It is important to maintain indoor air and sanitary environments in waiting lounges, office rooms and medical wards of medical facilities. However, Japan has neither environmental nor hygiene law for medical facilities. In this study, the way of the maintenance of sanitary environments in medical facilities was examined. This part reported the measurement results of air temperature, relative humidity, airflow rate velocity, CO, CO_2, PM and formaldehyde concentrations in waiting lounges, office rooms and medical wards of 16 medical facilities in winter and summer. As a result, relative humidity values in most part of the rooms in winter were lower than 40%Rh. The CO_2 concentrations in the waiting lounges that had a lot of people were remarkably high. It can be presumed that the capacities of the ventilating rate were insufficient.
