Insulation is installed on all exterior walls, creating a "sealed" shell. While not directly conditioned space, the attic stays very comfortable. The energy efficiency ramifications are huge, but steps must be taken to ensure the house is sufficiently ventilated.
I believe they refer to it as "build it tight and ventilate it right"
I'm seeing spray foam a lot more here in the bay area. It can be 100 degrees outside but the attic is I'm guessing mid 80s.
And to the OP - wire in closets, mud room, pantry to get the coverage and put whatever AP is required. The AP will change at some point due to obsolescence upgrade.
