Abstract

Optimum thermal comfort is vital in office building for work performance
improvement. The objective of this research is to determine the relationship between
thermal comfort parameters with PMV index value in naturally ventilated and
mechanically ventilated office building in tropical wet Savanna (India) and winter
Mediterranean climates (United Kingdom). The data is retrieved from the ASHRAE
global thermal comfort database II and had been analyzed by SPSS analysis software.
Total of 160 samples were retrieved and tested for the normality of the data,
correlation between thermal comfort parameters with PMV index value and linear
regression analysis. Air temperature, relative humidity, air velocity and clothing
insulation are the parameters that shows significantly correlate with PMV index
value. The difference between naturally ventilated office in India and United
Kingdom in optimum thermal comfort temperature is 3.11℃ while for mechanically
ventilated office, the difference optimum thermal comfort temperature is 3.42℃.
The optimum thermal comfort temperature between mechanically ventilated and
naturally ventilated office in India and United Kingdom are almost similar. In
conclusion, different thermal comfort parameters have different significant to the
PMV index value in different climates.
