Second, stick these phrases in Google:
infiltration guidelines hvac design
infiltration guidelines energy modeling

You'll find about 100 good references from ASHRAE, PNNL, NIST, MIT, NIBS, and others.

Technical paper is the result of experience and studies.
for the economy side, if the infiltration load will cause a damage to business, then it is better to close this business and look for something else.

This may not really be accurate, but has some science to it. When I have time I research more on what DRWeig suggested. but the method i described should work for the load. it won't really work with energy simulation since that flow will be highest at the coldest day.

An air curtain can mitigate a lot of what will sneak in. A vestibule or revolving door even better.
In my area, the folks in the small markets just have to dress warmly and wear double socks in the winter.
