OMA’s largest project ever, the CCTV Headquarters in Beijing, is now complete.Rem Koolhaas’ folded tower reinvents the skyscraper and combines China Central Television’s entire production and offices into one multipurpose facility. One tower provides space for broadcasting, while the other is dedicated to services and the two meet in the middle in a puzzling display of building perspective. The energy-efficient tower features local and environmentally-friendly materials and a broad landscaped garden underneath creates a pleasant public plaza for employees, visitors and residents of the city.
Rather than build a sky-high tower, Rem Koolhaas and OMA decided to design for connectivity rather than height so the tower folds in half. One tower provides space for production and broadcasting, while the other is used for services, research and education. The two meet in the middle at a slight cant and the design is a representation of how two sides of the business have different roles but work together for one goal.
energy use for a TV and broadcasting company is high, so to keep it down, the building makes use of energy-efficient climate control systems. In the winter, direct cold air from outside is used to keep production spaces cool and in the summer a chilled water/ice storage system is used. Heating and steam requirements are met from the citywide supply, potentially reducing carbon output per kW of heat output.
The building’s envelope was carefully designed to make use of natural day-lighting, provide a high thermal insulation and protect from overheating and glare. The geometry of the building works to shade a large portion of the facade. Finally, the large landscaped area underneath the tower creates a welcoming and cooling micro-climate, which also works to absorb stormwater and clean the air. An area wide grey water distribution network is used for toilet flushing and cooling tower make up. Finally, the interior materials are non-toxic, and the main part of the materials was domestically produced.
