Refocusing on Sustainability: Promoting Straw Bale Building for Government-Assisted, Self-Help Housing Programs in Utah and Abroad

Abstract

Central to this housing program evaluation and policy analysis is the need to clarify competing definitions of self-help housing and to delineate the role of straw bale building in creating more sustainable, subsidized housing programs. Straw bale home construction is shown to be achieved at a lower cost, with lower embodied carbon than conventional housing, yet the building technique is not widely practiced as part of government-assisted housing, internationally, nor among mutual self-help housing (MSHH) programs in the United States, due in part to limitations of code adoption. Community Rebuilds, a federally subsidized MSHH program in Moab, Utah, is compared to other self-help housing programs in the state and stands apart with current “living building” development. Interviews and survey results from Community Rebuilds staff, contractors, and homeowners provide qualitative insights regarding the value of social capital, and embodied carbon calculations were used to assess the sustainability of conventional versus natural building methods and materials. Results confirm the need for increasing straw bale building code adoption and the creation of more sustainable self-help housing options in the U.S. and abroad.
