挤塑苯板在建筑工程中大量应用，挤塑苯板反射光谱能量按波长分布数据是计算材料挤塑苯板表面反射光谱透射率的基准计算数据，可以用于任意波段（280-2500nm范围内）的材料挤塑苯板反射光透射率的计算。1、对建筑设计单位来说，利用本数据可以对建筑物通过周围挤塑苯板构建反射光进入建筑不同波长范围的光强进行计算，进行建筑光学环境设计。2、对挤塑苯板构件生产商来讲，可以通过本数据计算生产部件在不同波长范围的光反射水平，指导产品调整工艺，降低光环境污染。3、对与环境执法机构来讲，可以通过本数据计算受到光环境污染主体室内（空间）由于周边建筑物安装挤塑苯板后反光材料增加的室内（空间）反射光的透射进入水平，评估光污染影响程度。算法规则：1、数据来源：数据来源于经测试和校对的挤塑苯板反射光谱逐波长能量分布（用分光光度计按1nm波长步进测试）。2、材料的挤塑苯板反射光透过率ρ（b）=∑W（i）*ρ（i））/∑（W(i)，W(i)是太阳光经挤塑苯板反射的光线在单个波长的辐射能量，W(i)=G(i)*F(i)，G(i)是太阳光谱在单个波长的辐射能量，F(i)是挤塑苯板逐个波长的反射率ρ（i）为在某个波长的某材料的透过率，∑（W(i)*ρ（i））为要计算或测试波段的挤塑苯板反射光谱透过能量总和，∑（W(i)为要计算或测试波段的挤塑苯板反射太阳光反射能量总和。3、通过逐个波长测试材料的任意能量的透过率后利用本数据进行计算可以得到某材料对应波段的挤塑苯板反射光透射率。

Extruded polystyrene foam (XPS) is widely used in construction engineering. The wavelength-distributed spectral energy reflection data of XPS serves as the benchmark computational data for calculating the spectral transmittance of reflected light from XPS surfaces, and can be applied to calculate the reflected light transmittance of XPS materials in 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 different wavelength ranges of reflected light entering buildings via surrounding structures installed with XPS, so as to conduct optical environment design for buildings.
2. For XPS component manufacturers: They can use this data to calculate the light reflection level of produced components across different wavelength ranges, guiding product process adjustments to reduce light environmental pollution.
3. For environmental law enforcement agencies: This data can be used to calculate the transmittance level of reflected light entering indoor spaces (or enclosed areas) of light pollution-affected subjects due to the increased reflective materials from surrounding buildings installed with XPS, so as to evaluate the impact degree of light pollution.

Algorithm Rules:
1. Data Source: The data is derived from tested and calibrated wavelength-by-wavelength spectral energy distribution of XPS reflection spectra, which is tested by a spectrophotometer with a 1 nm wavelength step.
2. Calculation Formula for XPS Reflected Light Transmittance ρ(b):
ρ(b) = [∑(W(i) × ρ(i))] / [∑W(i)]
Where W(i) is the radiant energy of sunlight reflected by XPS at a single wavelength, and W(i) = G(i) × F(i). G(i) is the solar spectral radiant energy at a single wavelength, F(i) is the wavelength-by-wavelength reflectance of XPS, and ρ(i) is the transmittance of a certain material at a specific wavelength. ∑(W(i) × ρ(i)) represents the total reflected spectral transmittance energy of XPS within the target calculation or test band, while ∑W(i) represents the total reflected solar energy of XPS within the target calculation or test band.
3. By testing the transmittance of arbitrary energy of the material at each wavelength and using this data for calculation, the reflected light transmittance of XPS corresponding to the target band can be obtained.
