2 Air Conditioned Football Stadium and Convention Center Chilled Water Pipe Insulation Assemblies Failure and Remediation with New Developed Insulation Systems

Willis J. “Bill” Brayman, Brayman Insulation Consultants

At a football stadium & convention center, in Houston, Texas, the original chilled water (CHW) pipe insulation systems required replacement due to extensive moisture intrusions. Although the CHW flowed continuously, the Air Handling Units were shut down when the building was not in use. This allowed the indoor environments to be exposed to Houston’s outdoor high temperatures and humidity during those times. Remediation required replacing the CHW pipe insulation with an insulation system of a totally different design without major pipe relocations and while the CHW circulated through the pipes being reinsulated.
