The Burj Khalifa in Dubai, UAE is the world’s tallest building. Now, it may be one of the world’s greenest. Developed by Emaar Properties, the building has recently tapped into solar power to meet hot water needs of residents and tenants.
You might think of Dubai as a region built on the fortunes of oil. Certainly, one can chalk up a fair amount of the opulence of Dubai to fossil fuels. But these days, even the Middle East area is looking to renewable energy for the future.
According to a recent press release, the Burj Khalifa is aiming to meet sustainable development initiatives of the UAE by using solar panels to heat 140,000 litres of water every day:
The solar powered water brings energy savings equivalent to 3,200 kilo watts per day and 690MWh of energy per annum.
What better place to draw on solar energy than the top of the world’s tallest building?
At the Burj Khalifa, solar hot water is generated by a solar heating system installed/operated by SOLE UAE Solar Systems. There are 378 solar collector panels that collect and convert solar energy into heat for the entire building’s 140,000 liters of water in a mere 7 hours of solar radiation. In addition to the solar hot water system, condensate from the air-conditioning equipment in Burj Khalifa is reclaimed to cool potable water from Dubai Electricity & Water Authority. The condensate is collected in an on-site irrigation tank and used for tower’s landscaping.
Burj Khalifa, which anchors downtown Dubai, is a 500-acre mixed-use tower featuring luxurious residences, commercial suites and the Armani Hotel and Armani Residences. At the Top, the world’s highest observatory with an outdoor terrace, is one of Dubai’s most popular attractions.
