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

1. For architectural design institutes: This data can be used to calculate the light intensity of reflected light entering buildings from surrounding black marble across different wavelength ranges, supporting the design of architectural optical environments.
2. For black marble component manufacturers: They can use this data to calculate the light reflection performance of produced components across different wavelength ranges, guide process adjustments for products, and reduce light environmental pollution.
3. For environmental law enforcement agencies: This data can be used to calculate the transmittance level of reflected light entering the indoor spaces of entities affected by light pollution, where the reflected light is increased due to the installation of black marble on surrounding buildings, thus enabling the evaluation of light pollution impact.

Algorithm Rules:
1. Data Source: The data is derived from the tested and calibrated wavelength-by-wavelength energy distribution of the reflected spectrum of ordinary tempered black marble. The measurement is conducted using a spectrophotometer with a 1 nm wavelength step for most spectral ranges, and a 5 nm wavelength step for the 1700–2500 nm band.
2. The reflected light transmittance $
ho(b)$ of black marble is calculated as:
$$
ho(b) = frac{sum(W(i) cdot
ho(i))}{sum W(i)}$$
Where $W(i)$ represents the radiant energy of sunlight reflected by black marble at a single wavelength, and $W(i) = G(i) cdot F(i)$. $G(i)$ is the radiant energy of the solar spectrum at a single wavelength, $F(i)$ is the reflectance of black marble at each individual wavelength, and $
ho(i)$ is the transmittance of a specific material at a given wavelength. The numerator $sum(W(i) cdot
ho(i))$ denotes the total reflected spectral transmittance energy of black marble within the target calculation or test band, while the denominator $sum W(i)$ represents the total reflected solar energy of black marble within the same target band.
3. By testing the transmittance of arbitrary energy of the material at each wavelength and then conducting calculations using this dataset, the reflected light transmittance of black marble corresponding to the target band for a given material can be obtained.
