Environmental impacts How do street lighting (light, ballast, control gear, luminaires) impact the environment? Carbon emissions: over 90% of environmental impact from energy consumption and associated GHG emissions occur in the use phase Poor resource efficiency Impact on wildlife species and light pollution Estimated energy consumption in 2005 for street lighting was 35 TWh for the EU25, representing approximately 1.3% of the final energy consumption of electricity in the EU25 Environmental impacts include: CO2 and other greenhouse gas emissions and acidifying gases as a result of electricity consumption in the use of road lighting. Loss of star visibility caused by upward light output from unshielded luminaires and reflection from the ground. Disruption of nocturnal species’ behaviour (because of blue light’. Poor resource efficiency in cases where products or components need to be replaced before the end of their stated lifetime EuP Lot 9 Study: Public Street Lighting, VITO, January 2007.

Module 7.8 – Road lighting and traffic signals Needs Assessment Assess the need for new installation or renovation of the existing lighting infrastructure Three key questions: After evaluating actual needs based on the status of the plants, light pollution and safety, is a new plant necessary? Can renovation of the existing plant ensure energy savings and reduce the environmental impact throughout the life cycle of the road lighting system? Can the safety of circulation be improved by creating complementary or alternative lighting works such as signage, retarders, bollards, etc.?

Module 7.8 – Road lighting and traffic signals EU GPP Criteria Road Lighting and Traffic Signals (2018) Examples: Selection criteria (SC) – design team and installation team shall have relevant competencies and experience Technical specifications (TS) – the lighting equipment to be installed shall have a luminaire efficacy higher than the relevant reference value stated Award criteria (AC) – points awarded to tenderers that are able to provide light sources or luminaires which exceed the minimum luminous efficacy defined in the technical specifications Contract performance clauses (CPC) – contractor shall ensure that new or renovated lighting systems and controls are working properly For full criteria see: EU GPP Criteria for Road lighting and traffic signals For each subsets of products and works contracts EU GPP criteria are divided into: Selection criteria – used to assess the ability of an operator to perform a contract. Can only include criteria specifically related to the subject matter of the contract. (Road lighting example – design team and installation team shall have relevant competencies and experience) Technical specifications – used to set minimum requirements that must be met by all tenders. Must relate to the characteristics of the work, supply or service being purchased. (Road lighting example – the lighting equipment to be installed shall have a luminaire efficacy higher than the relevant reference value stated) Award criteria – used to stimulate additional environmental performance, but are not mandatory. (Road lighting example – points awarded to tenderers that are able to provide light sources or luminaires which exceed the minimum luminous efficacy defined in the technical specifications)  Contract performance clauses – specify how a contract must be carried out. Relevant to service contracts. (Road lighting example – contractor shall ensure that new or renovated lighting systems and controls are working properly) For each set of criteria there are two levels of ambition: Core – designed to allow easy application of GPP, focussing on the key area(s) of environmental performance of a product and aimed at keeping administrative costs for companies to a minimum (road lighting example – 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). Comprehensive – take into account more aspects or higher levels of environmental performance, for use by authorities that want to go further in supporting environmental and innovation goals (road lighting example – Minimum dimming performance: All light sources and luminaires shall be installed with fully functional dimming controls that are programmable to set at least two pre-set levels of dimming, down to at least 10 % of maximum light output).

Module 7.8 – Road lighting and traffic signals Verification Checking compliance with GPP criteria What to ask for? When? Standard photometric file calculated according to EN standards technical specifications on the light output and energy consumption documentation from the manufacturer(s) lighting software used to calculate technical specifications of the metering and measurement system declaration of compliance tests carried out in accordance with IEC 61000-3-2 light spectra of all lamps Compliance with GPP criteria needs to be assessed both at the time of selection of best offer and during the contract execution phase and commissioning. Verification systems are product-specific. They include different requirements and may consist in the submission of existing documentation that the supplier has at their disposal and of specific documentation to be produced to prove compliance with an environmental requirement. Each criterion has its own corresponding verification that must always be included in the tender documentation. Procurers should also make clear what needs to be verified during the evaluation and selection stage and what needs to be verified during contract execution.
