Andrew J. Desiderio, P.E., P.C. was retained by the Facilities Department of Columbia University for two projects involving St. Paul’s Chapel.  The first project included the design of a ventilation system for the basement toilets, kitchen and art gallery.  This chapel was constructed in 1904 and does not allow sufficient space for the necessary ductwork and fans.  In addition, it was necessary to install an exterior exhaust louver while not affecting the facade of the building.

The University then requested a ventilation system for the meeting room located on the west end of the basement.  Effective ventilation includes the imposition of outside air into a space, thus a heating and cooling system was necessary to maintain comfortable space conditions.  This was accomplished via use of the University tunnel system as a means of exhausting the area and the design of a compact heating and cooling system within the confines of the area housing the compressor for the pipe organ.

Andrew J. Desiderio, P.E., P.C. designed a new chemistry laboratory in room 412 of the Havemeyer Building to be used by Professor V. Cornish, PhD.  The new organic chemistry laboratory was housed in a former storage closet and included three new exhaust hoods, work benches and an integral student desktop work area with telephone and computer networking connections.

Andrew J. Desiderio, P.E., P.C. was retained by Columbia University to design new laboratories, classrooms and a computer laboratory for the Chemical Engineering Department. Previously, we had performed a study of the laboratory fume hood exhaust system to determine the feasibility of adding new laboratory hoods to the system.  We also assisted Columbia University in evaluating a new, low airflow hood developed by LabCrafters for use in this laboratory, as the existing exhaust system did not have the capacity to add conventional hoods to the system.   This design effort also included the conversion of a storage room into a computer center for the chemical engineering students, other laboratories and instructional space.
