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.

This article for construction specifiers assesses why and when to consider temporary buildings as an alternative to permanent construction, renovation, or leased existing space. Decision-making criteria, including category options, financial and site considerations, as well as technical information on energy-efficiency, usable space, roof loads, and wind ratings are examined.

Discussing specification writing and documentation details can be challenging, but the right set of specifications is a key component in the process to deliver a successful project. It is crucial the specification writer understands the intent of how systems will operate and how systems relate to each other. This is getting even more important as new buildings are getting more complex and have loftier energy efficiency goals. This article describes the most important aspects of construction specifications to ensure a good outcome for energy efficient buildings.

Testing Glazing in the Field: Performance Classes

Up until the 2008 edition of American Architectural Manufacturers Association/Window and Door Manufacturers Association/Canadian Standards Association (AAMA/WDMA/CSA) 101/I.S.2/A440, North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS), there were five performances classes of windows with differing requirements for test pressures, allowed leakage rates, and other variables. This sidebar discusses the current four types, and their minimum performance grades.

Laboratory testing of fenestration products to the North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS) verifies the performance of a specimen of the fenestration product itself. How can one be certain the specified performance will be realized after installation? When properly applied, field testing can be a useful way to verify actual installed performance during construction and prior to occupancy of a building. The key is testing in conditions that accurately simulate the real-world environment and ensuring that the appropriate test method is applied to the specific installation.
