Upcoming Passive House Webinars to Focus on Testing, Finch Cambridge & Avoiding Common Mistakes


There are three (free!) upcoming webinars on Passive House that will be hosted by either Mass Save or NESEA (Northeast Sustainable Energy Association). Though the presenters are based in Massachusetts, the issues about building science and Passive House that they will discuss are universal. Information about the webinars and links to register can be found below. We hope you take the chance to sign up!

Webinar: Passive House Verification: What to Expect When You Are Expecting a Passive House

While some requirements, such as blower door testing, are generally well-understood by Passive House designers, others are less obvious. While it is the job of the Verifier, not the Designer, to perform all required tests and inspections, Designers can benefit from an understanding of which specific parts of their design will ultimately be tested. These testing and verification requirements are both explicit in the PHIUS standards and implicit in several third-party programs that are required by PHIUS. By gaining a basic understanding of these requirements and additional certifications, Designers can position their projects for a higher degree of success within the Passive House system.

Webinar: Homeowner’s Rehab: Finch Cambridge

This building will be the first affordable housing multi-family project in Massachusetts to certify to Passive House Standards. Join NESEA to hear from Tom Chase of New Ecology, James Petersen of Petersen Engineering, and Michelle Apigian of Icon Architecture to hear what they’ve learned and incremental costs. As a Passive House project with a 105 kW PV array on the roof, it will also be one of the most operationally energy efficient buildings in Massachusetts. Currently in the final months of construction, this project has many important lessons to teach teams interested in Passive House certification.

Webinar: Common Passive House Mistakes and How to Avoid Them

Designing a Passive House is not easy! Yet maybe it is actually the easy part when considering the entire design and construction process. Drawing ideal details in the controlled environment of a comfortable office are very different than the real challenges encountered. Weather, sequencing, materials, low skilled workers, apathy, inertia, as well as common mistakes all conspire against achieving Passive House certification throughout the many months of construction.

This presentation focuses on helping passive house designers, builders, and developers avoid common mistakes on multifamily residences. It will illustrate where corners are often cut and seemingly innocuous decisions that can have a substantial ripple effect through the rest of the project. Covered topics include material continuity and sequencing at the thermal and airtight boundaries, substitutions and unintended consequences, specifications and coordination. The lessons presented were learned on actual projects and are intended to illuminate common pitfalls in order avoid them.
