The course covers topics plants aimed at understanding of all issues related to the electrical, heating and air conditioning systems, with basics for the sanitation and fire fighting systems in the construction with attention to sustainability. The course allows students to learn the techniques, the theoretical foundations and applications needed for the sizing of all systems, to understand the calibration mode of these plants and to size the heating and cooling power stations needed for the production of hot and chilled fluids.

The course of Thermotechnical Systems for Building deals with topics of "energy of buildings" and "plant engineering", aimed at the in-depth understanding of all the issues relating to heating, air conditioning, water-sanitary, fire-fighting and low voltage electrical systems, with particular regard to their sustainability, thus putting them in close correlation with the containment of energy consumption and the reduction of the environmental impact. The course allows students to be able to learn the techniques, the theoretical and applicative foundations necessary for the sizing of all the main heating and air conditioning systems, the hydraulic networks for the distribution of hot and chilled water, the aeraulic networks for the distribution of the air and of the supply and discharge networks of the water-sanitary systems, of the electric cables of the Low Voltage distribution. The course also allows students to understand and deepen the regulation methods of the aforementioned systems and to size the thermal and refrigeration plants necessary for the production of heat transfer fluids. In addition, the regulatory aspects from the fire prevention point of view of the most frequent activities subject to the control of the Fire Fighters will be dealt with in the course. The notions learned during the course will allow students to be able to deal with building-related designs with greater awareness and knowledge of all the significant interferences that normally arise between the architectural and structural design and that of the technical systems, in addition to verifying compliance with fire regulations. This preparation will allow for the correct development of the architectural projects of the buildings, but will also allow for the acquisition of plant engineering skills which can be aimed at professional placement in this sector. In order to learn the topics covered during the course, knowledge of the fundamental notions learned with the study of Technical Physics is required.
