Study on performance of high reflectance paint for building.

Part4 Measurement of solar reflection and temperature for box specimens.

Abstract

In the previous report (part 1) we calculated solar reflection of the paint to examine an effect of the high reflectance paint and mechanism and reported that we measured a temperature change in the outdoors with various examination devices. In this report we installed all box specimens in the outdoor exposure site of the Building Research Institute and accumulated data during one year. We increased number of box specimens of other colors more than the previous report (part 1). We studied a correlation between the solar reflectance and the thermometry.
