Understanding heat, air, and moisture control

Many designers and specifiers understand controlling air, vapor, and thermal transfer helps mitigate moisture problems within the building envelope. Moisture accumulation is a performance adversary that can lead to structural deterioration, finish damage, organic growth, and reduced building longevity.

To Test or Not to Test…? A guide to field quality control

When properly applied, tests can yield valuable insight into the installed performance of systems, aid investigators in determining the cause of a failure, or help to determine if a product is performing to its intended level. However, when improperly applied, many tests and standards can produce misleading results, improper conclusions, and lead to unnecessary repairs or remediation efforts. Within this context, the article takes an in-depth look at roofing assemblies, along with glazing, masonry, and air barrier assemblies.

Avoiding Problems in Aquatics Facilities: Atypical design for atypical buildings

There are many issues to consider when designing a natatorium, including the choice of structural systems, building enclosure components, mechanical systems, and the operation of adjacent spaces in multi-use facilities. The intent of this article is to discuss the typical problems that the authors have investigated in over a dozen existing natatoriums and provide practical guidance for avoiding those problems through diligent and careful design and construction.
