How Many CFM Does My Home Need? Ventilation Advice from HVAC Researcher Jeff Siegel

Spoiler alert: Corbett's wearing a retainer. Yes. You don't have to comment about it. Video forthcoming, as a matter of fact. Jeff Siegel is a superstar of HVAC research, and you can learn more from him in his original interview with me and at his research site. We're in the University of Toronto's rooftop climate chamber, shooting the bull about how many air cleanings per hour (aka air changes per hour, which is confusing to blower door folk) we should aim for in our living spaces.

How to Choose the RIGHT Windows for Your Home with Energy Modeling

FROM ‘HOME DIAGNOSIS’ SEASON 2 EP5: To avoid the extreme sales and marketing tactics we all see every day, we need science and measurement. Here's a quick tour through the evolution of homes (how homes work and why), the basics of energy modeling to compare how different home improvements will perform in the long run, and how the windows should install and function.

Every place is different, every home is different, every family is different- one size never fits all. To watch this entire episode about the science of doors and windows: https://homediagnosis.tv/episode-205-this-little-light-of-mine

Testing a Radon Mitigation System

Corbett teams up with Fantech's aerospace engineer and radon system expert Hamid Massali to prove the radon mitigation field works, and find out how much airflow the radon fan will need to exhaust to maintain safe air quality indoors.
