A college specializing in engineering has usually laboratories, exercise rooms, drawing rooms and the like and these rooms have functions and objects which a college specializing in liberal art does never have. In the former, research rooms are used in various manners. As a result, the internal environment and usage of each room cannot be determined only from the name of the room and the faculty to which the room belongs. This study has investigated all rooms of Kogakuin University as an example of colleges specializing in engineering, comparatively examined these rooms by faculty and use(research rooms,laboratories) and conducted classifications of study items and individual rooms. In the classification according to the whole study items, the classification standards of "good or bat" of the envrionment and "active or inactive" of the work were made clear and in the classification according to the study items about the internal environment and equipped machines and implements of research rooms and laboratories the classification standards of "good or bad" of the environment and "chemical work or mechanical work" were clarified.
