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

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

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.

protection rating

PRIMES Recommendations: Technicial Specifications (2)

Where a new lighting system is being provided for a traffic route

(classes ME or MEW in EN 13201-1), 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 13201-1), 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

PRIMES Ecolabels and existing standards

No specific Ecolabels at present

Several countries have labels and/or minimum

energy performance standards for various

components.

Ecolabels that do exist are applicable to fluorescent

tubes and compact fluorescent lamps, and not HID

lamps Energy Efficiency Index for Ballasts – CELMA, Europe

Ecolabels applicable to types of lighting outside the

scope of this GPP product group. In particular these

cover general lighting products for use in domestic

and small commercial situations and focus mainly on

compact fluorescent lamps

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

Budapest, Hungary Best practise example

Technical Specifications

The required levels of lighting for carriageways and footpaths were

specified, with reference to standard EN 13201 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)

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 €100.000 per annum
