The 2024 International Energy Conservation Code (IECC) fundamentally shifts how the thermal performance of building enclosures is designed and evaluated. In the 2024 IECC Chapter 4 Commercial Energy Efficiency, compliance now requires design teams to account for linear and point thermal bridging, as does ASHRAE 90.1-2022, which is incorporated by reference. This impact will notably change how design professionals consider typical building details like parapets, cladding attachments through continuous insulation, window perimeters, and more. Through a side-by-side review of previous and current requirements, this course will bolster design professionals’ understanding of the steps needed to address thermal bridges and how to incorporate these results in prescriptive path, performance path, and COMcheck compliance calculations. By examining the updated air leakage testing requirements codified in the 2024 IECC, professionals will learn to decipher whether whole-building air leakage is mandatory or if the air barrier design and verification approach will apply to their project. This course will explore the practical impacts of the new energy code requirements, reveal strategies for meeting compliance, and share tools that can help design professionals stay ahead in a rapidly changing energy code landscape. This course welcomes both new and experienced design professionals alike. Those with a basic understanding of building enclosure-related heat transfer and fundamental calculation methods will benefit most from this course....

Protected Membrane Roofing (PMR) assemblies have been widely adopted in low-slope commercial buildings since the late 1960s. Also known as the Inverted Roof Membrane Assembly or Upside Down / Inverted Roof, PMR assemblies move the waterproofing membrane from the top of the roof assembly to the surface of the structural deck. This simple design change provides several advantages over conventional roof assemblies that have their waterproof membrane fully exposed at the top surface. For architects, PMR assemblies present many opportunities to create innovative, sustainable, and efficient buildings. The most significant advantage is that PMR assemblies offer superior protection against water penetration, which reduces the likelihood of leaks and extends the lifespan of the roofing system. They also offer enhanced energy efficiency, from the strategic insulation layer placed above the waterproofing membrane. This course will also show how PMR assemblies provide ample opportunities for sustainable design integration. They allow for the creation of green roofs or Blue Roof systems, which provide environmental benefits like rainwater harvesting. With its proven record of reliability, PMR assemblies present a compelling solution for architects seeking innovative, sustainable, and efficient roofing option...

Air barriers are intended to block air and moisture from getting into the building. But frequent testing and thermographic imaging shows that one common source of building leaks is at or near air barrier failures.

Proper project-specific testing ahead of construction can help prevent these failures before they become costly. This course will review industry-recognized requirements and test methods specified for air barrier membranes. Participants will also learn how enhanced testing can measure long-term performance, giving you piece of mind before construction begins....
