The output variabel ZonneweringSchema gives the correct values per hour: between 0.0 and 1.0 So i guess the function works well. Only the shades itselfs dont use the EMS program, rather de schedule only: Schedule:Constant, ZonneweringSchema, Fraction, 1.0; So the shades are transparant always, they dont influence the inside temperature, and they should! Thats also what the error message said: ** Warning ** Shading:Zone:Detailed="ZN001:WALL-EAST:SHADE001", Transmittance Schedule Name="ZONNEWERINGSCHEMA", is always transparent. ** Warning ** Shading:Zone:Detailed="ZN001:WALL-SOUTH:SHADE001", Transmittance Schedule Name="ZONNEWERINGSCHEMA", is always transparent. ** Warning ** Shading:Zone:Detailed="ZN001:WALL-WEST:SHADE001", Transmittance Schedule Name="ZONNEWERINGSCHEMA", is always transparent.
What am I doing wrong? I cant find the problem.
