Methods of Provision
Teaching Methods The teacher holds lessons on theoretical topics which are constantly followed by calculation exercises that allow the student to continually self-check his learning process. During the lessons and exercises the student is encouraged to participate directly through questions and requests for further information on the topics covered.
Evaluation methods Verification of learning:
The exam grade is expressed in 30/30. The course offers the optional possibility to do four intermediate partial test, that allow to have a partial or total exemption of the final oral exam. The final oral exam consists of applied exercises from which theoretical questions are formulated on the course arguments.
Contacts/More Information The course is borrowed with the courses of "Applied Thermodinamics and Heat Transfer" and “Acoustic and Lighting” of the degree in Building Engineering L23.
