How does Resstock determine building aspect ratio?

I understand many properties come from the conditional probability files here: https://github.com/NREL/resstock/tree....

Is there a similar file or an assumption somewhere for determining a building's aspect ratio? Asked another way, how do you go from an input of total sqft to actual wall dimensions?

ResStock currently assumes a dwelling unit aspect ratio of 1.8 (or 1/1.8=0.56 for some building types) as defined here in the options_lookup.tsv.

Unit aspect ratio is defined as "The ratio of front/back wall length to left/right wall length for the unit, excluding any protruding garage wall area." (You can find that definition by searching for "aspect ratio" in this README).
