Teaching methods and learning activities

There are 2 theory classes a week, of the explanatory variety, with each class lasting around one hour. There is also one practical class a week, lasting 2 hours, where exercises are solved, assignments are done, and the matters addressed are discussed.
We seek to make sure the content of practical classes, whenever possible, is given in parallel with the theory classes.
During theory classes, overhead and PowerPoint are basically used as a kind of support for the exposition, which allows to better follow up on students and for them to visualize the content of the subject matter. Students have a class at the Building Physics Laboratory in order to come in contact with the equipment used for measuring temperature and humidity in construction materials and elements.
