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.
The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.
While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.
The Global Award for Sustainable Architecture, created in 2006 by architect and scholar Jana Revedin, annually recognizes five architects—or offices—from around the world whose practices are grounded in the principles of sustainable development, participatory design, and a community-oriented approach. This recognition aligns with the global urgency surrounding today's pressing issues—the ecological and climate crises, as well as social, cultural, and economic challenges. Acknowledging architecture's critical role in shaping the built environment, the award seeks to highlight the work of creators who address these challenges with innovative and creative solutions.
In recent weeks, cities around the world have introduced new policies, recovery efforts, and infrastructure projects that reflect growing pressure to adapt to climate realities. From Southern Europe to South America and the United States, these urban updates address both immediate challenges and long-term shifts in how the built environment is governed, designed, and inhabited. Some initiatives focus on regulation, tightening building codes in fire-prone areas or reforming aging safety systems, while others spotlight large-scale investments tied to global events such as COP30 and the Venice Architecture Biennale. This edition of Architecture Now gathers a selection of city-led actions and collaborative efforts that point toward a more resilient, responsive future for architecture and urban life.
Germany's contribution to the 19th Venice Architecture Biennale 2025 will expose visitors physically and psychologically to the future urban climate: a STRESSTEST that makes the need for immediate action palpable. The exhibition takes a clear stance: climate change is an unstoppable reality, and the measures taken so far are inadequate. It presents a scenario in which climate change manifests globally through rising temperatures, extreme weather, and sea level rise, with its effects directly felt at a local level: urban spaces suffering from heat stress. Curators Nicola Borgmann, Elisabeth Endres, Gabriele G. Kiefer, and Daniele Santucci have designed an exhibition to highlight the impacts of global warming on urban life in an urgent call to action, emphasizing that this reality threatens urban social life, productivity, and the health and survival of citizens.
During a live presentation for the 19th International Architecture Exhibition, curator Carlo Ratti offered a glimpse into the programming of this year's edition. The 2025 Venice Architecture Biennale will include 66 National Pavilions, with 4 countries represented for the first time: the Republic of Azerbaijan, Sultanate of Oman, Qatar, and Togo. The exhibition, divided between the Giardini (26), at the Arsenale (22) and in the city center of Venice (15), explores the theme of "Intelligens. Natural. Artificial. Collective", gathering over 750 participants, including individuals and organizations forming interdisciplinary and multigenerational teams. According to the numbers released, this year's edition is shaping up to become the largest Architecture Biennale held in Venice.
Modernism emerged in the early 20th century as a revolutionary movement that rejected historical styles, prioritizing functionality, innovation, and rationality. Grounded in the promise of industrial progress, architects like Walter Gropius, Le Corbusier, and Ludwig Mies van der Rohe championed using new materials and construction methods, striving for a universal architectural language. Their work introduced radical ideas: open floor plans, expansive glazing for natural light, and pilotis that elevated structures, symbolizing a new architectural era. However, alongside its groundbreaking ideas, modernism's relationship with sustainability has sparked ongoing debates.
While modernist architects sought to address social and economic challenges through affordable housing and efficient design, their reliance on energy-intensive materials like concrete and steel created unintended environmental consequences. The large-scale industrialization celebrated by modernists often disregarded local climates and ecological systems, leading to inefficiencies. Yet, the principles of functionality and adaptability embedded in modernist architecture laid the groundwork for what we now recognize as sustainable practices. From Le Corbusier's rooftop gardens to Frank Lloyd Wright's integration of nature, the seeds of environmentally conscious design were undeniably present, albeit limited in their execution.
Devastating wildfires across Los Angelesa have resulted in widespread destruction, displacing thousands of residents, and necessitating a rapid and efficient rebuilding process. Two executive orders have been issued to expedite the rebuilding process, one by Los Angeles Mayor Karen Bass and another by California Governor Newsom, both intending to remove significant regulatory hurdles and expedite project approvals.
The Danish Architecture Center (DAC) will open its new exhibition, "Water is Coming" in October 2024, remaining open until March 12, 2025.

It acknowledges the reality of rising sea levels and extreme weather events, shifting the focus from mitigation to adaptation. The exhibition aims to foster a deeper understanding of our complex relationship with water, exploring its vital role as both a life-giving resource and a potential threat to human settlements.
In 2024, architecture continues to evolve in response to global challenges, with an increasing focus on sustainability, cultural context, and social responsibility. ArchDaily's interviews with leading architects, such as Kengo Kuma and Anne Lacaton, highlight how design is shifting towards environmental and community-centric solutions. These conversations also shed light on the emerging voices from the Global South, where innovative practices are addressing unique socio-political and environmental challenges. Architects from regions like Africa, Asia, and Latin America are offering fresh perspectives, pushing the boundaries of traditional architecture to reflect their diverse cultural narratives and local contexts.
The 29th United Nations Climate Change Conference (COP29) took place in Baku, Azerbaijan, from November 10 to November 24, 2024, amid a backdrop of escalating climate challenges. For cities, the epicenters of population growth, economic activity, and climate vulnerability, the outcomes of COP29 are particularly significant. As urban areas contribute over 70% of global carbon emissions and housing more than half of the world's population, their consideration is pivotal in shaping global responses to the current crisis. In fact, cities are on the frontlines of the crisis, facing record-breaking heatwaves, catastrophic floods, and increasing economic losses from extreme weather events. In 2024 alone, urban areas worldwide experienced devastating climate impacts: flooding displaced millions in Africa, droughts crippled urban economies in South America, and storms caused widespread destruction in North America and Europe. The outcomes of COP29 directly affect urban planning, architecture, and sustainability efforts. From commitments to climate finance and carbon markets to renewable energy and resilience-building, the summit's decisions provide a roadmap for transforming cities into hubs of climate innovation and adaptation. Below are the key takeaways from COP29 for the built environment and urban spaces.
The world has lost 60 percent of animal populations since 1970. This staggering decline reflects the growing pressures on ecosystems, from habitat destruction to climate change. And 1 million species now face threats of extinction. As these problems continue to escalate, the importance of preserving biodiversity and restoring ecosystems becomes clearer.
Buildings are deeply interconnected with their surroundings—the climate, culture, landscape, and the lives of their occupants. For Dorte Mandrup, a renowned Danish architect, context is more than a mere consideration; it is the driving force behind her designs. Her work demonstrates a profound curiosity about the people who will inhabit her buildings and the unique stories embedded within each site. Her buildings aren't just structures; they're thoughtful responses to their surroundings, without aiming to disappear within them.
Dorte Mandrup is featured, alongside Tosin Oshinowo, in the second installment of the documentary Women in Architecture, released November 12, 2024. Produced by Sky-Frame in collaboration with ArchDaily and directed by Boris Noir, the film builds upon the first episode, which highlighted Toshiko Mori, Gabriela Carrillo, and Johanna Meyer-Grohbrügge, offering a continued exploration of diverse perspectives within architecture.
Pavilions offer architects a unique opportunity to experiment, serving as compact spaces that push the boundaries of design and spatial concepts. Free from many conventional functional constraints, these structures allow for artistic expression and the testing of new technologies. Pavilions often act as living laboratories of architecture, positioned in public or cultural contexts. They transform their surroundings into interactive, memorable experiences, providing a stage for architects to showcase their most innovative ideas. In recent years, climate responsiveness has emerged as a crucial focus in pavilion design. By using temporary structures as a testing ground for more sustainable practices, architects can experiment with alternative materials and environmentally conscious approaches that address the climate crisis.
