Abstract [en]

Good sleeping environment is important to guarantee person’s health and performance. How to create comfortable and healthy sleeping environment with less energy use is worth exploring. Findings, based on one questionnaire survey on sleeping environment conditioned by different cooling modes (split system air conditioning unit, different kinds of electrical fans or purely natural ventilation), were reported. The study aimed to investigate human factors such as bedding and sleepwear use, using habits of different cooling devices, and human responses to thermal environment and air quality created by different cooling modes. 290 effective questionnaires were collected between June 2013 and May 2014, which were statistically analyzed. The results showed that most of the respondents prefer to use air conditioner for certain number of hours with relatively low temperature settings especially for respondents living below 5th floor. For respondents living above 10th floor, the number of hours using electrical fan or purely natural ventilation increase and their perceived air quality improve obviously. Respondents, who work outdoors during daytime, use less time for air conditioner with relatively high temperature setting. Elder respondents above 55 seldom use air conditioner.
