Corbett Lunsford - The Home Performance Worskshop & The Worlds Highest Performance Tiny House on Wheels!

February 15, 2019

Corbett Lunsford, wasn't a home performance expert- he used to play piano for ballerinas. In 2008, he learned a few things very quickly: construction is unbelievably messy, most pros are over-rushed and under-paid, and homeowners end up suffering in small ways, for their entire lives in a house. None of this has to be so- we can opt out of the whole thing with performance testing. His goal is to package building performance so it can easily be understood and used by professionals and consumers alike, for better buildings worldwide. In 2009, he started teaching pros through the Building Performance Workshop and he has hosted over 300 YouTube videos and 80 interviews for the Building Performance Podcast. He also wrote the book Home Performance Diagnostics: the Guide to Advanced Testing, and developed the APT Reports software tool.

In 2016 he and his wife Grace built the world's highest performance tiny house on wheels, the #TinyLab, and toured the US before settling down in Atlanta, Georgia. Along the way, they created the first TV series about home performance, Home Diagnosis, which airs on public TV across the U.S. Corbett, Grace, and their new baby went on a 13,000 mile, 34-city U.S. Tour from April 2016-January 2017 in the world's highest performance tiny house on wheels, the #TinyLab. Their mission was simple: to revolutionize the home market by teaching consumers and contractors alike to use scientific testing to prove the work gets done to quality standards. Each city on the Proof Is Possible Tour was sponsored by a local company that shared the passion for empowering homeowners and changing the game. Along the way certain cities shared in filming of the couple's TV show Home Diagnosis. They invited over 7,000 strangers into their home on the tour, and now live in Atlanta, Georgia.

David B. Corry, M.D. - Baylor College of Medicine - Fungi in Health & Disease

January 25, 2019
This week we welcome Professor of Pathology & Immunology and Medicine, David B. Corry, MD of Baylor College of Medicine, Michael E. Debakey VA Medical Center. We are looking forward to a fascinating discussion on Fungi in Health and Disease with Dr. Corry. 
Dr. Corry is a pulmonologist by clinical background and still practices, mostly focusing on allergic airway diseases such as asthma and sinusitis. Most of the time, he is an immunologist and his research focus is into the mechanisms underlying inflammatory lung and other diseases including smoking-related emphysema, asthma, and sinusitis.


Among his groups contributions to science, they have shown how fungi cause allergic inflammation-largely through their release of powerful proteases.  They have further demonstrated the ability of fungi to infect the mouse airway and produce a disease that is essentially identical to asthma and further demonstrated that common human disorders such as asthma and chronic sinusitis are often times, in essence chronic fungal infections. His group primarily relies on antifungal medications to treat their asthma and sinusitis patients. It has been revolutionary and they have published some of their experience, with more to come.

Dr. Corry also recently published a paper on Candida and how it goes directly from the blood stream to the brain in mice. We will also talk about non respiratory health issues and fungi including the state of evidence on Alzheimers, Chronic Fatigue and other health issues sometimes blamed on Fungi. If you are interested in Fungi and Health don't miss this show.

FLASHBACK FRIDAY - William (Bill) Vaughan, PhD Mold Assessment Issues and Answers | Original Air Date: 4-15-16 - Episode 410

December 7, 2018
Radio Joe and the team of IAQ Training Institute instructors are in Greenville, SC teaching all week so this week we will flash back to a great show we did with Dr. William (Bill) Vaughan about methods for assessing mold contamination and best practices for preparing for clearance air sampling. Over the years Dr. Vaughan has perfected a method for assessing Condition 2 areas in buildings and a method (air polishing) for cleaning the air prior to post remediation verification. He has had great success using and teaching these methods. We look forward to talking in detail today at noon.
Dr. William (Bill) Vaughan is President & Principal Scientist for Nauset Environmental Services, Inc. on Cape Cod Massachusetts. He has worked in the area of air quality investigations since the late '60s with a focus on IAQ issues for the last 15-20 years. He and his staff have carried out investigations at more than 3,000 locations in New England. Dr. Vaughan became interested in the IICRC's concept of Condition 2, settled spore, contamination just after the IICRC S520 was initially released in 2003. He asked the question, "If you can't see settled spores and colony fragments, how do you know if they are there much less if they have been cleaned up adequately? His group developed the concept of paired air sampling - quiet and fan-disturbed - to address this question and have been utilizing it productively since 2004. Dr. Vaughan's PhD is in Biophysics from the University of Illinois, Department of Physiology and Biophysics.
