Granite is extensively applied in construction engineering. The wavelength-resolved reflected spectral energy data of granite serves as the benchmark reference data for calculating the surface reflected spectral transmittance of granite materials, and can be utilized to compute the reflected light transmittance of granite materials across any wavelength band within the range of 280–2500 nm.

1. For architectural design institutions: This data can be used to calculate the light intensity of various wavelength ranges of reflected light entering buildings through surrounding granite structures, facilitating optical environment design for buildings.
2. For granite component manufacturers: This data enables the calculation of the light reflection level of produced components across different wavelength ranges, guiding product process optimization to mitigate light pollution.
3. For environmental law enforcement agencies: This data can be used to calculate the level of reflected light entering indoor spaces (enclosed areas) of subjects affected by light pollution, specifically the increased reflected light caused by granite installations on surrounding buildings, and to assess the degree of light pollution impact.

Algorithm Rules:
1. Data Source: The data is derived from tested and calibrated wavelength-resolved reflected spectral energy distribution of granite, measured using a spectrophotometer with a 1 nm wavelength step for the 280–1700 nm range and a 5 nm wavelength step for the 1700–2500 nm range.
2. Calculation formula for granite reflected light transmittance: $
ho(b) = frac{sum W(i) cdot
ho(i)}{sum W(i)}$, where $W(i)$ is the radiant energy of sunlight reflected by granite at a single wavelength, and $W(i) = G(i) cdot F(i)$. $G(i)$ represents the solar spectral radiant energy at a single wavelength, $F(i)$ is the granite reflectance at each individual wavelength, and $
ho(i)$ is the transmittance of the material at a certain wavelength. $sum [W(i) cdot
ho(i)]$ refers to the total reflected spectral transmittance energy of granite over the target calculation/test band, while $sum W(i)$ refers to the total reflected solar energy of granite over the target calculation/test band.
3. By testing the transmittance of arbitrary energy of the material at each individual wavelength and then performing calculations using this data, the reflected light transmittance of granite corresponding to the target wavelength band can be obtained.
