Giant “light cannons” funnel natural light deep within this new high-tech “eco city” in China. NBBJ designed the Nanjing Eco-Tech Island Exhibition Center as an incubator for innovative technology and environmental companies. To strengthen the project’s sustainability, the design team included green roofs, water retention systems, natural ventilation, responsive facades and geothermal conditioning.
The Nanjing Eco-Tech Park includes an exhibition hall, research offices and residential buildings. The Exhibition Center welcomes visitors a they approach the island from downtown Nanjing. The peaks on the building’s roof each have an oculus that funnels natural light inside the structure. The complex consists of eight, pentagon-shaped office buildings with large interior courtyards.

The architects conducted light studies to come up with optimal daylighting and shading strategies for different times of the day and year. Light gets diffused by the cone geometry of the light cannons, while the overhangs function as passive solar shading devices.
