Protocol for the comprehensive evaluation of building-associated illness.

A protocol is outlined that represents a multidisciplinary approach to investigations of problem buildings and building-associated illness. The protocol includes methods to obtain background information on a problem and to conduct the initial site visit. The initial visit often leads to a more extensive medical investigation and environmental evaluation, as covered in this paper. The protocol also describes how the results of medical and environmental evaluations might best be analyzed to make ways to correct problems.
