Building Science Videos

Guide to Home Performance 

This series of videos was sponsored by the California Energy Commission as part of the Measured Home Performance Project that develops guides to best practices for home energy retrofits in California. The videos, co-hosted by building science consultants Steve Easley and Rick Chitwood (CHERP Board of Advisors), explain the step-by-step process of retrofitting homes to save 50 - 80% of their annual utility bills, while dramatically increasing comfort and indoor air-quality- all accomplished before solar panels are installed!
