In 1984, energy guru and gadfly Amory Lovins made his home and established his globally significant consulting firm in a building that demonstrates his influential "soft path" approach to sustainability. The sun provides all the heat. Judicious choice of materials and meticulous construction retain it. Still operating with high performance today, this building sheds light on how to combine technical excellence with human feeling and values in a way that lasts. The story also illuminates the zig-zag American progress toward a sustainable society. The book unfolds these important topics in accessible detail.
