Design as Repair: How Architecture Is Advancing Environmental Justice

Olivia Poston — Wed, 03 Jun 2026 07:30:00 +0000

Environmental justice confronts a simple but uncomfortable truth: the benefits and burdens of the environment are not shared equally. Marginalized communities bear a disproportionate share of polluted air, unsafe water, toxic land uses, extreme heat, and the accelerating risks of climate change in cities around the world. These are the consequential products of decades of policy decisions, investment patterns, exclusionary planning practices, and planning choices that have consistently favored certain communities over others.

Thermal Memory: How Climate Shapes Architectural Heritage

Ananya Nayak — Fri, 27 Feb 2026 05:00:00 +0000

On a hot afternoon in May, when the air over western India turns metallic with heat, no one remembers façade composition. They remember where the shade falls. They remember which corridor breathed. They remember the house that was cooler than the street. What stays in memory is comfort beyond the form. Repeated thermal preference stabilizes into spatial configuration, and over time, those configurations become building types.

How Cities Design Public Life in the Shade

Olivia Poston — Fri, 30 Jan 2026 05:00:00 +0000

Cities are warming at roughly twice the global rate, a trend accelerated by rapid urbanization. While rising temperatures are reshaping daily life worldwide, some towns and neighborhoods, often the most vulnerable and least resourced, are warming more than others. The reason comes down to the urban environment. Built infrastructure, such as roads, buildings, sidewalks, and public spaces, determines how heat moves through a city, where it accumulates, and how long it remains trapped. No matter the climate zone or geographical location, shade remains the most effective and immediate way to cool pedestrians and relieve the built environment.

Rethinking Urban Cooling: A Case for Low-Energy Radiant Technology

Eduardo Souza — Tue, 30 Sep 2025 07:30:00 +0000

When exposed to heat, the body activates several physiological mechanisms to maintain thermal homeostasis. However, these natural defenses are often overwhelmed in our modern cities. In an urban environment defined by heat-absorbing asphalt, concrete, and a lack of green spaces, these mechanisms become inefficient. If the surroundings are excessively hot, humid, or poorly ventilated—conditions amplified by the Urban Heat Island effect—the core body temperature begins to rise, and the risk of serious complications increases, ranging from cramps and exhaustion to potentially fatal heat strokes.

Cooling the City: How European Cities are Adapting to Extreme Heat

Reyyan Dogan — Thu, 03 Jul 2025 06:30:00 +0000

The summer of 2025 has brought extreme heat across Europe and beyond, with record-breaking temperatures and widespread climate-related impacts. Red alert warnings have been issued in France, Italy, and Spain as temperatures exceeded 46°C in parts of the Iberian Peninsula. These conditions have led to school closures, restrictions on outdoor work, and pressure on urban infrastructure, including power grids and public transport systems. The heatwave has simultaneously intensified wildfire risk across the Mediterranean. In western Turkey, ferocious wildfires near Izmir forced the evacuation of over 50,000 people as high winds and low humidity fueled rapidly spreading flames. In Spain's Catalonia region, two people died in a wildfire that raced across farmland and old structures in Torrefeta on July 1. Similar disasters have occurred in Greece, France, and Italy, with evacuations throughout southern Europe as widespread heat‑induced drought exacerbates fire season intensity.

Strategic Green Spaces: How to Make the Most of their Cooling Effects

Maria-Cristina Florian — Thu, 05 Jun 2025 04:00:00 +0000

Urban green spaces are considered one of the most appropriate and accessible ways to mitigate the effects of rising temperatures in urban environments. As the global climate warms, cities worldwide face more frequent and extreme heat waves, putting their citizens at risk. Many cities are employing strategies for reducing the impact of urban heat islands, which are generated when natural land cover is replaced with surfaces that absorb and retain heat, such as pavements and buildings. This raises the temperature by several degrees compared to the surroundings. Cities have their micro-climate, influenced by this phenomenon combined with a series of often overlooked factors. For a climate strategy to be efficient, all factors need to be taken into consideration.

How Can Cities Cool down Large Urban Car Parks?

Paul Yakubu — Fri, 23 Feb 2024 07:30:00 +0000

The urban heat island effect occurs when pavements, roads, and buildings absorb the sun's heat and radiate it back, causing the temperature to increase and preventing the city from cooling down. With the growing reliance on cars in cities, the number of urban car park spaces is also increasing to accommodate buildings. This has resulted in the conversion of large areas of pervious land covered with vegetation into impervious hard surfaces for more car parks. The use of materials like asphalt, combined with the lack of shade, reflective steel surfaces of parked cars, and loss of greenery in these extensive car parks, contributes to the amplification of high-temperature effects and extreme heat events, making urban spaces uncomfortable. This transformation is impacting the climate of car-dependent regions and calls for collaborative ideas and efforts to mitigate the negative effects of rising heat.
