Drip edges have been in use for centuries, but we often take their quiet contribution to building performance for granted. While some designers resist using them due to their aesthetic impact, some critical components of the building enclosure will not function properly without them. This presentation will focus on the connection between drip edges and […]

Over the course of 14 years, Walsh Construction Company has been on a journey of learning and discovery regarding effective strategies to create airtight building enclosures. We have learned from our mistakes, learned from our partners and learned that air tightness is not just about the enclosure, but is heavily tied into mechanical system interface […]

Use of combustible building materials in wall assemblies increases the risk of fire in the built environment. The relationship between the weather barrier and NFPA285 compliance is often misunderstood. This course will cover the basics of the NFPA 285 test standard and the building code sections relevant to weather resistive barriers. It will also address […]

Blower door testing finally has an established market to analyze bulk data. Lets study this data collected over the past decade from over 1,000 commercial blower door tests and over 6,500 residential unit tests. Data will include pass and fail frequency, common leakage sources, infrared diagnostics, and more! Learning Objectives: Analyze pass and fail frequency […]

The 4 C’s—Clear, Correct, Concise, and Complete—form the foundation of effective technical and specification writing. Building Enclosure Consultants (BECs), however, may not be fluent in the language of specifications, often viewing it as a misunderstood second language. As a result, the work of specification writing becomes doubly challenging when collaborating with BECs. This session explores […]
