Free MIT course materials: Introduction to Building Technology
I was looking for something else, and came across this course fro MIT, apparently free, called, "Introduction to Building Technology".
I came upon it while searching for some graphics, and was struck by the quality of the images, which led me back to HERE.
It looks like on-line materials about the course, but could be useful
But free info from MIT, such a deal!
Looking through it, there don't seem to be any lecture files, but there is enough other material that it could still be useful.
I'm not an HVAC technician. In fact, I'm barely even a hacker...

I just glanced through the course notes, specifically chapter 7, moisture control. And they have a whopper there. It shows that a vapor retarder should be on the warm side of the walls. That's just wrong.
I agree with SF on this. Who wants to be wrapped in plastic. All moisture is retained within the enclosure then, kind of like being in a wetsuit. Yuck. Bad info is just being handed down from generation to generation on this subject and when someone points it out all you hear is crickets chirping. Why doesn't anyone question these unexamined assumptions?
Here's a good article that talks about all the myths about the required use of vapor retarder and also the very few times and places they are needed:
