Introduction of the meeting and participant As introduction of the meeting a short presentation on the JRC by Miguel Gama Caldas and on GPP in

general by Enrico Degiorgis (DG Env) was given to the participant.

It was presented as well, the timeline of the project revision of GPP criteria for Street Lighting and

traffic signals and the BATIS system necessary for the participant to deliver their comments on the

criteria until 23 January 2017.

The agenda of the meeting was also presented to the participants.

The participants were informed that everything said in the meeting will be made public but that no

names should be mentioned. Therefore participants were able to speak freely and on their own

behalf. Participants were also informed that the session will be recorded for the minutes of meeting

but data will be kept private by the EC.

Summary of the preliminary report JRC presented the background information and a summary of the preliminary report.

The current goal and scope of the project and definitions of the main concepts necessary to

understand the topic were presented to all participants. The first point of discussion was the revised

version of scope and definition of the EU GPP product group Street Lighting that from now on will be

called Road Lighting according to the terminology of EN 13201.

Stakeholder feedback

A stakeholder raised a question on the lack of homogeneity of the definitions that are different for

example in Ecodesign and that this could create some misunderstanding. Having the harmonized

definitions among the different standard will help to standardize the evaluation processes and the

assessment of the products.

Further standard should be considered and referred in the document, e.g. standard for outdoor for

traffic and industrial plants and related to the LED lighting. In particular for LEDs new definition are

needed to have more clarity in this concern. Therefore a guide would be needed and stakeholders

want to contribute to develop it. From a stakeholder was suggested to consider for the definition the

General lighting - Light emitting diode (LED) products and related equipment - Terms and definitions.

Regarding LED technologies it should be difficult to distinguish between led modules or system and

LED luminaires because many times LED modules includes a complete system with ballast and ready

to plug in. That is the reason to consider LED technology as a whole.

Related to the goal and scope of these GPP criteria, it should be kept as broad as possible but

consistent with the affected criteria.

JRC summarized saying that the scope of this project will be taken as broader as possible but in the

same time we are going to update and harmonize the definition according to the standards.

Comments and suggestions form the stakeholders to the document are more than welcome.

Market analysis and technical analysis.

Presentation on the market and technical analysis has been given from JRC Seville, that includes the

results on the LCA screening study and the presentation of the environmental hotspots of the road

lighting and traffic signals.


Because only environmental impacts of those products were presented the stakeholders asked if

anything on social sustainability pillar was considered in the hotspot analysis.

JRC answered that until now the interest is only on the environmental impacts. This is also because

the social sustainability is considered by another EC department and a specific guidance to integrate

social criteria in PP is now under development.

Guidance for considering renovation beyond relamping JRC presented a step-by-step guidance proposal for considering renovation beyond relamping. The

guidance step has to be implemented by the procurer before procuring any goods, to decide if a

renovation or a relamping is necessary to the current road lighting system.


Some stakeholder supported the proposal on the guidance for relamping but still some issues were

raised from them. More detailed points are reported below:

The first concern from the stakeholder was that if the only parameter used is energy efficiency, it

promotes for cold LED against or warm LEDs that are recommended in some cases to reduce light

pollution. The proposed guidance used static values and we should use dynamic ones to improve

according to the new technologies.

Concern on the static value presented form of the guidance, in fact we should think that those

GPP criteria are going to be valid for some years ahead, that is the reason to think about a

dynamic one.

A stakeholder proposed the Italian approach. In Italy parametrized energy label A-B- C- D are

elaborated for streets based on Power density Indicator - PDI values with a baseline per road

application but then the other parameters are free to be established by the designer.

JRC underlined that some of these points are going to be part of the discussion on PDI and Annual

Energy Consumption Indicator - AECI criteria.

Further points raised from the stakeholders:

Standard methods should be used in the guidance.

attention should be paid to avoid double counting of benefits in the PDI calculation, especially

related to the luminaire power to sometimes include the control gear losses in the manufacturer

data or not. Some reference values on power losses should be provided. These values are going to

be cross checked from few stakeholders to verify their validity.

Further attention should be paid to follow the newly proposed Ecodesign Regulation, indeed it

might phase out some lamps in the existing GPP in favour of LED technology.

The stakeholders in general agrees to the approach focusing on the energy efficiency because

energy represents the 90% of environmental impact, but we should be careful that it won't

increase light level on the roads, over-lighting of roads. Over-lighting can create problem for

citizens. We should consider this issue in the revision process.

Another stakeholder raised the necessity to reduce the unwanted light, important key issue, by

reducing the energy consumption and calibrating with the needs. The current standard allows

decreasing light levels and also new technologies allow fitting the right level.

To consider the economic consequences of a relamping a LCC is suggested and from a stakeholder

a Swedish approach was proposed. This approach will be delivered already translated in English

from a stakeholder. Moreover it was asked if a more refined approach such pay back cost to

reconfigure poles could be added to the proposal and some average values should be suggested

in the guidance as well, Stakeholders are going to supply average values on installation cost

values.

The fact that the proposed guidance is based on installed power as it sole parameter was well

received by stakeholders. In fact, for LED technology wattage does not have the same importance

as it has, for example, for sodium lamp technology. Besides that, distance related measurement

would be hard to conduct. JRC underlined that the formula with power as only parameter, was

proposed to make the estimation of the current installation easier.

In the proposal it could be useful to use different correction factors for electronic (1,1) versus

magnetic (1,15).

If PDI is proposed it should be used together with AECI that includes dimming.

EU GPP criteria for road lighting design

Selection criteria JRC presented the selection criteria for the design. These selection criteria are the same to the ones

in the current GPP Criteria for street lighting (2012).


Several inputs were collected by JRC from the stakeholders during the meeting.

First proposal was to use the same selection criteria used in Italian GPP: 5 years of experience and or

an engineering and architectural degree or technical high school certificate. A suggestion to add a

year of experience in relevant project design was made as well.

Extending the years of random experience from 3 years (current GPP criteria 2012) to 5 years was

seen not to be appropriate and could disturb the market offer cutting out new players. It would make

more sense making the length of experience shorter but more relevant asking as experience in the

field to the candidates list of projects.

of 14

Another stakeholder suggested adding training as an option instead of experience to give the

opportunities to new players to participate to the call.

Attention has to be paid to the reference of the lighting design software. Different software are

available on the market but different results are obtained by using different software.

Further feedbacks and options in this topic will be collected by BATIS.

TS 1 - annual energy consumption indicator (AECI) and power density

indicator (PDI The technical specifications on PDI and AECI for core and comprehensive criteria and relative

verification procedures were presented by the JRC

An alternative simplified approach to calculate PDI and AECI was presented by JRC. The formula

presented is based on a fitting of a correlation between PDI and road widths. The correlation was

observed by a detailed analysis of seven reference road designs carried out in the second quarter of

2016 (Q2/2016).


Several stakeholders are going to give their feedback through BATIS on the proposed values and

formulas. By the way Italy used PDI since 2012 and tables with value for big roads versus small roads

and cycling path can be found. For Italian implementations a good experience in using PDI criterion

was reported by the stakeholders.

The use of tiers was also supported by the stakeholders but still they prefer to postpone more

specific comments on the values presented after the meeting and to the consultation through BATIS

to better check the correlation among the different parameters.

Only one stakeholder remarked the complexity of PDI criterion and instead promoted the use of

AECI. The alternative criterion proposal based on the luminaire maintenance factor (FLLM) it is

clearly too difficult.

Regarding testing and verification specifications third party certification base on EU standards should

be required with test in laboratory conform to ISO certification.

It was suggested to use ENEC+ label but because it is a private certification, the verifying criteria

proposed there can be proposed without clearly refer to the scheme.

In 2017 an international standard is going to be available.

TS2 - Light pollution (RULO) The technical specification on RULO for core and comprehensive criteria and relative verification

procedures was presented by the JRC.


The first remark was on a mistake in the norm reference that is in the technical report: it should be

EN 13201-5 (not 6). Then it was remarked that a 1% could be too difficult in certain applications and

that it might not be so important in urban environment with surrounding buildings. A proposal to use

of 14

threshold on lumens was made by the stakeholders. They also propose to supply some references on

spectral impact.

It was mentioned that RULO is misleading confused with URL. Verifying the use of RLU vs RULO as a

requirement and it was remarked that RULO measurement might not be practical in comparison with

RLU.

It was also underlined that with LED the value of RULO can be push until 0%. According to it, a

mentioned on several France laws deal with light pollution was made, according to it several projects

have been carried out with RULO 0%.

It was also proposed to make a distinction between urban and rural areas to consider that in

residential areas it is not meaningful where the light goes. On the other hand vertical luminance in

residential area is very important and they cannot reach RULO 1%. Few stakeholders stated that with

1% amenity lighting is not possible..

AC1 - Least Life Cycle Costing (LLCC) Presentation of the use of LCC as award criteria from JRC and it was asked if it is applicable.


The Swedish example was mentioned, where LCC is currently used in GPP. A stakeholder promised to

deliver it in English version.

JRC and DG-Env mentioned the new excel tool published for calculating LCC of different product and

it was proposed to send the link to the stakeholders to collect implementations and feedbacks on it.

A further confirmation on the possible use of LCC in GPP was done from other stakeholders and it

was clearly stated that the approach won't jeopardize fair competition.

AC2 –Metering The same award criteria for core and comprehensive on Metering were presented from JRC.


It should be checked of the application of metering for road lighting is not mandatory according to

European Directives (e.g. energy service directive 2006/32/ec).

Experiences of metering in Italy were remarked from stakeholders and they proposed to provide

data costs on it. By the way, high cost of metering were reported and necessity to implement a

communication system.

Lunch break 13:30 – 14:30

After lunch a stakeholder wanted to wrap up the discussion at lunch about price and how in the

efficiency bulk procurement is missed in the GPP. More in details a stakeholder recommends that the

JRC investigate mechanisms and implementing agents that could enable the creation of a facility to

of 14

combine orders from multiple public procurers and thus achieve ‘bulk’ procurement status (and

pricing) from the suppliers. During the current workshop, several municipalities expressed concern

over capital costs and that budgets were a constraint to purchasing street lights. A proposal was that

the Commission engages with stakeholders (manufacturers, municipalities, energy service

companies, environmental non-profit organisations (like Les Eco Maires, or ICLEI – the International

Council on Local Environmental Initiatives, etc.) to discuss and explore possible ways to develop a

bulk procurement facility that would offer discounted prices if purchase orders could be merged

and/or delayed for a limited period of time while sufficient orders are built up. The GPP Advisory

Group could collect best practices and provide expertise/ guidance how such an entity could be set

up exclusively national or perhaps regional, and would accelerate take-up of the EU GPP criteria by

lowering first-cost barriers for municipalities.

A further recommendation was that the JRC develops concept for a GPP street lighting qualification /

certification system for organisations that design, procure and install LED street lighting systems with

demonstrated high competency and that meet the EU GPP core criteria as a minimum standard. With

such a GPP street lighting certification, these entities could offer municipalities turn-key solutions

which meet the GPP core or even comprehensive criteria. This certification would also help to

achieve the goals of high-quality GPP, and the entities would directly market the EU GPP criteria to

municipalities and other public procurers, highlighting the benefits of green procurement and

accelerating its take-up. Thus, GPP criteria for lighting design are important, but some kind of official

scheme for accreditation or certification to these criteria would accelerate take-up and increase the

impact.

EU GPP criteria for road lighting equipment JRC presented the criteria grouped in two parts:

Luminaires, and

Light sources

EU GPP criteria for road lighting equipment – Luminaires

TS1 – Efficacy and lifetime of luminaires Presentation on the proposed criteria for efficiency and lifetime was made by JRC.


Different points of views can be summarized relate to this criteria.

As first a stakeholder introduced the point that the efficacy (105 lm/W) could be too ambitious in

specific applications such as public park and green applications, etc. and therefore we could specify

90 lm/W for those specific applications. Moreover related to HID lamps the requirement introduced

by the Ecodesign directive are enough, so we do not need to consider HID in GPP.

A new initiative to develop a calculation method for LED package lifetime and to make this value still

valid for module and luminaire is currently on going as work item in ICE but until now it was

complicated to use this parameter to select. ICE criteria would be take care how to deal with value

for LED modules and luminaire if you have already value of LED package lifetime but the calculation

of the LED package lifetime is still difficult.

Difficulties in quantifying and measuring LED lifetime and lumen maintenance are underlined by

stakeholders, this is the reason why a reasonable number of years of warranty can be a good

alternative. No standard method is available. For LED measurement IESNA are applicable and the

European standard will be based on that.

Few stakeholders remarked that the LED luminaires have ballast as weak point, in fact the most of

failures occur in the ballast that has to be replaced. The LED module degrades slowly it could last up

to 1000 years degrading. The welding is fragile. The warranty of 5 years is up to complete failure.

Another weak point of the luminaire is the LED quality, in fact degradation by corrosion and

degradation of the flux was observed.

A discussion on real necessity of those criteria was made between stakeholder and JRC experts,

where stakeholders remark the no necessity of having further criteria on efficiency and life time if

already the Ecodesign rules have been fixed. But JRC underlined the importance to have stricter

values in GPP as further environmental criteria.

A further criterion on the colour consistency should be introduced.

About the levels of luminaire efficacy, in Sweden they are only going to buy LED lasting 100000

hours. JRC asked if these values are verified by US standards. Stakeholder answered that the values

are L100B10 and verified by IEC 62722.

TS2 - Compatibility with dimming and other controls Proposal of technical specification for core and comprehensive criteria on dimming and controls was

presented by JRC.


A stakeholder proposed to modify the requirement and requesting to be able to dim according to the

lowest illumination class.

It was remarked that dimming doesn't provide control that is why two way communication systems

could be necessary.

The Belgian experience was reported where many municipalities switch off the lighting instead of

dimming. Conversely, in Italy per safety reasons it is not allowed to switch off completely the lighting.

A stakeholder referred to the CIE 115 standard that explains how to do.

In Italy on 17 November a new national standard on intelligent road lighting with algorithms was

proposed (dimming will be possible up to 3 classes lower).

TS3 – Product lifetime extension and TS 4 – Reparability Slides on the technical specification for core and comprehensive criteria on product lifetime

extension, warranty and reparability was presented by JRC. For Product lifetime extensions stricter

values on comprehensive criteria than the core ones are proposed.


A remark from stakeholders was about reparability in Belgium, they have 4 categories: 1, replace in

situ the bulbs, 2. Replace the driver, 3 you have to take the luminaire down to the workshop, 4-

broken you have to replace it immediately. It should be noted that sometimes you have to

disassembly the luminaire before repair. Positive feedbacks on extending the warranty were given

but some doubts on extending to 10 years availability of spare parts were raised. In fact 10 years is

quite long time for this market where technologies are changing very quickly and in the same time

what happens if the company close in ten years?

Several stakeholders strongly supported the warranty approach. It is suggested to require

maintaining available spare parts during the claimed life time of the luminaire.

TS5 – Ingress protection Slide on technical specification for Ingress protection was presented from JRC. The value proposed

was IP65 for core and comprehensive criteria.


The value proposed was considered fine for the most of stakeholders. Another proposal was to

consider the IK code for shock proof as well. In Belgium, for example, they asked for IP65 for

connection boxes, IK08 for luminaries and IK06 for protective gases.

One could add requirements to prevent aging of gaskets (standards should be selected for this).

EU GPP criteria for road lighting equipment – Light sources

Efficacy, lumen maintenance and life time of light sources Slides on the core and comprehensive criteria were presented by JRC


Also in this case particular attention should be paid to not only promote cold white light. Cold white

light presents two issues: Sky glow is proportional to the wave length (shorter means more because

the diffusion is higher): and white includes all colour and therefore maximum impact on species,

hence it maximizes.

Here it is suggested to explicitly promote LED to make the criteria easier.

Another comment, from stakeholders was on blue light that has a high impact on humans and can

contribute to visibility in scotopic luminance at very low levels.

Because in this case it was not easy to summing up all comments, it was asked to the stakeholders to

submit through BATIS their comment in written form.

Failure rate of control gear Slides on failure rate and lifetime on control gear were presented by JRC.


Because no standard are available on Failure rate of control gear or on lifetime, it was suggested to

use number of years of warranty that is easier to measure and describe.

EU GPP criteria for road lighting installation

SC - Competences of the installation team Presentation on the selection criteria for the installation team was made by JRC.


In this case the problem could be that the municipality install the lighting system themselves and in

this case public procurements occur and not even the green ones. In this case more that in design

phase providing training could be sufficient, especially tilt angle of luminaires is important. It is also

important that the design information is available during the installation

Presentation of contract performance clauses on the following topics was made by JRC

CP1 - Putting into service of lighting systems and controls Stakeholder feedback

It is important to check if there is no failing detector

CP2 – Correct installation Stakeholder feedback

The cost of measurement can be huge for small installation but it is important to have a check. For

example close the road for the measurement is a cost (complex).

A proposal could be: check of the design; and next step is measurement of illuminance at the

calculation grid. (luminance is more complex.)

AECI could be checked.

A stakeholder is going to provide cost data for the verification. Example reported by another

stakeholder mentioned 1000 euro for the verification cost. It was noted that there are also mobile

of 14

systems under development and that hence the cost of measurement in the future could become

lower.

CP3 – Reduction and recovery of waste Stakeholder feedback

One stakeholder did such a research but nothing was found for the LED component itself. For other

lamps such recycling systems are well in place.

EU GPP criteria for traffic signals JRC presented the criteria proposed related to traffic signals


The first comment was that the value 1 W proposed are offered only from Siemens and it is the only

provider. Moreover it forced to have their control system as well. It could introduce a distortion in

the market that is why the value should be checked.

It was remarked that the arrow are different for each European country. Life time related to lumen

maintenance might not fit current practice and warranty could be a better requirement to present in

the criteria.

Criteria from current criteria set proposed to be discarded. Short presentation on the criteria that are still in the current GPP 2012, and are going to be discarded

in the new proposal.


The size of the package could be limited? The size is needed for cooling and hence it is not a good

idea to limit it. Maybe a dimming curve could be added.

After a short summary of the meeting from JRC and a reminder to submit the comments through

BATIS system by the 23rd of January 2017, the meeting was closed at 17:45.
