The standard procedure used to analyze buildings that feature passive solar heating strategies is the load collector ratio (LCR) method. This procedure was developed by the Los Alamos National Laboratory between 1977 and 1984. As a result of the LCR method, one will obtain the solar savings fraction (SSF) of the input passive solar builDing The SSF is the most widely accepted metric used to evaluate the effectiveness of passive solar heated buildings. The SSF may be defined as the extent to which a building's passive solar feature(s) reduces a building's auxiliary heat requirement relative to a comparable building devoid of passive solar feature(s); This thesis compares nearly two-years of monitored data collected from five passive solar test rooms in Muncie, Indiana against the performance predicted by the LCR method as well as three other procedures related to passive solar heating analysis developed at the Los Alamos National Laboratory along with the LCR method; The conclusions of this thesis validate the LCR method with regard to projecting the SSF and auxiliary heat requirements for a range of passive solar heating strategies in a severe winter climate with predominantly cloudy sky conditions.
