Abu Dhabi Mosque Development RegulationsAppendix 1 - EstidamaI. Introduction to Estidama‘Estidama’, which means sustainability in Arabic, is theinitiative which will transform Abu Dhabi into a modelof sustainable urbanisation. Its aim is to create moresustainable communities, cities and global enterprisesby balancing the 4 pillars of Estidama: environmental,economic, cultural and social.The aspirations of Estidama are incorporated intoUrban Planning Vision 2030 and other Abu DhabiUrban Planning Council (UPC) policies such as theDevelopment Code. Estidama began in 2008 and isthe first programme of its kind that is tailored to theMiddle East region.environmentalIn the immediate term, Estidama is focused on therapidly changing built environment. It is in this areathat the UPC is making significant strides to influenceprojects under design, development and constructionwithin the Emirate of Abu Dhabi.The Pearl Rating System for Estidama (PRS) is 1 ofthe key tools for driving and determining sustainabledevelopment. The Pearl Rating System for Communities,Buildings and Villas provide a suite of tools that formthe basis for sustainable development from master planto finished building.estidamaeconomicThe Pearl Rating System for EstidamaThe PRS aims to address the sustainability of a givendevelopment throughout its life cycle from design andconstruction through to operation. The PRS providesdetailed requirements for rating a building’s potentialperformance in relation to the 4 pillars of Estidama.The PRS is organised into 7 categories that arefundamental to more sustainable development.Integrated Development Process: Encouragingcross-disciplinary teamwork to deliverenvironmental and quality management.Natural Systems: Conserving, preserving andrestoring critical natural environments andhabitats.Liveable Spaces: Ensuring the quality ofoutdoor and indoor spaces.Precious Water: Reducing water demand andencouraging alternative water sources.Resourceful Energy: Targeting energyconservation through passive designmeasures, energy efficiency and renewablesources.Stewarding Materials: Ensuring considerationof the ‘whole-of-life’ cycle when specifyingand disposing of materials.socialculturalInnovating Practice: Encouraging innovationand cultural expression in building design andconstruction to facilitate market and industrytransformation.Estidama - Page 1

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaEstidama for MosquesAll new mosques in Abu Dhabi Emirate are requiredto achieve a minimum 2 Pearl Rating under the PearlBuilding Rating System (PBRS). This means thatdevelopment teams will have to meet the requirementsof all applicable ‘required Credits’ in the PBRS as wellas a range of ‘optional Credits’ to earn a minimum of60 Credit Points.Mosque development teams are offered a wide range ofoptional Credits that may be targeted for their projectsto earn a minimum of 60 Credit Points. An extensiveconsultation has been undertaken between manystakeholders to identify a list of recommended optionalCredits for mosques which takes into considerationreligious requirements and local market capabilities.Mosque development teams are recommended to targetthese Credits before exploring other alternatives. Therecommended optional Credits are highlighted in theMosque PBRS Scorecard presented on the followingpage.Although a minimum 2 Pearl Rating is mandated for allmosque projects, mosque development teams may alsovoluntarily seek a higher rating of 3 to 5 Pearls. TheCredit Points required for each level are listed in Table 1.Table 1: Pearl Building Rating LevelsRequirementAll mandatory CreditsAll mandatory Credits + 60 Credit PointsAll mandatory Credits + 85 Credit PointsAll mandatory Credits + 115 Credit PointsAll mandatory Credits + 140 Credit PointsPearl RatingAchieved1 Pearl2 Pearls3 Pearls4 Pearls5 PearlsThe purpose of this document is to provide guidancefor the mosque development teams by presenting themost suitable pathway of ‘recommended optionalCredits’, in order to achieve a minimum 2 Pearl Rating.The detailed requirements of both the required andoptional Credits are available from the Pearl BuildingRating System (PBRS), available for download at www.estidama.org.The detailed calculation and documentationrequirements to demonstrate compliance with therequired Credit Points can be found in the PBRS.Members of a mosque project team must consult thePBRS for detailed submission requirements.Emirati Vernacular MosquesThe Abu Dhabi Mosque Development Regulationspromote the use of Emirati vernacular for the designof mosques. This approach is also in line withEstidama objectives, as there are several elementsof vernacular style, as outlined below, which help adesigner to achieve the recommended PBRS Credits.• Riwaq: By providing a shaded external space forprayer this will help to achieve Credit LBo-R3:Outdoor Thermal Comfort Strategy/LBo-1: ImprovedOutdoor Thermal Comfort.• Wind cooling: The cooling effect of the wind hasbeen used throughout Emirati mosque vernaculardesign to cool both the internal and external areas ofa mosque (e.g. sahan). This helps to achieve CreditsLBo-R3: Outdoor Thermal Comfort Strategy, LBo-1:Improved Outdoor Thermal Comfort and RE-R1:Minimum Energy Performance.• Prayer hall proportions: The simple prayer hallproportions used within Emirati vernacular designallow the creation of thermal zoning withinmosques, which helps to achieve Credit LBi-5.1:Thermal Comfort & Controls: Thermal Zoning.• Simple and modest building design: Throughthe use of Emirati vernacular design elements,the mosque achieves a reduced energy loading,helping to achieve Credit RE-R1: Minimum EnergyPerformance.• Use of simple regional materials: Traditional Emiratiarchitecture may use simple regional materials. Iffollowed, this may help to achieve Credit SM-9:Regional Materials.Estidama - Page 2

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaIII. How to Use the GuidelinesThese 2 Pearl Mosque Guidelines are intended tocomplement the PBRS, which is the primary referencedocument for Estidama compliance. This documentprovides design and development teams with guidancefor achieving the required and recommended Credits.Where relevant, these guidelines provide a prescriptivepath to achieving the required mandatory requirementsand Credits. Key features of the document organisationare highlighted below.This guideline forms part of the Abu Dhabi MosqueDevelopment Regulations (ADMDR). The ADMDR ismade up of 3 volumes and 3 appendices that regulatespecific aspects of the planning and design of amosque building, its surroundings and life cycle. Thefull list of documents is as follows:• User Guide• Volume 1 - Planning• Volume 2 - Design• Volume 3 - Operations• Appendix 1 - Estidama• Appendix 2 - Architectural Prototypes• Appendix 3 - Vernacular StudyThe ADMDR documents have been written tocomplement each other. The mosque developer,designer and contractor must utilise these guidelinesin conjunction with the entire suite of ADMDR volumesand appendices.The members of the design and development teamresponsible for requirements discussed on the page arehighlighted on the upper corner of the page.E - EngineerC - ContractorA - ArchitectO – Owner (Donor/Awqaf)CA - Commissioning AgentOS - Other SpecialistAbu Dhabi Mosque Development RegulationsVolume 5 - Estidama Guidelines1.0 Organise team + work 1.1 Assemble integrated development teamBefore beginning the design and development process, the project team should be organised in a way that integrates the contribution of differenttrades and specialities. This coordination, called an Integrated Development Process (IDP) in the Pearl Rating System, is simply a framework to supportthe development of holistic, creative, and efficient design solutions. The Pearls Rating System requires an IDP to extend throughout the project lifecycle from inception to design, construction and commissioning.ApproachAn IDP can be the foundation of a successful mosquedesign and development team, bringing out the bestinput of each member. In particular, once the designteam has been assembled, it facilitates the designprocess by:• Communicate to the mosque design team thesustainability objectives and obligations using theEstidama Pearl Rating System. By communicatingthis early the project team can aim to achieveambitious goals more efficiently and avoid anyincidental slippage in project performance.• Enabling true Collaboration and Continuity within thedesign and development team. By discussing projectgoals early on and meeting face-to-face as a singlegroup, the project team will be able to coordinatework smoothly and make decisions more rapidly.• Promoting System Thinking when developingstrategies and solutions. By considering theinterconnections between each discipline, the projectteam can deliver a high performing building morecreatively, and without expensive technological “addons.”ProcessAs the project team organizes its schedule, an IDPframework should be incorporated into the developmentprocess. This framework can be broken down into foursteps, which are detailed on the following pages.1 2 3 4assembleintegrateddevelopmentteamestablishinitialsustainabiltyvision andtargetsallow for regularcommunicationbetween thedifferent projectteam disciplinesSystem Thinkingmonitorregularly theprogress inmeeting visionand targetsThe Integrated Development Process (IDP) aimsto foster creativity and coordination in theproject design and development. Therefore, anIDP should involve all members of project team,especially the client/owner or financial decisionmaker.A mosque project team in its simplest form will becomprised of an Owner, an Architect, an Engineer and aContractor. Typically the contractor will be responsiblefor all subcontractors. Specialists may also be broughtonboard to undertake specialized work in areas such assustainability, landscape architecture, interior design orenvironmental services.The project team should consider several points as itorganizes its work:Each member of the team should become familiarwith Estidama and the Two-Pearl requirementsunder these guidelines and the Building RatingSystem. This is available on the Estidama website(www.estidama.org).The IDP process should be coordinated by a memberof the design team who has been certified as aPearl Building Rating System Professional. It isnot necessary that this person be a dedicatedsustainability consultant. They could be anymember of the design team who has receivedthe building certification. More information aboutthis certification is available about this at www.estidama.org.Every member of the project team should contributeto the design. In order to develop more integrativeideas, team members should consider themselvescollaborators in the design, even before the Architecteven puts pen to paper. Although the contractor istypically involved later in the process, they should beinvolved as early as possible.123ENGINEERCONTRACTORARCHITECTOWNER (Donor/Awqaf)COMMISSIONING AGENTOTHER SPECIALISTExample 1.1astructural designefficient designsbuilding systemsmodellinglocationvisiontargetsbudgetoperationsExample 1.1b: Team structureBuilding DesignLandscape DesignStructural EngineeringSkillsMEP EngineeringConstructionOperations &MaintenanceAbu Dhabi Mosque Development RegulationsVolume 5 - Estidama Guidelinesbuilding operationsmaintenance requirementsCommissioningAgentvisionpassive designsEngineerArchitect layoutecologyOwner ContractorsuppliersPearlcostQualifiedProfessionalconstructabilitycoordinationsystem thinkingperformance assessmentinnovationRolePearlOwner Architect Contractor EngineerComissioning QualifiedAgent ProfessionalX X XXX XXXXX X XX X XX X X X XChapter Page 28Chapter Page 29Figure 2: Extract from Appendix 1 - Estidama.Estidama - Page 4

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama1.2 Initial Vision and TargetsThe most important aspect of the IDP is a shared visionand a series of targets established to achieve it. Theseshould be developed early in the design process andbe aligned with the minimum 2 Pearl requirements formosque design.1Develop a vision for the mosque project. Thisshould be a general aspirational target that willgive coherence to the design process.2Establish objectives for achieving the vision.These should be more specific goals.3Establish specific and measurable targets forachieving the objectives and vision. These willform a framework for the design process.4Develop solutions for reaching the targets.Identifying practical, cost effective, integratedsolutions will be the outcome of the design anddevelopment process.VisionObjectivesTargets (Credits)SolutionsFigure 6: Narrative summarising vision,objectives and targets.“Provide a comfortable environment for worshipthat will avoid wasteful resource use.““Adopt a climate-responsive design thatminimises the need for artificial lighting and airconditioning,and uses efficient technologies thatreduce energy and water consumption.““Reduce potable water use to 20% belowthe usage of a typical mosque” (Credit PW-1Improved Interior Water Use Reduction); “Designthe mosque to achieve a minimum energyperformance as per Credit RE-R1: Minimum“Architect: Strategic window placement andshading.

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama1.3 Design WorkshopsAfter a kick-off workshop and establishment ofthe vision, objectives and targets, it is important tocontinue holding multidisciplinary design workshopsto foster creativity and collaboration and to ensureeveryone is aware of important decisions madethroughout the development process.Schedule regular multidisciplinary workshops at theoutset of project planning. These should include thefollowing topics, at a minimum:• site and ecology;• orientation and climatic response;• energy and water consumption;• waste management;• indoor comfort; and• sustainable materials specifications.Additional workshops can also be scheduled on an ‘asneeded’ basis. Each meeting should be documentedin an appropriate manner. This could take the form ofphotographs or signatures of design members presentat workshops. • • • • • Figure 8: Workshop documentation.Month 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24Organise team and workUnderstand plot contextPlan plot layoutDesign outdoor spaceDesign indoor spaceDesign building servicesApply for building permit applicationDesign rating submissionBuild mosqueApply for building completion certificateFigure 7: Mosque Integrated Development Process chart.Related Credits:IDP-R1: Integrated Development Strategy.Pre-planning Design Construction SubmissionsEstidama - Page 8

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama1.4 Implementation StrategyA strategy for implementing the sustainability goalsof a mosque should be developed to ensure thatsustainability targets established during design aremet during construction and occupancy. This can befacilitated as the team is organised.All members of the development team should beengaged early in the process, including the contractorand commissioning agent (who will verify theperformance of building systems). If possible, thesemembers should be involved in the whole IDP process.The specification documents must contain thesustainability targets and solutions established duringthe IDP workshops. There should be language ensuringcompliance with all mandatory PBRS Credits andtargeted optional Credits that lead to a 2 Pearl Rating.The mosque Imam must receive an OperationsManual and a Maintenance Manual. These willprovide instructions on efficient operation and propermaintenance of building systems, as well as behavioursthat reduce the waste of resources.

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama2.0 Site ContextAt the start of the design process, the design teamshould seek ways to understand and optimisethe relationship between the mosque plot and itssurroundings.A thorough understanding of the site’s natural andurban context will help inform an optimal plot layoutand mosque design. This will support many designobjectives, including:• improved outdoor thermal comfort;• energy use reduction;• water conservation; and• ecological enhancement.There are many resources that can support an analysisof both natural and urban systems, including themaster planning documents for the neighbourhoodin which the mosque is located. Others are listed in‘Useful Resources’ below.Natural systems, such as the existing habitat andtopography, and urban systems, such as nearbycommunity facilities, could be examined in separateassessments or together. Ultimately, all site informationshould be integrated in order to identify opportunitiesand constraints associated with building on a particularplot.STEP 1Assess, Protect and Manage NaturalSystems+Assess Urban Systems+Understand Relevant Plan 2030Regulatory FrameworkRelated Credits:NS-R1: Natural Systems Assessment.LBo-R2: Urban Systems Assessment.Identifying important contextual opportunities andconstraints allows the mosque development to takeadvantage of special site features and address sitechallenges effectively. Information obtained in theNatural and Urban Systems Assessment informs theformation of a complete opportunities and constraintsanalysis. An example study is shown on page 12,illustrating how opportunities and constraints can beused to inform the design of a plot.The design team should then move onto the next stepin the process; planning the plot layout.Useful Resources:• UPC Plant Information Database www.upc.gov.ae• Geographical Information Database for UAEhttp://geoportal.abudhabi.ae• Google Map/Earth• EnergyPlus Weather Datahttp:// apps1.eere.energy.gov• Interpretation Manual of Major Terrestrial Natural andSeminatural Habitat Types of Abu Dhabi Emirate, GaryBrown and Benno Boer, Environmental Research andWildlife Development Agency, September 2004.• Terrestrial Environment of Abu Dhabi Emirate,Environment Agency Abu Dhabi, 2008www.ead.aeSTEP 2IdentifyOpportunitiesand Constraints• Handbook for Phase 1 Habitat Survey – a techniquefor environmental audit, JNCC, 2007www.jncc.gov.uk• Environment Agency http://www.ead.ae• Union for Conservation of Nature, IUCN,www.iucn.org• Wild Flowering Plants of UAE, Environmental Researchand Wildlife Development Agency, 2002• Birds of Abu Dhabi - Checklist, EnvironmentalResearch and Wildlife Development Agency, July2001• Vascular Plants of Abu Dhabi Emirate, Gary Brown andSabitha Sakkir, August 2004Regulation and Supervision Bureau (RSB)www.rsb.gov.ae• Abu Dhabi Water and Electricity Authority (ADWEA)www.adwea.com/en/index.htmlAbu Dhabi Water and Electricity Company (ADWEC)www.adwec.ae• Abu Dhabi Distribution Company (ADDC)www.addc.ae• Al Ain Distribution Company (AADC) www.aadc.ae• Abu Dhabi National Energy Company (TAQA)www.taqa.ae/en/uae.html• Abu Dhabi Transmission and Dispatch Company(TRANSCO) www.transco.aeSTEP 3Design OutdoorSpacesEstidama - Page 10

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaExample - Natural and Urban Systems Assessment• Although sparsely vegetated, the proposed plotincludes 2 notable ecological assets, depicted inphotos (a spiny-tailed lizard burrow and several ghaftrees). The existing ghaf trees, as a native species,are valuable for both habitat and landscaping.• The plot is mostly flat with soil being found to besandy up to a depth of 35cm with a more rockysubstrate underneath. In the north western portionof the plot area, soil contains more sandy load,which is in part related to the presence of trees.• As a previously unutilised location, no contaminationhas been identified or suspected on this plot.• Within a 350m walking distance there are mostlyresidential zones with 2 community facilities: aschool and a community centre.• The area is only served by 1 bus route connectingthe neighbourhood to Abu Dhabi City. Parking isavailable running parallel to the E11 Highway.• The main line utilities run along the major E11Highway with the authorities providing utilitiesaccess from the neighbouring community.• The existing streets throughout the communityare dual single lane streets which also include apedestrian corridor on both sides.• The microclimate generally corresponds to Abu Dhabiaverages with some particularities as follows:• high midday sun with marginal overshadowingfrom adjacent developments to the south;• exposed on north and south sides;• warmer southern winds prevailing during the day;• existing trees on the plot provide shaded zones;and• adjacent properties can break-up wind patternsand introduce turbulence.Spiny-tailed lizard burrow.Dominant WindCommunity facilitieswalking distance (350m)Bus stopUtilities corridorsExisting ghaf treesCommunity facilities(1-school /2-community centre)Mosque Plot1Ghaf trees.2Sun PathFigure 10: Natural and urban systems assessment plan.Estidama - Page 12

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama2.2 Natural Systems ProtectionAfter evaluating the natural assets of the plot, thedesign teams must build around or responsibly relocateexisting natural assets and offset any disruption causedby development.Where Significant and Valuable Assets are present, aNatural Systems Protection, Mitigation or CompensationPlan needs to be produced. This, along with supportingstudies, must be prepared by a suitably qualifiedecological specialist.The ecological features of the plot can either beprotected or disturbance can be mitigated. 3 strategiesto do this are identified in the PBRS. These aresummarised in Table 2.Table 2: Natural Systems Protection, Mitigation or Compensation PlanStrategySignificant assets to beprotected on-site (%of significant assets)Valuable assets to beprotected on-site (%of valuable assets)Maximum reclaimedland (% of land area)Max impact affectingthe coastal edge (% ofcoastal edge)If the Natural Systems Assessment clearly documentsthat the plot has no significant or valuable naturalassets, the plot does not need protection or mitigation.A further Credit can be achieved if the requirementsof Credit PW-2.1: Exterior Water Use Reduction:Landscaping are followed and the project provideslandscaping that consists of native species and usesminimal water.All Significant Assets associated with a protected area,national park, a coastal park, ecological hotspot, or acoastal conservation zone, must be protected, and 80%of Valuable Assets protected.Mitigate/compensatelost habitat at an areareplacement ratio of:Other Requirement/CommentIf part of the Natural Systems Design and ManagementStrategy includes mitigation or compensation, atleast 70% of Significant Assets and 50% of ValuableAssets must be protected. If mitigation occurs onsite,new habitat areas must equal the area of the lostassets. If on-site mitigation is impractical and off-sitecompensation must be pursued, the new habitat areamust be twice the area of assets lost.During the design of outdoor areas, project teamsshould lay out buildings, streets and public spaces onsiteto protect and celebrate the presence of on-siteecological features. These features could form a themefor site-wide landscaping strategies.The Natural Systems Design and Management Strategyshould outline any activities that may cause damage tosensitive areas during the construction and operationphases of the development. It should identify measuresthat have been designed into the scheme and those thatwill be implemented during operation to protect theseareas/species, for example; limiting access to mangroveareas and providing boardwalks for pedestrians tominimise damage to mangrove roots. The Strategyshould include measures such as:1. Protection 100% 80% 25% 20% N/A2. On-siteMitigation(UPC approvalrequired)3. Off-siteCompensation(UPC approvalrequired)70% 50% 25% 20% 2:170% 50% 25% 20% 2:1Retain and protect from damage and destructionsufficient to maintain the feature’s existingstructure and function.Provide an ecological corridor between plot andmitigated area.Confirmation of the appointment of amanagement and maintenance contractor(minimum 5 year contract).Compensation site in Emirate of Abu Dhabi, adegraded area and located outside Plan 2030area.Confirmation of the appointment of amanagement and maintenance contractor(minimum 5 year contract).• design protection measures;• ensuring that work compounds, access tracks and soon are not located in or adjacent to sensitive habitats;• establishing temporary fencing around protected areasto restrict access;• undertaking any works near protected areas in amanner so as to safeguard their integrity; and• undertaking works considering any critical seasons forprotected species.Estidama - Page 13

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaSome of these measures could be included in theConstruction Environmental Management Plan(CEMP) when prepared as part of the requirementsof Credit IDP-3: Construction EnvironmentalManagement.As well as the Natural Systems Assessment Report,the Mitigation Strategy Report should identify theareas to be protected and measures adopted toensure their protection, as outlined in the ProtectionStrategy Report. It should identify the mitigationareas and justification for the appropriateness formitigation including:• area calculations;• identification of appropriate plant nurseries;• continuous monitoring of success or failure ofyoung plants; and• management techniques to encourageestablishment, which should be adapted followingany failures (if any).The Compensation Strategy Report shoulddemonstrate options considered for off-sitecompensation and the selection criteria for theproposed compensation site. The Report shouldinclude measures to ensure flora establishmentas outlined in the Mitigation Strategy Report andprotection measures as outlined in the ProtectionStrategy Report. Consideration should be givento the habitat lost on the proposed plot and thepotential to provide enhanced habitat of a similartype to the habitat lost. The author of this chapterof the Natural Systems Assessment Report should bea qualified ecologist who has experience in habitatestablishment for those particular habitats, e.g. amangrove specialist.Related Credits:NS-R2: Natural Systems Protection.IDP-3: Construction Environmental Management.PW-2.1: Exterior Water Use Reduction: Landscaping.Estidama - Page 14

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama3.0 Design of Outdoor SpacesFollowing on from the natural and urban systemsassessment and analysis work to determine thebroader natural and urban context of the mosqueproject (refer to Section 2.0), the design anddevelopment team must address the followingdesign factors when planning the layout of outdoorspaces within the mosque plot in order to develop anintegrated approach to plot planning and design:• accessibility and connectivity;• ecological enhancement;• outdoor thermal comfort;• water efficiency;• energy efficiency;• waste management;• hazardous materials; and• smoking control.Careful consideration must be given when locatingbuildings within the plot, pathways and plot accesspoints to optimise accessibility and connectivity withthe surrounding community amenities and facilities inaccordance with Credit LBo-3: Accessible CommunityFacilities and Volume 1 - Planning (refer to Section3.3). The mosque should also be linked to adjacentstreets to facilitate pedestrian, bicycle and vehicularmovements and provide adequate bicycle storageto meet the requirements of Credit LBo-7: BicycleFacilities.The mosque plot landscape should be designed torespect and link to existing natural habitats, wherepresent, and should have a clear and coherent NaturalSystems Design and Management Strategy as requiredby Credits NS-R2: Natural Systems Protection and NS-R3: Natural Systems Design and Management Strategy.The extent, selection, location and irrigation strategyof the mosque’s plant palette should result in reducedirrigation demand as required by Credit PW-2.1:Exterior Water Use Reduction: Landscaping, whileproviding sufficient planting to meet design objectives.Appropriate building massing, the integration of wellplacedand well-chosen landscaping, both soft andhardscapes and sufficient and appropriate shadingelements, such as trees and/or structural shading,will contribute to improving outdoor thermal comfortto address the minimum requirements of CreditsLBo-R3: Outdoor Thermal Comfort Strategy and LBo-1:Improved Outdoor Thermal Comfort.Although the orientation of the mosque is fixedtowards qibla, the placement of mosque buildingswithin the plot and in relation to each other, coupledwith a climate-responsive envelope design, providegood opportunities for reducing energy demandin relation to Credit RE-R1: Minimum EnergyPerformance. Design and development teams shouldexplore opportunities to reduce internal heat gainswhile harnessing sufficient daylight in key spaces suchas prayer halls.While the amount of glazing should be limited to whatis necessary, achievement of this is demonstrated by:• careful placement of glazing within the buildingenvelope;• integration of shading, such as mashrabiya panels oroverhangs, to limit or eliminate direct solar radiation;and• use of envelope components (such as windows, wallsand roofs) that meet the maximum performancecriteria specified in Credit RE-R1: Minimum EnergyPerformance.The mosque must include appropriately sized externalwaste storage spaces with appropriate and adequateaccess for waste collection vehicles to meet therequirements of Credit SM-R3: Basic Operational WasteManagement.Hazardous materials in outdoor spaces, such as treatedtimber containing Chromated Copper Arsenate (CCA),must be avoided as per the requirements of Credit SM-R1: Hazardous Materials Elimination. Outdoor items,such as shading structures and outdoor furniture, mustbe evaluated where they are proposed. It is unlikelythat playground furniture will be present, but if it isintended, then this must also be considered.Finally, a mosque plot-wide smoking ban must beintroduced to meet the requirements of Credit LBi-R2:Smoking Control. In particular, signage should beprovided at key locations to indicate that visitors areentering a non-smoking environment.Related Credits:NS-R2: Natural Systems Protection.NS-R3: Natural Systems Design and Management Strategy.LBo-R3: Outdoor Thermal Comfort Strategy.LBo-1: Improved Thermal Comfort.LBo-3: Accessible Community Facilities.LBo-7: Bicycle Facilities.LBi-R2: Smoking Control.PW-2.1: Exterior Water Use Reduction: Landscaping.RE-R1: Minimum Energy Performance.SM-R1 Hazardous Materials Elimination.SM-R3: Basic Operational Waste Management.Estidama - Page 15

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama3.1 Plot LayoutThe layout of the mosque within the designated plothas many implications later in the design process,especially with regards to energy performance andoutdoor thermal comfort. In addition to the guidanceprovided in Volume 2 - Design, the design team shouldcarefully consider the following:Optimise Natural Light but Minimise Solar Gains1234Utilise external shading devices to reducesolar gain, while maintaining external views(e.g. provision of horizontal shading on southorientation and vertical shading on east and westorientations).Use shadows cast by surrounding buildings toprovide shade and reduce solar gain.Locate windows in shaded areas, recessed intothe wall, or facing north to provide light to indoorspaces.Use roof-lights sparingly as these significantlyincrease solar heat gains. Consider using sunpipesor solar-tubes instead.Harmonious Integration with Surroundings andPedestrian Environments1234Cool breezes can reduce heat build-up in externalareas as well as freshen the air in externallyaccessible areas. Hot winds cause unpleasant anduncomfortable conditions resulting in the buildup of heat in external areas, which increases theheat load of the building and pedestrian thermaldiscomfort.Consider position, form and orientation of nearbybuildings to understand wind movement and howthe external environment is affected.Use mosque form and position to best use coolbreezes. This will help to reduce the build-up ofheat and/or stagnant air at pedestrian level.Use the mosque form to shelter pedestrian areasfrom hot or high-speed winds. Consider the useof external mosque features, as well as mosqueform and massing, to minimise adverse impactsof the wind on the public realm. Features to beconsidered include, but are not limited to:56Consider potential adverse impacts of downwash,corner accelerations and local wind directionchanges amongst other effects.Consider the need for mitigation of adverse windconditions within the public realm. Potentialmitigation strategies include, but are not limitedto:• canopies;• wind screens;• shelter belts; and• deployable structures.• shading devices, e.g. brise-soleil, mashrabiyapanels, etc;• overhangs;• breaks in façade continuity;• podiums;• openings; and• permeable features.Related Credits:LBo-R3: Outdoor Thermal Comfort Strategy.RE-R1: Minimum Energy Performance.Estidama - Page 16

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama3.2 Outdoor Thermal ComfortOutdoor thermal comfort is especially important for amosque given the potential for worshipper overflowduring Friday, Ramadan or Eid prayers, thereforeprovision of shading to provide outdoor thermalcomfort is required for specific outdoor areas of themosque.To achieve worshipper comfort, it is required that theshading percentage required in Credit LBo-R3: OutdoorThermal Comfort Strategy is achieved on the summersolstice (June 21st at 1.00pm) within the followingmosque areas:• overflow prayer areas; and• pedestrian walkways.Mosque building orientation can maximiseopportunities for solar heat gain avoidance duringsummer months and self-shading throughout the year.The basic consideration for optimising self-shadingopportunities includes the directional orientation of thesupporting mosque building (excluding the predefinedprayer hall orientation), which would facilitateachieving the shading requirements of Credit LBo-R3:Outdoor Thermal Comfort Strategy.Additional shading can be provided by mature trees orby structures such as canopies. If structural elementsare used, their outer surfaces must have a minimumSolar Reflectance Index (SRI) of 29. The SRI is ameasure of a surface’s ability to reflect solar heat ona scale of 0 to 100. The higher the SRI value is, thebetter the surface is at reflecting solar heat.High SRI values can be achieved through the useof light reflective materials or finishes. Despitethe importance of shading outdoor areas, carefulconsideration is required in the design of shadingfeatures so as not to detract from the aesthetics of themosque and to avoid obstruction of major walkwaysleading worshippers to and from the mosque.The following requirements in Table 3 illustratepotential strategies for acquiring the necessary shadingpercentages using optimised mosque layouts, naturalelements or selective construction elements.By complying with these requirements, the mosque iseligible for 1 Credit Point under Credit LBo-1: ImprovedOutdoor Thermal Comfort. A shading calculator,available from the Estidama website or alternatively,propriety software, can be used to demonstratecompliance with this Credit.Table 3: Required Shading LevelsLocation Shading Requirement Time of ShadingRiwaq 100%Summer Solstice(June 21st) at1.00pmSahanPublicCirculationAreasNo PBRS requirement(but shading must beprovided if overflowis expected within theproject).85% (this should include,at a minimum, a linkbetween a plot entryportal and the riwaq andother high pedestriantraffic use areas).Summer Solstice(June 21st) at1.00pmSummer Solstice(June 21st) at1.00pmNote: All prayer areas, including overflow prayer areas shall provide 100%shading.

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama3.3 Accessibility and Provision of Community FacilitiesA mosque provides a location where the communitycomes together on a regular basis. Therefore, it isbeneficial that a mosque be accessible and located inan area with safe and easy access to other communityfacilities. This will allow worshippers to combine dailyprayers with day-to-day tasks and will promote theuse of individual mosques.Designing a mosque adjacent to community facilities(e.g. adjacent to a kindergarten or grocery store) ishighly encouraged as it will provide worshippers withadditional points of activity and social interaction,helping to integrate the mosque within the community.Locating mosques adjacent to existing or plannedwomen’s centres will encourage female worshippersto attend daily prayers in the designated prayer area atthe mosque. Moreover, incorporating crèches into themosque design provides the opportunity for familieswith dependent infants to attend daily prayers at themosques within their community.The provision of community centres and recreationareas adjacent to the mosque will encourage localyouth to attend daily prayers at the mosque as theywill be able to combine daily prayer with recreationalactivities.Related Credits:LBo-R2: Urban SystemsAssessment.LBo-3: Accessible Community Facilities.LB0-4: Active Urban Environments.LBo-7: Bicycle Facilities.A full list of eligible community facilities can be foundwithin Credit LBo-3: Accessible Community Facilitiesand are summarised as follows:• women’s centre or youth centre;• kindergarten, daycare or school;• library;• post office;• police station;• healthcare facilities/pharmacy;• public open space that contains shaded playgrounds,public squares and family parks; and• retail comprising any of the following:• bank and ATM;• grocery store or supermarket;• restaurant and cafe; and• general retail.The mosque will be eligible for 1 Credit Point underCredit LBo-3: Accessible Community Facilities whereit can be demonstrated that 5 of the above listedcommunity facilities are within a 350 m safe walkingdistance from the mosque plot boundary.The developer will need to submit a site plan indicatinga 350 metre radius around the mosque building andindicate on the plan where the community facilities arelocated within this radius.Bicycle FacilitiesAll mosques should provide bicycle storage facilitiesso that worshippers who wish to ride a bicycle to themosque can do so. The provision of bicycle storagefacilities will promote alternative transport and ahealthier lifestyle.The requirements of Credit LBo-7: Bicycle Facilities aresummarised as follows:• provide solid bicycle parking stands that allow bothbicycle wheel and frame to be securely locked;• ensure each bicycle stand is at least 2 m x 0.75 m;• ensure that an aisle of at least 1.5 m wide isprovided alongside the bicycle parking to allow formanoeuvring;• provide shading for all bicycle parking stands; and• to avoid congestion, bicycle storage facilities shouldbe located within the plot boundary at a suitabledistance from the mosque entrance, but still within asuitable walking distance from the mosque entrance.The mosque designer should provide a minimum of2 bicycle parking stands per 10 parking bays, but notless than that required by Volume 1 - Planning (refer toSection 2.0), highlighted below:• a minimum of 5 bicycle parking stands for mosquesdesigned to accommodate less than 500 worshippers;or• a minimum of 10 bicycle parking stands for mosquesdesigned to accommodate 500 worshippers or more.By complying with these requirements the mosque iseligible to achieve 1 Credit Point under Credit LBo-7:Bicycle Facilities.Estidama - Page 18

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama3.4 Safe, Secure and Healthy EnvironmentsSafety and SecurityProviding a safe and secure environment forworshippers to pray in is of high importance (refer toVolume 2 - Design). The key drivers behind safety andsecurity for mosques are as follows:• fire and life safety: Ensure that worshippers areprotected in the unlikely case of a fire within themosque.• crime protection: Ensure the risk and threat of crimein and around a mosque is eliminated through smartenvironmental design.• physical security: Ensure a safe, secure and accessibleenvironment is provided to worshippers.• community support: Ensure the mosque design allowsit to play a central role within the community.Examples of Physical Security and CommunityAccessMosque users require movement not only along thestreet in the pedestrian realm but also in areas wherepedestrian crossings are located. As pedestrians,mosque users are the most vulnerable of all streetusers. Special care and consideration is neededto identify potential issues and to design facilitiesaccordingly.Care should be taken when considering how themosque will be linked to the rest of the community.To provide a high-quality pedestrian environment andensure pedestrian safety, pedestrian crossings shallbe provided on all streets to accommodate primarypedestrian desire lines and should meet the spacingstandards outlined in the Abu Dhabi Urban StreetDesign Manual.Healthy EnvironmentCredit LBi-R2 Smoking Control has the followingrequirements for mosque projects:• establish smoke free environments in all internal andexternal areas within the mosque plot boundary;• train security staff to enforce a non-smoking policy;and• provide signage which indicates that all internal andexternal areas of the mosque are designated smokefree.The objectives and design guidelines of safety andsecurity for mosques are detailed within Volume2 - Design. The mosque designer should utilise thisguidance within the design of the mosque.By complying with these requirements and therequirements of Credit LBi-10: Safe & SecureEnvironment, the mosque is eligible to achieve 1 CreditPoint.BuildingMosqueTurnLaneZebraCrossingTurnLaneMedianStop LineCrosswalk is off-set in median sopedestrians will be oriented towardoncoming trafficBuildingOverhead mast armwith lighted pedestriansign or signalBuildingFigure 12: Safe access to the mosque.Related Credits:LBi-R2: Smoking Control.LBi-10: Safe & Secure Environment.Estidama - Page 19

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama3.5 External Waste and Recycling StorageThe mosque design and development team mustdevelop an Operational Waste Strategy as per therequirements of Credit SM-R3: Basic Operational WasteManagement. The strategy should address:• all sources of waste generated within the mosqueplot and throughout its operation;• the provision of adequately sized on-site storage;• accessibility of storage areas by waste collectionvehicles; and• final handling in terms of recycling or disposal.The strategy must result in the provision of anappropriately sized external waste storage area and anyrelevant indoor storage containers where waste can besegregated into the following streams - at a minimum:• recyclable plastics, glass and metals;• recyclable paper and cardboard; and• non-recyclable waste.In addition, a special container must be provided forthe collection of Islamic documents which require aspecific handling procedure by Awqaf and the AbuDhabi Center of Waste Management.Waste Storage SizingThe sources of waste within a mosque will varydepending on the mosque size, the extent oflandscaping, specific operations (e.g. paper towelsprovided in ablution areas/plastic cups provided atdrinking points), the time of week or year (i.e. regularprayer time vs. Ramadan, where Iftar meals may beoffered), and the mosque’s relation to the communitywhere it is located (i.e. whether the mosque wasterecycling points will be used by worshippers to disposeof collected recyclable household waste). The designand development team must identify all possible wastestreams throughout the mosque operation in orderto provide adequate external waste and recyclablesstorage. Further guidance may be obtained from theAbu Dhabi Center of Waste Management.Waste Storage Location and DesignThe mosque designer should consult with the localMunicipality and the Abu Dhabi Center of WasteManagement to identify the best location of theexternal waste storage area within or outside themosque plot boundary. The discussion should alsoaddress the following:• accessibility requirements for waste collectionvehicles (e.g. provision of a ramp);• labelling requirements;• security (e.g. locked waste room);• lighting provisions; and• cleaning requirements (e.g. use of ceramic finishesand provision of water and wastewater points).Related Credits:SM-R3: Basic Operational Waste Management.SM-14: Improved Operational Waste Management.Estidama - Page 20

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaSoil Protection and EnhancementPlant selection should suit existing soils on-site. Wheresoil enhancement is required, this should be tailoredto the existing soil type. Design and developmentteams should consider enhancing soils with waterand nutrient retaining supplements. Soils should beprotected from erosion, pollution and increases insalinity. Paths should be provided to avoid pedestriancompaction of soil. Irrigation should consider thetopography of the site and soil erosion.Ecological EnhancementThe mosque design and development team shouldconsider the use of a variety of native and adaptiveplant species within the plot boundary. 2 CreditPoints are available under Credit NS-3: EcologicalEnhancement when 70% of the plants used as part ofthe landscape comprise native, drought and/or salinetolerant species and a minimum of 10 plant species.Low Maintenance RequirementsLandscaping should be a combination of hard andsoft landscaping, and should minimise the applicationof fertilisers, pesticides and herbicides. Landscapingshould promote low maintenance requirements.Low Demand for ResourcesPlant selection should reflect the microclimateconditions of the area. Water efficient irrigationsystems, such as monitored drip irrigation, shouldbe adopted to minimise water consumption (refer toVolume 2 - Design).Related Credits:NS-R3: Natural Systems Design and Management Strategy.NS-3: Ecological Enhancement.Estidama - Page 22

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama3.7 Landscaping and IrrigationThe landscaping and irrigation of the external mosqueareas will have a wide range of impacts on thesustainability of the mosque. These impacts rangefrom irrigation water demand and material selectionthrough to plant selection and open space provision.It is important that the mosque designer understandsthe landscape and irrigation requirements andshould take into consideration any information takenfrom the Natural Systems Design and ManagementStrategy. The mosque designer should also workin close communication with the Awqaf-appointedmaintenance contractor who will be undertaking theoperation and maintenance of the landscaped areas.Hardscape Material SelectionThe mosque designer must implement the followingdesign measures when selecting hardscape materialsfor external landscape design:• meet the requirements of Volume 2 - Design;• materials selected must have high reflective/lightcoloured surfaces to avoid heat absorption. Allhardscape materials must have a Solar ReflectiveIndex (SRI) of 29 or greater. The SRI can be obtainedfrom the material manufacturer;• all hardscape materials must be interlocking orstandard pavers to allow for easy replacement ofhardscape; and• all hardscape materials must consist of permeablesystems or open pavers. Where appropriate, thedesigner must consider subsurface conditions toensure that it is capable of appropriate infiltration.Irrigation RatesThe average irrigation rate to be utilised for landscapedareas must be a maximum of 2 l/m 2 /day. This irrigationrate is to be applied to the whole of the landscapedarea. This means that the ratio of hardscape tosoftscape areas will determine the amount of irrigationwater available for softscape areas.For example, should a landscaped area consist of50% hardscape and 50% softscape then applying anirrigation demand rate of 2 l/m 2 /day across the entirelandscape will essentially allow 4 l/m 2 /day of irrigationdemand to the softscaped areas (there is no need toirrigate hardscape areas).By complying with the requirements of Credit PW-2.1: Exterior Water Use Reduction: Landscaping andproviding the Estidama Assessor with the relevantcalculations, the mosque is eligible to achieve 4 CreditPoints.Estidama - Page 23

Abu Dhabi Mosque Development RegulationsAppendix 01 - EstidamaIrrigation SystemsAll mosques within the Emirate of Abu Dhabi mustincorporate water efficient irrigation systems. Thismeans implementing strategies and technologies whichwill minimise the amount of potable water lost throughsystem losses (i.e. leakage) or operational losses (i.e.wind spray).The mosque designer can implement the followingdesign measures into the mosque irrigation system:• sub-surface drip irrigation system with appropriatefiltering to avoid clogging;• moisture sensors to minimise excessive irrigationlevels;• grouping all planting into irrigation zones with therequired demand rate dependent on plant demandrates; and/or• soil amendment techniques to promote healthy soilsand reduce evapotranspiration.The mosque designer must submit a narrativeexplaining the irrigation system design and includerelevant schematic diagrams and specification.By complying with the requirements of Credit PW-2.1:Exterior Water Use Reduction: Landscaping, the mosqueis eligible to achieve 1 Credit Point.Irrigation Operation and MaintenanceThe Awqaf-appointed maintenance contractor willbe responsible for the operation and maintenance ofthe irrigation systems for all mosques. The mosquedesigner must communicate the irrigation systemrequirements to the Awqaf-appointed maintenancecontractor and develop an appropriate IrrigationOperation and Maintenance Plan for inclusion in theOperations and Maintenance Manuals (refer to Volume3 - Operations).The Irrigation Operation and Maintenance Plan mustinclude, as a minimum, the following:• regular monitoring requirements of the water usageand efficiency of the irrigation system, includinglocating and fixing any leaks present;• the procedure to shut system down when a failureor leak occurs in the system to prevent wastage ofwater;• the philosophy for the collection, storage and reuse ofcondensate recovery water;• the control philosophy for irrigation zoning, and theability to shut individual irrigation zones down in theevent of a malfunction; and• details on the irrigation system metering and submeteringarrangements.Recycled Condensate WaterIn order to further minimise potable water use in themosque irrigation system, the mosque designer mustallow for the provision of an exterior water allowancefrom the condensate recovery from Air Handling Units(AHUs) and Fan Coil Units (FCU).The mosque will be designed to allow for the capture,storage and reuse of condensate recovery water intothe irrigation system. The mosque developer will needto determine the amount of water obtained throughcondensate recovery. Where the condensate recoveryis equal to the irrigation requirements the mosque willbe eligible for 2 Credit Points under Credit PW-2.2:Exterior Water Use Reduction: Heat Rejection.Note that if the mosque does not use water for heatrejection (i.e. it only uses FCU), then the mosque will,by default, achieve 8 Credit Points under PW-2.2:Exterior Water Use Reduction: Heat Rejection.Related Credits:PW-2.1: Exterior Water Use Reduction: Landscaping.PW-2.2: Exterior Water Use Reduction: Heat Rejection.SM-9: Regional Materials.SM-10: Recycled Materials.Estidama - Page 24

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama3.8 Stormwater ManagementDespite the low frequency of rainfall in Abu Dhabi,when storm events occur they often result in flashfloods, which results in traffic congestion and thepollution, and contamination of land, urban stormwaterdrainage systems and receiving water bodies in theEmirate.Credit PW-4: Stormwater Management encouragesmosque design and development teams to developstormwater management solutions that address bothstormwater quantity and quality control.Quantity ControlWhen designing roofs and ground landscaping of themosque, the designer must consider ways in whichto control stormwater run-off and quantities. This ispossible through the use of:• pervious hardscaping products that promoteinfiltration such as open-grid paving;• Sustainable Urban Drainage Systems (SUDS) such asponds, vegetated swales and wetland; and• structural stormwater management solutions such astanks, pipes and concrete channels.The mosque designer must demonstrate throughcalculations that the post-development stormwaterrun-off and quantities as a result of the 2 year(24 hour) design storm, does not exceed the predevelopmentrun-off and quantities. By complyingwith these requirements, the mosque is eligible toachieve 1 Credit Point under Credit PW-4: StormwaterManagement, when a combination of structural andnon-structural control solutions are used. Furtherguidance on stormwater calculation is provided.Quality Control:Stormwater that makes its way to the urbanstormwater drainage system and water bodiesmust be filtered for Total Suspended Solids (TSS),hydrocarbons and other pollutants. Credit PW-4:Stormwater Management promotes the use of filtersand interceptors that help meet specific removaltargets defined in the Credit.Stormwater CalculationsGenerally stormwater run-off will be estimatedbased on the following formula:Q = 240 x C x I x AWhere:Q = The peak run-off rate (m 3 /day).240 = conversion factor required to calculate Q inm 3 /day.C = the run-off coefficient.I = the average rainfall intensity for the selectedfrequency and for a duration equal to the time ofconcentration (mm/hr).A = the size of drainage area.The rainfall intensity must be calculated based onAbu Dhabi Intensity Duration Flow (IDF) curves. Thecoefficient of run-off is the percentage of waterwhich will run off the ground surface during a storm.The remaining amount of precipitation is lost toinfiltration, transpiration, evaporation and depressionstorage. The values of run-off coefficients fordeveloped areas used by Abu Dhabi Municipality arepresented in Table 4.Table 4: Run-off Coefficients for Developed AreasTypes of Drainage AreaRun-off CoefficientBusinessDowntown business areas 0.70-0.95Business and residential mixedareas0.50-0.70ResidentialWalled plots 0.20-0.40Single - family and villa areas 0.30-0.50Multi - units, detached 0.40-0.60Multi - units, attached 0.60-0.75Apartments (residential building) 0.50-0.70IndustrialLight areas 0.50-0.80Heavy areas 0.60-0.90Parks/cemeteries 0.10-0.25Playgrounds 0.20-0.40Unimproved areas 0.10-0.30Grassed AreasSandy soil, flat, 2% 0.05-0.10Sandy soil, average, 2-7% 0.10-0.15Sandy soil, steep, 7% 0.15-0.20Heavy soil, flat, 2% 0.13-0.17Heavy soil, average, 2-7% 0.18-0.25Heavy soil, steep, 7% 0.25-0.35PavementsAsphalt 0.70-0.95Concrete 0.80-0.95Interlocking pavers 0.70-0.85Roofs 0.75-0.95Related Credits:PW-4: Stormwater Management.Estidama - Page 25

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama3.9 External Building MaterialsAs the design of the mosque building and plot takeshape, the design team must consider appropriatematerials for external structures and building façades.Aesthetic aspirations must be able to accommodatePBRS thermal performance requirements in terms ofconstruction practicalities.Project teams may elect to follow 1 of 2 options todemonstrate compliance:• prescriptive route - details of the building materialrequirements that must be met are listed inAttachment A (Prescriptive Method Requirements); or• performance route - requires an energy model todemonstrate compliance.There are several additional requirements that must beconsidered when specifying these materials (refer toVolume 2 - Design).Achieving the Wall, Roof and Floor U-ValueRequirementsWith the extreme desert climates that exist in theregion, significant importance is placed on the use ofhigh performance building materials. The U-value is acommon measure of the ‘thermal transmittance’ of aconstruction and in simple terms represents a measureof the rate of heat transfer so that a lower U-valuerepresents increased thermal resistance.Several important considerations must be addressed tosuccessfully implement the U-value requirements listedin Attachment A. The following list is focused on wallsto demonstrate key concepts that the design teammust address:Related Credits:LBo-R3: Outdoor Thermal Comfort Strategy.LBo-1: Improved Outdoor Thermal Comfort.RE-R1: Minimum Energy Performance.• windows and doors must be excluded from thecalculation of the overall wall U-value;• the wall U-value must be the area-weighted averageof all wall constructions and thermal bridges in thebuilding (for example a mosque built using insulatedconcrete blocks must also consider the structuralareas, such as columns and thermal bridges throughmortar, when calculating the overall wall U-value);• internal walls (those with consistently identicalconditions on either side) need not meet U-valuerequirements;• care must be taken to ensure continuity of insulationwhere walls meet roofs (e.g. insulation should besuitably designed around parapets);• insulation must be provided to soffits over externalcolonnades/walkways where present;• depending on location and associated climate, theneed for suitable vapour barriers must be addressedto eliminate the possibility of interstitial condensationin the summer months; and• the use of high reflective surface coatings to reflectsolar heat away (requirements for Solar ReflectiveIndex (SRI) coatings are provided in Attachment A).Achieving Window U-value and Solar Heat GainCoefficient RequirementsWindow selection is important in relation to overallbuilding energy usage because windows generally willnot perform as well as wall constructions in terms ofU-value, however they also introduce useful light intooccupied spaces.Whilst the U-value deals primarily with conductivegains through the window, radiative heat gains are alsopresent through the glass. To address the radiative heatgains, another parameter known as the Solar Heat GainCoefficient (SHGC) is used. The requirements that mustbe met for windows are listed in Attachment A.Several important considerations must be addressed toachieve the project’s U-value and SHGC targets. Thefollowing list demonstrates the key concepts that thedesign team must address:• the U-value considers both the glass and framecomponents of windows. To simplify windowselection, a U-value limit for glass has beenprescribed which may be used when the frame isthermally broken;• window ratios for mosques must also be limited, asdetailed in Attachment A.• the designer should try to limit or eliminate directsolar radiation where possible so that daylightis introduced through the brightness of the skyrather than the sun (diffuse radiation). This can beachieved by the use of solar shading projectionsand mashrabiya panels (especially to east and westfaçades which are the hardest to shade); and• the use of after-market solar films on glass toachieve SHGC requirements must be avoided. Instead,factory applied tints or reflective or sputteredcoatings must be used.Achieving External Shading SRI RequirementsWhen providing external shading, the design teammust consider the type of shading that best suits themosque. Shade can be created using trees, structuralor temporary shades.

To achieve this, thefollowing design measures must be addressed:• location of air intakes in relation to sources ofpollution;• location of exhaust air discharges;• ventilation rate requirements;• varying demand for fresh air according to spaceusage and daily occupancy variations; and• thermal zoning strategy.Air IntakesWhen considering the location of air intakes (includingdoors and operable windows), the designer mustensure that the separation distances comply with theminimum thresholds set out in Table 5 (more detail onthese requirements is provided in ASHRAE 62.1:2007Table 5.1).Related Credits:LBi-R1: Healthy Ventilation Delivery.LBi-5.1: Thermal Comfort & Controls: Thermal Zoning.Table 5: Minimum Air Intake Separation DistancesSignificantly contaminatedexhaustNoxious or dangerousexhaustVents, chimneys, and fluesfrom combustion appliancesand equipmentGarage entry, automobileloading area or drive-inqueueTruck loading area or dock,bus parking/idling areaDriveway, street, or parkingareaThoroughfare with hightraffic volumeRoof, landscaped grade, orother surface directly belowintakeGarbage storage/pick-uparea or dumpstersAir Intake MinimumSeparation Distance(metres)510557.51.57.50.3Cooling tower intake or basin 5Cooling tower exhaust 7.55The designer must present their strategy for thelocation of air intakes. This strategy must include an airintake plan showing all sources of pollution including:• waste storage areas;• Air Handling Unit (AHU) exhausts;• toilet and kitchen air extractor units;• car parking;• driveways and streets;• roads and highways;• bus and taxi ranks;• cooling towers; and• any other notable pollution sources.To fulfil the requirements of this strategy, the designermust visit the plot before commencing design of theventilation systems to document and photographthe location of pollution sources arising immediatelyoutside the mosque plot. Distances of pollutant sourcesto the plot boundary must also be included in the airintake plan.Exhaust Air DischargesWhen determining the position of exhaust airdischarges, the designer must consider the locationof air intakes, operable windows and entrances of themosque and neighbouring buildings.Exhaust air discharges must not be located within thedefined public realm, such as pedestrian pathways, inaddition to the riwaq and sahan.Estidama - Page 28

Abu Dhabi Mosque Development RegulationsAppendix 1 - EstidamaVentilation RatesThe mosque designer must design the mechanicalventilation system in accordance with the requirementsof ASHRAE 62.1.2007: Table 6.1, relevant extracts ofwhich are shown in Table 6 below.Varying Fresh Air DemandOccupancy will vary substantially in prayer halls, multipurposehalls and Qur’anic class areas. The ventilationsystem must have the ability to accommodate varyingTable 6: Mechanical Ventilation Systemoccupancy. At a minimum, unoccupied spaces, orparts of spaces, must be capable of turning downthe provision of fresh air via response from the localthermostat controller.Larger mosques, i.e. those serving more than 1,000worshippers, should utilise CO 2sensors to determinethe fresh air demand and modulate the fresh airprovision.In all mosques, the ventilation system must bedesigned to accommodate space subdivision throughpartitioning to ensure turn down of fresh air tounoccupied spaces.By complying with these requirements, the mosque iseligible to achieve Credit LBi-R1: Healthy VentilationDelivery.Thermal ZoningThe mosque designer must design the ventilationsystem in conjunction with the thermal zoningstrategy discussed in Section 4.2, which sets outthe requirements of Credit LBi-5.1: Thermal Comfort& Controls: Thermal Zoning, and within Volume 2 -Design.1No.BuildingImam’s/Mu’athen’sResidence2 MosqueSpace/RoomTypeBedroomLiving areasOccupancy RateFirst bedroom 2; each additionalbedroom 1.Based on number of bedrooms.

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama4.2 Thermal ZoningThermal zoning is the principle of sizing on-floorsystems according to the varying peak loads within thespace. A key outcome of thermal zoning is the abilityto control HVAC systems so that occupied spaces canbe maintained at a different temperature to unoccupiedspaces without compromising occupant thermalcomfort. Appropriate thermal zoning of the interiorspaces of the mosque is important to minimise theamount of energy used in space cooling.Mosque spaces that must be considered include themale and female prayer areas, multi-purpose hall andQur’anic class areas, as all of these will experiencewidely varying occupancies throughout the year andtend to be large enough to warrant zoning.When planning for the HVAC system that will servethese spaces, the designer should establish thermalzones, with each zone having a dedicated indoorcooling unit and local thermostat controller.The size of each thermal zone should be 35m 2 to 40m 2for perimeter spaces and 70m 2 to 100m 2 for internalareas. Perimeter thermal zones along the same wallmay be combined.For larger mosques,a central Building ManagementSystem (BMS) should be installed to link with all coolingunits and thermostat controllers.Accommodating Partitioning Within theMosqueA mosque will typically cater for 5 daily prayers eachday of the year. Depending on the type of mosqueadditional prayers may need to be catered for. Theexpected occupancy density may vary from 100% forjame’e and Eid prayers, to approximately 20 to 25% forFajr prayers.Related Credits:LBi-5.1: Thermal Comfort & Controls: Thermal Zoning.Where the use of space subdivision throughpartitioning is utilised, the thermal zoning strategymust accommodate this physical sub-division of spaceby providing suitable thermostatic controls, sensorsand supply terminals to enable energy savings to bemade. The occupied space should be controlled to thedesign temperature with the unoccupied space allowedto drift to an appropriate design set-back temperature.Consideration must be given to the need for provisionof fresh air to occupied spaces and how the HVACsystem will be designed to accommodate thesevariations.AHUTFCUFCUTFCUMax 100m 2Max 100m 2Max 100m 2 Max 100m 2Max 100m 2 Max 100m 2TTRiwaqLegend:AHU Air Handling Unit (roof mounted)FCU Fan Coil UnitT Temperature sensorPartitionThermal zoneFCUFCUFCUFigure 14: Example of thermal zoning in a prayer hall.TTWhile not part of Credit LBi-5.1: Thermal Comfort &Controls: Thermal Zoning, it is expected that the designerwill also provide lighting systems with local controls thatreflect the intended space use strategy.Space subdivision is best achieved through easilymovable partitioning. Permanent partitioning can beconsidered as long as it can be demonstrated that itdoes not interfere with the primary mosque functions.In either case, the partitioning system must extend fromthe finished floor to the underside of the ceiling.Where the mosque demonstrates the requirements ofCredit LBi-5.1 Thermal Comfort & Controls: ThermalZoning have been met, it will be eligible for 1 Credit Point.Estidama - Page 30

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama4.3 Acoustic DesignThe mosque designer should demonstrate that internalambient noise levels are between 40- 50 dB(A)Leq inthe areas to be occupied within the mosque. For theImam’s residence, the internal ambient noise levelsshould be less than 35dB(A)Leq(8hour) and 45dB(A)Lmax, fast in bedrooms and less than 40dB(A) Leq inother areas.From the early stages, the building can be designed tominimise the internal ambient noise levels. This can beachieved by considering several aspects such as:Only noise from building services and external noisesources should be included in measurements andcalculations. All analyses must represent the noisiestareas of the building, typically near façades on busystreets. All calculations, measurements and acousticreports must be signed off by a qualified acousticsengineer.• location of noise sensitive areas of the building withrespect to external noise sources, such as surroundingstreets;• consideration of the air-gaps in construction andprovision of appropriate sealing measures;• location of rooftop AHUs;• provision of sound attenuators on air ducts carryingair at high velocities;• velocity of air in the ducts;• noise generated by MEP equipment;• design of internal drainage piping to reduce noise; and• use of wall insulation for minimising ambient noise.Related Credits:LBi-9: Indoor Noise Pollution.Estidama - Page 31

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama5.0 Material SelectionThe construction of a mosque uses many materials,such as concrete, metal, wood, glass, plastics andpaints. To generate these products, the raw materialsmust be extracted, processed into usable form,manufactured into assembled products, packaged andtransported before they are used in the constructionof the mosque. Repairs, renovations and modificationsto the mosque puts additional pressure on the demandfor raw materials. Regardless of which products areselected to construct a mosque, hazardous materials,such as asbestos, must not be used due to the potentialnegative health implications.During the useful life of the mosque, the permanentresidents (Imam and Mu’athen) and worshippers willconsume products and discard associated waste suchas food, paper, cardboard, bottles and plastic bags. Atthe end of the useful life of the mosque, significantquantities of demolition waste must be disposedof. According to the Center of Waste ManagementAbu Dhabi, almost 6,000,000 tonnes of wasteare generated in the Emirate every year but manymore tonnes of scarce raw materials are required tomanufacture the products.Related Credits:SM-R1: Hazardous Materials Elimination.SM-R2: Basic Construction Waste Management.SM-R3: Basic Operational Waste Management.SM-5: Modular Flooring Systems.SM-6: Design for Durability.SM-9: Regional Materials.SM-10: Recycled Materials.SM-12: Reused or Certified Timber.LBi-2.1: Material Emissions: Adhesives & Sealants.LBi-2.2: Material Emissions: Paints & Coatings.LBi-2.3: Material Emissions: Carpet & Hard Flooring.LBi-2.4: Material Emissions: Ceiling Systems.LBi-2.5: Material Emissions: Formaldehyde Reduction.Most of Abu Dhabi’s waste is currently disposed ofin dedicated areas called landfills and left to slowlydecay. Unfortunately some waste is illegally dumpedin unauthorised locations. Both of these practices havemany negative impacts:• pollution of the local environment - groundwater andsoil contamination;• production of methane, a potent greenhouse gas, bywaste decay;• injuries to local wildlife;• harbouring of disease by rats and flies;• environmental noise;• odour; and• dust.The following items are the topics covered by thePBRS which should be addressed when designing anymosque. These topics begin to address the challenge ofreducing our impact on the world’s natural resources,the environmental impacts associated with our actionsand providing spaces which do not harm its residentsand visitors.Hazardous MaterialsThe mosque must eliminate the use of asbestos andChromated Copper Arsenate (CCA) treated timber.Low Emission MaterialsAdhesives and sealants, paints and coatings, flooringand ceiling systems should be specified to reducethe quantity of odorous and harmful indoor aircontaminants. All internal construction materials andinstalled furniture should not exceed formaldehydecontent class E1 levels.Construction WasteA Construction and Demolition Waste Management Plan(CDWMP) must be in place in order to identify methodsof waste collection, transport and disposal. The CDWMPmust identify the materials to be diverted from landfilland indicate whether the materials will be segregatedon-site or commingled. If materials are planned forsalvage, the CDWMP must indicate their planned use.Operational WasteAn Operational Waste Strategy (OWS) must be in place inorder to identify methods of waste collection, transportand disposal. Adequately sized and accessible facilitiesand clearly labelled containers must be provided for thestorage and collection of source-segregated waste.Modular MaterialsWaste associated with the replacement of flooringsystems should be minimised through the use ofmodular flooring systems.Durable MaterialsA Building Durability Plan (BDP) should be developedand implemented to optimise the integrity ofthe building envelope. The BDP should addresscondensation, water ingress, improper drainage and theprotection of vulnerable areas of the building envelope.Recycled MaterialsRecycled steel and aggregate, as well as an alternativeto Portland cement, should be used in order to reducethe amount of waste going to disposal.Regional MaterialsAir-freighted materials should be avoided and buildingmaterials with a reduced transport impact, as well asthose which promote regional economies, should beselected.Estidama - Page 32

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama5.1 Modular Flooring SystemsThe use of modular flooring systems (carpets and tiles)reduces the amount of waste associated with replacinglarge areas of flooring that is damaged due to accidentor general use. Modular flooring systems provide asolution to this as only the section of flooring that isdamaged requires replacement, hence reducing theamount of waste generated.In order to provide comfort during prayer, and to assistwith the cleanliness of the mosque, the main areasin mosques are covered in carpet. This provides anexcellent opportunity to implement a modular flooringsystem (carpet) (refer to Volume 2 - Design).The mosque designer must specify that a minimumof 95% of all flooring systems in the mosque is laidwith a modular flooring system. In addition, themodular flooring system must meet 1 of the followingrequirements of Credit SM-5: Modular FlooringSystems:• a minimum of 30% post-consumer recycled content;• be fully or partly recyclable;• be rapidly renewable; or• be extracted, harvested or recovered andmanufactured locally as required by Credit SM-9:Regional Materials.Where the mosque designer and/or contractorcan demonstrate the above requirements are metthrough the submission of drawings, carpet or tilespecifications, the mosque is eligible to achieve 1Credit Point under SM-5: Modular Flooring Systems.Figure 15: Example of a modular flooring system in a mosqueRelated Credits:SM-5: Modular Flooring Systems.Estidama - Page 33

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama5.2 Design for DurabilityThe intention when constructing a mosque is for thebuilding to last as long as possible with minimummaintenance and replacement of building systems.Therefore it is very important that the mosque designerand contractor take the necessary steps to ensurethat vulnerable building elements are not exposed todamage.The type of damage that a mosque could endure rangesfrom structural damage through to water damage,and must be protected through appropriate design,commissioning, building performance verification andsound construction techniques.In order to be eligible for 1 Credit Point under CreditSM-6: Design for Durability, the mosque designermust submit a narrative which describes the followingmeasures, which must be undertaken/implementedduring the design and construction of a mosque:• waterproofing of drains and ablution areas: themosque designer and/or contractor must detail theprocedure for waterproofing all drainage and pipingwithin the mosque. This is to protect the buildingfrom leaks from the drainage and water pipes of themosque. The water supply systems in the ablutiontoilet areas must be included as these are areas witha high likelihood of water leakage.• condensate capture: the mosque designer shouldspecify that all AHUs and FCUs have appropriatecondensate capture capabilities. Build-up ofcondensate can lead to water leakage and causedamage to ceiling systems and flooring/carpets;• crash protective system: bollards should be designedin order to prevent vehicular crash damage tostructural and façade elements of the mosque; andRelated Credits:SM-6: Design for Durability.Estidama - Page 34

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama6.0 Design of Building SystemsThrough principles of passive design, the design teammust arrive at the optimal mosque envelope andmassing design based on the plot context. The designof the mechanical and ventilation, electrical and lightingsystems and associated controls will have a largeimpact on the energy consumption of the mosque. As aresult of the IDP, the indoor space of the mosque mustbe healthy, comfortable and functional.For all building systems, the mosque designer shouldmeet all the requirements detailed within the followingsections of the Abu Dhabi International EnergyConservation Code:• Section 503 – Building Mechanical Systems;• Section 505 – Electrical Power and Lighting Systems;and• Section 506 – Additional Efficiency Package Options.EnergyThe design of the building HVAC and lighting systemsis driven by the requirements outlined in the AbuDhabi International Energy Conservation Code -Sections 503 and 505. Compliance with Credit RE-R1:Minimum Energy Performance must be demonstratedby either following a prescriptive path or by dynamicsimulation modelling of the proposed design as per theASHRAE 90.1 Appendix G Performance Rating Method.The performance path must demonstrate a 12%Related Credits:IDP-R1: Integrated Development Strategy.LBi-R1: Healthy Ventilation Delivery.LBi-R3: Legionella Prevention.PW-R1: Minimum Interior Water Use Reduction.PW-R2: Exterior Water Monitoring.RE-R1: Minimum Energy Performance.RE-R2: Energy Monitoring & Reporting.RE-R3: Ozone Impacts of Refrigerants & Fire Suppression Systems.improvement when compared with a baseline case.Credit RE-R2: Energy Monitoring & Reporting, requiresthe installation of easily accessible and clearly labelledenergy sub-meters to measure, at a minimum, 90%of the estimated annual energy consumptions of eachfuel type (electricity, gas, etc.) for all energy enduse categories, in both the Imam’s residence (andMu’athen’s residence if applicable) and the public areasof a mosque. Metering is also required for all on-siteenergy generating systems and large plant items.Through the careful selection and specification ofcommon building appliances and light fixtures (internaland external), the mosque designer can reduce theenergy consumption of the mosque. The designer canalso minimise the impact on the environment throughcareful selection of refrigerants and fire suppressionsystems within the plot boundary. All refrigerants andgaseous fire suppression systems must have an ozonedepletion potential of zero.WaterEfficient water fixtures and metering are requiredas per Credits PW-R1: Minimum Interior Water UseReduction and PW-R2: Exterior Water Monitoring.The Estidama PBRS Manual provides maximum flowrates or quantities for water fixtures, fittings andappliances. Credit PW-R2: Exterior Water Monitoringrequires the installation of easily accessible and clearlylabelled sub-meters for the building’s external wateruse. These sub-meters should have a pulsed outputand be capable of remote monitoring.Potable water demand should be minimised through:• minimising landscaping water demands througheffective plant selection, irrigation strategies and theuse of recycled water;• use of recycled water for heat rejection; and• minimising evaporative loss through the use ofrecycled water in exterior water features.LegionellaThe management of Legionella bacteria is discussedin Credit LBi-R3: Legionella Prevention.

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama6.1 Energy SystemsAir Conditioning and Mechanical VentilationAlthough the cooling requirements of a mosque willbe reduced by minimising heat gain through windows,walls and roofs and by reducing infiltration, energyis still required to condition internal spaces. Efficientsystem performance is therefore a critical factor inachieving reductions in energy usage (refer to Volume2 - Design).For most buildings, the performance of the airconditioningsystem is based on:• the efficiency of energy conversion from electricity tocooling, which is typically provided by localised units,central chillers or district cooling;• the effectiveness of the fans providing air to thespaces (both fresh and re-circulated air);• the selection of appropriate sensors and controls forvarious system elements in different zones (refer toSection 4);• the response of the system to variation in thermalloads and occupant requirements (refer to Section 4);and• the inclusion of energy recovery and other efficiencymeasures.LightingGood lighting design can reduce energy usage internallyand externally. Internal lighting energy is restrictedon a basis of power used per unit area. Externallighting energy is also restricted in a similar way.Energy allowances are outlined in section 9 of ASHRAEStandard 90.1:2007.Demonstrating Minimum Energy PerformanceComplianceThe mosque designer must demonstrate that themosque energy performance is in compliance withthe requirements of Credit RE-R1: Minimum EnergyPerformance. There are 2 paths to demonstratecompliance:• Prescriptive Path: The mosque designer is required tofully comply with the design requirements outlinedin Volume 2 - Design. Additional requirements onthe envelope, HVAC systems and lighting to complywith Credit RE-R1: Minimum Energy Performanceare listed in Attachment A of this appendix.• Performance Path: The mosque designer is requiredto develop an energy model of the proposed mosquedesign using dynamic simulation modelling software.A minimum 12% performance improvement mustbe achieved when compared to a baseline buildingperformance as per the building performance ratingmethod outlined in Appendix G of ASHRAE Standard90.1:2007.Related Credits:LBi-R1: Healthy Ventilation Delivery.RE-R1: Minimum Energy Performance.Estidama - Page 47

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama6.4 Lighting FixturesInternal Lighting FixturesIncandescent lamps produce light by heating aninternal filament to approximately 2,500-3,000°C,the temperature at which visible light is emitted. Asa result, incandescent lamps generate a lot of heatwhich places significant demand on a building’s airconditioning system. Today, incandescent lamps arebeing phased out internationally in favour of moreenergy efficient lamps.Fluorescent lamps have gained in popularity since themiddle of the 20th century and are now commonplacein most buildings. Ever since fluorescent lighting wasfirst introduced, there have been negative healthcomplaints relating to headaches, eye strain andgeneral eye discomfort. These complaints have beenassociated with the light flicker from these lights.When compared to regular fluorescent lights, the useof high frequency electronic ballasts (20-60kHz) influorescent lights resulted in a significant drop in thesecomplaints.When designing and specifying high frequencyelectronic ballasts, the design team should engage withlocal supply chain professionals and together assessagainst the following criteria 1 :• Starting method (e.g. rapid-start, instant-start,programmed start);• Ballast factor;• Power factor;• Total harmonic distortion;• Lamp-ballast compatibility;• Inrush current; and• Ballast reliability.The design team should not specify the use ofincandescent lamps in any part of the mosque building.In addition, all permanently installed fluorescentlighting installations should incorporate high frequencyelectronic ballasts. Projects will be eligible for 1 CreditPoint in Credit LBi-6: High Frequency Lighting. Inaddition, the design team must ensure that lightingpower densities and controls are provided that meetthe requirements in Attachment A.External Lighting FixturesThe design team must ensure that all externallighting meets the requirements of ASHRAE Standard90.1:2007.

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama6.5 Refrigerants and Fire Suppression SystemsThe ozone layer protects the earth’s surface fromdamaging radiation. Many of the refrigerants currentlyused in air conditioning systems cause damage to theozone layer. This environmental impact can be reducedby the appropriate selection of refrigerants and firesuppression systems with a zero Ozone DepletionPotential (ODP).Credit RE-R3: Ozone Impacts of Refrigerants & FireSuppression Systems, requires that refrigerants andgaseous fire suppression systems installed within theplot have a zero ODP.This requires avoiding refrigerants such as HCFC-22,which will not be banned within the UAE until 2015,but should not be used due to its ODP properties.Refrigerants with an ODP of zero are required, such asHFC-134a.An example of a gaseous fire suppression agent isNovec 1230. It is an environmentally-friendly Halonreplacement and has an ODP equal to zero.Table 18: Refrigerants and Fire SuppressionChlorofluorocarbon ODP GWP Common Building ApplicationsCFC - 12 1.0 10,900 Refrigerators, chillersHydrochlorofluorocarbonsHCFC - 22 0.055 1,810 Air conditioning, chillersHCFC -123 0.02 77 CFC-11 replacementHydrofluorocarbonsHFC - 134a 0 1,430 CFC-12 or HCFC-22 replacementHFC - 2227a 0 3,500 Fire suppression refrigerantHFC - 245fa 0 1,030 Insulation agent, centrifugal chillersHFC - 407c 0 1,700 HCFC - 22 replacementHFC - 410a 0 1,900 Air conditioningHFC - 417a 0 1,950 HCFC - 22 replacementNatural RefrigerantsCarbon Dioxide (CO2) 0 1.0Ammonia (NH3) 0 0Propane (C3H8) 0 3Isobutene 0 3Air 0 0Water 0 0 Related Credits:RE-R3: Ozone Impacts of Refrigerants & Fire Suppression Systems.Estidama - Page 51

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama6.6 Water Fixtures and AppliancesOptimising Interior Water ConsumptionThe interior water consumption within the mosqueis related to the efficiency of the water fixtures andappliances that are selected. The most significantinterior water consumption patterns are likely to beattributed to ablution and toilet use so selecting unitsthat improve upon the minimum requirements of thePBRS will have the biggest impact.To comply with Credit PW-R1: Minimum Interior WaterUse Reduction, the project must demonstrate that theproposed mosque’s interior water consumption is lessthan or equal to the mosque’s baseline interior waterconsumption. The baseline water consumption is set atthe performance figures in Table 19. The Mosque WaterCalculator must be used to demonstrate compliancewith Credit requirements and can be obtained fromwww.estidama.org.The following pages contain screenshots of the tabswithin the Mosque Water Calculator. This will help thedesign designer enter information correctly.Water Demand Rates‘Trade-off’ between water fixtures and fittings is notpermitted, meaning that each fixture must at leastequal the performance requirements shown in Table19. Interior water consumption savings that lead toCredit Points for Credit PW-1: Improved Interior WaterUse Reduction can only be obtained by using higherperformance water fixtures and by installing infra-redor metering controls to selected fixtures. The mosquedesigner must consider appropriate fixtures that meetthese requirements and document compliance throughthe Mosque Water Calculator specifications that clearlylist performance requirements, and/or product datasheets.Related Credits:PW-R1: Minimum Interior Water Use Reduction.Table 19: Required Water Demand RatesFixture or FittingBathroom taps, privateBathroom taps, publicShowerheadKitchen sink faucetBidets/bidet spraysUrinalsToilets (dual flush)DishwashersWashing machinesCondensation RecoveryMaximum Flow Rate or Quantity6 litres/min at 413.7 kPa (reference pressure)1.9 litres/min at 413.7 kPa (reference pressure)9.5 litres/min at 551.6 kPa (reference pressure)6 litres/min at 413.7 kPa (reference pressure)6 litres/min at 413.7 kPa (reference pressure)0.5 litres/flushing cycle6/4 litres/flushing cycle (full/low)1.3 litres/place setting8.5 litres/kg of dry loadCondensate water comes from cooling systems such asAir Handling Units (AHU) and Fan Coil Units (FCU).

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama6.8 Design for Legionella PreventionLegionnaires’ disease is a potentially fatal form ofpneumonia which can affect anybody, but whichprincipally affects those who are susceptible becauseof age, illness, immune-suppression or smoking.People can catch Legionnaires’ disease by inhalingsmall droplets of water suspended in the air whichcontain the bacteria. Legionella bacteria are commonlyencountered in water systems, such as cooling towersystems and hot and cold water systems, and otheritems which use or store water.The bacteria are dormant below 20°C and do notsurvive above 60°C. Certain conditions increase therisk from Legionella bacteria:• a suitable temperature for growth, 20 to 45 o C;• a source of nutrients for the organism, eg sludge,scale, rust, algae and other organic matter; and/or• a way of creating and spreading breathable droplets,e.g. the aerosol created by a cooling tower or spraynozzle.To reduce the possibility of creating conditions inwhich the risk from exposure to Legionella bacteria isincreased, it is important to control the risk. Hot andcold water systems should be designed to aid safeoperation by preventing or controlling conditions whichpermit the growth of Legionella bacteria and alloweasy cleaning and disinfection.Since many critical decisions need to be made atthe design stage, the design team must considerthe following when developing the mosque and itsfacilities:• ensure water cannot stagnate anywhere in thesystem, e.g. remove redundant pipework and runtaps/showers in unoccupied rooms;• keep pipework as short and direct as possible;• keep water cisterns covered, insulated, clean and freeof debris;• adequately insulate pipework and keep away fromhot ducting and other hot piping to prevent excessivetemperature rises in the cold water supply; typicallynot more than a 2°C increase should be allowed;• hot water storage cylinders (calorifiers) should storewater at 60°C or higher;• hot water should be distributed at 50°C or higher(thermostatic mixer valves need to be fitted as closeas possible to outlets where a scald risk is identified);• the pipe branches to the individual hot taps should beof sufficient size to enable the water in each of thehot taps to reach 50°C within one minute of turningon the tap;• cold water storage tanks should be sited in a coolplace and protected from extremes of temperature bythermal insulation. Cold water should be stored anddistributed below 20°C;• ensure that calorifiers are fitted with shunt pumps toprevent thermal stratification within the calorifiers;• advise maintenance staff working on the systemabout the risks and how to minimise them; and• advise tenants about the risks and the controlmeasures/precautions they can take, such as flushingthrough showers following a period of non-use.Related Credits:LBi-R3: Legionella Prevention.Estidama - Page 57

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama7.1 Construction Environmental ManagementWorks undertaken by the mosque contractor duringthe building stage may adversely impact amenities,traffic or the environment of the surrounding areaif site-specific and implementable procedures andmitigation measures are not put in place to monitor andcontrol these environmental impacts throughout theconstruction phase.The Federal Environment Law No. 24 of 1999 forthe Protection and Development of the Environment(Federal Law 24) stipulates the need to evaluate theenvironmental impacts of all development projectsundertaken in the UAE. In accordance with theLaw, the Environment Agency - Abu Dhabi (EAD),is responsible for determining the environmentalpermitting requirements for all new developmentswithin the Emirate of Abu Dhabi.They are also responsible for evaluating EnvironmentalPermit Applications (EPA) for all new constructionprojects prior to commencing any construction works.Following this and depending on the complexity,location and existence of sensitive receptors in theproximity of the proposed mosque, the EAD mayrequire various studies to be prepared and submittedfor review and approval (more details on these can befound at: http://www.ead.ae/en/portal/environmental.permitting.aspx) before issuing the contractor with thebuilding permit.Amongst the required studies, the EAD may requirethe mosque developer and contractor to prepare andimplement a Construction Environmental ManagementPlan (CEMP) in accordance with the EAD’s TechnicalGuidance for CEMP.The PBRS also requires that the design anddevelopment team assess the impact of constructionand recommend that a CEMP is completed.Developer RequirementsThe Environmental Permit Application should besubmitted to the EAD by the mosque developer priorto construction works commencing on site. Afterreviewing the EPA, the EAD will issue a response tothe mosque developer, either issuing a ‘No ObjectionCertificate’ (NOC) or requesting the preparation andimplementation of an Environmental Study to issue thenecessary permit.To comply with the requirements of Credit IDP-3: Construction Environmental Management, themosque developer should include within the tenderdocumentation the requirement that all contractorstendering for the mosque construction develop andimplement a CEMP that meets the Credit requirements.Contractor RequirementsSimilarly, the mosque contractor should take intoaccount the requirement to prepare and implementa CEMP for the mosque development prior to anyconstruction works commencing on-site.In the case that the EAD issues a formal request toprepare a CEMP for the mosque development, thecontractor should have a CEMP prepared by an EADapprovedand registered consultant in accordance withthe EAD’s Technical Guidance for CEMP and obtainEAD’s approval on the CEMP.In the case that the EAD does not require a CEMP to beprepared for the mosque development, the contractorshould still have a CEMP prepared by an EAD-approvedand registered consultant in accordance with the EAD’sTechnical Guidance for CEMP and submit this to theUPC for approval.In both cases, if the above is fulfilled to therequirements of Credit IDP-3: ConstructionEnvironmental Management, 1 Credit Point can beachieved.Related Credits:IDP-3: Construction Environmental Management..Estidama - Page 59

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama7.2 Construction Waste ManagementBefore starting any demolition or construction, it isnecessary to develop a Construction and Demolition(C&D) Waste Management Plan. This shouldincorporate:• estimates of waste generation. The Building WasteCalculator will help to estimate the type and amountof waste expected for the project. This can bedownloaded from the Estidama website;• a destination for each waste type leaving the plot.

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama8.0 Performance VerificationThe key to ensuring the sustainable performanceof a mosque is to verify that the building performsaccording to the design criteria.As per the requirements of Credit IDP-R3: BasicCommissioning, an independent commissioning agentmust verify that the building performs as designedto protect occupant health and to ensure on-goingbuilding efficiency. This agent must be engaged fromthe beginning of design through to the completionof construction and commissioning. The design andconstruction documentation must be reviewed by thecommissioning agent prior to the start of constructionworks.Information collected from the energy and watersub-meters, required by Credits RE-R2: EnergyMonitoring & Reporting and PW-R2: Exterior WaterMonitoring, must be used to inform the Awqafappointedmaintenance contractor of any performanceproblems. As per the Integrated Development Processimplementation strategy, the Awqaf-appointedmaintenance contractor must take remedial action andensure optimum operations as per the design intent.A noise field test should be conducted to ensurethat acoustic conditions are compliant with therequirements of Credit LBi-9: Indoor Noise Pollution.Related Credits:IDP-R1: Integrated Development Strategy.IDP-R3: Basic Commissioning.LBi-9: Indoor Noise Pollution.Estidama - Page 64

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama8.1 CommissioningBasic commissioning aims to ensure that thebuilding performs as designed to protect occupanthealth, provide comfort and ensure ongoing buildingefficiency. An independent commissioning agent,reporting to the project owner, with at least 2 yearscommissioning experience, must be engaged as partof the project design team from the beginning ofdesign through to the completion of construction andcommissioning (see Figure 30).The commissioning process must check, at a minimum,the following systems:• heating, ventilation, air conditioning and refrigeration;• on-site energy generation (including co-generation);• Building Management Systems;• lighting and lighting controls;• domestic hot and cold water systems;• on-site water treatment systems; and• automated control features such as blinds.Within the mosque Operations and MaintenanceManuals, the following sections would normally beexpected:• annual review and updates to the manuals;• purpose and responsibilities;• links to other key documents;• main contacts;• commissioning, handover and compliance;• overall building design;• summary of areas/occupancy;• summary of main MEP plant;• overview of controls/BEMs;• builder user information (requirement dependent onbuilding typology);• metering, monitoring and targeting strategy;• building performance records;• summary of maintenance requirements;• major alterations;• results of in-use investigations; and• appendices - all relevant certificates/tests.A commissioning plan should include the following:• commissioning programme overview;• list of systems and assemblies included incommissioning process and activities;• commissioning team and responsibilities;• management, communication and reporting ofcommissioning process;• overview of commissioning process activities throughthe design, including:• design and construction document review;• basis of design review;• owner’s (donor/Awqaf) project requirements;• submittals documentation and process; and• functional performance test development and8.2 Acoustic Verificationimplementation.The purpose of a mosque is to provide a quiet andcomfortable place for worshippers to pray withoutdistractions from the outside world. It is alsoimperative that the words from the Imam can be heardclearly.The contractor should submit testing results of noisemonitoring that demonstrate the following:• Internal ambient noise levels do not exceed 50 dB(A)Leq within the public prayer areas; and• Internal ambient noise levels do not exceed 35 dB(A)Leq (8-hour) and 45 dB(A)Leq max in the bedroomsof the Imam’s and Mu’athen’s residences and lessthan 40 dB(A)Leq in all other areas of the residences.During testing, only noise from building services andexternal noise sources should be included and the testshould represent the noisiest area of the buildings.This testing process must be signed off by a qualifiedacoustics engineer.Related Credits:IDP-R3: Basic Commissioning.LBi-9: Indoor Noise Pollution.Estidama - Page 65

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama9.0 Mosque OperationThis section addresses the operations and maintenanceaspects related to the mosque. Once the mosque hasbeen built according to the sustainability featuresestablished during design, it is important to ensurethat these sustainability measures are maintainedfor the life of the mosque to ensure that the mosquecontinually operates efficiently.The operation and maintenance of the mosque islikely to be undertaken by 2 parties: the Imam andthe Awqaf-appointed maintenance contractor. Itis important throughout the design process that arepresentative from the Awqaf-appointed maintenancecontractor is made aware of any major designconsiderations that are likely to have specific operationand maintenance requirements for the mosque (refer toVolume 3 - Operations).The operation of the mosque must follow the principlesof Estidama in the following key areas:• communication of sustainable design features andoperational requirements;• management of natural systems according to theNatural Systems Design and Management Strategy;• waste management; and• Legionella management.There may be documents or processes which havebeen produced or followed for Estidama submission.The following section outlines these for the mosqueoperators.Related Credits:IDP-R1: Integrated Development Strategy.IDP-6: Sustainability Communication.NS-R3: Natural Systems Design & Management Strategy.LBi-R2: Smoking Control.SM-R3: Basic Operational Waste Management.SM-14: Improved Operational Waste Management.LBi-R3: Legionella Prevention.Estidama - Page 67

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama9.1 Sustainability CommunicationIn order for the mosque to operate efficiently andperform to the criteria set out in the design stagefor mosque development, it is vital that the mosqueoccupants are made aware of the effect they have onthe performance of the mosque. Water usage throughablution and waste generation are some of the keyareas that are impacted by worshipper behaviour.ApproachIt is expected that all mosques will provide a form ofcommunication to worshippers regarding the buildingperformance. The developer should propose a mediumwhich allows the performance of the mosque to becommunicated to worshippers.The digital feedback system should be located inprominent areas with high visibility to all worshippers(e.g. the mosque entrance) but must not distract orinterfere with prayer (refer to Volume 2 - Design).The provision of a digital feedback system willcommunicate the performance of the mosque toworshippers and empower them to change theirbehavioural attitudes when it comes to energy andwater saving. If a worshipper sees that their mosqueis performing below a pre-established benchmark,they should be encouraged to positively alter theirbehaviour.Digital Feedback SystemTo obtain Credit Points under Credit IDP-6:Sustainability Communication, the mosque developercan, in coordination with the UPC, install a digitalfeedback system with a dashboard display whichcommunicates the following to worshippers:• mosque energy consumption: separating out theusage against targets of the separately metered areas(e.g. prayer halls, a/c, as required by Section 6.2energy metering); and• mosque water consumption: separating out theusage against targets of the separately metered areas(e.g. ablutions, Imam’s/Mu’athen’s residences andirrigation).Related Credits:IDP-6: Sustainability Communication.Estidama - Page 68

Abu Dhabi Mosque Development RegulationsAppendix 1 - Estidama9.2 Indoor Waste and Recycling StorageInternal Waste StorageMosques have 2 separate ‘areas’ in relation to wastestorage and the type of waste generated. There arethe public prayer areas, and the Imam’s/Mu’athen’sresidences.• Public Areas: A suitable number of waste storagebins must be provided in appropriate locations (e.g.away from prayer areas or near the mosque entrance)within the public areas. These waste storage binsmust only provide for the collection of light personalwaste and must be signed appropriately.The mosque designer must provide an adequatelysized and accessible external recycling storage areawith clearly labelled bins which allow for segregationof waste. This area must be appropriately signedas described within Section 3.5 External Waste andRecycling Storage.• Imam’s/Mu’athen’s Residences: In relation to the PRSstructure, the Imam’s and Mu’athen’s residences aresubject to the requirements of the Pearl Villa RatingSystem (PVRS). The management of operationalwaste in the Villa Guidelines is covered underCredit SM-R3: Storage and Collection of Wasteand Recyclables. The provision of adequately sizedcupboard space in the kitchen area of the privateresidences is required for a minimum of 3 litterbins, or 1 combi-litter bin, with a minimum of 3compartments, to facilitate source-segregation.CollectionThe collection and transportation of waste from wastestorage bins to the external recycling storage area mustbe undertaken as follows:• Public Areas: The Awqaf-appointed maintenancecontractor will be responsible for the operation andmaintenance of the mosque and therefore will beresponsible for the collection and transfer of all wastefrom the public areas of the mosque to the externalrecycling storage area. The mosque developer/designer must discuss the waste management forthe mosque’s public areas with the Awqaf-appointedmaintenance contractor and develop an appropriateOperational Waste Strategy.• Imam’s/Mu’athen’s Residences: The collection andtransfer of waste from the Imam’s/Mu’athen’sresidences to the external recycling storage areawill be the responsibility of the occupants (e.g.Imam/Mu’athen). They will be responsible for thesegregation, collection and transfer of waste intothe appropriate labelled storage bins located in theexternal recycling storage area.Figure 31: Examplpe of waste segregation at source.Related Credits:SM-R3: Basic Operational Waste Management.SM-R3: Storage & Collection of Waste and Recyclables (1 Pearl Villa RatingSystem).Estidama - Page 69

Abu Dhabi Mosque Development RegulationsAppendix 01 - Estidama9.3 Legionella ManagementLegionnaires’ disease is a potentially fatal form ofpneumonia which is caused by Legionella pneumophila,a waterborne bacterium that grows in slow moving orstill water.HSE Approved Code of Practice (ACoP) L8:Legionnaires‘ Disease - The Control of LegionellaBacteria in Water Systems applies to plant and watersystems which may present a particular potential riskby releasing a spray or aerosol during operation ormaintenance.Relevant water-based systems include, but are notlimited to:• water systems incorporating a cooling tower or anevaporative condenser;• hot and cold water systems;• other plant and systems containing water which islikely to exceed 20ºC and which may release a sprayor aerosol during operation or during maintenance;• humidifiers;• air washers;• wet scrubbers;• fountains and water features (indoor and outdoor);• sprinkler and hose reel systems; and• spray nozzles on water fixtures.contain a spray tap to optimise water consumption.Spray taps however present a potentially high riskof harbouring Legionella bacteria. The design teammust specifically address these items in the LegionellaManagement Plan.Roles and ResponsibilitiesThe design engineers should support the client indeveloping a Legionella Management Plan including thedesign intent and Operations Manual.HSE ACoP L8 requires the appointed operationsmanager (in this instance the Awqaf-appointedmaintenance contractor) to ensure that allresponsibilities are clearly defined, formally allocatedand control procedures are carried out to preventthe growth of Legionella bacteria through theimplementation of the Legionella Management Plan.Ablution and Toilet FixturesAll ablution and toilet fixtures within the mosque mustRelated Credits:LBi-R3: Legionella Prevention.Figure 32: Control of Legionella bacteria.Source: Appendix 1, HSC - Legionnaires’ Disease.

Abu Dhabi Mosque Development RegulationsAppendix 1 - EstidamaLegionella Management PlanAt all stages of the mosque development, adequatemeasures should be implemented to minimise the riskof contamination. A Legionella Management Plan mustbe developed at the outset of the project and shouldaddress the following:1Identify and assess the level of risk associatedwith water systems in the design and operationof the mosque. If the risks are insignificant,no further action needs be taken, other thanperiodical reassessment in case of changes inthe system.2If a risk is identified, proper controls mustbe introduced and documented within theLegionella Management Plan. Risks can becontrolled by careful planning, managementpolicy, competent staff and adherence to propercontrol strategies.3Prevent or control the risk of exposure toLegionella bacteria. Consideration should begiven to:• Ensure that the release of water spray isproperly controlled;• Keep the system and the water in it clean;• Avoid conditions that favour the growth ofLegionella bacteria and other micro-organisms,water stagnation and materials encouraginggrowth;• Treat water to either kill Legionella bacteria(and other micro-organisms), limit theirability to grow, or use a biocidal treatment ifapplicable; and• Continually monitor all water systems wheresources of Legionella could occur.• Ensure easy access for inspection, draining,dismantling and cleaning of all systems.4Records need to be kept of the Plan and who isresponsible for managing it, these should also bekept with the results of the routine monitoring.5Ensure that information from manufacturers,suppliers and installers provides guidance andincludes risks to users.Figure 33: Typical Legionella bacteria risk report.Figure 34: HSC - Control of Legionella bacteria in watersystems: audit checklist.Related Credits:LBi-R3: Legionella Prevention.Estidama - Page 71
