Requirements Capture in Arcadia Method.

Apologies if this is posted in the incorrect section. I tried posting in the “arcadia modelling method” specific section and was not able to.
I’m new to systems modelling and am trying to understand how implementation requirements fit into the arcadia method. For example, if you want to specify designing to a specific cost which may in turn limit your materials selection. Or adding a regulatory requirement for CO2 emissions.
Neither of these would seem to fit into operational capability. Is Arcadia just not intended to capture requirements like this?
Thanks
