I'll be selling the books at RESNET, ACI, B4, and HVAC Excellence, if you want one in person instead, Paul!

Comment by Paul Lasicki on February 14, 2012 at 9:31am

Thanks Corbett,

Is there a way to order the book without signing up to LULU ?


Comment by Corbett Lunsford on February 14, 2012 at 9:15am

Paul- there's a new resource that spells out all those tests with step-by-step photos!  It's called Home Performance Diagnostics: the Guide to Advanced Testing, and it's available by clicking here.

Also, here's a page from the DOE weatherization curriculum with locations for CO sampling for many draft types.CO%20PROBE%20LOCATIONS.pdf

Comment by Paul Lasicki on February 14, 2012 at 3:56am

Hi, first, thanks for having created this group.

I would like to see BPI come out a complete section on testing for spillage, co, draft and efficiency on all the different Heating and DHW venting/ power venting, induced fan, direct venting, sealed combustion, etc.configurations out there, along with the difference between negative and positive venting.

Comment by Leslie McDowell, BPI on October 28, 2011 at 5:31pm

Hi Timothy, That's great news! If you can stand it, my main advice would be what your mother would say: eat all your vegetables, go to bed on time the night before, arrive with a clear head and a sharpened #2 pencil. Take good notes.

Beyond that, I recommend researching the "house as a system" concept of whole house energy efficiency. Start with this video, and read this page of our BPI website. You may want to look over the BPI Building Analyst Field Guide. If it is confusing, don't worry. It will make sense to you after you take the course. If you're really ambitious, Google the term "Whole House as a System" and browse; there's lots of interesting material out there. Best of luck!

Starting BPI Analyst on Monday. Any tips would be greatly appreciated. Thanks.
Comment by Leslie McDowell, BPI on September 14, 2011 at 6:41am

Thanks for the question Sean. BPI can provide only a very general response, given the lack of specifics concerning the question.


If a contractor is stating an R value of 20, they would be required to verify the success of the installed measure just as they would any other measure. There will be a certain degree of variances (installed specifications) between R ratings based on the actual insulating materials being used. 


To achieve an overall insulation rating of R 20, the ducts would typically require extensive insulation being applied directly to them. While this may not be impossible, it may be highly unlikely given the fact that heating/air conditioning ducts frequently run in confined spaces, such as wall and ceiling bays. Ducts located in any confined spaces would allow only a certain amount of insulation to be applied properly.

Comment by Paul Raymer on September 13, 2011 at 2:19pm
Sean - You could use Rick Karg's Zip TestPro software to calculate the R value by knowing the delta T between the indoor surface temperature (the temperature of the wall of the duct) and the ground temperature around the duct and the temperature of the air in the duct and the temperature of the wall of the duct.  The software will then provide you with an R value.  (
