In the latest episode of the Building HVAC Science Podcast, Eric Kaiser and co-host Bill Spohn welcomed guest Enrico Bonilauri, an architect originally from Italy now based in the U.S. Enrico shared insights from a comprehensive study comparing various building standards across 50 projects to evaluate energy efficiency and performance. He discussed the differences between international and American passive standards and the standard American building code, emphasizing the need for builders to adopt high-performance building techniques. Throughout the discussion, Enrico highlighted the challenges of aligning different building standards and introduced a scoring system he developed to assess various metrics like energy performance, air quality, and durability. He explained that the study took two and a half years to complete, involving detailed energy modeling to meet different standards. This extensive research aimed to demonstrate how passive building standards compare against others like Energy Star and the energy code, shedding light on the potential for energy savings and improved construction practices. Towards the end of the episode, Enrico spoke about the practical applications of the study, including training and educating American builders on passive building techniques through his company, Emu. He emphasized the importance of hands-on training and creating a community among builders and designers to share knowledge and improve building practices universally. The episode concluded with discussions on upcoming training sessions and the availability of Emu's detailed study reports for public access, encouraging a broader engagement with sustainable building practices.   Enrico’s Linked in: https://www.linkedin.com/in/enricobonilauri/ His business website: https://emupassive.com/ Link to the study:  https://www.dropbox.com/scl/fi/9b6yzoqsppr2jafbaptmq/Emu-PH-Report.pdf   This episode was recorded in April 2024.

EP164 Behind the Scenes at ACCA 2024: A Dialogue with Ed Janowiak (MARCH 2024)

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.
