AbstractPrevious research has shown that stratified ventilation systems (UFAD and DV) work well for regions where buildings require year-round cooling; however there are a growing number of buildings using this approach in Canada, where buildings require heating during winter months. This paper presents results from two field studies conducted in a school equipped with a combination of displacement ventilation and radiant heating system. The results show that the measured contaminant removal effectiveness is better than that predicted in previous studies for heating conditions. In addition, key predictors of thermal comfort are also generally within limits set by ASHRAE standards.
