In the pursuit lifelong learning, Alex and Jason of the Infrared Training Center (ITC) paid a visit to a local elementary school looking to recruit the next generation of thermographers. What originally began as a single class demonstration (roughly 25 kids) blossomed into a gathering of the entire fifth grade class, over 90 children!
During a brief hour long presentation, the students were exposed to a crash course on infrared application and technology. The session sought to answer three basic questions: what is infrared, why do we use it, and how does it work?
The enthusiasm displayed by the students was both refreshing and uplifting. Not only could we see the energy we could feel it as well! The kids were shown hands on demonstrations which made learning about conduction, convection, and radiation heat transfer both fun and exciting.
The radiant culture of infrared (no pun intended) left a lasting impression on the children as well as the faculty. The session concluded with a quick photo opp. and an extended invitation to make an annual presentation for the students.

Building conversations in training this week brought up the subject of thermal bridging in the structure. Defined by a material of less insulation or greater conductivity. This material bridges or short circuits the better insulation and reduces its effectiveness. This reduces the overall R value rating of the whole assembly. The following website, http://web.ornl.gov/sci/roofs+walls/AWT/home.htm , addresses this whole wall rating concept. This isn’t a debate of test methods or approaches. It is enough to say that anything put in the wall that reduces the energy of that wall should be addressed in the construction process.
My input on this subject is finding these, before construction begins and discussion with a builder, methods to reduce or eliminate these bridges. Verification of the design or confirmation as building progresses would be where a thermographer can enter the process and provide proof that the building project has conformed to this concept of design.
The images from a qualified thermographer provide detailed analysis of construction detail typically hidden from the inspectors or builders.
Taking a set of images to compare this approach can clearly see the advantage of reducing the vertical framing typical of stick built construction. Even the wide wall of 2x6 framing to increase the side wall dimensions for increased insulation. This is an increase in the R value but the thermal bypass of the stud is still there.
Using SIP to reduce bridging
Standard stick frame wall
Looking at a SIP wall can visualize the reduction in the bypasses by reducing the vertical framing. The corners and joints are still present but can be reduced by the same methods of stick built using exterior insulated sheathing.
Making the bridge elimination or reduction a conscious thought in the whole building process can have substantial rewards in energy saving in the home.

Can’t make any of the scheduled broadcast dates? Not to worry, all live sessions are recorded for playback at any time. These on-demand presentations are also listed on the main webinar page and are accessed with a simple (and free) registration.
September 9th to September 12th, 2015, San Luis Obispo, California
This course is RACE approved for 26 CE hours and is endorsed by the American Academy of Thermology. Designed to teach Veterinarians all aspects of Thermal Imaging through lectures, case-based problem-solving & practical experience, this course is presented by Internationally recognized Thermographers:
Dr. Tracy Turner
Dr. Kimberly Henneman
Dr. Ken Marcella
The workshop consists of all species related lectures and interactive wet labs. The course focuses on clinical thermal imaging as it is incorporated in a multi-modality approach to achieving diagnosis.
Participation will provide attendees with a functional understanding of the use and application of thermal imaging in all aspects of clinical veterinary practice.
It can take being uncomfortable for some homeowners to really start thinking about the efficiency of their house. Certainly, the bill from the electric company or that propane truck *once again* backing into the driveway all serve as painful reminders that your home uses (too much) energy. However, when air leakage across the floor leaves you with cold feet, or you find yourself always shivering from a draft on a windy day, it starts to get old...fast. Experiences like this can help motivate one to consider putting energy efficiency improvements on the fast track.
This assumes, of course, that the occupants are *feeling* cold in the first place. How about when it might not be as obvious, such as the case here? Sometimes thermal imaging can help a homeowner understand why what they are experiencing (feeling) is very different from what is actually happening.
These infrared images (above) were taken near the rim joist in the basement of a contemporary-style home built in 1984. The residence has wood floors, fiberglass insulation and, not surprisingly, a decent amount of air leakage (3550 CFM 50).
As expected, one of the larger areas of air infiltration in the structure is located around the rim joist. What you will notice too is that the home also has a radiant floor heating system (images below):

They are several types of steam valves:
Safety Relief Valves
How you inspect them is different, but first, a little bit about steam. When you boil water at atmosphere it will reach 212˚F (100˚C). Put it in a pressure vessel and continue heating, adding another 960 or so BTU’s and it becomes steam, but still at 212˚F (100˚C). Pretty useless, though. Keep heating it and the pressure goes up. That heat is called enthalpy. That’s the energy steam turbine blades extract via pressure drop to make power and it’s an important concept in steam valve leakage diagnosis.
Steam is hot and many valves and lines are insulated. This is a problem for inspection. I used to have holes in insulation cut anywhere from 10 to 16 “pipe diameters” away from the valve, on the bottom of the pipe and use high temp black paint. I would also cut a hole in a convenient location upstream of the valve and within a day of startup establish a baseline.

As promised, here’s the link to download the free White Paper from today’s live webcast “Best of InfraMation: How to Guarantee Your Failure as an Infrared Thermographer”. We’ll also be posting this session soon as an on-demand recording.
The value of thermal imaging for use in predictive maintenance has been demonstrated and well-documented for decades. Practitioners in the trade, however, still generally fall into two categories – heroes or goats. Originally presented by ITC instructor Ron Lucier at the 2002 InfraMation conference, this free white paper highlights ten common activities that, if not properly addressed, would lead a thermographer down the path to failure. Read about what those ten activities are and see how this perspective still applies today.
The InfraMation conference, the world’s leading IR training experience, is pleased to announce that Brent Bushnell, CEO of Two Bit Circus, a Los Angeles-based experiential entertainment company and Terrance O’Hanlon, CMRP and Publisher of Reliabilityweb.com®, RELIABILITY® Magazine and Uptime® Magazine, will be leading Keynote Presentations at this year’s event in Nashville, Tennessee May 11-14, 2015.
Brent Bushnell and the team at Two Bit Circus recently launched STEAM Carnival, a modern re-imagining of the midway to inspire kids about science, technology, engineering, art and math. Previously, Brent was the on-camera inventor for the ABC TV show Extreme Makeover: Home Edition and was a founding member of Syyn Labs, a creative collective combining art and engineering for large brands including Google & Disney. In his spare time, Brent mentors teens in game development and entrepreneurship via programs such as Spark and the Network for Teaching Entrepreneurship.
Terrence O'Hanlon, is also the acting Executive Director of the Association for Maintenance Professionals and the Executive Editor and Publisher of the 5th Edition of the Asset Management Handbook. A voting member of the US TAG (PC251) for ISO 55000 - ASTM E53 Asset Management Standards Committee, Mr. O'Hanlon more recently was selected as the sole US Representation through ANSI for ISO Working Group 39 to create a standard for competence in assessing and certifying Asset Management programs known as ISO 17021-5.
