Please Click the Image Above to View the DOE's Report

Please be advised that we have highlighted pertinent sections of the Department of Energy's report and added notes on how Coastal Dry Home's Humidex CCC-103 Crawl Space solution  provides the preferred and code-compliant means of conditioning an unvented/sealed crawl space.  Click here to view an unmarked version of the report on the DOE's website.  

For additional documentation supporting the compliance and effectiveness of Coastal Dry Home's Humidex CCC-103 solution please check out the Environmental Protection Agency's Technical Guide for Moisture Control and the International Residential Code as they apply to the conditioning of unvented/sealed  crawl spaces.

(Note that the Department of Energy, Environmental Protection Agency and International Residential Code do NOT mention dehumidifiers as an approved/compliant means of conditioning crawl spaces.)
