Learning outcomes
Type A Code Learning outcomes
 CE4 Model the thermal performance of buildings using specific software.
Calculate the annual thermal loads of buildings.
Determine the dimensions of the air-conditioning systems required by buildings to meet thermal demand
Carry out parametric analyses of the different variables in a building to study their effect on energy demand, costs and environmental performance.
Optimise building energy demand, costs and environmental performance of different building variables such as building geometry, orientation composition of the enclosure
Type B Code Learning outcomes
 CT3 Recognise the situation as a problem in a multidisciplinary, research or professional environment, and take an active part in finding a solution.
Follow a systematic method with an overall approach to divide a complex problem into parts and identify the causes by applying scientific and professional knowledge.
Design a new solution by using all the resources necessary and available to cope with the problem.
Draw up a realistic model that specifies all the aspects of the solution proposed.
Assess the model proposed by contrasting it with the real context of application, find shortcomings and suggest improvements.
 CT5 Produce quality texts that have no grammatical or spelling errors, are properly structured and make appropriate and consistent use of formal and bibliographic conventions.
Draw up texts that are structured, clear, cohesive, rich and of the appropriate length, and which can transmit complex ideas.
Draw up texts that are appropriate to the communicative situation, consistent and persuasive.

  Description
Introductory activities Activitats dirigides a prendre contacte i recollir informació dels estudiants. També es farà una presentació de l'assignatura descrivint els objectius d'aprenentatge, continguts, metodologies, sistemes d'avaluació i competències que es treballaran.
videoconferencing Presentation of subject contents and/or activities presentation through webconference. This activity requires synchronous presence of students and faculty. Its development allows different degrees of interactivity depending on the intended objectives. This activity can be recorded at the time of its development to facilitate subsequent consultation.
Reading written documents and graphs Reading and working of documentation published in different formats, with the aim of facilitating the development of competences with more theoretical nature and acquire the knowledge necessary for the development of practical activities.
Webcasting Presentation of subject contents in previously recorded video format. This activity does not require synchronous presence of students and teachers and does not allow interactivity directly. However, it can be used to propose asynchronous interactive activities such as a forum.
Problem solving, exercises Analysis and resolution of a problem or concrete practical exercise related to the topic of the subject. This activity has a more limited scope and a smaller extension than the assignments. This activity has a more limited scope and a smaller extension than the assignments.
Forums of debate Activities in which, individually or in groups, the participants argue and confront ideas on a specific topic, by using asynchronous tools such as the Virtual Campus Forum.
Practical cases/ case studies Statement of a situation (real or simulated) in which the student must work to give a solution to the topic, solve a series of specific questions or make a global reflection.
Self-monitoring activities Activities proposed to the student, with a minimum weight, which serve so that the student can self-regulate their learning.
Personal attention Planificar, guiar, dinamitzar, seguir i avaluar el procés d'aprenentatge de l'estudiant tenint en compte el seu perfil interessos, necessitats, coneixements previs, etc.) i les característiques / exigències del context
