In previous papers, we proposed a thermal environment simulation method that uses heat response. The utilization of the heat response reduces the calculation time for integrating CFD (Computational Fluid Dynamics) analysis into the thermal environment simulation. The heat response is calculated under the assumption that the heat transport phenomena can be fixed on a static flow field. Therefore, there are some discussions on the calculation accuracy for simulations with airflow change. We carried out measurements using a 1/4-scale office model to check the range of applications of our method. These studies aim an integration of the comprehensive heat transport by airflow, which creates a three dimensional temperature distribution. The measurement results indicate that around 20% of change in supply airflow does not affect the comprehensive phenomena of heat transport. This explains the range of applications of our proposed method. Moreover, we proposed a correction method based on purging flow rate to increase the calculation accuracy when the supply flow rate is changed.
