INTERACTIONS BETWEEN THERMAL AND ACOUSTIC COMFORT OF A MIXED-MODE VENTILATION BUILDING IN SINGAPORE

Abstract

Most studies conducted in controlled environmental setting and/or only focus on single effect, the present study on human comfort has highlighted a lack of research on how combined effects of indoor environmental quality affects human overall comfort. As a result, there is a paucity of understanding the interrelationships of different physio socio-psychological aspects on human comfort and the manifestation of their contextual interactions. In that direction, this research paper uses data from a testbed experiment conducted in NUS, School of Design and Environment Building (SDE1) led by Assistant Professor Adrian Chong and his multidisciplinary team. To determine how thermal and acoustic perception interactions affect occupant comfort in the mixed-mode building, measurements of indoor environmental quality parameters and results from comfort survey are used. The key findings present that thermal sensation does not affect acoustic sensation and vice versa, despite being in different mode of operations in the mixed mode building. The interactions of thermal comfort and acoustic comfort is not significant based on the data graphs generated using the results of comfort survey.
