Old Jordan Hall is a seven story building opened in 1971. A new addition providing laboratory, office and classroom space was opened in December 1995.

The first floor of Jordan Hall contains two lecture halls, each seating 152 students, as well as smaller seminar room and anatomy laboratories. The majority of the first and second year lectures are given here. The second floor houses additional student laboratories designed for both individual exercises as well as group experiments and teaching sessions in microbiology. The rest of the second floor contains basic science research laboratories.

The purpose of the project was to resolve the following issues: 1) nearly all of the HVAC infrastructure equipment was as old as the building; thus it was well beyond anticipated life expectancy and in dire need of replacement; 2) distribution components (ductwork and piping) were obstructed and/or overloaded; 3) controls were outmoded, limit flexibility ,and include only minimal interface with the central campus system; 4) provisions for energy reclaim, system redundancy, and adaptability to change were minimal to nonexistent; 5) spare capacity existed for heating only, which in fact wasted energy; 6) there was no smoke evacuation or stairway pressurization, which was noncompliant with current code; and 7) the HVAC infrastructure concepts were no longer commensurate with modern research laboratory facilities.
