(57) [Summary] [Problem] To suppress the temperature rise inside a building without relying on a large-scale construction method using a conventional heat insulation method, And a method capable of improving the durability in the outdoors. A method of applying a heat-shielding color paint to a siding material, wherein the heat-shielding color paint is 780. A white paint having a solar reflectance of 50% or more in a wavelength range of ２2100 nm, a blue paint having a solar reflectance of 20% or more in a wavelength range of 780 to 2100 nm, A red paint having a solar reflectance of 30% or more in a wavelength range of 2100 nm, a green paint having a solar reflectance of 20% or more in a wavelength range of 780 to 2100 nm, 780-2. Two or more primary color paints selected from the group consisting of a yellow paint having a solar reflectance of 40% or more in a wavelength range of 100 nm and a black paint having a solar reflectance of 8% or more in a wavelength range of 780 to 2100 nm. And a method for applying a heat-shielding color paint prepared by combining the above. |
