In this episode of the Building HVAC Science Podcast, hosts Eric Kaiser and Bill Spohn welcome Jesse Smith, a carpenter turned HVAC enthusiast. Jesse, who has written an intriguing article titled "Lies, Damned Lies, and Manometer Readings" for Asterisk Magazine, shares his journey from carpentry to specializing in high-performance building and energy retrofits. His early exposure to energy efficiency through his father's work, combined with his professional evolution amidst the housing bubble, laid the foundation for his deep dive into HVAC systems and home performance standards. Jesse discusses his experiences and challenges in HVAC, emphasizing the widespread lack of proper setup and calibration in the field, which he identifies as a significant issue affecting both indoor air quality and energy efficiency. His practical encounters, such as dealing with incorrect airflow measurements and learning about the critical settings of HVAC systems, underline his critique of what he sees as endemic incompetence within the industry. This incompetence, Jesse argues, poses severe risks not only to building efficiency but also to public health and environmental sustainability. The podcast conversation also delves into Jesse's broader concerns about the construction and HVAC industries' stagnation in productivity and innovation since the 1970s. He calls for better education and accountability in the industry to overcome these challenges. Jesse's perspective is that of an insider calling for systemic change, advocating for the adoption of better practices and technologies to improve building performance and, ultimately, contribute positively to societal health and environmental goals.   Jesse’s Linked in: https://www.linkedin.com/in/jesse-smith-59a54966/ The original article that drew our attention:   https://asteriskmag.com/issues/05/lies-damned-lies-and-manometer-readings   This episode was recorded in March 2024.
