The window material:blind was taken by the Energy Plus Library and then i created an object in WindowProperty:ShadingControl. Taking into consideration that i have done everything according to the input/output reference where it is mentioned that Window property:shading control is referenced by windows and glass doors, I can not think of anything wrong. I could use your valuable advices. Thank you very much.
