| 總結: | Urban Heat Island (UHI) phenomenon leads to the increasing of urban environment
temperature and higher human thermal discomfort level. The study of the thermal
manikin that used to evaluate human discomfort based on thermal comfort indices is
very limited. The purpose of this study is to investigate the suitability of porous
material such as red clay, white clay and plaster as the potential manikin for outdoor
thermal comfort index. Porous materials such as red clay, white clay and plaster have
been selected to determine its evaporation rate by correlating it with evaporation rate
of human sweat. The surface temperature of porous material was obtained through
data logger and the data was correlated with human thermal perception which was
designed based on the ASHRAE standard 55 for comfort evaluation. The last
objectives of the study was to correlate thermal comfort indices with porous material
surface temperature in order to identify suitable porous material for thermal comfort
evaluation. This study used two types of statistical analysis methods which were
descriptive analysis and bivariate analysis (Pearson correlation). The result shows
that, red clay has a good correlation compared to other porous materials in terms of
human sweat evaporation rate and human thermal perception which indicated r =
0.583 and r = 0.685 respectively with p<0.01. Furthermore, Heat Index (HI) had a
strong relationship and statistically significant with all the tested porous material
surface temperature. More precisely, HI had a strong relationship with red clay
surface temperature which indicated r = 0.733 with p<0.01. Based on this, it revealed
that red clay shows a consistent correlation to all parameter compared to other porous
materials and this can be concluded that red clay can be the potential manikin for
thermal comfort evaluation. The suitable material selection in this study is believed
to help humans have a better understanding of thermal comfort assessment. |
