All Things Moisture
Buildings in warm, humid climates are prone to mold and moisture issues that can cause catastrophic failure. Liberty Building Forensics Group (LBFG) provides insight into how to avoid water intrusion, air leakage, condensation, deterioration, and air infiltration problems in new or old construction by achieving tight air barriers and building envelopes. They also discuss using HVAC systems properly to correct building pressurization and achieve dehumidification and humidity control, as well as avoiding mold and moisture problems in green design. A recognized leader in solving, remediating, and litigating complex moisture and mold-related building failures, LBFG has extensive expertise in investigating and resolving construction and design deficiencies.

Contrary to popular belief, mold can occur in painted walls. This wall had a highly breathable textured finish system, and yet mold returned in the guest room walls. This was the condition after the first remediation, when the problem returned.

Building envelope & HVAC interaction in warm, humid zones
View of PTAC unit removed from wall sleeve-room side is to right. Inset in upper left shows front view of unit in sleeve with cover removed. Supply fan draws unconditioned outdoor air (red arrows) into supply fan plenum. Fan also draws room return air (yellow arrows) through evaporator coil cooling room air (blue arrows). Unconditioned outside air mixes with conditioned room air and discharges to room (green arrows) through supply air louvers.
