THERMAL BRIDGING IS LEAST OF THE ISSUES HERE!!!! 
This is the most dangerous framing I have ever seen. Allison you need to turn this construction in before someone is killed. Not being able to see this in the image you posted really makes me doubt your credibility in any construction advise. Hope you were wearing a hard hat when taking the image. I could not image imagine what the rest of the structure looks like.

This is crap, i have ever seen as architecture like this.

In Louisiana we build the chicken coop better than this, but not like energy efficient is a necessity but at least save $$$ on the structure!

All very good points and not necessarily easy to solve. I found that the easiest way to eliminate all of them is to build with double wall construction with insulation between the plates/headers/etc. I also have a similar method to deal with the sloped ceiling shown in the example.

Sorry but forget the thermal bridging, that thing is so far out of code compliance it isn’t even funny. If they can’t get the basics right, they are the last ones I would mention single top plates to for fear of being involved in a game of pick-up sticks when someone walked in.

Great article describing a way-too prevalent problem. Also, a great headline that made me want to read the article even though I guessed (correctly) what it was going to be about.

Yes, this is the problem with stick frame construction – even if done very well you are looking at 25-27% of building envelope (according to US DOE) to be stick frame. When you add in another 20-25% for windows & doors you are at 50% of the home that has an R value of about 4 or 5 no matter what kind of insulation is installed between the studs. Coupled with all of the air leaks that wood framing inherently provides, it’s a wonder this dinosaur still lives. People sweat buckets figuring out how to pay for the kitchen cabinets, and hence they build their homes out of the cheapest methods allowed by law….. 
 
Not that I have an opinion on this or anything…. 🙂

Someone should have informed that framer that rafter bird’s mouths typically go on the exterior side of the top plate, not the interior side (if they even did that…going by the gap between the doubled rafters…maybe not). As it is, the entire way this was framed at the featured location in the article appears structurally weak, aside from the thermal bridging concerns raised. There just does not seem to be much beef up there between the top plate and the roof deck.  
 
By the looks of things, when the drywall goes in, it will need to be sloped over the window to accommodate this odd framing technique. And that would raise another thermal boundary weakness…how to ensure adequate insulation gets into the cavity over that slope, and that any provided ventilation from the sofft does not wind-wash or even blow the insulation out?
