Solar reflectance of glass
WebApr 18, 2024 · The solar energy transmittance of an uncoated clear glass is around 0.80 (80%) and the solar energy reflectance of it is around 0.07 (7%, for both front and back … WebMar 8, 2024 · This enables us to calculate the corresponding reflectance of the standard glass sample as 0.100056032172. We then utilize the rendering equation to calculate the reflectance radiance of the standard sample as well as each smoothness material in the virtual reality platform. To simplify the calculation process, we fix the incident radiance at 1.
