Jessica Kismet is a building designer, Certified Passivhaus Designer, and WUFI professional who specialises in building performance, enclosure diagnostics, and indoor environmental health. Driven by a philosophy that prioritises function and verifiable performance over form, Jessica’s expertise bridges the gap between complex building science theory and practical, on-site execution.

‍

Her background is rooted in strict code compliance and energy efficiency ratings, which naturally evolved into advanced building enclosure consulting. Jessica brings extensive field experience in air tightness strategy and has experience conducting rigorous blower door testing for both residential and commercial structures. As a WUFI professional, she utilises advanced hygrothermal modeling to analyze heat and moisture transfer through assemblies - allowing her to accurately diagnose the root causes of condensation and enclosure failures, or prevent them entirely during the design phase.

‍

In recent years, Jessica’s diagnostic focus has expanded deeply into the realms of building biology and mould forensics. She approaches buildings as holistic systems, understanding that structural performance and moisture management directly dictate indoor air quality (IAQ) and occupant health. Her comprehensive understanding of energy frameworks - from local codes to international Passivhaus standards - provides a robust, evidence-based foundation for her consulting work.

Beyond her field and diagnostic work, Jessica is a dedicated industry educator and a leading voice for better building practices. As the host of the Building Sociology podcast and a frequent speaker on sustainable construction, she is passionate about translating complex science into actionable strategies for the industry. At Building Science Advisors, her multidisciplinary background in design, forensic testing, and moisture management ensures that clients receive independent, technically rigorous guidance to resolve failures and verify performance outcomes.
