Each year, the National Building Museum presents an ambitious exhibition schedule that engages visitors with diverse topics and stimulating ideas. Fiscal year 2003 was no different. The Museum opened ten exhibitions, starting with a look at the infrastructure of our country and how it supports our lifestyles, and ending with an examination of how elevators, escalators, and moving sidewalks have shaped our world as we know it. In between, the Museum offered the public a big slice of “green architecture,” also referred to as environmentally-sensitive or sustainable architecture, among other exciting shows.
