Buildings are not only practical embodiments of design, but cultural icons, as well, which demonstrate ideas to society. We believe that to create positive change, action at the level of culture will have more profound and enduring effects than politics, money, or science. Each sustainably designed and constructed building is part of an effort leading to the goal of positive environmental impact for the building, its construction, and its use. A successful green building project results in a building that is an enduring and tangible monument to the feasibility of a sustainable society.
