Household energy use and comfort cooling in Hong Kong

An overview of the energy use in the residential sector in Hong Kong during a 24-year period from 1975 to 1998 was carried out. There was a marked increase in the electricity use, particularly for comfort cooling. Air-conditioning was by far the single largest electricity end-user counting for about 40% of the total household energy use. To get some idea about the thermal condition and comfort cooling in the housing sector, a preliminary survey and site measurement of four households was conducted. An indoor climate analyser was used to measure the room air temperature, its corresponding relative humidity and air movement. This paper presents the findings and discusses its energy implications.
