ING-IND/11 6 B - Caratterizzanti Discipline fisico-tecniche ed impiantistiche per l'architettura
The disciplinary laboratory of Building Physics and Energy Systems in Architecture is inserted in the MSc in Architecture Building City
and is aimed at providing students with knowledge of acoustical, lighting and energy topics applied to architectural projects. Another objective is that of making students conscious of the cultural richness, the requirements, the methodologies and the tools typical of building physics, in order to be able to carry out a disciplinary thesis on these themes.
At the end of the program, students will achieve the ability to apply this knowledge in architectural design that is a complex context in which building physics requirements may sometimes conflict or heavily influence the design phase.
Specifically, students will be able to understand design requirements, to consider regulations and technological restrictions, to use
more appropriate numerical or analytical calculation tools, know parameters to evaluate and approve a building physics project, and have the ability to make choices that involve different aspects of a building project.
Risultati di apprendimento attesi
This teaching is aimed at providing architects with a basic knowledge of building physics phenomena linked to design process.
Students acquire the knowledge required to dialogue with the various disciplinary skills, which operate in this process. During the teaching, students have the chance to test their achieved knowledge through a specific design activity.
In particular, at the end of the program students will acquire the following:
- Knowledge of physical concepts at the base of thermal fluid-dynamic, lighting and acoustic phenomena related to indoor
- Knowledge of building physics design requirements;

Prerequisiti / Conoscenze pregresse
Students are requested to have the basic concepts of building physics applied to indoor environment (lighting, acoustics and
air-conditioning), already achieved during the bachelor degree.
In particular, the following knowledge is considered as achieved:
- Basics of fluid-dynamics, thermodynamics, heat and mass transfer, lighting and acoustics;
- Principles of thermal building-physics;
- Principles of daylighting;
- Principles of sound absorption and sound insulation;
- Main materials and construction technologies used for keeping under control the above-mentioned phenomena.
And abilities:
- Ability to make conscious choices related to the building physics design;
- Ability to calculate performance and to verify the main thermal-hygrometric, energy, lighting and acoustic requirements related to the building envelope and to the indoor environment.
Some building physics issues will be proposed to the students, which appear with frequency during design process. For each issue,
professors provide a building physics interpretation of the topic and a methodology for an in-depth examination of the problem, in
order to identify the best technological solutions according to regulations and indoor comfort requirements.
In particular, the following topics are covered:
The teaching is a 6 credit program (60 hours): 35 hours are destined to lessons on theory, while about 25 hours are for the design activity (exercises given by professors and times dedicated to review design activity). For this teaching, the total study load range is
between 150 and 180 hours (between 25 and 30 hours per credit), which includes attending lessons, design activity and study.
- Principles for nearly-Zero Energy Building design and for existing building retrofit (6 hours);
- Audit principles and building energy survey (9 hours);
- Design requirements related to indoor air quality and thermal comfort (3 hours);
- Building envelope thermal design (6 hours);
- Techniques for natural ventilation and air-conditioning for indoor environment; Ventilation and air-conditioning systems (3 hours);
- Building energy systems design (3 hours);
- Renewable energy sources technologies (6 hours)
- Building energy evaluation (12 hours)
- Cost optimal analysis for building design (3 hours);
- Financial valuation (9 hours).
Considering the topics covered during the program, each student has to make evaluations related to building physics regarding an
architectural project with the support of manual calculation or automatic tools. These evaluations represent design activities
specifically related to energy efficient buildings and systems.
Critical analysis on evaluation results demonstrates that students have achieved the ability to face building physics topics during the
design phase; they will reach this goal in an autonomous way, consciously and with the competence typical of an architect.
Organizzazione dell'insegnamento
The development of a specific design activity is required in order to apply the achieved knowledge. Design topics could be carried out as a teamwork, with three or four students, or by a single student.
In order to help students with their design activity, professors provide numerical exercises on topics covered during the teaching.
Preferably, work reviews take place during lesson time, even though checks could be possible on other days and times, arranged with the professors, by appointment. Each work group has a maximum of three or four reviews, which will be concluded by the end of the lessons.
Every group is required to write a report, where the following data are collected: design requirements, schemes and sketches representing the adopted solutions, calculations, results and conclusions. In addition, they have to create a power point presentation, where requirements, project solutions, results and conclusions are reported in a synthetic form. The power point presentation will be illustrated during the final exam.
In the classroom there could also be a tutor to help the students. For particular situations, the professor will be at students disposal for any clarification about lessons, only by appointment (e-mail).
The use of EXCEL or MATLAB is recommended for calculations; the use of drawing tools is also required. By the end of the teaching, students will upload the design work on the teaching portal, on the dedicated page, in the section called "Elaborati". By the first exam date, the project work will be corrected and it will be valid for more sessions. After the end of the lessons, no more reviews with the professors will be possible.
In addition, if the number of attending students is compatible, technical visits to construction sites will be organized.
Testi richiesti o raccomandati: letture, dispense, altro materiale didattico

Usually, professors use ppt presentations, which are uploaded on the teaching portal, before the lessons. Extended documents on single topics, prepared by professors, form additional teaching material.
Students who want to examine the topic in-depth, can refer to the following books (further and specific references in English will be provided during the lessons):
- Rehva Guidebooks on HVAC Systems developed by Rehva (European Federation of Air Conditioning)
- ASHRAE Fundamentals developed by ASHARE (American Society of Air Conditioning)
- L.Stefanutti (a cura di), Manuale degli Impianti di Climatizzazione, Tecniche Nuove, 2007

- O. De Paoli, M. Ricupero (a cura di), Sistemi solari fotovoltaici e termici, CELID, 2007
For each topic covered during the lessons, the professors specify, on the teaching portal, which chapters of the reference books have to be examined in-depth.
In addition, during the lessons, other bibliography related to technical literature, to regulations and to industrial production of technological components and systems, will be communicated.
It is also suggested that the students visit the Documentation Centre "Laboratorio di Analisi e Modellazione dei Sistemi Ambientali"
(LAMSA), housed in Castello del Valentino.
Criteri, regole e procedure per l'esame
The learning control will be performed firstly through an oral test during which the design activity carried out by the group of students (or by a single student, if preferred) will be discussed, verifying specifically the knowledge acquired by each single group’s component about the contents of the shared work. To each student will be asked a minimum of two questions about the exercise developed, attributing an evaluation of maximum 30/30. Each student will also has to attend an oral interview about the theoretical contents of the course, which, in case of more than 15 students enrolled, could be replaced by a written exam composed by two open format questions, to which will be attributed a grade of maximum 30/30. None teaching material will be open to consultation during the entire exam.

With respect to the exercise part, the final mark will be defined as the average value between the evaluation attributed to the group’s work and the one attributed to each student depending on the knowledge he individually acquired upon the work and evaluated during the interview. The design activity conducted and reported by each group will be evaluated depending on its achievement of the objectives with respect to correctness of the technical decisions (materials choice and their collocation in the project), exactness of calculations and compliance with law requirements.
With respect to the theoretical part of the exam, the grade will be based on the contents of the answers provided, on their extension and deepness and on the terminology employed.

The final mark will be based equally on the design activity and on the theoretical part, taking into account also, for both parts, clarity, ability to synthesis and properties of languages demonstrated be the student.
