The course aims to provide knowledge of the physical problems and technologies necessary for the analysis of the thermal loads of buildings and for the sizing of heating and air conditioning systems.
The objective is to allow students to acquire specific knowledge: on the relationships between the external climate, building envelope and indoor microclimate, on the heat exchange methods referring to building energy, on the main typologies of heating and air conditioning systems, on the sizing criteria of heating and air conditioning systems.
At the end of the course the student will be able to apply the knowledge in the design and management of the thermal systems, with specific competence and capacity of analise.
For an effective understanding of lecture topics, it is advisable for the student to possess basic knowledge of heat transfer.
No propaedeutic ties are provided.
The course is delivered in 2 weekly modules of 2 hours each per a total amount of 48 hours; it includes a lectures and classroom or laboratory exercises.
The exam consists of an oral exam on topics related to the course topics, during which a project work developed during the course will be discussed; the oral test is aimed at verifying the knowledge relating to the parts of the program not addressed in the project work.
The exam aims to assess whether the student has knowledge and understanding of the topics covered and whether he has acquired interpretative ability and independent judgment in specific cases.
The student must also demonstrate expository and argumentative skills that allow the transmission of his knowledge to the examiner.
The sufficiency threshold will be considered reached if the student shows knowledge and understanding of the topics covered at least in the general lines and shows useful application knowledge for the resolution of concrete cases.
The final vote will be awarded according to the following evaluation criterion:
30 - 30 and honors: complete, in-depth and critical knowledge of the topics, excellent property of language, complete and original interpretative ability, full ability to independently apply the knowledge to solve the proposed problems;
26 - 29: complete and in-depth knowledge of the topics, full ownership of language, complete and effective interpretative ability, able to independently apply the knowledge to solve the proposed problems;
24 - 25: knowledge of topics with a good degree of learning, good language property, correct and safe interpretative ability, capacity of correctly apply most of the knowledge to solve the proposed problems;
21-23: adequate knowledge of the subjects, but lack in the adequate grasp of the issue, satisfactory property of language, correct interpretative ability, limited ability to independently apply the knowledge to solve the proposed problems;
18 - 20: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative ability, ability to apply the basic knowledge acquired;
Insufficient: the student does not have an acceptable knowledge of the topics covered during the course.
