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.
