existing leglislation
Light pollution/nuisance related:
Most existing legislation not adapted because not product related.
Lombardy law
0 cd/klm over 90°.
Minimum luminance/illuminance = maximum
Dimmable after midnight
Need to be certified.

12. Data Data is underestimated. Data for 2005 in EU-25:
Only several countries give real data
Other data incomplete, not available or no response.
Most data estimations on road data.
Data for 2005 in EU-25:
Road length: km
Number of luminaires: 58,904 mlj
Nbr luminaires/capita: 0,12
Nbr luminaires/km road: 11,075 -> 1 lum./90m
when 1lum./30m-> km lit roads => 33,2% illuminated.

13. Crime and lighting
The absolute reduction of crime by public lighting is not proven and controversial:
Exist no good studies until now.
Light alone is no cure => need social control.
Lighting CAN improve social control.
Lighting increase safety feeling.

14. Treaths to energy savings on public places
Lack of interest by authorities:
Financial aspects
Trend of city beautification: aesthetic more important then eco-desing aspects.
Lack of interest by architects.
Lack of skilled work force:
Advanced lighting saving techniques requires aditional skills:
Telemanagement
Correct installation skills
Fine tuning optic systems
Urban architects need street light design skills.

15. Light Pollution in the report
Split in:
Astronomical light pollution.
Ecological light pollution.
Sky glow most caused by light going into the sky between horizontal and 10°
No scientific proof of ecological consequences of light pollution.
>Not to deal with it until the consequences are proven.

16. Use Phase
Most efficient luminary bad used can result in very bad energy waste.

17. BAT and BNAT IP66 Self Cleaning Glasses Improve of Utilisation Factor
Limiting ULOR
Maximizing DLOR

18. Space Height Ratio (SHR)
Higher SHR have less lighting poles, less installation cost and less energy.
Curved glass have avarage SHR: 5.
FCO with flat glass have avarage SHR: 4
-> not energy efficient solution.
Brewster angle effect
More internal reflection.
More light reflected to the sky
because more light on the road
-> more sky glow.

19. Space Height Ratio (SHR)
Where the Lombardy law is active:
Flat glass FCO luminaires with SHR 5 to 5,7
By the use of anti-reflection coating.
Study not recommend it because it is not common available
Light manufactures said they not offer it everywhere because of a pattent
Pattent is from 1978
Is expired at the moment.

20. FCO reflect more light Because more light on target area.
So dim the light for have the same lumminance.
Light going into sky between horizontal and 10° cause most sky glow.

21. Recommendations

22. Recomendations Products need an information sheet (label)
Information about eco-desing parameters
Luminaires:
Street light indication + road category
Photometric data
LMF for first 4 years
Maintenance instructions.
UF for standard road conditions.
Installation instructions for optimize UF
Installation instructions to minimize light pollution.

23. Recomendations
Generic eco-design requirements on reducing light pollution:
Require manufactures during design reducing light pollution.
When no negative effect on energy efficiency.
When more evidence on environmental significance standardization commissions have to develop harmonized standards.

24. Recommendations Luminary efficiency requirements: ULOR max DLOR min
UFF
Cat. F+M
All lamp wattages 5%
75%
6,25%
Cat. S 150W<=lamp
Cat. S 100W<=lamp<150W
10%
11,76%
Cat. S 50W<=lamp<100W
15%
70%
17,65%
Cat. S lamp<50W
20%
65%
23,53%

25. Recommendations Optional use of dimmable ballasts
Cat.F +M: implementing before 2010, >=70W before 2015
Good for avoiding over lighting (reflection)
Good for controlling light depending on traffic numbers trough the night.

26. Additional recommendations
Maximum light levels.
Peformance requirements for traffic density on hourly base.
Member states need to invest in inventory of their infrastructure.

27. EU plans with EuP

28. EU plans with EuP Questions in EP:
We are busy with light pollution by EuP4Light
Brussels European Council on 9/3 on CO2 reduction:
“invites the Commission to rapidly submit proposals to enable increased energy efficiency requirements on office and street lighting to be adopted by 2008 and on incandescent lamps and other forms of lighting in private households by 2009;”

29. What is next

30. What is next… Evaluation commission of energy
Can accept of not accept the contence of the study.
Translate the recommendations in directive proposals.

31. What next Proposals go to the commissioners
Commissioners send it to EP
When Commission and EP not agree, also opinion of the European Council
=> MEP’s need to awake in time
