This week Shelly Miller, PhD joins us to discuss some recent research and thoughts on weatherization, ventilation & respiration. We hear a lot that we need to tighten homes and ventilate them. What does that do with respect to occupant health? Today we will go over some results from work Dr. Miller has done.
Dr. Miller is an Associate Professor at the University of Colorado Boulder in the Mechanical Engineering Department and faculty in the interdisciplinary undergraduate Environmental Engineering Program. At the University of Colorado Boulder Dr. Miller investigates indoor air quality, assesses exposures to air pollutants, and develops and evaluates air pollution control measures. Her research has included studying weatherization of homes and indoor air quality, understanding the role of ventilation systems in the transmission of infectious agents in buildings, engineering controls for reducing exposures to infectious diseases, studying ultraviolet germicidal coil cleaning technology, source apportionment of particulate matter and associated health effects, characterization of indoor air quality and the microbial communities in homes, and investigating urban air quality issues including industrial odor episodes. Dr. Miller has received funding for her research program from the US EPA, CDC, NIOSH, NSF, NIH, ASHRAE, HUD, Alfred P. Sloan Foundation, and various private foundations and industry sponsors.

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.

This week on Iaqradio+ we flashback to a great show with Lew Harriman and Terry Brennan from 7-11-24. The EPA Moisture Control Guide is one of the best, if not the best document EPA has developed in 20 years. Terry Brennan and Lew Harriman join us to discuss the document and give us their thoughts on evaluating moisture issues in buildings. If you do not have this document in your library, get it, its free and your tax dollars helped to put it together.
Terry Brennan was the lead author for the EPA's new Guidance for Moisture Control in Buildings. He is a founder and managing partner of Camroden Associates, a building science consulting firm located in Westmoreland, New York. He began his career as a physics major at Northeastern University, but some how, some way got diverted into building science, working on the earliest research into radon problems and radon behavior in buildings, and moving on to energy and moisture issues. For the last 40 years, he's spent more time crawling around damp basements and hot attics than most normal people would find pleasant. But in return for those decades of investigation, Terry knows a LOT about what makes buildings tick... how they go wrong... and how to make sure they don't.
Lew Harriman was a contributor to the new EPA guidance for Moisture Control in Buildings on the HVAC aspects of moisture control. He began his career as an architecture student at Dartmouth, but after five years as an Air Force officer, he went to work for a manufacturer of dehumidification systems, and got permanently diverted into HVAC engineering, where he's spent the last 38 years. He is the founder of Mason-Grant Consulting, a building science consulting firm located in Portsmouth, NH. He is active in ASHRAE as the vice-chair of technical committee 1.12 (Moisture Management in Buildings), and is an ASHRAE Fellow and Distinguished Lecturer.
