Where the total lighting installation needs to meet tight project budgetary constraints, then both

LED options and traditional energy-efficient technology fixture options shall be tabled to either therelevant Municipality or DoT with full comparison costings and technical data in order for the finaldecision to be made.

The additional technical specification requirements for LED fixtures necessary to ensure qualitysolutions are proposed is detailed within this specification alongside the basic lighting specificationand design requirements.

Solar Lighting Requirements

2 The DMA/DoT strives to be a leader in sustainability and as part of this aim it is required that forevery park and public realm lighting project the Consultant shall explore the current viability and

options for solar lighting solutions in the marketplace and propose where best it can be offered forincorporation into the project.

Particular attention should be paid to areas of the project which might provide specific advantagesfor having some solar lighting technology and/or their cost of implementation can be mitigated byother factors. These include, but are not limited to, interactive/awareness zones, integrated withlocal structures, isolated areas without current electrical infrastructure, dedicated sports areas,children’s play areas, sculptures/arts or specific paths.

Either the relevant Municipality or DoT may require detailed cost/payback analysis to develop anyapproved options through to Detailed Design and Tender Issue.

41 Architectural Floodlighting

The illuminance requirements for open public realm spaces such as public squares and parks aregiven in the above tables. Precise requirements for the architectural illuminance of buildings,facades and structures cannot be given so specifically because the values are affected by manymore variables. However, the general recommendations of the below table are a useful startingpoint and are DMA/DoT maximum average illuminance limits for design. Better design criteriashould be obtained and provided to either the relevant Municipality or DoT on the reflectance of thesurface material, its state of cleanliness and the district brightness; it is assumed that the buildingsurface is reasonably matt; specular finishes will require additional special consideration.

Successful building floodlighting depends on much more than achieving the recommendedmaximum average illuminance and there is only an indirect relationship between illuminance,luminance and the visual effect produced.

The simplified procedure comprises of 5 steps:

Determination of required illuminance;

Choice of lamps and floodlights best suited to the project;

Calculation of the number and wattage of floodlights and/or architectural feature lightsneeded to give the required illuminance;

Determination of best mounting positions for floodlights;

Specification of aiming directions for the floodlights.

*Based on reflectance for a white light. Values will need to be adapted for light sources with adefined colour, illuminance shall then be defined in accordance with clause 40 and be decided with

site trials/mock-ups.

**Typical districts are: Low Brightness – Rural, Medium Brightness – Suburban, High Brightness –Town and City Centres. Refer also to the requirements of Estidama.

42 Coloured Light Conversion Factors when using Filters

It is important to remember that the colour of surface material is accentuated if light of the samecolour is used. Also attractive effects are sometimes achieved by using light of different colours atdifferent times and/or in specific locations. The following table gives the factors by which thecalculated illuminance based upon white light, has to be increased in order to achieve the sameapparent value visually where coloured filters are proposed. These factors take into account thefact that coloured light is more conspicuous but also the transmission losses of different filtercolours.

Where ever colour is proposed these are only general guidelines and it is always suggested to useactual filter transmission values, physically test and if necessary mock-up the proposal before

finalizing the design and fixture specifications.

.

43 Coloured Light when using Coloured and RGB LEDs

Coloured LEDs, emit coloured light directly from the chip without additional filtering required. Assuch the values obtained within lighting design software from luminaire photometry can accuratelycompared against white light fixtures and the resultant illuminance and luminance figures a goodguide to effectiveness.

Conversion factors do not need to be applied as the outputs in all colours is achieved at 100% ofthe rated outputs. However it is always suggested to physically test and if necessary mock-up anycoloured lighting solutions within the proposal before finalizing the design and fixture specifications.

Project Lighting Calculations - The following performance reports of the lightinginstallation shall be submitted for approval along with the material submittal:

illuminance and meet lighting criteria. Determination of best mounting positions for luminaires; Specification of aiming directions for the luminaires.

Project Lighting Calculations - The following performance reports of the lightinginstallation shall be submitted for approval along with the material submittal:

40 Computer Generated Photometric Analysis of Proposed DAY 1 (Defined as the initial illuminancevalues):

This calculation is useful to ascertain the expected measurable light levels on site during the projectcommissioning period. It should be noted that this is not considered a design calculation for theproject. The design calculation is undertaken in accordance with section 41 below.

a/ Provide average luminance/illuminance measurements and uniformity at grade. Spacingbetween measurement points shall be as per CIBSE, CIE or IESNA standards or equivalent

European or International Standards and standard software settings.

b/ Computer calculations should use of the following applicable LLF value (in accordance with themethodology set out in section 36 above): using variables 1.0 for both LLD and for LDD.

c/ The photometric data files shall be provided to either the relevant Municipality or DoT forverification.

41 Computer Generated Photometric Analysis of Proposed FUTURE DATE (Defined as assumingnumerous thousands of hours of operation and using stated design/deliver illuminance values).

This calculation is considered the DESIGN calculation for the project.


b/ Computer calculation should use the LLF values (LLD x LDD). All as calculated under therequirements set out in section 36 above.

c/ The photometric data files shall be provided to Consultant and either the relevant Municipality or

DoT for verification.

Quality Assurance

42 Either the relevant Municipality or DoT may request standard production model luminaire samples,identical (including lamp/LED light source and control gear/driver package) to the proposedspecified product, to be installed for inspection. The Municipality or DoT may also requestindependent testing of sample luminaires to verify luminaire performance and compliance with thespecifications. Testing shall be conducted as per the applicable IESNA, ANSI or approvedInternational equivalent and international approved methods of products using Solid Stage Lighting(SSL - LED) sources. The relevant Municipality or DoT shall be sole judge regarding acceptabilityof optical system performance. All testing certificates shall be from a Laboratory certified/approvedby UKAS or UL or has ISO 17025 or equivalent certification.

According to the requirements of the Project’s Contract documents, if required either the relevantMunicipality or DoT reserves the right to attend, or appoint a third party to attend, a factoryinspection.

Warranty

Luminaire Warranty - The Consultant/Contractor shall provide a written undertaking of theWarranty from the Luminaire Supplier(s), accompanied with the written proof of the localrepresentative’s UAE Operating License and established UAE background, to the satisfaction ofeither the relevant Municipality or DoT to warranty the materials and performance, as follows:

43 A written warranty for a minimum five (5) year on-site replacement material, fixture, finishes andworkmanship. On-site replacement includes transportation, removal and installation of newproduct. Body and finish warranty shall include warranty against failure or substantialdeteriorations such as corrosion, blistering, cracking, peeling, chalking or fading with no cost to theMunicipality/DoT.

44 For LED fixtures a written warranty for a minimum five (5) year replacement material warranty fordefective or non-starting LED source assemblies with no cost to the Municipality/DoT.
