“…For example, the surface temperature of human body and room walls can cause the increase of radiation temperature [26]. The orientation and surface treatment of window glazing [27] and the occupant behaviour [28] also have important effects on energy performance and thermal balance of thermal comfort level.…”

Indoor thermal environment of a 3-D ventilated room was studied by computational fluid dynamics to understand correlations between heat generation, ventilation velocity and thermal sensation indices. The existence of a thermal occupant was found to produce thermal plume approx stronger in magnitude than that from an unoccupied room. With second thermal occupant, there has further temperature increase of maximum , equivalent to an increase of PPD value by , for which occupants would normally feel uncomfortable.Thus, an increased flow ventilation rate ( ) would be required, in order to keep the same thermal comfort level of the room.

“…The reference to 'mind' indicates that it is essentially a subjective term; however, there has been extensive research in this area and a number of indices exist which can be used to assess environments for thermal comfort [7,15] . Atmaca [11] suggested three conditions for comfort; these are that the body is in heat balance and that the mean skin temperature and sweat rate are within limits required for comfort. Conditions required for heat balance can be derived from a heat balance equation.…”

“…It is considered that satisfying 80 of occupant is good: That is, PPD less than 20% is good [37] . Without ventilation, a building's occupants will first be troubled by adores and other possible contaminants and heat [11] . When we discuss about heat, actually automatically discuss about thermal comfort building's occupant.…”

“…The building envelopes are the main factors of building energy efficiency and human thermal comfort, as they represent a skin of the buildings body [11] . The building whose envelops include suitable insulation has little internal heat gains and outside gains from solar radiation and in such a situation, the interior surface temperature of the building walls helps in defending from outside environmental conditions.…”

Problem statement:The objective of this study was to determine the dominance effects of environmental factors such as Illuminance (lux), relative humidity (%) and WBGT (°C) on the operators' productivity at Malaysian automotive industry. Approach: One automotive parts assembly factory had been chosen as a subject for the study. The subjects were workers at the assembly section of the factory. The environment examined was the Illuminance (lux), relative humidity (%) and WBGT (°C) of the surrounding workstation area. Two sets of representative data including the Illuminance, relative humidity (%) and WBGT (°C) level and production rate were collected during the study. All the data was measured using Babuc apparatus which is capable to measure simultaneously those mentioned environmental factors. The time series data of fluctuating level of environmental were plotted to identify the significant changes of factors. Then Taguchi Method was being utilized to find the sequence of dominance factors that contributed to the productivity of operator at the specified production workstation. From there, optimum level for the three factors will be determine for optimum productivity. Further multiple linear regressions were employed to obtain the equation model in order to represent the relationship of these environmental factors towards productivity. Results: the thermal comfort assessments of this station which was the scale PMV was 2 and PPD is 79% ware likely to be satisfied by the worker. Conclusion: The study revealed that the dominant factor contribute to the productivity at the body assembly production line is WBGT and Illuminance whereas the empirical finding was closely related to the perception study by survey questionnaire distribution.
