Zone Context not affecting the simulation

I am trying to make a simulation to understand the light in the interior of a commercial building (glazing facade), when I applied HBcontext it does not seems to affect the result of the simulation, when I change the material of the context to glass it seems to work, trying to understand whats going on. The surrounding buildings are glazing facades the same as the floor that I am simulating (want some help with a better material config of this as well). Any other advice to improve the simulation would be nice too. Thanks !! (634.9 KB)
