5 Sustainable Lighting Strategy The Key Factors Abu Dhabi Sustainable Reduce all Roadway and Pavement lighting levels and ensure more targeted design for both Roadway and Pavement lighting Ensure Parks and Public Realm projects are designed with suitable lighting for long-term efficiency and quality for the environment and people Specify energy and optical efficient quality LED and other new low-energy technology and appropriate controls for all uses Introduce Emirate-specific Performance Benchmarking system for and LED and new technologies for external lighting Mandate Policy to include statutory brightness hierarchy and design guidance for all external public lighting. Align with other AD documents e.g. Estidama Return maintenance of all road lighting back to asset owners (Municipalities, and DoT) Explore energy-saving and step-dimming systems for traditional technology high-mast road lighting. Maintain ongoing research analysis 5

29 How to specify LEDs for the Extreme Environment of the Middle East What are the issues with LEDs for use in the Middle East? Temperature? Humidity? Dust? Sand? Corrosion? Performance? Drivers? Answer is: QUALITY fixtures & lighting design address all the above There are no issues in specifying LEDs for Middle East external use...if Correct technical LED Specifications are written and enforced Correct lighting design criteria/standards/brief are issued Consultant/Designers are required to Specify and Design correctly Specifications and Standards are enforced through all project stages Any Equal & Approved submissions and/or value engineering is monitored and controlled 29

30 LED Fixture Specification The key areas to define with benchmarks/criteria LED Fixture efficacy LED Fixture thermal design LED Fixture testing performed at actual local maximum nighttime temperature/humidity, plus safety factor Storage (or daytime) temperature tolerance of components and fixtures LED source colour temperature and rendering LED chip binning Driver specification IP, IK rating & corrosion/environmental resistance Photometry Useful Life calculation criteria Photobiological safety Long warranties 30

31 LED Fixture Specification LED Fixture efficacy Whole Luminaire Efficacy: The optimum efficiency of the luminaire shall be confirmed as follows: Minimum luminaire efficacy shall be: 75llm/cctW min95%rh Which is given as Total Luminaire Design(Deliver) Lumen Output (llm) over Total Luminaire Circuit Watts(cctW) at minimum 50-degrees Centigrade Operating Outside Ambient Temperature and minimum 95% Relative Humidity. The efficacy being stated at minimum 50 Deg C (Greater than or equal to 75 llm/cctw) should be supported by a thermal test report for the luminaire. This report should provide percentage depreciation of light output at 50 Deg C from testing value of 25degreeC or 35degreeC. This can be compared with LM-79 efficacy at lab temperature from photometric report and de-rated. The effect on the driver case temperature at minimum 50degreeC should also be shown. 31

34 The Policy is being implemented by DMA/ADM through new stringent Lighting Specifications and tables of lighting design criteria have been written and being applied on all current and future projects. The Policy will be expanded into a comprehensive Abu Dhabi Sustainable Public Lighting CODE document to offer best practice design advice as well as standards and statutory criteria. 34

35 35

36 The Tables of New Lighting Strategy Reduced Roadway Illuminances has been now issued under DMA Decree-39 36

37 37

38 All new Public Realm projects are being designed fully in accordance with the Lighting Strategy requirements on both ensuring balanced illumination levels and lighting quality of the designs 38

39 39

40 The Specifications have now become DMA Specifications and officially issued under the DMA Decree-39 to cover the whole Emirate: All Municipalities, DoT and Developers have to adhere. 40

41 The Current Lighting Strategy and Specification Documents Will be Expanded into a National Statutory Design Guidance CODE Document Typical International Exemplar Documents: 41

44 Al Salam Street Sustainable LED Lighting Installation The roadway, tunnel and traffic signal lighting for the Salam Street project is all undertaken for the first time in the region utilizing LED technology throughout. This was undertaken as part of the DMA/ADM Sustainable Lighting Strategy to provide the best possible long-term sustainable lighting solution

45 Al Salam Street Sustainable LED Lighting Installation The new roadway and tunnel lighting levels are approximately 60% lower across all road categories and the use of LED efficient long-life 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 45

46 Al Salam Street Sustainable LED Lighting Installation 46

47 Al Salam Street Sustainable LED Lighting Installation Salam Street s LED signals draw approximately 80% less power than traditional incandescent signals, last around 8-times longer and the loss of individual LEDs will not lead to a total loss of the indication, maximizing safety at intersections. The combination of the LED road, tunnel and signal lighting systems provides a virtually maintenance free installation for the whole of Salam Street; a solution that is now being applied throughout the city of Abu Dhabi 47

48 Al Salam Street Sustainable LED Lighting Installation The Municipality of Abu Dhabi City s Salam Street project recently won the prestigious Green Initiative Prize at the 2011 Gulf Traffic Awards as well as winning the Project of the Year Category at the 2012 Middle East Electricity Awards. 48

49 Sheikh Zayed Bridge Lighting As part of the Abu Dhabi Gateway project, the new Sheikh Zayed Bridge has been lit with a sustainable long-term roadway and architectural lighting system to both enhance the form of the flowing structure, representing undulating sand dunes, but also is programmed with special scenes for occasions and importance dates within the UAE without ever needing to bring in and connect additional lighting equipment Nominated for the 2012 Lighting Design Awards Best International Exterior Project

50 Sheikh Zayed Bridge Lighting 50

51 Sheikh Zayed Bridge Lighting The lighting scenes comprise of dynamic coloured light that smoothly flows across the Maqtaa channel 51

52 Sheikh Zayed Bridge Lighting A system of special targeted energy efficient roadway and architectural fixtures have been designed to avoid light spill, with light applied only where needed. The architectural lighting is able to produce any of 16 million colours with a DMX lighting control system to program and sequence the effects on the bridge and also ensure all effects are tuned off from 1am until dawn for maximizing the efficiency and lamp life of the installation 52
