TECHNICAL PHYSICS M - Z
Academic Year 2023/2024 - Teacher: GIANPIERO EVOLAExpected Learning Outcomes
At the end of this Course, the students will acquire the basic notions of:
- APPLIED THERMODYNAMICS (with special emphasis on sustainable energy systems in buildings)
- HEAT TRANSFER, focused on Building Physics
- APPLIED ACOUSTICS, especially focused on room acustics, noise control and technical norms
In relation to these topics, the students will be also able to solve simple practical design problems.
