Designerless Roofs: Who Has Liability for Faulty Design? September 15, 2026 From time to time, IIBEC chooses to republish articles from its archive that have continued salience in our changing industry. This article, published in 2005 when IIBEC was known as the Roof Consultants Institute, remains relevant specifically to building owners, contractors, and manufacturers in its discussion of the importance of hiring independent designers for building projects.
The D-I-P-F Curve: A Framework for Predicting and Preventing Roof Failures September 15, 2026 Reliability engineers use the P-F curve to chart the interval between the potential failure (P) point, when early warning signs appear, and the functional failure (F), when a component can no longer perform its intended function. In building enclosure consulting, however, many problems originate long before the P point. The D-I-P-F curve is a conceptual adaptation of reliability-engineering models that maps the roof’s life cycle from initial design decisions through the onset of measurable degradation and eventual functional failure. The D-I-P-F curve represents a conceptual framework synthesizing field data, failure timelines, and industry best practices, rather than a curve generated through numerical modeling.

Sealing the Deal: Avoid Getting Blown Away by the New IECC Air Leakage Requirements September 15, 2026 Any level of condensation in building enclosures that results in damage to a substrate constitutes a failure. If the presence of moisture due to condensation remains on organic surfaces for too long, this failure may be compounded by organic growth. These failures stem from either faulty design or installation and are always due to improper placement of one of the four control layers (air, water, vapor, or thermal), or a discontinuity in one or more of these control layers. Note that a discontinuity of a control layer could represent either a physical gap or an insufficient property, such as permeability or R-value. Technical Article
Failure Is Not an Option: Water Vapor and Healthcare Building Enclosures September 15, 2026 The risk of damage due to elevated humidity and condensation is present, to some degree, in all buildings. Some buildings are at greater risk than others, and a building’s risk is largely dependent on the surrounding climate and the use of the building (that is, expected relative interior humidity).

September 2026 From the CEO: Your Projects Are Award-Worthy. Show Them Off. September 15, 2026 The EBEC Awards have become a showcase for the best work in our industry. They demonstrate not only technical expertise, but also creativity, collaboration, problem-solving, and the value that independent consultants bring to the built environment. For consultants who toil to ensure the right recommendations are made before, during, and after a building is constructed or renovated, the EBEC Awards are a chance to put a spotlight on your fine work—and on the people who bring it all together. But time is running short.
