Type of delivery of the course

The course includes frontal lessons, exercises, and some practical lessons focused on the use of software and laboratory instruments to measure thermal comfort and thermo-physical properties of the building construction elements. Exercises or case studies will be carried out to apply the acquired knowledge. Supplementary didactic material will be provided on Moodle, at https://architecture.el.uniroma3.it In case of an extension of the COVID-19 health emergency, all the provisions governing the methods of carrying out teaching activities and student evaluation will be implemented. In particular, lessons and exercises will be carried out remotely, through the Teams platform.

Attendance

Attendance of the teaching is MANDATORY at 75% of the hours

Type of evaluation

Written and oral exams. The final exam consists of a written test and an oral test; the written test, lasting 2h30', includes exercises on the topics of the program (heat transmission, acoustics, lighting, thermodynamics), with the aim of verifying students' ability to apply what they have learned to real cases, relating to construction and to buildings. Comments and / or explanations of the procedure adopted may be requested, etc. The written test must be passed in order to take the oral test. The oral test takes place after the written test, and consists of questions on the topics of the program, with the aim of assessing the actual mastery of the concepts, and the ability to connect the various topics and apply them to buildings and architecture cases. At the beginning of the course, it will be considered whether to carry out intermediate tests (exercises), which, if passed, will exempt students from taking the written test. In case of closure for the Covid emergency, exams will be carried out through the Teams platform.
