[TRNSYS-users] How to specify no movable shadings when importing 3D building using the wizard

[Marion Hiller]

Yossef,

some further clarification on the internal control of shading:
The shading control is applied only if a window has defined a shading factor >0 with internal control.

If you didn’t specify this in your 3D building project for a window surface, the window surface is unshaded no matter what is values are specified by the internal shading control

Thus, it is recommended to
 - not use strange values for the shading control for switching of shading
- but set the shading factor for window surfaces to 0 for unshaded.

Yossef,

 I usually set those values to close if > 10000 and open if less than 10000. The value in question is the incident solar radiation (in kJ/h.m2). Typically the solar radiation will never exceed 5000 kJ/h.m2 so the value of 10000 removes the shades from consideration.

 Your method sounds to me as though it will work as well. I am not sure on the source of 120 and 140 but setting the max shade value to 0 will do the job.

kind regards,

 David

Dear Trnsys community,
I'm using the wizard to import the 3D building project, but it shows me options for shadings, I want to specify that there is no shadings, so I left "close if total..." set to 140, "open if total..." set to 120, and for maximum I put 0 as a value. Is that the correct way to ignore movable shadings?
Thank you
