Abstract

Indoor environment conditions of a building are one of the concerned issues as people usually spend most of their time inside the buildings. Poor indoor environmental conditions can influence human health in terms of physiological, perceptual and emotional as well. The main objective of this study is to determine the indoor environment condition of engineering laboratories in Mechanical Engineering Laboratories Complex. Thermal comfort analysis and indoor air quality analysis were conducted to evaluate the indoor environment quality of the laboratories. Analysis consists of physical measurement and subjective measurement. Physical measurements were conducted with occupancy and no occupancy condition while subjective measurement was carried out through questionnaire. Results show that air-conditioned machine workshop has temperature of 20.8℃ which is not within the MS 1525:2014 standard but still acceptable by occupants. Meanwhile, the thermal condition of non-air conditioned welding workshop is not complied with ASHRAE Standard 55:2010 in terms of air temperature, PMV and PPD index. In addition, result from occupant’s air odor perception indicates that air odor problem occurred in both case study areas. Based on the findings, indoor environment quality improvement measures are proposed to enhance the IEQ level of the laboratory.
