AB - Indoor climate has a three-dimensional spatial distribution caused by three-dimensional airflow. To obtain the accurate knowledge of building performance, it is demanded to integrate the spatial distribution into building simulations. Thus, CFD analysis is necessary in design process. However, usually only a few case of CFD could be executable Unit Pulse q=1W F j : Pulse Generation Point i : Calculation Point N : Step where the rate of decline becomes constant j F n : thermal response factor [ºC/W] in real design process, because of the large computational load. The main subject of this study is 0 ΔT 2ΔT nΔT t NΔT the development of a method; how to extract heat transport phenomena in rooms from such limited CFD analyses, and how to integrate the data into a nodal analysis. Using the method, we can calculate indoor environment, including the spatial distribution of temperature with a very light computational load and with almost the same degree of precision as CFD simulation.
