Norman Foster’s famous buildings: high-tech architecture meets ecological technology

The Gherkin: an energy-efficient, high-tech skyscraper in London

Norman Foster is responsible for several famous designs in London. His Millennium Bridge, for example, carries pedestrians across the Thames between the Tate Gallery of Modern Art and St. Paul’s Cathedral. Another striking feature of the skyline is the headquarters of Swiss Re, which was completed in 2004 and has since been known as the Gherkin.

The glazed façade not only opens up the building to light and spectacular views, but also allows energy-saving ventilation and air conditioning. A number of atria between the floors provide natural ventilation, so that the air-conditioning system rarely has to be used; thus halving energy consumption in the environmentally-friendly skyscraper.

Copenhagen Towers: upcycling in the green heart of Denmark

Sustainability was also a guiding principle in the design of the Copenhagen Towers, which were completed in 2015 in the newly developed area of Ørestad. The ensemble consists of a 22-storey office tower connected to a lower-rise building. The atrium is the green heart of the building, with a dense “forest” of olive trees. Curved wooden profiles in the steel structure of the glass roof as well as curved wooden benches emphasise the natural ambience.

The Copenhagen Towers are also a model for ecological building projects because Foster uses predominantly local and recycled materials. The interiors, for example, feature concrete floors made from local construction waste and ceiling cladding made from PET plastic and felt. Combined with photovoltaics and an innovative groundwater-based heating and cooling system, the complex uses up to 45 percent less energy than an ordinary building of its type.

Apple Park: Norman Foster’s superlative structure

With the design of the new Apple headquarters in Silicon Valley, Norman Foster has created architectural superlatives in many different respects – entirely in the spirit of the late Apple boss Steve Jobs. With the new Apple Park in Cupertino, Jobs wanted to create a place that would bring together all employees while creating a seamless connection between the high-tech workplace and nature.

In line with this vision, Norman Foster designed the new company headquarters in the form of a ring that, at just under half a kilometre in diameter, is bigger than the Pentagon.

Surrounded by a green space with around 9,000 newly planted trees, more than 12,000 people work under a huge carbon roof behind 13.7-metre-high glass windows around the entire ring. The Apple Campus is powered by 100 percent renewable energy and opened in 2018.
