Thermodynamics and Heat Transfer fundamentals.

The course is organized in four modules as detailed here below: Building thermophysics (18 hours of lectures and exercises) Characterization of heat transfer through building enclosure. Opaque building envelope types and characteristics. Transparent building envelope performance and glass types. Calculation of the energy needed by a building to control air temperature and humidity (winter and summer time). Calculation of heating loads. Air-conditioning (32 hours of lectures, exercises and laboratory) Thermal comfort and air quality requirements for indoor environments. Systems and components for the control of microclimate based on the task performed and on the fluid used to condition the environment. Operating characteristics and typical configuration of different types of systems (heating, ventilation and air conditioning). Air distribution and extraction from the environment. Absorption systems for cold generation. Overview of energy use monitoring and control systems. Fundamentals of Acoustics (18 hours of lectures, exercises and laboratory) Acoustic fundamental physical quantities and units. Free sound field, confined field and semi-reverberated field. Physiological acoustics and standard audiogram. Requirements and methods for the evaluation of the acoustic comfort. Passive acoustic requirements and evaluation of noise disturbance. Standardization references. Control of noise for HVAC systems and indoor acoustic correction. Fundamentals of Lighting (12 hours of lectures and exercises) Lighting fundamental physical quantities and units. System and environmental requirements in the case of artificial lighting. Types of artificial light sources and of lighting equipment. Simplified methods for artificial lighting calculation. Requirements and methods for the evaluation of the visual comfort. Methods for providing natural light to indoor environments: environmental requirements and control techniques. Simplified methods for natural lighting calculation.

The students will carry out two laboratory experiences (HVAC systems and Acoustics) and obtain data for preparing assignments reports discussed during the exam. They will also carry out other assignments with a design approach related to building thermophysics and lighting. The exercises will be carried out in computer labs.

The presentations used during the lectures will be available for the students. The teacher will provide references regarding technical literature and regulations. • Course handouts • ASHRAE Handbooks, ASHRAE, Atlanta, 2014-2017. • Corrado V., Fabrizio E., "Fondamenti di Termofisica dell’Edificio e Climatizzazione", CLUT, Torino, 2012. • Cumo F., Piras G, Sforzini V., “Analisi energetica degli edifici – Elementi progettuali”, Società Editrice Esculapio, 2019. • Fracastoro G.

Exam: Computer lab-based test; Written test; Optional oral exam;

To be admitted to the written exam, the student must have uploaded on the website the reports assigned during the course. The exam consists of a written test made up of questions about theoretical aspects (60 minutes, using a personal computer in a computer lab with no access to any document) and of exercises (180 minutes, using a personal computer in a computer lab with the possibility to consult theory books but no solved exercises). The theoretical examination consists of 40 questions organized in 4 sections related to the 4 modules covered in the course. The number of questions for each section is allocated as follows: • 10 questions about Building thermophysics • 14 questions about Air-Conditioning • 10 questions about Fundamentals of Acoustics • 6 questions about Fundamentals of Lighting For each question, 5 alternative answers are proposed (identified as A, B, C, D, E).Only one answer is correct. The score is calculated as according to the following rules: • +1 point for each correct answer; • -0.25 point for each wrong answer; • -0.10 point if the answer is not given. The result of this part of the test is immediately available at its end of the test. Those achieving at least 20 out of 40 points in the theory test, can access the exercises part. This part includes one exercise on "Building physics and Air Conditioning " (16 points), one exercise on "Acoustics" (8 points) and one exercise on “Lighting” (8 points). To pass the exam, the examinee must fulfil all the following three conditions: 1. To achieve the minimum score 15/30 (20/40) in the theory part; 2. To achieve the minimum score of 15/30 (16/32) in the exercise part; 3. The arithmetic mean of the scores of the two parts (theory and exercise) must reach at least 18/30. An additional score ranging from zero to three points can be added to the final vote of the written test, thanks to the mandatory presentation of one of the five assignments given during the course. There is no upper limit to the score thus obtained. The oral examination consists of questions about the topics dealt with during the course. The student will answer the questions by using a blackboard and interacting with the teacher. To have access to the oral examination the student shall have reached at least 18/30 in the written part. The oral examination is mandatory for those who do not make the above mentioned presentation, while it is optional for all other students.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
