SLQS JOURNALLeed and Pearl Rating System in the UAEJanuary 2009Dammika Kumari MSc, Member APQSE, ACIOB, AACEhas successfully completed her National Certificate of Technology in Quantity Surveying course in the Universityof Moratuwa in 1985. She has joined M/s Vasiri Constructions (Pvt) Ltd. Sri Lanka as a Senior QuantitySurveyor and was promoted up to a Director. Dammika joined with D G Jones and Partners (Middle East)Limited of Dubai in 2004. She has obtained her Master of Science in Quantity Surveying from Heriot WattUniversity of Scotland in 2008 as the first lady student from Asia.UAE’s construction industry is considered to be the largestgrowing industry in the Gulf Region. The Emirate of Dubaiin the UAE has been identified as one of the top ten fastestgrowing commercial cities in the world. The fast growth of theeconomy during the last five years, made UAE to experiencea rapid boom in the construction industry. The UAE leadersare now seeking a sustainable development for the countryby 2015. Therefore, developers in the UAE are to commenceexploring sustainable development and green buildingconcepts in order to maximize both economical, social andenvironment friendly performance of their buildings.Sustainable development is a pattern of resources use aimingto meet human needs while preserving the environment.Green building concept represents designing of any structure,built, renovated, in operation or re-used with objectives to:• Protect occupant’s health• Improve employee productivity• Use wisely natural resources• Reduce the environmental impactIt has now become a legislative requirement for buildingowners and developers to take into consideration the impactof the buildings towards the environment.More than 70 definitions of sustainable development aregiven and are used by different groups to suit their goals(Langston, Ding, 2004). A widely quoted definition ofsustainable development is the definition given in Brundtlandreport:“development that meets the needs of the presentwithout compromising the ability of future generations tomeet their own needs” (cited in Brundtland etal, 1997, p169)Seven green building rating systems are available to choosefrom and they are used for promoting and contributing toenvironmentally conscious construction practices.LEED is a certification scheme that produces independent thirdparty verification that a building project is environmentallyresponsible, profitable and a healthy place to live and work(USGBC). Initially LEED was designed for US buildings andfounder of the LEED rating system was Mr. David Gottfried.He formed the US Green Building Council in 1993. Now itis one of the fastest growing nonprofit organizations in theworld having over 20,000 member organizations. In 1998 heformed the Global Green Building Council (GGBC) comprisingwith fifty other countries including the UAE as well.However, (GGBC/ USGBC) does not have any provision toallow individual participants to be members. Organizations,regardless of their product, can be members, of the GGBC orUSGBC as appropriate.Sustainable development is a pattern ofresources use aiming to meet human needswhile preserving the environmentLEED is a voluntary certification system utilized to gain amarket share and advantage over competitors. This systemis based on a process in which certain building criteria isanalyzed, a credit value is designated, and a certificationstandard is conferred accordingly. Some of these main criteriaare:i] Site selectionii] Water efficiencyiii] Energy uses,iv] Atmospheric effectsv] Material and resources use,vi] Indoor environmental qualityvii] Innovation and design process of a buildingThese buildings must pass the LEED technical review toachieve certification and then these projects are certifiedby the USGBC. Points are awarded in various categories, asenergy use, water efficiency, and indoor environment quality.The total number of points received determines the building’sLEED rating. Also extra points can be earned by installingspecial features such as renewable energy generators orcarbon dioxide monitoring systems.20
SLQS JOURNALJanuary 2009Leed Rating SystemLEED Rating Systems are developed through an open,consensus based process according to the USGBC, a buildingthat achieve a score of;26 – 32 points earns a “Certified Rating33 – 38 points earns a “Silver Rating”39 – 51 points earns a “Gold Rating”52 – 69 points earns a “Platinum Rating”.Gold rated buildings are estimated to have reduced itsenvironmental impact by 50% compared with an equivalentconventional building, and a platinum rated building by over70%. (“Leadership in Energy & Environmental Design” NTRES431: Environment Strategies Fall 2004).As of June – 2008 the number of projects registers are 139,out of which 46 are registered by TECOM alone (USGBC,2008). However, the UAE construction industry steppedinto this concept and still is at a very primary stage. AbuDhabi’s Urban Planning Council, UPC will introduce a set ofregulations to suit the environment, climatic conditions andthe culture of the UAE. As per the UPC General Manager FalahAL Ahbabi’s views expressed in Construction Week September2008 issue, new “Pearl Rating System” will be affected fromJanuary 2009. Pearl Rating System includes rating from oneto five, and five is the highest category.The Pearl Rating System is known asESTIDAMA, which means “sustainability” in Arabic, is anintegrated program to devise guidelines and registrations forsustainable design, operation and maintenance of all typesof buildings and communities within Emirates of Adu Dhabi.Unlike other rating systems, ESTIDAMA can only be used toassess the sustainability performance of a buildings.Assessment and scoring aspects for Green Building designare:• Water 30%• Energy use 20%• Indoor environmental quality 15%• Ecology 7.5%• Management 5%• Transport 5%• Pollution 5%• Materials 5%• Waste Management 2.5%ESTIDAMA Pearl Rating scale is as follows:• 35%1 Pearl certificate• 45%2 Pearl certificate• 55%3 Pearl certificate• 65%4 Pearl certificate• 75%5 Pearl certificateHigh-performance green building is the solution to energyefficient buildings and conservation of water. It provideshealthy indoor environment and improves the productivity ofoccupants. (EGBC 2008, http;//www.emiratesgbs.org)The implementation of ESTIDAMA in the UAE can transformUAE into a green paradise of the desert.Independiente Ltd and others -v- Music Trading On-Line (Hk) Ltd and others (2003)The claimants claimed damages for the sale by the defendants in the UK of CD’s manufactured for sale only in the far East. Thedefendants challenged the right of a claimant phonographic society to have the right to sue on behalf of its members.Held: The right to issue representative actions varies with the nature of the claim. Did members of the society have a commoninterest in preventing parallel imports as opposed to preventing copyright piracy? Yes. The claims were all of the same nature andit was to be expected that the members would have a complaint. It was not necessary to require the claimants to circularise theirmembers to obtain specific authority under CPR 19.6(2).21
