Optimization of Temperature and Relative Humidity with Maximum Oxygen Uptake (VO2max) and Heart Rate (HR) by Using Response Surface Methodology (RSM)

Abstract

In tropical developing countries, the workers in the construction industriesare facing with high risk of thermal stress. As global temperature is estimated to be increased year by years thus constituted significant negative impacts to the workers at construction industry in Malaysia. Therefore the objective of this research paper is to highlight the findings on the perceptions of Malaysian construction workers towards the significant impact of thermal to their life. Utilizing structured ques tionnaire survey, there were 292 respondents response were gathered throughout Malaysian construction sector. The method of data collection used in this study is through online surveys by using Google Forms. The data have been analyzed through Structural Equation Modelling (SEM) and by using SPSS software Version 24 as well as Partial Least Squares (PLS) analysis techniques using the SmartPLS 3.0 software
