![]() ![]() In homes with crawl spaces, 40% of your fresh air comes from this unwanted source. In California, the average duct leakage is 30%, which for many forced air systems amounts to 600 to 1000cfm (cubic feet per minute) of air being pumped out of the building envelope, causing a home to draw in toxins from these unwanted sources. What has become clear to me over the past year is that many mold remediators are focusing on cleaning techniques and missing the building science factors that draw air into the living space from unwanted sources: the attic and crawlspace. The Healthy Home Clinic presentation includes a few slides on mold issues and toxin infiltration from the crawlspace due to duct leakage and depressurization. ![]() Most homes have significant indoor air quality issues, and if several factors conspire to create the perfect storm, a home can be very unhealthful, especially if you are one of the 24% of the population with a genetic predisposition to a severe chronic inflammatory response (CIRS). The statistics are something to be concerned about. The building science principles illustrated in these slides focuses on how air moves through a house and where the air you breathe is coming from. The Healthy Home Clinic is a free educational seminar that is held in San Luis Obispo California on a monthly basis to educate the public about indoor air quality problems, many of which are cured when energy efficiency problems are addressed - and there is a significant return on investment in terms of energy savings as well as grants that are available in many states from public utility agencies. 500 State of the Art Answers to Mold QuesstionsĬlick Here to Download the 2013 Healthy Home Clinic Presentation as a PDF.Surviving And Thriving A Recovery Manual for Patients and Families Impacted by CIRS. ![]()
