| description | Recently, the effect of thermal sensation found to greatly impacted on the outcome or productivity of work within an area. Based on the thermal environment data, the air temperature and mean radiant temperature found to be in compliance with the standard stated, but the percentage rate of relative humidity revealed that were higher than standard, whereas the air velocity has reported were lower than standard. On the other hand, the results shown from relevant parameters in perceived thermal sensation, i.e. the level of coldness (air temperature and mean radiant temperature), the level of humidity (relative humidity) and the level of air freshness and air flow (air velocity), the major votes of these parameters were all lies within neutral thermal
comfort range and no either uncomfortable feel not health symptoms expressed. The Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfaction (PPD) deduced from the perceived thermal sensation votes were in compliance with the recommended standard as well.
Besides, the predictors or variables that found to impact on the perceived thermal sensation were localized sensation body part K (Feet), the level of air flow, the level of coldness, body part E (Back) and working alone factor. Out of these parameters, the feet presented the most significant influence on the perceived thermal sensation with respect to localized body sensation parameter, whereas the level of air flow and coldness have been revealed its significance to perceived thermal sensation in respect to thermal environmental parameters. Apart from that, the productivity of work was found to be significantly correlated to level of air freshness and air flow and level of coldness, which indicating it would be influenced by air temperature and air velocity. This directly implying of the perceived thermal sensation affected the rate of productivity towards students, and the most productive of task happened when the participants were in zero perceived thermal sensation, moderate level of coldness, moderate level of air freshness and air flow rate. |
