«Smart cities», intelligence comes to an account

Los cambios suponen también una oportunidad para revolucionar la movilidad, el consumo energético, la sostenibilidad o el urbanismo

The "smart cities" or "smart cities" have come to take advantage of the millions of data generated by the information and communication technologies that surround us. The changes, which have been highlighted last week at the Smart City Expo World Congress in Barcelona (SCEWC), also represent an opportunity to revolutionize mobility, energy consumption, sustainability or urbanism with proposals that, in addition to being more responsible, are a help to the pockets.

In mobility, the improvements are obvious. Mobile applications, in the most popular example of the benefits of "big data", allow to share transport or improve traffic management. A recent study by the Texas Transsportation Institute estimated that traffic jams in North America can lead to a million-dollar bill of more than 11,300 million liters of gasoline and more than 7,000 million hours of bottled citizens: 960 dollars a year lost per traveler.

With endless opportunities, companies such as Seat, present at the fair, go beyond their traditional business. "So far the mobility apps have prioritized that we arrive faster but we have to inculcate a new line, to do it with more security or to generate less environmental impact," says ABC Jordi Caus, responsible for Smart Mobility projects of the firm. Thus, the Metropolis: Seat Lab is working on a socially responsible '' app '' together with Waze and Barcelona City Council.

The hall closes successfully: more than 21,000 visitors, 17% more than in 2017

In terms of sustainability, the data also offers a lot of ground to cover. According to a study by KPMG and Siemens, Spanish municipalities can save up to 60% of their spending with digital technology and, although it is still ahead, 70% of the municipalities are already halfway to being 4.0. Experts add that energy efficiency in the domestic sphere is one of the fields with the most potential.

Precisely Siemens is one of the 844 companies that present at the Barcelona fair. Among his projects, he highlighted his improvements in building performance through the power of data. Thus, directing from the same control point heating, ventilation, air conditioning, lighting, blinds, security, access control and electric power is possible energy savings of between 20 and 30%. This system also saves 40% in base costs and maintenance.

Savings in prevention
«The client does not have to pay for the change: the investment ends up compensating with the subsequent return», José María Piqué, regional delegate of Siemens in Catalonia, explains to ABC, recalling that «after all, the 90th % of the time of our life is spent in buildings and we do not pay much attention to them. We have to take care of them more, "he says.

In many cases, saving is given by prevention. T-Systems has brought to the SCEWC an innovative project to monitor the status of large infrastructures using sensors. "They are inserted between the concrete and can detect corrosion, moisture or cracks. Maintenance is saved and environmental standards are improved, "explains Eduard Contijoch, Industry 4.0 Business Development Manager of T-Systems Iberia. This system already works in the airports of Düsseldorf and Frankfurt or the port of Rotterdam and could have prevented the catastrophe in Genoa by the collapse of a poorly preserved bridge.

The same company is also working on projects for automatic counting of people on beaches – which would help to more efficient maintenance -, as well as solutions related to lighting: in Denmark a special device is being tested to guide the bodies with lights security to the place where an emergency occurs.

The improvement often goes beyond the economic. Bosch, for example, has shown a camcorder system that represents a breakthrough in security. With intelligent sensors, the systems collect in real time the flow of data about crowds or the detection of objects or heavy vehicles. This system already works in Seville during the Holy Week festivities: with 17 cameras in the historic center you can prevent avalanches and better attend the floods of people who are looking for processions.

Beyond specific projects, the Barcelona congress has corroborated that investing in the city of the future compensates. .
