Sealed Crawl Spaces with Integrated Whole-House Ventilation in a Cold Climate
- National Renewable Energy Lab. (NREL), Golden, CO (United States)
One method of code-compliance for crawlspaces is to seal and insulate the crawlspace, rather than venting to the outdoors. However, codes require mechanical ventilation; either via conditioned supply air from the HVAC system, or a continuous exhaust ventilation strategy. As the CARB's building partner, Ithaca Neighborhood Housing Services, intended to use the unvented crawlspace in a recent
