Formulation of practical solar heat and daylight simulation model considering spectral characteristics of solar and building envelope

根据长期测量的水平光谱太阳辐照度，给出了太阳高度、晴朗指数、云比、可见光色温和近红外太阳辐射率之间的相关关系。另一方面，用正态分布模型近似计算了典型商用玻璃的光谱透过率。同时，对办公空间进行了实验研究，明确了日照色温的空间分布和时间波动对居住者的影响。因此，本研究项目在没有详细光谱数据的情况下，提出了一种考虑可见光和近红外太阳辐射光谱特性的独创性方法。

Based on the long-term measured horizontal spectral solar irradiance, correlation between solar altitudes, clearness index, cloud ratio and color temperature of visible sunlight and ratio of near-infrared solar radiation were shown. On the other hand, spectral transmissivity of typical commercially available glasses are approximated by using normal distribution model. At the same time, we conducted experimental investigation at office space and influence on the occupants by special distribution and time fluctuation of color temperature of sunlight was clarified. As the result, this research project showed an original method to consider spectral characteristics of visible and near infrared solar radiation without detailed spectral data.
