Building enclosures not only convey architectural concepts, they also separate exterior and interior and control environmental loads – all while maintaining occupant comfort, long-term energy efficiency, and building performance. Selecting appropriate materials for opaque exterior wall assemblies, developing complete construction detailing, and testing and verifying the building enclosure are critical steps in delivering high-performance enclosures. Project teams have implemented building enclosure commissioning (BECx) on more projects as its popularity increases and industry organizations and government agencies consider the enclosure to help measure and verify installation against design intent and owner’s project requirements. In this presentation, we will discuss the relationship between construction systems and weatherproofing; explore design guidelines for wall assemblies; review code requirements and considerations, including energy and fire; and provide an overview of the BECx process, illustrated through case studies to demonstrate successes and lessons learned.

After attending this seminar, participants will be able to:

  • Learn how to select an appropriate weather-resistive barrier for opaque exterior wall assemblies based on project conditions.
  • Understand the importance of robust construction drawing details and specifications, as well as recommended detailing considerations.
  • Analyze a wall design with respect to code requirements, water penetration resistance, fire requirements, and energy performance.
  • Identify the scope of quality assurance provisions embodied in current standards, including ASTM, LEED v4, and Title 24.

Amy Hackney, P.E., LEED AP | Senior Principal, Simpson Gumpertz & Heger
Amy Hackney is head of SGH’s Building Technology division in Southern California, with extensive building enclosure engineering experience. Her primary emphasis is on new design building enclosure consultation. Her work addresses issues related to the integrity of glazing assemblies, opaque exterior walls, roofs, plaza decks, balconies, and below-grade systems. She has experience working with architects, contractors, and developers on a wide range of structures, including high-rise residential buildings, hotels, health care facilities, museums, stadiums, and commercial and mixed-use projects. Her experience also includes investigating existing building enclosures and waterproofing systems and repair and rehabilitation design of those components. Amy is the President of and on the Board of Governors for the Architectural Engineering Institute of the American Society of Civil Engineers (ASCE).
