The course has the main goal to offer to the students both the awareness on the issues linked to energy saving in buildings, especially relative to refurbishment, and the possible leading-edge technological solutions.
Knowledge of the subjects of the course Technical Physics and HVAC Systems
Teaching will take place mainly through lectures with a special attention to a direct interaction with students, which will have the possibility to propose deepening of some subject and to debate on them.
Within the course, practical exercises will be solved concerning the design load for heating and cooling, energy performance of buildings in standard conditions and energetic refurbishment of building components finalized to provide students with a critical capacity on these subjects.
Additionally, a laboratory is offered (if financed) concerning FEM modeling of thermal bridges.
The written test is structured in two questions on theoretical subjects and an application exercise. Each problem serves for the assignment of a maximum of 20 points, for a total of 60. The final mark is out of 30 and is considered sufficient only by those candidates who achieve a score of not less than 16/30.
The individual project must be delivered to the teacher in due time to correct it and assign a mark in thirtieths. To obtain the sufficiency in this part of the exam it is necessary to obtain a minimum score of 16/30.
The final score corresponds to the arithmetic mean of the marks obtained in the written test and in the individual project. If the final score is less than 18/30 an oral exam is scheduled.
