We have tectum panels (acoustic/insulation panels) above our beams. Do we have to add additional panels to the wall to make up for the ceiling area occupied by the exposed ceiling structure/beams?

It depends on what approach you want to take in the templates.
If you're going for the "all ceiling area = NRC 0.7 or better approach", then you would need to add panels. If you are willing to make RT calculations instead, you can make the calculation and you may, or may not, need to add more panels depending on the results.
If the space is greater than 20,000 cu. ft., however, the RT caluclation is your only option.
