EFFICIENTAMENTO ENERGETICO DELL'AMBIENTE COSTRUITO

Expected Learning Outcomes

Upon completion of the course, students will acquire the fundamental theoretical and methodological knowledge for the energy analysis of the built environment. Specifically, they will understand:

• Building physics and thermophysics: Heat exchange mechanisms in the building envelope (conduction, convection, radiation, air and vapor permeability).

• Industry regulations: European directives (EPBD) and national/international technical standards for energy modeling and building classification (nZEB/ZEB).

• Building systems: Operating principles of air conditioning, controlled mechanical ventilation (CMV), and integration with renewable energy sources.

• Sustainable mitigation strategies: Insulation techniques, thermal bridge correction, use of low environmental impact materials, and integration of bioclimatic design strategies.

Applying Knowledge and Understanding

The student will be able to apply theoretical knowledge to solve complex problems in environmental and territorial engineering:

• Energy diagnosis and modeling: Ability to model a building's thermal balance in both steady-state and dynamic conditions using specialized software.

• Intervention design: Develop suitable technical solutions for the efficiency of existing buildings and the design of new zero-impact buildings.

• Integrating the building into the territory: Evaluate the interactions between the built environment and the surrounding microclimatic/territorial context (e.g., urban heat islands, availability of local renewable resources).

Making Judgements

The student will develop the ability to critically evaluate and select the best efficiency strategies:

• Cost-benefit and sustainability analysis: Compare different technological alternatives, considering not only energy savings, but also environmental impact and economic and financial feasibility.

• Data Interpretation: Critically analyze and process data from energy audits, thermographic surveys, or numerical simulations to identify critical issues in the building-plant system.

• Ethical and Professional Choices: Make design decisions geared toward ecological transition, living comfort, and reducing the carbon footprint.

Communication Skills

Students will acquire the skills to effectively communicate the results of their technical work:

• Technical Report Writing: Ability to draft energy audit reports and energy performance certificates (EPCs) using formal and appropriate language.

• Interdisciplinary Presentation: Ability to present and defend design choices to both specialist and non-technical audiences.

• Graphical Representation: Use technical diagrams and energy graphs to clearly illustrate the building's thermophysical performance.

Learning Skills

Students will develop the ability to continuously update their knowledge, which is essential in a rapidly evolving sector:

• Regulatory and technological updates: Ability to independently consult and assimilate developments in technical regulations and innovations in energy efficiency materials and technologies.

• Use of research tools: Ability to locate and analyse scientific literature, climate databases, and product data sheets.

• Further studies: Acquire the methodological foundations necessary to pursue a master's or doctoral degree in the field of energy and ecological transition.

The teaching method of the course consists of lectures, design exercises with application to proposed case studies, and the use of specific software.

This course foresees the alternation between theoretical lessons and practical exercises on the issues discussed in theclassroom.

Design exercises relating to the production of energy through renewable sources will be assigned.

If the teaching will be given in mixed or remote mode, the necessary changes to what was previously stated may be introduced, in order to comply with the program provided and reported in the syllabus

Students must have a good knowledge of the fundamental principles of thermodynamics, heat transmission and the flux of matter and energy, addressed in the courses of technical physics of the three-year degrees.

Attendance at lessons is strongly recommended as it is consistent with the proposed training model which aims to encourage gradual learning, the active participation of the student in the classroom, and dialogue between teachers and students.

Information for students with disabilities and/or SLD

To guarantee equal opportunities and compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on the didactic objectives and specific needs.

It is also possible to contact the referent teacher CInAP (Center for Active and Participated Integration - Services for Disabilities and/or SLD) of the Department.
