Hello again, i have another question about external shading and the radiation. I know that it can be controlled with an equation using the radiation as input like: Radiation_Input → Equation: =gt(Radiation_Input, X) → Output linked to type 56 Shading But here is my question with the X in the equation. I have a german TRY (.dat) weather file and the radiation in this file is already given in W/m². Do i still need to convert this to kJ/hr m² ? mit freundlichen Grüßen Sascha Heinze |
