Smoking Prohibition in a Border Crossing Building

We are assessing the possibility of pursuing LEED Certification for a Complex of four buildings at the Border Crossing between Chile and Argentina. One of these buildings is residential and will house the Customs officers and employees bedrooms and resting areas. In this particular building, the architect is considering an smoking designated room (which complies with the exhaust and isolation requirements) but we think this building must comply with requirements for Residential Projects which means non-smoking indoor and blower door test. Are we right? or is enough to comply by providing the designated smoking area?. Thanks in advance.
