Whoops! Too Hot!

This is upper west part of ARC08 South wall. See the wet looking spots on the glazing panels near the right?

I was wondering why those panels looked wet all the time.

Then I noticed that, inside the house, that portion of the wall seemed colder than the other wall at night and warmer during a sunny day. Curiosity got the best of us. Friday we drilled a 3 inch whole through the sheetrock and found that all the styrene foam in the sip was melted away and the resulting cavity was 225 degrees F.
