Burj Al Taqa
A skyscraper in Dubai is being designed so that it generates all of
its energy through renewable means such as wind turbines and solar panels.
On top of the tower will be a 200 foot turbine that harnesses the power
of the wind, and an array of solar panels on the roof and a series of
islands that stretches over 161,459 square feet. The tower will also
feature a massive solar shield to protect it from the sun, and vacuum
glazed glass that will reduce the amount of heat absorbed from the extreme
temperatures (up to 50 degrees C / 122 degrees F), presumably meaning
less reliance on traditional air conditioning. Talking of air conditioning,
the main system for cooling the air inside the tower uses a convection
system which pulls in cold air at the ground level, and sucks it up
out of the top of the tower.
