2.6 | Sustainability Design Guidelines
2.6.1 | Introduction The purpose of ‘Milestone 10 – Design Guidelines’ is to provide overall guidance to Globalfoundries when implementing sustainability practices at various phases of the project. This document has been developed assessing Estidama requirements with a brief initial analysis on various building rating systems, as per GF’s advice on October 17th 2010. This report is intended to be a ‘Living’ document to ensure that any changes with regards to project design development are incorporated into the design, while input from various project disciplines are being considered through an integrated approach.
2.6.2 | Analysis on Building Rating System: Estidama -- LEED For Abu Dhabi project (AD01), three building rating systems are potentially relevant: Estidama Pearl Rating System developed by
Urban Planning Council (UPC), Leadership in Energy and Environmental Design (LEED) Green Building rating system administered by US Green Building Council and BREEAM Gulf (BRE Environmental Assessment Method), and a collaborative development by organizations in Qatar, Abu Dhabi and Dubai.
LEED has greater international recognition and is the only system currently at use in the Semiconductor industry; however, LEED credits do not fully factor the importance of water in the region. BREEAM Gulf and Estidama are currently less-known due to being newer, but are weighted more appropriately for Gulf region priorities.
Evaluation of the major criteria categories of each of the three relevant rating systems indicate that only BREEAM Gulf and Estidama emphasize water sufficiently for UAE, where water is scarce and therefore needs stronger emphasis in selection of a sustainability rating system when it comes to true performance. LEED, on the other hand, emphasizes site-related concerns more than water.
PG. 2 Page | 2.6-2
Figure 2.6-1: Comparison of Green Building Rating Systems – Categories Weighting
PG. 3 Page | 2.6-3
Table 2.6 -1 below compares the Green Building Systems and their implementation globally. This gives a good indication of system applicability and recognition.
Table 2.6-1: Building Rating System Comparison
Both the BREEAM Gulf and Estidama processes include 3 phases; design, construction, and operations. A Pearls Design Rating can be used to confirm that the proposed project design is consistent with the goals of Estidama. Once construction is complete as designed, a Pearls Construction Rating will be provided. The Pearls Operational Rating is awarded after 2 years of at least 80% occupancy.
BREEAM also has a certification system for a design stage and a post-construction stage, but unlike Estidama, BREEAM does not require a post occupancy assessment except
for its highest rating (BREEAM Outstanding), which has a mandatory requirement for a ‘BREEAM In Use’ certification within the first 3 years of operation.
LEED has an optional design submission at which no certificates are issued, and has the leanest post occupancy assessment of the three systems. The new changes in LEED 2009 show a slow shift in the direction of post-occupancy assessment with the new requirement that the USGBC has access to projects’ Whole-Building Energy and Water Usage Data.
PG. 4 Page | 2.6-4
Figure 2.6 -2: Certification Process
As BREEAM Gulf and Estidama have not been widely used in UAE, it remains to be seen how the amount of paperwork and
engineering/modeling/administrative effort will compare between the three systems.
Figure 2.6-3: Capital Investment per Rating System
We have been advised that LEED certification is a GFGF corporate requirement and shall be pursued. Estidama is now closely-tied to Abu Dhabi regulations and as of 1st September
2010, all new buildings must meet the minimum requirements in order to receive approval for construction to begin. The Estidama Pearl Rating System, developed by
PG. 5 Page | 2.6-5
the Urban Planning Council (UPC) mandates that all buildings achieve at least ONE pearl rating. All government buildings or government led investments will be required to meet the requirements of TWO pearl rating.
Considering mandatory requirement from UPC to pursue Estidama and GFGF corporate mandate for LEED certification, GF is considering pursuing both Estidama and LEED certification for AD 01 project. This document however, assesses only Estidama certification requirements consistent with client’s request on October 17th 2010.
2.6.3 | Project Boundary for Certification
Project Boundary Definition
The building rating systems are generally not geared towards industrial applications like FAB. GF was clear in their direction in July 6, 2010 presentation that they would like to get the entire Phase 1 development certified and not just the office block.
GF shared their approach for project certification boundary in the sustainability review session in Malta on August 12, 2010. It was informed that certification boundaries as shown below were selected to facilitate the energy modeling and baseline calculations. GF mentioned that they had series of discussions with GBCI to agree on the certification boundaries as shown below. Separate project boundaries were established for the Administration and FAB Building, with the utility systems (CUB building) included in the energy model calculations for the FAB.
Figure 2.6-4: Project Definition – Malta FAB 8
Urban Planning Council called for a meeting to discuss with their Estidama team regarding the Pre-concept master plan submission. During this meeting with UPC, project certification boundary was discussed. Estidama team supported the idea for separate certification for Admin and Fab building considering their function and use. In addition, it was agreed that the CUB will be included in the
certification. Please find enclosed in Appendix 2.7 I the UPC response.
Project Boundary Options and
Selected Approach
Further discussions were held in sustainability review meeting on Sep 13, 2010 wherein certification boundary options were discussed
PG. 6 Page | 2.6-6
in detail. GF team concurred that it will be important to select consistent project boundaries for LEED and Estidama. It was agreed to proceed with Option 1 project boundary for certification at this stage. The FAB certification boundary will include the
CUB and GF team expressed confidence that there will be no concerns with Green Building Council (GBCI) to have slightly modified boundary selection for Abu Dhabi AD01 project.
Option 1: Select Project Certification Boundaries Suggested by Estidama Team
PG. 7 Page | 2.6-7
Option 2: Select Project Certification Boundaries Accepted by GBCI on FAB 8, New York
Option 3: Separate Project Certification for Admin, FAB and CUB
2.6.4 | Sustainability Workshops
Coordination Meeting with UPC
An initial meeting was held on the 29th of August with representatives from Urban
Planning Council, GF and CH2M HILL. The main purpose of the meeting was to discuss the Pre-Concept Plan submission and the way forward. UPC notes from the meeting can be found in the Appendix 2.7-I.
PG. 8 Page | 2.6-8
The main outcome of the meeting can be summarized as follows:
Estidama 1 Pearl will be a regulatory requirement for all buildings in Abu Dhabi as of September 2010
For governmental funded projects 2 Pearl rating will apply as a minimum requirement
Estidama certification will require GF to include the Central Utility Building
Project Sustainability Charrettes
Sustainability Charrettes, one for each building type, will be undertaken at the programming stage to ensure that client values are considered at an early stage of the design.
The main objective of these Charrettes is to assess each building anticipated rating, evaluate different design strategies, identify challenges and opportunities, as well as credit synergies and facilitate decision making process. During the Charrettes the Preliminary Estidama scorecards (please refer to Appendix) will be used to guide the brainstorming discussions.
Key Project Stakeholders that will be engaged during the workshops are: GF Sustainability, Design Technical Leads (Mechanical, Electrical, Water Building Systems, Water Processes Systems, Architect, Planning Team, and Logistics).
The main output of the workshops will be a revised set of the Preliminary Estidama Scorecards incorporating the input from various project stakeholders, while taking into consideration various client decisions during the evaluation process.
Coordination with GF
Weekly Sustainability meetings have been scheduled with the client to discuss on key
issues, decisions need to be taken and monitor progress.
2.6.5 | International Energy Conservation Code Review The International Energy Conservation Code (IECC) is a building code created by the International Code Council and is updated every three years. It establishes minimum standards for energy efficient buildings using prescriptive and performance-based provisions for residential and commercial buildings. The code’s intent is to establish criteria for energy conservation with provisions that do not unnecessarily increase construction costs.
It addresses the energy efficiency requirements for the design, materials, and equipment used for new buildings construction, renovations, and construction techniques. The Code applies to:
Wall, floor, and ceiling
Doors and windows
Heating, ventilating, and cooling systems and equipment
Lighting systems and equipment
Water-heating systems and equipment.
Materials
Table 2.6 -2 below includes a high level review of the IECC for commercial buildings. At later stages during the design the project team should review criteria for each building type to determine if provisions are achievable. The industrial nature of the FAB and CUB buildings and high-hazard provisions of the 2009 International Building Code (IBC) may warrant review of applicability. IBC provisions (based on life safety) shall supersede energy criteria.
The advantages to IECC compliance include sustainable development, reduced consumption, enhancing quality of living and reducing energy costs. Other 2009 I-codes
PG. 9 Page | 2.6-9
may also contribute to sustainable development as follows:
International Plumbing Code (IPC): water and energy conservation
International Mechanical Code (IMC): Carbon dioxide reduction,
improved indoor air quality, reduction of ozone-depleting refrigerants, energy conservation, harvesting renewable resources such as solar power, etc.

2.6.6 | Integrated Sustainability Decision Model and Cost Benefit Analysis The Infrastructure Sustainability Decision Model (ISDM), developed by CH2M HILL, takes a triple bottom line approach, along with targeted Building certification requirements, to guide design, construction, materials
management, and operational decisions. The ISDM for GF will be arranged to assess various scenarios for two building types of the first development phase (AD-01) of the GF FAB Park: Administration building and the Industrial unit (FAB) including CUB.
PG. 12 Page | 2.6-12
Parameters To Be Considered
The Decision Model has the capability to assess strategies on the following infrastructure components:
Potable Water
Energy
Solid Waste Management (For office Building only)
Embodied Carbon (Material Selection for: Concrete, Rebar, Structural Steel)
Scenarios To Be Developed
The model has the capability to assess up to 5 scenarios. The data will be arranged so as to assess Business as Usual (BAU) case against various conservation measures in line building certification credit goals, which will be defined as percent reduction of water, waste, energy from BAU.
The different scenarios for both building types shall consider the following:
Administration Building
BAU: will be established based on previous experience in Abu Dhabi
Water: scenarios will consider water conservation fixtures
Energy: scenarios will consider measures such as Higher Thickness of Roof Insulation, Triple Glazing etc.
Solid Waste Management scenarios will include waste segregation and reuse.
Embodied Carbon: will provide options to choose different materials for Concrete, Rebar and Structural Steel
FAB Unit
Baseline will be established based on common practices or BAU
technologies while various measures will be compared against BAU by indicating the capital cost, energy demand and O&M cost variance.
Water: scenarios will consider Make-up Air Units (MAU) condensate water reclamation, FAB water reclamation etc.
Energy: scenarios will consider measures such as use of dual temperature chilled water system, MAU Variable Frequency Drives (VFDs), Utilization of Fan Energy for Reheat, Premium Efficiency Motors etc.
Embodied Carbon: will provide options to choose different materials for Concrete, Rebar and Structural Steel
ISDM Output
The ISDM for GF will have the capability to run various scenarios on water, energy, materials and waste strategies to be considered with the associated capital and operational costs as a result of saving energy, water and using sustainable materials.
The model capabilities are presented in the Appendix with a dashboard arrangement demonstrating high level calculations on capital cost and additional cost & carbon saving during operation per building type.
2.6.7 | Technical Design Guidelines In order to achieve the required building certification system, it is important to incorporate relevant requirements into the design guidelines and project specifications.
A set of preliminary guidelines has been developed to ensure the implementation of the required strategies with regards to Construction Waste Management, Construction Indoor Air Quality, Minimum
PG. 13 Page | 2.6-13
Energy Performance and Energy Reduction, Erosion and Sedimentation Control Management Plan. A brief overview of each Design Guideline is provided below; the actual Guidelines can be found in the Appendix.
These guidelines have been developed in accordance with the Estidama relevant credits and they should be reviewed at the end of the UPC Detailed Review to ensure that all Estidama requirements are incorporated.

2.6.8 | Preliminary Scorecards
Preliminary Scorecards Purpose
Preliminary Scorecards have been prepared for the Administration and FAB (including CUB) buildings consistent to client decision with regards to Project Boundary definition. The purpose of preparing these preliminary scorecards is to use them as guidance for the Estidama Certification process.
At this initial stage of programming, the scorecards can be viewed as valuable tools that can be used to:
PG. 18 Page | 2.6-18
Identify credits relevant to the project scope, building use, overall vision and GF corporate policies
Identify Credits that can be easily achieved with minimum effort and least additional cost
Identify potential opportunities that can be refined via ROI analysis in Design phase
Identify Credits that require further screening between the project stakeholders through Sustainability Charrettes at this initial stage
Provide an initial evaluation of the building’s expected rating while identifying challenges and opportunities
Assist in decision making for GF and Design Team to follow certain design strategies
Identify ‘follow up’ tasks in order to facilitate credit intent implementation
During later stages, during design, upon design completion and as the project
progresses to the construction phase the team can monitor actual performance for each intended credit.
The preliminary scorecards, since are developed at an early stage with limited information available, followed a rather conservative approach. Easy to achieve credits, with minimum effort or additional cost, were identified as intended (‘Yes’), while a larger number of credits were indicated as ‘possible’ with the intention of generating brainstorming discussions within the design team (Sustainability Charrettes, Section 3) and propose different options of design strategies for GF to consider.
Preliminary Scorecards
Summary Overview
A summary overview of the scorecards per category is provided below. The detailed scorecards can be found in the Appendix. Table 2.6 -6 below summarises credits identified per category for both buildings.

management from design to end of life disposal.
Figure 2.6-7: Supply Chain –Key Parameters
For a typical building, 90% of carbon footprint (embodied carbon) and around 80% of building costs are attributed to just three
materials: Concrete, Steel and curtain walling windows.

For an effective strategy, we decided to focus on concrete, structural steel and rebar as they are the major materials with significant impact for AD01 development. A rough initial estimate of materials for AD01 is indicated below:
Concrete: 120,000 cubic meters
Steel: 14,000 metric tons
Rebar: 5,000 metric tons
The suppliers listed below are based in the UAE. This list is indicative and it requires further investigation to identify additional local suppliers and evaluate their building products against Estidama requirements. It is recommended therefore, that a comprehensive pre-qualification process for suppliers is established at the design stage of the project to evaluate sustainability performance of their products (together with other criteria such as cost, availability, delivery timeframe etc.) and identify potential strategic partnerships.
Concrete
Cast in Place
The manufacturing of cement is one of the most CO2 intensive processes on the planet. It is estimated that 6% of the world’s carbon production will come from the manufacturing of cement. Cement is also one of the most widely utilized building materials as it is a key ingredient to the ready mix concrete production and usage.
The concrete mixtures incorporating recycled-content, Portland-cement-reducing admixtures such as fly-ash are desirable in order to obtain Material Selection related Credits under Estidama building rating system.
Products listed below incorporate recycled content or have desirable environmental attributes:
AL FALAH READY MIX
AL FALAH READY MIX owns 36 production plants strategically located over the UAE.

Ground Granulated Blast Furnace Slag
Cement production is energy-intensive and polluting; concrete mixtures incorporating recycled-content, performance-enhancing, portland-cement-reducing admixtures such as fly-ash are desirable. Recycled materials used in place of mined stone aggregate - such as slag, a byproduct of steel production – ease landfill burdens and can improve the concrete's strength-to-weight ratio and thermal properties. Products listed here incorporate recycled content or have other desirable environmental qualities.
GULF CEMENT CO
Gulf Cement Company claims annual production capacity of 2.5 million tons cement and 1.3 million tons clinker. GCC has been awarded with ISO 9002:1994, ISO 9001:2000, ISO 14001:2002. GCC grinds and sells pulverised slag as Ground Blast Furnace Slag (GGBS) complying with BS 6699. Also, their product carries the BSI KITEMARK.
SHARJAH CEMENT FACTORY
Sharjah Cement Factory produces Portland Cement, Moderate Sulfate - Resisting Portland Cement, Sulfate - Resisting Portland Cement, Ground Granulated Blast furnace Slag.
GGBS produced is manufactured to comply with the requirement of BS 6699 and exceeds the minimum strength and fineness requirement by a considerable margin. Their product carries the BSI KITEMARK.
Precast Concrete Slabs
For the production of precast concrete, concrete is cast in a reusable mould, cured in a controlled environment, transported to the construction site and lifted into place.
MAMMUT TECHNOCRETE
Mammut Technocrete (MTC) was formed in 2005 to manufacture pre-cast concrete products for the contracting sector. Their factory commenced supply to the UAE market within the year of 2005 with the ability to provide material with recycled concrete. Using precast concrete has the following advantages:
100% Elimination of slab formwork
50/75 % reduction of slab reinforcement work
15/50 % reduction of slab concreting work
Reinforcing Steel (Rebar)
A rebar, or reinforcing bar, is a common steel bar, and is commonly used in reinforced concrete and reinforced masonry structures. It is usually formed from carbon steel, and is
given ridges for better mechanical anchoring
into the concrete.
