Public Review of Fully Revised CCAH

Reducing Radon Soil Gas Control in New Construction of One & Two Family Dwellings and Townhouses


Consistent with ANSI requirements for harmonization of standards where possible, the proposed revisions to CCAH are holistic relative to more recent work on ANSI/AARST CC-1000. 

The scope is broadened to include both radon and other soil gas hazards. 
The format is step-by-step through design and implementation.

These steps and details vastly increase the chances of passive benefits while optimizing energy conservation when operating fans where active soil depressurization (ASD) is desired or found needed.
