An artist's rendition of the planned Bank of America headquarters building in midtown Manhattan. It will use "environmental technologies to promote the health and productivity of tenants, reduce waste and assure environmental sustainability," according to developer The Durst Organization and Cook+Fox Architects.

Higher ceilings and translucent insulating glass in floor-to-ceiling windows permit maximum daylight in interior spaces, optimal views and energy efficiency.

The 54-story skyscraper special features include a double wall to dissipate heat; carbon dioxide monitors to control the flow of fresh air; and a gray-water system to reuse all rainwater and wastewater.

An under-floor displacement air ventilation system and floor-by-floor air handling units allow for individual floor control and more even, efficient and healthy heating and cooling.
