A web-based questionnaire survey on residents' awareness of environmental adjustment behaviors among residents of houses in dense areas are conducted. The results show that environmental control behaviors aren’t effectively utilized on the first floor of detached houses due to concerns about security and privacy. In contrast, about 65% of detached houses built in dense areas have living rooms on the second or third floor as a way to secure sunlight and openness. Also, there is less concern about security in multi-family dwellings. This suggests the interest and potential of residents’ environmental adjustment behaviors to make the thermal environment more comfortable.
