Continuing our February focus on Airtightness, this session will explore the use of Background-Oriented Schlieren (BOS) photography as a real-time building leakage visualizer. Sealing air leaks in building enclosures is key to saving energy, enhancing indoor comfort, and improving durability. However, pinpointing these leaks can often be challenging and time-consuming. In this session, Philip Boudreaux, R&D staff member at Oak Ridge National Laboratory, will discuss the principles and development of a fast, affordable method to locate air leakage in building envelopes using BOS photography. This innovative technology provides a non-invasive, efficient solution to identify leakage in real-time, supporting better energy efficiency and long-lasting performance in building designs.

Philip Boudreaux, who holds a B.S. and M.S. in physics with a focus on optics, will share his extensive research experience in building energy efficiency, from deep energy retrofits to moisture durability of envelope components. His current work focuses on applying non-destructive testing methods to ensure efficient and durable building envelope performance.

This free presentation will take place on Wednesday, February 26th at 9am PT / 12pm ET and will be followed by a lively Q+A session. Don't miss this opportunity to learn from an industry leader and engage with the PHA community. See you there!
