Estidama Pearl Community Rating System Estidama is an Arab word that is the Arab equivalent of sustainability. As such, the Estidama Pearl Community rating systems can also be translated to read the Sustainability Pearl community rating system. Launched in 2008, Estidama was an initiative of Abu Dhabi in its urban growth plan for Abu Dhabi 2030 aimed at promoting sustainable growth (Madden 2010). In its vision, the government established that sustainability lay at the heart of any development in Abu Dhabi both in the short-run and in the long-run (Salmi et al. 2013). Consequently, the Pearl Rating System arose, as an initiative of the Estidama vision. Essentially, Estidama targets to “create guidelines and regulations to ensure sustainable design operating and maintenance of all types of buildings and communities within the Emirate” (Salmi et al. 2013:1105). It is built upon four pillars: environmental, economic, cultural and social. The Pearl rating system targets all types of buildings and communities. In line with this end, the rating system is tri-faceted. It has a community rating system, a building rating system and a villa rating system (Salmi et al. 2013). Each of these levels has its own criteria as well as its own rating system. There are three levels of certification: design, construction and operational. In the first, the proposed designs are evaluated to determine whether they are consisted with Estidama goals. The pearl system does not only address the assessment of buildings. Rather, it takes an integrated approach whereby it addresses sustainable design at the planning, design, construction and operation levels. Moreover, the system has seven key categories. Each of these categories addresses a particular performance or design metric, and has been referred to in other literature as sustainable development indicators (Singh et al. 2009). These categories are: natural ecosystems, livable communities, resourceful energy, precious water, stewarding materials, innovative practice and integrated development process. While the Estidama system is a very good one conceptually, it has broken down at the implementation stage. As noted, the system is not applied or rather, has not begun being applied to existing buildings. This is despite the fact that Abu Dhabi consumes well above the world average of electricity and water. Another concern for Estidama is that after a mere 6 month of its application, the Pearls rating system was suspended (Salmi et al. 2013). This was for residential buildings and villas and resulted from difficulties in the application of the system. The implication is that while the Pearls rating system had the best intentions for sustainable development in Abu Dhabi, lack of proper planning led to a breakdown. A more tangible outcome of the failure of the Pearl rating system is the foregone opportunity costs. This is because the implementation of Pearls rating system could potentially have led to savings of roughly 11,000GWh in residential sector alone. Yet, this was one of the specific areas in which the implementation of the Pearls rating system failed (Madden 2010). Applicable Case Study The case study that has been chosen for the purpose of evaluation of this study meets the definition of a modular community by the values established within Abu Dhabi 2030. Within the coordinates of 24º27’ North, is Al Bateen area in the emirate of Abu Dhabi, on a micro scale lays the specific neighborhood community chosen as a study object (Fig.1). 434 ZEMCH 2015 | International Conference | Bari - Lecce, Italy
