“Till Death Do Us Part”: Preventing a Facade and HVAC Divorce When It Comes to Air Barrier Performance

Avoid Catastrophic Mold and Moisture Problems in Hot, Humid Climates
Due to Air Barrier Standard Confusion

New Webinar Addresses the Inherent Risk of Mold and Moisture Problems in High-Performance Buildings

The inevitable is about to happen: high-performance building objectives are emerging as the new normal across the country.

For some design and construction firms, this will mean business as usual. For others, however, the change will be cataclysmic, resulting in a much higher risk of mold and moisture-related building failures.

While high performance standards may not be fully adopted by all model building codes or jurisdictions, they will become the de facto standard of care. On the surface, this certainly has many redeeming aspects, such as mandating better-performing, more energy-efficient buildings. But it begs the question: will buildings actually get better or […]

New Online Course Demonstrates How to Design and Construct High-Performance, Low-Risk Buildings While Avoiding Catastrophic Mold and Moisture Problems

The mission of designing high-performance buildings that promote sustainable objectives has led to new success stories but has also revealed vulnerabilities for potential mold and moisture failures.

The interaction between a building’s HVAC system and envelope creates an unusually high-risk area. Any deficiency in either system can cause dramatic, building-wide moisture and mold problems. Through the emergence of high-performance buildings combined with the use of certain new green products, designers and contractors have inadvertently created high-risk buildings when, in fact, the goal should be to develop high-performance buildings with the lowest possible risk of failure.

There is no building envelope which a […]

LBFG Publishes “Waking the Dead” Article

LBFG experts George Dubose, CGC and Donald Snell, PE, CIEC published an article in the Spring/Summer 2016 issue of the National Association of Subrogation Professionals’ Subrogator magazine.

The article, entitled “Waking the Dead: How to Subrogate a Zombie Defect Building Failure”, takes a look at the new edge in risk management concerns for the building industry.

Here’s an excerpt:

“Buildings with hidden flaws, known as ‘zombie defects’, are increasingly experiencing acute, massive failures that lead to extensive moisture and mold damage. This, in turn, results in complex insurance claims and confusing subrogation headaches for the industry.”

The Incredible Predictability of Building Moisture and Mold Problems

Suppose there was a tool that could predict the likelihood of whether your building would fail. What if this tool could also provide you with information to help decrease risk factors? Liberty Building Forensics Group (LBFG) for the National Council of Architectural Registration Boards (NCARB) believe we have created that tool.

NCARB, which represents nearly 40,000 architects worldwide, is launching a new online continuing education monograph that captures the updated version of a formerly released manual and provides CEU credits for registered architects. The monograph contains moisture-prediction guidelines adapted from a mold and moisture manual developed for the Disney Corporation and […]

Fear Factor: Mold Returns Despite Costly Repairs (Was It Rain Or Was It Air?)

Here’s a building owner’s real fear factor: your building is found to have mold and moisture problems. Diagnostic tests lead to a complete rebricking of the exterior, only for the same mold problems to return the following summer. That’s scary.

How could the repair have been so far off from what was actually the problem?

Most often this is a result of not paying close enough attention to mold and water damage patterns and, as a result, misdiagnosing – or only partially diagnosing – the root problem. This is especially common in cases where a building falls victim to complex moisture problems […]

Has Coastal Zone Hotel Construction Become the Twilight Zone for Mold & Moisture Control?

Just months after completing refurbishment on a 300+ room resort, the owner of the luxury coastal vacation resort began to wonder if he had entered into the twilight zone when mold and moisture problems suddenly emerged in numerous guestrooms.

He was perplexed that this problem was only now cropping up despite the fact that he had owned the property for over 25 years. Never in all that time had he ever experienced moisture-related issues. Why was the problem occurring at this point? What was different?

This scenario is all too familiar to building forensics experts at Liberty Building Forensics Group (LBFG), who […]

Strange Bedfellows: Common Ground for Takata Airbags and Moldy Buildings

Airbag maker Takata made headlines recently as a seventh airbag-related fatality forced the Japanese company to announce the largest auto recall in history.

Takata had initially recalled faulty airbags in 18 million vehicles, believing the malfunctions to be linked to cars in hot, humid climates. Although the airbags were failing in other climates as well, they interestingly had higher failure rates when humidity and moisture were involved, drawing a remarkable parallel with the root cause of many building failures.

Building forensics experts have long known that specific climates require a specific approach to building design and construction in order to avoid failure. […]

Coming of Age: How to Keep Your Next Major Hotel Upgrade from Causing Major Moisture Problems

Hospitality owners and property managers across the country and around the world are approaching (or have already observed) a birthday many don’t want to celebrate.

Their buildings, typically 30-35 years old, are in need of undergoing what the industry refers to as “major upgrades” falling under the regularly planned work cycle. Examples include timely upgrades for building envelopes and HVAC infrastructure that are not part of the normal refresh cycle.

In the process, owners and managers are discovering that what may have been previously acceptable in terms of what constituted a successful building review is no longer considered acceptable because of building […]
