Syllabus
Course Objectives
The module is designed to provide the necessary knowledge of the principles and laws governing the thermophysical behavior of buildings, in relation to the climatic conditions of the site and the quality of the indoor environment. The aim is to develop the skills required to understand the parameters and procedures used to assess the overall energy performance of buildings and to verify compliance with the legal requirements for both existing and newly constructed buildings.
A specific focus of the course is on the procedures and methodologies aimed at the energy certification of buildings. The ultimate goal is to equip students with the knowledge needed to apply the main design procedures for building envelopes with a view to optimizing the overall energy efficiency of the building in relation to the site-specific climatic conditions, ensuring the achievement of comfort requirements, verifying compliance with legal standards, and preparing the corresponding energy certification.
Course Prerequisites
For an effective understanding of lecture topics, it is advisable for the student to possess basic knowledge of heat transfer.
No propaedeutic ties are provided.
Teaching Methods
The course is delivered in 2 weekly modules of 2 hours each per a total amount of 48 hours; it includes a lectures and classroom or laboratory exercises.The course is delivered through theoretical lectures and classroom or laboratory exercises, the latter aimed at further exploring and consolidating the topics covered during the lectures.
Assessment Methods
The examination consists of an oral test on topics related to the course content, during which a project developed throughout the course will also be discussed.
The assessment aims to evaluate whether the student has acquired knowledge and understanding of the topics covered, as well as interpretative skills and independent judgment in practical cases. The student must also demonstrate communication and argumentation skills sufficient to convey their knowledge effectively to the examiner.
A passing grade will be awarded when the student demonstrates knowledge and understanding of the main topics, at least in general terms, and shows adequate skills useful for analysis of practical cases.
The final grade will be assigned according to the following evaluation criteria:
30 - 30 cum laude: complete, in-depth, and critical knowledge of the topics; full proficiency of technical language; comprehensive and original interpretative ability; full capacity to independently apply knowledge to solve the proposed problems.
26-29: complete knowledge of the topics; excellent proficiency of technical language; comprehensive and effective interpretative ability; good capavity to independently apply knowledge to solve the proposed problems
24-25: good knowledge of the topics; good proficiency of technical language; correct and confident interpretative ability; able to correctly apply most of the knowledge to solve the proposed problems
21-23: adequate knowledge of the topics but lacking full mastery; satisfactory command of technical language; correct interpretative ability; limited capacity to independently apply knowledge to solve the proposed problems
18-20: basic knowledge of the main topics; basic knowledge of technical language; sufficient interpretative ability; ability to apply only the most essential acquired knowledge to solve the proposed problems
Not-sufficient/fail: the student does not possess an acceptable level of knowledge of the topics covered during the course.
