Comments Off on ON-A wants to renature Barcelona by greening the Camp Nou stadium

In a bid to bring greater green space to Barcelona, local architecture firm ON-A 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 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.  Related: ZHA gets the green light for world’s first all-timber soccer stadium in England 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.” + ON-A Images via ON-A

MIT moves toward greener, more sustainable artificial intelligence

Comments Off on MIT moves toward greener, more sustainable artificial intelligence

While current  artificial intelligence  (AI) technology holds strategic and transformative potential, it isn’t always environmentally-friendly due to high energy consumption. To the rescue are researchers from Massachusetts Institute of Technology (MIT) , who have devised a solution that not only lowers costs but, more importantly, reduces the AI model training’s carbon footprint. Back in June 2019, the  University of Massachusetts at Amherst revealed  that the amount of  energy  utilized in AI model training equaled 626,000 pounds of carbon dioxide. How so? Contemporary AI isn’t just run on a personal laptop or simple server. Rather, deep neural networks are deployed on diverse arrays of specialized hardware platforms. The level of energy consumption required to power such AI technologies is approximately five times the lifetime  carbon emissions  from an average American car, including its manufacturing.  Related:  This AI food truck could bring fresh produce directly to you Moreover, both  Analytics Insight  and  Kepler Lounge  warned that Google’s AlphaGo Zero — the  AI  that plays the game of Go against itself to self-learn — generated a massive 96 tons of  carbon dioxide  over 40 days of research training. That amount of carbon dioxide equals 1,000 hours of air travel as well as the annual  carbon footprint  of 23 American homes! The takeaway then? Numbers like these would make AI model deployment both unfeasible and unsustainable over time. MIT’s research team has devised a groundbreaking automated AI system, termed a once-for-all (OFA) network, described in  their paper here . This AI system — the OFA network — minimizes  energy consumption  by “decoupling training and search, to reduce the cost.” The OFA network was constructed based on automatic machine learning (AutoML) advancements.  Essentially, the OFA network functions as a ‘mother’ network to numerous subnetworks. As the ‘mother’ network, it feeds its knowledge and past experiences to all the subnetworks, training them to operate independently without the need for further retraining. This is unlike previous AI technology  that had to “repeat the network design process and retrain the designed network from scratch for each case. Their total cost gr[ew] linearly … as the number of deployment scenarios increase[d], which … result[ed] in excessive energy consumption and  CO2  emission.” In other words, with the OFA network in use, there is little need for additional retraining of subnetworks. This efficiency decreases costs, curtails carbon emissions and improves  sustainability . Assistant Professor Song Han, of MIT’s Department of Electrical Engineering and Computer Science, was the project’s lead researcher. He shared that, “Searching efficient neural network architectures has until now had a huge carbon footprint. But we reduced that footprint by orders of magnitude with these new methods.” Also of particular interest was Chuang Gan, co-author of the MIT research paper, who added, “The model is really compact. I am very excited to see OFA can keep pushing the boundary of efficient deep learning on edge devices.” Being compact means AI can progress towards miniaturization. That could spell next-generation advantages in green operations that improve environmental impact. + MIT News Images via Pexels and Pixabay

Corporate reporting on sustainability has grown more than fivefold in the past 10 years. Roughly 20 percent of S&P 500 companies published a sustainability report in 2011. In 2018, that number rose to 86 percent.
