In a bid to bring greater green space to Barcelona, local architecture firm has proposed converting the city’s Camp Nou football stadium into a 26-hectare forested park. Dubbed Nou Parc, the design blankets the Camp Nou stadium and surrounding facilities with an undulating green roof千亿体育网址 strong enough to support a forest of trees. The architects estimate that the resulting park space could produce 15,000 kilograms of oxygen per day and absorb 25,000 kilograms of carbon dioxide daily.

Opened in 1957 as the home stadium of FC Barcelona, the 99,354-seat Camp Nou football stadium is the largest stadium in Spain and Europe. According to the architects, less than 10% of the stadium grounds have been allocated to green space, which results in an urban heat island effect and also creates a divide between the neighborhood of Les Corts from the University Area. When the stadium is not in use for sports events or private functions, the massive area is typically disused.

The Nou Parc proposal aims to bring greater functionality to Camp Nou with a publicly accessible green and leisure space that would not only better link the nearby neighborhoods but also improve urban air quality. The new park would be created in collaboration with tech company Verdtical so that the undulating green roof blanketing the buildings would be controlled by sensors and artificial intelligence capable of minimizing water consumption. Rainwater would also be collected and stored in two onsite lakes for irrigation of the park.

“Renaturing cities and gaining quality space for citizens is no longer just an interesting idea, it is a necessity,” said Jordi Fernández, co-founder of ON-A Architecture. “We are aware that cities must be re-naturalized, and that green provides unquestionable benefits for health, but the issue is not only green, the debate revolves around blue as well: the water. We cannot be green if that implies an excessive use of resources. The technology for the control of water consumption has come a long way and allows us to innovate and optimize green areas in urban spaces.”
