Acceptable Levels of Indoor Air Quality – IAQ

A key requirement for a “Healthy” building is having an acceptable level of indoor air quality for the people in that building.  The EPA ranks IAQ as one of its top five environmental concerns.

IAQ Outside air introduced into the buildingAccording to a USEPA study, the levels of contaminants in industrial facilities, commercial office buildings, schools, governmental facilities and other indoor environments can be many times higher than levels found outdoors.

Common problem sources are:

  • Manufacturing processes
  • Interior maintenance activities
  • Renovation projects
  • Office and cleaning chemicals
  • Off-gassing from furnishings and carpets (voc)

From the EPA’s web site :

“In the last several years, a growing body of scientific evidence has indicated that the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities. Other research indicates that people spend approximately 90 percent of their time indoors. Thus, for many people, the risks to health may be greater due to exposure to air pollution indoors than outdoors.”

For the building to be “Sustainable” the correct amount of outside air needs to be introduced into the building thereby maintaining a healthy environment.  Outside air displaces air in the building at a rate that has been determined is necessary to maintain an acceptable level of indoor air quality.  Obviously the cost to heat and cool the outside air that is introduced into the building over the life of the building can add to the energy cost, especially when too much outside air is introduced.  On the other hand when not enough outside air is introduced the possibility of sick building syndrome (SBS) or “building related illness” (BRI) is increased.

How do you know you are getting the correct ventilation to building occupants?
