Indoor Air Quality

Indoor environments are very complex. There is potential for building occupants to be exposed to particulates, vapors, gases, biological agents and objectionable odors from a range of sources from within and outside of the building. Factors such as indoor temperatures, relative humidity, and ventilation levels may also affect how individuals respond to an indoor environment.

Understanding the sources of indoor environmental contaminants and controlling them can often help prevent or resolve building-related worker symptoms or concerns. We provide practical guidance for improving and maintaining the indoor environment. We can:

• Investigate occupant concerns about building conditions.
  
• Identify chemical and biological agents creating problems and locate their sources.
  
• Determine the pathways and driving forces causing pollutants to move within buildings.
  
• Evaluate ventilation system operation and effectiveness.
  
• Test air pressure differentials under conditions of use.
  
• Investigate cases of building related illness and sick building syndrome.
  
• Establish problem prevention and corrective action plans.
