Building Physics is that part of the science that studies the topics of energy efficiency in buildings and environmental comfort. Its field of action is not limited to the study of buildings but also extends to the environment outside at the various territorial scales.
The main purpose of the course is the study of the energy-environmental performance of buildings and the consequent connections with urban, architectural and plant design.
The topics necessary for understanding the interaction of the external environment - building - internal environment, the exploitation of energy sources (in particular regarding renewable energy sources) and the satisfaction of comfort are discussed.
The international legislative and regulatory framework is focusing in the last years, even in a mandatory way, the design choices in the building sector to an ever-increasing attention to the energy and environmental aspects of both new buildings, to almost zero-energy buildings, and those existing subjects to retrofit. The theoretical basis provided in this discipline are essential elements for a coherent approach to sustainable construction design.
An innovative teaching activity is planned in flipped classroom mode.
Risultati di apprendimento attesi
In this course, the basic elements for an energy efficient, environmentally friendly and sustainable design are provided. Specifically, the theoretical basis necessary for understanding the phenomena of Building Physics applied to the construction sector are provided.
Students will acquire the fundamental tools to assess the energetic behaviour of the buildings that they will have to plan or refurbished. Each of their technological choices can be assessed for the consequent energy implications. The basis of thermodynamics and heat transfer, and of sustainable design, once acquired will constitute a knowledge essential to manage the energy and environmental aspects of buildings.
By developing a deeper intuitive understanding of thermal sciences, the course allows students to approach the architectural design taking into account the physical phenomena responsible of the building behaviour. Moreover, by introducing the basics of the architectural science, the course provides knowledge of the physical principles and their relationship to human comfort, also by considering the control functions of the building (passive controls), associated installations, energy-using ‘active’ controls.
Since the performance of the built environment has greatest effect on energy use and sustainability, the lectures are finalized to study the interaction between buildings and environment, the environmental and energy problems and their connection with architectural design.
Basic subjects are thermodynamics, heat transfer, psychometrics, climatic conditions, thermal and visual comfort and their relation with energy and environmental performance of the buildings.

The knowledge gained equips the student with the tools to realize the potential of the good intentions of sustainable design.
The course structure includes ex-cathedra lectures with exercises.
During the educational path the sequence of the courses and the order of registration of the related exam must follow the priority specified in the study programme regulation.
Modalità di valutazione
The examination implies a written test:
• solving numerical problems • theoretical questions with multiple answers on the topics of the course • theoretical questions with open answers (succinct) on the topics of the course
Based on the verification needs of the teacher an additional oral examination could be eventually included.
