Field measurements were taken to determine the thermal comfort conditions in the conditioned space of a residence using a conventional forced-air and high-velocity distribution systems. This assessment included whole-house testing. During the cooling season, measurements were made to evaluate the thermal comfort in the space by evaluating the air and radiant temperatures, relative humidity, and airflow rate. Results revealed that both systems maintain the majority of the house at comfortable conditions according to the predicted mean volt (PMV) and predicted percent dissatisfied (PPD) values, but higher comfort percentages were obtained using the high velocity distribution system. The conventional system register location had a significant effect on the comfort in the conditioned space.
