In this episode, I interview Villy Yordanov, a mechanical engineer and innovation engineer at Pro Clima. We discuss the importance of building science, sustainability, and moisture management in construction. Villy shares his journey into the field, the role of WUFI in hygrothermal modeling, and the significant challenges associated with managing moisture in concrete structures. The conversation also addresses common misconceptions about moisture in buildings, the balance between air tightness and vapour control, and the latest innovations in building science.
