Strategy Figures:
Total Savings & Costs: Public Street Lighting
(2010 Sustainable Lighting Strategy – Whole Emirate; all roads)
 Use of LED technology & lower luminances gives a 67% reduction in energy usage &
CO2 emission reduction vs. existing (conventional HPS) Abu Dhabi installations
 Proposed Lighting Strategy is 35% cheaper than existing standards/ technology over
20 years analysis considering energy economic cost, achieving an overall saving of
AED 1.13 Billion

Some Project Verification Examples

Sector E48 has 114 new LED fixtures and poles and is the first Inner-Sector street project to be completed to the new 0.6CDm
2 luminance level set by the Sustainable Lighting
Strategy and shows how this new level and lighting design standards combine to result in a clear, safe and quality lighting scheme which was estimated at being 76% more efficient than the conventional discharge lighting approach.

ADM obtained as many of the
Lighting Control Cabinet meter readings from ADDC that were available for the sector from before LED lighting was installed and afterwards

New roadway lighting design level was approximately 40% lower for this Major Arterial and the use of LED technology was implemented throughout for the first time in Abu Dhabi. Highly efficient lighting fixture optics were utilised to ensure light is focused only where it needs to be avoiding wasted light and reducing light pollution. This further maximizes the overall lighting efficiency of roadway lighting installations.
Street – 660 LED fixtures, Tunnel – 5,500 LED fixtures

2011 to 2014 Installations - Performance Summary
1/ Energy Consumption Savings & Costs :
 All lighting control cabinet records and on-site electrical current-meter readings show that the LED fixtures/circuits draw near-identical loads to those used in all design calculations.
(As DMA Specifications only allow Accredited Internationally Certified LED fixture test data for all installed fixtures, this should always be the case)
2/ LED Fixture Performance :
 Light Output always measured on site against calculations using both luminance and LUX meters and match on all projects to date. After 12-months, new Lux readings taken to check depreciation is within limits and all projects are exceeding expectations.
3/ LED Fixture failures :
 Normally 0.5 to 1% of all lighting fixtures are expected to be faulty on any project in some form, then needing replacement under warranty. However for all ADM projects, there has not been a single failure of any LED fixture for over a 12,000 units. This again exceeds expectations.

Key New Project Example – KCA (HPS vs. LED)
New lighting provision to all the city’s Inner Sector roads (Project at Tender)
• KCA currently has only Main Road lighting infrastructure with HPS provided
• New Inner Sector Street lighting with LED Tendered under 3-Zone packages. Retrofit of Main
Road HPS to LED proposed in 2015 under separate works package

Revision 2 of the DMA Lighting Specifications

Revision 2 of the DMA Lighting Specifications

Revision 2 of the DMA Lighting Specifications – Why?
• Easier to follow format with more concise and logical sections and setting-out of clauses
• Necessity to update the performance benchmarks and design criteria for LED (and other allowable) lighting technology: Relaxation of some criteria, some tightening on others
• Alignment with ADQCC, ESMA, Estidama and other stakeholders
• Refining some of the lighting design criteria for both roads and parks/public realm
• Additional new Standards regarding solar street lighting technology, design, project cost analysis and application. Refined solar criteria for public realm also
• New requirements regarding signage lighting and aligned standards for the avoidance of project light pollution and glare
• Revised and expanded criteria for dimming/lighting controls including statutory project requirements and area-specific dimming levels
• New national & international standards need to be updated/incorporated. Errors corrected
• New section for Project Submission requirements , material and methodology

The ESMA Lighting Regulations (Primarily Lamp Regulations)

The QCC Conformity Scheme for External LED Luminaires

Revision 2 of the DMA Lighting Specifications
• Necessity to update the performance benchmarks and design criteria for LED (and other allowable) lighting technology: Relaxation of some criteria, some tightening on others.
Summary of some key changes:
1/ Adherence to new ESMA regulations where applicable for fixtures/lamps
2/ New Clauses will state all LED fixtures to have the ADQCC Quality mark in future
The Revision-2 DMA Specifications and ADQCC scheme will be technically aligned
This means that many test sheets covered under the QCC quality scheme will not need to be submitted each time on projects, simplifying the submission process to just the specific DMA
Specification brief items only
Note. Understanding that there will be a transition period for taking up and completing the certification of ranges, if the QCC process is not complete then, for 12-months:-
1/ A copy of the ADQCC application/receipt needs to be provided with project submissions
2/ All the relevant technical luminaire test information must be submitted as part for the project submission process

Revision 2 of the DMA Lighting Specifications
• Easier to follow format with more concise and logical sections and setting-out of clauses

Revision 2 of the DMA Lighting Specifications
• Easier to follow format with more concise and logical sections and setting-out of clauses
ADQCC Certification to Preclude

Revision 2 of the DMA Lighting Specifications
• Necessity to update the performance benchmarks and design criteria for LED (and other allowable) lighting technology: Relaxation of some criteria, some tightening on others.
Summary of some key changes:
3/ Warranty , material and thermal testing still based at 50 0 C ambient operating, but efficacy figures and lifetime performance (lumen depreciation) based on luminaire 35 0 C ambient.
( allowances for tunnel fixtures will be different )
This is because lifetime lumen performance of LEDs is accumulative over the hours of their operation, therefore average temperatures can be used for more appropriate estimation.
Five-year annual temperature records (taken at Abu Dhabi Airport specifically)
Contain information on average annual high temperature (at just under 35 0 C) and average lows of somewhere around 23 0 C. Average nighttime temperatures will be assessed and will be somewhere within this band.

Revision 2 of the DMA Lighting Specifications
• Necessity to update the performance benchmarks and design criteria for LED (and other allowable) lighting technology: Relaxation of some criteria, some tightening on others.
Summary of some key changes:
4/ Some Colour rendering and binning changes: For street lighting for example, the minimum
Ra drops from 70 to 65 and the MacAdam Step allowance up from 4 to 5.
This is because the future LED chips hitting the marketplace will be more applicationspecific and the chip manufacturers are producing chips targeted for street lighting luminaires and designed to be ‘bin-free’ all within Step-5 and at Ra65/70 depending on manufacturer
This cannot be ignored and essentially dictates the international benchmark for what is generally accepted as optimum for street lighting applications.
Similar application-specific chips are now being targeted for commercial/retail application fixtures, museum (Step-1, high Ra) applications and domestic lamps/products.

Extreme Colour Temperature Requests - Warning!
The American National Standards Institute (ANSI) publishes Chromaticity Standards for all
LED light sources and define just eight ‘nominal’ CCTs ranging from 2700K to 6500K (ultrawarm to daylight white).

Revision 2 of the DMA Lighting Specifications
• Necessity to update the performance benchmarks and design criteria for LED (and other allowable) lighting technology: Relaxation of some criteria, some tightening on others.
Summary of some key changes:
5/ Maximum copper content allowance for cast aluminium increased to 1% from 0.1%
6/ Written confirmation that Mesopic multipliers are not allowed. All projects are to assume an
S/P ratio of 1.00 for all luminaires regardless of claims
7/ Project Efficacy - Power Density calculations will be required: to prove schemes are within
set wattage/(cd/m2*m2) limits as per EN-1320
8/ Incorporation of TM-21 and LM-82 assessment for lifetime prediction
9/ For street lighting and tunnel lighting fixtures, minimum 10-year full warranty required.
Fixtures for parks/public realm projects will remain as current specification
