Today, I feel very in tune with this podcast’s stated mission:
 
Building HVAC Science covers a broad array of topics in building science and HVAC diagnostics, as well as human comfort, health, and safety….; this show will take a deep dive into all things that relate to buildings and people in the built environment.
 
I was very fortunate to interview Dr. Joe Allen, an esteemed Indoor Air Quality researcher, presenter, and author, as we covered what Joe has observed and educated us on regarding the collision between two disciplines: building science and health science.
 
Joe shares his observations, strategies, and tactics that are moving us toward an era where buildings go beyond doing no harm to occupants but focus more on maximizing the benefit to the occupants.
 
Joe joins the growing list of people on this podcast who talk (all or in part) about indoor air quality or healthy buildings: Dr. Stephanie Taylor, Dr. Bill Bahnfelth, Joe Medosch, Larry Zarker, Nate Adams, Jason Earle, Cheryl Cieko, Dawn Oggier, Brian Kennihan, Ereland Bolle, Casey Grey, Ray Wu, Ben Reed, Kaleb Saleeby, Steve Pascuzzo, Big Clive, Ty Newell, Dick Kornbluth, and Jaques Touillion, amongst others.
