Visual Reference Modules

The Visual Reference module contains pictures of IAQ problems and solutions. Learn about the IAQ issues contained in each picture by referring to alt-text contained on the pictures. You may find explanations in text, or in other visual guides which show air movement flows, or pollutant flows as various elements in the building are changed.
