About this episode

Edward Louie joins Bill Spohn to discuss the importance of curiosity and details in HVAC performance and building energy research.

Quotes from the episode: "Comfort isn't just about air temperature—it's also about the temperature of everything around you." "If it's difficult to maintain, eventually it simply won't be maintained." "Stay curious about your built environment. Pay attention, ask questions, and keep learning." Edward Louie of Pacific Northwest National Laboratory joins Bill Spohn for a thoughtful discussion that goes far beyond heat pumps. Known throughout the building science community for his data-driven LinkedIn posts and willingness to challenge conventional wisdom, Edward shares how curiosity has shaped both his career and his approach to research. From growing up in a drafty, inefficient home to conducting cutting-edge research on building energy, he explains why asking better questions often leads to better buildings. The conversation explores what really determines HVAC performance in the field. Edward discusses why airflow and proper system sizing matter more than headline efficiency ratings, how radiant temperature influences comfort just as much as air temperature, and why installation quality remains the industry's biggest opportunity for improvement. He also shares practical…
