- Synopsis:
-
Detailed information for future building physics specialists in the field of thermal and moisture behaviour of structures and buildings. Methods of preparing input data for calculations, transient models of thermal and moisture behaviour of structures, use of simulation models of structures in practice, multidimensional heat transfer and its use for more accurate determination of properties of structures (thermal transmittance of curtain walls and windows, linear thermal transmittance of point facade anchors, etc.). Fundamentals of CFD modelling (heat transfer by conduction, radiation and convection in building structures and buildings).
