This project investigated the accuracy of ASHRAE Standard 152P, Method of Test for Determining the Design and Seasonal Efficiencies of Residential Thermal Distribu-tion Systems, in predicting the distribution efficiencies of five different configurations of a single residential warm-air thermal distribution system. Benchmark values for actual design and seasonal distribution efficiencies were obtained through independent field measurements. It was found that Standard 152P predicted distribution efficiencies 11 percent-age points less on average than the benchmark values and that Standard 152P predicted a significant change in distribution efficiency each time the ducts were reconfigured, while the benchmark values were virtually unchanged through the first four duct configurations.
