The part of the building academia overlooked — the space between surfaces.  Water Vapor Aloft™ is what happens when the enclosure performs as intended:

vapor remains suspended, latent energy is harvested, people feel well, and energy efficiency reaches its extreme.

I took the most basic AAMA metric — the Condensation Resistance Factor (CRF) — and built an entire new envelope science.
