Abstract70% of all construction problems are related to moisture. This course aims at providing the necessary theoretical background in order to foresee and avoid these problems.
Objective• to develop a basic understanding of mass transport and buffering
• to become aware of potential moisture-related damage and health risks
• to learn how to (i) design building components and (ii) assess their hygrothermal performance
Content• hygrothermal loads
• conservation of mass
• dry air: constitutive behaviour, transport, potential problems and solutions
• moist air: constitutive behaviour, transport, potential problems and solutions
• liquid water: constitutive behaviour, transport, potential problems and solutions
• moisture-induced degradation processes
• case studies
• exercises
Lecture notesHandouts, supporting material and exercises are provided online (http://www.carmeliet.arch.ethz.ch/Education/ with Building Physics II: Moisture in the Documents section). The course syllabus can be bought at the Chair of Building Physics.
