The envelope is where all performance is won or lost. This module covers building envelope fundamentals in plain language — how heat, air, and moisture move, and how to control all three. Topics include thermal bridging, air control, moisture management, drainage, penetrations, window performance, and verification through testing. Get the envelope right and the building stays comfortable, stays dry, and needs far less equipment to operate — no football field-sized solar array required. If the envelope is wrong, no mechanical system can fix it.
