With its huge treelike structure, the Qatar National Convention Center is one of the world’s most iconic energy-efficient convention centers built to date. The LEED certified building, captured in new shots by Portuguese photographer Nelson Garrido, was designed by Japanese architects Yamasaki Architects, who based their proposal on the concept of architect Arata Isozaki. The center officially opened on 4 December 2011 in Doha, and offers a 4,000-seat theater space, three auditoria, 52 flexible meeting rooms and many other spaces for hosting local, regional and international events.
Arata Isozaki’s initial concept was based on the holy Islamic Sidra Tree, which symbolizes the end of the seventh heaven.
Huge steel columns create a tree-like appearance and an illusion of two trees supporting the roof canopy.
The columns grow from two concrete bases along the façade and divide into four branches.
The branches have octagonal cubes as structural cores.
The $720 million energy-efficient project was built according to US Green Building Council's Leadership in Energy and Environment Design (LEED) gold-certification standards and is the first of its kind in the region.
The building has 3,500 square meters of its roof area covered in solar panels that contribute about 12,5% of the building’s total electrical consumption.
