It might sound like a plot cooked up by a cartoon villain, but a city in southwestern China is aiming to launch into space an artificial moon that could replace streetlights by bathing the ground in a “dusk-like glow.”
[...] the satellite’s mirror-like exterior would reflect sunlight down to Earth, creating a glow about eight times brighter than the moon. The artificial moon, which he said would orbit about 500 kilometers above Earth, could save $174 million in electricity from streetlights.

The capital of China's Sichuan province, Chengdu, could have its own illumination satellite 'moon' up in the skies by 2020, according to the People's Daily. Light pollution, and its documented health effects on humans and nocturnal wildlife, doesn't seem to be much of a concern to the officials... View full entry
Shit, I Smoke! was created by Brazilian-born designer Marcelo Coelho and Paris-born app developer Amaury Martiny in just a week, after they read a study that analyzed air pollution and its equivalent to cigarette smoking. [...] Using the formula in [the study], [the app] uses live pollution data from hundreds of air quality stations in cities around the globe and converts the station’s PM2.5 number into the number of cigarettes being inhaled by a person in real time. — Citylab
“For both Coelho and Martiny, the app isn’t only a useful tool to inform users about their city’s air quality; it also makes this information more accessible and easier to comprehend.” View full entry
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...

Beijing will suspend construction of major public projects in the city this winter in an effort to improve the capital’s notorious air quality, official media said on Sunday, citing the municipal commission of housing and urban-rural development.
All construction of road and water projects, as well as demolition of housing, will be banned from Nov. 15 to March 15 within the city’s six major districts and surrounding suburbs, said the Xinhua report.

The American Medical Association (AMA) has just adopted an official policy statement about street lighting: cool it and dim it.
The statement, adopted unanimously at the AMA's annual meeting in Chicago on June 14, comes in response to the rise of new LED street lighting sweeping the country. An AMA committee issued guidelines on how communities can choose LED streetlights to "minimize potential harmful human health and environmental effects."

There are two basic issues at hand. First, new, "white" LED lighting, which have a color temperature of between 4000K and 5000K, can cause discomfort and glare. This is because the light is concentrate and has high blue content, which can cause severe glare and force pupillary constriction... View full entry
Sentinel Peak Resources, which took over the roughly 1.1-acre site in December, now believes that affordable housing is the “best beneficial use” for the land [...] Neighborhood leaders said they were interested in closing and re-purposing the site, but are awaiting more details. They stressed that regardless of any plans, they still want the city to pursue their concerns about violations at the site, which Sentinel Peak Resources has so far brushed off. — Los Angeles Times
According to the L.A. Times, “No official plan has been drafted and details are scant, but [L.A. City Council President Herb] Wesson said he was ‘unbelievably excited’ about the idea, arguing it could pave the way to convert other local drilling sites.”But converting the site — which is...

The wide-ranging efforts include improving indoor air quality and even increasing activity levels of building occupants. Allen and colleagues at the Harvard T.H. Chan School of Public Health have defined nine foundations for healthier buildings, such as better water quality, reducing noise, regulating temperature, and maximizing light. — National Geographic
As part of the Urban Expeditions series, Brian Howard explored some of the latest trends in green design, which go far beyond energy and water efficiency to issues of public health/wellness. View full entry
When the Government Hospital for the Insane opened in Anacostia in 1855, the asylum’s supervising physician, Charles Nichols, predicted that 50 percent of the mentally ill people treated there would make a full recovery. What made him so confident? The building. He’d designed it in accordance with the most cutting-edge theories of the day, which called for sunny, well-ventilated asylums in the countryside — the Washington Post
The "Architecture of an Asylum: St. Elizabeth's 1852-2017" is a new exhibit opening at the National Building Museum this weekend. It looks at past theories that contended that design could have a major and healing effect on mental illness. Fresh air was encouraged, as was scattering... View full entry

Birds fly in and out of the eight-storey "Green Office Building" in Shenzhen, China, because a third of its walls are completely open to the air. It's a clever natural design that enables the building to stay cool without air conditioners.
Across town, in a vast campus known as the "Low Carbon Park", mist is sprayed into the air to cool the streets down and remove dust.
