So if Radiation_Input (the output from your weather data reader probably - Type99?) is in W/m2 then X also needs to be in W/m2. It is more likely that Radiation_Input is in kJ/h.m2 though, in which case X also needs to be in kJ/h.m2.<br>Best,<br> David<br><br><br>On 6/15/2012 05:04, Heinze wrote: <o:p></o:p></p><p class=MsoNormal>Hello again,<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>i have another question about external shading and the radiation. <o:p></o:p></p><p class=MsoNormal>I know that it can be controlled with an equation using the radiation as input like: Radiation_Input ˇć Equation: =gt(Radiation_Input, <b>X</b>) ˇć Output linked to type 56 Shading <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>But with the X in the equation i am not sure.
