Our society always need more professionals to solve problems linked to our high energy consumption, while trying to provide us total general comfort.
The most “energy-consuming” sectors in our civil buildings are the thermal and the refrigerant systems, whereas the trend to use of energy produced from the renewable sources is in rise, thus we need to find proper solution(s) following the current laws and regulations instructed by the Italian government and the EU.
While applying the European law(s), for energy-efficiency on the civil buildings involves a deep analysis of & on the building-plant system; necessary to have sufficient knowledge to carry out successfully the study of the thermodynamics characteristics, for the same a survey need to be conducted on the data and all other useful information to determine the summer and the winter energy needs.
The main objectives of this course, first of all is to teach and educate the students the fundamental steps in projecting plants (thermal, Air-conditioning plants etc.) for civil buildings/structures and secondly, to create a mentality for the “Energetics”. Thus, this could help them to find the best solution(s) while designing i.e. to optimized the use of energy from traditional source(s) but by using the new high-efficiency system(s) and encouraging the energy use from the renewable source(s) and with the minimum impact on the surrounding environment.
These objectives only can be achieved with the help of a good knowledge of our national and European laws and regulations, with the application of the 1’U.R.E (Uso Razionale dell’Energia, i.e. rational use of energy)

Expected outcomes after following this course:
• familiarity to use the technical physics fundamental theories in the sector of the thermos-technical plants
• will be provided with basic fundamental knowledge with respect to current laws and regulations to estimate the energy need/demand of a building for both in the summer and winter seasons.
• ability to conduct a preliminary energy assessment quite easily and capable to propose different compositions of the plant designing.
• the projecting capacity and skills, while designing and sizing different civil-structure thermal plants with the help of different programmes for calculation and graphic designing.
• self-researching ability in finding out the technical specifications of the main elements of the thermal plants.
• the sufficient Knowledge to prepare a presentable project for the public administration or for a private firm.
• the capability to read and understand the functional plan of a Thermal Plant.
• a mentality for the “Energetics” which will push the student to design plants with high comfort but keeping in mind to respect the natural and surrounding environment.
• ease of communicative manner with world-wide peer professionals in the matter of their competencies.


The students would like to follow the Thermal Plant (impianti termotecnici) course must have the following knowledge:

Teaching Methods

Teaching mainly will be delivered in the form of classroom lessons and classroom exercises. In the Laboratory of “Technical Physics and Energy (Energetics)” the students will be shown different parts of the Plants and then will be followed by an educational tour to Citadella Universitaria di Monserrato.
The first exercise will be based on drafting a semi-executive project, respecting current laws and regulations, meant for both building structures and the related AC systems for summer or/and winter climate(s).
During the second part of the course, an exercise will be focused on projecting a heating and water-lifting system for sanitary water for a building, connected to a traditional boiler and flat plate solar thermal collectors.
The exercises consist of the thermo-technical verification of opaque and transparent structures, the calculation of energy requirements, the dimensioning of the main elements of the plants, of the opaque and transparent structure, to calculate the energy demand/need, to design the principle elements of the plant,
Total hours dedicated for classroom lessons: 39 hrs.
Total hours dedicated of Exercises: 15 hrs.
Total dedicated hours for laboratory work: 6 hrs.

Verification of learning

All the students need sit for an oral exam, where the students will have to present their calculations, CAD designs and final report of the projects based on the exercises given to them and carried out during the academic year.
Students need to demonstrate that they have learnt and gained sufficient knowledge by following this course.
The oral examination consists of three parts:
1. The first part of the exam is to verify the completeness of the exercises
2. The second part consists of n ° 3 questions i.e. to verify the methods and the solutions of the exercises, the processes & techniques followed while designing and sizing the plant, the ability to read functional plan and layout of a plant and the capacity to apply the knowledge gained during the course.
3. The third part will be consisting of n ° 2 questions i.e. to verify the basic theoretical knowledge used by the student during the design phase (Project realization and designing).
The final exam has a weightage total of 30 marks.
40 % out of the total examination score will be evaluated on the basis of the active participation in the exercise, the correctness and compete execution of the same.
The second part of the oral exam has a weightage of 30% out of total marks.
The third and the last part of the exam has a weightage, i.e. rest 30 % of the total marks.
The final exam has a minimum weightage of 18/30, only awarded when the student has basic elementary knowledge on the subject. While, 30/30 with lode can be achievable with demonstrable excellent knowledge on the subject
