Solar energyIn 1957, the Solar Building (Bridgers and Paxton Office Building), Albuquerque NM, was the first commercial building to be heated by the sun's energy. It was subsequently listed in the National Register of Historic Places for its "exceptional importance," in the area of engineering because it was an early solar-heated commercial building, the equipment for which survived largely intact. It was constructed when active solar-energy systems were still considered experimental. The site is privately owned, at 213 Truman St., NE., Albuquerque, NM. The architectural design was provided by Wright and Stanley. |
