This permitted installation of straw/clay wall insulation had to meet Washington energy code and International Building Code standards. Existing code supplements from other states were referenced and applied by the building team and the approving building department. The straw/clay insulation filled a 12” thick split stud cavity in a single family structure at the Port Townsend Ecovillage. It appears that this was the first straw/clay house permitted in the State of Washington. The permit was issued in May of 2013
