In the heart of the bustling city of Barcelona is a square that at first sight seems like an oasis of calm. The Plaza del Sol, as the name suggests, is a suntrap and the perfect place to while away a few hours.
The problem is that the square is just too popular and for many of the city’s young inhabitants has become the number one venue to meet friends and hang out until the small hours.
One resident said it was like living in a permanent party.
Even the shops around the square reflect its reputation for late-night carousing, selling beer, pizza and little else.
The situation had become unbearable for those with apartments around the square, who have lived with unacceptable noise levels for the past 20 years.
Step in Barcelona’s fabrication laboratory, one of a network of 1,200 workshops around the world that allow people to test out new designs and ideas, and build products and new technology using a range of cutting-edge tools. Labs share their designs online so that something built in Boston can be replicated in a lab in Shenzhen.
With the help of some EU money, the lab built low-cost, easy-to-use sensors that can detect air pollution, noise levels, humidity and temperature.
“This was not only about being part of a scientific project but about enabling political action,” said Tomas Diez, who runs the lab.
Families placed the sensors on their balconies and were able to demonstrate that night-time noise levels – with peaks of 100 decibels – were far higher than World Health Organization recommendations.
Armed with this information, the residents went to the city council, pressing them to rethink the use of the plaza.
Police now move people on at 23:00. Rubbish lorries, which had previously cleared up when the partygoers left in the early hours, have been rescheduled for the morning, and steps that provided seating for gatherers have now been filled with plant boxes.
“Now the square is not just for people who want to party at night,” said Mr Diez.
His vision for fab labs goes further, imagining them as a vehicle to allow cities to become truly self-sufficient. They can provide its citizens with technology to grow their own food, 3D-print new products whenever they need them and offer them the tools they need to fight the growing problems of urbanism.
He, along with other technologists, designers and architects, is backing a project known as Fab City – a collective of 18 cities from Europe, India, China and America – that aims to create more sustainable and productive cities around the world in the next 30 years.
The vision is partly idealistic, harking back to pre-Industrial Revolution days when people made their own clothes and goods and shopped locally.
But it is also about improving the environment, moving from a globalised world where goods are shipped from China in huge container ships to a place where people can pick up a blueprint from a fab lab and create products in their own city.
“We are trying to build a new productivity model for society, creating a new sustainable economy in cities where people can prototype and test ideas,” said Mr Diez.
The data collection in Barcelona was part of an EU project – Making Sense – that aims to empower citizens through “personal digital manufacturing”.
It is part of a wider attempt to rethink smart cities and put control back firmly in the hands of citizens.
“We wanted to end this top-down approach where cities go to companies and ask them to build infrastructure and then pretend that is a smart city,” said Mr Diez.
And along the way, he hopes to build a new type of digital economy, one in which citizens own and control their own data – what he calls “citizen-based infrastructure”.
