Comments Off on 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?

Comments Off on 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

This is part 2 of 2. LBFG recently worked with a midwestern medical facility experiencing buildup of frost and ice in above-ceiling spaces and clerestories during winter months two years after construction. The frost/ice eventually melted, causing damage and leaking into occupied rooms below. LBFG discovered the causes to be an improperly designed air barrier

This is part 1 of 2. The 1940’s play “The Iceman Cometh” examines the dangers of an illusory life. Fortunately, when it comes to building science, there’s no need to live under illusory pretensions about whether a building will fail or thrive.

Comments Off on How to Make Your Next Air Barrier Prevent Building Mold and Moisture Failures, Pt. 1

This is part 1 of 2. After seeing numerous high-level examples of building failures due to air barrier defects, Florida-based Liberty Building Forensics Group (LBFG) is warning that air barrier goals set by architects aren’t always achievable by contractors and can even lead to disaster. Building moisture that leads to water damage and mold is

This is part 3 of 3. The solution to the clash between brand standards and regional best practices is threefold: 1) Design professionals and contractors need to assert that specific requirements for hotels in certain climates cannot be violated if hotels are to avoid mold and moisture problems. 2) The brand must accept that certain

This is part 2 of 3. The inherent flaw in the situation is that brands claim their standards are only guidelines. They believe the designer or contractor on site is ultimately responsible for interpreting how the regional climate might impact brand standards. Ideally, the design and construction teams who are responsible for making sure everything

This is part 1 of 3. Florida-based Liberty Building Forensics Group® (Liberty), a leading building forensics firm that has solved some of the world’s largest and most complex building moisture and mold problems, has a warning for unsuspecting hotel design and construction teams. Rigid adherence to brand standards without factoring in specific regional and climatic

This is part 2 of 2. Liberty Vice President George DuBose explained that the average building age of a prolific generation of hotels in the United States is currently 25 or 30 years. “This means the statute of limitations for original designers and contractors is long gone,” he said. “As a result, the last recourse

This is the third of four posts in a CPVC piping failures series by Donald B. Snell, PE. Potential Contaminants on the Inside of the Pipe The use of metal piping in domestic water, condensate drain piping, and fire sprinkler applications has given way to plastic composition piping for the previously mentioned advantages.

Comments Off on OWNER Caution! – Why Are Designers Not Aware of CPVC Failures? (Part 2)

This is the second of four posts in a CPVC piping failures series by Donald B. Snell, PE. Causes of CPVC Failures When CPVC failures do occur, most frequently they are due to contamination issues and minor stresses imparted on the pipe. (See article by Duanne Priddy on Why Do PVC & CPVC Pipes Occasionally Fail?.) Contamination issues

This is the nineteenth and final post in a series by J. David Odom (ASHRAE), Richard Scott (AIA/NCARB/LEED AP), and George H. DuBose (CGC). It was first published as a mini-monograph for NCARB (National Council of Architectural Registration Boards). To summarize our recommendations, we believe that the following should occur in an effort to enhance
