Measured performance of 50 passive solar residences in the United States

The thermal performance of 50 passive solar residences in a variety of U.S. locations is summarized. These buildings were monitored as part of the Solar Energy Research Institute (SERI) Residential Class B Passive Solar Performance Monitoring Program. The monitoring and performance evaluation methods are described and the overall heating season performance of the buildings are presented in graphical form. The validity of extrapolating the data generated to passive solar buildings in general is discussed.
