Waseda University: Human body thermal comfort
Waseda University users Cradle CFD to simulate airflow in building spaces and predict thermal comfort, including human body temperature responses.
One basic application of Computation Fluid Dynamics (CFD) is to simulate airflow in building spaces. The outputs from CFD can be used to ensure that air flow rate, velocities, and patterns meet environmental standards for human comfort.
Taking a step further, CFD has recently been used to predict and evaluate thermal comfort using thermo‑regulation models of the human body. In these simulations, the airflow in the environment is still calculated as before, but the human body, as a separate thermal system, is coupled to the airflow calculation. This enables the calculation of the actual human body temperatures in response to the airflow and environmental thermal conditions, providing a much greater understanding about human comfort. SC/Tetra contains a fully coupled human body thermo‑regulation model. It simulates office environments, car interiors, and air pollution.
Shin‑ichi Tanabe, Professor, Department of Architecture in the School of Creative Science and Engineering at Waseda University, developed the thermo‑regulation model in SC/Tetra. It is called the JOS (Joint System) thermo‑regulation model.
