1 Pearl Building Guide for consultants Version 1 November 2010
Introduction Intr oduction to Estidama Estidama, which means ‘sustainability’ in Arabic, is the initiative which will transform Abu Dhabi into a model of sustainable urbanization. Its aim is to create more sustainable communities, cities and global enterprises and to balance the four pillars of Estidama: environmental, economic, cultural and social. The aspirations of Estidama are incorporated into Plan 2030 and other Urban Planning Council (UPC) policies such as the Development Code. Estidama began two years ago and is the first program of its kind that is tailored to the Middle East region. In the immediate term, Estidama is focused on the rapidly changing built environment. It is in this area that the UPC is making significant strides to influence projects under design, development or construction within the Emirate of Abu Dhabi. The Pearl Rating System for Estidama is one of the key tools for driving and determining sustainable development. The completion of the Pearl Rating System for Communities, Buildings and Villas marks a critical step in the progression of Estidama by providing a suite of tools that will be the basis for sustainable development from master plan to plot.
Four pillars of estidama
Introduction to Estidama the pearl rating system for estidama
estidama for buildings
The Pearl Rating System for Estidama aims to address the sustainability of a given development throughout its lifecycle from design through construction to operation. The System provides detailed requirements for rating a building’s potential performance in relation to the four pillars of Estidama.
As of September, 2010, all new buildings in Abu Dhabi will have to achieve a minimum 1 Pearl Rating. This means that design teams will have to demonstrate that each of the required credits of the Pearl Building Rating System will be achieved. These required credits are as follows:
The Pearl Rating System is organized into seven categories that are fundamental to more sustainable development. Integrated Development Process: Encouraging cross-disciplinary teamwork to deliver environmentally sustainable solutions for the built environment. Natural Systems: Conserving, preserving and restoring critical natural environments and habitats. Livable Buildings: Ensuring quality of outdoor and indoor spaces. Precious Water: Reducing water demand and encouraging alternative water sources. Resourceful Energy: Promoting energy conservation through passive design measures, energy efficiency and renewable sources. Stewarding Materials: Reducing the impact of building materials extraction, manufacturing, transportation and disposal. Innovating Practice: Encouraging innovation and cultural expression in building design and construction to facilitate market and industry transformation.

In addition to the 20 required credits, the Rating System includes 66 optional credits. By pursuing these credits, building development teams can elect to pursue a voluntary rating as high as Five Pearls. Government-funded buildings are required to achieve a minimum 2 Pearl Rating. The detailed requirements of the required and optional credits are listed in the Pearl Building Rating System, available for download at www.estidama.org. The Pearl Building Rating System applies to all non residential buildings and multi residential buildings of more than three stories above grade.
How to use this guide This 1 Pearl Building Guide is intended to complement the Pearl Building Rating System, which is the primary reference document for Estidama compliance. This document provides guidance to a project team for achieving the required credits. Key features of the document organization are highlighted below.

1.0 Organise team + work
Related Credits: IDP-R1: Integrated Development Process
Before beginning the design and development process, the team should be organized in a way that integrates the contribution of different trades and specialities. This coordination, called an Integrated Development Process (IDP) in the Pearl Rating System, is simply a framework to support the development of holistic, creative, and efficient design solutions. The Pearl Rating System requires an IDP to extend throughout the project life cycle from inception to design, construction and commissioning.
Approach
Process
An IDP can be the foundation of a successful project team, bringing out the best input of each member. In particular, once the project team has been assembled, it facilitates the development process by:
As the project team organizes its schedule, an IDP framework should be incorporated into the development process. This framework can be broken down into four steps, which are detailed on the following pages.
• Dening a Sustainability Framework with a clear vision and objectives and specific indicators and targets to monitor ongoing performance. By establishing goals early and holding themselves accountable to these, the project team can meet ambitious goals more efficiently and avoid any incidental slippage in project performance.
12 3 4 assemble integrated development team
establish initial vision, objectives and targets
hold regular design workshops for collaboration
• Enabling true Collaboration within the project team. By discussing project goals early on and meeting face-to-face as a single group, the project team will be able to coordinate work smoothly and make decisions more rapidly. This is especially valuable as new members join the development team. • Ensuring Continuity between work packages or project stages can be achieved through effective communication and contractual arrangement. • Promoting System Thinking when developing strategies and solutions. By considering the synergistic solutions, the project team can deliver a high performing building more creatively, and without expensive technological “add ons.”
System Thinking
develop an implementation strategy for continuity
1.1 Assemble integrated development team The Integrated Development Process (IDP) aims to foster creativity and coordination in the project design and development. Therefore, an IDP should involve all members of project team, especially the client/owner or financial decision maker. A building project team in its simplest form will comprise of an Owner, an Architect, an Engineer, a Contractor, and a Commissioning Agent. Typically the Contractor will be responsible for all subcontractors. Specialists may also be brought onboard to undertake specialized work in areas such as, landscape architecture, interior design, ecology or energy modelling. A Pearl Qualified Professional (PQP) is required to integrate the collective inputs of all team members, facilitate the rating process and provide quality assurance to submissions.
Example 1.1a

The IDP process should be coordinated by a member of the design team who is qualified as a PQP. It is not necessary that this person be a dedicated sustainability consultant. He or she could be any member of the design team. More information about becoming a PQP is available at www.estidama.org.
3
Every member of the project team should contribute to the design. In order to develop more integrative ideas, team members should consider themselves collaborators in the design, even before the Architect puts pen to paper. Although the Contractor is typically involved later in the process, they should be involved as early as possible.

1.2 Establish initial vision + objectives + targets The most important aspect of an IDP is a shared vision and targets established to achieve it. These targets should be developed early in the design process and be aligned with the minimum 1 Pearl requirements. The development team will benefit substantially by understanding and targeting the required credits early in the process.
Example 1.2 Narrative summarizing vision, objectives, targets (partial)
Vision
“The office building will be a modern high-tech workspace that will avoid wasteful resource use”
1
Develop a vision for the building project. This should be a general, aspirational target that will give coherence to the design process.
Objectives
Provide sensors and controls to reduce unnecessary lighting
2 3
Establish objectives for achieving the vision. These should be more specific goals.
Targets (credits)
Establish specific and measurable targets for achieving the objectives and vision. These will form a framework for the design process.
“Reduce lighting loads per square meter 20% below a typical office building” (RE-R1 Minimum Energy Performance)
Solutions
4
Develop solutions for reaching the targets. Identifying practical, cost effective, integrated solutions will be the outcome of the design and development process.
Architect: Strategic window placement and shading Engineer: Automatic daylight-dimming of lights occupancy sensors and automatic shut-off when rooms are unoccupied
1.3 Plan & hold regular design workshops After a kick-off workshop and establishing the vision, objectives, and targets, it is important to continue holding multidisciplinary design workshops to foster creativity and collaboration. Workshops help ensure everyone is aware of important decisions throughout the development process.
Example 1.3a: Workshop documentation
Schedule regular multidisciplinary workshops at the outset of project planning. These should include the following topics, at minimum: • site and ecology • orientation and climatic response • energy, water • waste management • indoor comfort • sustainable materials specications. Additional workshops can also be scheduled on an asneeded basis.
Document the occurrence of meetings through submission of meeting minutes.

1.4 Develop an implementation strategy A strategy for implementing the sustainability goals of a building should be developed to ensure that sustainability targets established during design are met during construction and occupancy. This can be assisted through the selection of suitable design team members at project inception to fulfill the Clients requirements. Engage all members of the development team early in the process, including the contractor and commissioning agent (who will verify the performance of building systems). If possible, the contractor should be involved in the whole IDP process. Ensure that the specification documents contain the sustainability targets and solutions established during the IDP workshops. The requirements are to clearly stated as being mandatory and where alternative solutions provided these must meet or exceed the original intent to achieve compliance with all the mandatory Estidama credits. Ensure that the future developers and tenants will receive a fit-out design & construction guide. This will provide instructions on how to address sustainable design and construction in the tenant space.

2.0 Understand site context At the start of the design process, the project team should find ways to understand and optimize the relationship between the project site and its surroundings.
Management Strategy must be prepared to ensure the long term survival and management of the landscape and habitat areas.
A thorough understanding of the site’s natural and urban context will help inform an optimal site layout. This understanding will also support many design objectives, including:
The project team will then be able to move on to the next step in the process: planning the site layout.

improved outdoor thermal comfort; energy use reduction; water conservation; and ecological enhancement.
Natural systems, such as existing habitat and topography, and urban systems, such as nearby community facilities, can be examined in separate assessments or together. Ultimately all site information should be integrated to identify opportunities and constraints associated with building on a particular site. The project team should ensure that they adhere to the vision set out in Plan 2030. Any significant or valuable natural systems identified in the natural systems analysis should be adequately protected. If protection is not possible and a strong rationale is given for development, the adverse impacts of development on natural systems must be mitigated or compensated. A Natural Systems Design and

2.1 Consider plan Abu Dhabi 2030 From the beginning of the design process through to construction, the project team should design, procure, and make decisions based on the principles set out in Plan Abu Dhabi Vision documents developed by Abu Dhabi’s Urban Planning Council. The Urban Planning Council was established by Emiri decree in 2007 to introduce a planning culture and new strong guiding principles for future developments. The Vision documents represent sound foundations for development in the emirate and is an essential part of the planning process. Adherence to Plan Abu Dhabi 2030 is included as part of Estidama, but is also required as part of the Development Review process by the UPC and therefore is an integral part of the planning process. To satisfy the requirements of Estidama, Designers and Project Team members must consider one of three documents that relate to the location of their project: • Abu Dhabi City - Plan Abu Dhabi 2030
Related Credit: LBo-R1: Plan 2030
Plan Al Ain 2030
Western Region
Plan Al Ain 2030 is the central planning document for Al Ain. As an ancient oasis crossroads Al Ain represents cool respite and a rich cultural heritage for Emiratis. Al Ain is a special place and its development must reflect this; Plan Al Ain 2030 sets the scene for future development that respects history and culture while encouraging sustainable growth. The diagram below illustrates the major topics covered in Plan Al Ain 2030 and how they come together.
Plan Al Gharbia 2030 is the central planning document for Al Gharbia. It is designed to aid in moving Al Gharbia toward the future with managed, responsible growth. Respect for the environment, social health, cultural identity, and economic development all share equal status and provide the opportunity to leverage economic growth without sacrificing the cultural and historic significance of the region.

Zoom in on the Project Location
2.2 Assess natural systems At the beginning of the design process - and before site clearance takes place, undertake an assessment of the natural systems in the context of the project site: • the area of probable impact surrounding the project site; • sub-regional scale; and • regional scale. The assessment can be a combination of desk top studies and field surveys. As a minimum, a field survey, including a Phase I Habitat survey, or similar, must be completed for the project site itself. A desk top study or similar would suffice for the area of probable impact, sub-regional and regional analyses.
Example 2.2a: Site plan showing natural systems
Related Credit: NS-R1: Natural Systems Assessment
The natural system assessment should cover:
Topography, geology and soil conditions Topography, geology and soil conditions are important for understanding key view points, how building foundations should be constructed, how different areas will accommodate landscaping and how the site will drain both rainwater and irrigation.
Hydrology and groundwater Groundwater is a precious environmental resource. Groundwater conditions and any groundwater abstraction, hydrological conditions of the site should be identified to determine the drainage strategy and susceptibility of groundwater to pollution/contamination.
Prevailing Wind
Waste & contamination Any contamination on site by petrol, refuse, or other chemicals and materials that could be harmful to human health or the environment should be identified to determine the need for remediation. If previously unreported contamination is found or suspected, the site developers should contact the relevant environmental agency to determine further testing and remediation requirements.
Coastal conditions
Sun Path Undisturbed High Ground Mature Tree Planting Low-Lying Ponds Ancient Cliff In fill Sabkha Cemetery
The coastal environment requires careful management as highlighted in the 2030 Plan. Many coastal areas contain mangroves that are an important symbol for the city. Waterfront developments should consider a potential rise in sea level+ and adapt designs accordingly.
Archaeological features Appropriate desk studies and consultations with relevant government bodies such as Abu Dhabi Authority for Culture and Heritage (ADACH) should be carried out to determine the potential for archaeological features to be found on site. During the field survey any notable features should be
Microclimate Local site microclimate, including winds and shaded areas, should be evaluated to identify passive design features that can be incorporated into the design to improve thermal comfort. Abu Dhabi’s characteristic sun angles, diurnal temperature swings, and relative humidity should be considered. An east-west building orientation generally maximizes the opportunity for shading control.
Flora & fauna, priority species, habitats and ecosystems Though most proposed sites in Abu Dhabi will contain limited habitat, areas that contain priority habitats such as mangrove, sea grasses etc are particularly important to protect and preserve. Attention should be paid to identify ‘significant assets’ and ‘valuable assets’. ‘Significant assets’ in Abu Dhabi include intertidal mudflats, mangroves, vegetated sandy beaches, marine (seagrass, coral), wadis, sand sheets and low dunes, interdunal plains and high dunes, alluvial plains and jebels, or any other sensitve habitats identified. “Significant assets” also includes protected species determined to be critically endangered, vulnerable, threatened, near threatened or sensitive. ‘Valuable assets’ are features of ecological value, including healthy native trees or shrubs. In addition, the assessment should consider the wider region, identifying any internationally, nationally or locally protected areas and species. Refer to the Plant Information Database on the UPC website for species identification information.
The following items should be included in the Natural Systems Assessment Report:
• Narrative (describing all the natural systems on the site, the area of probable impact surrounding the project site, sub-regional and regional scale) • Maps (highlighting different natural systems and areas to be protected, enhanced and allocated for habitat creation/ restoration)
Maps and site photographs must clearly identify the extent of different habitats and other natural features. The assessment must be carried out by a suitably qualified environmental professional trained to complete such analysis and assessment.
• Site Photographs
Example 2.2b: Narrative Extracts • “Although sparsely vegetated, the proposed site includes two notable ecological assets, depicted in photos: a spiny-tailed lizard burrow and several ghaf trees.” • “The existing ghaf trees, as a native species, are valuable for both habitat and landscaping. They are preestablished, non-invasive and, as a drought-resistant, salt-tolerant species, will require less irrigation than other species.” • “The soil of most of the plot has been found to be sandy up to a depth of 35 cm with a more rocky substrate underneath. In the northwestern portion of the parcel, soil contains more sandy load, in part in relation to the presence of the trees.” • “The site-wide masterplan included an inspection of the site for potential contamination. As a previously unutilized location, no contamination has been
identified or suspected on this proposed site.” • “The microclimate generally corresponds to Abu Dhabi averages with some particularities, as follows: ° High midday sun with marginal overshadowing from adjacent developments to the south. ° High levels of solar radiation year-round ° Exposed on north and south sides, ° Warmer southern winds prevailing during day ° Cooler NW winds in mornings & E winds at night ° Site allows for optimized building orientation ° Existing trees on site provide shaded zones ° Adjacent properties can break-up wind regime and introduce turbulence”

identified in the Pearl Rating System. These are summarised in Table 2.3:
coastal conservation zone, must be protected, and 80% of valuable assets protected.
Where significant and valuable assets are present, a Natural Systems Protection, Mitigation and/or Compensation Strategy with supporting studies must be prepared by a suitably qualified ecological specialist.
If the Natural Systems Assessment clearly documents that the site has no significant or valuable natural assets, the site does not need protection or mitigation. Other credits will be achieved under the PBRS if the project provides landscaping that consists of native species and uses minimal water.
The ecological features of the site can either be protected or disturbance can be mitigated. Three strategies to do this are
All significant natural assets associated with a protected area, national park, a coastal park, ecological hotspot, or a
If part of the project›s natural systems strategy included mitigation or compensation, at least 70% of significant assets and 50% of valuable assets must be protected. If mitigation occurs on-site, new habitat areas must equal the area of the lost assets. If on-site mitigation is impractical and off-site compensation must be pursued, the new habitat area must be twice the area of assets lost.

During the design of outdoor areas, project teams should lay out buildings, roads, and public spaces on site to protect and celebrate the presence of on site ecological features. These features could form a theme for site-wide landscaping strategies. The natural systems strategy should outline any activities that may cause damage to sensitive areas during the operation and construction phases of the development. It should identify measures that have been designed into the scheme and those that will be implemented during the operation to protect these areas / species, for example, limited access to mangrove areas and boardwalks provided for pedestrians to minimise damage to mangrove roots. The protection strategy should include measures such as: • Design protection measures • Ensuring that work compounds, access tracks etc are not located in or adjacent to sensitive habitats • Establish temporary fencing around protected areas to restrict access • Undertake any works near protected areas in a manner so as to safeguard their integrity • Undertake works considering any critical seasons for protected species Some of these measures could be included in the Construction Environmental Management Plan if prepared as part of IDP-3. The Mitigation Strategy report should identify the areas to be protected and measures adopted to ensure their protection, as outlined in the Protection Strategy Report. It should identify the mitigation areas and justification for the appropriateness for mitigation including: • Area calculations • Identification of appropriate plant nurseries
• Continuous monitoring of success or failure of young plants • Management techniques to encourage establishment. This should be adapted following any failures. The Compensation Strategy report should demonstrate options considered for off site compensation and the selection criteria for the proposed compensation site. The report should include measures to ensure flora establishment as outlined in the mitigation strategy and protection measures as outlined in the protection strategy. Consideration should be given to the habitat lost on the proposed site and the potential to provide enhanced habitat of a similar type to the habitat lost. The author of this report should be a qualified ecologist who has experience in habitat establishment for those particular habitats, for example, mangrove specialist.
2.4 Manage natural systems A Natural Systems Design and Management Strategy is required to ensure the long-term survival and prosperity of ecological assets. The strategy must cover all landscaped areas and include the management of any on or off-site protected, mitigated or compensated natural asset areas. The strategy should promote soil protection and enhancement, low maintenance requirements and low demand for resources. The team should consider using only native species, and landscapes that do not require wasteful use of irrigation when developing the landscaping strategy and Natural Systems Design and Management Strategy. This will be rewarded with additional points under options PBRS credits. The Management Strategy should identify the seasons during which each activity will be carried out.
Soil protection Plant selection should suit existing soils onsite. Where soil enhancement is required this should be tailored to the existing soil type. Where soils is brought on site, this should be protected from erosion, pollution and increases in salinity. Paths should be provided to avoid pedestrian compaction of soil. Irrigation should consider the topography of the site and soil erosion.
Low maintenance requirements Landscaping should be a combination of hard and soft landscaping, and should minimise the application of fertilizers, pesticides and herbicides. Landscaping should promote low maintenance requirements.
Low demand for resources Plant selection should reflect the microclimate conditions of the area. Water efficient irrigation systems such as drip irrigation should be adopted to minimise water consumption.

2.5 Assess urban systems An urban systems assessment details the urban context around the project site, the type of neighbourhood the building will exist within, and how accessible and integrated the building will be.
Example 2.5a: Plan showing local urban systems
The analysis should be carried out at the start of the project, before site clearance, to inform project programming, neighbourhood connectivity and built form. The end-product of this analysis is the Urban Systems Assessment Report, and should include a narrative, maps, and site photos. Site plans or diagrams should be provided at the Local, Subregional, and Regional scales. The content of the plans provided should be tailored to the scale of the plan, i.e. local, sub-regional or regional. Where facilities are to be provided in the future, this should be indicated. Plans provided should document the following at a minimum:
1 2 3 4 5 6 7 8
Community facilities Public interest areas, such as public beaches, cultural or heritage landmarks Street patterns Public transit facilities, bicycle and pedestrian paths
Utility corridor Bike Path
Utility plots and corridors, such as electricity, gas, potable water and wastewater

2.6 Identify opportunities + constraints Contextual opportunities and constraints are important to identify to allow the development to take advantage of special site features and address site challenges effectively. Information obtained in the Natural Systems Assessment and in the Urban Systems Assessment informs the formation of a complete opportunities and constraints analysis. An example study is shown to the right, illustrating how Opportunities and constraints can be used to inform the design of a site. The opportunities and constraints of the proposed site will determine the areas that can be developed, the most appropriate type of development and issues that will need to be addressed during the design, for example, contamination and remediation strategies.

Local Traffic Route Spiney Tailed Lizard Burrows Protected Ghaf Trees
Key Performance Indicators (KPIs) should be prepared to guide the design of the development based on the results of the opportunities and constraints analysis. The KPI’s should be measurable targets and cover soil, flora, fauna, microclimate, topography, drainage, targets set to mitigate identified constraints and areas of site to be protected, maintained, created or restored. Examples include: • Percentage increase of protected species / priority habitats on site through habitat enhancement • Percentage of reuse of soils on site
Sun Path
3.0 Design outdoor spaces The impact of a building can be reduced significantly by decisions made early in the design process. The relative location of other buildings, windows, and outdoor areas ditectly impacts on the amount of energy, water and materials required to keep a building comfortable. The buildings orientation and massing has to be planned in relation to its urban and natural environment. Building should be designed to reduce internal heat gains and harness daylight so that their energy demand will be reduced. This can be achieved by using materials in the buildings envelope that comply with the minimum U values specified in credit RE-R1 and also by careful selection the glazing elements in the facade. When selecting building materials, the requirements of credit SM-R1 that forbids the use of chromated copper arsenate (CCA) treated timber and asbestos containing materials (ACM). Buildings can also contribute to improve pedestrian comfort by providing external shading and shielding pedestrians from prevailing hot winds hence contributing to the requirements specified in credit LBo-R3. Local weather data sets are available to analyse how the building elements will perform
and the effect the building will have in its surroundings. The buildings plot landscape should be designed to protect and link natural habitat around it. The building should also be adequately linked to the adjacent streets to facilitate pedestrian and vehicle movements. In particular, credit SMR3 requires to provide access to waste collection vehicles. Finally, the design of the building outdoor spaces should meet credit LBi-R2 requirements to designate smoke free zones around sensitive areas of the building but also to allocate dedicated external smoking areas.

3.1 Building layout The layout of the buildings on the plot has many implications later in the design process, especially with regard to energy performance and external shading. The design team should carefully consider the following:
Optimize natural light but minimise solar gains
1 2 3 4
Utilize external shading devices to reduce solar gain, whilst maintaining external views. For example by providing horizontal shading on South orientation and vertical shading on East and West orientations. Use shadows cast by surrounding buildings to provide shade and reduce solar gains. Place windows in shaded areas, recessed into the wall, or facing North to provide light to indoor spaces. Use rooflights sparingly as these significantly increase solar heat gains. Consider using sunpipes or solartubes instead.
Related Credits: LBo-R3: Outdoor Thermal Comfort Strategy RE-R1: Minimum Energy Performance
Harmonious integration with surroundings & pedestrian environments Cool breezes can reduce heat build up in external areas as well as freshen the air in externally accessible areas. Hot winds cause unpleasant and uncomfortable conditions building up heat in external areas, increasing heat load on the building and increasing pedestrian thermal discomfort.
1 2
Understand local wind climate, identifying orientation, timing and temperature of prevailing winds.
3
Use building form and position to best use cool breezes. This will help to reduce build-up of hot or stagnant areas at pedestrian level.
4 5
Use building form to shelter pedestrian areas from hot or high speed winds.
Consider position, form and orientation of nearby buildings to understand wind movement and how the external environment is affected.
Consider the use of external building features as well as building form and massing to minimize adverse impacts from wind on the public realm. Features to be considered include, but are not limited to: •
shading devices, e.g. brise-soleil, mashrabiya, etc.
•
overhangs
•
breaks in facade continuity
•
podiums
•
openings

3.2 Outdoor thermal comfort The building orientation in relation to local winds and sunpath as well as the influence of surrounding buildings and other landscape elements should be considered to provide an adequate outdoor space that improves the building’s exterior microclimate and achieves adequate pedestrian comfort.
The following example shows different strategies of how the required levels of shading can be achieved using adequate building layouts, natural elements or some additional construction elements.
Example 3.2a
In particular for shading, it is required to check that the shading percentage required by credit LBo-R3 is achieved on the equinox (21st of March) and the summer solstice (June 21st ) at 1.00pm over the following elements: •
Exterior Surface Parking with more than 10 spaces, including parking on exposed roof car parks
•
Public Open Spaces, including privately owned
•
Pedestrian walkways
•
Cycle tracks
•
Playgrounds
The checks can be done using sun altitude and azimuth data (For Abu Dhabi, the summer solstice alt = 81.4º, azi =-94.6º and for the spring equinox alt = 64.2º, azi = -161.6º) or an appropriate software such as 3D CAD software, e.g. Ecotect, or free 3D tools, such as Sketch up. Shading can be provided by mature trees or by structures, such as canopies. If structural elements are used, their outer surfaces must have a minimum Solar Reflectance Index (SRI) of 29. The SRI is a measure of the roofs ability to reflect solar heat, and the higher it is, the better the surface is a reflecting heat. High SRI can be achieved with light or reflective materials and/or finishes, e.g. some concretes, light aluminum cladding. The guidelines in the UPC Urban Street Design manual can be used for designing the outdoor spaces around the building. The manual can be downloaded from http://www.upc.gov.ae/guidelines/urban-street-designmanual.aspx.

3.3 External waste and recycling storage The central waste and recycling storage room is typically located in the building’s ground floor or basement and should be easily accessible from street level by collection vehicles. It is typically air conditioned, enclosed and located near loading docks or bays and has doors at least 1.8 m wide to facilitate material movement and pick up as shown in examples 3.3a and 3.3b. The room must be sized to allow for the storage and movement of waste containers.
Example 3.3b
To reduce the volume of waste and recyclables, and associated space requirements, compactors or balers are typically used. Particular attention has to be paid to turning radii of collection vehicles and vertical and horizontal clearances required for vehicle manoeuvring. Vehicle reversing should be avoided if possible. When compactors are deployed in basements, a minimum local clearance of typically 5.5 m is required as shown in example 3.3c. Related Credits •

3.4 External building materials As the building and plot areas take shape, it is important that the appropriate materials are selected for external structures and facade. There are several requirements to consider when specifying these materials.
U- values The materials that comprise the structure and facade of the building will form its thermal envelope – the main barrier to external heat and solar energy. Keeping the occupied space cool and comfortable is an easier task with a high performance envelope. The U-value is a measure of how much heat passes through a given material (i.e. how much insulation the material provides). The project team should specify and build the building envelope to achieve the lowest possible U values and in any case achieve the minimum U-value requirements outlined in RE-R1 which are defined by ASHRAE Standard 90.1-2007, Section 5. For the UAE the relevant climate zone is zone 1. The following practices can be used to achieve the required values: • Provide insulation between the earth and concrete oor slab to reduce heat from the ground warming the rooms. • Insulate above the roof slab and apply an external nish in a light color to reflect solar heat. • Include sufcient insulation in the building walls. In addition to the basic U-value heat transfer reduction the following factors can also benefit the energy and internal environment:
Thermal mass Place concrete elements adjacent to the occupied spaces, to buffer thermal energy and provide a cool surface feel for the occupant.
Vapor barrier Provide a barrier to restrict ingress of moisture through the building walls, floor and roof. This is a critical protective consideration given the high humidity in the coastal area of the UAE.
Exterior Surface finishes Use light colors to reflect sunlight and reduce absorption of solar energy. This will reduce heat build up and gain through the walls and roof.
Glazing design Glazing design is important for overall building energy usage, because windows bring light and heat into occupied spaces. Credit RE-R1 details the requirements for both windows insulation, e.g. U values, and radiative heat gain, e.g. solar heat gain coefcient (SHGC). The U value requirements will generally require double glazing coatings while the SHGC requirements can be achieved with tinted glass or reflective factory applied coatings. These factors can be specified to the glazing manufacturers; a wide range of suitable, compliant products are available within the UAE.

3.5 Smoke free zones & dedicated external smoking areas There are several requirements that need to be fulfilled to comply with LBi-R2 Smoking Control which include: •
Establish smoke free zones around sensitive areas of the building;
•
Provide dedicated external smoking areas with associated facilities; and
•
Train security staff to enforce smoking policy.
Smoke Free Zones The design team must first identify the locations of entrances, openable windows and air intakes of the project building, but also of any adjacent existing building that may be similarly affected. Each of these areas will require protection by establishing smoke free zones within which people must not be allowed to smoke at any time. Care should be taken to accommodate the horizontal width of each item, for example an air intake, as this can be substantial and will determine the extent of the smoke free zone. Example 3.6 is an example of how project teams should establish the extent of smoke free zones by plotting loci (shown in red) to the extent required by the Pearl Building Rating System. These plans or figures can be used to communicate the extent of the smoke free zone when training security staff.
devices to meet this requirement. For example, locations at grade near to unrestricted high pedestrian traffic public right of ways should consider wall mounted devices whereas campus type facilities with restricted public access can install free standing devices. In any event the external smoking area must not be located directly within public or high use pedestrian thoroughfares. Posters (for example wall, board or bench mounted) or other suitable media, such as through leaflet stands must also be provided listing the negative health impacts of smoking and provide details on where to seek assistance for those aiming to stop smoking.

People who own or rent apartments within a residential building can smoke within their apartments, therefore dedicated external smoking areas may not always be needed. Where such facilities are to be included, design teams must follow the guidance detailed above. Related Credits: •
LBo-R3: Outdoor Thermal Comfort Strategy
Dedicated External Smoking Areas After plotting the smoke free zones, the design team can look to establish suitable locations for dedicated external smoking areas. Care must be taken not to encroach upon the air intakes, entrances or openings associated with any adjacent building. Where space is constrained, typically in a dense urban setting, sharing smoking zones with adjacent buildings can be considered. All dedicated external smoking areas must have appropriate and suitable facilities for collecting ash and cigarette ends. Consider the nature of the location when deciding upon
Example 3.5: Smoke free and smoking zones
3.6 Hazardous materials It is also important to ensure that selected materials do not contain hazardous components excluded by credit SM-R1. The design team should be aware of these requirements while designing exterior spaces.
Example 3.6a: Extract from specifications
The prohibition of hazardous materials should also be written into the project specification documents during the design stage and followed by the contractor during the construction stage.
In compliance with the Pearl Building Rating System for Estidama, credit SM-R1 Hazardous Materials Elimination, the following materials shall not be used:
1
Specify that materials, including walls, insulation, and interior materials, will not contain asbestos and that all asbestos containing materials have been removed from refurbished buildings.
1. Asbestos Containing Materials (ACM)
2
Specify that wood materials exposed to the outside and within human reach – such as shading structures, playgrounds, and decking – will not be treated with chromated copper arsenate (CCA).
2. Chromated copper arsenate (CCA)-treated timber, where timber is used for external structures subject to frequent and intimate contact. These materials include, but are not limited to, shading devices, playground equipment and handrails”

4.0 Design indoor spaces There are many factors to consider when planning the layout of spaces inside a building. These factors relate to: • energy consumption • visual and thermal comfort
Credit LBi-R2 requires residential units or apartments to be appropriately sealed to eliminate or minimize exposure of building occupants to the harmful effects of tobacco smoke from neighbouring apartments. This should be done with adequate seals and weather-stripping.
• ventilation • daylight
useful resources:
• materials emissions
•
Some factors may conflict with others, for example, a space designed for excellent day lighting may be detrimental to energy consumption as a result of poor facade decisions.
•
Occupant comfort is an important consideration, this includes understanding visual and thermal comfort and as well as ensuring sufficient fresh air provision. The project team should also look to reduce the source of material emissions through low VOC products.
• •
It is important, therefore, to develop a project with the right blend of carefully considered solutions.
Approach The layout and position of internal spaces within the building to suit daylight and ventilation have to be considered at this stage as per credit RE-R1. It is also necessary to specify glazing correctly to ensure optimal trade-off between light ingress and solar transmission. This design should be done bearing in mind credit LBi-R1, which requires that all spaces must be ventilated according to the requirements of the ASHRAE 62.1 2007, or local code, whichever is more stringent. The consideration of ventilation strategy is an important factor for both RE-R1 and LBi-R1 credits as they are both affected by natural and mechanical ventilation system performance. As in previous steps, materials forbidden by credit SM-R1 (asbestos and chromated copper arsenate treated wood) should not be specified for indoor spaces. All decisions affecting the design of the building indoor spaces must be

4.2 Smoking Control Smoking within a building is only permitted for occupants within ‘residential units’, or apartments. No smoking is permitted within any and all common areas of the building including car parks. To comply with the requirements, each residential unit must be sealed with impermeable deck to deck partitions along the whole perimeter of the unit (walls) and vertically between units (ceilings and floors). All penetrations within these walls, including those for wiring, pipework, ductwork, switches, electrical outlets, recessed fixtures and risers must be fully and appropriately sealed. Examples of sealing processes include caulking or spray foam application. Whilst the designer should identify suitable materials for sealing gaps, contractors must ensure that the sealing of gaps is carried out adequately. All doors leading from a residential unit to a common area, such as a corridor, or between residential units must be weather-stripped. To achieve effective weather-stripping, the architect must design and the contractor must ensure that gaps around doors are not so large that weather stripping cannot provide an adequate seal.

4.3 Internal waste and recycling storage Waste and recyclables generated by activities undertaken in a building is known as operational waste. The amount of this material generated depends on the building use, (e.g. office, residential) and should be managed proficiently. This can be achieved by following the “Reduce, Reuse, Recycle” principle to minimise economic costs and environmental impacts. A building-level management strategy for waste and recyclables should be created by the design team and implemented by the facilities management team to achieve the minimum requirements of the Pearl Building Rating System. The strategy must:

Waste and recyclables generated in the building should be stored on each building floor before being taken to a central storage facility for the whole building. From there it will be collected for transport to the appropriate treatment or disposal facility. The floor transfer rooms should be clearly indicated, well ventilated, easy to clean and located near service lifts or waste chutes, in common areas of the buildings but separated from them. Each room should be sized according to:

5.0 Design building systems The lighting, shading and ventilation strategies established early in the design process will reduce the requirements for building systems. Careful detailing of systems to provide cool, comfortable and efficient performing indoor spaces can further reduce the buildings environmental impact.
Approach
Materials and Waste
For credit LBi-R1, the building must comply with ventilation requirements set out in ASHRAE Standard 62.1-2007, or local code, whichever is more stringent.
SM-R3 requires waste generated in the building to be stored on each building floor before being taken to a central waste storage for the whole building from where it will be collected to the appropriate treatment or disposal facility. Credit IDP-R1 requires decisions regarding the design of MEP and waste to be agreed on in integrated development workshops.
Energy The design of the building HVAC and lighting systems is driven by the requirements outlined in ASHRAE Standard 90.1- 2007. Compliance with RE-R1 is achieved by a 12% improvement in Proposed Design Energy Performance when compared with the Baseline Design Energy Performance. This improvement is demonstrated through dynamic simulation modelling to simulate energy performance as outlined by the Performance Rating Methodology in Appendix G of ASHRAE 90.1-2007. Credit RE-R2 requires energy submetering, whereby installed meters are to be clearly labeled and provided in easily accessible locations. They must measure, as a minimum, 90% of the estimated annual energy consumptions of each fuel type (electricity, gas, etc) for all energy end use categories, in both Landlord and Tenant areas. Metering is also required for all onsite energy generating systems and large plant items.
Water Efficient water fixtures and metering are covered by credits PW-R1 and PW-R2. Estidama requires specific flows rates for water fixtures, fittings, and appliances. As with energy meters, water meters must be easily accessible and clearly labeled, to sub-meter the building’s external water use. These must have a pulsed output and be capable of remote monitoring.
Credit RE-R3 specifies that only refrigerants and fire suppression systems with an ozone depletion potential (ODP) of zero can be used for any purpose onsite. useful resources •

5.1 Energy system Air conditioning and mechanical ventilation Although the cooling requirements of a building will be reduced by minimizing heat gain through windows and other external surfaces, energy must also be used to condition spaces in Abu Dhabi’s climate. Efficient system performance is therefore a critical factor in achieving reductions in energy usage. For most buildings the performance of the air-conditioning system is based upon: •
The efficiency of energy conversion from electricity to cooling, typically provided by localized units, central chillers or district cooling
•
The effectiveness of the fans providing air to the spaces, both fresh and recirculated air
•
The selection of appropriate sensors and controls for various system elements in different zones
•
The response of the system to variation in thermal loads and occupant requirements
•
The inclusion of energy recovery, performance modulation and other efficiency measures.
There are requirements for all aspects of system performance outlined by ASHRAE Standard 90.1-2007. However in order to achieve the target performance required by credit RE-R1 it will be necessary to demonstrate improvement beyond the levels defined in Standard 90.12007.
Lighting Good lighting design can reduce energy usage internally and externally. Internal lighting energy is restricted on a basis of power used per unit area. Power allowance is based on the building type or the space type classification as outlined in Standard 90.1-2007. Example performance for the building type classification is shown in table 5.1.
In addition to reducing the energy consumed by lighting systems, good use of controls and sensors can increase energy savings and reduce the cooling load required. Examples of lighting controls include: • Occupancy sensors • Daylight sensors • Dimmable controls • Programmable time controls External lighting is also restricted on the basis of power use, either per unit area or per linear meter as defined by Standard 90.1-2007 for various functions. Furthermore external lighting should be controlled to ensure that it is not operational during daylight hours, which will reduce energy wastage.
Renewables The use of onsite renewable energy sources to contribute towards the building load is encouraged. Renewable technologies should be designed to integrate with proposed building design, HVAC systems and lighting.

5.3 Refrigerant Refrigerant Many of the refrigerants currently used in air conditioning systems cause damage to the ozone layer. The ozone layer protects the earth’s surface from damaging radiation. This environmental impact can be reduced by the appropriate selection of refrigerants and fire suppression systems with a zero ozone depletion potential (ODP). RE-R3 requires that refrigerants and gaseous fire suppression systems installed within the plot have a zero ozone depletion potential. This would require avoiding refrigerants such as HCFC-22, which even though will not be banned until 2015 within the UAE, it is required that it is not used due to it still having an ODP. Refrigerants with an ODP of zero are required such as HFC-134a.

5.4 Water fixtures Optimize interior water consumption Interior water consumption within a building is attributed to fixtures and appliances such as taps, toilets, washing machines etc. Large water savings can be made by using low flow fixtures and high efficiency appliances. PW-R1 sets a minimum standard for fixture flow rates and appliance efficiencies. These flow rates are as follows:

To comply with PW-R1, a project must demonstrate that the proposed buildings interior potable water consumption is less than or equal to the baseline building interior potable water consumption based on the flow rates detailed within the adjacent table. This must be demonstrated by utilizing the PBRS Water Calculator v1.1 available from www. estidama.org. The calculator allows the project to trade between flow rates so that the efficiency of certain fixtures/appliances may be relaxed only if others are improved. This ensures that the overall proposed building interior potable water consumption is less than or equal to the baseline. The next few pages contain snapshots of the ‘PBRS Water Calculator v1.1. This will help the design team select appropriate fixtures and demonstrate compliance with the Estidama requirements.

The following must be seperately submetered where present: • Irrigation Systems • Heat Rejection • Swimming Pools • Water Features The meters are also required to have data logging capability and be connected to a central monitoring system so that the exterior water consumption may be recorded. This, and a better understanding of both interior and exterior water use will help determine areas of high water consumption, identify leaks quickly, and pursue opportunities to save water.

5.6 Legionella Legionnaires disease is a potentially fatal form of pneumonia which principally affects those who are susceptible due to age, illness, immunosuppression, smoking etc. HSE Approved Code of Practice (ACoP) L8: Legionnaires‘ Disease — The Control of Legionella Bacteria in Water Systems applies to plant and water systems which may present a particular risk potential by releasing a spray or aerosol during operation or when being maintained. Relevant water based systems include but are not limited to: • Water systems incorporating a cooling tower or an evaporative condenser. • Hot and cold water systems. • Other plant and systems containing water which is likely to exceed 20ºC and which may release a spray or aerosol during operation OR during maintenance. • Humidiers. • Air washers. • Spa baths and Pools. • Car / bus washes. • Wet scrubbers. • Fountains and Water features (Indoor and Outdoor). • Sprinkler and hose reel systems.
Roles and responsibilities The design engineers should support the Client in developing guidance including design and operational intent. HSE ACoP L8 requires the owner to appoint an operations manager who should ensure that all responsibilities are clearly defined and formally allocated. The owner is also responsible to ensure that control procedures are carried out to the standard required to prevent the growth of
Related Credits: LBi-R3: Legionella Prevention
Legionella Management Plan At all stages adequate measures should be implemented to minimise the risk of contamination. A Legionella Management Plan must be developed at the outset of the project and should address the following: 1. Identify and assess the risk in the design and operation of the building to assess the level of risk associated with water systems. If the risks are insignificant, no further action needs be taken, other than periodical reassessment in case anything changes in the system. 2. Manage the risk: management responsibilities, training and competence. If a risk is identified, proper controls must be introduced and documented within the Legionella Management Plan. Risks can be controlled by careful planning, management policy, competent staff and adherence to proper control strategies. 3. Prevent or control the risk from exposure to legionella bacteria. Consideration should be given to: • Ensure that the release of water spray is properly controlled. • Keep the system and the water in it clean. • Avoid conditions that favour the growth of legionella and other micro-organisms, water stagnation and materials encouraging growth. •Treat water to either kill legionella (and other micro-organisms), limit their ability to grow or biocidal treatment if applicable • Continually monitor all water where sources of legionella could occur. • Easy access for inspection, draining, dismantling and cleaning to all systems. 4. Record keeping of maintenance and documentation. Records need to be kept of the scheme and who is responsible for managing that scheme, these should also be kept with the results of the routine monitoring. 5.Ensure that information from manufacturers, importers,

6.0 Build building Once all the design has been completed, the process of constructing the building will start. This step covers the construction process from the potential demolition of existing structures to the completion of a new building. During this process, it will be necessary to maintain communication between the members of the design team, contractors, and developers, to ensure that the building is built to the correct design specifications. This will be facilitated by the IDP process and the implementation strategy agreed at the beginning of the design process.
Approach Estidama credit SM-R2 requires that 30% of the demolition and construction waste be salvaged or recycled by weight. This means the contractor needs to prepare a construction and demolition waste management plan before demolition begins. This plan is to be supported by the Building Waste Calculator that is available from the Estidama website. During construction, documents will need to be collected by a designated responsible person from the contractor who will work with the PQP to confirm the target has been achieved. Similarly, compliance with credit RE-R1 requires that good quality materials performing according to design specifications are used and that good construction practices are followed to ensure the fabric and system performance levels modeled are actually achieved. Credit SM-R1 requires guaranteeing that hazardous materials do not make their way into the project. There can be no asbestos or exposed wood treated with chromated copper arsentate.

6.1 Construction waste management Before starting any demolition or construction, it is necessary to develop a construction and demolition (C&D) waste management plan. This should incorporate:
1 2
Estimates of waste generation. The Building Waste Calculator will help to estimate the type and amount of waste expected for the project. This can be downloaded from the Estidama website. A destination for each waste type leaving the site. For example, specify that aggregates will be transported to the municipal C&D recycling facility, or that fit-out leftovers will be disposed to landfill.
3
Identification of materials to be salvaged or recycled. At least 30% of the estimated waste generation by weight has to be salvaged or recycled.
4
A location for storing waste on-site during construction. This should be conveniently located near the area where construction materials are delivered and has to be large enough to allow for separating at least aggregates and other waste streams.
An example of the above is shown here. These elements should be updated with information compiled during construction.

7.0 Verify performance Finishing construction is not quite the last step in an Estidama project. Key to ensuring sustainability is to verify the building will perform according to the design specifications. The performance of the structure and building systems should be evaluated, and occupants should be informed how to operate and maintain the building for best results.
Approach Credit IDP-R3 requires a Competent Professional to verify the building performs as designed to protect occupant health and provide comfort and ongoing building efficiency. Credit IDP-R2 requires all the Integrated Development Strategy created as part of the IDP-R1credit is clearly communicated using a tenant fit-out design and construction guide. This tenant fit out guide provides essential technical information such as design requirements, materials for the fit out design and construction and submittal for Landlord approval to ensure that compliance with the requirements will be checked by the developer. The envelope and systems should comply with the requirements of credit RE-R1. Information collected from the energy and water submeters required by credits RE-R2 and PW-R2 credits can be used to ensure optimum operation. Although credit IDP-R3 is completed after construction, it should be started earlier in the design process. Some systems need to be tested before installation. Note that the person who conducts the verification can be from a company involved in the design process, but the individual who verifies cannot be directly involved in the project for any other purpose.
