BSC investigated a circa 1940 concrete cast in place warehouse that was converted to residential lofts in 2005.  There have been persistent water intrusion issues at the exterior walls; BSC was asked to determine the cause of some still-unsolved leaks.One issue was determined to be not water leakage, but interstitial (within the cavity) condensation. This problem manifested as water leakage at the window head return; opening the cavity showed pooling water, coming from the floor above. The floor above was finished with an insulated steel stud wall offset from the concrete wall by 8 inches,...

The Country Club is a circa 1920 mass masonry eight-story building, with exterior walls composed of either brick cladding or stucco rendering over brick, with a hollow terra cotta block backup wall.   BSC investigated the blistering of an elastomeric coating which was recently applied to the existing stucco, in an effort to address bulk water intrusion issues.  The failure of the elastomeric coating was unexpected, given that it is designed to allow drying ("breathe"), and permit the escape of water.  The pattern of the blistering was examined, and correlated with exterior bulk water drainage...

Designed for a net-zero energy development, the single-family houses reflect the traditional New England style that the developer strives to achieve. Intended as affordable and market-rate units, the houses offer between 1,600 and 1,800 square feet and feature 3 and 4 bedrooms, respectively. The houses are designed with a slab-on-grade foundation, which is offset by spacious living areas and bedrooms as well as ample storage space. An option to include a basement in the design is offered to future homeowners. The key characteristics of these houses include super-insulated double-stud walls...

Green Water Tower is a thirty-eight-story three-tiered mixed-use tower in downtown Austin, Texas at the former site of the Thomas C. Green Water Treatment Plant.  The mixed-use building designed by Solomon Cordwell Buenz is bounded on the south by the Colorado River and has approximately 440 apartments and over 40,000 square feet of office and retail space.Building Science Corporation worked with the design team through the Design Development and Contract Document stages to mitigate the risk of moisture related failures in the building enclosure and meet the project’s energy goals.  BSC...

Hanover CambridgePark luxury apartments were constructed in a podium style construction with 4, wood-framed stories over an elevated concrete deck.  Located in North Cambridge, near the MBTA’s Red Line Alewife station, the complex offers one- and two-bedrooms units, and many high-end amenities including two courtyard spaces with a pool.  As part of an integrated team, BSC was brought on board as the enclosure consultant in the Design Development phase of the project.  BSC evaluated plans and details with a focus on durability and energy performance, and provided feedback on the identified...

BSC performed a field investigation on moisture problems at a one-story, steel-stud building with EIFS walls, and soffit/fascia covered by a standing seam roof system. In cold weather, icicles were forming at cracks in the soffit and there were water stains on the exterior of the windows just below the soffit. It was observed that the space within the soffit was conditioned volume that was directly connected to the interior and, as is typical of a medical building, it was pressurized. This situation would result in substantial exfiltration through any air barrier gaps. A 3/8" gap in the air...

Historic New England owns and/or manages historic properties scattered throughout five states, with the goals of preserving and presenting New England heritage, and educating the public.  They have consulted Building Science Corporation on multiple projects, typically looking at the goal of reducing energy consumption while without the use of irreversible methods on the historic fabric of the building, as well as not compromising durability.  All of these projects involved a field evaluation of the building, followed by analysis and recommendations.The Pierce House was built circa 1683 and is...

Since opening in 2003, this medical facility had experienced water intrusion problems. In 2008, when evidence of mold at the base of the drywall and rust within the steel framed wall was observed along some exterior walls, BSC was retained to do a thorough analysis of the enclosure and to identify not only the reason for the current problems but to point out other potential problems as well. Using observations provided by the client, review of construction drawings, and on-site analysis, BSC identified multiple pathways for water intrusion into facility. BSC prepared a report describing these...

BSC investigated a 5 year old wood-frame indoor pool building in Climate Zone 6A. This work was prompted by reports of staining of the exterior siding; disassembly of the walls revealed substantial rot of the sheathing and the wood framing. BSC was asked to determine the cause of the damage, and provide recommendations for build-back in a moisture-safe manner. Exterior infrared inspection revealed warmer areas surrounding the window, especially at the sill/corner area. The wall was disassembled, revealing substantial decay of the OSB wall sheathing and framing (outboard side). Damage...
