Beijing’s largest exhibition & convention venue, CIECC expands the city’s existing facility to over 611,000 m2 with 9 new exhibition halls, 3 reception halls, a conference centre for 9,000 delegates and a hotel with 410 rooms. CIECC’s composite roof system creates an insulated, lightweight, large-span structure providing column-free adaptable spaces. Achieving the highest certification of China’s Green Building Program, the centre uses smart building management systems with hybrid natural ventilation, rainwater collection, grey water recycling, and photovoltaics for on-site energy generation.
