In 2013, the Boy Scouts of America made conservation a stronger focus of the organization by introducing a new sustainability merit badge and opening an educational center in the 10,600-acre Summit Bechtel Reserve in West Virginia (http://www.summitblog.org/). Using the Living Building Challenge as a guide (a rigorous set of construction standards similar to LEED), Seattle-based architecture firm Mithun spearheaded a multidisciplinary team to create a tree house that would turn lessons into an adventure. Sited on a former coal mine, the building features a locally made prefabricated steel megastructure, FSC-certified black locust wood housing, a photovoltaic array, a wind turbine, and a rainwater catchment system. Staengl Engineering provided mechanical design services and energy analysis for the project. http://www.dwell.com/finishing-touch/article/sustainable-educational-center-boy-scouts-america.
