AHU LAB DEHUMIDIFICATION

• Following the AHU 4 Lab Dehumidification Study, we proposed a new control strategy to manage lab humidity levels.
• The project included the design and construction of the Phase I and Phase II recommendations from the study report. Phase III was the turnkey design portion of the project.
• Phase I. The Phase I control upgrades included new humidistats, a new hot water reheat coil, and revisions to the BMS program.
• Phase II. Our team designed new supplemental cooling to support dehumidification in the hottest, most humid weeks of the summer. We also designed new doors, a vapor barrier, and drywall in the garage door service chase.
• Phase III. During the lab AHU turnkey design-build phase, we studied the lab humidity trends and operational data to provide system adjustments and AHU replacement options.
• After the equipment design and central plant adjustment, plans were approved for our team to manage and contract all the construction activities.
