The Boy Scouts of America / Trinity Works commissioned Volume Inc. to design an exhibition program that tells a sustainability story through the Sustainability Treehouse located at The Summit—an outdoor adventure center situated in the wilds of West Virginia. It is the permanent host of the BSA's Jamboree gatherings, held every four years with over 30,000 scouts in attendance. Designed by Mithun, the Net Zero structure meets the standards of the Living Building Challenge: all its power comes from the sun and the wind, all the necessary water is rain-captured, and all its waste is recycled.
