Thermal performance measures during the 1980-81 heating season of 86 residences in the Northeast US were estimated on the basis of audit information. Analysis utilizing fuel bills, ASHRAE-type heat loss coefficient estimates based on auditor measured parameters, and degree-day data yielded the following: an average total space heating load of 98 kJ per square meter per degree-C day (4.8 Btu per square foot per degree-F day), a solar savings fraction of 27%, and a solar heating fraction of 50%. The average auxiliary heating prediction based on the SLR method (as modified in the FCHART/SLR computer program) is 13% higher than the average, audit-estimated, actual auxiliary load of 42 GJ (40 MMBtu). On a case by case basis, considerable random differences are exhibited between predicted and estimated actual thermal performance measures.
