For example, interior spaces are often subjected to a specific amount of illumination from the sky component (SC) due to an inherent pre-existing sky angle which makes it necessary to capitalize on other components of daylight. The research contains numerical calculations and charts that depict the behavior of ERC under different parameters UR - http://172.23.153.220/th.pdf ER -
