Crawl spaces and basements are typically a source of unwanted heat loss, moisture, odors and polluted air. Conditioning them can solve some problems, but in low energy homes this strategy may incur a substantial energy penalty. Alternatively, isolating the crawl space can be more effective at reducing heat loss to the ground, but less effective at improving building durability. How do you determine the best strategy – isolating a crawl space or basement or bringing it within the home’s thermal and pressure boundary? Also, what materials and techniques are appropriate for insulating and air sealing a crawl space or basement, and where should they be located?
This 2-part technical webinar is the latest in a series designed to support deep energy reductions in existing homes, as demonstrated by ACI’s Thousand Home Challenge. It addresses the complex interactions of heat, air, and moisture flow, as well as migration of pests and soil gases from the ground through the foundation to the living space. It also takes into account the additional considerations of resistance and resilience to flooding, building and energy code requirements, and the presence of mechanical equipment and utilities.
Presenters Graham Irwin and Gavin Healy expand on their highly rated session “The 6th Side - House to Ground: Getting to Low Energy, Healthy Homes”, from ACI’s June 2012 regional conference in Sacramento CA. In both webinars, their presentations will be followed by a facilitated discussion with experts Don Fugler and Rick Cowperthwaite.

*The GoToWebinar Attendee Report will be the official record for awarding BPI CEUs. Credit is awarded only to fully credentialed BPI Certified Professionals. Attendees must be individually logged-into the Web Exchange to receive BPI CEUs. Credit will not be awarded for attendance by telephone alone. At the end of the Web Exchange, the Attendee Report is submitted to BPI by the webinar host, and BPI will award CEU’s based on the amount of time in session and interest rating. Credit is calculated using an arithmetic mean of the time in attendance and interest rating as compared to 100% attendance for the scheduled time and 100 Interest Rating. Attendees must be logged in for any portion of the credit to be awarded. Credit will not be awarded for later viewings. Credit is calculated and awarded by BPI and BPI’s determination is final.
