Title: Technology Solutions Case Study: Sealed Crawl Space with Integrated Whole-House Ventilation in a Cold Climate

The Building America team Consortium for Advanced Residential Buildings (CARB) investigated a hybrid ventilation method that included the exhaust air from the crawl space as part of an ASHRAE 62.2-compliant whole-house ventilation strategy. The CARB team evaluated this hybrid ventilation method through long-term field monitoring of temperature, humidity, and pressure conditions within the crawl spaces of two homes (one occupied and one unoccupied) in New York state.
