SUMMARY:Crawlspace Retrofits in Electrification Projects: Health Benefits\, Moisture Management\, and Wildfire Safety
DESCRIPTION:Part 2 of 2  \nMany existing crawlspaces require remediation prior to other energy upgrade work\, including attic or electrification upgrades. This course examines retrofits of vented and unvented crawlspaces\, tradeoffs between each crawlspace assembly\, and the crawlspace assembly’s impact on the home’s overall performance and comfort. From home durability to occupant safety and comfort\, Dan Perunko of Balance Point Home Performance will address moisture and vapor sources\, rodent control\, as well as strategies to reduce wildfire ember intrusion. \nAgenda: \n\nIntroduction and safety message\nUnderstanding the phases of water and how it is transported\nPrioritizing and mitigating sources of moisture\nRemoving accumulated debris and abandoned systems\nReviewing current common practices\nDecision to vent or not to vent and evaluate all the existing conditions\nUpdating existing foundation vent to reduce wildfire ember intrusion\nAddressing weather proofing on existing foundation vents\nReduced foundation venting\nConverting a vented crawlspace to a sealed crawlspace\nAddressing abandoned foundation vent holes\nAir leakage control implications\nRecladding the skirt to achieve multiple outcomes\nTesting the assembly\n\nThe objective of this course is that at the conclusion\, participants will be able to: \n\nPrioritize source control of moisture in crawlspaces\nDefine how water in liquid or vapor form is transported\nName performance tests that can be used to evaluate the moisture balance of the crawlspace\nExplain performance problems associated with typical foundation vents\nDescribe ways to improve wildfire resistance by updating the foundation vent strategy\nList an example of a crawl space type that is not well suited for converting to a sealed crawlspace\nDiscuss methods for addressing abandoned foundation vents\nExplain the difference between a vapor barrier and an air barrier\nState why a consumer might choose to upgrade from a basic unsealed plastic layer in the crawlspace\nIdentify ways to test the performance of a plastic layer that is serving as an air barrier in the crawlspace\nSummarize the real world benefits of installs of ground cover to meet different performance outcomes
