Annual Daylight Confusion

I am analyzing DA in a simple open office. For testing the results I create a wall between my room but still the DA of points behind the wall are not zero. Does it have a bug?

With this visualization I can’t really tell where is the window and where is the wall. You can check hourly data and see if it makes sense. You can also use import rad component to import the radiance file and see if the model is exported correctly.

Only the south wall is glass. I understood where is the problem. I used conceptual dynamic shading. When I disconnect it it will be correct.Does dynamic shading apply for all walls?Or just windows?
