| Research Abstract |
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.
