"Invisible" exhaust stacks give pharmaceutical maker a cure for uncommon code
The new research facility of Syrrx Pharmaceuticals, Inc. is somewhat unusual, in that its roof exhaust system's stack is not very visible at all. This 84,000-sq-ft high-tech facility, designed for advanced pharmaceutical research applications, contains several hundred individual laboratory workstations with dedicated exhaust fume hoods, which occupy about 80% of building space. The balance is devoted to common area and administrative offices.
Because of the nature of the research conducted there, the building requires 100% conditioned makeup air. The question is, how do you exhaust hundreds of laboratory workstations to eliminate exhaust re-entrainment, air pollution, neighborhood odors, and noise, yet conform to an extremely tough building code that restricts overall height to only 30 ft?
