It is the nation's most energy efficient sports venue and the world's first indoor sports facility to achieve LEED platinum certification for energy and resource efficiency. The complex is powered entirely by solar energy; water use by 45 percent and energy use by 30 percent. The first-of-its-kind displacement ventilation system delivers conditioned air directly beneath the seats, allowing fans to control temperature through a smartphone app. The arena's five-story aircraft hangar doors open to the city and the natural cooling breezes of the Sacramento Delta. ▲ Croton Water Filtration Plant New York, New York AECOM - Hazen and Sawyer (Joint Venture) New York, New York Situated under one of the nation's first public golf courses is a four-story 290 milliongallon-per-day water treatment plant that provides up to 30 percent of New York City's drinking water. Using deep-rock excavation and tunneling, the project team integrated a variety of advanced treatment systems, including stacked dissolved air filtration/flotation tanks. The largest plant of its kind in the world, the massive complex includes an impressive array of sustainability measures that minimize environmental impacts. The natural processes that control and filter 40 percent of the site's stormwater help the 9-acre Moshulo Golf Course also become one of the nation's largest green roofs. 22 ENGINEERING INC.
