Smart city è un nuovo modello di città sostenibile proposto dall'UE la quale prevede investimenti di circa 11 miliardi di euro nei prossimi dieci anni per incentivare questo tipo di città, di medie dimensioni capaci di coniugare sostenibilità e competitività.
Smart City is a new model of sustainable city proposed by the EU which foresees investments of around 11 billion euros over the next ten years to promote this type of cities: a medium-sized cities that combine sustainability and competitiveness.
Le città oggi consumano il 70% dell’energia dell'UE, al fine di raggiungere un risparmio energetico significativo le istituzioni europee fanno leva per ridurre del 20% le emissioni entro il 2020 e al contempo per sviluppare un'economia “low carbon” entro il 2050. La formula individuata associa l’utilizzo più razionale delle risorse all’integrazione delle tecnologie pulite, in Europa si prevede la creazione di una rete di trenta smart cities da selezionare entro il 2020 caratterizzate da: mobilità sostenibile e dolce, fonti energetiche rinnovabili, uso di tecnologie intelligenti per la gestione delle risorse, dei servizi, del trasporto, dei rifiuti.Un progetto extraeuropeo di “smart city” (in corso di realizzazione) è quello di Masdar City Project, una nuova città che sta sorgendo a 15 km. da Abu Dhabi, prima città al mondo ad essere progettata e concepita come “Carbon Neutral”, cioè ad emissioni zero (progettista sir Norman Foster). Ospiterà a regime 50.000 residenti e circa 60.000 addetti lavoratori al giorno che saranno occupati in 1000 imprese attive nel settore della Green Economy. La superficie territoriale della città è di soli 2,6 chilometri quadrati, pertanto essa rappresenta un modello di città supercompatta (solo 52 mq./ab.). La forma della città è dettata da criteri climatici: il surriscaldamento delle pareti degli edifici viene vanificato dalle distanze molto ravvicinate tra le facciate, gli angusti spazi tra gli edifici favoriscono la ventilazione delle strade, a cui contribuisce anche la wind tower, posta al centro della piazza, una struttura conica che sfrutta le correnti d'aria che sorvolano gli edifici per ventilare gli ambienti cittadini. Le pareti degli edifici residenziali sono ricoperte da pannelli ondulati simili a terracotta con la funzione di brise-soleil e di ventilazione. Adottati criteri costruttivi delle case tipiche yemenite con grandi spessori perimetrali e camini di ventilazione naturale (a tal proposito si veda anche post precedente: http://citysmile.blogspot.it/2012/01/casanova.html#more.
E’ presente una centrale fotovoltaica ampia 21 ettari in posizione periferica, la mobilità in superficie si basa su spostamenti a piedi e in bici, gli ascensori sono nascosti alla vista per incoraggiare l'uso delle scale, le auto elettriche utilizzeranno una rete interrata su binari, la città si caratterizza anche per una protezione esterna dal traffico motorizzato: vere e proprie mura che impediranno l'accesso di qualsiasi oggetto inquinante.

The cities, today, consume 70% of energy, in order to achieve significant energy savings, the European institutions leverage to reduce emissions of 20% by 2020 and, at the same time, to develop low carbon economy by 2050. The challenge, associated with the more rational use of resources to the integration of clean technologies, in Europe is expected to create a network of thirty smart cities to be selected in 2020 in which will be: sustainable mobility, renewable energy sources, use of technologies for the intelligent management of resources, services, mobility, waste.
A project of a non-European "smart city", in progress, is Masdar City Project, the new city is rising 15 km far from Abu Dhabi, the first city in the world to be designed and conceived as a "Carbon Neutral" - zero emission (design by Sir Norman Foster), this city will hold 50,000 residents and approximately 60,000 employees working in over 1000 companies active in the Green Economy that will settle there. The land area of the city is only 2.6 square kilometers, so it is a super compact city model (only 52 sq. m. / each ha.). The shape of the city is designed by climatic criteria: the heating of the walls of the buildings is reduced by the very close distance between the facades, the thin spaces between buildings get a good ventilation in the roads, which also contributes by the” wind tower”, in the center of square, a conical structure which uses air currents flying over the buildings to ventilate the spaces of citizens. The walls of residential buildings are covered with corrugated panels with the function of brise-soleil and ventilation. There are adopted design criteria of typical Yemeni houses with large thick perimeter and chimneys for natural ventilation (in this regard see also previous post: http://citysmile.blogspot.it/2012/01/casanova.html#more.
And there is a photovoltaic power plant, 21 hectares large, the mobility is based on walking and cycling, the elevators are out of sight to encourage use of stairs, electric cars will use a network in underground rails. The city also has an outer protection from motorized traffic: real walls that prevent the access of any pollutant subject.
