Anotation:

The course is focused mainly on the practical numerical modelling of hygro-thermal processes in constructions and buildings. It is assumed that students already know the basic principles of building physics.

Students can learn how to calculate thermal transmittance and water vapor condensation risk in building constructions (including effects of thermal bridges). Basic and advanced calculation models are used during the course (Glaser, Wufi). Energy performance calculation is another theme of the course with focus on low-energy houses.
 

Goals:

Introduction to the basic procedures of hygro-thermal calculations.
