PRIMES Street lighting components The most predominantly used lamps in street lighting are high-intensity discharge lamps (HID) that include:  High-pressure sodium lamps  Metal halide lamps with quartz arc tube  Metal halide lamps with ceramic arc tube  Low-pressure sodium lamps  High-pressure mercury lamps © Photo courtesy of khunaspix by digitalfreephoto.net

PRIMES Environmental impacts by street lighting  Energy consumption, in all phases, but especially the use phase of street lighting and traffic signals  High energy consumption from the use of incandescent bulbs in traffic signals  Use of natural resources and materials and generation of waste (hazardous and non-hazardous)  Potential pollution of air, land and water due to the use of hazardous materials e.g. mercury  Light pollution from street lighting © Photo courtesy of askpermission by ICLEI

PRIMES GPP criteria to approch environmental impacts  Purchase lamps with high lamp efficacy  Purchase efficient ballasts  Promote the purchase of lighting systems with a low energy consumption for the light provided  Promote the use of LEDs in traffic signals  Encourage the use of dimmable ballasts where circumstances allow  Promote lamps with a lower mercury content  Promote the use of luminaires that limit light emitted above the horizon © Photo courtesy by ICLEI

PRIMES Applicable EU Directives  Directive 2009/125/EC establishing a framework for the setting of eco-design requirements for energy-related products  Regulation (EC) No 245/2009 with regard to eco- design requirements for fluorescent lamps without integrated ballast, for high intensity discharge lamps, and for ballasts and luminaires able to operate such lamps, repealing Directive 2000/55/EC and Regulation 347/2010  Directive 2006/32/EC on energy end-use efficiency and energy services © Photo courtesy of ICLEIbooklet by ICLEI

PRIMES Cost considerations  Street lighting provides maximum energy savings at reasonable capital costs, when the contracting authority considers GPP specification and the best available fittings for new lighting systems and refurbishment of existing systems  Where fittings allow, more efficient lamps should be used depending on the location and specific light use requirements  Need to meter electricity consumption for street lighting as cost of electricity is calculated based on the number of units and their nominal wattage, multiplied by the number of hours of use, i.e. where street lighting is upgraded to improve energy efficiency, the contracting authority should seek to renegotiate the electricity charges © Photo courtesy of Invisibleviva_dreamstime by ICLEI

PRIMES Cost considerations  Good street lighting design may be able to reduce costs by the resulting increase in distance between the streetlights and lower lamp power.  Using lamps that have longer lifetimes and better lumen maintenance will result in longer maintenance times, there fore reducing costs. This will also reduce the indirect impacts incurred through replacement and maintenance, such as vehicular emissions and the associated impacts from manufacturing and distributing more components, mainly lamps. © Photo courtesy of Invisibleviva_dreamstime by ICLEI

PRIMES Recommendations: Technicial Specifications (2)  Where a new lighting system is being provided for a traffic route (classes ME or MEW in EN ), the maximum energy efficiency indicator, must not exceed specified values  Where a new lighting system is being provided for a conflict area (e.g. road intersection, shopping street, residential road, pathway or cycle track) (classes CE or S in EN ), the maximum energy efficiency indicator, must not exceed specified values  Luminaires shall be designed and installed to ensure that ULR, the proportion of light emitted by the luminaire going above the horizon is limited as specified, without detriment to the overall energy efficiency of the system for which it is designed

PRIMES Recommendations: Technicial Specifications (2)  Where lighting is to be installed in an individual space or part of the building, the maximum lighting power consumed in the space, divided by its total floor area and by its illuminance in units of 100 lux, must not exceed the given values  Design and installation of lighting controls for infrequently occupied spaces, spaces which are unoccupied at night or at weekends, spaces with side windows to be controlled in rows parallel to the windows, in offices, conference rooms, school classrooms and laboratories, in daylit circulation areas and reception areas to be controlled by automatic daylight linked control

PRIMES Recommendations: Technicial Specifications (3)  The tenderer shall provide the following for new or renovated lighting systems  Disassembly instructions for luminaires  Instructions on how to replace lamps, and which lamps can be used in the luminaires without decreasing the stated energy efficiency  Instructions on how to operate and maintain lighting controls  For daylight linked controls, instructions on how to recalibrate and adjust them.  For time switches, instructions on how to adjust the switch off times, and advice on how best to do this to meet visual needs without excessive increase in energy consumption

Budapest, Hungary Best practise example Introduction  Green Programme of Budapest was created in 2002  Own GPP criteria developed in 2006  Procurement process was launched to install lighting that would fit the aesthetics of the bridge, allow for the safe transit of trams, cars and pedestrians and withstand humidity and heavy vibrations. The sustainability and cost of the lighting solution were key concerns for the city  Call for supply and installation of ornamental and street lighting on Liberty Bridge © Photo courtesy of caminoel by digitalfreephoto.net

Budapest, Hungary Best practise example Technical Specifications The required levels of lighting for carriageways and footpaths were specified, with reference to standard EN or equivalent. The quantities of luminaries, lamps and supports were set out in a schedule, along with the specific design and durability requirements identified.  Lumen efficacy (based on the ratio of power input to visible light output)  Ballast efficiency (based on the ratio of ballast output to lamp-ballast circuit input) © Photo courtesy of caminoel by digitalfreephoto.net

Budapest, Hungary Best practise examples Results  More than 800 light fittings installed, incl. 584 LED lights equaling installed power of 40.7 kilowatts (LEDs account for 13.1 kilowatts)  Project carried out in 2009 at a cost of €1.66 million  Estimated life expectancy of the ornamental lighting installed is 15 years and 30 years for the street lighting; this longer lifespan means lower replacement rates, bringing considerable direct and indirect economic benefits and reduced waste  Normally replacing lamps is difficult and costly due to mounting on the bridge and the disruption to traffic: avoiding of these costs  Savings on electricity compared with the original concept estimated at €40,000 per annum, with total savings of € per annum © Photo courtesy of caminoel by digitalfreephoto.net
