Joint AIA and ASHRAE MeetingFebruary 16th at Zimmerman Architectural Studios and Harwood Engineering office.

Moisture Problems in Buildings

Moisture problems are the most common problems in buildings.Excessive moisture or uncontrolled moisture is a component of many IAQ problems.It is much less expensive to prevent moisture issues than it is to correct the problems after they occur.The first step in the solution of a moisture failure is external (rain or ground water leakage) or internal (condensation).Many buildings have a combination of both sources.Humidified buildings (residential, commercial and industrial) have unique solutions.Indoor pool buildings and trash-to-energy plans are two types of structures that frequently have condensation stains, rot and corrosion resulting in lawsuits.Buildings in hot-humid climates such as the U.S. Gulf Coast are just as likely to have mold and mildew as in buildings along the Canadian border.Is the HVAC system a part of the problem or a part of the solution?Mr Lotzhas seen both.
