Solutions After Conducting an Indoor Air Quality Investigation (Part 3)

Heating and air conditioning systems are sometimes complex and can require evaluation by outside contractors or specialists.  To eliminate many of the probable indoor air quality problems, however, there are three areas that can be easily addressed to some degree by building owners.  These are a) filtration of airborne particulate, b) removal of built-up contamination, and c) the control of microbial growth.

How to Conduct an Indoor Air Quality Investigation? (Part 2)

A preliminary indoor air quality investigation, performed by a building owner, can begin to find solutions for problems caused by airborne particulate and microbial growth.

One primary outcome desired from any IAQ investigation should be to see and document what is normally not seen, namely the existing condition of the entire HVAC system. Our downloadable diagram outlines problem-solving logic that should be used to conduct an investigation. 

Causes for an Indoor Air Quality Investigation (Part 1)

Building owners or their representatives, who are responsible for maintaining the building’s indoor air quality (IAQ) systems, are becoming more aware of their responsibility and liability for the IAQ in their buildings.  A major reason is the old true adage “out of sight, out of mind”.  Most indoor air quality problems are not visible to building owners and occupants.  As a result, many IAQ problems have been ignored.
