  1. We have posted the first episode of indoor air quality television, the web based televsion show related to indoor air quality, mold, building science and other issues. Episode 1 is all about air sampling with a trip to the lab to see video from the microscope lens while analyzing a spore trap. We hope you enjoy this and pelase leave feedback on what you think and what topics you would like to see in future episodes. The show can be accessed at: http://iaqforum.net/showthread.php?t=397 Episode 2 has been filmed and will be posted in about 1 week. This is a show report from the Florida Intercounty IAQ Council conference and expo in Ft. Myers Florida Arpil 19 and 20. We hope you will join us for that show too. Thanks. Jeff Deuitch Microbiologist Host, Indoor Air Quality Television
  2. Dread for the prices of these devices for sure. However, their function is thing of beauty once their limitations are understood. I once had a IAQ inspection in an immaculate condo unit. I observed a small (dime sized) round thermal anomoly on the ceiling. IR reflections were ruled out by viewing from many different angles. No staining of any kind was visible to the eye. Upon accessing the attic and focusing on the area where the anomoly occurred, it was discovered that water was dripping off of the A/C refrigerant line and was just starting to make it through the insulation onto the ceiling drywall. If not for IR, this would have gone unnoticed completely. I am not a HI but an environmental scientist. Nor was I even paid to do a detailed inspection, only a visible mold inspection and air sampling. However, IR resulted in helping the client avert a very significant problem that was just beginnning. Since this was an unoccupied unit, it may have been weeks or months before someone would discover a very big problem and an angry phone call to me. While I used to sell IR as a separate service, it is now part of every inspection. Not a luxury, but insurance against hazards to me of the legal variety. AS for routine HI, time will tell if this becomes standard. If the competition has it, others may lose business as a result. Hopefully prices will come down to real world levels by then. I hope to get representatives from thermal IR manufacturers to interview on our upcomming Internet TV show "IAQ Television" our first episode should be done in a week to ten days. Check back to The IAQ Forum for updates if you are interested. Regards. Jeff Deuitch Microbiologist Administrator, The IAQ Forum www.iaqforum.net
  3. Thanks for the warm reception. The house is actually most CB with frame utilized on the bay shaped area. The B&W image is a window in the CB area. My main concern is that if air infiltration is occurring, then in the summer months with very high water vapor levels could this be a significant condensation risk? If you saw the visible images in second post, then you see how there is cracking and deformity in the small trim piece in the baseboard trim. In February, water vapor levels in SW Florida are not that high and dew point levels are quite low. While not quite visible in the more distant photos, the deformity and cracking was quite evident in many locations along the baseboard. Thanks.

  4. And that's why I dread the onslaught of IR cameras in the home inspection profession. Well, the dark areas are cold. It seems to me that the cold spots have to be from one of three things: water, cold air or a shadow that prevents those areas from getting warm. If you've ruled out water, the next most likely thing is cold air -- I'd look for missing or spotty insulation. But what the hell do I know? I'm not a thermographer. It's interesting how the black & white picture clearly shows the studs but the color pictures don't. Why is that? - Jim Katen, Oregon Black and white shows more detail. Color shows more contrast. I use both. The camera I use( a FLIR B-2) has numerous color palettes which have different strengths and weaknesses. The effect you refer to probably has more to due with the subject being photographed. Also, when lower temperature range is selected, greater contrast will be seen in either B&W or color.
  5. I recently performed an IAQ inspection of a house with a site the sloped upward away from the structure thus promoting flow of rain water toward the structure. I used thermal infrared imaging to view in the interior side of the exterior wall. Several thermal anomalies were discovered along this wall is a wide range of locations. However, none of the areas with anomalies showed elevated moisture when tested with a Protimeter MMS moisture measurement meter in either destructive or non-destructive modes. Can anyone suggest what conditions in the structure may have lead to the observed anomalies? The house is about 50 years old but very well renovated. Could this be due to cold air infiltration? The anomalies are not regular in shape or distribution. The photos and brief description can be found at: http://www.iaqforum.net/showthread.php?p=227#post227 Thanks. Jeff Deuitch Palmetto, FL
  6. To assist those with concerns related to mold and indoor air quality issues, we have created a new mold, moisture intrusion, and indoor air quality forum. Individual forums within the site pertain to the general public as well as affected professionals including real estate and construction personnel, insurance industry members, architects, investors, home inspectors, and others. Visitors can ask questions, commence discussions related to IAQ and mold related topics or provide guidance to other needing help. There is even an "ask the microbiologist" section where concerned parties can post technical questions related to biological issues to a microbiologist experienced in building investigations and biological research The site can be visited at: www.iaqforum.net We hope this site is informative and helpful and hope you will visit us often. Thanks. Jeff Deuitch Microbiologist Administrator, The IAQ Forum
