The term indoor environmental quality (IEQ) and indoor air quality (IEQ) are often confused.  The basic difference between the two is that IEQ refers to the environment that exists inside a building such as the concentration of CO2 gases, the thermal conditions, moisture and dampness (Kumar 2002).  Whereas IAQ is strictly, “a function of the interaction of contaminant sources and the effectiveness of ventilation utilized to dilute and remove air contaminants”(Bearg 2008). 

Major interior design decisions that impact indoor air quality may include:

·          Using a solid surface flooring instead of carpet

o    Carpets can capture and retain dust, dander and other particulate air contaminants

·         Antimicrobial coatings for surface disinfection

o    Can reduce contaminates in the air

·         Dehumidifiers

o    Control mold-growth and airborne allergens
