Maximize the building's climate mitigation effectiveness by making it functional for generations.

Having to replace or rebuild portions of the enclosure adds significant embodied emissions over the building's lifetime. To ensure durability, we need to use reliable materials that are put together correctly, are repairable, and are protected from damage for the life of the building.

This can be accomplished by using materials that are lab tested for 100+ year durability, most importantly the adhesive connections that come under long-term stress. Materials like spray foam that will degrade do not belong in a high-performance enclosure. Protect the air, vapor and thermal control layers with a service cavity inboard, and a back-vented rainscreen outboard to prevent damage in the course of regular use and during future renovations.
