Five privately owned homes and two university owned homes were examined by architecture students in order to formulate design alternatives to fit the houses with solar collection, storage, and control devices for supplementing domestic space and/or water heating. General principles advanced include why energy conservation and solar retrofitting are important today, and conservation in existing homes as a response to local climatic opportunities, reevaluated assumptions of comfort, general domestic habits, architectural response, and the resulting energy use. Specific alternatives include a description of each home, the owners, their existing comfort requirements, energy needs, and a range of architectural and domestic lifestyle alternatives for energy conservation and solar retrofitting.
