A Singapore investor developed the Nanjing Eco Hi-Tech Island Exhibition Center to unite aspirations of innovation, collaboration, and creativity. The building provides a community gathering space and incubator for environmental and technology companies.

In an area of China with notoriously hot and humid summers, accommodating both density and sustainability can be challenging. In addition to housing the exhibition center program, the client required all office space to be located on two large floorplates while maximizing the FAR of the 24,000 square meter site.

The long horizontal roofline with deep overhangs also provides passive cooling by shading the entire exhibition center from direct solar heat gain. High-performance glazing further minimizes energy loads. The building received a Chinese 2-star low-carbon rating, and the client reports that energy usage is 30% lower than conventional buildings of the same size.

The Exhibition Center serves as a model of sustainability for Nanjing and the region by uniting a range of sustainable design and building performance strategies. Computer and physical modeling shaped the innovative peaked roofline defined by eight “light cannons.” Numerous light studies helped determine the optimal internal shape to bring light deep into the building, ensuring all occupants access to daylight and reducing artificial light usage by 30%.

Performance was one strong driver—another was celebrating Chinese culture and respecting the ancient architectural lessons of the region: buildings anchored low to the earth, with floating, almost hovering roofs, and buildings that seek geometrical symmetry, balance, and order in a reverence for harmony.

Referencing the Zhon and Stone Mountains, the Nanjing Eco Hi-Tech Island is positioned to be Nanjing’s center for the development and practice of high-tech innovation, and an ecological destination and resource for citizens and tourists.
