As previously reported on Carboun, Masdar City – the $22 billion project of the Abu Dhabi Future Energy Company (Masdar) – is currently under construction and is due to be completed in 2016. As the the first zero-carbon emissions and zero-waste city, the master plan for Masdar City integrates many passive design and planning strategies with renewable energy production to achieve its ambitious sustainability goals.
At the center of Masdar City lies its first building, the Masdar Headquarters, which will become the new home of Abu Dhabi’s Future Energy Company, as well as the secretariat of the International Renewable Energy Agency (IRENA). The building – together with other key building -will act as an anchor and a catalyst for the development of the city.

UPDATED – The King Abdullah University of Science and Technology (KAUST) at Thuwal (near Jeddah) in Saudi Arabia was recently announced as one of the winners of the American Institute of Architects’ Top 10 Green Buildings awards for 2010.
The new international graduate-level research university was established by the government-owned Aramco, the world’s largest energy corporation, to drive innovation in science and technology and to support world-class research in areas such as energy and the environment. The campus project was designed by HOK Architects and was completed in September 2009.
KAUST’s new campus is Saudi Arabia’s first LEED certified project earning a Platinum certification, the highest rating in the United States’ green building rating system At 496,000 Square meters, the project also represents the world’s largest LEED Platinum project.

UPDATED – In April 2010 the Estidama program of the Abu Dhabi Urban Planning Council partially released the first version of its rating system suite, The Pearls Rating System for Estidama. The release included the design and construction portions of the the rating system suite which includes rating systems for buildings, villas, and neighborhoods.
Prior to its release Estidama has occasionally referred to the upcoming system as one that learns from its established predecessors, the British BREEAM rating system and the American LEED rating system (BREEAM stands for British Research Establishment Environmental Assessment Method, and LEED stands for Leadership in Energy and Environmental Design). The decision to learn from these rating systems was not only to learn from their mistakes but also to help create a system whose requirements are familiar to the market. On the other hand, the Estidama program asserted that the Pearls Rating System would not be a direct copy of either systems given the environmental and cultural differences of the Emirates
Given the debates that exist amongst practitioners and researchers on both sides of the Atlantic on the merits, shortcomings, and differences between BREEAM and LEED. An analysis of Estidama’s Pearls Rating System in comparison to these two established rating systems was necessary. The first version of the Pearls Rating System for Estidama will be compared to the latest version of the LEED rating system, LEED 3.0 (also known as LEED 2009), and the latest update of the BREEAM rating system, BREEAM 2008.

Copyrights: Perkins+Will In February 2010, the design for Al-Birr Foundation Headquarters in Riyadh, Saudi Arabia, has been named as the winner of the 2010 Architectural Review / MIPIM Future Projects Awards under the ‘tall buildings’ category (Image 1). The unbuilt project, designed by Perkins+Will’s New York Office, was commissioned for Al-Birr Foundation, a non-profit organization aimed at alleviating poverty and caring for disadvantaged families and children.
The Design
Of the many features of the design of the 59, 000 sqm tower, perhaps the most interesting is how it was concieved as a sustainable urban tower that responds to the environmental characteristics and the microclimate of the city of Riyadh, which is a challenging climate to address given the extreme solar exposure and the heat conditions of Riyadh.
Faced with these climatic conditions and a deep plot of 1000 x 1200m, the projects’s designers response was to rethink the high rise typology in this context. The design’s most visible response to the climate is the building’s envelope which was designed as a large rectangular frame of brise-soleil enclosing the occupied parts of the building. This shading frame was designed to respond to both the different amounts of solar radiation received by each elevation as well as the interior spaces behind it. To achieve this result, a mapped shading mesh was devised to provide varying levels of openness for different locations of the different elevations depending on its solar exposure and its spatial/contextual influences. The result was an envelope that resembles a mesh of varying densities surrounding the building and simultaneously protecting and revealing the activities behind it.
This proposed design solution thus helps the building reduce its solar heat gain while maintaining its views towards the city (FIgure 1). In addition to this shading effect, the mesh-like dynamic treatment of the envelope has also helped animate the building’s expression with the dense and sparse zones of the facade adding a dynamic effect to what otherwise may have become a static pure form.

The Carnegie Center for Global Ecology in Stanford is a research facility that combines Laboratories and office spaces. The 1100 Sqm building was built on a previously developed plot of 7.4 acres. The client’s main concerns were lowering the carbon emissions tied to the building’s energy use as well as the embodied carbon emissions of building materials. Flexibility over the short and long term was also of utmost importance to the client who wanted to allow for the expansion and contraction of research teams.Like Many of the Climates of the Middle East, Stanford has an arid climate with a long dry summer season, and benefits from northwest breezes.

Energy use in buildings accounts globally for nearly 40% of global energy consumption and 36% of total energy-related carbon dioxide emissions. These percentages are almost equally split in two halves between the industrialized countries and the rest of the world (Price et al., 2005).
Our buildings use energy in two ways; first, to keep our interior environment comfortable through cooling, ventilation, and heating our spaces; second, to power the appliances that we have come to depend on such as home appliances, lighting systems,computers, and other office equipments. To reduce this high percentage of energy use and the resultant carbon dioxide emissions, both sources of energy use in buildings must be addressed. The first energy use can be addressed by improving the building envelope’s efficiency in order to reduce the need to condition its spaces (cooling, heating, and ventilating). This method of conserving energy use includes a vast array of passive low energy design strategies that depend on the building’s environment and context. The second energy use can be addressed by improving the efficiency of appliances and equipment used inside buildings including improving the efficiency of lighting and dissemination of improved stoves for cooking in rural areas.

A pan-Arab survey conducted by the Arab Forum for Environment and Development (AFED) found that a resounding majority of 98% believed that the climate is changing.
The survey sample which included a big segment of educated people (who more reflect the views of those nearer to decision making, than proportionally reflect the actual population mix) showed that only a small portion of 5% said they did not understand what climate change was, reaching a maximum of 11% in Syria. However, 95% of those who said they did not understand what climate change was, still answered that they believed the weather was changing, (Figure 1). A majority of 89% also thought that this change was due to human activities, including excessive use of energy and depletion of resources, (Figure 2). These results clearly showed that climate change has become widely accepted by the public in Arab countries as a fact which needs to be addressed. Moreover, the survey showed that the skeptical attitudes which prevailed among some groups on the facts and causes of climate change, either denying it entirely or limiting it to natural causes, are decreasing.
