Abstract: According to previous work, preference is one major factor influencing occupants' behaviour. This paper aims at identifying the magnitude preference on the exergy consumption pattern within a built environment. The comparison is made between one group claiming to like sleeping in air-conditioned spaces and the other claiming to dislike it. In conclusion, the exergy analysis showed that at the individual level, preference accounts for an exergy consumption rate up to 15% higher and that, at the community level, the exergy consumption rate of those preferring the AC-unit use is up to four times higher than that of the others'.

Keywords: exergy consumption patterns; field measurements; occupant behaviour; occupant preference; logistics analysis; air conditioning usage; built environment; exergy analysis; air conditioning units; buildings.
