Hygrothermal behavior of facades

Recommended Prerequisites

2nd Cycle Studies.

Teaching Methods

The theoretical and practical contents of the curricular unit will be presented through lectures illustrated whenever possible with practical cases. Students are encouraged to apply the competences acquired through practical and laboratorial activities, and to develop and to discuss research works.

Learning Outcomes

The principal aim of this course is to promote the study of hygrothermal behaviour and energy performance of buildings. The purpose is to provide theoretical, practical and research skills of students in the following fields:
- thermal behaviour methodologies and simulation models;
- thermal properties of materials and building envelope solutions;
- building design of energy efficient buildings;
- energy performance of buildings directive and national law;
- bioclimatic design and passive solar systems;
- influence of the urban-scale systems organization on the internal thermal comfort levels of buildings and energy efficiency.
