Contents	The course aims to provide a systematic and in-depth overview of technologies and design criteria for HVAC systems and renewable energy generation systems, with particular focus on applications in the building sector. It addresses the engineering, energy, and environmental aspects related to the integration of systems within the building-plant system, with a view toward sustainability, energy efficiency, and environmental impact reduction. The course also aims to develop analytical and design skills for the evaluation of energy and economic performance of building service systems, in compliance with national and European regulations on energy efficiency, sustainability, and emission reduction. Main Topics Renewable Energy Generation Systems Design and technological analysis of systems for thermal and electrical energy production from renewable sources (solar thermal, photovoltaic, biomass, wind, hydropower). Evaluation of energy, environmental, and economic performance indicators. Architectural and plant integration in buildings. Energy Efficiency of the Existing Building Stock Design strategies for enhancing the energy performance of existing buildings. Technologies for structural and system integration in energy retrofit interventions and post-event reconstruction (e.g., post-earthquake), with a focus on environmental compatibility of interventions. Environmental Impact and Emissions Analysis of pollutant emissions associated with energy production and use. Life Cycle Assessment (LCA) of energy systems and sustainability performance indicators. Principles of circular economy applied to the energy and building sectors.

Educational objectives	The objective of the course is to provide students with the knowledge, skills, and both qualitative and quantitative design capabilities related to the main energy systems applied predominantly in the civil sector, with particular focus on systems powered by renewable energy sources. The course also addresses the assessment of environmental risks associated with such systems and the main mechanisms of environmental protection and prevention. Students will acquire the fundamental tools necessary for the preliminary design and sizing of the studied systems, as well as for the analysis of the energy performance of the built environment — including buildings subject to environmental and architectural constraints — through the discussion of case studies and practical exercises, also involving the use of dedicated software tools. Main Learning Outcomes Knowledge: Understanding of the main technologies currently employed in the production of thermal, cooling, and electrical energy from renewable sources; Basic knowledge of the design principles of renewable energy systems; Familiarity with standard methodologies for the calculation of energy demand and building energy certification; Knowledge of the fundamental concepts related to HVAC systems for buildings; Understanding of the components (materials, technologies) and performance characteristics of energy system elements; Knowledge of methodologies for assessing environmental sustainability and life cycle impacts of energy systems. Skills: Analyze different types of energy generation systems; Use software tools for assessing the current energy performance of buildings (energy certification) and propose improvement measures in compliance with current energy-saving regulations; Develop a preliminary design for a thermal and/or electrical energy production system powered by renewable sources; Critically assess and propose solutions for a case study; Evaluate the environmental sustainability of energy systems through appropriate indicators and analysis methods (e.g., LCA, carbon footprint). The aim is to provide students with knowledge and competence needed for Renewable Heat and Power systems design and energy performance of buildings. The sizing criterions for the main components of renewable energy plants will be acquired. Main knowledge acquired will be: - Knowledge of the methodologies for buildings energy performance in compliance with statutory requirements; - Knowledge of the heating and HVAC systems for buildings; - Knowledge of the methodologies for designing renewable energy plants; - Knowledge of technical solutions (working mode and performance); The main competence (i.e. The ability to apply the acquired knowledge) will be: - Plant design solutions in compliance with current regulation on energy savings; - Design of a plant; - Choice and sizing of the main components of plants; - Plant design solutions in compliance with current regulation on energy savings; - Economic analysis of a proposed solution.
Prerequisites	In order to be able to understand and to apply the of the topics of the Course, students should know have the basic notions acquired in the Three-year Degree course, especially in the Applied Thermodynamics and Heat Transfer and Hydraulics courses. Knowledge of these notions is a mandatory prerequisite for attending the course with profit.
Teaching methods	E-learning activities + Face to face in class. Presentation of case studies and numerical examples in class. Possible field trips. The teaching material is available on https://www.unistudium.unipg.it/
Other information	Attending the lessons is optional, but strongly suggested. The students should develop a project (Term paper) which should be revised before the exam.
Learning verification modality	The exam consists of an oral test and the presentation of a work on topics regarding the teaching course, made by the students individually or in a group and concerning a case study. The oral test consists of an interview of about 20-30 minutes long in order to verify the knowledge level and the understanding capability acquired by the student on theoretical and methodological contents. The examination will also check the student communication skills and his ability in the exposure of the theoretical aspects.

Prerequisites	Knowledge of thermodynamics and fluid motion
Teaching methods	The course is organized as follows Introductory classroom lessons (8 hours) Delayed e-learning lessons (27 hours)
Other information	attendance is recommended
Learning verification modality	The exam includes an oral test. The oral exam consists of a discussion lasting about 30 minutes aimed at ascertaining the level of knowledge and understanding reached by the student on the theoretical and methodological contents indicated in the program (alternative internal combustion engines, turbomachinery, energy systems). the oral test will also allow to verify the student's communication skills with language properties and autonomous organization of the exposition on the same theoretical topics. The test may also consist, as a complement to the high tests, in the discussion of a case study proposed by the teacher, as a project carried out individually or in a group. The discussion will illustrate the problems posed in the assigned case, the possible project alternatives, any regulatory context, the methodological approach adopted, the analysis of the results obtained. The discussion can make use of a written report or about 10 slides and provide for the request for theoretical insights and detailed clarifications by the members of the examination commission. The test as a whole allows you to ascertain both the ability to know and understand, and the ability to apply the skills acquired, both the ability to exhibit, and the ability to learn and develop solutions independently.
