The wavelength-distributed reflective spectral energy data of architectural glass serves as the benchmark computational data for calculating the reflective spectral transmittance of architectural glass surfaces, and can be used to compute the reflective light transmittance of architectural glass materials within any wavelength band ranging from 280 to 2500 nm.

1. For architectural design institutes: This data can be utilized to calculate the light intensity of different wavelength ranges of light entering a building via the reflected light from opposite architectural glass, thereby facilitating the optical environment design of the building.
2. For architectural glass manufacturers: They can use this data to calculate the light reflection performance of their produced glass across different wavelength ranges, obtain glass reflection and transmittance data, and guide the adjustment of product production processes.
3. For environmental law enforcement agencies: This data can be employed to calculate the transmittance level of reflected light from reflective materials of architectural glass on opposite or side buildings entering the indoor (space) of the subject affected by light pollution, so as to evaluate the impact degree of light pollution.

Algorithm Rules:
1. Data Source: The data is derived from the tested and calibrated per-wavelength energy distribution of reflected spectra of ordinary tempered architectural glass, which is measured by a spectrophotometer with a 1 nm wavelength step in the 280–1700 nm range and a 5 nm wavelength step in the 1700–2500 nm range.
2. The reflective light transmittance ρ(b) of architectural glass is calculated as: $$
ho(b) = frac{sum W(i) cdot
ho(i)}{sum W(i)}$$ Where $W(i)$ is the radiant energy of sunlight reflected by architectural glass at a single wavelength, and $W(i) = G(i) cdot F(i)$. $G(i)$ represents the radiant energy of the solar spectrum at a single wavelength, $F(i)$ is the reflectivity of architectural glass at each wavelength, and $
ho(i)$ is the transmittance of a specific material at a given wavelength. $sum [W(i) cdot
ho(i)]$ is the total reflective spectral transmittance energy of architectural glass within the target calculation or test band, while $sum W(i)$ is the total reflected solar energy of architectural glass within the target calculation or test band.
3. By testing the transmittance of arbitrary energy of a material at each wavelength and then performing calculations using this data, the reflective light transmittance of the architectural glass corresponding to the target band of the material can be obtained.
