World’s Tallest Broadcast Tower Highlights Green Push

Builders of Tokyo Skytree, the 65 billion yen ($656 million) broadcast tower almost double the height of the Empire State Building, say they aim to make their mark on more than just the Japanese metropolis’s skyline.

A combination of heat pumps and water tanks for its district heating and cooling systems aims to reduce carbon emissions as much as 48 percent compared with similar projects without a centralized system, said Shinichiro Konno, the managing director of a company that helped develop Skytree.
