I've got a 2 story mall concourse with very large openings (short story: on the second floor you can only walk at the perimeter, but otherwise see here) and that is conditioned by the same HVAC system. I've ended up defining it as a single space and thermal zone.

Basically I want to end up calculating correctly everything that needs to be calculated, including people, plug loads, and design specification outdoor air. I have my occupancy defined at people/ft², my plug loads as W/ft² etc.

I'd like to override the space area so that I end up with something like 1.6 times what it should be, and I'm wondering if there's a way to do this in OpenStudio or I'm left having to calculate my plug loads, outside air CFM, etc as a side calc?

(Knowing that this will also require some proper explaining for the reviewing authority as to why the output reports mentions LPDs that are out of range etc...)
