Abstract

A field study on thermal comfort and building energy has been carried out in one of main car manufacture in Malaysia. The objective of this study is to determine the thermal comfort include the purpose of air conditioning systems and natural ventilation among workers at Malaysian automotive industry. This study had combined three stations critical workstation to assembly work which consists of Door Check Assembly for coming model of Proton car and Stamping workstation also for producing component for a new Proton model.. The environment examined was the Air Temperature (°C), Relative Humidity (%) and Air Velocity (m/s) of the surrounding workstation area. The environmental factors were measured using Babuc apparatus, which is capable to measure simultaneously those mentioned environmental factors. The time series data of fluctuating level of factors were plotted to identify the significant changes of factors. Then thermal comfort of the workers were assessed by using ASHRAE Thermal sensation scale by using Predicted Mean Vote (PMV) which has been proposed earlier by Fanger (1970). Further Predicted percentage dissatisfied (PPD) is used to estimate the thermal comfort satisfaction of the occupant. Finally the PPD versus PMV were plotted to present the thermal comfort scenario of workers involved in related workstation. The study reveals that 31% of the workers populations at the workstation are likely to be satisfied with thermal comfort at this station.
