Static distribution factor of direct solar radiation(直達日射の静的な分配係数) Direct solar fraction of the floor:（床面への直達日射の分配係数） The remaining direct radiation is distributed area-weighted to the walls of a zone.（その他の直達日射は面積按分で壁に分配されます）
I need a 10 minute daily profile. I tried to do that with forcing functions and calculated that my profile requires minimum 146 points. But the maximum limit of the forcing function (Type 14h) in trnsys is 100 points.
The overall development of DAYSIM has been coordinated by Christoph Reinhart since 1998. The global illumination calculation in DAYSIM is based on the RADIANCE backward raytracer. Past and ongoing development work for DAYSIM has been conducted at
