OMAHA, Neb. (AP) -- TD Ameritrade's new headquarters tower in Omaha has been recognized for its efficient design that includes numerous features to conserve energy.
The $250 million, 12-story tower opened last year in west Omaha. TD Ameritrade said Tuesday the U.S. Green Building Council gave the building its highest platinum rating for Leadership in Energy and Environmental Design.
The building includes sensors to turn off LED lighting when workers aren't at their desk or if sunlight is available, and rainwater is captured and reused in toilets.
There are also solar panels on the tower's roof, a rooftop garden on another part of the building and four wind turbines.
TD Ameritrade officials say the environmental features cost more up front, but they will pay off over time because the building uses significantly less energy.
