Solar panels on the world's tallest tower will heat 140,000 litres of water every day.
The world’s tallest building is using solar panels to heat 140,000 litres of water every day that is being used by its residents, its developer Emaar said on Sunday.
The solar panels on the Burj Khalifa are expected to save the equivalent to 3,200 kilo watts per day and 690MWh of energy every year.
Other energy saving initiatives on the building, which opened in January 4, include a system to collect condensation from the air conditioning equipment which when operational will provide 15 million gallons of water a year.
Last month, Burj Khalifa was plunged into darkness to observe Earth Hour, the global initiative against climate change.
Arab states have been critised for not doing enough to push renewable energy products despite being some of the biggest emitters of greenhouse gases on a per capita basis. Carbon dioxide emissions in the region are increasing at one of the fastest rates in the world, nearly doubling between 1990 and 2003, according to a UN Arab Human Development Report
Masdar, the Abu Dhabi energy firm, plans to invest $15bn in renewable energy projects while Egypt plans on supplying 20 percent of its energy needs from renewable sources by 2020.
"that is being used by its residents" - not just yet AB. There are no residents. But this water heating is a good idea. The condensation collection system is not really an energy saving initiative. You've already expended the energy to cool the glass on which the summer humidity condenses out. Better insulation would save cooling costs. And anyway they had to do something with the condensate - they couldn't just let it cascade from 800m up. What it does save is water. Which is, I suppose, indirectly an energy saving in a place where it is nearly all provided by desalination. Anyone know if the lifts are working again to the viewing area?
