Cohn Research Building Laboratory Build-Out

Cohn Research Building Laboratory Build-Out - Chicago, IL


The Cohn Research Building is a 180,000-square-foot, nine-story facility. The $2.2 million project included the build-out of three and one-half floors of general chemistry reserach laboratories, upgrades to existing vivarium ventilation, and various infrastructure system upgrades and enhancements.


The build-out included:

  • A variable air volume lab ventilation system using Phoenix air valves
  • Chemical fume hoods and bio-safety cabinets connected to a large central manifolded exhaust system
  • Radioisotope hoods with separate exhaust fans and HEPA filtration
  • Central piped lab services, including compressed air and vacuum

Infrastructure upgrades included:

  • Modifications to convert office area from 100% outside air to recirculation in order to reduce demand on the existing exhaust system and chiller plant, and to reduce cooling and heating costs
  • The addition of a new 600-ton centrifugal chiller with variable speed drive and associated cooling tower
  • The addition of a new central reverse osmosis (RO) laboratory water system
  • Modification to animal cage washing suite ventilation to maintain required pressurization
  • Enhancement to humidification control for animal holding rooms
  • Complete air balancing of vivarium floors
