Main Aims/Objectives

In this curricular unit, particular emphasis will be given to the thermal performance of buildings, which will be evaluated and will be subject to minimum energy efficiency requirements, with a view to promoting the improvement of their thermal behavior, the prevention of pathologies and environmental comfort, focusing on the characteristics of the building. opaque and glazed surroundings, and energy efficiency requirements for the main types of technical systems.

Specific Aims/Objectives

It is intended that students are able to understand the conceptual and constructive technical requirements to obtain improvement in the energy performance of buildings.

Skills to be acquired

Obtain knowledge to be able to define the compositions of building systems, knowing how different building systems work, namely those related to the energy performance of residential buildings (REH), in order to ensure and promote the improvement of the energy performance of buildings that students will be studying, through the building energy certification system (SCE).

Teaching Procedures

This curricular unit has a weekly schooling of four hours, two hours of formal theoretical exposition, and the other two are dedicated to solving exercises and carrying out practical work, which will be integrated in continuous assessment, which will consist of the individual application of the Energy Performance Regulation of Housing Buildings (REH), in an autonomous fraction of a project carried out by the student in another course subject.

Evaluation Type

Students perform evolutionary work on the material taught in class. Continuous assessment includes attendance to classes, student performance in carrying out the proposed exercises, delivery and evaluation of the work developed throughout the semester, all complemented with two written tests, of theoretical / practical nature, in the case of classes already can be carried out in person.

Teaching Resources

The theoretical introduction of the material is carried out with the visualization of elements that are available to students on the moodle platform. After the theoretical introduction, exercises related to the subject follow, with the statements of these same exercises also available to students on the moodle platform.
