Wes, indoor air quality was one of the first issues they discovered when they started 'sealing up' the buildings. Now there are rules/laws that stipulate a certain amount of fresh air be introduced/exchanged and that for sure adds to the energy cost. A continuing problem is building maintanence workers closing up the fresh air intakes to save energy, then people get sick, the vents are opened back up and the workers are like, "Wasn't us, we didn't do nothing, see there open."
