Indoor environmental contaminants can originate within a home or building, or be drawn in from outdoors. If contaminant concentrations are excessive, Indoor Environment Quality (IEQ) problems can arise, even if the HVAC system is properly designed and well maintained. Foster's investigators have found IEQ problems caused by ventilation system deficiencies, overcrowding, tobacco smoke, microbiological contamination, and outside air pollutants. Maintaining a healthy and comfortable indoor environment requires integrating many components of a complex system. Indoor environment problems are preventable and solvable. |
