The software user will model the crawl space as a separate unconditioned zone, selecting appropriate vented crawl space (with raised floor insulation), the perimeter of the crawl space (in linear feet) and the height of the crawl space.
Standard Design
The standard design has a typical vented crawl space when a crawl space is modeled in the proposed design. Otherwise, the raised floor is assumed to be over exterior or unconditioned space.
Verification and Reporting
The crawl space zone type and characteristics shall be reported on the CF1R.
