Contents The course of Industrial Applied Physics offers learners teaching units aimed at learning the basic principles of classical thermodynamics, including the main modes of heat transmission and related applications in the construction field. The course also proposes the study and analysis of thermo-hygrometric well-being in a confined environment with particular reference to the main causes of discomfort for occupants and the treatment of the main types of air conditioning and air conditioning systems, also powered by renewable energy sources. There will also be an outline of the main thermal machines and related thermodynamic cycles. Finally, the main theoretical aspects related to architectural acoustics and lighting technology will be discussed in relation to Interior Design, Exhibit Design or Retail Design.

Slides from the lessons
Educational objectives The main objective of the course is to provide learners with theoretical knowledge and practical skills for the analysis of these phenomena and the recognition of the effects they cause on human health.
The main knowledge (Dublin Descriptor 1) acquired will be:
- theory of thermodynamics and heat transfer
- theory and technique of air conditioning
- theory and phenomenology of the internal and external microclimate of buildings
- basic elements of the different environmental phenomenologies and their effects on human health
- techniques of acoustic analysis and lighting in interiors and exteriors of buildings.
The main skills acquired (ability to apply the acquired knowledge, Dublin Descriptor 2, and to adopt with appropriate judgment the appropriate approach, Dublin Descriptor 3) will be:
- evaluate the principles of thermodynamics and the related application consequences
- analyze the main heat exchange mechanisms
- assess the quality of the internal environments and the microclimatic characteristics of the same
- evaluate the characteristics and the main acoustic and lighting engineering parameters and their effect on human health.
Prerequisites As for recommended preparatory steps
Teaching methods The course is divided into:
1) Theoretical lessons
