Indoor environment conditions of a building are one of the concerned issues as most people usually spend 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 investigate the effect of indoor environmental quality (IEQ) towards occupants’ perception in engineering laboratories/workshops at Mechanical Engineering Laboratories Complex. Thermal comfort and indoor air quality analysis were conducted to evaluate the indoor environment quality of the laboratory/workshop. The 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 the questionnaire. Results show that air-conditioned machine workshop has temperature of 20.8°C which is not within the ASHRAE Standard-55 but still acceptable for occupants. Meanwhile, the thermal condition of non-air-conditioned welding workshop has not complied with the standard in terms of air temperature. In addition, result from occupant’s air odour perception indicates that air odour problem occurred in both case study areas. Based on the findings, indoor environment quality improvement measures are proposed to enhance the indoor environment quality (IEQ) level of the laboratory.
