Energy Management in Buildings

Recommended Prerequisites

1st cycle courses, in particular Thermodynamics and Fundamental of Heat Transfer.

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. Students are invited to explore computational tools ro perform numerical simultions. 

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:

- fundamentals of heat and mass transfer;

- thermal properties of materials and building envelope solutions;

- methodologies and simulation models to evaluate the thermal behaviour of building elements;

- experimental methodologies to evaluate the thermal behaviour of building elements;

- energy performance of buildings directive and national law;

- bioclimatic design, passive house concept and integration of renewable energies in buildings;

The learning technical and scientific outcomes of students will be applied in the studies of  building design of energy efficient buildings.
