It is suggested to have knowledge about Physics and Mathematics to fully understand the topics dealt with by the course

Main book is: Yunus A. Çengel, Giuliano Dall'Ò, Luca Sarto. Fisica tecnica ambientale. Con elementi di acustica e illuminotecnica. Editore: McGraw-Hill Education. Some slides will be shared with the students and they represents part of the didactic material.

not mandatory

The exam includes a written test and an oral exam. The written test consists in solving an exercise on one of the topics addressed in class; The oral test consists of a discussion of no longer than 30 minutes aimed at verifying: - the knowledge of the theoretical methodological content of the course; - the correct presentation of the applications proposed in the course; - autonomy in proposing the most appropriate approach for each scope. The oral exam will also test the student communication skills and his autonomy in the organization and exposure of the theoretical topics. The final evaluation is carried out by the Commission as the average value of the written test and the oral exam. It is noted that both oral and written tests must result at least sufficient in order to pass the exam. For Erasmus students, it is possible to have the oral test in English. If requested at least one week in advance also the written test can be translated to English.

In the classroom, lecture with the possibility of slides or supporting exercises.

The Course will cover the following topics: - Basis of energy analysis and thermodynamics (25 hours) - Heat Trasnfer (40 hours) - Ligthing Systems (10 hours) - Renewable energy (15 hours) - Exercise (10 hours)

Attendance is optional but is strongly recommended

The exam includes a written test and an oral exam. The written test consists in 10 multiple questions and 2 exercises on topics addressed in class; The oral test consists of a discussion of no longer than 30 minutes aimed at verifying: - the knowledge of the theoretical methodological content of the course; - the correct presentation of the applications proposed in the course; - autonomy in proposing the most appropriate approach for each scope. The oral exam will also test the student communication skills and his autonomy in the organization and exposure of the theoretical topics. The final evaluation is carried out as the average value of the written test and the oral exam. Both the written and the oral exams must be at least sufficient to pass the exam.

The course will happen in a traditional way with classroom lessons with the use of power point presentation
