Building America Meetings

Photo of people watching a presentation on a screen the foreground shows a person's hands taking notes on a notepad.The Department of Energy's (DOE) Building America program hosts open meetings and webinars for industry partners and stakeholders that provide a forum to exchange information about various aspects of residential building research.

Current Webinars

The Building America program continues its webinar series into 2016! Each free webinar will offer information about the latest advances in residential building technologies and practices, presented by Building America research team and national laboratory experts.

Stump the Building Chump: Joe Lstiburek
Time: November 29, 2016, 3-4 p.m. EST

This new webinar series from the DOE Building America Program challenges professionals in the residential construction industry to ask building science questions that stump the building science experts! We want to know what problems are most vexing to you and your teams. It's our program goal to help provide solutions – or develop them where they don't already exist.

Our first expert is Dr. Joe Lstiburek, the founding principal of Building Science Corporation. Can you stump more than 30 years of industry expertise?

Submit your questions to We will feature the best questions during a webinar with our experts where they will answer your questions, and provide resources to help you solve the toughest building science challenges.

Your questions should be clear and concise, and should focus on challenges related to the building science of achieving high levels of energy performance in new and/or existing homes.

Air Sealing Best Practices and Code Compliance for Multi-Family Area Separation Walls
Time: December 15, 2016, 1-2:30 p.m. EST

For more than 20 years, the DOE Building America Program has been partnering with industry to bring cutting-edge housing research on energy efficiency to the residential building industry and the public. This webinar will provide an overview of area separation wall assembly construction in multi-family buildings, air sealing methods, and code compliance requirements.

Air sealing of area separation wall assemblies is an identified barrier that limits the ability of builders to cost effectively achieve higher energy efficiency and quality levels in multi-family housing. Area separation wall assemblies that are tested and certified by UL have not been designed or tested for air tightness, and air leakage through these assemblies can be a barrier to achieving air leakage limits mandated by the International Residential Code (IRC) and International Energy Conservation Code (IECC). The 2012/2015 IECC mandates 3 ACH50 in climate zones 3-8 measured air leakage requirements for all units within multifamily buildings.

The Leadership in Energy and Environmental Design (LEED) certification program, ASHRAE Standard 189, and ASHRAE 62.2 all have comparable compartmentalization requirements. Fire-resistance rated wall assemblies (or area separation walls) have been identified as the major source of difficulty in air sealing/compartmentalization. Building owners are challenged with constructing to significantly tighter levels, addressing compartmentalization issues between units, and adopting test procedures to prove compliance.

Current efforts to engage with UL may address these challenges and provide a mechanism for code acceptance of air sealing methods for these area separation wall assemblies. Join us on this webinar to learn more about these challenges and current efforts to resolve them. The speakers are: Pam Cole, Pacific Northwest National Laboratory Ari Rapport, IBACOS Robby Schwarz, EnergyLogic.
