Helmut Jahn was born in Nuremberg, Germany in the midst of war in 1940. His first official architectural schooling occurred at the Technische Hochschule (Technical University) of Munich from 1960 to 1965. Here Jahn’s education was primarily focused on the means and methods of architectural construction, of which influence is shown in the technical mastery of many of Jahn’s buildings. After graduation he emigrated to the United States to attend graduate school at Illinois Institute of Technology, but never finished his master’s degree due to the fact that IIT only allowed dissertation from students who completed undergraduate and graduate courses at the institute. Jahn was instantly struck by the Seagram building upon his arrival to the US, which laid the foundation of a lifetime of architectural creation influenced by Mies van der Rohe. He went to Chicago to enroll in IIT, and applied for position at Mies’s office along the way, which proved unsuccessful. At IIT, Jahn studied under Myron Goldsmith, Fazlur Kahn, and David Sharpe, who are all well-known for their studies of structures in tall buildings, and was imbued with a fascination of tall structures. Following his education at IIT, Jahn got a job at C.F. Murphy with Gene Summers, a former Mies assistant, Jahn’s influences clearly originate in modernism, he which began his practicing career. He quickly would become embraced modernism’s architectural ideas: the expression the Executive Vice President and Director of Planning and Design of volume rather than mass, the expression of structure, at the firm, and eventually take sole control the firm now named visual weightlessness, and the celebration of light as Murphy/Jahn. In 2012, Jahn renamed the firm to JAHN, and building material; however, his works break from the pure announced the firm’s eventual successor, Francisco Gonzalez Modernist oppressive expression of rectilinear form (James R Pulido. Thompson Center 1985). More mature than the postmodern application of ornament (which he surely used on the Park Helmut Jahn’s work often defies categorization. While many of his Avenue Tower), Jahn’s later work utilizes structure as as an works fit squarely into the Post-modern style (One Liberty Place, inseparable ornament through which formal expression is Philadelphia; Messeturm, Frankfurt), others bridge International realized (Sony Center, Berlin, 2000; Cologne Bonne Airport, and Post-modern, combining the aesthetics of structural Cologne, 2004); though, his latest works gravitate towards expression and reactive forms to create a hybridized architecture an engineered aesthetic.

Moore described collection would remain on campus, and the underground Nuclear Energy as being “like an architectural cathedral”, chamber would be well insulated by the earth, allowing The Mansueto Library is an excellent example of a well- integrated building. All of the building’s major systems seamlessly blend with the architectural elements, resulting in clean lines and architectural expression free of clutter and distraction. The totally transparent 1-story dome eliminates the ceiling space offered by typical buildings as a space to house ductwork, pipes, conduit, and other necessary building technologies. With no hidden space to contain these systems, Jahn and the other building disciplines saught ways to integrate them into the architecture in efficient and intelligent ways. The nature of the facade system provides a gap between the steel tube structure and the glass: an opportune space to run fire suppression piping and electrical conduit that would be out of sight of the building occupants.
Air distribution and condensation control play an important role all buildings, especially in buildings that are clad entirely in glass. Again, with no ceiling space to conceal the HVAC systems, the design team utilized the ample space under the main floor to distribute the air. The most critical conditioned space is the underground book storage area and the main HVAC equipment was logically located adjacent to it, underground. The ductwork which serves the main floor spaces simply extends from the air handling units and gets routed under the floor to the diffusers above. The air enters the reading room in two ways, one, through nozzle-type diffusers located in a ring around the exterior of the building which throw the air at high velocity washing the interior face of the glass facade, and two, up through the metal columns located throughout the floor space in the reading room. In the cooling season, the air in these columns is leaked out at slow velocity, allowing it to settle down at the floor level. The cool air will remain at the occupiable floor of the reading room and warmer air will rise created stratified zones of air. Through the integration of the HVAC system with the architecture and structure of the library, the spaces are conditioned properly and efficiently without detracting from the architectural concept and integrity. 72°F 30-60%RH
