Teaching methods and learning activities
The teaching of this course unit is in accordance with the teaching practiced at the Faculty of Engineering. There is one theoretical class per week, in which students interact through reflection on proposed topics, lasting around 2 hours. In addition, there is one theoretical-practical class per week, lasting 1h30, in which exercises within the scope of the project are solved. Five exercises will be proposed to be delivered by students for assessment. In theoretical classes, PowerPoint presentations are used and made available to students. Students are provided with calculation tools in the field of thermal performance of buildings.
DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Establish processes leading to different conception solutions, design, construction and installations management in order to identify the most efficient. Calculate and organize information to identify best practices. Evaluate the results of application of methodologies to enable the choice of the best cost/efficiency ratio. To relate the results of several indicators in order to better identify the interactions between design solutions and the practical possibility to implement, use, maintain and preserve.

Eligibility for exams
Achieving final classification requires compliance with attendance at the course unit, according to the MEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.
Calculation formula of final grade
The final classification results from the following calculation formula:
CF=0.75.EF+0.25.AD
CF = final classification
EF = final exam
AD = distributed assessment
The final exam has a component corresponding to theoretical classes, valued at 10 points, and a component relating to practical classes, valued at 5 points.
The distributed assessment component consists of carrying out 5 exercises (in theoretical-practical classes and at home) and is valued at 5 points.
Observations
Estimated working time out of classes: 4 hours week.
