Can this be a big deal yet?
How will driverless cars change our cities?
-Cities will greatly expand, again
-Buildings and parking will be uncoupled, freeing up valuable land
Change is coming"
These vegetated surfaces don’t just look pretty. They have other benefits as well, including cooling city blocks, reducing loud noises, and improving a building’s energy efficiency.What’s more, a recent modeling study shows that green walls can potentially reduce large amounts of air pollution in what’s called a “street canyon,” or the corridor between tall buildings.
For the study, Thomas Pugh, a biogeochemist at the Karlsruhe Institute of Technology in Germany, and his colleagues created a computer model of a green wall with generic vegetation in a Western European city. Then they recorded chemical reactions based on a variety of factors, such as wind speed and building placement.
The simulation revealed a clear pattern: A green wall in a street canyon trapped or absorbed large amounts of nitrogen dioxide and particulate matter—both pollutants harmful to people, said Pugh. Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.
That’s why the green-wall study is “putting forward an alternative solution that might allow [governments] to improve air quality in these problem hot spots,” he said.Compared with reducing emissions from cars, little attention has been focused on how to trap or take up more of the pollutants, added Pugh, whose study was published last year in the journal Environmental Science & Technology.

Nigeria’s Cost & Energy-Efficient Floating Schools (by NLÉ)
The Makoko Floating School is an ambitious project that is currently under construction in the water community of Makoko in Lagos, Nigeria by NLÉ, a collaborative agency whose mission is to provide architectural change for developing cities. The project seeks to create floating buildings that are designed to serve as educational classrooms for neighborhood children.
The three-story architectural structure, built as a triangular prism, is intended to float on water with a base made of 256 plastic drums. The floating construct is built with locally sourced wood, electrically powered with solar panels, and designed to house about 100 students.
While this first generation of floating buildings is being designated solely as educational center, the project is opening a new chapter in architectural design that can be applied to a variety of facilities for poor communities like Makoko to urbanize efficiently. Because of the project’s green initiatives, each building is more affordable and cost-effective. Additionally, they accommodate for the climate changes that are resulting in the rise of sea levels.
America’s prairies are shrinking. Spurred on by the rush for biofuels, farmers are digging up grasslands in the northern Plains to plant crops at the quickest pace since the 1930s. While…
