On the impact of newer buildings on urban air pollution

2024-10-25T17:47:00-04:00

In hermetically sealed buildings, less fresh air gets in. [...] Eventually, this polluted indoor air – which is making more than a third of the planet sick – is expelled into the surrounding environment. This raises the question of how buildings pollute the air around them, what pollutants they produce, and whether this expelled air is sufficiently diluted once outdoors.

As the article mentions, the World Health Organization had previously pointed to a "lack of monitoring of air pollution levels, sources and consequences on public health" as a present danger for cities.

To fix it, authors César Martín-Gómez and Arturo H. Ariño of the Universidad de Navarra say: "A detailed understanding of how buildings contribute to pollution in cities is essential. This will give public authorities, decision-makers and managers the tools to establish strategies to, for example, minimise pollution through devices similar to the catalytic converters required on all combustion-powered vehicles. Eventually, we may even be able to recover useful components of domestic air, such as waste methane, which could be redirected to energy generation."

New York releases city’s first study on environmental justice

2024-04-09T11:41:00-04:00

The New York City Mayor’s Office of Climate and Environmental Justice has released the city’s first report into environmental justice issues.

Titled 'EJNYC: A Study of Environmental Justice Issues in New York City,' the study analyzes environmental hazards ranging from toxin exposure and summer heat vulnerability to flood risks and transit access.

Curators and designers of the U.S. Pavilion will call attention to worldwide plastic dependency at the 2023 Venice Architecture Biennale

2023-02-16T19:00:00-05:00

The U.S. Pavilion at the 18th Venice Architecture Biennale, which opens in May, will feature an examination of worldwide plastic dependency through the work of five artists and designers who will deliver site-specific commissions as part of the overall exhibition curated by Lesley Lokko, founder and director of the African Futures Institute.

SPACES' Executive Director Tizziana Baldenebro and Museum of Contemporary Art Cleveland curator Lauren Leving were selected to co-organize Everlasting Plastics, which will be on display as part of the Pavilion from May 20 – November 26, 2023.

Baldenebro explained, "Inherent to art and architecture is the aesthetic and materiality of form. Everlasting Plastics bridges this divide by drawing on the power of looking to serve as an entry point for reconsidering our relationships to material worlds."

"As the climate crisis becomes a tangible reality, our da...

New York to ban construction of schools near highways

2022-07-12T09:00:00-04:00

The New York State Assembly and Senate have passed a bill barring the construction of schools within 500 feet of a highway. The Schools Impact by Gross Highways Act (or SIGH Act) was written to protect school-age children from air pollution.

Under the bill, which will also apply to New York City, the New York Commissioner of Education will only be allowed to approve plans for a new school within 500 feet of a highway if they determine that space is so limited that no other site would be available.

Archinect Feature: Smog City: The Fight Against Urban Air Pollution

According to a recent analysis by the New York Civil Liberties Union (NYCLU), approximately one-third of New York’s students attend a school within 500 feet of a road whose daily volume exceeds 30,000 cars. Approximately 80% of these students are students of color, and 66% are low-income.

Amazon's latest warehouse battle has San Francisco lawmakers pushing for a moratorium on similar developments

2022-02-16T13:47:00-05:00

The second most valuable company in the world, Amazon has been gobbling up space throughout the southeast corner of the city, taking advantage of zoning meant to preserve blue-collar jobs in a market in which housing and office space have typically generated higher revenues.

Amazon bought a 510,000-square-foot former sanitation motor pool parcel in the Showplace Square section of the city for $200 million in December of 2020. It has since proposed an expansion of the site’s footprint into an over 725,000-square-foot distribution hub for 400 workers that neighboring tenants, including the diffuse California College of the Arts, say will create a “pedestrian nightmare” of around 2,900 vehicle trips a day.

Now, as a result of the company’s proposal, San Francisco Supervisor Shamann Walton is seeking legislation that would place an 18-month moratorium on any new parcel delivery services operating in the city. It has already picked up backing from the local Teamsters and UFCW unions. The legislative effort, which the paper sees as another flashpoint in the “war between organized labor and Amazon,” is also backed by more environmentally-minded Prothero Hill and Dogpatch inhabitants, who say the company “has the neighborhoods surrounded” with similar developme...

Amazon warehouses are wreaking havoc in California’s Inland Empire

2021-11-22T19:18:00-05:00

In California’s Inland Empire, dozens of mega-warehouses for Amazon, UPS and other companies are choking the cities with traffic and air pollution. Some argue that the jobs warehouses provide aren’t worth the cost, while others say it’s online shopping that’s the real problem.

Despite the boiler-plate promise of adding jobs to the community, warehouse-laden tracts have been dumping an increasing amount of pollutants into the atmosphere in the form of increased truck and air cargo traffic and propelled in part by a sharp rise in online shopping. Amazon opened its first fulfillment center in San Bernadino in 2012. Today, the company operates more than 30 in the area alone.

Southern California's Inland Empire is one of the most polluted regions in America. One study from the University of California, Riverside revealed an 11% increase in Covid-19 deaths related to the number of particulates in the air. Around 85% of the population that lives within half a mile from a warehouse identify as people of color.

“We’re dealing with smoggy summers that are getting worse and worse,” one Riverside resident told The Guardian in April. “We’re sick of getting alerts that say avoid being outside because of dirty air. This is not normal.”

Superfund sites sit idle under President Trump

2020-01-08T18:21:00-05:00

The Trump administration has built up the biggest backlog of unfunded toxic Superfund clean-up projects in at least 15 years, nearly triple the number that were stalled for lack of money in the Obama era, according to 2019 figures quietly released by the Environmental Protection Agency over the winter holidays. The accumulation of Superfund projects that are ready to go except for money comes as the Trump administration routinely proposes funding cuts for Superfund and for the EPA in general.

Under the current presidential administration, funding earmarked for cleaning up superfund sites has slowed to a trickle. According to an Associated Press report, the number of unfunded projects has ballooned from 12 in 2016, President Barack Obama's last year in office, to 34 this year.

Sites that need cleaning up include abandoned gold, lead and copper mines, according to the report, as well as lead contamination leftover from industrial uses at sites and pollution resulting from petrochemical manufacturing operations. In all, unfunded superfund clean-up sites exist in 17 states and Puerto Rico; President Donald Trump has repeatedly pushed to substantially reduce funding appropriated for both the Environmental Protection Agency and the Superfund program it oversees.

As California's wildfires become increasingly urban, concerns over airborne health risks grow 'worrisome'

2019-11-07T15:31:00-05:00

The samples he collects will help scientists better understand how the massive increase in seasonal wildfires burning through residential areas might be affecting our health. Where smoke once contained the remnants of only biomass (trees and other organic matter), fires are now burning up homes—structures that contain thousands of synthetic chemicals, paints, plastics, and metals that smolder and combust into tiny particles.

After years of improvement, air pollution in the U.S. is getting worse again

2019-10-24T14:09:00-04:00

Air pollution worsened in the United States in 2017 and 2018, new data shows, a reversal after years of sustained improvement with significant implications for public health. In 2018 alone, eroding air quality was linked to nearly 10,000 additional deaths in the U.S. relative to the 2016 benchmark, the year in which small-particle pollution reached a two-decade low, according to researchers at Carnegie Mellon University.

The Washington Post reports that "concentrations of the pollutant have risen about 5.5 percent since 2016," and points out several contributing factors that the Carnegie Mellon study identified: increased natural gas use and vehicle traffic, risen severity and frequency of wildfires, and the rollback of regulatory enforcement of the Clean Air Act in recent years.

"The health implications of this increase in [annual average fine particulate matter] PM2.5 between 2016 and 2018 are significant," explains the research paper. "The increase was associated with 9,700 additional premature deaths in 2018. At conventional valuations, these deaths represent damages of $89 billion."

Smoke from burning Amazon rainforest drops São Paulo into sudden darkness

2019-08-20T19:29:00-04:00

In the height of daytime, the sky suddenly blackened, and day became night in Sao Paulo. Sure, smog is bad in the Western Hemisphere’s largest city, where traffic jams can stretch for dozens of miles. But not this bad. What was going on? Was the end near?

A combination of meteorological events paired with smoke that had traveled hundreds of miles from intense forest fires in remote parts of the Amazon caused a period of sudden midday darkness in the most populous city in the Western Hemisphere on Monday, reports The Washington Post.

Meanwhile on Twitter, #PrayforAmazonia emerged as a trending hashtag, channeling the global outrage over the lack of media coverage and political action towards the vast forest fires which have been raging in the drought-stricken Amazon rainforest region of Brazil for more than two weeks now.

Fires are burning across central South America. Yesterday #NOAA20's OMPS instrument detected the aerosol index - an index that detects the presence of particles like soot and dust in the atmosphere - in the vicinity of the fires. This can help inform air quality forecasts. https://t.co/lCMwTqWxtA

How much pollution does cement really produce? Is there a cleaner solution?

2019-06-28T19:06:00-04:00

Cement is everywhere, but few notice the impact it has on the environment. A standard building material used everywhere, it is often confused with concrete. Cement is a key component in making concrete. By burning limestone at extremely high temperatures, this process turns the stone into a fine powder that's then mixed with clay and other minerals. This powder material, called clinker, is mixed together with other materials to create concrete. Despite its inexpensive and readily available supply, cement production is responsible for high levels of carbon dioxide emissions surpassing the emissions produced from trucks.

Mexico City deploys giant murals to clean its polluted air

2019-05-08T14:18:00-04:00

A colourful mural of a 35m-tall tree in Mexico City is one of three environmentally friendly new public works made using Airlite paint, which purifies polluted air in a process similar to photosynthesis. [...] the mural aims to increase oxygen levels in one of the western hemisphere’s most polluted cities, where ozone concentration levels remain high despite government regulations on fuel and cars.

"Airlite paint chemically reacts with pollutants in the air, turning them into inert compounds," reports The Art Newspaper. "The roughly 1,000 sq. m mural should neutralise the same amount of pollution created by around 60,000 vehicles a year."

The artists responsible for painting the mural on Reforma Avenue (pictured above) are members of the Spanish art collective Boa Mistura.

For the 19th time, Los Angeles takes the crown as the smoggiest city in the U.S.

2019-05-01T19:42:00-04:00

For 20 years, the American Lung Association has gathered and analyzed data from official air quality monitors creating its annual "State of the Air" report. It's been reported by the association that more than four in ten people currently live in areas where pollution levels are too dangerous to breathe. Now several factors contribute to such poor air quality; however, during the 20 years these reports have been conducted, Los Angeles has been ranked as the city with the most polluted air quality by ozone measurements.

Sadly, the city's air quality has gotten worse since last year's State of the Air report. The data gathered analyze ozone layers in the city. The San Bernardino and Riverside counties are also included with Los Angeles' data report which affects the city's ranking tremendously. Many may view smog as an obstruction from Los Angeles' cityscape, however, the long-lasting effects of poor air quality can cause severe damage like lung cancer with a higher risk for early de...

Investigating the hidden air pollution in our everyday indoor spaces

2019-04-08T16:07:00-04:00

House Observations of Microbial and Environmental Chemistry—was the world’s first large-scale collaborative investigation into the chemistry of indoor air. [...] The experiment’s early results are just now emerging, and they seem to show that the combined emissions of humans and their daily activities—cooking, cleaning, metabolizing—are more interesting, and potentially more lethal, than anyone had imagined.

In this New Yorker piece, writer Nicola Twilley observes one of the experiments of HOMEChem, who investigates the atmospheric chemistry of our indoor environments and how everyday activities can greatly affect its air quality.

“Dozens of the chemicals measured by the HOMEchem team are known to be harmful, and, as every scientist I spoke with mentioned, we spend almost all our time indoors, breathing them. Nonetheless, it is outdoor air-pollution levels that have been firmly linked to public health,” Twilley writes in the article.

What You Don’t See

2018-09-18T19:06:00-04:00

Follow the intricate supply chains of architecture and you’ll find not just product manufacturers but also environmental polluters. Keep going and you’ll find as well the elusive networks of political influence that are underwritten by the billion-dollar construction industry.

In "What You Don't See," Brent Sturlaugson examines the supply chains of architecture to make the case that designers must expand their frameworks of action and responsibility for thinking about sustainability.

Unraveling the networks of materials, energy, power, and money that must be activated to produce a piece of plywood, Sturlaugson argues that "any full accounting of environmental, economic, or social sustainability has got to consider not merely individual buildings and sites but also the intricate product and energy supply chains that are crucial to their construction."

Notre Dame is falling apart and relying on US donations for major repairs

2018-08-15T14:21:00-04:00

One of Europe’s most visited sites, with about 12 million tourists a year, is in dire need of repairs. Centuries of weather have worn away at the stone. The fumes from decades of gridlock have only worsened the damage. “Pollution is the biggest culprit,” says Philippe Villeneuve, architect in chief of historic monuments in France. “We need to replace the ruined stones. We need to replace the joints with traditional materials. This is going to be extensive.”

Notre Dame faces major repairs as the historic Cathedral's structure decays due largely to pollution. Funding for the repairs needed were difficult to raise as the cathedral is owned by the French government, yet their arrangement allows the Catholic archdiocese of Paris to use it for free. Both claimed the other responsible for raising funds, however the archdiocese stepped up creating Friends of Notre Dam last year.

The organization allows US citizens to make tax deductible contributions to the renovation of this historic landmark. Friends of Notre Dame hope to raise $114 million within the next five to 10 years.

India proposes to fight pollution after Supreme Court considers demolition of deteriorating Taj Mahal

2018-07-30T14:17:00-04:00

India has proposed a ban on plastics, polluting factories and construction around its 17th-century monument to love, the Taj Mahal, a government document showed, in a bid to stave off pollution that is turning the structure yellow and green. In a draft document submitted to the Supreme Court on Tuesday, authorities in Uttar Pradesh said they would ban all plastics, switch to electric and hydrogen vehicles, and boost the green cover within the precincts of the Taj, to fight pollution.

"The document was submitted after the justices, in a fit of anger during a hearing two weeks ago, demanded that authorities either restore the structure or tear it down," Reuters reports. "One of the seven wonders of the world, the Taj Mahal is flanked by a garbage-strewn river and is often enveloped by dust and smog from belching smokestacks and vehicles."

India's Supreme Court again weighs in on discolored Taj Mahal: shut it down, demolish it, or restore it

2018-07-16T15:50:00-04:00

The Taj Mahal in Agra could be closed unless the Indian government steps in and saves the neglected landmark, says India’s Supreme Court. “Either we shut down the Taj or demolish it or you restore it,” the two-judge committee told state officials last week. [...] The Supreme Court says that it will monitor the situation on a day-to-day basis from 31 July.

Frustrated with the slow response from officials in charge of restoring the deteriorating Taj Mahal, India's highest court demanded swift action to stop the ongoing discoloration of the iconic Unesco World Heritage site caused by pollution and millions of tiny insects, saying: "We want you to give us an action plan of what you propose to do. We will hear it and finally dispose it. If it has to be shut down, let it be shut."

The Taj Mahal went from white to yellow and now greenish

2018-05-10T19:08:00-04:00

India’s Supreme Court on Wednesday faulted the country’s archaeological conservation body for failing to protect the Taj Mahal from discoloration, dirty feet and green slime emitted by millions of mosquito-like insects. Since 2015, the body, the Archaeological Survey of India, has overseen a restoration project at the Taj Mahal, with workers scaling scaffolding to remove grime from the 17th-century tomb [...].

After decades of slowly turning dull and yellowish from smog and pollution, the Taj Mahal's formerly white facade has now taken on an unattractive green discoloration. Archaeological experts suspect swarms of tiny bugs to be the perpetrators, but India's highest court isn't pleased with the slow pace of cleanup of what is arguably India's most well know architectural landmark.

China builds "world's biggest air purifier" to battle air pollution

2018-01-17T13:36:00-05:00

An experimental tower over 100 metres (328 feet) high in northern China – dubbed the world’s biggest air purifier by its operators – has brought a noticeable improvement in air quality, according to the scientist leading the project, as authorities seek ways to tackle the nation’s chronic smog problem. [...] The head of the research, Cao Junji, said improvements in air quality had been observed over an area of 10 square kilometres (3.86 square miles) in the city over the past few months [...].

Now that the experimental smog-eating tower is up and running in the city of Xian, authorities are hoping to build much bigger, scaled-up versions in other Chinese cities soon: "A full-sized tower would reach 500 metres (1,640 feet) high with a diameter of 200 metres (656 feet)," the South China Morning Post writes.

A smog-cleaning bike, a kite-charging dike: Studio Roosegaarde's creative design solutions to infrastructural challenges

2017-08-22T15:03:00-04:00

In the unofficial category of "Creative Pollution Solutions," the Dutch firm Studio Roosegaarde is angling to be the winner: the firm has several projects that introduce innovative solutions to existing infrastructural challenges. First up, in partnership with bike-sharing firm OFO, the studio has announced to develop a bicycle that "inhales" smog and then releases purified air by virute of pedaling.

The project, which was initially announced at a TED forum, has now advanced to the first stage of design. The bikes, which release clean air around each cyclist as they are pedaled, are not only environmentally friendly but culturally attuned: Daan Roosegaarde wanted to reference the iconicity of the bicycle in China while simultaneously improving air quality.

In addition to the bicycles, Studio Roosegaarde has also undertaken the redevelopment of the Icoon Afsluitdijk. As the architects explain: "It is the government-scale landscape innovation project on the legendary Dutch dike, whic...

Barcelona's bold new plan to get cars off the road

2016-05-18T13:09:00-04:00

In the latest attempt from a big city to move away from car hegemony, Barcelona has ambitious plans. Currently faced with excessive pollution and noise levels, the city has come up with a new mobility plan to reduce traffic by 21%. And it comes with something extra: freeing up nearly 60% of streets currently used by cars to turn them into so-called “citizen spaces”.

"The plan is based around the idea of superilles (superblocks) – mini neighbourhoods around which traffic will flow, and in which spaces will be repurposed to “fill our city with life”, as its tagline says."

A precedent for Barcelona's superblocks was actually instituted in the city back in the late 19th century when Ildefons Cerdà planned Eixample, a district intended to free up the crowded medieval neighborhoods of the old city. With their famous beveled corners, Cerdà's large residential blocks were intended to serve as lungs for the city, with interior courtyards to provide greenery on a regular and frequent basis.

But urban development laid waste to Cerdà's carefully-laid plans. Today, the city loses about 3,500 citizens each year to air pollution.

The bold new plan comprises a series of interventions to create "superblocks" from nine of Cerdà's smaller blocks. The initiative starts with restricting vehicular traffic to primarily the perimeter streets.

City officials hope that by i...

Billions exposed to dangerous air as pollution grows at alarming rates around the world

2016-05-12T12:42:00-04:00

Outdoor air pollution has grown 8% globally in the past five years, with billions of people around the world now exposed to dangerous air, according to new data from more than 3,000 cities compiled by the World Health Organisation (WHO). While all regions are affected, fast-growing cities in the Middle East, south-east Asia and the western Pacific are the most impacted with many showing pollution levels at five to 10 times above WHO recommended levels.

According to the WHO data, the most polluted city in the world is Onitsha, a booming port city on the coast of Nigeria. With almost 600 micrograms per cubic meter, the city has around 30 times the recommended level of PM10 particles (the larger, but still dangerous, air pollutant particles).

These are the most-polluted cities in the US

2016-04-20T18:19:00-04:00

Residents of just four American metropolitan areas have had regular access to healthy air in recent years. Those four places — Burlington-South Burlington, Vt.; Honolulu; Elmira-Corning, N.Y.; and Salinas, Calif. — had the pleasure of breathing air consistently free of unhealthy ozone, short-term particle and year-round particle pollution from 2012 to 2014,according to a new national air quality report card from the American Lung Association. The air everywhere else was less consistently clean.

Actually, air quality has significantly improved in American cities since the passing of the 1970 Clean Air Act and subsequent legislation. This year marked the lowest particle pollution levels in 16 years for all but four of the top 20 most-polluted cities.

Still, things remain pretty grim: more than half of Americans are breathing unhealthful levels of polluted air today.

Here are the most-polluted cities (by year-round particle pollution):

Bakersfield, Calif.
Visalia-Porterville-Hanford, Calif.
Fresno-Madera, Calif.
Los Angeles-Long Beach, Calif.
El Centro, Calif.
(tied) Modesto-Merced, Calif.
(tied) San Jose-San Francisco-Oakland, Calif.
Pittsburgh-New Castle-Weirton, Pa.-Ohio-W. Va.
Harrisburg-York-Lebanon, Pa.

How one architect is working to fix Mexico City's faulty water supply infrastructure

2016-03-23T18:42:00-04:00

'Mexico City’s water system goes against its own functional essence. The city is dehydrating itself. We’re mixing our water with poisonous waste and then pumping it out through a complex network of pipes. Just like what happens when a human is dehydrated, Mexico City has diarrhea.' — Elias Cattan

"In a mega-metropolis with a deep history of corrupt leaders and state-sanctioned misinformation, [architect Elias Cattan of Taller 13] believes awareness is the first step. That’s why he’s part of a growing movement of environmental scientists, activists, designers and engineers determined to redesign Mexico City’s water supply management while educating its 9 million residents in the process."

Smog-choked Beijing plans "ventilation corridors" to provide much-needed fresh air

2016-03-03T14:14:00-05:00

Beijing is stepping up measures to fight against smog and pollution by building a web of ventilation corridors as one of its plans to combat climate issues, according to municipal authorities. “Ventilation corridors can improve wind flow through a city so that wind can blow away heat and pollutants, relieving urban heat island effect and air pollution,” Wang Fei, deputy head of Beijing’s urban planning committee, told Xinhua News Agency.

The planned "ventilation corridors" would range from less than 80 meters to more than 500 meters wide and – hopefully – do what their name suggests, providing a conduit for wind to blow away pollutants like particulate matter.

Five major corridors are planned for the Chinese capital, running primarily from the northern suburbs to the south of the city. One will cross Beijing's central axis, running from Taiping Suburban park down through the Olympic Park and the Temple of Heaven before finally intersecting with the Beijing-Shanghai Highway.

Ventilation corridors have already been carved out of other Chinese cities such as Shanghai, Nanjing, and Wuhan. In Wuhan, planners believe that the corridors have lowered temperatures by as much as 1 to 2 degrees Celsius (urban temperatures and pollution levels correlate).

Beijing has struggled with its pollution problem for many years now, with only marginal improvements following the closure of the city's worst polluting factories. China has also...
