Moscow’s rapidly growing skyline will soon feature an eye-popping new addition: Crystal Island, which will be the world’s biggest building when completed. Sir Norman Foster’s mountainous 27 million square feet spiraling “city within a building” will cost $4 billion and it is scheduled to be built within next 5 years.



And as we’d expect from Foster + Partners, this soon-to-be world’s biggest building will also incorporate a number of sustainable design features into the overall scheme. The exterior facade will be solar responsive and will include solar panels which, along with wind turbines, will generate electricity for the huge tower. Natural ventilation will be provided thanks to numerous strategically placed large atriums. The internal environment will also have dynamic enclosure panels slotted into the structural framing that will allow daylight to penetrate deep into the heart of the structure; the panels will also be controlled to modify temperature inside the building – closed in winter for extra warmth and opened in summer to allow natural ventilation. Energy management is at the heart of this structure, several on-site renewable and low-carbon energy generation projects are planned. - via Inhabit
