Abstract
Simulation takes very important role in the filed of architecture and the magnificent efforts for the research and development have been made in many countries. Here some examples for the related activities are introduced, such as, IBPSA, International Building Performance Simulation Association, its Japan branch activities and the issues of the mailing list, and the attempt to establish a information center of thermal simulation in the framework of international researchers and its questionnaire. Also the status of the simulation tools is discussed and the necessity of the team that covers wide spread simulation related areas is pointed out.
