## Resource

Matt Risinger sits down with Bill Graber and Steve Rogers of The Energy Conservatory to explore how diagnostic testing informs high-performance construction. The conversation centers on blower door testing, pressure mapping, and airflow measurement as tools to verify airtightness and identify leakage pathways. They discuss how builders and energy raters use data to refine building enclosures, improve indoor air quality, and coordinate HVAC system performance. The group also touches on evolving codes, training, and the growing expectation for measurable results in residential construction.
