Through work done in this course, the community has benefited in numerous ways. For example, Habitat for Humanity has been aided through the development of instructional guides that provide volunteers with instructions on how to apply roofing, siding, drywall and trim, as well as guides on how to properly work with various tools. Habitat has also received help in identifying the most economical construction methods for houses in Dane County, through a comparative study of one- and two-story houses focusing on basements, frost walls or shallow frost-protected foundations. Energy analyses have provided Habitat with a basis to evaluate the long-term costs of various construction methods. The City of Madison has also partnered with students in this course, with the positive result of the city receiving a complete "sustainability" analysis for the Monroe Street library building. For this project, student design teams evaluated the existing building and developed energy models that were verified by comparison with actual monthly utility costs, then the models were used to evaluate a series of design changes that were provided in a proposal for the city. More recently, student teams were involved in working with Hillel to develop specifications for monitoring the new Hillel center being built on campus through devices installed during construction that will continuously measure the energy used in the building.
