At Lake Mohave, Nevada, the Cottonwood Cove Marina & Resort takes one step further toward ecological sustainability as the first-ever floating building to seek LEED certification. Designed by Carlson Studio Architecture, the structure’s custom fabricated dock will support a houseboat rental business and an engine repair shop. The marina will house the Lake Mead National Recreation Area resort’s office of operations and provide dry storage for its clientele’s boats. The Florida-based architecture firm hopes that the marina will receive Gold level LEED certification. Committed to ecological sustainability and innovation, Carlson Studio Architecture implemented an energy-efficient design. The structure’s SIPS walls and roof protects the interior from direct sunlight and are lined with Photovoltaic panels. The building’s insulated shell and general orientation optimize its energy consumption and costs. Its stucco exterior is composed of reused tires; the decking of rice hulls and recycled plastic. The marina celebrated its LEED registration status at a public event on Monday, June 6th.
