Cooling Design tab on Model Options dialog and General tab on Cooling Design Calculation Options dialog.
Solar Options allow you to control aspects of the model related to solar gains.
The standard wall, floor, roof surfaces defining the current building provide shading but by default the other buildings on the site are excluded from the analysis. Use this option to include other buildings on the site as shading obstructions.
Note: there is no way to simulate more than 1 building at a time. All external surfaces in buildings other than the current one are modelled as shading surfaces. If you need to model the adjacency of another building in contact with the current one, you can use the adiabatic adjacency option to model the touching surfaces.
Note: if one or more 'other buildings' are large/complex then you could generate a large number of shading elements and the simulation could be slow (even if the current building being simulated is simple).
When zones are excluded from simulations, by unchecking the Include Zone checkbox, it is often still necessary for the excluded the zone's surfaces to be used to shade other parts of the building. Checking this checkbox ensures that all building surfaces are used in shading calculations, even those that have been excluded.
