The building, which had been an abandoned 1940s grocery store, was refurbished for less than the cost of new construction. Its Earth-toned colors save 80 percent on energy, and solar panels meet almost half of office electrical demands. About 92 percent of deconstruction waste was recycled or reused, and 25 percent of materials came from sources within 500 miles (805 km) of Billings. Other green features include rooftop clerestories, cooling with outside air, radiant-floor heating, exterior rigid insulation, composting toilets and waterwise plantings.
