Experiment on Surface Temperature Thermal Effect of Ordinary Paint Colors on The Building Facade Surface

摘要

Based on spectrum measurement and analysis, combined with experimental result of surface temperature pattern on actual painted wall, investigated the relationship between paints color and solar reflectivitysur, face temperature. Results show that, in the case of direct sunlight, reflectivity of paints has a crucial impact to surface temperature. Using a light-colored paint can get a lower surface temperature on same wall. This impact is more remarkable under strong sunlight during 10-14am, R2=0.99. The conclusions support to provide the technical parameters for urban thermal environment risk by Remote Sensing technology.
