Technical systems in buildings
Learning outcomes of the course unit
The training objectives of the integrated course provide that each student acquires knowledge and skills relating to air conditioning systems and to electrical systems in buildings. The course aims at providing the knowledge and skills (ie the ability to apply the knowledge) necessary for the plant engineering analysis of the buildings and each of its sub-groups. To develop the necessary threshold skills required in the study of any component of the installations in buildings, the student is asked to demonstrate the achievement of knowledge and skills on the following aspects of particular importance.
1) To know the theories underlying the mathematical models of simulation of the components of the thermal and electrical system;
2) identify the critical points that can be improved, evaluate the uncertainties and tolerances inherent in each calculation method;
3) analyze any component of the thermal and electrical system to verify if it meets the required efficiency requirements;
4) identify the dominant parameters in the choice of a system or a component, define its dimensions and characteristics;
5) know how to propose the appropriate design changes to increase the performance and efficiency of each system or component of the plants;
6) identify the constraints imposed by the functional requirements and the characteristics of the systems and materials;
7) know the nomenclature and terminology, both scientific and normative, also in English.
At the end of the training activity, in agreement with the Dublin descriptors, the student must have acquired knowledge and understanding, independence of judgment, communication and display skills, ability to learn and communicate. It must also have acquired the ability to evaluate the performance of the components of a system and to preliminarily design air conditioning and electrical systems.

Course contents summary
Heating and cooling systems in buildings. Electrical installations. The contents are described in more detail in the two individual modules, which deal with completely different subjects.
The two extended programs of the integrated course are described in detail in the two individual modules.
Teacher's clipboard and papers, available on line for the students.
University Educational Credits (CFU) 6, 48 hours in the classroom (24 hours of lessons, 24 hours of practice). Teaching is the cognitive framework aimed at setting up, consolidating and evaluating to promote acquisitive processes. The teaching method includes lectures, Socratic heuristic lessons, case studies, exercises, cooperative learning, project work. All teaching material is readily available or uploaded to the Elly platform. The total study load for this teaching module is between 150 and 180 hours, ie between 25 and 30 hours for each credit. This includes the hours in class, the completion of the exercises, the study. Each student has the faculty, in full autonomy, to increase the hours of study. At the time of class corresponds an equal number of hours of classroom exercises closely related to the lessons, during which the student is confronted with solutions to problems or small projects to develop the ability to apply knowledge to real problems as they arise practically. The teacher explains the traces of development and solution on the blackboard. Continuous assistance is provided; the teacher is always available by appointment and provides assistance or advice by e-mail, at any time. We recommend the use of Excel or Matlab for the numerical solution of the exercises.
Assessment methods and criteria
Written exam, for each of the two individual courses, to be preferably passed on different dates.
For each of the two courses, there is only the final written exam, which ascertains the acquisition of knowledge and skills by conducting a test lasting 120 minutes, without the aid of notes, books or computer tools.
The written test consists of problems, which span the entire program of the course, involving all the main topics. The answers require knowledge and application of skills. The questions correspond to the various parts of the chapters illustrated through the lessons and exercises. Each question allows to obtain an adequate score; the correct answer to each question allows you to get the grade 30 and praise. Students receive detailed information on the correction criteria and receive extensive information to avoid misunderstandings regarding the comprehension of the text of the exercises.
The aim of the analytical graduation of the student's performance is the reliable and objective evaluation of the level of achievement of the expected learning outcomes.
