The performance value of cool painting is usually indicated by the solar reflectivity that is measured by spectrometer in the laboratory. It is not easy to measure insolation reflectivity of a painted surface accurately, for the reflectivity is influenced by the surroundings. In this study, it was examined that a method for insolation reflectivity measurement of horizontal cool painting surface using white and black board whose performance was known, and this validity was confirmed. It was found that the performance value using this method was able to be predicted within the error of approximately ±0.05. The fluctuation of the insolation reflectivity by the incident angle of the sun light was less influenced on prediction accuracy, if the measurement was done without a break.
