The Skyscraper Museum is devoted to the study of high-rise building, past, present, and future. The Museum explores tall buildings as objects of design, products of technology, sites of construction, investments in real estate, and places of work and residence. This site will look better in a browser that supports web standards, but it is accessible to any browser or Internet device.

This webcast and video archive documents the MIXED GREENS lecture series. The series features architects and engineers whose work in Europe, Asia, the U.S., and elsewhere demonstrates the leading edge in sustainable design and technology.

MIXED GREENS is presented in collaboration with the New York Academy of Sciences, and is hosted in one of New York's newest green towers, the LEED Platinum 7 World Trade Center.
