7 About Estidama & the Pearl Villa Rating System

8 Estidama and the PVRS What is Estidama? Estidama means sustainability in Arabic and is an initiative developed to achieve the late Sheikh Zayed bin Sultan Al Nahyan s dream to guide Abu Dhabi as a more sustainable Emirate. It establishes directives and recommendations for all types of building projects (including Villas) to ensure that they are designed to be resource efficient and comfortable to inhabit. Estidama covers multiple facettes of the Emirate s development: urban design, environmental health and safety, building development, zoning and planning. The mission is to preserve our cultural, economic, social and environmental resources for future generations while improving the lives of the current citizens of Abu Dhabi. What is the PVRS? A central initiative of the Estidama program is the Pearl Rating System (PRS), a set of sustainable building standards specific to Abu Dhabi. The PRS suite addresses three types of developments: Villas, Buildings and Communities. In May 2010, the Abu Dhabi Executive Council mandated that all new projects comply with the Pearl Rating System. As of September 2010, all new developments were required to achieve at least a 1 Pearl Rating. This means that every project reviewed by the Abu Dhabi Urban Planning Council (UPC) or requires a building permit from a Municipality will have to achieve required credits. environmental estidama economic cultural social

9 The Pearl Villa Rating System (PVRS) implements Estidama by specifically addressing how Villas are designed and constructed. It contains a series of credits, some of which are required and some that are optional. Villas that achieve the required credits are compliant at a 1 Pearl level. Villas that achieve the required credits plus 30 additional points are compliant at the 2 Pearl level. The highest distinction is 5 Pearl level, for achieving a total of at least 70 additional points. The PVRS measures and rewards the development of a Villa at two key stages: design and construction. Project teams must produce an application, to be reviewed for compliance by the relevant municipality, at both stages. The Estidama process is linked to the municipal permitting process, which also follows two key stages: Building Permit Application and the Application for Certificate of Completion. The PVRS outlines performance criteria under the following categories: Integrated Development Process: Encouraging crossdisciplinary teamwork to deliver environmental and quality management Natural Systems: Conserving, preserving and restoring critical natural environments and habitats Livable Villas: Ensuring quality of outdoor and indoor spaces Precious Water: Reducing water demand and encouraging alternative water sources Resourceful Energy: Targeting energy conservation through passive design measures, energy efficiency and renewable sources Stewarding Materials: Ensuring consideration of the whole-of-life cycle when specifying and disposing of materials Innovating Practice: Encouraging innovation and cultural expression in building design and construction to facilitate market and industry transformation. To assist with implementation, a series of guides, that include tools and resources, have been created to summarise the submittal processes, calculations and product selection.

10 Estidama and the PVRS Why do we need Estidama and PVRS? Abu Dhabi is evolving and you play a significant part in its evolution. If we continue to build and consume the way we are now, economic prosperity, quality of life, cultural richness, social integrity and environmental systems will decline. This is why we need Estidama. Vast resources are required to generate and sustain this growth. Metal, concrete, glass, wood and stone, all of which are expensive to produce and require large amounts of energy to create, assemble and transport. Demand for water will also continue to increase. Estidama is a system that promotes sustainable development, encourages us all to think differently about how we design, build, consume resources and influences the choices we make all to reach a more sustainable and comfortable standard of living. Local Challenges Abu Dhabi receives just 100mm of rainfall per year. With minimal rainfall and limited groundwater resources, Abu Dhabi, out of necessity, obtains much of its drinking water from the sea through the desalination process. This process requires large amounts of energy and results in salt being pumped back into the sea. This disturbs the delicate ecology of the Arabian Gulf which is a key resource for food. How we use this water is fundamentally important. The region has one of the highest water consumption rates per person in the world. Abu Dhabi also has extremely high temperatures which regularly exceed 40 C. Without cooling the air, these temperatures would be unbearable and could greatly impact our productivity. Large amounts of energy are currently required for lighting, appliances and air conditioning our homes. Implementing Estidama requirements will help conserve energy by ensuring they consume less to meet the daily needs of residents.

11 What are the Benefits? Estidamahas many benefits for Abu Dhabi. These include: Environment Reduce the demand for materials and consumption of energy and water. Protect, enhance and restore fragile ecosystems in the region. Reduce ground, air and water pollution to protect our health and well-being along with that of the environment. Develop a proactive response to climate change through reduction of greenhouse gas emissions. Economic Increase returns on investment for Pearl Rated developments. Reduce operational and maintenance costs. Improve quality of life and enhance productivity. Improve tenant retention and higher rental yields. Social Create cohesive neighbourhoods with mosques, schools, clinics and shops within each community. Encourage sustainability on all scales, such as community recycling, efficient use of landscaping and public transport. Raise awareness and promote sustainable development and living. Cultural Revive Abu Dhabi s tradition of achieving maximum benefit from minimal resources. Maintain Abu Dhabi s unique identity and cultural heritage.

14 What Makes a Pearl Villa? The Estidama Pearl Villa program drives the overall Villa design to enhance the quality of spaces created, ensure efficient use of natural resources and minimise negative environmental impacts. This is achieved by: 1. Promoting cross-disciplinary teamwork which encourages a new design approach with an emphasis on our consumption, the way we build, the way we live and the choices we make. 2. Setting performance criteria and minimum targets which relate to natural systems, energy, water, materials, waste and indoor and outdoor quality. Business as Usual Leaky envelope with low levels of insulation Inefficient systems and appliances Wasteful water fixtures Poor indoor air quality and ventilation Ineffective and untidy waste management area Water-intensive landscaping favouring exotic species Hazardous and toxic materials, and off-gasing Estidama 1 Pearl Estidama PVRS Performance Targets Beyond 1 Pearl Air-tight envelope with good thermal performance Energy and water-efficient systems and appliances Low-flow water fixtures Comfortable indoors that can be naturally ventilated Effective and tidy waste management area Landscaping promoting native low-water consuming species Figure 3: Estidama PVRS Performance Targets

15 How does Estidama Measure Performance? The PVRS includes credits that set performance criteria and targets related to all seven categories of Estidama. These include: Enable natural ventilation through the provision of openable windows in all occupied spaces and size mechanical ventilation appropriately IDP - Integrated Development Process NS - Natural Systems LV - Livable Villas PW - Precious Water RE - Resourceful Energy SM - Stewarding Materials IP - Innovating Practice The mandatory criteria set for the 1 Pearl rating level are shown in Figure 4. Protect important natural assets identified on site such as Ghaf trees and design your villa in harmony with the natural elements Natural Systems Livable Villa Integrated Design Process Precious Water Install low-flow water fixtures and fitting and flow regulation systems; choose water efficient appliance and meter outdoor water usage This category gives designs an opportunity to showcase innovation in response to cultural, regional and environmental opportunities. Innovating Practice To encourage cross-disciplinary teamwork to deliver environmental and quality management Stewarding Materials Resourceful Energy Build airtight, thermally insulated walls, floor and roof; use energy-efficient, non-polluting AC units, lights and appliances and install a solar hotwater system Figure 4: Estidama PVRS Categories Avoid the use of hazardous materials such as asbestos and CCA-treated timber; recycle construction waste and provide a waste strong facility in your villa

16 How to ensure compliance? A Pearl Villa follows the same key design and construction stages as a conventional Villa. The introduction of the 1 Pearl performance criteria requires Consultants and Contractors to consider a number of basic sustainability issues. Space Planning Facade Design System detailing & Sizing Material Selection Material Procurememt Construction The Consultant must preserve valuable fauna and flora species (e.g. Ghaf tree) The Consultant is encouraged to shape building form to respond to the site s natural characteristics (solar orientation, exposure to wind, topography and hydrology) The Consultant must accommodate an external waste room designed to meet access, sizing, security and hygiene criteria set in the PVRS. The Consultant must size windows and distribute glazing in a way to balance: (1) access to daylight, (2) provision of ventilation and (3) reduction of solar heat gain. The Ventilation Calculator can be used to show compliance. The Consultant must detail the sections of walls, roof(s), exposed floor(s) to meet the thermal performance (u-value) criteria in the PVRS. Use sections from the Estidama Robust Details Catalogue or test your proposed sections using the U-Value Calculator. The Consultant must size mechanical ventilation to meet the flow rate criteria in the PVRS. The Ventilation Calculator can be used to show compliance. The Consultant must design artificial lighting to meet the minimum lighting densities (watt per m2) criteria in the PVRS. The Consultant must select building mateirlas and systems that can significantly reduce Energy and Water use in the Villa: Insulation products, Air Conditionning Systems, Windows, Water fixtures, and Solar Hotwater Systems. Select pre-confirmed products from the Estidama Techncially Compliant Materials database or use the appropriate calculators (U-Value Calculaor, Water Calculator) and undertake your own product research to show compliance The Contractor must procure products and systems in compliance with the drawings and specifications and design. When submitting alternatives, select pre-confirmed products from the Estidama Techncially Compliant Materials database or use the appropriate calculators (U-Value Calculaor, Water Calculator) and undertake your own product research to show compliance The Contractor must preserve valuable fauna and flora species (e.g. Ghaf tree) The Contractor must not use any hazardous materials such as asbestos and CCA-treated timber The Contractor must recycle construction and demolition waste and divert a minimum of 30% of waste by weight or volume- from landfill. The Consutant and Contractor must jointly verify that the integity of envelope and systems installed after installation Figure 5: Estidama Pearl Villa development

17 How do I select products? During product selection, Consultants and Contractors must consider many aspects of the design: Size Technical performance Quality Cost Aesthetic Sustainability performance Sustainability performance is principally addressed in Estidama. Products are evaluated based on their resource usage and environmental impacts. In Estidama, there are two pathways to product selection: 1. The Simplified Villa Product Selection Pathway, which requires products and systems referenced in the Estidama Villa Product Database and the Estidama Villa Construction Detail Suite. 2. The Conventional Villa Product Selection Pathway, which allows more flexibility and requires Consultants and Contractors to undertake product research and perform calculations using the provided Estidama Calculators. Further details can be found in the Pearl Villa Consultant Guide. The PVRS and associated Tools & Resources help Consultants and Contractors with product selection. The quality and integrity of these selections are the ultimate responsibility of the Consultant and Contractor. About the Simplified Villa Product Selection Pathway Based on preliminary implementation feedback received from key stakeholders, the UPC has created a Simplified Villa Product Selection Pathway for Consultants and Contractors. This pathway helps simplify the product selection process and accelerate application processing. The Simplified Villa Product Selection Pathway process relies on two items: 1. A suite of typical wall, roof and floor construction details referenced in the Estidama Villa Construction Detail Suite (EVCDS) 2. The Estidama Villa Product Database (EVPD) which reference the following classes of products: Air Conditioning Systems Water Fixtures (taps, showers, toilets and bidets) Windows Solar Hot Water Systems Insulation Products and Insulation Systems for Walls, Roofs and Floors Further information is available in the Tools & Resources section of this document and on the Estidama website: ( Figure 6: Flow Chart of Product Selection

18 Identify local suppliers Estidama workshop Advise Tech Criteria Suppliers Submit Product Data UPC compiles Estidama List Figure 7: Approach to development of EVPD How was the Estidama Villa Product Database (EVPD) created? From Municipality and Consultant feedback, several Supplier groups have recently participated in workshops regarding their products for Estidama technical compliance. Data has subsequently been submitted to the UPC for review prior to inclusion in the database. A summary of the approach to the development of the EVPD is provided in Figure 7. The database is open to all suppliers and manufacturers subject to meeting Estidama criteria. Please note, this does not mean products are certified by the UPC, it only means that aspects of their technical performance have been deemed to be Estidama technically compliant. How to use the Simplified Villa Product Selection Pathway during submission In order to prove compliance with the minimum 1 Pearl requirements, Consultants and Contractors are required to demonstrate that materials and systems used on the project meet the criteria set in the PVRS. Typically, project teams are required to perform calculations and supply manufacturer and testing information in order to prove compliance (as per the Conventional Pathway). With the Simplified Villa Product Selection Pathway, the only document required is a simple checklist listing the products used and confirming that they are listed on the EVPD. Benefits of the Simplified Pathway Benefits to Owners: Easy product comparison - performance, cost, warranties Competitive costs (no overpricing) Quicker application processing Benefits to Consultants and Contractors Pre-confirmed products and systems save time No additional documentation required to confirm compliance. Benefits to Suppliers Competitive advantage Greater market success.

Consider the impact of your Villa s interior layout as it relates to views and daylight. And make sure your Villa does not use hazardous materials. Influence Product Selection Use products listed in the Estidama Villa Product Database. This will ensure products and materials selected for your Villa are compliant and accelerate the permitting process. Influence Construction Best Practices Ensure that the Contractor recycles waste onsite and keeps the site tidy. Design to meet 1 Pearl Requirements Consultants must follow the technical criteria included in the PVRS, which balances performance criteria with optimal design. Prepare Estidama Design Application Consultants must follow the permitting procedure set by the relevant Municipality. The Estidama Assessors provide Consultants with Checklists and Credit Submission Templates for the application. Communication with Contractors Consultants must handover all relevant design documentation to the Contractor highlighting Estidama compliance. Supervise the Contractor Implementation The Consultant can ensure that the appointed Contractor is meeting the 1 Pearl requirements on site and is maintaining submission information within the Villa Contractor Toolkit. Build to meet 1 Pearl Requirements Contractors must follow the design documentation provided by the Consultant and ensure the technical criteria included in the PVRS are met. Prepare Construction Application Contractors must follow the permitting procedureof the Municipality. The Estidama Assessors provide Contractors with Checklists and Credit Submission Templates to assist them in the preparation of the application. Verify the Building Performance Verify all systems and the villa envelope are built to meet the design intent and comply with the 1 Pearl requirements. Provide an Occupant Handbook The Contractor must issue an Occupant Handbook to the Owner to highlight the key sustainability features of the villa and inform them about maintenance and operational requirements. Get products listed on the EVPD All product suppliers and manufacturers can apply to be on the EVPD database. They will be required to attend a workshop at the UPC and submit appropriate documentation on their products to demonstrate compliance. If you would like to be featured on the EVPD, ensure that your products and materials comply with Estidama technical requirements by completing the Estidama tools (e.g. Water or U-value Calculator).

21 Villa Owner As the Owner, you play an important role in ensuring that your Villa achieves a 1 Pearl rating. You can influence decisions made about your Villa and guide your team in its design and product selection. Your Villa team should help in ensuring all Estidama requirements are met. You will need to employ a Design Consultant early in your process to guide you in making decisions. Your Design Consultant must fully understand and appreciate the values of Estidama, and successfully incorporate its requirements into the Villa s design. Once the design is complete, your Contractor will take the project to completion. Like Consultants, a Contractor must also understand the values of Estidama, and implement its requirements from site set-up through to the Villa completion. How do I select a suitable Design Consultant and Contractor? By selecting a qualified Consultant and Contractor, you are forming a team that has the technical and process expertise to meet the PVRS. To appoint qualified Consultants and Contractors, you should look for the following: Have they attended and successfully completed the Estidama Applying the PVRS Course? Does the PVRS Professional have a qualification certificate? Do they have proven Estidama experience? Have they been successful in previous Estidama Design Submissions? Do they have Arabic speaking capability within the organisation? What should you expect from your team? Your team should help guide you through the entire Estidama process including the following: The preparation of an Estidama submission as per your municipality process. Verification of construction through testing and commissioning. Designing and constructing a 1 Pearl compliant Villa. How much will it cost? The costs for designing a Villa to be 1 Pearl compliant are minimal if Estidama is considered early in a project. Ultimately, the long-term cost savings should be greater than the initial costs and, in the end, you will save money over the life of the Villa. The UPC has introduced the Estidama Villa Compliant Products Database, which will help reduce costs even further. Manufacturers and distributors submit their products to the UPC for a rigorous screening process, to assess their technical compliance as part of a list available to all parties. This will save owners time and money when selecting products. Consultants and Contractors have access so that they can also save time, and ultimately cost by selecting correct products. The database includes various sizes of materials, different types of products in a category, and average costs. It offers a one-stop location to compare products, before making selections for the Villa design. Where can I find support?
