Final Report Lot 9: Public street lighting - Amper

• from the perspective of energy-related impacts; the production, distribution, recycling and
disposal of the luminaire, lamps, ballast and pole contribute only marginally;
• for the other non-energy-related impacts, the pole contributes to some extent and mainly
with regard to waste, the emission of VOC’s, POP’s, PM, and heavy metals to air and water
due to the production of steel and it’s disposal and recycling processes.
In terms of product design; the pole weight, the pole material selection, the number of
luminaires attached per pole, production waste (e.g. avoiding metal scrap) and product
recycling are determinant to reduce these impacts.
8.1.3.5 Summary on sensivity analysis
• When taking into account the uncertainties, almost none of the individual options can be
favoured comparing one to another with an exception for option 11 (electronically
dimmable ballasts) and option 1+13 (HPM replacement with HPS and CMH).
• It can be concluded that reinstalling and relocating lighting poles is not a recommended
improvement option and therefore confirms the lock-in effect.
• The uncertainties can have an impact on 'estimated EU25 energy consumption' because
they rely on the underlying assumptions of this study, however they do not influence the
'energy consumption in real life.
8.1.4 Suggested additional requirements for the appropriate putting into service
Recommendation 1:
It is recommended to complement the following existing standards:
Standard series EN 13201:
• The standard gives only minimum requirements but no maximum light levels (see
7.4.3); the majority of lighting designers apply these values as standard values but
introducing also maximum values could in some cases reduce energy consumption and
light nuisance.
• The standard offers no clear solution for dimming applications as it determines traffic
density on a daily base. It would be better to determine it on hourly base so that it is
clear when and to what level the lighting can be dimmed safely.
CIE 154 technical guide:
• As the HPS (NaHP-TC) lamps are now commonly replaced after 4 years service,
Luminaire Maintenance Factor LMF should also be given for 4 years of service.
• Discrimination on LMF for outer glazing made of synthetic material (e.g. PMM or PC)
versus glass should be taken into account.
Recommendation 2:
It is important that EU25 member states undertake action to create accurate inventories of
public street lighting.
An important general remark about energy management and energy saving is the need for real
and actual data. The fact that Ireland, the UK and Belgium have these detailed data, proves that
this ecodesign requirement is not utopian and can create a market transformation toward energy
efficient public lighting. It is therefore recommended that EU25 member states undertake
action to create these inventories.
