Green Roofs for Historic Buildings: Case Study of the Bar BC Dude Ranch at Grand Teton National Park
Historic Preservation and Conservation
This thesis proposes to explore historic sod roofs as a precedent for green roof construction through the analysis of surviving examples at Bar BC Dude Ranch in Grand Teton National Park, WY in order to suggest new adaptations to historical usage. The ultimate goal will be to study the original and current roofing techniques to determine a method that will allow historical interpretation of the structures while improving roof and building maintenance and overall sustainability. This thesis will investigate the history of sod roofs, especially in relation to log building in the American West and the design of modern green roof construction as a means from which recommendations for the application of new sod roofs may be designed, tested, and applied. The Bar BC Dude Ranch at Grand Teton National Park will serve as a case study to better understand existing historic sod roof construction, why such roofs fail, to evaluate deterioration and sod roof performance, as well as to suggest a new design for the extant structures that may ensure their conservation and interpretation.
