30 St Mary Axe
40-storey tower, Mary-AIX, office Swiss Re, located in the vicinity of skyscrapers in the financial center of London. This is the first skyscraper, which claims the title of Environment. Besides, this is not the only office building, its first floor - open public areas, Plaza, serving all workers in the area. At the upper floors are offices for staff restaurants and guests. SkyLight top provides a fantastic view of London with a circular view. This is a radical thing in terms of technology and architecture, spatially and socially. And from the outside, and inside it is something not quite similar to conventional office buildings.
Round in terms of expanding tower in the middle and then tapers Above. This form grows out of the specificity requirements seats. The building does not look so cumbersome, would have looked like an ordinary rectangular skyscraper same area; due to the fact that the building thin, it casts shadows less, increases the transparency of the building and increases penetration of sunlight into the lower floors. In the middle of the tower maximum office space; what it tapers Above, increases the amount of sunlight in the area.
Aerodynamic shape naturally wind makes the building envelope that minimizes the swirl of air and cloud formation. The air does not move down, as happens with conventional rectangular skyscrapers that protects the comfort of pedestrians. Tests in wind tunnel proved that the construction would substantially improve the air in the surrounding area. In addition, the natural movement of air around the building creates constant pressure difference different facades, which allows ventilate the building naturally.
Conceptually, the building is based on the draft Klimatrofis, which Bakminister Fuller created in early 1970 - x. The project combined the office space with a glass skin free form, creating a special microclimate. Then the building of this form has been difficult to build. Today, after 30 years, computer technologies allow the creation of such a space. The form allows a building to actively use natural ventilation in such a way that 40% of the time artificial conditioning can be turned off. Light mine involves a significant degree of natural light. Balconies on the light-mine was an excellent point species.
If the building took place every construction site, the street next to it would be too narrow. Instead, the building has a small circular base, consisting of a central nucleus and a grid of intersecting steel elements. The traditional building would have a very powerful central authority, but, thanks to the rigidity of double diagonal steel grates, the central element can be made very thin, making it possible to leave more space.
