Buro Happold and Dialog unveil new urban thermal comfort study for Toronto

2024-01-22T18:45:00-05:00

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 mitigate the growing number of extreme heat days it faces in a given year.

The study will go a long way in informing Toronto’s response to heat and climate, leading eventually to the creation and implementation of new comfort guidelines included as part of a broader Heat Relief Strategy that was debuted two years ago. Toronto's City Planning Division contracted Buro Happold and Dialog to lead the study based on the former’s extensive experience with similar plans for large metro areas such as New York, Los Angeles, and Minneapolis.

“These are significant new kinds of guidance that city leaders everywhere need to help protect their citizens and support public health in an era of rapid climate change,...

President Biden lays out workplace heat safety plan to protect workers

2023-07-31T17:06:00-04:00

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.

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, heat has become the number one cause of weather-related deaths in the U.S.

Biden directed the U.S. Department of Labor to issue hazard alerts notifying employers and employees about ways to stay protected from extreme heat. The Department will also increase its inspections of at-risk workplaces such as farms and construction sites and heighten its enforcement of heat safety violations. The Biden administration aims to invest $7 million to develop more accurate weather predictions and $152 million to improve drinking water infrastructure in California, C...

U.N. global chief heat officer warns of the acute dangers of rising temperatures in cities

2023-07-31T15:40:00-04:00

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.

Amid devastating wildfires and record-breaking numbers of heat-related casualties throughout the Mediterranean region, Spanish newspaper EL PAÍS sits down with Eleni Myrivili, chief heat officer of Athens (Europe's first such municipal appointment) and also global chief heat officer to U.N. Habitat, to learn which concrete design and policy strategies can improve urban live in cities and help protect especially the most vulnerable groups.

Myrivili isn't holding back harsh criticism when she comments on an example of public urban design she deems inadequate for today's challenges — Madrid's Puerta del Sol square — saying, "Today, It is criminal to build squares without shade or cooling elements, because they create higher temperatures in the city, put people’s lives at risk and keep people away from public space."

Speaking also to The Guardian recently, Myrivili remarked on the increasing challenges of heat in cities and the built environment: "People are just starting to realize th...

The ASLA Fund announces two winners for its Inaugural National Competitive Research Grants

2023-07-19T15:32:00-04:00

The American Society of Landscape Architects (ASLA) fund has just announced a pair of winners of its inaugural national competitive grants, offering a total of $25,000 to researchers working towards solutions to both climate change and the ongoing biodiversity crises in the United States.

"We help communities adapt to climate-driven extreme weather and support biodiversity,” ASLA CEO Torey Carter-Conneen explained at the announcement. “The infrastructure challenges in municipalities across the country are enormous —landscape architects bring transformative solutions.”

Planting trees could lead to fewer heat-related deaths in urban areas, according to a new study

2023-02-03T17:32:00-05:00

A new scientific study has shown the positive correlations between public health and tree planting in urban areas.

In a report published recently by The Lancet medical science journal, a team of European researchers shared data on mortality rates in 93 cities in the summer of 2015 that showed how premature deaths caused by urban heat islands can be mitigated through increased greening strategies.

The study found 6,700 premature deaths in that period related to the phenomenon. One-third of those deaths, according to the authors, could have been prevented by adding 30% more trees in the urban environments of each city. The data supports established notions that particularly low-income communities can benefit from resiliency measures, adding to a growing chorus of scholarship at a time when climate change is becoming a moribund issue for cities worldwide at an accelerated pace.

The ASLA calls on members to support new congressional funding for heat mitigation effort nationwide

2022-10-24T16:06:00-04:00

The American Society of Landscape Architects (ASLA) is now soliciting support for a new congressional effort aimed at bolstering heat mitigation strategies in vulnerable communities across the country.

The bill, formally titled H.R. 7534, was introduced by Democratic Arizona Congressman Ruben Gallego and would enhance the ability of landscape professionals to design solutions that will mitigate the effects of heat on urban areas across through the establishment of a new grant program to be administered by HUD and the EPA.

Project types that will be eligible for funding after the establishment of the new act include pavement cooling, shade structures, cooling centers, green roofs, drought-tolerant vegetation planting, and other techniques.
