Bloomberg’s new European headquarters in London, designed by Foster + Partners, has been rated as the world’s most sustainable office building. The headquarters have achieved an ‘Outstanding’ rating against BREEAM sustainability assessment method, with a total score of 98.5 percent.Bloomberg building’s environmental strategies deliver a 73 percent saving in water consumption and a 35 percent saving in energy consumption and its associated CO emissions. The deep plan interior spaces are naturally ventilated and a top-lit atrium edged with a spiraling ramp at the heart of the building ensures a creative environment. Integrated ceiling panels combine heating, cooling, lighting, and acoustic functions in an innovative petal-leaf design. The system, which incorporates 500,000 LED lights, uses 40 percent less energy than a fluorescent office lighting system. Rainwater from the roof, cooling tower blow-off water, and gray water sources are treated and recycled to serve vacuum flush toilets. The water conservation systems aim to save 25 million liters of water each year. The use of natural ventilation significantly reduces energy consumption by lowering the dependency on mechanical ventilation and cooling equipment. Smart CO2 sensing controls allow the air to be distributed according to the approximate number of people occupying each zone of the building at any given time, reducing CO2 emissions by approximately 300 metric tons each year.Alan Yates, Technical Director of BRE Global’s Sustainability Group, said, “Projects like these are really important in giving confidence to the industry to experiment,” noted World Architecture News.
