The US Green Building Council has implemented - with some success - a program called LEED (Leadership in Energy and Environmental Design), intended to certify building professionals using new materials and technologies to meet certain energy and environmental criteria. Since its launch earlier this year, this initiative has seen the accreditation of 19 000 people, including 9000 just last month. Of course, the movement still mainly concerns large structures, such as airports, or buildings that are traditionally heavy energy consumers, such as laboratories. The Natural Energy Laboratory in Hawaii, for example, uses seawater piping at 6 ° C to cool the building, condensing the pipes used for irrigation. For its part, Dallas Fort Worth Airport (Texas) has installed a tank of 22 million liters that can cool during the night, when the energy is the cheapest, the liquid air conditioning system.
Today, nearly 4% of new commercial buildings are built according to LEED guidelines.
