In this episode host Christoph Lohr discusses structural and behavioral water waste with Jim Lutz, a retired researcher from Lawrence Berkeley National Lab. Jim details his career, focusing on water heater efficiency and plumbing systems, and explains how his research has shown the significance of structural waste in residential plumbing, particularly in hot water distribution systems. He emphasizes the inefficacy of low-flow showerheads due to structural waste and advocates for compact plumbing designs to enhance water and energy conservation. Jim also highlights the long-term impact of these decisions on building efficiency and conservation efforts.
