APPLIED PHYSICS FOR ARCHITECTURE
Learning outcomes of the course unit
At the end of the course, the student is expected to be able to:
- learn the fundamental principles of thermodynamics and their technical implications.
- learn and know how to apply the fundamental heat transmission mechanisms;
- learn and know how to apply mass and energy balance;
- be able to calculate the amount of heat and mass exchange between the building and thermotechnical plants, as well as between the building and the surrounding environment.

The course is divided into lectures and tutorials, which are an opportunity to assess and clarify the theoretical knowledge acquired.
Assessment methods and criteria
The exam consists of a written test (60 minutes long) containing two numerical exercises (with a value of 7 points each) and two theoretical questions (with a value of 7 points each).
The results of the written test will be sent by email to the students. Those who have passed the written test (it means having obtained at least 18 points) can take an optional oral examination ( +/ - 5 points).
On "Elly" website, you can find manyexamples of the past exams.
