The First Living Building Challenge Certified Projects

The Tyson Research Center, Washington University's satellite campus for environmental research and education, provides a landscape-scale experimental venue for studies on ecosystem sustainability, a 2,000-acre outdoor laboratory, and classroom facilities. It is one of the first projects to achieve Living Building certification.

Another of the first projects to achieve Living Building certification, the Omega Center for Sustainable Living on the campus of the Omega Institute for Holistic Studies in the Hudson Valley serves as a biologically based wastewater processing plant, functioning classroom, and yoga studio.

Surrounded by its own food-producing gardens, the Eco-Sense residence houses six people in sustainable style and comfort.

Naturally shaped earthen walls and floors inside the home are finished with a smooth lime-based plaster, as illustrated by the family's combined living room and dining room off the kitchen. Built-in benches and niches along the walls provide seating and storage or display space.


The Eco-Sense home was constructed of traditional cob: a combination of clay, sand, and straw, clad in a lime-based plaster. According to the owners, it is the first code-approved, seismically engineered, insulated cob house in North America.
