Large auditoriums with stairs produce inhomogeneous vertical temperature profiles, which cause uncomfortable thermal condition in the occupant zone・ The indoor thermal environment about an auditorium with a space of 1950m^3 were investigated to evaluate the indoor climate in summer and winter. Form field measurements, the following conclusions were obtained. In winter, air temperature at the ceiling level was 13 centigrade higher than that at the floor level. Also, the temperature at the entrance level, equivalent to 35 centigrade, was 7.7 centigrade higher than that at the level of teacher's desk. Therefore, the thermal comfort in winter was evaluated too warm by the PMV measurement. This large temperature differences occurred due to the stagnant warm air in the ceiling zone and the cold stream flowing down form the blackboard to the floor. It was concluded that mixing fans capable of recirculating the stagnant air had to be operated to eliminate the inhomogeneous temperature differences. In summer, homogeneous temperature distribution was obtained vertically and horizontally. The thermal environment was evaluated slightly cool.
