Insulation in a REMOTE wall cavity?
I am very interested in the PERSIST design but all i can seem to find when i search for details is REMOTE. I just saw a REMOTE wall detail in a jlc forum that included 2 x 4 wall framing and then fiberglass insulation in the cavity. Isn’t that going to lower the temp of your sheathing? kind of defeating the purpose of this type of construction? Also, I recently read a 2010 article by the CCHRC about a study done in 2002 in Alaska, and they found that the REMOTE style home they tested burned twice as much fuel as they had predicted. Would this be a result of not using the membrane on the roof? or is it possible that an oversized boiler, as they suggested, could be the reason? thanks in advance

Chris,
I assume you saw my article on the topic: Getting Insulation Out of Your Walls and Ceilings.
Another resource is this Home Energy article by Chris Makepeace: "Wrap It Up: Building Houses with the Skin on the Outside."
I agree with you that it's best to omit any insulation between the studs of a PERSIST wall. If you do end up putting insulation in the stud bays, be sure to do a dew-point analysis to be sure your sheathing won't get too cold.
