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
Researchers at the University College London have put forth a new argument in favor of a simple solution to combating the issue of extreme heat in cities without air conditioning. The so-called “cool roof” method they found had the best mitigation performance metrics over others surveyed... View full entry
City Councilmember Lincoln Restler of Brooklyn, who confirmed the news with Gothamist on Wednesday, said he plans to introduce his bill during Thursday’s stated meeting. The bill is intended to mimic current local law requiring landlords to provide tenants with heat during the winter months by requiring them to ensure tenants can cool their homes to at least 78 degrees when it is 82 degrees or warmer during the summer, Restler said. — Gothamist
Councilmember Restler, who argues that the new legislation is tantamount to requiring heating in the winter, also told the New York Times it will "save lives as we reckon with the challenges of the climate crisis." Landlords would have a maximum of four years to comply with the mandate. The... 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
The City of Toronto recently completed a groundbreaking study of its ‘thermal comfort’ done by Buro Happold and Dialog. The work will provide valuable lessons to urban planners, developers, and other stakeholders as the country’s largest metropolitan area prepares a strategy to suitably... View full entry
President Joe Biden on Thursday announced plans to increase protections for workers facing extreme heat, as temperatures across the U.S. soar and large swaths of the country face heat advisories. — HR Dive
The President’s announcement comes as close to 40% of the U.S. population faces heat advisories, according to the National Weather Service. The country currently has no federal standards on workplace heat safety, and there has been no timeline for the finalization of one. As reported by HR Dive... View full entry
Rising temperatures and increasingly frequent heat waves driven by climate change are turning many Mediterranean cities into dangerous places, especially for vulnerable groups.
“We are not focusing enough on how extreme temperatures affect urban environments,” says Eleni Myrivili, who has spent years studying this issue in her hometown of Athens, which is one of the cities hardest hit by rising temperatures.

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...

“Underground climate change is a silent hazard,” he said. “The ground is deforming as a result of temperature variations, and no existing civil structure or infrastructure is designed to withstand these variations.” — NBC Chicago
NBC Chicago reports on research from Northwestern University Assistant Professor of Civil and Environmental Engineering Alessandro Rotta Loria and his findings on the effect of density and subterranean heat in the city’s downtown Loop, where temperatures have been shown to be... View full entry

Kargbo grew up to become a banker, but she has spent the last several years working in the administration of Freetown mayor Yvonne Aki-Sawyerr, a noted climate activist. Before becoming the city’s chief heat officer, she headed up the city’s sanitation department [...] Kargbo says her work is to keep climate change on the agenda, however many other things are tugging the world’s attention away. — Experience Magazine
A former aide to the noted climate activist Mayor of Freetown Yvonne Aki-Sawyerr, Eugenia Kargbo is one of five official Chief Heat Officers (CHOs) in the world.
