Although smart homes have been much developed in China, smart homes has been mainly towards the adoption of new technologies. There is little development of smart homes to consider and meet residents` needs in China. This study investigated residents` living in apartments in China using a questionnaire to identify their demands on smart homes. Through the survey, this study analyzed residents` space use patterns, daily living patterns etc. according to their ages. The results implied that there are significant differences in the use of spaces and demands on daily living within apartments. The results of this study should be considered for the development of smart homes in future. For example, it might be easier for people in the 20`s to adopt Internet of Things (IoT) and environmental control systems compared to other age groups because most of them in the 20`s use smart phones effectively without difficulties. In case of people in their 50`s who stay home more times for taking a rest and eating meals compared to other age groups, smart technologies should be applied to support their health care and works in housings. This research emphasizing residents` experiences could be basis for the development of smart homes in China.
