Fig. 7(a-d) are surface temperature comparison of each wall of the buildings with the High Solar
Refleciive paint, conventional paint coaiing and uncoated. The High Solar Reflective Paint coated
building is a little less wall surface temperature than the conventional paint coated building.
Especia"lly, the roof surface temperature of the High Solar Reflective Paint coating building is less than
the conventional paint coating building 2-4'C. When compare with the uncoated building, the wall
surface temperature of the unioated is higher than the High Solar Reflective Paint coating building.
The highesi temperatures of the roof during 11 am to 2 pm are about 45-47 oC, more than the
temperiture of heat insulated coating building about 5-7 oC. At the eastern wall of building, the
highest temperature s are 42-43 oC in the morning, more than the temperature of heat insulated coating
tultaiog about 10 "C. This result is caused by the uncoated building has low sunlight reflect
perfo.riarrc", so, the almost heat energy from the sunlight can pass through the inside. The coating
with the higher values of solar reflectance demonstrated the lower surface temperature. We can
therefore conclude that the main factor affecting the thermal performance of samples during the day is
their solar reflectance. The High Solar Reflective Paint coated building can reflect abott 69-73oh of
sunlight energy, as shows in Flg. 6, when it incidents into the building, as well emit the heat. With
theseireasonr, th. urr".uge room and roof surface temperatures, both inside and outside, of the coated
building is less than the conventional paint coated and uncoated.
