Type of delivery of the course

The course includes a series of lectures by the lecturer in which the topics covered by the course program and a series of recurring exercises to check the level of general learning. Due to the Covid-19 emergency, the teaching method takes place remotely through the use of a series of platforms that allow the transfer of teaching materials and the monitoring of the students' learning status. The moodle platform, teams, the uploading of audio and video lessons through one drive and the email are the tools used. For any information : https://architettura.el.uniroma3.it/mod/folder/view.php?id=409

Attendance

Attendance is reccomended for at least 75% of the lessons

Type of evaluation

The exam includes a remote oral interview on the teams platform as required by article 1 of the rector's decree of 5 May to respect the restrictions imposed by the covid emergency situation

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.

Attendance

The method of attendance of the teaching: 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 the case of buildings and architecture. At the start 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.
