From The Build Show.

Join energy consultant expert Randy Williams and Build Show team member Mark Wille as they decode airtight building enclosure strategies, codes, measurements and risks. Learn about key air change metrics and their importance in meeting code requirements and optional certifications like PHIUS. Explore how these metrics compare to natural air change rates and learn about the risks of overly tight structures including pressurization, appliance back-drafting and indoor air quality concerns.
