La Domotica Possibile POLITECNICO DI MILANO Facoltà di Architettura e Società LA DOMOTICA POSSIBILE Caratteristiche, esperienze e stato dell’arte dell’ultima fase evolutiva dell’abitare RELATORE: Prof. OLIVIERO TRONCONI Tesi di Laurea di : DANIELA MEROLLA Matricola : 170216 ANNO ACCADEMICO 2008-2009 «Quello che infonde coraggio ai nostri sogni è la convinzione di poterli realizzare […] Non si rivoluziona facendo rivoluzioni, si rivoluziona portando soluzioni» Le Corbusier, Urbanisme (1967) Ringraziamenti Desidero ringraziare tutti coloro che mi sono stati vicini nel percorso finale di studi e che mi hanno dato la forza e lo stimolo per raggiungere questo importante traguardo. In modo particolare desidero dedicare questo lavoro a Cinzia, per la sua costante e amorevole presenza, lo spirito, le idee e l’incoraggiamento, ingredienti che sono stati decisivi per non perdere mai di vista il mio obiettivo. Un ringraziamento sentito va al Prof. Oliviero Tronconi che, accompagnandomi nell’intero lavoro, è stato una guida paziente, disponibile e fonte di continue sagge riflessioni. Ringrazio, quindi, mia sorella Milena per il gran cuore e la disponibilità totale, i miei genitori e tutti gli amici che mi hanno sempre sostenuta moralmente nell’ultimo anno. Molti approfondimenti sono stati possibili grazie al confronto con referenti di diverse aziende, consulenti - system integrator e installatori specializzati; in particolare desidero citare la collaborazioni con Daniele Leonardi dello staff di Vividomotica™ (Easydom) e con Diego Marchente della AVD Consulting (Home innovation). Grazie anche al mio amico Fabrizio, che ha collaborato più volte, con acume e senso critico, a conversazioni amene, ma fondamentalmente preziose nella comprensione dei temi tecnici per me più gravosi; infine un grazie speciale a Roberta, amica e paziente lettrice del mio lavoro. 5 INDICE GENERALE Ringraziamenti pag. 5 Indici » 7 Abstract » 23 Introduzione » 25 333PRIMA PARTE INNOVAZIONE TECNOLOGICA E FORME DELL’ABITARE CAPITOLO 1 - EVOLUZIONE DEL SISTEMA URBANO pag. 29 1.1 La città fortificata » 29 1.2 La città pre-industriale e la casa-bottega » 31 1.3 La città industriale » 32 1.3.1 L’industrialismo e i nuovi valori » 33 1.3.2 Razionalizzazione e monetizzazione » 34 1.3.3 La casa industriale: consumo e riproduzione » 35 1.3.4 La metropoli industriale culla del Modernismo » 36 1.3.5 La crisi della metropoli » 38 1.4 La città post-industriale » 39 1.4.1 I trend del mutamento: globalizzazione e conflitto » 40 1.4.2 La condizione postmoderna » 41 1.5 La città informatizzata » 44 1.5.1 Paradigmi dell’abitare contemporaneo: ubiquità e mobilità » 44 1.5.2 La produzione attuale: economia leggera e indifferenza spaziale » 46 1.5.3 La percezione della città: sostenibilità e spettacolarizzazione » 47 1.5.4 Internet e la rivoluzione informatica » 51 1.5.5 La città cablata: rete di servizi per la flessibilità abitativa » 53 1.5.6 Il futuro dopo il PC: domotica, nanotecnologie e cibernetica » 54 Conclusioni » 57 7 Indice Generale CAPITOLO 2 - EVOLUZIONE DEL SISTEMA DOMESTICO pag. 58 2.1 Esordi della meccanizzazione domestica » 58 2.1.1 La fabbrica entra in casa: la cucina di Francoforte » 61 2.1.2 La casa elettrica » 63 2.2 Applicazioni sperimentali per la casa del domani » 66 2.2.1 Il cinema e il design nella visione del futuro » 73 2.3 L’intelligenza artificiale » 76 2.3.1 L’intelligenza artificiale nell’automazione domestica » 77 2.3.2 Da una tecnica intelligente a un’architettura intelligente » 80 2.3.3 Familiarizzare con la domotica: gli elettrodomestici intelligenti » 81 2.4 Prodromi domotici » 83 2.4.1 Stati Uniti: Casa Ahwatukee, Xanadu, Smart House e la villa di Bill Gates » 83 2.4.2 Francia: Habiter Demain 2000 » 88 2.4.3 Italia: la Casa Telematica » 90 2.4.4 Giappone: Tron House » 93 2.4.5 Olanda: House of the Future » 94 Conclusioni » 96 CAPITOLO 3 - EVOLUZIONE DELLE FORME ABITATIVE pag. 97 3.1 La famiglia nella società italiana » 97 3.1.1 Diffusione delle tecnologie ICT in Italia » 101 3.1.2 Cyberspace, e-family, digital living » 108 3.2 La percezione del pubblico e del privato negli spazi domestici » 112 3.3 Aspetti concettuali dell’abitare » 115 3.3.1 L’abitazione come complessità » 117 3.3.2 Il bagno intelligente » 119 3.3.3 Le smart kitchens » 121 3.3.4 L’intrattenimento in soggiorno » 123 3.4 La domotica per l’assistenza ad anziani e disabili » 124 3.4.1 Requisiti dei sistemi integrati per l’utenza ampliata » 125 3.4.2 Trento e Aosta: edilizia pubblica domotizzata per fasce deboli » 127 8 Indice Generale 3.5 Il telelavoro » 132 3.5.1 Forme di telelavoro » 132 3.5.2 Pro e contro del telelavoro » 133 3.5.3 Stime » 135 3.6 L’edificio, il progetto e i nuovi vincoli energetici » 137 3.6.1 L’Italia, il quadro energetico e i consumi civili » 141 3.6.2 Le energie rinnovabili: da opportunità a necessità » 144 Conclusioni » 149 CAPITOLO 4 - EVOLUZIONE DEL MERCATO pag. 150 4.1 Le tecnologie d’integrazione dei sistemi: dalla CIB alla Domotica » 151 4.1.1 Building Automation e Home Automation a confronto » 154 4.1.2 Sviluppo del mercato domotico: da impianto a sistema integrato » 155 4.1.3 Integrazione impiantistica e progettazione evoluta » 157 4.1.4 L’automazione domestica, l’automobile e il pubblico » 160 4.2 I cambiamenti nel mercato » 162 4.2.1 La filiera della domotica » 164 4.2.2 Una nuova figura professionale: il system integrator » 166 4.2.3 Caratteristiche ed evoluzione del mercato italiano della domotica » 169 4.3 Il ruolo della ricerca e delle Associazioni » 175 4.3.1 L’esperienza di Homevolution » 176 4.3.2 Percezione della domotica e sviluppi futuri della domanda » 177 4.4 La domotica per un nuovo mercato immobiliare a valore aggiunto » 179 4.5 Potenzialità evolutive della domotica » 181 Conclusioni » 182 SECONDA PARTE LA DOMOTICA: DEFINIZIONI, TECNOLOGIE, PROGETTI, NORME CAPITOLO 5 - L’AUTOMAZIONE DOMESTICA » 185 5.1 La domotica: definizione » 185 5.1.1 Caratteristiche di un sistema domotico » 187 5.1.2 Le aree applicative della Domotica » 189 9 Indice Generale 5.1.3 Personalizzare un sistema domotico: gli scenari » 193 5.2 La realizzazione di un impianto domotico » 195 5.2.1 La scelta di un impianto domotico: soggetti e criteri » 198 5.2.2 Architettura base di un sistema domotico » 198 5.2.3 Schema di un progetto domotico » 200 5.2.4 L’analisi comportamentale e l’offerta domotica » 202 5.2.5 L’importanza del precablaggio » 204 5.3 Prime realizzazioni domotiche in Italia.

  • Connected Buildings
    the u-blox technology magazine No. 7 May 2019 Connected buildings The Internet of Buildings → 7 Connecting the workplace - tomorrow? → 22 Experimenting with Bluetooth mesh, inside and out → 50 Foreword Dear Readers, Do you talk to your home? And more importantly, does it listen? Just a decade ago, these questions would have seemed absurd. Today, they reflect reality in millions of households around the world, as the Internet of Things expands into – and enables – a new generation of smart, connected buildings. In this seventh edition of our u-blox magazine, we ex- amine how connectivity is transforming our homes, our workplaces, and the other buildings we inhabit, as well as the business opportunities that these new technologies create. But there’s more to this transformation than increasing our comfort, convenience, safety, and productivity. Ac- cording to The Global Alliance for Buildings and Construc- tion, in partnership with UN Environment, buildings are responsible for 40 percent of our CO2 emissions and 36 percent of our total energy consumption. That’s why they need to be front and center in our efforts to reduce our environmental impact while improving the quality of life of the growing, aging, and urbanizing world population. It’s a sector that plays to our strengths at u-blox, as pro- viders of wireless communication and positioning tech- nologies – key enablers of connected building solutions. That’s why we’d like to invite you to join us in exploring this Imprint rapidly evolving world – the great digital indoors. u - The u-blox technology magazine Published by: Thomas Seiler Chief Editor: Sven Etzold Senior Editor: Natacha Seitz We wish you an informative and enjoyable read.
