Road lighting

Road lighting definition:

• Road lighting in new lighting installations
• Retrofitting of different luminaires to existing lighting installations
• Retrofitting of different light sources to existing luminaires
• The simple replacement of light sources, lamps or luminaires on a like-

for-like basis in existing lighting installations

• It excludes lighting for tunnels, toll stations, canals and locks, parking

lots, commercial or industrial sites, sports installations, monuments and building facades.

Road lighting criteria:

Energy efficient lighting equipment Low light pollution lighting equipment Good quality and durable lighting equipment

Energy efficient lighting equipment:

• Luminaire efficacy
• Dimming control compatibility
• Minimum dimming performance
• Annual energy consumption indicator
• Metering
• Power factor

• Government institutions are obliged,

under Article 6 of the Energy Efficiency Directive, to purchase only products that comply with energy efficiency benchmarks.

• With regards to road lighting,

Regulation 245/2009 is currently in force and will be later repealed by a new Commission Regulation.

• The equipment to be installed shall

have a luminaire efficacy higher than those stated:

Dimming control compatibility

• Dimming the light output of a road lighting installation saves energy.
• Dimming is beneficial in terms of reduced costs and environmental

impacts related to energy consumption. Another benefit of dimming is that it is possible to minimise light pollution on demand.

• Criteria require lighting installation to be compatible with dimming

controls and allow for programmed switch off (might be an issue) during periods of low night time road use.

• All light sources and

luminaires shall be installed with fully functional dimming controls that are programmable to set at least

• ne pre-set level of dimming

down to at least 50 % of maximum light output.

Minimum dimming performance

Annual energy consumption indicator

• The AECI is considered as an intuitive indicator for procurers since it

effectively expresses the final electricity consumption of a particular road lighting installation. The AECI takes into account over-lighting and dimming.

• The procurer shall provide drawings of the road layout, areas to be lit,

surface reflectivity coefficient of the road which tenderers should use etc.

• This spec will likely not feature in the 2nd NAP.

Metering

• A metering system for a road lighting network may play a strategic

role in energy consumption and CO2 emission reduction measures

• Upon consultations with CAs, it resulted that since metering is already

provided at the source of electricity no additional metering is considered necessary.

Power factor

• The power factor is generally considered as the ratio of the real

power consumed by a load to the apparent power of the circuit. The highest possible power factor is 1, indicating no loss of current or distortion.

• The GPP criteria are proposing a power factor for the luminaire to be

installed at ≥0.90. A declaration of compliance is also to be provided by the tenderer.

• Ratio of Upward Light Output

(RULO) and obtrusive light

• Annoyance
• Ecological light pollution and star

visibility

Low light pollution lighting equipment:

(RULO) and obtrusive light

• The central argument for having criteria that limit the upward light
• utput ratio is to reduce the artificial brightening of the night sky but

also to help limit obtrusive light in built-up urban areas.

• The GPP criteria propose that all luminaire models shall be rated with

a 0.0% RULO. If necessary a boom angle is to be used to maintain the 0.0% RULO.

• As proof of compliance the tenderer is to provide the photometric

file(s).

Annoyance

• In cases where lighting is deemed necessary for human activity, the
• nly potential role EU GPP criteria could perhaps play is to encourage

dimming.

• This proposal is based on a literature review of ecological impacts of

light pollution on different types of species.

• The criteria suggest that in residential areas, the CCT of light sources

shall be ≤3000K and a dimming or switch-off programme shall be implemented.

• In parks, gardens and areas

considered to be ecologically sensitive, the G-index shall be ≥1.5.

• A switch off programme shall

apply to any relevant closing hours.

Ecological light pollution and star visibility

Energy efficient lighting equipment Low light pollution lighting equipment Good quality and durable lighting equipment

• All the criteria in this section are in one way or another related to guaranteeing

a minimum useful lifetime of the lighting equipment.

• Longer life products that can be repaired or even upgraded to extend their

useful life are an important part of European efforts to shift towards a circular economy.

• A lighting installation may perform well from an energy efficiency perspective

and may deliver the desired qualities of light after installation but this is irrelevant if the installation is not able to maintain such performance for very long.

Good quality and durable lighting equipment:

• Provision of instructions
• Waste recovery
• Product lifetime, spare parts and warranty
• Reparability
• Ingress Protection rating
• Failure rate of control gear
• Labelling of LED luminaires

Provision of instructions

• As lamps will probably have to be replaced or repaired at least once

during the luminaire lifetime, it is important that the procurer has sufficient information in order to carry out replacement and repair in a correct manner.

• The tenderer will be required to provide:
• 1. disassembly instructions for luminaires
• 2. Instructions on how to replace light sources
• 3. Instructions on how to operate and maintain lighting controls

Waste recovery

• Most contracts will relate to the renovation of existing lighting
• installations. This will result in the generation or waste. The disposal
• f WEEE has historically been a problem and a loss of potential

valuable raw materials.

• The GPP criteria proposes that the tenderer shall implement

appropriate environmental measures to reduce and recover the waste produced during the installation of a new or renovated lighting system.

Product lifetime, spare parts and warranty

• Extension of the lifetime of luminaires and its components reduces

the overall environmental impacts caused by shorter lifespans, raw material extraction and manufacturing processes. It also partly justifies the higher initial investment in more efficient road lighting installations.

• Warranty for a period of 5 years from the date of installation.

Reparability

• Reparability is one of the key principles that products need to

embrace to ensure the transition to a circular economy.

• The tenderer shall make sure that it is feasible and practical to access

components.

• Components must be identifiable, accessible and removable without

damaging the component or the luminaire.

Ingress Protection rating

• For all road lighting, it is necessary that no ingress of dust is allowed

and protection against water is guaranteed.

• The GPP criteria sets an ingress protection rating of IP65 or higher,

depending on the local conditions.

• IP65 rating means “No ingress of dust; complete protection against

contact” and “Water projected by a nozzle against enclosure from any direction shall have no harmful effects”.

Failure rate of control gear

• The control gear is often a weak point for the luminaire life time.
• The criteria specify that the control gear failure rate shall be lower

than 0.2% per 1000 h and be covered by an 8 year warranty for control gear.

Labelling of LED luminaires

• The luminaire proposed to be installed shall carry as a minimum,

information relating to:

• 1. Manufacturer’s name, code, serial number, and date of

manufacture

• 2. Input power rating
• 3. Upward light ratio
• 4. CIE flux codes
• 5. Correlated colour temperature (CCT)

Traffic Signals

• Red, yellow, and green signal

lights for road traffic with 200mm and 300mm roundels, in line with standard EN 12368, are included.

• Portable signal lights are

specifically excluded.

Definition:

Life cycle cost

• The life cycle cost shall be calculated based on the specifications set by the procurer, which should include:
• the timeframe
• an inventory of the traffic signals required (e.g. red ball signals, amber ball signals, green ball signals)
• the average duty cycle of each traffic signal (e.g. red signal 55 %, amber signal 2 %, green signal 43 %)
• the electricity rate (e.g. EUR 0.12/kWh).

The tenderer shall provide the following details in order to complete the life cycle cost assessment:

• the period of time that bulbs are covered by warranty for abrupt failure;
• the rated lifetime of the lamp
• the purchase cost for lamps
• the purchase cost for any ancillaries
• the purchase cost for any poles, foundations and new electrical connections
• the installation cost

Product lifetime, spare parts and warranty

• Lamps used in traffic signals need to be replaced more frequently

than lamps used in street lighting.

• The need for a warranty going beyond the standard 2 year period is

necessary in order to back up claims and assumptions made in the life cycle cost assessment.

• This criteria proposes that repair or provision of relevant replacement

parts shall be covered by a warranty of 5 years from installation.
