ENVELOPES, ENERGY AND STEEL
How Structural Choices Affect Energy Use

CONTINUING EDUCATION - 1 PROFESSIONAL DEVELOPMENT HOUR

OUTLINE

The term “building envelope” was not very common a few decades ago, but today it is an important consideration in any structure that has conditioned space. Since most cold-formed steel engineers work on these types of buildings, designers need to understand how their choices affect flows of air, moisture and heat through the building envelope. Industry veteran Don Allen will start with the basics: air/vapor/moisture barriers, why they are important, and how the selection of framing makes a big difference in how these barriers perform. Then he will dig deeper into some of the common detailing mistakes that lead to poor energy performance – and show you how these mistakes can be avoided. This presentation will touch on the broader goal of net-zero building carbon emissions, and how cold-formed steel can play a major role in long-term building performance and energy use, while at the same time providing excellent structural performance and durability. Principles from the recently released AISI S250, North American Standard for Thermal Transmittance of Building Envelopes with Cold-Formed Steel Framing, will be included.
