We are currently working on NC V4 Group buildings. Project is G+2 with total of 100 buildings and distance between the buildings are less than 25 feet.

For an extension of an excisting airport that is possible LEED certified, the client desires interior smoking areas to prevent 'illegal' smoking inside the airport.

We are currently working on an Airport Project and would like to pursue LEED certification.

We have a project where the hallways are pressurized to provide ventilation air thru door undercuts.

I am really confused with the language of this credit , can you please clarify the below 1- Does EACH unit have to be sealed and Compartmentalized or only Residential units allowing smoking?

We have some overhead rolling doors (for trucks to enter the garage portion of the commercial building) along with some man doors.

Dear Sir or Madam, Smoking must be prohibited within 25 feet of building entries, outdoor air intakes, and operable windows.

I just need clarification on something. In the reference guide, it states "Residential only" for Option 1.

Does the ETSC prerequisite apply during construction as well?
