Today’s buildings are more complex than ever, incorporating multiple layers of materials, numerous trades, tighter schedules, higher performance expectations, and greater cost sensitivity. Unlike the simpler building systems of the past, modern buildings must provide precise temperature and humidity control, superior indoor air quality, energy efficiency, and protection against condensation and mold. Achieving these goals requires a well-designed and properly constructed building enclosure.

While material and assembly performance is often based on published product data, that performance can be significantly reduced—or lost entirely—without effective transitions, terminations, and flashing details at critical interfaces. This presentation examines the evolution of building enclosure design and materials, with a focus on roof-to-wall transitions. Attendees will review ABAA Roof-to-Wall Conceptual Details alongside real-world case studies and performance testing, comparing historic and current detailing practices. The session will also explore how modern lightweight construction impacts the integration of roofing and wall assemblies, construction sequencing, scheduling, and overall building performance.

Learning Objectives:

1. Building Enclosure History and Design Principles: Participants of the session will review building construction practices of the past and present, specifically wall construction and roof construction. Building Science principles will be overlaid to better understand the importance of proper interfacing.
2. ABAA Roof to Wall Conceptual Details: Review details and discuss key aspects for interfacing strategies
3. Constructability and Construction Sequencing: Participants will review how performance-based interfacing details impact constructability and construction sequencing.
4. Case Studies: Project examples will be reviewed.

Adam Ugliuzza brings 18 years of engineering experience focusing on building science and the building enclosure construction industry. Discipline expertise includes building enclosure consulting and commissioning services for new and existing construction, in addition to forensic investigations to determine root cause of building performance issues. He also brings industry leading expertise in large building whole building airtightness testing, which is at the forefront of high-performance building construction. Adam continues to work on projects across the United States and abroad providing professional building enclosure consultation in both the residential and commercial space for all types of construction, ranging from multi-family wood/timber framed buildings to high performance institutional/healthcare facilities to high-rise construction. Through this experience, Adam brings a unique approach to building enclosure consulting and testing, concentrating on enclosure interface coordination in design and construction phases of the project that overlays a holistic approach, critical to achieving high performance building construction; the goal to help ensure all the materials, systems, and assemblies are properly connected to provide continuous environmental control. His extensive testing knowledge allows him to be deliberate and methodical in his approach to interweaving functional testing to verify performance.

Adam is also active in many industry associations including Air Barrier Association of America (ABAA), Passive House Institute US (PHIUS), Construction Owners Association of America (COAA), United States Green Building Council (USGBC), etc. and has co-authored numerous technical papers, guidelines and standards; fundamental to an industry leading professional.
