Learn how ultrasound is used to revolutionize how we detect and quantify air leaks in buildings. Empowering contractors and retrofitters to proactively manage airtightness, reducing costly rework and improving building performance. Understand how ultrasound is aligned with blower door and thermographic imaging results, and its unique capabilities to quantify airflow and rank leak severity. No prerequisite knowledge needed.

Speakers
Daniel Dobrowolski is Director of the Durham Institute of Research, Development, and Invention (DIRDI); Chief Scientific Advisor to the Chairman and Head of Research at Coltraco Ultrasonics. At Coltraco, Daniel has led numerous scientific research teams and, in 2020, invented instrumentation to monitor negatively-pressurized NHS ICU wards preventing airborne viral spread between wards. Further development enabled the accurate monitoring of airtightness and energy loss in the Built Environment to reduce carbon emissions associated with the heating and cooling of buildings. After a master’s degree in theoretical physics at Durham University with a dissertation on the computation of scattering amplitudes in particle physics, Daniel read Intelligence & Security at Cambridge and has since published papers with the Royal United Services Institute and the Atlantic Council. In 2024, Daniel achieved a reservist commission at the Royal Military Academy of Sandhurst. Daniel also serves as the Deputy Director of the Centre for Underwater Acoustic Analysis (CUAA).
John Knapp is the Co-Founder of Source 2050, the leading online marketplace for energy efficient and high performance building products. An intellectual property attorney by training, John became a Passive House advocate a decade ago after renovating his home in Brooklyn to be the first Passive Plus certified project in North America. He is also a founding advisor to the Passive House Accelerator.
Lessons Learned
1. Understand how effective air sealing, as facilitated by ultrasound technology, contributes to healthier indoor environments by reducing pollutants and enhancing air quality.
2. Analyze the role of ultrasound in identifying air leaks, which is vital for ensuring the safety and compliance of buildings with mandatory air pressure tests.
3. Introduce the concept that properly sealed buildings not only enhance energy efficiency but also support the welfare of occupants by creating comfortable and stable living conditions.
4. Articulate the importance of leveraging ultrasound technology in building performance as a proactive measure to avoid costly rework and improve overall energy efficiency.
