To explain the passage of time, the ancient Greeks relied on two gods: Chronos and Kairos. While the former is represented as ruthless, like a clock that never stops, Kairos evoked the opportune moment for action. In other words, while Chronos is quantitative, Kairos has a qualitative and permanent nature. Indeed, humanity's relationship with the passage of time is not always an easy one. 

Buildings are no different. In his seminal work The Seven Lamps of Architecture (1849), John Ruskin argued that only ruined buildings could preserve our past perceptions and, at the same time, allow us to confront our own mortality. In this sense, the marks of time and rubble were crucial witnesses to architectural aging, which, in his view, achieved an aesthetic somewhere between the sublime and the picturesque. Although this is a somewhat controversial perspective, the idea of considering how a building will endure over time has been gaining traction. It is well known that some materials age better than others: while a plastered white wall quickly shows cracks and stains, a stone wall seems to improve with age, blending into its surroundings, for example. Time brings new nuances, tells the story of what has passed, and lends authenticity to surfaces.

It could be argued that indoor air quality has never received its due attention throughout history. While atmospheric pollution has been considered a threat since the time of Hippocrates in 400 BC, becoming a tangible concern with industrialization during the Industrial Revolution, little is said about comfort conditions in indoor environments. This issue is increasingly critical given that humanity spends about 90% of its time indoors, and the quality of these spaces directly affects long-term well-being and health. In fact, Indoor Environmental Quality (IEQ) encompasses far more than just indoor pollution. It refers to a balance between air quality, acoustics, lighting, temperature, and other factors that contribute to a pleasant and, above all, healthy environment for occupants. Under the motto “every space can be a healthy space,” Armstrong has developed solutions to help improve the environments where we spend the most time, such as educational and healthcare facilities, offices, and homes.

When it comes to facades, there are numerous options to consider to define both the appearance and the message a building seeks to convey. While glazed surfaces bring sophistication and evoke corporate environments, exposed concrete offers sobriety, and wood lends warmth, few materials are as versatile for facades as HPL (high-pressure laminate). With a wide range of dimensions, colors, and textures, these panels easily adapt to different architectural styles, opening up endless creative possibilities. 

Humans have mastered ceramic manufacturing for about 15,000 years. Even today, it remains a widely used material in fields such as civil construction, crafts, and even high-tech industries. Because they are durable, cost-effective, and offer an immense variety of dimensions, patterns, and finishes, ceramic tiles are extremely popular finishes. Versatile, they can be used on horizontal or vertical surfaces, indoors or outdoors, in wet or dry areas. They are produced from a mixture of clay and inorganic raw materials; after being dried and fired at high temperatures (above 1,000 °C), the pieces acquire waterproof, easy-to-clean surfaces with a wide range of finishes and colors.

Designing for comfort—especially acoustic comfort—is a somewhat thankless task, as we typically only notice it when it fails to function properly. Common complaints abound: hearing a conversation from the next room more clearly than the one in your own space, having to shout to be understood by someone right next to you, or dealing with excessive echoes that make staying in a room exhausting. This last issue in particular is very common in spaces with exposed structures that lack finishing materials. Because materials like concrete, glass, or metal are typically not acoustically absorbent, spaces with industrial aesthetics often suffer from high reverberation times. This means that emitted sounds take longer to dissipate, continuing to bounce off surfaces and merge with other sounds, which creates disruptive noise and reduces speech intelligibility.

The New York firm Diller Scofidio + Renfro (DS+R) gained worldwide attention in 2002 with the Blur Building, designed for that year's Swiss Expo. The volume was formed by 35,000 high-pressure nozzles that sprayed water from the lake below, creating a massive artificial cloud. Its shape, boundaries, colors, and translucency shifted with the sun and wind, offering visitors an immersive experience as they entered a fully permeable volume. Ten years later, Carla Juaçaba and Bia Lessa designed Humanidade2012 for the Rio+20 United Nations Conference, where several programmatic volumes were arranged within a massive scaffolding structure. With more voids than solids, its edges dematerialized into the sky, and at night the volumes appeared to float. According to the architects, “the very movement of people through the building turned visitors into exhibits when seen from afar.” Despite differences in scale and context, both temporary projects succeed in working with notions of translucency, lightness, the dissolution of boundaries, and movement.

A faucet is a mechanical valve used to regulate (release or block) the flow of a fluid (usually water) from plumbing. While turning on a faucet seems almost mundane today, we rarely think about the vast knowledge and technology required to provide water at any given moment with a simple movement of the hand. Yet, between intake, treatment, and distribution to a kitchen or bathroom, water travels a complex path.

When entering a dark, unfamiliar room, our hands instinctively grope along the wall, searching for a keypad to turn on the lights—and, with luck, finding it. It is one of those many things we only truly notice when they are poorly designed. When designing a space, placing controllers in accessible and intuitive locations requires careful attention from designers. Keypads belong to that category of objects we want to be easily found when needed, yet prefer to remain hidden when not in use. This is because their design often draws more attention than it should, potentially clashing with the space's aesthetic. But this does not always have to be the case. There are options that seamlessly combine design and functionality, offering customization that allows controllers to fit into any type of project.

Steel frame is a system composed of galvanized steel profiles, with a thickness between 0.80 mm and 3 mm, cold bent, and assembled as structural frames, with vertical and horizontal studs. To wrap the structural profiles, OSB, cementitious or plasterboard sheets are used, which can be finished and painted internally and externally. Inside the walls, insulating materials can be included, such as mineral, glass wool, or others, to increase the thermal acoustic insulation. In the steel frame system, all the electrical and hydraulic parts are installed before closing the panels, making the process more efficient and without breakage and material waste. Cleanliness of the work, efficiency and speed are key points in this constructive system that is widely spread around the world.

Well-designed environments are essential to reduce the risk of accidents and response times in the event of a fall. For architects, designing safe cities and homes is crucial, especially in light of global demographic trends. Developing an architectural project through thoughtful design and correct product specification is, first and foremost, an act of care and concern for our older relatives and fellow citizens. It is essential to ask, "For whom?" and "What are their needs?" so that, from there, we can think about how to improve their quality of life.

This is a conscious invitation for architecture to play an active role in today's society—a positive shift that delivers both design and quality of life.

Transparent media allow light to pass through without dispersing it. Translucent materials, on the other hand, allow light to pass through in an irregular manner; because a portion of the light disperses, they prevent us from seeing through them with total clarity. Translucent surfaces act as veils, revealing without exposing, and literally blurring the boundary between interior and exterior. This effect is widely utilized in architectural design. From the signature facades of Steven Holl to the Moreira Salles Institute (IMS) in São Paulo, as well as many other examples in global architecture, this translucency can be achieved through specialty glass, acrylics, or other plastics. However, polycarbonate is a material that inherently delivers this effect, and it can be used in countless applications, from walls to skylights, and across highly diverse programs.

The escalating use of air conditioning is pushing urban temperatures to unprecedented heights. In highly populated nations like India, China, Indonesia, Brazil, and Mexico, major urban centers are becoming virtual ovens. At the same time, heat absorbed by buildings is re-released into the environment, driving local temperatures even higher. This outdoor heat, in turn, triggers demand for more air conditioning, creating a vicious cycle that increases both energy consumption and atmospheric carbon emissions.

In response to this feedback loop, UNStudio partnered with Swiss paint specialists Monopol Colours to develop “The Coolest White”—an ultra-durable coating that protects buildings and urban structures from excessive solar radiation, thereby mitigating the urban heat island effect. Darker materials used in urban construction are a primary driver of urban heat accumulation. These materials absorb up to 95% of solar radiation, re-releasing it directly into the atmosphere, whereas standard white surfaces reduce this absorption to 25%. Now, The Coolest White lowers this absorption and emission value to a groundbreaking 12%.

The concept of “resilience” is widely applied across many disciplines. In scientific terms, resilience is the capacity of a material or object to recover its shape after undergoing some form of trauma. In other words, it is quite different from resistance, as it fundamentally concerns the ability to adapt and recover. In ecology, resilience refers to an ecosystem's capacity to respond to disturbances, resist damage, and recover quickly. In architecture, however, integrating resilience into design can yield a wide range of solutions. Resilient design is inherently site-specific, making it essential to anticipate potential building use scenarios, and even disasters that could threaten the structure and its occupants. Beyond this, there is a growing focus on using adaptive structures and materials that can continuously learn from and modify themselves in response to the environment. If we already have software and algorithms that learn from their surroundings, why not apply the same approach to the building process?

We have selected 10 adaptive materials and design solutions developed under the concept of architectural and construction resilience—innovations that may one day become mainstream, or perhaps remain temporary experiments.

Today, October 18, the Casa da Arquitectura – Portuguese Center for Architecture opens the exhibition “Souto de Moura – Memory, Projects, Works,” which will remain on display until September 6, 2020. Curated by Francesco Dal Co and Nuno Graça Moura, the exhibition offers a unique monographic reading of the work of Eduardo Souto de Moura, 2011 Pritzker Prize laureate and one of the most prestigious Portuguese architects.

André Schmitt, one of the most respected architects in the state of Santa Catarina, passed away this Thursday (12). Schmitt served as Secretary of Tourism in the 1980s and was a frequent collaborator of the IPUF (Florianópolis Urban Planning Institute), actively participating in public discussions and contributing his knowledge to society. On Florianópolis' anniversary in 2018, he received the Virgílio Várzea Medal of Merit, an honor awarded by the Legislative Assembly of Santa Catarina.

The construction industry drives considerable economic activity worldwide, generating countless jobs and substantial revenue. At the same time, it also carries significant negative impacts, ranging from the depletion of natural resources to high levels of waste generation during both construction and demolition phases. To put this in perspective, in Brazil, Construction and Demolition Waste (CDW) is estimated to account for 61% of all waste generated, while household waste represents 28% [1].

Signs all over the city, on trains and subways. The words "Souto Moura" require no further explanation in a city with two world-renowned architects. It is the opening night of his exhibition "Souto de Moura: Memory, Projects, Works" at Casa da Arquitectura on October 18, 2019, and the two greatest leading figures of the so-called Porto School are there, side by side. Álvaro Siza, alongside other guests of honor, walks through all forty projects in the exhibition, listening to Eduardo Souto de Moura's concise, humble, and almost simple explanations of each one. They are Portugal's two Pritzker laureates, who also happen to live and work in the same buildings, in addition to having collaborated on several projects. Eduardo does not hide his pride in Siza's presence at his solo exhibition. Nor does he hesitate to acknowledge the master's influence on his career. Yet Souto de Moura's architecture is unique; it has a life of its own. And everyone there knows it.

From March 12 to 15, 2019, Expo Revestir brought together a vast array of national and international exhibitors along with over 60,000 visiting professionals. As Latin America's largest finishing solutions trade show and a well-established event in the construction and surface materials market, many companies take the opportunity to launch new products and showcase industry innovations.

Designing and mastering every part and stage of a project is inherent to the practice of architecture. Here at ArchDaily, we have previously featured architects who have developed designs for furniture and various other objects. Among this year's launches at Expo Revestir, several prominent architects have designed bathroom fixtures. This is the case for Angelo Bucci, Gui Mattos, and Tryptique, among others, in partnership with the manufacturer Docol.
