Corrugated facade patterns were shown to reduce surface temperature on structures by up to 3.1°C (5.6°F) in a new experiment from a team of researchers at Columbia University. Their research into a scalable FinWall model, first published this spring in Cell Reports Physical Science, provided... View full entry
Most often, homes with little or no air conditioning are occupied by low-income residents – often renters — and people of color, a 2022 Boston University analysis of 115 U.S. metro areas found.
That leaves them vulnerable as climate change makes heatwaves more frequent, more intense and longer lasting. Heat stress now kills more people globally each year than any other weather-related cause, according to the World Health Organization — and many of these deaths occur indoors.

New York, Los Angeles, and Austin are each currently mulling aggressive cooling laws that would levy huge fines against landlords who do not provide their tenants with efficient cooling systems, joining other states and cities in a burgeoning movement. As was reported last week, 2023 saw a 20%... View full entry
Future city dwellers could beat the heat with clothes made of a new fabric that keeps them cool. The textile, made of a plastic material and silver nanowires, is designed to stay cool in urban settings by taking advantage of a principle known as radiative cooling – the natural process by which objects radiate heat into space. — New Scientist
The material was designed by a team of researchers at the University of Chicago led by Po-Chun Hsu, an Assistant Professor of Molecular Engineering. They designed it to block more than half of the radiation from the buildings and the ground. As reported by New Scientist, the material emits heat in... View full entry
To combat the intense summer heat in France, a geothermal energy system will cool the athlete apartments in the Seine-Saint-Denis suburb. This technology utilizes natural resources and is expected to reduce carbon impact by 45 percent compared to traditional air conditioning systems. The system will maintain a temperature below 79 degrees Fahrenheit during the night, even in the event of a heatwave, according to Laurent Michaud, the director of the Olympic and Paralympic Villages. — Runner's World
The planned alternative system will distribute cold water from underground to cool through the floors of the apartments, which will later become home to more than 6,000 permanent residents after the more than 15,000 Olympic and Paralympics athletes vacate in September. The buildings all have green... View full entry
MIT researchers have published details of a new open-source forced-air evaporative cooling chamber. Described as being less expensive than refrigerated cold rooms, the chamber is intended to offer accessible cold storage for smallholder farmers, as well as significantly reduce post-harvest...

New York-based SHoP has completed work on the Uber Headquarters in San Francisco. The 423,000-square-foot project is divided into two buildings ranging between six and eleven stories, linked by two suspended walkways. Photo © Jason O'Rear Photo © Jason O'Rear The scheme’s star... View full entry
Scientists in the US have developed a paint significantly "whiter than the whitest paint currently available".
Tests carried out by researchers at Purdue University on their "ultra-white" paint showed it reflected more than 98% of sunlight.
That suggests, the scientists say, that it could help save energy and fight climate change.
— BBC
The paint's whiteness opens up a range of cooling features that, applied at an industrial scale, could limit the built environment's contributing effect to global warming and its dependency on traditional air conditioning. "If you were to use this paint to cover a roof area of about 1,000 square... View full entry
In the main axis of the new multimodal hub in the French city of Nice, for the first time in Europe, a large expanse of urban cooling paving is being installed. It corresponds to the areas of most intense pedestrian presence (bus stops, pavements, etc.) and represents an attempt to improve the... View full entry
Five years ago we reported on a device invented by a group of students at MIT. This device, originally called "Wristify", was a small bracelet designed to heat or cool the wearer to achieve customized comfort, regardless of the surrounding environment. Today, after a few years of R&D, and with... View full entry
The US expends more energy on air conditioning, for example, than the whole of Africa does on everything. Then again, it expends even more energy on hot water, which doesn’t get the same rap. The question then is not whether to condition climate, but how. As long ago as the 1940s the Egyptian architect Hassan Fathy demonstrated, with his village of New Gourna near Luxor, how traditional techniques of orientation, ventilation, screening and shading could be revived. — The Guardian
Rowan Moore dives into the history of air conditioning and how the development of this technology shaped architectural design over the years. Rather than condemn its use, Moore advocates for optimizing both old and new techniques for sustainable cooling with the current challenge to scale up for... View full entry
A new study by researchers at the University of Southern California found that replacing all lawns with drought-tolerant vegetation would have a net cooling effect of 0.2°C — but the science is less obvious than you might think. In fact, converting lawns has resulted in daytime warming of up... View full entry
The management at the Auschwitz-Birkenau State Museum has defended the installation of sprinkler showers at its entrance, after a visitor complained that the new facilities were a painful reminder of the gas chambers used to murder prisoners. — The Independent

The intent is to save energy by controlling the temperature of an individual person, rather than an entire building, a goal that anyone who's ever turned on a personal space heater in a frigid office building in July can get behind. The team just won $10,000 from MIT's Making And Designing Materials Engineering Competition, which the inventors will use to improve the prototype and the algorithms that automate the pulses. — popsci.com
Google’s new $700 million data centers in Taiwan will make ice at night, when electricity is significantly cheaper, and use it to cool the buildings during the day, reports Rich Miller at Data Center Knowledge. It’s called thermal storage, and it’s basically a battery, but for air conditioning. — grist.org
Mongolia is to launch one of the world's biggest ice-making experiments later this month in an attempt to combat the adverse affects of global warming and the urban heat island effect.
The geoengineering trial, that is being funded by the Ulan Bator government, aims to "store" freezing winter temperatures in a giant block of ice that will help to cool and water the city as it slowly melts during the summer.
