Objectives
When intervening in a building to have the ability to: Part I: A- Understand at what time it was built and its cultural importance; B-Recognize your constructive and structural system; Part 2: Capacity to solve the problems of the mechanics of the material point systems and rigid bodies at rest
Program
Part I-Building science
I.1-Portuguese vernacular architecture
Description of construction systems, structural systems (operation and evolution), comfort conditions (thermal, natural light and noise) and nomenclature of building elements
Recommendations on how best to intervene to ensure the best conditions of habitability and security against possible earthquakes (horizontal actions).
I.2-Urban income buildings
Description of construction systems, structural systems (operation and evolution), comfort conditions (thermal, natural light and noise) and nomenclature of building elements
Recommendations on how best to intervene to ensure the best conditions of habitability and security against possible earthquakes (horizontal actions).

Evaluation Methodology
Part I (weight of 30% in the final average): A written test
Part II(weight of 70% in the final average): Weighted average of the results of the proposed studies during the period of classes (30%) and in the result of a written test (70 %).
Exam waiver: final grade equal to or greater than 9.5
Exam: Written test (Part I (30% weight) and Part II (70% weight))
