Experiments are used to test how air and pollutant move indoor under differing conditions. One way to perform
tests under controlled conditions is to conduct them in experimental chambers. Typically environmental conditions,
such as temperature, relative humidity, and air infiltration, can be more tightly controlled in experimental
chambers than in real buildings. This increased control allows researchers to investigate the effect of changing
conditions on contaminant airflow. The construction of experimental chambers varies considerably based on the
purpose of the research. For instance, stainless steel chambers are used to investigate emissions from building
materials, while chambers which are built and furnished like a typical room are used to investigate aerosol transport
within homes.
