This laboratory makes researches to understand, predict and control urban and building environment as a complex system. The main research interest is the wind, air and thermal environment. We have been developing monitoring and simulation technologies for each environmental element, and also studying environmental control technology that integrates measurement and prediction techniques by mathematical/statistical methods. Current main research themes are: (1) elucidation of fluid phenomena in the environment, (2) dispersion modeling of air pollutants, (3) development of monitoring methods of the urban environment and (4) development of inverse analysis methods of environmental parameters.
