Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

Provide the Masters in Electrotechnical Engineering with knowledge in the field of Rational Use of Electric Energy (UREE), motivated by growing social and business demands.At the end of the course, the student should be able to analyze electric energy (EE) invoices, allowing him to choose the best option for each situation, to plan, execute and interpret the results of an EE audit and make decisions that lead to a use more rational use of the EE.

5.4. The concept of least cost planning ("least-cost planning").
5.5. Cost-benefit analysis of demand-conditioning programs (DSM).

Demonstration of the syllabus coherence with the UC intended learning outcomes

Students are taught the principles of electricity tariffs. Along with opportunities for the rationalization of consumption that result from audits of electricity, students will be able to do analysis of return on investment for the different solutions that are presented. Information about the use of passive solar energy, allow students to use alternatives potentially leading to more economical solutions.

Teaching methodologies

The theoretical concepts are taught using the method expository dialogues. Theoretical concepts are applied in practical exercises, laboratory, and case studies/seminars.

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

In the classes are exposed theoretical concepts. Students are then asked to put into practice, in the face of some real situations, the theoretical concepts learned. The application of the principles will be performed through theoretical and practical exercises, laboratory and case studies /seminars.

Assessment methodologies and evidences

Work on analysis of energy consumption and tariff analysis (T1);
Work on analysis of the behavior in the consumption and billing of electric energy (T2);
Laboratory work on lighting technologies (T3);
Work with specification of a power management system for an installation (T4).

Final classification (Nf):
Nf = 0.25 * NT1 + 0.25 * NT2 + 0.15 * NT3 + 0.35 * NT4
