Most conversations about a building's carbon footprint stop at energy use, but the materials themselves carry a hidden cost. This post breaks down embodied carbon, the emissions locked in before a building is ever occupied, and looks at the peer-reviewed research showing how straw and other natural materials can turn construction from a carbon source into a carbon sink.

Building naturally in hot, humid coastal climates is entirely possible, but it demands careful attention to moisture detailing. This post breaks down why raised crawl spaces are often a liability, how a properly layered straw panel wall is built to dry rather than trap moisture, and what coastal wind and salt exposure mean for materials and fasteners.

Perm rating measures how easily water vapor moves through a building material, and it's the number that determines whether a wall assembly can dry out or traps moisture over time. Materials fall into four permeance classes, and because Columbia sits in a mixed-humid climate zone, high-performance natural building favors vapor-open assemblies that let walls dry naturally rather than sealing moisture in.
