Demonstration of the syllabus coherence with the UC intended learning outcomes

The content covers all subjects related to the energy simulation needs of buildings, providing the knowledge so that the students have the necessary skills to develop works of energy simulation of buildings.

Teaching methodologies

Expositive and participative with predominance of practical applications.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

Final score equal or greater than 10 values.
Obligation to develop, present and discuss practical work.
The students will develop the practical work from the beginning of the UC, in which they will immediately apply the knowledge they acquire.

Assessment methodologies and evidences

Component A: Two tests (continuous evaluation)
Component B: Laboratories (practical work).
Component C: Written and / or Oral Exam.
Calculation of final score= 50% (Component A or C component) + 50% (Component B).
Comments:
1.Minimum score in each test: 8 values;
2. Minimum, average of the two tests: 9.5 values;
3. Minimum exam score: 9.5 marks.
4.Practical work is mandatory and eliminatory.
5. If Final scoreis equal to or higher than 18 points, the student should defend the score with an oral one.
