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.
