00:01Each year, millions of tourists from around the world visit Pompeii.
00:05They admire its frescoes and archaeological ruins,
00:09but few of them will ever notice the solar panels
00:12installed on the roof of the ancient Roman Villa of the Mysteries.
00:30This is a small photovoltaic panel that produces energy to illuminate this villa
00:37which, a large part of the energy that is needed,
00:42comes from the roof installed here.
00:46While Pompeii is considering extending this solution to other areas of the archaeological park
00:52that are far from the electricity grid,
00:54the city of Evora in Portugal has also adopted similar technologies
00:59avoiding the visual impact of conventional solar panels like this.
01:04We have here these shingles installed on the rooftop of the city hall in Evora,
01:08but they are not normal shingles.
01:10They are made of a semi-transparent epoxy material
01:13with solar cells embedded in the middle of it,
01:16which generates electricity for the self-consumption of this building.
01:20We have around this area, around 20 kilowatt peak of PV shingles,
01:25as we call them installed,
01:26and their objective is to blend into the landscape architecture of this building
01:32to protect the heritage area aspect of Evora.
01:37Since 1986, Evora's historic center has been listed as a UNESCO World Heritage Site.
01:43PV shingles are among the solutions through which a European project
01:47is helping the city reconcile heritage preservation with the modern challenges of sustainability.
01:52Evora is a city of the World Heritage Site.
01:58And as a large majority of European cities have the obligation to preserve the historical center,
02:10to preserve the heritage,
02:12in the meantime, it cannot be stopped at the time.
02:15We have to advance in the sense of finding solutions that allow the historical cities
02:24to go to the encounter of what we have to solve today,
02:30which is the problem of carbonization.
02:34Among the solutions developed to make this possible,
02:37is one created by a small family owned company based in North Eastern Italy.
02:43The cup is a composite of resin,
02:45which is transferred to the first frame.
02:47We take the photovoltaic cells that we have already sold in the past,
02:51and put them in.
02:53Next, we take another frame,
02:56which is a composite made with loads of loads.
02:59The last step is to increase the stamp
03:03and finally remove the finished product,
03:06which is a composite of resin with the inside of the cells we have seen before.
03:09Solutions like this one, and the different technology adopted in Pompeii,
03:14send an encouraging message to the rest of the world.
03:18I believe that the lesson that Pompeii gives is that it can work here,
03:23in this place, so delicate, so attentive, so fragile and large,
03:29means that it can work everywhere.
03:32Glass roofs integrating photovoltaic panels and solar canopies
03:36installed in the courtyard of schools in the historic center
03:39are among the other solutions being tested in Evora.
03:42Together with Alkmaar in the Netherlands,
03:45the Portuguese city is assessing these innovations
03:47through the Positives project
03:49to evaluate their potential for replication across Europe.
03:52, and other questions too.
