30 St Mary Axe, London, United KingdomWhat is the LEED Certification?
The concept of Gherkin tower as it is usually called by the locals was developed by Norman Foster and Arup engineers, later the construction was carried out by Skanska and Hilson Moran Partnership. The construction ended in December 2003, and the opening ceremony took place in May 2004. The construction was initiated by Swiss Re Reinsurance Company, and they moved the head office here.
The height of the tower is 180 meters; it is situated on the place of former Baltic exchange (it was damaged in 1992 as a result of IRA attack). The architect tried to use maximum natural light and ventilation.
The tower gain the top - LEED Platinum Certification. The building operates with energy-saving system thanks to which it uses much less power. There are specially designed gaps in each floor, creating six shafts. These shafts are used as a unique ventilation system and create a double glazing effect. Air remains between two layers of glass and isolates the building. The shafts remove warm air out of the building in spring and summer and warm the building in winter with the help of the so-called passive solar heating. The system helps to keep down costs for electricity, as sunlight easily infiltrates into the building. Figuratively speaking, the shafts are used as lungs of the building, distributing fresh air through panels in the façade. Thus, the tower doesn’t rely on air conditioning. The 40-storeyed giant offers its visitors shopping facilities, a wide variety of entertainment, including a bar in the dome where the visitors can enjoy a 360° panorama of London.
In 2006 Swiis Re announced about selling the tower for £600 mln. Among the potential buyers there was also the royal family of Abu Dhabi. In 2007 the tower was purchased by IVG Immobilien AG Real Estate Company and Evans Randell Investment Company. The joint purchase cost £630 mln. (almost $1,18 bln). Thus the Gherkin became the most expensive office in Britain. By the way, after the sale Swiss Re continues to occupy the bottom 15 floors, but on lease basis.
Owing to its phallic shape the tower is listed among the sexiest buildings in the world along with Merylin Monroe buildings, Agbar tower etc. The locals named it "playful gherkin" and "crystal phallus". I guess the oblong-shaped buildings will always remind people of phallic symbol. There are hundreds of images of brainy tourists implementing their erotic fantasies on the tower.
The "erotic fame" of the tower inspired also the Hollywood-dwellers: episodes of many films were shot here. One of them is the second part of "Basic Instinct".
