The design of energy efficient homes has been my avocation si nee leaving professional architectural practice in 1980. It has been a unique opportunity to be in the situation where the time is available for an extensive post occupancy evaluation of these homes. I have not intended that these residential projects be judged by current 11 architectural11 theory, for they were designed to avoid architectural gymnastics and fit into the Oklahoma streetscape. If the projects are to be evaluated on the basis of energy efficiency, thermal comfort, and satisfaction provided the owners, there is evidence of success. The owners of the homes were their own interior designers. Five homes designed by the researcher are evaluated in simple, easily understandable terms, to establish how efficient they really are and, more importantly, to see if the homes helped disseminate the virtues and advantages of passive solar residential design to the persons that have worked on or visited the homes.
