Hello, I am trying to integrative control of passive systems (i.e., window ventilation, shading device and daylighting).

I modelled the building using designbuilder. I chose the option to crack template and blind:shade I have some questions and problems.

My shading device in DSB is "Shade-roll" - Outside after conversing to IDF, I found something strange.

First, WindowMaterial:Shade object is generated. Second, But in the WindowShadingControl, <field:construction with="" shading="" name=""> cannot be changed to autogenerated WindowMaterial:Shade object.. Does this means that I should enter the name of construction object(window) and shading material individually? I wonder the reason..

Third, is "Shade-roll" in DSB component a screen shading device (Up&down manipulation by roller)?

Fourth, about the E+ model with airflow network and shading control, shading and natural ventilation effect can be simultaneously and independently manifested?

(For example to understand) if I open the window and roll shade screen down, Will be the irradiation beam blocked and airflow supplied to an internal zone "Independently without any interactive effects"?

Thanks for your answers
