Fired clay has been used in construction for over 9,000 years, evolving from vernacular craft into one of the most widely applied materials in the built environment. Its durability, water resistance, thermal performance, and adaptability have made it a staple for facades, sanitaryware, flooring, architectural surfaces, and structural systems. Today, new manufacturing technologies are extending these possibilities as architects and manufacturers confront the environmental implications of material extraction and production.
What happens when you choose reuse over demolition? In Østbirk, Denmark, a 30-year-old timber warehouse has been transformed into a 14,000-square-meter world-class innovation hub for nearly 500 VELUX employees. This article explores how the LKR Innovation House project challenges conventional building practices, preserves material legacy, and offers practical lessons for architects working with existing structures. A new book documents the process through essays, interviews, and photographs.
In Six Memos for the Next Millennium, Italo Calvino explores lightness from a literary perspective and argues, "Opposed to lightness is weight. Removing weight produces lightness; it is a value, not a defect." Drawing on Greek mythology, he reflects on one of Perseus's feats after severing the head of the terrible Gorgon Medusa without being turned to stone. Assisted by the gods Hades, Hermes, and Athena, Perseus flies with his winged sandals and uses a bronze shield as a mirror to reflect her image. Relying, like many architects, on what is lightest—the wind and the clouds—he also fixes his gaze on what is revealed through indirect vision: an image reflected in a mirror.
Historically, transparency has been naturalized as an inherent condition of modern architecture. With the shift from the heavy load-bearing wall to the lightweight glass envelope, glass was introduced into the discipline, blurring the boundaries between interior and exterior spaces. In connection with inflatable architecture, transparency is linked to lightness and impermanence, leaving temporary traces on the landscapes it inhabits. By using textiles or plastics as main materials and air as a structural system, the search for lightness in the built environment now recognizes more than a single atmosphere of application.
Using massive s plates, often several centimeters thick and weighing tons, Richard Serra's sculptures convey an almost improbable sense of lightness. This effect does not result from a reduction of mass, but from how that mass is organized: large curved surfaces tilt, narrow passages compress the body, and seemingly unstable elements create a constant sense of imbalance. Serra transforms weight into a dynamic spatial experience.
In architecture, lightness has occupied a central role at least since the modern period. While earlier traditions, such as Greek and Roman architecture, were closely associated with stability, and large churches with monumentality, the twentieth century introduced a decisive shift in how matter is handled, particularly through the separation of structure and enclosure.

The ReGreeneration project, a Horizon Europe project led by Inetum and supported by C40 Cities, ARUP, Placemaking Europe, and several others, operates as an active collaboration with local governments, private companies, academia, and civil society organizations at the intersection of urban regeneration, green public spaces, and neighborhood-scale design. Its premise addresses how European cities are built and maintained and how they experience a changing climate, arguing that cities must fundamentally change to remain livable under accelerating climate pressures.
January 26 marks the International Day for Clean Energy, an initiative aimed at raising awareness and mobilizing action for an inclusive transition from fossil fuels, such as coal, oil, and natural gas, to power generation systems with lower greenhouse gas emissions and fewer pollutants. The term "clean" signals a fundamental shift away from extractive, finite, and exhaustible energy sources toward systems based on renewable resources or on capturing energy embedded in natural processes. In a world grappling with climate change, clean energy plays an important role in reducing emissions and expanding access to reliable power. However, being labeled "clean" does not exempt these systems from the impacts associated with their production, deployment, and commercialization. In this context, architectural knowledge related to space, materiality, and habitation becomes relevant for supporting a transition toward energy systems that are sustainable over time. As stated by the United Nations, the science is clear: to limit climate change, reliance on fossil fuels must end, and buildings must be heated, lit, and electrified through clean, accessible, affordable, sustainable, and reliable power sources.
The Commonwealth Association of Architects (CAA) is pleased to launch its 2026 Awards Programme, inviting architects from across the Commonwealth to submit work that demonstrates significant contributions to addressing contemporary global challenges including climate change, rapid urbanisation, biodiversity loss, and social inequality. Aligned with the CAA's charter objectives to maximise the contribution by architects to the well-being of society, the awards programme recognises projects and individuals whose work advances the United Nations Sustainable Development Goals (SDGs) while demonstrating exceptional design quality and measurable impact.

How does the construction sector shape the future of cities? What challenges does it face? At the crossroads of demographic, social, energy, and climate pressures, the construction sector is changing fast. Professionals, institutions, and citizens are working together to build environments that improve health and well-being, encourages durable and place-responsive solutions, cut carbon emissions, withstand climate risks, and provide affordable, high-quality housing.
Every act of building begins with the transformation of raw materials, energy, and land, and this inevitably entails environmental impact. This encompasses all the changes a process triggers in the natural world: from resource extraction to pollutant emissions, from energy consumption to biodiversity loss. Measuring this is complex, as it spans multiple dimensions. Carbon has emerged as the common metric, translating these effects into greenhouse gas emissions (CO₂ equivalent) directly linked to global warming. This standardization has made it omnipresent and comparable across materials, systems, and sectors. Reducing carbon emissions, therefore, means addressing the root of global warming, which is a particularly urgent task in the construction industry, responsible for about 39% of global emissions. In response to this challenge, MVRDV NEXT, the innovation and digital tools division of the Dutch architectural firm, launched CarbonSpace, a free, open platform that brings carbon accounting to the architect's desk, right at the napkin sketch stage.
The Deutsches Architekturmuseum (DAM) in Frankfurt has launched its new exhibitionArchitecture and Energy: Building in the Age of Climate Change on June 14, which will be open to visitors until October 5, 2025. Developed in collaboration with engineer and sustainability advocate Werner Sobek, the exhibition explores the intersections of architecture, energy, and climate, focusing on the environmental impact of the built environment and the role of architecture in mitigating climate change. By framing architecture as both a challenge and an opportunity in the context of the climate crisis, the exhibition seeks to contribute to a broader shift in thinking, one that positions design as a vital component of a sustainable future.
How do pavilions emerge in architecture? What role do they play in urban spaces? Beyond the multiple interpretations that exist around the world, the pavilion, as an architectural principle and typology, tends toward extroversion, often associated with a centrifugal nature and visual openness toward the horizon, which is linked to its origins as a tent offering shelter from the elements. Pavilions are usually identified as isolated and independent structures that can promote lateral openings in the urban space, panoramic or introspective views, technological reflections, and material experiments that are recognizable from the outside or once inside.
Material intelligence refers to how materials perform, adapt, and interact with ecological and cultural systems. It considers how stone, steel, or timber respond to intertangled forces, how those materials are sourced and assembled, and how they persist after demolition. Designers are centering material intelligence in constructing our cities in a generation of environmental uncertainty and strained supply chains.
