Hart and Wallach walk outside the Silo Eco-House, the first of Greensburg GreenTown's series of Eco-Homes. These buildings will be bed and breakfasts where eco-tourists can stay and experience green building. (The homes will be filled with small plaques explaining the different sustainable strategies, products, and fixtures used throughout the residence.) The Silo Eco-Home is the first B&B and also houses the Greensburg GreenTown headquarters.
