Living Wall

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.

Dowling Duncan and redesigning the American Dollar:

Why the size?
We have kept the width the same as the existing dollars. However we have changed the size of the note so that the one dollar is shorter and the 100 dollar is the longest. When stacked on top of each other it is easy to see how much money you have. It also makes it easier for the visually impaired to distinguish between notes.

Why a vertical format?
When we researched how notes are used we realized people tend to handle and deal with money vertically rather than horizontally. You tend to hold a wallet or purse vertically when searching for notes. The majority of people hand over notes vertically when making purchases. All machines accept notes vertically. Therefore a vertical note makes more sense.

Why different colors?
It’s one of the strongest ways graphically to distinguish one note from another.

Why these designs?
We wanted a concept behind the imagery so that the image directly relates to the value of each note. We also wanted the notes to be educational, not only for those living in America but visitors as well. Each note uses a black and white image depicting a particular aspect of American history and culture. They are then overprinted with informational graphics or a pattern relating to that particular image.

$1 – The first African American president
$5 – The five biggest native American tribes
$10 – The bill of rights, the first 10 amendments to the US Constitution
$20 – 20th Century America
$50 – The 50 States of America
$100 – The first 100 days of President Franklin Roosevelt. During this time he led the congress to pass more important legislations than most presidents pass in their entire term. This helped fight the economic crises at the time of the great depression. Ever since, every new president has been judged on how well they have done during the first 100 days of their term.

Love these.

This is cool.
