Abstract

Thermal comfort is an adaptation of the human body, tends to accept environmental conditions. A person’s perception of thermal comfort is affected by air temperature, relative humidity, air velocity, mean radiant temperature, metabolic rate for work activities and clothing insulation. The demand for conducive high efficient air conditioned office building provides a thermally acceptable environment for human comfort and work that would in order to enable better work productivity performance and less occupant’s thermal dissatisfaction. In recognizing the significance of thermal comfort level to occupants, the main objective of the study is to determine the thermal environment perception among UTeM’s library staffs to the existing air conditioning system in their workplace by means of both qualitative and quantitative approaches. Determination of occupants’ perception on thermal comfort was obtained through observation and analysis method associated with a questionnaire on thermal comfort with respect to findings of objective measurement. Measurement of actual thermal comfort in work units was conducted by direct reading monitoring linked with thermal comfort instruments to determine the PMV and PPD values. Further to this study, it shown that the perception of library staffs on thermal environment in their workspace is at moderate level (more than 60%). The result indicated besides the substantial role of environmental factors, thermal adaptation and psychological parameters strongly affect human thermal comfort. Maintaining on AC system of the research building should be taken into consideration to produce good thermal environment.
