Project Description

Oculus Inc. led a multidisciplinary team to execute a comprehensive GSA Stack Effect Study at the Thomas F. Eagleton Federal Courthouse in St. Louis, MO. This investigation focused on assessing air infiltration caused by stack effect and quantifying pressure differences across the building envelope. Oculus’ services included multiple on-site investigations, targeted testing, and both drone-assisted and direct visual inspections to evaluate exterior envelope conditions. The team employed THERM modeling and conducted detailed reviews of building materials through original submittals, drawings, and specifications. Based on the findings, Oculus developed and presented eight distinct, scalable solutions to mitigate the stack effect, each tailored to improve envelope performance, reduce energy loss, and enhance interior comfort.
