While architecture offices are increasingly using CADD systems for drafting purposes, architectural schools are pursuing projects that use the CAD data base for new applications in the analysis and evaluation of buildings. This paper summarizes two studies done at the University of Michigan, Architecture Research laboratory, where the CAD system was used to develop a fire safety code evaluation program, and an emergency egress behaviour simulation.  The former one takes the National Fire Protection Association (NFPA) Life safety Code 101 as a basis, and generates the code compliance requirements of a given project. The ether study accepts people as information processing beings and simulates their way finding behaviour under emergency conditions. Both of these studies utilize the graphic characteristics of the CAD system, producing color displays on the CRT screen, and also outputting information in tabular form which refers to the display on the screen. Both of them also have plotting options.
