Abstract
Physical parameter of the windows of 24 apartment of the students in Kyoto city were measured. Questionnaire about importance and satisfaction with windows were done on the 248 students. The results showed that the correlation between "openness", "existence of daylight" and physical parameters were not so large. The major factors which students need for window were "daylight", "ventilation", "lack of noise", "comfortable temperature" and "openness". The largest factor obtained by factor analysis was "continuity to the outside". The importance of "observe the weather", "feel time lapse" whose loading scores were large on the largest factor were small.
