AIMS AND CONTENT

LEARNING OUTCOMES

The course introduces the fundamentals of heat transfer phenomena in its mechanisms (conduction, convection and thermal radiation) and shows some examples of practical application. The course provides also the fundamentals of the energy analysis of buildings and refers to the corresponding European and Italian regulations.

AIMS AND LEARNING OUTCOMES

At the end of course the student is expected to be able to:

• apply basic laws and models to the solution of simple heat transfer problems;
• understand engineering problems related to the building and its envelope;
• estimate the thermal loads of the building.

The student will also acquire:

• the ability to manage their social interactions, foster a collaborative attitude, and engage in constructive communication in different environments;
• the ability to develop their imagination and creativity, engage in critical thinking, and employ strategic thinking;
• decision-making autonomy, collaborative attitude, human and material resource management, coordination skills, negotiation abilities, and uncertainty management.

TEACHING METHODS

Lectures; computer-based exercises and design, both individually and in groups.

SYLLABUS/CONTENT

HEAT CONDUCTION: General heat conduction equation; boundary and initial conditions; the thermal resistance approach; critical radius of insulation.

HEAT CONVECTION: Fundamentals and preliminary analysis; equation for the conservation of mass, momentum and energy; forced convection in tubes; natural convection; correlations.

THERMAL RADIATION: Blackbody and gray surfaces radiation; radiation heat transfer: black surfaces and diffuse, gray surfaces.

Building envelope: losses and gains through opaque and glazed components, thermal bridges, Glaser analysis; ventilation loads; internal and solar gains; solutions to reduce the heating and cooling loads.

Fundamentals of thermal comfort, psychometry and air conditioning; thermal plant efficiencies; calculation of primary energy requirements in buildings.

This unit contributes to the achievement of the following Sustainable Development Goals of the UN 2030 Agenda: 4. Quality Education, 7. Clean and Affordable Energy, 9. Enterprise, innovation and infrastructure, 11. Sustainable cities and communities, 13. Fighting climate change.

EXAM DESCRIPTION

Oral examination; the students, divided into groups, will also be required to submit a project consisting of the calculation (using finite element software) of an assigned thermal bridge and the preparation of the corresponding calculation report.

ASSESSMENT METHODS

The oral examination in based on a specific topic among those presented during the course, with in addition a couple of short questions on other one/two subjects.

The aim of the examination is to assess the student knowledge and the skill in reasoning and subject presentation.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it  ), the Polytechnic School's disability liaison.
