Why Use A Green Building Certification Rating Program?
Numerous factors influence the decision of which rating system and its associated investments is best for the sustainable city
Availability of sustainable materials in the supply chain Contractor familiarity with materials and approaches/technologies Inflation (both global and local inflation) Contingencies Contracting method (Time & Materials v. Fixed price) Contractor’s fees/profits Design complexity & related expense Occupant consumption behaviours Changes in municipal building codes Integration and inter-relation between supply and demand (robust modeling of vertical and horizontal components) Administrative costs (taxes, licenses, surveys, legal, financing, etc) Bulk purchasing v. individual lot sizes Changing mix of commercial, residential, open space, etc. Time phasing of the Masdar development Advances in technological approaches, cost efficiencies Repair/replacement scheduling for new technologies in UAE climate Government subsidies on operating expenses Government tax schemes/incentives Individual site designs (building orientations & other passive design efficiencies)

There are numerous factors which impact the decision of whether or not to pursue a sustainability rating, and which level to pursue As regulation becomes more strict and increasingly enforced, technological innovation should follow General economic conditions can have a dramatic impact on the cost and other aspects of City’s approach to sustainable development Feb

The impact of sustainable design and construction is controllable; however, there are numerous additional factors which contribute to building performance Benefits from Passive/Active Design vs Behavior Design Quality
Behavior of the building inhabitants/users is difficult to predict, yet has a significant impact on the performance of the building.

Evaluation of each rating system starts with a consideration of how many no-cost/low-cost credits are available, then in determining which mid-to-high cost credits fit project objectives 1) Evaluate Prerequisites and Requirements
2) Determine which credits are irrelevant or not possible for Masdar
Step-by-step approach to attaining desired certification level
3) Evaluate “no cost” and “low cost” credits
4) Evaluate “moderate cost” and “high cost” credits
5a) Evaluate synergistic credits
5b) Evaluate high design impact credits
6) Finalize initial approach to obtain certification

Effective Management of the Supply Chain is Vital Significant product cost and environmental impact is locked in at design phase (e.g. specification)
Manufacturing waste is both an environmental and business cost (e.g. materials efficiency)
The sustainability of sources influences overall sustainability (e.g. supplier standards, material inputs)
Energy sources and efficiency of production impact both cost and greenhouse gas emissions (e.g. demand management)
22

Purchasing with sustainability in mind (e.g. green branding)
Transportation is a common contributor to greenhouse gas emissions (e.g. vehicle efficiency, network optimization)
Product efficiency and durability influence environmental impacts (e.g. water efficiency)
Materials selection and assembly influence end-of-life disposal options (e.g. recyclability, take-back opportunities
