Comments Off on Military Housing Washes Out on New Air Barrier Standards

It remains to be seen whether new building code requirements that contain stricter air tightness standards based on energy efficiency initiatives are actually attainable. Buildings that passed former air tightness standards with flying colors just a few years ago would now fail dismally under more recent, aggressive standards in codes such as IgCC and IECC.

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

Comments Off on How to Make Your Next Air Barrier Prevent Building Mold and Moisture Failures, Pt. 2

This is part 2 of 2. “Building tightness is extremely important in increasing the drying potential of a wall,” said LBFG Vice-President Richard Scott, AIA. “A well-constructed building with a good air barrier helps the HVAC system pressurize the building with conditioned air, which increases its drying effectiveness. HVAC systems in warm, humid climates need

Comments Off on Is Big Data in Construction a Big Problem or Big Opportunity?

Massive construction projects often create major building forensic issues, requiring big data collection that quickly becomes a liability if not managed properly. If a quarter million data sets are to be used by a 40-member team, the data needs to be organized so as to efficiently accomplish goals and achieve solutions amidst large construction project

Comments Off on Liberty Building Forensics Group Completes Expert Witness Work for Pegasus Landings

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 recently completed an expert moisture-related consulting project for a building project called Pegasus Landings. An affiliated student-housing complex for the University of Central Florida, Pegasus Landings had

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 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

Comments Off on Air Barrier Testing at a Tropical Resort, Part 4

By Rick Scott, AIA This is part 4 of 4. Conclusions and Lessons Learned Test findings showed the difficulty of trying to achieve a very tight air barrier installation. While the resort specifications called for a very ambitious whole building air barrier performance target of 0.085 cfm/ft2 at 75 Pa, such numbers are almost meaningless

By Rick Scott, AIA This is part 3 of 4. Results of Air Barrier Testing After the test data was collected, it was analyzed to determine the air leakage rates in cubic feet of air (cfm) per square feet (ft2) of wall surface area. This analysis revealed that the building was leakier than predicted and

Comments Off on Air Barrier Testing at a Tropical Resort, Part 2

By Rick Scott, AIA This is part 2 of 4. Air barrier testing was also advocated to make sure the installation was meeting the building envelope air tightness goals set by the design team. One limitation of air barrier testing is that it needs to be performed when the building envelope is substantially complete, since

Comments Off on Case Study – Humidification, Pressurization, and Air Leaks Cause Frost and Ice Damage to a Medical Facility, Part 3

By Rick Scott, AIA This is part 3 of 3. Humidification Testing and Analysis Through quantitative analysis, it was determined that proper operation of the humidification system would solve the frost/ice problem without changing pressurization and/or replacing/altering the presumptive “air barrier.” Replacing/altering the specified vapor retarder to act as an air barrier would have required
