Objectives

Justification:
Building pathology is responsible for huge repair costs, which is why it is essential to understand the physical mechanisms that justify the anomalies observed. The rehabilitation of built heritage is an area of great strategic importance, given the need to restore the monuments, ancient buildings and the first buildings of reinforced concrete frame structures that are deeply degraded.

Objectives:
- The acquisition of technical and scientific knowledge in the areas of hygrothermal behaviour, natural ventilation, Building Pathology and Rehabilitation of Buildings;
- The development of design procedures in these areas meeting the regulatory requirements and quality standards.

Learning outcomes and competences

Skills and Learning Outcomes:
Knowledge: Knowledge of the mechanisms of moisture transfer, natural ventilation and hygrothermal loads.
Understanding: Pathology studies of materials and components, including the measurements and surveys necessary for the understanding of the causes that are behind it.
Application: Integration of knowledge in the rehabilitation project.
Analysis: Ability to integrate a multidisciplinary approach.
Summary: Method for the preparation of rehabilitation projects.
Project Engineering: hygrothermal studies, studies of natural ventilation, building pathology studies of the construction and rehabilitation projects.
Engineering Research: hygrothermal behaviour and rehabilitation of buildings.
Engineering Practice: Implementation of rehabilitation and assessment of service performance.

Teaching methods and learning activities

The teaching is in accordance with the teaching recommended by FEUP There are 2 theoretical classes a week, of the explanatory type, with each class lasting around one hour. There is also one practical class a week, lasting 2 hours, where exercises are solved, assignments are done, and the subjects addressed are discussed. We seek to make sure the content of practical classes, whenever possible, is given in parallel with the theoretical classes. During theoretical classes, overhead and PowerPoint are used as a support for the exposition, which allows to better follow up on students and for them to visualize the content of the subject . Students have a class at the Building Physics Laboratory in order to contact with the equipment used for measuring temperature and humidity in construction materials and elements.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Integration of knowledge in the rehabilitation project. Ability to integrate a multidisciplinary approach. Method for the preparation of rehabilitation projects. Critical Sense. Hygrothermal studies, studies of natural ventilation, pathology studies of the construction and rehabilitation projects.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation Weight (%)
Exame 75,00
Trabalho escrito 25,00
Total: 100,00

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC 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 is calculated with the following expression: 


CF=0,75*EF+0,25*AD

CF = final classification
EF = final exam
AD = distributed evaluation

Special assessment (TE, DA, ...)

Identical evaluation for all students.

Classification improvement

Improving the classification can be made to one component or two, keeping the formula for calculating the final grade.

Observations

PRIOR KNOWLEDGE: Building Physics and Building Technology. The estimated time for work outside of class is 4 hours per week.
