Advanced Air-Leak Detection with the Coltraco Portascanner

John Knapp, co-founder of Source 2050, sat down with Bernard Hornung, the Head of Built Environment at Coltraco Ultrasonics, and Kristoff Irwin, principal of Positive Energy, for an episode of Positive Energy’s The Building Science Podcast. 

The conversation centered around a “potentially game changing technology that impacts the ability to confidently deliver Passive House air quality control layers” – the Coltraco Portascanner, available at Source 2050. This innovative new product is a simple, noninvasive instrument to quickly check for air leaks.

What makes the Portascanner so revolutionary is that it allows you to test for air leakage without pressurizing your building. It is useful throughout construction because it can be used anytime, without having to move anything on your job site or performing a full blower door test. Utilizing ultrasonic sound, the Portascanner allows real-time testing of your project’s air barrier.



As Bernard Hornung aptly notes, one of the largest barriers to entry into the Passive House world is the fear of failure. Utilizing the Coltraco Portascanner removes that fear. By measuring air permeability values before a blower door test is conducted, there is no need to worry that your Passive House project might fail that mandatory test for Passive House certification.

Along with a deep dive into how the Portascanner works, John, Bernard, and Kristoff discuss the origins of Source 2050, how innovative solutions can disrupt the market side of building science, the importance of Passive House globally, and the creation of the Coltraco Portascanner.
