Survey on Thermal Environment in Residences in Surabaya, Indonesia: Use of Air Conditioner

Abstract

This paper reports the results of the survey in Indonesia on the consciousness of the residents towards the use of air conditioner. The questionnaire survey and measurements of the thermal environment were carried out. The higher the resident's income is, the more the percentage of the residents who feel the air conditioner is necessary. Once they start to use air conditioners, they will not quit using. When the air conditioner is used, the room temperature is from 24 to 30 degrees C., similar to that in Japan. The air conditioner is usually used around 14:00 and during sleeping time. This is similar to Naha's situation, a subtropical area in Japan. Also, the duration that the air conditioner is used is longer than that in Japan. The energy consumption for cooling is expected to increase in this area. © 2003, Architectural Institute of Japan. All rights reserved.
