In previous papers, the authors reported on a simplified model for predicting vertical temperature distribution and a mathematical model for unsteady state heat analysis of a large space. We verified that these models could be used to make accurate predictions by comparing results produced using the models with the results of laboratory tests. In this paper, we apply these models to an existing large space and compare the results of calculations with measured values. An atrium building was chosen as the subject space because vertical temperature differences tend to be large, especially in summer, and the building was suitable for confirming the accuracy of predictions made with our proposed models.
