Polyurethane foam is widely utilized in construction engineering. The wavelength-resolved reflected spectral energy distribution data of polyurethane foam serves as a standard reference computational dataset for calculating the reflected spectral transmittance of polyurethane foam materials, and can be applied to compute the reflected light transmittance of polyurethane foam materials across any wavelength band (280 to 2500 nm range).

1. For architectural design firms, this dataset can be used to calculate the light intensity of different wavelength ranges of reflected light entering buildings via surrounding polyurethane foam, facilitating architectural optical environment design.
2. For polyurethane foam component manufacturers, this data can be utilized to calculate the light reflection performance of produced components across various wavelength ranges, guiding product process adjustments to reduce light pollution.
3. For environmental law enforcement agencies, this dataset can be used to calculate the transmittance level of reflected light entering indoor spaces or areas affected by light pollution, where the amount of reflective materials is increased due to installed polyurethane foam on surrounding buildings, thereby assessing the impact degree of light pollution.

Algorithm Rules:
1. Data Source: The data is derived from tested and calibrated wavelength-resolved reflected spectral energy distribution of polyurethane foam, measured by a spectrophotometer with a 1 nm wavelength step.
2. The reflected light transmittance of polyurethane foam material ρ(b) = [∑(W(i)·ρ(i))] / [∑W(i)]. Where W(i) is the radiant energy of sunlight reflected by polyurethane foam at a single wavelength; W(i) = G(i)·F(i), in which G(i) is the solar spectral radiant energy at a single wavelength, F(i) is the wavelength-by-wavelength reflectance of polyurethane foam, and ρ(i) is the transmittance of a certain material at a specific wavelength. ∑(W(i)·ρ(i)) refers to the total reflected spectral transmittance energy of polyurethane foam within the target calculation or measurement wavelength band, while ∑W(i) refers to the total reflected solar energy of polyurethane foam within the target calculation or measurement wavelength band.
3. By measuring the transmittance of arbitrary energy of the target material at each individual wavelength and then conducting calculations using this dataset, the reflected light transmittance of polyurethane foam for that material within the corresponding wavelength band can be obtained.
