GPP criteria for road lighting and traffic signals Green Public Procurement environment.gov.mt

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: Low light Good quality Energy efficient pollution and durable lighting lighting lighting equipment equipment equipment
Energy efficient lighting equipment: Luminaire efficacy Dimming control compatibility Minimum dimming performance Annual energy consumption indicator Metering Power factor
Luminaire efficacy • Government institutions are obliged, under Article 6 of the Energy Efficiency Directive, to purchase only Year of ITT Efficacy (lm/W) products that comply with energy efficiency benchmarks. 2018-19 120 • With regards to road lighting, 2020-21 137 Regulation 245/2009 is currently in force and will be later repealed by a 2022-23 155 new Commission Regulation.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.
Minimum dimming performance • All light sources and luminaires shall be installed with fully functional dimming controls that are programmable to set at least one pre-set level of dimming down to at least 50 % of maximum light output .
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 2 nd NAP.
Metering A metering system for a road lighting network may play a strategic role in energy consumption and CO 2 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.
Low light Good quality Energy efficient pollution and durable lighting lighting lighting equipment equipment equipment
Low light pollution lighting equipment: • Ratio of Upward Light Output (RULO) and obtrusive light • Annoyance • Ecological light pollution and star visibility
(RULO) and obtrusive light The central argument for having criteria that limit the upward light output 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 only 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.
Ecological light pollution and star visibility • 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.

• 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 of 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)
