The National Building Museum’s exhibit, “The Green House: New Directions in Sustainable Architecture and Design,” has been the most successful in its history, and will remain open until June 24.

The exhibit demonstrates how small decisions-such as what kinds of light bulbs, bamboo, or paint to use-can have significant environmental, health, and economic impacts. The Green House is the first exhibition to explore in a comprehensive way the growing mandate for green design in houses and apartments.

Featuring an international survey of 20 contemporary residences plus a full-size, furnished version of architect Michelle Kaufmann’s “Glidehouse,” and a materials resource room with 60 different green materials from carpets to countertops on display, the exhibit illustrates the inherent compatibility of environmental priorities, comfort, and aesthetics. Since its opening last May, the exhibit been visited by more than 100,000 people.

Upcoming events include a May 30th symposium entitled Sustainable Design: New Directions in Affordable Housing that will explore how government, business, and the nonprofit sectors can work together to achieve sustainable and healthier affordable housing options for Americans.
