In large enclosures such as gymnasiums, it is difficult to control air temperature in the occupied zone comfortable in heating condition. There are two main reasons why air temperature in an occupied area is not increased efficiently in large enclosures. 1) A hot supplied air goes up and stays upper area due to buoyancy and it takes long time to reach lower occupied area. 2) Heat capacity of building structure disturbs to increase air temperature and cold air stays lower area. In this paper, the field measurement is presented in which the under floor return system is applied to the gymnasium to resolve these problems. Macroscopic simulation and CFD simulation are also demonstrated and the details of temperature distributions and during warming up are discussed.
