Russia Tower is expected to be the tallest building in Europe, and one of the tallest in the world, coming in at over 2,000 ft tall, just behind Burj Dubai.

Furthermore, it will be the largest building in the world with a natural ventilation system.

A striking new addition to the skyline of Moscow City, this mixed-use project will incorporate apartments, hotel, office and leisure space, will have an ‘energy cycle’ that will pioneer sustainable architecture and reinforce the economic and social vitality of Moscow City.

Foster + Partners designed the building with an "energy cycle" system, which is a hot water circuit that runs through the building distributing the energy to regulate temperature and heat water. The energy cycle system is intended to chart new territory in sustainable architecture.

The pyramidal design also maximizes exposure to natural lighting, which provides both light and warmth in the winter. Additionally, there will be a series of green skygardens rising up the core of the building that draw in natural ventilation and provide social space for the occupants.

Construction began in 2006 and is expected to be complete in 2012.
