Wind And Solar Powered Dubai Skyscraper
Skyscraper to be built in Dubai will generate 100% of its energy needs with wind and solar power
news | energy efficiency | general
The
Burj al-Taqa (
Energy Tower) to be build in Dubai will produce 100% of its electricity needs from a 60 metre diameter roof-mounted
wind turbine and 15,000 square metres of
PV solar panels. Another 17,000 square metres of
solar panels will be located on a nearby artificial island visible from the tower. Any excess electricity generated will be used to extract hydrogen from sea water by
electrolysis to be used to generate electricity at night through
hydrogen fuel cells.
The tower will rise to 322 metres and have 68 storeys. Construction will cost in excess of £200 million.
Earlier this year work was completed on the
Bahrain World Trade Center - a pair of skyscapers joined together by three integrated
wind turbines. These wind turbines - a world first - will provide 11-15% of the energy needs of the buildings. However the
Burj al-Taqa will be the first 100% renewable energy powered skyscraper in the world, and the first to have a huge wind turbine generator installed on its roof.
Burj al-Taqa
The
Burj al-Taqa has been designed by German architect Eckhard Gerber from the ground up to be as
energy efficient as possible. The whole building will be cylindical to reduce the surface area exposed to the sun, and a protective
solar shield will wrap around two-thirds of the exterior of the building from the ground to the roof protecting the side of the building in direct sunlight to keep it out of the rooms.
The windows will be glazed with cutting edge
vacuum glazing (so advanced they will only be available on the market after 2008) which will insulate the building against the scorching 50+ degree outside heat. These units will transmit 2/3 less heat than the best products on the market today and will slash the amount of electricity needed to power air conditioning units.
The
air-conditioning itself will use air pre-cooled by seawater to keep the temperature of the interior of the tower to just 18 degrees Celcius. At the same time water is cooled which is pumped around the ceilings at each level to help keep the temperature down without the need to blast so much cold air out of air-condition ducts.
Mirrors installed on the roof of
Burj al-Taqa will direct a cone of light through the centre of the building
bathing every floor of the building in free natural light.
Eckhard Gerber
The architect of the Burj al-Taqa
Eckhard Gerber (pictured above) is also planning similar
zero-emission office buildings in Riyadh, and Bahrain.
Of the Burj al-Taqa Gerber says "There's nothing like this in the whole world. This kind of accomplishment is very rare."
