EP203 Why Energy Isn't the Problem: Exploring Thermal Comfort and IEQ with Robert Bean (January 2025)

In this engaging episode of the Building HVAC Science Podcast, host Eric Kaiser is joined by Robert Bean, an ASHRAE Distinguished Lecturer and a renowned expert on indoor environmental quality (IEQ). Together, they explore the intricate relationship between architecture, thermal comfort, and HVAC systems. Robert shares insights from his extensive travels, observations of traditional architecture, and key lessons from his work in designing high-performance buildings.

The discussion highlights the critical distinction between energy efficiency and human comfort, emphasizing that discomfort often drives energy use. Robert explains foundational concepts like mean radiant temperature (MRT) and operative temperature and how they profoundly affect perceived comfort. He challenges common industry assumptions, such as relying solely on air temperature for thermal comfort, and advocates for a comprehensive approach that includes radiant, convective, and architectural solutions.

Listeners will gain practical advice on incorporating IEQ principles into design, leveraging tools like the ASHRAE Standard 55 and Robert's free eBook, Thermal Comfort Principles and Practical Applications for Residential Buildings. The conversation concludes with a call to prioritize human comfort in every aspect of building design and operation.
