Pearl River Tower

Guanzhou, China

The firm's most recent commission is the 1,000-foot-tall Pearl River Tower in Guanzhou, for the Guangdong Tobacco Company, which SOM says will be one of the greenest buildings in the world. The project's green elements include a water-retention area; basement fuel cells, which produce electricity by extracting hydrogen from natural gas; façade-integrated photovoltaics; a condensate reclamation system that collects water and reuses it; and stack ventilation, which captures and uses heat caught between the building's double-layer facade. The building's curved shapes form two apertures where air is directed into wind turbines.
