Rodwin Architecture and Skycastle Homes Location: Boulder, Colorado, United States This sunny, simple, contemporary Prairie-style home achieves HERS 45 with no renewables. Silver Mesa Ranch blends quietly into the surrounding hills, and takes full advantage of the stunning views, carefully shielding out neighboring development and capturing foothill and plains panoramas. It includes passive solar design, an off-the-shelf mechanical systems, HRV, high performance windows, and a uniquely camouflaged rooftop Colorado evaporative cooler (in the chimney).
