    I would think the difference in air conditioning, especially big commercial buildings, would more than make up the balance.

      Overall… I agree with your take.

      I counter with electricity costs of keeping them AC units at the clean room mouth running 24/7 vs in presence of new contaminant and how dust blows both ways and mold tends to blow one way.
