ASHRAE Journal Podcast

Join ASHRAE Journal Editor Drew Champlin as he interviews Max Sherman, Ph.D., Fellow/Life Member ASHRAE, about his award-winning article "IAQ Paradigms—The Next Generation.”  The conversation delves into the evolution of IAQ paradigms from ancient ventilation practices to modern standards, the role of ASHRAE in setting these standards, and the current paradigm shift focused on controlling infectious aerosols.

Join host Justin Seter, Associate Member ASHRAE, along with guests David Quirk, Member ASHRAE, Tom Davidson, Member ASHRAE, and Dustin Demetriou, Member ASHRAE, as they provide an update on the state of liquid cooling in data centers. Topics of discussion include research on liquid cooling resiliency, S classes and their importance, and standardization as it pertains to the rapidly evolving data center industry.

Join David Schurk and Mark Nunnelly as they discuss the unique dehumidification needs of hospital operating rooms. Topics of conversation include various system design options, how to strike a balance between compliance and occupant comfort, and general guidance for hospital design engineers.

Join ASHRAE Journal Editor Drew Champlin with guests Hwakong Cheng and Paul Raftery as they discuss reducing gas consumption, optimizing heating water systems and strategies for efficient morning start-up in existing large commercial buildings.

Wildfires have ravaged and devastated portions of California. ASHRAE recently released Guideline 44-2024, which is new guidance to mitigate the Impact of Smoke on Indoor Air Quality. Join host Drew Champlin live from the 2025 AHR Expo as he speaks with guests Abdel Darwich, Michael Gallagher and Randy Cooper on the effects of wildfire smoke and how to manage IAQ.

Join hosts Matt Walters, Associate Member ASHRAE, and Allison Hambrick, ASHRAE Journal Assistant Editor, for a discussion with 2024–25 ASHRAE President Dennis Knight about this term’s ASHRAE Society theme “Empowering Our Workforce: Building a Sustainable Future” and what’s next for the HVAC&R industry.

Many unanswered questions exist pertaining to high-availability operation of liquid-cooled IT equipment. Join host Justin Seter with guests David Quirk, Dustin Demetriou and Tom Davidson as they discuss the ins and outs of liquid cooling in data centers.

Join guests Amr Suliman and Marina Topouzi and ASHRAE Journal Managing Editor Kelly Barraza for this episode on occupancy in the built environment. This slice on building occupancy covers ventilation, indoor environmental quality, resilience, harnessing data on occupant behavior and how building efficiency and indoor conditions can be improved for a healthier, optimized built environment.

Machine learning (ML) is one of the defining technologies of our era, yet its application to HVAC controls is still in its infancy. Join ASHRAE Journal Managing Editor Kelly Barraza and Michael Berger, Member ASHRAE, as they discuss the use of ML in HVAC and how the technology can potentially optimize HVAC operations to reduce energy consumption.

Join Journal Editor Drew Champlin and Kelley Cramm, P.E., Life Member ASHRAE, as they discuss how HVAC factors into code requirements for elevators, the shift to machine room-less elevators and architectural coordination. 

Join experts David Schurk, Life Member ASHRAE, and Allison Bailes III, Ph.D., Member ASHRAE, as they discuss dehumidification needs in various climates and weather conditions as well as the differences between dehumidifying commercial, residential, industrial and health-care settings.

Join Journal Assistant Editor Sara Omer with guest Danielle Passaglia, Senior Mechanical Engineer at SmithGroup and author of Lucy’s Engineering Adventure and Lucy Goes Green as they discuss the impact of ASHRAE’s first book series for children and the intricacies of STEM-focused youth outreach.

Join Christian Taber and Michael Ivanovich as they discuss how the fans and blowers industry has evolved in recent years. Key talking points will include the progression of energy efficiency regulations on fans, ASHRAE Standard 90.1, large diameter ceiling and circulating fans, drives, and commercial and industrial applications of the technology.

Indoor air quality (IAQ) has consistently been a sticking point with facility owners and operators. Join Tina Brueckner and Jennifer Isenbeck as they discuss how engineers, industrial hygienists and other practitioners in the industry can follow ASHRAE Guideline 42 Enhanced IAQ for Commercial & Institutional Facilities to enhance indoor environmental quality for occupants.
