Supertower Offers Glimmer of Hope in Polluted Chinese City

The Guardian reports on an effort to implement green technology amid China’s boom:

The country is in the middle of the greatest building boom in human history. Six of the world’s 10 tallest buildings completed last year were in China, including the 492-metre-tall Shanghai World Financial Centre. Even taller structures are on their way – such as the Shanghai Centre, 632 metres, and at 600 metres, the Goldin Finance 117 in Tianjin.

But among the giants there is one that could hold out hope for a low-carbon future. The Pearl River Tower, now being erected in , the provincial capital of Guangdong province, is being billed as the most energy efficient superskyscraper ever built.

With wind turbines, solar panels, ­sun-shields, smart lighting, water-cooled ceilings and state-of-the-art insulation, the 310-metre tower is designed to use half the energy of most buildings of its size and set a new global benchmark for self-sufficiency among the planet’s high rises.

Engineers say the tower could even be enhanced to create surplus electricity if the local power firm relaxes its monopoly over energy generation.
