Pollution: The Latest Architecture and News

An Intermittent Breath of Fresh Air: Declining Emissions in Cities Soon on the Rise After Coronavirus

From Wuhan to New York, the epicenter of the coronavirus is moving from east to west and leaving a staggering number of corpses behind. We read of alarming reports, contradictory news, and reminded every day that we live in unprecedented and difficult times. One good news, however: emissions in cities are on the decline, and nature is running its regenerative course. But how long will this last?

30 Plans, Sections and Details for Sustainable Projects

The dramatic improvement in recent decades in our understanding of sustainable design has shown that designing sustainably doesn't have to be a compromise—it can instead be a benefit. When done correctly, sustainable design results in higher-performing, healthier buildings which contribute to their inhabitants' physical and mental well-being.

The benefits of incorporating vegetation in façades and in roofs, as well as materials and construction systems that take energy use and pollution into account, demonstrate that sustainable design has the potential to create buildings that improve living conditions and respect the natural environment.

Below we have compiled 30 plans, sections and construction details of projects that stand out for their approach to sustainability.

"Plastic Island" Imagines the Possibilities of Reusing Oceanic Waste in Architecture

With rising sea levels and incessant consumption of plastic, the state of the earth's oceans is rapidly deteriorating. Instead of discarding or burning this plastic, architects Erik Goksøyr and Emily-Claire Goksøyr questioned whether any architectural potential exists in this neglected material. By conducting an extensive material study, the duo designed three prototypes to postulate this theory. 

Though starting out as a humble thesis, this project is being actualized under the organization, Out of Ocean. From the shores of the Koster Islands in Sweden, plastic samples were collected and studied for their various material performance in areas such as color, texture, light, and translucency.

World's Largest Air Purifier Completes Successful Trial Run in Xi'an, China

A 100-meter-tall air purification tower in Xi’an, China – believed to be the world’s largest air purifier – has significantly improved city air quality, results from its preliminary run suggest.

According to researchers from the Institute of Earth Environment at the Chinese Academy of Sciences, the tower has managed to produce more than 10 million cubic metres (353 million cubic feet) of clean air per day since it was launched a few months ago. In the 10-square-kilometer (3.86-square-mile) observed area of the city, smog ratings have been reduced to moderate levels even on severely polluted days, an improvement over the city’s previous hazardous conditions.

Massive River Development Plan Hopes to Rejuvenate India's Relationship to the Ganges

Delhi-based firm Morphogenesis has recently unveiled a proposal for a project that will rehabilitate and develop the ghats (a flight of steps leading down to a river) and crematoriums along a 210-kilometer stretch of the Ganges, India’s longest river. The project, titled “A River in Need,” is part of the larger National Mission of Clean Ganga (NMCG), an undertaking of the Indian Government’s Ministry of Water Resources which was formed in 2011 with twin objectives: to ensure effective abatement of the river’s pollution and to conserve and rejuvenate it.

How Rebuilding Britain’s Houses of Parliament Helped Create Clean Air Laws

MIT has published new research revealing how the reconstruction of the British Houses of Parliament paved the way for legislation to tackle air pollution in Victorian London. Through original archival work into the 1840-1870 reconstruction, MIT architectural historian Timothy Hyde has revealed that work on the Parliament building was so hindered by air pollution that the British government ordered an inquiry into the effects of the atmosphere on new buildings.

RMIT Researchers Develop a Lighter, Better Brick Made With Cigarette Butts

One man’s trash is another man’s building material. Researchers from the Royal Melbourne Institute of Technology (commonly known as RMIT University) have developed a technique for making bricks out of one of the world’s most stubborn forms of pollution: discarded cigarette butts. Led by Dr. Abbas Mohajerani, the team discovered that manufacturing fired-clay bricks with as little as 1 percent cigarette butt content could completely offset annual worldwide cigarette production, while also producing a lighter, more efficient brick.

This Innovative Brick Sucks Pollution From the Air Like a Vacuum Cleaner

These days air pollution in some cities is a big problem, and as a result, buildings that help alleviate that problem are all the rage. In recent years though, designers have started to move beyond simply reducing a building's emissions and started to work with techniques that actually remove pollutants from the air, through systems such as Nemesi's "photocatalytic" facade for the Italy Pavilion at the 2015 Milan Expo which captures and reacts with pollution in the presence of light.

However, in most cases these new technologies have been chemical, only affecting the air that physically comes into contact with them. What if buildings could take a more active role in pulling in pollutants from the sky? What if they could work a little more like a vacuum cleaner? This was exactly the inspiration behind the Breathe Brick developed by Carmen Trudell, an assistant professor at Cal Poly San Luis Obispo's school of architecture and founder of Both Landscape and Architecture.

Reconfiguring Urban Spaces To Compensate For "Poisonous" Air

In an article for The Guardian, Oliver Wainwright steps "inside Beijing's apocalypse": the poisonous, polluted atmosphere that often clings to the Chinese capital. He explores ways in which those who live in this metropolis have started to redefine the spaces they frequent and the ways in which they live. Schools, he notes, are now building inflatable domes over play areas in order to "simulate a normal environment." The dangers were made clear when "this year’s Beijing marathon [...] saw many drop out when their face-mask filters turned a shade of grey after just a few kilometres." Now, in an attempt to improve the living conditions in the city, ecologists and environmental scientists are proposing new methods to filter the air en masse. Read about some of the methods here.

The Solution To Pollution Is...The Rooftops?

The potential solution to smog and pollution may be hovering right over our heads, now that Students at the University of California - Riverside have designed a pollution reducing rooftop tile. According to their calculations, cladding one million rooftops with the tiles could remove 21 tons of nitrogen oxides -- daily. Currently the Los Angeles area spits out 500 tons of nitrogen oxides a day, so the tiles are just one piece of the puzzle in reducing pollution - however the students are imagining their nitrogen-oxide-eating Titanium Dioxide compound in exterior paints, concrete and more. To see all the possibilities, read the full article here.
