Energy Consumption and Air-Conditioning Usage in Residential Buildings of Malaysia

Abstract

This study provides the detailed information on household energy consumption in residential buildings of Malaysia. A survey was conducted in Johor Bahru in 2009 to analyze electricity consumption due to airconditioning. The results showed that the air-conditioner ownership was 65% and its daily usage time was 6 hours on average. The yearly electricity consumption caused by air-conditioning recorded the largest amount among household appliances. Another survey was carried out in 2004 to reveal the detailed usage patterns of cooling appliances in the same housing estates. The results showed that most of the air-conditioner owners have installed them in bedrooms and operate them during the whole night for sleeping. 61 【Report】 Journal of International Development and Cooperation, Vol.17, No.3, 2011, pp. 61-69 Energy Consumption and Air-Conditioning Usage in Residential Buildings of Malaysia Tetsu KUBOTA Associate Professor Graduate School for International Development and Cooperation, Hiroshima University 1-5-1 Kagamiyama, Higashi-Hiroshima, Hiroshima 739-8529, Japan E-mail: tetsu@hiroshima-u.ac.jp Sangwoo JEONG Graduate Student Graduate School for International Development and Cooperation, Hiroshima University 1-5-1 Kagamiyama, Higashi-Hiroshima, Hiroshima 739-8529, Japan Doris Hooi Chyee TOE Graduate Student Graduate School for International Development and Cooperation, Hiroshima University 1-5-1 Kagamiyama, Higashi-Hiroshima, Hiroshima 739-8529, Japan Tutor Faculty of Built Environment, Universiti Teknologi Malaysia 81310 UTM, Skudai, Johor, Malaysia Dilshan Remaz OSSEN Senior Lecturer Faculty of Built Environment, Universiti Teknologi Malaysia 81310 UTM, Skudai, Johor, Malaysia 62 Tetsu KUBOTA, Sangwoo JEONG, Doris Hooi Chyee TOE and Dilshan Remaz OSSEN
