How do I correct North axis angle in OS?

edit

1._How can I define the North Axis angle in my model if the geo-location is not available for my SU version (SU Pro 2016).

After I finished the geometry, I realized the EAST facade is oriented wrong. I read in some of the answered questions here that the green axis represents north in my model, which was supposed to be correct, but when I use the Shadow tab and start swiping from morning to afternoon in SU I realize the sun is rising in the wrong facade. 2._If I rotate the building does that interfere in the simulation? I mean, will OS understand the correction in the orientation I've done?

3._In Legacy/Euclid there is a place to configure the north axis angle, but in OS no. So, how can I make sure it is correct in OS?

Thanks
