3. PRIMES Indoor lighting facts  Almost all public buildings require indoor lighting:  For an entire building (new or completely refurbished)  For a space/set of spaces (refurbishment of part of a building, an extension to an existing building)  Replacement of luminaires within a space/s, while keeping wiring and lighting controls  Retrofit lighting controls, while keeping luminaires.  Replacement of lamps  Additional lighting (e.g. desktop task lighting, display lighting). Often such lighting is portable and plugs into electric sockets  Replacement of lamps form the majority of regular procurement © Photo courtesy of EC by http://ec.europa.eu/environment/gpp/pdf/tbr/indoor_lighting_tbr.pdf

4. PRIMES Public Procurement and products with high environmental leverage

5. PRIMES Indoor lighting components  Lamps and ballasts (Fluorescent lamps, Tungsten halogen lamps, LED lamps, High-pressure discharge lamps)  Luminaires (light fittings): Lamps are generally used inside a fitting or luminaire, and this can also have a major impact on the performance of the overall lighting system  Lighting controls: Controls allow the building occupants to switch off or dim lighting when it is not required © Photo courtesy by ICLEI

6. PRIMES Environmental impacts by indoor lighting  Energy consumption, in all phases, but especially the use phase of indoor lighting  Potential pollution of air, land and water during the production phase  Use of materials and hazardous materials  Generation of waste (hazardous and non-hazardous) © Photo courtesy of askpermission by ICLEI

7. PRIMES GPP criteria to approch environmental impacts  At design stage, ensure new lighting installations have low power density meeting visual task requirements  Purchase replacement lamps with high lamp efficacy  Use lighting controls to further reduce energy consumption  Encourage the use of dimmable ballasts where circumstances allow  At installation stage, ensure system works as intended, in an energy efficient way  Promote lamps with a lower mercury content  Reuse or recover installation waste © Photo courtesy by ICLEI

8. 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 © Photo courtesy of ICLEIbooklet by ICLEI

9. PRIMES Applicable EU Directives  Directive 2006/32/EC on energy end-use efficiency and energy services  Directive 2010/31/EC on the energy performance of buildings: Minimum energy performance requirements for new buildings and for large existing buildings when they are renovated, and to introduce energy certification schemes for buildings. The energy performance is calculated using an approved methodology and includes, amongst other things, the effects of natural light and built-in lighting installations

10. PRIMES Cost considerations  The cost is dominated by energy cost: Usually cost effective to use a more expensive luminaire even if only 10-20% more efficient. Using more efficient luminaires can sometimes allow fewer luminaires to be installed, saving capital outlay  Energy efficient lamps last longer than their tungsten and tungsten halogen counterparts, saving on maintenance costs as well as on energy consumed, also saving on staff costs replacing lamps regularly  The automatic lighting controls may save 30-40% of electricity cost with no additional capital cost (payback period of 2-4 years when retrofitting) (Controls can provide energy savings even if lighting is switched off for only short periods) © Photo courtesy of Invisibleviva_dreamstime by ICLEI

11. PRIMES Life-Cycle Costing  LCA should include the initial cost of the installation, its estimated lifetime, replacement costs of lamps and their estimated life, and energy cost of the lighting over its lifetime.  The contracting authority will need to define its electricity price and the rate at which this increases, and its interest rate on investments (e.g. Swedish Environmental Management Council’s Procurement Criteria for Indoor Lighting Products) © Photo courtesy of Invisibleviva_dreamstime by ICLEI

12. PRIMES Recommendations: Subject Matter Include sustainability aspects within the subject Matter (‚GPP Training Toolkit‘)  Purchasing of resource and energy efficient lamps (1)  Resource and energy efficient design of new lighting systems or renovation of the existing lighting system (2)  Resource and energy efficient installation of new lighting systems or renovation of the existing lighting system (3) Source: © Image courtesy of ponsulak at FreeDigitalPhotos.net

13. PRIMES Recommendations: Technicial Specifications (1)  Replacement lamps for existing installations shall have a lamp luminous efficacy equal to or greater than the minimum efficacy of the given relevant energy class  Lamps for new and renovated installations shall have a lamp luminous efficacy equal to or greater than the minimum efficacy of the given relevant energy class  Lamps for new and renovated installations, and replacement lamps in existing installations, shall have a lifetime not less than that given in the table below

14. PRIMES Recommendations: Technicial Specifications (2)  Installation throughout a building, the maximum lighting power consumed in the whole building, divided by its total floor area, must not exceed given values  Installtion in an individual space/part of a 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 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

15. PRIMES Recommendations: Technicial Specifications (3)  The tenderer shall provide the following for new or renovated lighting installations  Disassembly instructions for luminaires  Instructions on how to replace lamps, and which lamps can be used in the luminaires without increasing the stated power densities  Instructions on how to operate and maintain lighting controls  For occupancy sensors, instructions on how to adjust their sensitivity and time delay, and advice on how best to do this to meet occupant needs without excessive increase in energy consumption  For daylight linked controls, instructions on how to recalibrate and adjust them, for example to take into account changes to room layout.  For time switches, instructions on how to adjust the switch off times, and advice on how best to do this to meet occupant needs without excessive increase in energy consumption  The tenderer shall implement appropriate environmental measures to reduce and recover the waste that is produced during the installation of a new or renovated lighting system.

16. PRIMES Recommendations: Award Criteria (1)  Award will go to “Most economically advantageous tender (MEAT)”  Credit will be awarded if lamp luminous efficacies are at least 110% of the minima given in the relevant table for criteria 1A or 1B above  Credit will be awarded if lamp lifetime is at least 120% of the minimum given in the table for criterion 2 above.  Credit will be awarded if lamp mercury content is at most 80% of the maximum given in the table for criterion 3 above.

17. PRIMES Recommendations: Award Criteria (2)  Award will go to “Most economically advantageous tender (MEAT)”  Where dimming would be beneficial: To count as dimmable, lighting has to be controllable automatically so that early in the life of the installation (lamps/ luminaires still clean and bright) the lighting can be dimmed to provide the required maintained illuminance; and if the space is daylit, automatic daylight linked dimming is to be provided  Credit will be awarded if power densities are less than 90% of those criteria given or alternatively if normalised power densities are less than 90% of given criteria Source: © Image courtesy of Stuart Miles at FreeDigitalPhotos.net

18. PRIMES Ecolabels and existing standards  Existing Ecolabels specific for indoor lighting usually apply to compact fluorescent lamps, LED lamps and fluorescent tubes but not HID lamps  Many countries have labels and/or minimum energy performance standards for various components of indoor lighting, focussing mainly on the ballasts

19.
