Water plays an important role in buildings. Think about water supply coming daily to our homes: an efficient water supply system greatly contributes to quality of life and increases building sustainability. In a context of climate changes, with long periods of water scarcity, a responsible management of water resources is mandatory also at the building scale. New trends are developing towards this goal (rain water harvesting, the use of vegetation, etc.). In this course, after covering the basic principles of hydraulics, attention will be paid to the design of the building water systems in view of a sustainable use of the water resource.

After attending the course, the student is able to understand and manage hydraulics issues related to buildings, to read technical reports and national regulations dealing with water topics, to join new trends for water smart solutions at the building scale.

Calculus, mass geometry, basic knowledge of mechanics.

BASIC KNOWLEDGE OF HYDRAULICS Fluids properties; Statics of fluids; Fluid kinematics; Dynamics of perfect fluids, Bernoulli’s theorem; Dynamics of viscous fluids; Water distribution networks; Devices to measure flows and pressures. WATER SUPPLY SYSTEMS FOR BUILDINGS Principles and criteria for the design and validation of water distribution systems at building scale. DRAINAGE SYSTEMS FOR BUILDINGS Principles and criteria for the design and validation of drainage systems at building scale. NEW TRENDS TOWARDS GREEN WATER USES The water cycle at the building scale; Reuse of waste water; Rain water harvesting; The use of vegetation for sustainable water uses in buildings.

During the course theoretical lessons and exercises are carried out. For practical applications the same building that is considered in other teachings will be used. Working groups are usually made by 3 persons.

Modalità di esame: Prova scritta (in aula); Prova orale obbligatoria; Elaborato progettuale in gruppo;

Exam: Written test; Compulsory oral exam; Group project;

... The exam is made up by a written part (up to 30 scores) and an oral part (up to 30 scores). The final mark is made by the average of the scores obtained in the oral and in the written part, both of which must reach 18/30. If the mark of the written part is inferior than 18/30, the candidate is not admitted to the oral part. The written part assesses the ability to solve problems and some basic knowledge of the subject through 2 open exercises and 3 short questions (eventually quiz). No kind of material can be used during the written part, duration 1 hour. In the oral part, usually two questions, the design exercise and the topics carried out during all the classes are subject for the exam.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

Modalità di esame: Prova orale obbligatoria; Prova scritta su carta con videosorveglianza dei docenti; Elaborato progettuale in gruppo;

The exam is made up by a written part with exercises (up to 15 scores) and an oral part (up to 15 scores). The candidate has to reach 9 scores in the written part to be admitted to the oral part. The exercise and theoretical developments carried out during classes are topics for the exam.
