Although it is important to implement prevention of infection for COVID-19, there is rarely information on the current ventilation conditions at the actual research and education sites. The purpose of this study is to investigate the actual ventilation conditions in lecture rooms, meeting rooms, and faculty or student rooms in the graduate school where the authors are, and discuss necessary measures to continue education and research activities based on the results. According to the survey of ventilation, there were some rooms which need to increase the volume of ventilation, on the other hand, it was difficult to adopt natural ventilation for the rooms. As a case study, CFD calculation was performed to elucidate the effect of installing an air purifier in a meeting room to improve to ventilation conditions. From these survey and analysis, problems of ventilation in research activities place were specified, potential risks and infection prevention method in ventilation were discussed in this study.
