Bill Chaleff exposes the flaws with current urban planning and the costly effects as well as the toll on society's way of life. Bill Chaleff has designed over 400 energy-efficient buildings since he began his practice on Long Island in 1974. These solar and underground structures – the first on Long Island - have been built using state of the art construction methods and materials and have integrated thermal system engineering with structural engineering and architectural design. Bill is the developer of air-floor construction, which has been integrated into over 150 buildings over a period of 40 years. His firm won a New York State engineering award for their Tuckahoe School addition.

Bill has been guest lecturer at U.C. Berkeley and at R.I.S.D. and New York Tech Architectural Schools. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
