Comments Off on The Incredible Predictability of Moisture Problems

This post by David Odom is part 1 of 3. Suppose there was a tool that could predict, before a single penny was spent on construction, the likelihood of whether your building would fail. Not only that, but this tool could also provide you with enough information to make significant design changes that would dramatically

This post by Don Snell is the third in a series of four examining the relation of moisture building assessments and building science as a component to design, construction, and commissioning. The tenant, in an attempt to achieve more comfortable space conditions, will typically lower the thermostat set-point, causing these spaces to cool further while

J. David Odom Liberty Building Forensics Group, LLC. The Problem Two of the most difficult buildings to design and construct without experiencing severe moisture problems are: 1). Refrigerated buildings in hot, humid climates, and 2). Pool buildings in very cold climates. Inherently, nature never intended for these buildings to exist in these climates with such

Comments Off on Removing the Mask from Hidden Moisture Problems in Buildings

Removing the Mask from Hidden Moisture Problems in Buildings   Shortly after construction was completed, a seven-story, four-star hotel in Charleston, South Carolina, developed severe moisture related problems. These problems included deteriorated wall components, mold, and significant corrosion. The investigators attributed the problems to rainwater intrusion through the hotel’s exterior brick veneer. Following that diagnosis, the hotel
