We usually think in terms of a progression from design to installation to occupancy. However, eradicating IAQ problems often requires working "backwards" from specific occupant symptoms to the likely source. By W. Edward Montz, Jr., Ph.D., and Theodore J. Passon, Jr., Ph.D.
From patient conditions to the placement of diffusers and beds, many variables are involved in creating
