mechanical blinds outside the building

Hi there, For interior lighting, the guide reference indicates that the direct beam illumination intersects solid or opaque surfaces and does not spill to the outside. My question is, the building of the project which I’m working counts with mechanical blinds, and they can be close at night a provide for sure a solid surface, is this possible to document compliance for this credit?. in the other hand all lights inside the building are partially shielded in order that light is conducted to the task desk but not to the sides. Is this compliant with the credit? Or what is the best way to document interior light if I do not count whit automatic controllers? Thanks in advance.
