  Modern high performance buildings demand more than independent envelope components. They require a coordinated air control strategy that begins with the details to the final building air leak testing. This course examines the role of continuous air barriers in improving energy efficiency, durability, and occupant comfort in commercial construction. Participants will explore how air leakage increases condensation risk, reduces thermal efficiency and impacts long-term building performance.

  This course will review best practices for detailing critical transitions such as roof-to-wall and wall to below-grade connections, where discontinuities often lead to failures. Special attention will be given to vapor permeable air barrier systems and their ability to maintain airtightness while supporting drying potential within the assemblies.

  Through discussion of real-world projects across mission-critical facilities, large-format industrial buildings, multi-family housing, and commercial construction, attendees will learn how integrated, permeable enclosure strategies support long-term resilience, effective moisture management, and reduce building failure risk.

  Learning Objectives:

  1. Identify best practices for maintaining air control at critical transitions, including roof-to-wall and wall-to-below-grade connections.
  2. Cover how air leakage impacts energy performance, durability, and occupant comfort in commercial buildings.
  3. Discuss how vapor-permeable air barriers support drying potential while maintaining airtightness in high-performance enclosure design, including data centers, multifamily, and commercial buildings.
  4. Identify common breakdowns in communication and sequencing between trades that impact air barrier continuity and explore approaches to improve coordination at critical transitions.

  This presentation examines the role of concrete tile roof systems as a high performing component of the building enclosure, with a specific focus on energy performance and solar compatibility. While roofing discussions often center on aesthetics or installation, this session shifts the focus to how roof system design influences heat transfer, peak energy demand, and long-term operational costs. Using data from industry and national laboratory studies, including temperature and energy use comparisons between tile and shingle roof systems, the presentation will explore how ventilation, air space, material density, and thermal behavior affect building performance. Attendees will gain a clearer understanding of how tile roofing systems interact with solar installations, support energy code requirements, and contribute to durability, occupant comfort, and reduced energy demand across residential, multifamily, and institutional projects.

  Learning Objectives:

  1. Describe how concrete tile roof systems influence heat transfer, attic temperatures, and overall building energy performance.

  2. Explain how ventilated tile roof assemblies, including air space and airflow strategies, contribute to reduced peak energy demand.

  3. Discuss how concrete tile roof systems serve as an ideal material when considering compatibility with rooftop solar systems.

  4. Compare roof system thermal performance curves and understand how timing and magnitude of heat gain impact energy costs and grid demand.
