How do we define the shading impact of adjacent buildings on the building of interest in EnergyPlus/OpenStudio?

Let's assume the buildings are in same model, how can we define the shading impact of one tall building on the other building, to understand its impact on the cooling/thermal load of other building?

Is this question contingent to your previous one?

Hi Denis,

Yes, it is linked with the same model we are developing.

If you choose to simulate detached pavilions (as a single facility/building, as discussed here), then make sure to select FullExteriorWithReflections. You should nonetheless do a few sanity check runs to ensure mutual self-shading & reflections (i.e. between pavilions) are simulated as expected.

If instead simulating each building independently (10 buildings == 10 IDFs), then the other buildings would need to be modelled as shading objects (see here and/or here), and yes also select FullExteriorWithReflections.
