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 help translate what the latest changes to building codes mean for opportunities in wood construction, the American Wood Council (AWC) has introduced four new standards that are adopted by reference in the 2015 International Building Code (IBC) and the 2015 International Residential Code (IRC). This article examines the new Permanent Wood Foundation (PWF) Design Specification.
The 2015 edition of the ANSI/AWC Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings provides guidance for wood-frame construction in residential as well as commercial structures that fit within its scoping.
Historically, glazing has been used to provide light and ventilation in building walls as its primary function. In contemporary buildings, specialized glazing can provide numerous other functions, including fire-resistance.
Designing proper construction details is an important part of architecture and engineering practice that involves more than just a grasp of building technology. If designers are not also alert to market conditions, then their details—no matter how elegant—can be ineffective and hinder the pace of a project. Overlooking the complications surrounding the specification of adhesive anchors is a prime example, as recent code changes regarding their use threaten to stall building projects in some of the United States’ largest jurisdictions.
