World's largest LEED-Platinum project finds place in Top Ten Green Projects

Published: 23-Apr-2010

HOK-designed King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, which is the world's largest LEED-Platinum project, has been chosen by the American Institute of Architects (AIA) Committee on the Environment (COTE) as one of the 2010 Top Ten Green Projects.

Designed by global design practice HOK, the 6.5 million square feet KAUST is also Saudi Arabia's first LEED-certified project.

The 26-building campus is integrated with a series of strategies to create a low-energy, sustainable project in an extremely hot, humid climate. HOK employed five strategies that borrow from local culture and traditions to solve environmental issues - traditional Arabic city-inspired structuring; traditional souk or Arabic market-inspired streets; Arabic Bedouin tent-inspired roof system; passive ventilation strategies; and ‘mashrabiya’-inspired screening system.

The campus is structured like traditional Arabic cities, by compressing it as much as possible to minimize the amount of exterior envelope exposed to the sun and to reduce outdoor walking distance. Mimicking the traditional souk or Arabic market, shaded and passively cooled circulation streets are characterized by dramatic light and social spaces. The campus features a monumental roof system inspired by the Arabic Bedouin tent. This roof system spans across building masses to block sun on building facades and into the pedestrian spine and facilitates natural ventilation. Solar panels covering the surface capture the sun's energy. The design of iconic, solar-powered wind towers are inspired by the passive ventilation strategies of the traditional Arabic house. These wind turbines harness energy from the sun and wind to passively create air flow in pedestrian walkways. The windows and skylights at the buildings are shaded via an integral shading system similar to that of Arabic screening called 'mashrabiya’ that reduces heat loads while creating dramatic dappled light.

The project is said to deliver exceptional performance in the areas of water (100% wastewater reuse, 42% water reduction), energy (27.1% annual energy cost savings, 7.8% on-site renewable energy, 80% of glazing shaded year-round) and materials (20% recycled content, 38% regional materials, 99% wood from Forest Stewardship Council sources and 80% construction waste management).

The winning projects will be showcased at the AIA 2010 National Convention and Design Exposition, from June 10-12 in Miami. The 2010 AIA/COTE Top Ten Green Projects is an annual award program that honors sustainable projects resulting from an integrated approach to architecture, natural systems and technology.

Previous HOK-designed projects that have been named to the AIA Top Ten Green Projects list include: San Mateo County Forensics Laboratory and Coroner’s Office – San Mateo, California; Edificio Malecon Office Tower – Buenos Aires, Argentina; National Wildlife Federation Headquarters – Reston, Virginia; Nidus Center for Scientific Enterprise – St. Louis, Missouri; World Resources Institute Headquarters Office – Washington, DC; Missouri Historical Society Museum Expansion and Renovation – St. Louis, Missouri; and SC Johnson Commercial Products Headquarters – Racine, Wisconsin.
