BOWLING GREEN STATE UNIVERSITY – CONKLIN RESIDENCE HALL INDOOR AIR QUALITY/HVAC UPGRADES

Conklin Hall had long suffered from a lack of ventilation and humidity control in the common areas and resident rooms. In addition, the aging air-cooled chillers were at the end of their life expectancy. The primary purpose of this project was to address these issues. The project had an extremely tight schedule with approximately three months of design time and four months for construction.

HVAC upgrades included the following:  Installation of an outside air ventilation system for resident rooms and common areas, connection to existing Chiller Plant CCP-1 for chilled water supply, installation of a chilled water heat exchanger to separate the building and campus chilled water systems, and removal of the existing air-cooled chillers.

• Added a structural frame on the roof for the new rooftop air handling unit
• Added vertical shafts and horizontal soffits for duct distribution
• Installed direct buried chilled water pipes between Conklin Hall and CCP-1
• Installed a plate and frame chilled water heat exchanger to isolate Conklin Hall from CCP-1
• Installed new chilled water pumps
• Installed a new 6,500 CFM 100% outdoor air DX cooling/gas heat rooftop unit to supply all 4 floors
• Installed exhaust systems to avoid building over-pressurization
• New ductwork and piping routed above roof due to lack of ceiling space on all floors

HAWA was the lead professional as well as the MEPT engineer. We managed the design team during the design phase and facilitated weekly meetings during the construction phase.
