Sustainability needs to go further beyond inspiring speeches and promises, with visible, concrete actions. In order to see this change, it is essential for individuals, companies and governments to take responsibility and act in a sustainable manner in their daily lives and practices. By taking into account the environmental and social impacts of their decisions and seeking more conscious and responsible alternatives, they can take steps to ensure a sustainable future for the next generations. In the construction industry this is even more urgent. Responsible for a large amount of solid waste and greenhouse gas emissions, it is essential for this industry to adopt sustainable practices, such as recycling, to minimize environmental impacts.

In the 1956 competition to design the city of Brasilia, Lucio Costa's proposal differed significantly from his competitors'. In contrast with the detailed plans and well-designed perspectives of the other competitors, the winning proposal presented the minimum required by the tender: a drawing of the pilot plan and a report. In the report, a few simple drawings supported the text, demonstrating the architect's ability to synthesize ideas in a few lines.

Starting from the first sketches of a project, it is essential that the project's design restrictions are well defined. This will guide the project, making it more suitable for its location, owners, and local conditions. Among common restrictions, keeping the project cost low is perhaps the most ubiquitous. We spoke with the VAGA team, an office based in São Paulo, about the challenges and possibilities that working with a tight budget imposes:

Every day, architects and designers tackle an ambitious task: crafting spaces that not only captivate the eye but that also nurture the health and well-being of those who inhabit them. A key part of this mission involves implementing design strategies that foster a pleasant indoor climate, as temperature, humidity and air quality all have a significant impact on users’ mood, productivity and overall health. Humans simply operate better if they are comfortable and content in their home or working environment. Although air-conditioning, ventilation and heating systems have conventionally served as popular solutions to regulate indoor climate, they often carry with them undesirable consequences –the presence of dust and bacteria, the need for regular maintenance and a cluttered, unappealing look. There is, however, an alternative solution.

To initiate change of any kind, one must first be aware of the problem at hand. In the construction industry –which is responsible for 39% of global greenhouse gas emissions and countless other environmental impacts– mastering and understanding the numbers related to its processes is extremely important. But assessing the impact of a product or a material is much more complex than one might think. It includes the exhaustive collection of data about its inputs (for example, the raw materials, energy, and water used) and outputs (such as emissions and waste) associated with each stage of the life cycle. This allows for the quantification of the embodied carbon and other environmental impacts, the identification of where performance can be improved, and provides real numbers for a comprehensive and unified comparison between materials and products.

The precast and prefabricated elements made of concrete (such as slabs, pillars, beams and walls) are part of the constructive process known as modular construction. A construction methodology carried out in stages, based on the standardization of the parts that make up the building, with its modules produced on an assembly line, transported and assembled to shape the architecture.

In recent decades, the industrial style has strongly attracted the attention of architects, designers and homeowners. However, few know its true origin. Following the rise of industrialization in the United States during the 1950s, many old industrial spaces, such as warehouses or factories, were abandoned in areas like New York's Soho. As a consequence, prices fell and became affordable housing alternatives for city dwellers. These new repurposed spaces were characterized by an aesthetic that mixed raw and exposed materials with modern elements and technologies, generating a strong aesthetic identity that was as rustic as it was sophisticated.

The United Nations estimates that the world population will reach 10.4 billion by 2100. Already by 2050, 2 out of 3 people will call cities home, coming in search of the opportunities, services and amenities on offer. That puts even more pressure on urban areas given all these people will need access to water, food, public space, good infrastructure and, above all, housing. In fact, estimates suggest more than two billion homes will need to be built by the end of the 21st century to accommodate this population explosion. As cities grow, so does urban sprawl, which brings its own set of environmental and social challenges. In the face of climate change, sustainable urban development must ensure that future housing solutions –new and renovated– are built to support healthy communities, prioritizing both human and environmental well-being. In turn, cities will need to be built denser and faster, but not without meeting a long list of stringent criteria. Only this way can we avoid the negative, often overlooked, effects of uncontrolled hyper densification that give urban development a bad name.

The Brick Award is an internationally established award that presents outstanding brick architecture from all around the world. Independent architecture critics, experts, architects and developers are invited to submit innovative and creative buildings and other construction works made of clay building materials. The spectrum of applications ranges from building solutions using classic clay blocks, facing bricks and roof tiles to the creative application of clay pavers and ceramic façade panels.

Ceilings were once a symbol of grandeur and opulence, adorning grand buildings, churches and palaces with their intricate and elaborate designs. We still find ourselves looking up in awe at these mesmerizing historical buildings, with our eyes drawn to their magnificent vaulted ceilings, remarkable truss structures or distinctive works of art depicting mythology, historical events and landscapes. Contemporary design, on the other hand, has shifted towards a sleek, minimalistic aesthetic; one where plain white ceilings have become the norm in most modern buildings. As Rasmus Wærn and Gert Wingårdh suggest in their book What is Architecture? And 100 Other Questions, “Ceilings have devolved from being the focal point of a room to being a zone for mechanical equipment.” And yet they have extraordinary creative potential.

Pretentious as it may sound, we can say with certainty that bamboo is one of the most promising materials for the future of the construction industry. Neil Thomas, principal engineer at atelier one, says that if we were to design an ideal building material, it would look a lot like bamboo. This is because it grows very fast, is present in many countries around the world, has a highly efficient cross-section, and has impressive load-bearing strength. But beyond its structural use in its raw form, bamboo is also a material that allows a high level of processing and can be laminated for flooring, fixtures and, as we will see in this article, for Structural Engineered Bamboo (SEB) structures, which are very similar to Engineered Wood. We spoke with Luke D. Schuette, founder and CEO of ReNüTeq Solutions, LLC, a company in St. Louis, Missouri, that has been working with this structural material technology.

Traditional building solutions tend to work well in their respective contexts, as they have withstood hundreds of years of testing and improvements, and use techniques and materials available locally. Although globalization and the democratization of access to technology have brought more comfort and new opportunities to humanity, it has also led to the homogenization of solutions in the construction sector and a dependence on global supply chains for construction materials and components. This has also caused a rupture in how knowledge is passed on to new generations and, eventually, the disappearance of traditions.

Students at the School of Engineering, RMIT University recently published a study experimenting with a new form of waste management and recycling. As they note in their research, cigarette butts are the most commonly discarded single waste item in the world, with an estimated 5.7 trillion having been consumed around the globe in 2016. However, the materials in cigarette butts—particularly their cellulose acetate filters—can be extremely harmful to the environment due to poor biodegradability. The RMIT study builds on a previous research study by Mohajerani et. al (2016) that experimented with adding discarded cigarette butts to clay bricks for architectural use. In their research, the RMIT students found that such a measure would reduce the energy consumption of the brick production process and lower the thermal conductivity of the bricks, but that other issues including bacterial contamination would have to be addressed prior to successful implementation. Below, we explore this research in more detail, investigating its relevance to the architecture industry and imagining possible futures of application.

Stabilized Aluminum Foam is a unique looking material that combines the aesthetics of aluminum (its texture, shades and brightness) with a spongy, porous appearance. It is produced by injecting air into a cast aluminum alloy with stabilizing agents, which after curing, creates a porous and lightweight, yet highly resistant and rigid cellular structure. Because of its mechanical and thermal properties, it is particularly useful in applications in various industries, such as automotive, aerospace and marine, especially for energy absorption, thermal insulation, and sound dampening.

"It's all about attitude and adjusting to the existing circumstances", explains Boonserm Premthada, when asked about his conceptual process. Founder of Bangkok Project Studio, and one of today's most influential Thai figures in architecture, Premthada has been the subject of Bêka & Lemoine's latest documentary, ‘Big Ears Listen With Feet’. The film highlights the personal story of the architect, unveiling all the events and happenings that shaped his unique identity and sensibility. "Deaf from birth", the short movie looks at how the architect's disability led him to listen in a different way, learning from elephants. who "despite their large ears [...] perceive sound mostly through their feet."

The world's oldest stained glass window (which is still standing) is conventionally believed to be in Augsburg Cathedral in the German state of Bavaria. Depicting the prophets David, Jonah, Daniel, Moses and Hosea, it is estimated to be nearly 1,000 years old, having undergone significant bombing during World War II. Long before that, however, mankind had been working with glass, and while today we have thin frames with crystalline sheets and a variety of properties, we had to come a long way to get here. In this article we will tell you a little about the evolution of glass windows and the technologies and possibilities that we have today.
