Polyvinyl chloride (PVC) plastic –commonly known as vinyl– is everywhere. In fact, chances are you are sitting close to (or on) something containing PVC in some way, shape or form. It’s used in packaging, automobile parts, children’s toys, clothing, accessories, wires, furniture, medical supplies and hundreds of other everyday items. This year alone, global production exceeded 51 million metric tons, solidifying its rank as the third-most produced plastic in the world. It is particularly in the architecture, engineering and construction industry that the material stands unchallenged, accounting for 60-70% of its total consumption. So much so that it has indisputably become the most used plastic for building materials worldwide, often found in pipes, fittings, flooring, roofing, window profiles and more. It’s not hard to understand why: PVC is durable, highly versatile, cost-effective and easy to maintain. But nothing comes without a cost, they say…
For decades, our society and the development of our built environment have been strongly associated with intensive extractive processes. While these methods were fundamental to the growth of urban areas, they also laid the groundwork for significant challenges that contemporary generations face today. Nowadays, construction debris accumulates on the peripheries of our cities, and plastic waste floats in the oceans.
In this context, and similarly to the idea expressed by Alvar Aalto, who stated that "modern architecture does not imply the use of new materials, but rather employing existing materials more humanely," it is crucial to reconsider how we manage our resources and waste. This shift in direction provides us with new opportunities to address the challenges that the ongoing climate crisis has brought. In response, various actions are now being taken, using materials such as food waste, recycled wood, and plastic debris, among others, exploring innovations in a context where raw materials are becoming increasingly scarce.

Mass timber is an innovative construction solution that is gaining prominence worldwide due to its sustainability and technological benefits. In 2020, the opening of the first Dengo concept store, located in São Paulo, marked the debut of the brand's first interactive factory and the pioneering use of CLT (Cross Laminated Timber) in a high-rise building in Brazil. Developed by architecture firm Matheus Farah and Manoel Maia, the project faced several challenges precisely because of its use of this new technology, which was just beginning to emerge in the construction sector.
The choice of CLT as the project's main building material reflects a commitment to sustainability and to reducing its environmental impact, as it helps mitigate carbon in the atmosphere. In addition, its use allows for cleaner, lighter, and faster construction compared to traditional building methods. However, it is important to keep in mind that mass timber construction requires special care in the handling, storage, and assembly of materials, in order to preserve their integrity and aesthetic details throughout the construction process. Using the right methods is therefore essential to guarantee a high-quality result, which include practices such as not leaving the wood exposed to weather or using wedges to prevent the wood from coming into contact with the ground.
Translucency, at its essence, is an optical property that enables the total or partial passage of light through materials, without providing a clear view of the objects behind them. Despite its apparent simplicity, this property has fascinating applications in the architectural field, generating attractive and powerful proposals that play with light without obstructing views.
Traditionally, glass sheets have been the symbolic material associated with transparency, commonly used in the fabrication of doors and windows. However, technological advances in production and the exploration of innovative materials have significantly expanded the opportunities to take advantage of this property in both interior and exterior applications. These advances challenge preconceived limitations and encourage creativity in the development of novel architectural proposals.

The use and demand for natural materials in architecture and interior design have facilitated the revival of updated traditional construction systems for the contemporary context. What was once considered rustic is now being explored in more modern settings; therefore, the application of the material is also subject to new forms of fixation, coloring, and orientation (horizontal or vertical). While wood is the dominant material in traditional systems and environmentally sustainable materials, another material that has been used for centuries, equally sustainable and biodegradable, and has received less attention is straw.
Double skin façades: Almost a self-explanatory name for façade systems consisting of two layers, usually glass, wherein air flows through the intermediate cavity. This space (which can vary from 20 cm to a few meters) acts as insulation against extreme temperatures, winds, and sound, improving the building's thermal efficiency for both high and low temperatures. Perhaps one of the most famous examples of double-skin facades is Foster+Partners' 30 St Mary Ax Building, "The Gherkin."
The airflow through the intermediate cavity can occur naturally or be mechanically driven, and the two glass layers may include sun protection devices.
As the architecture industry shifts its focus towards greater sustainability and energy efficiency, many modern projects in the world’s hottest (and getting hotter) environments are unearthing more traditional ways to control temperature, light, and ventilation by learning from the past to save us from the future.
Bricks are part of the collective imagination when thinking about construction. These are elementary, ubiquitous, modular, light, and reliable materials for erecting buildings. However, traditional ceramic block manufacturing relies on burning clay in kilns at high temperatures, often powered by non-renewable fossil fuels such as coal or natural gas. Furthermore, the transportation process significantly increases its environmental footprint, as the materials are heavy and bulky. In light of this, there is a growing interest in alternative construction materials that offer a lower environmental impact and greater sustainability. Soil cement bricks –or Compressed Stabilized Earth Blocks– are a good example of an existing alternative, as they have a smaller environmental footprint due to their use of local raw materials and the elimination of the burning process, while maintaining many of the intrinsic qualities of traditional bricks.
On the 3rd of February, this year's Lagos Biennial opened at the Tafawa Balewa Square, Lagos, an emblematic venue that was once the site of Nigerian independence celebrations in 1960. As the 4th edition of the art fair, it continues with its objective of using art to activate historic landmarks that have lost significance either through functional use or symbolic meaning to the residents of the former capital city.
The previous editions of the Biennial have explored various aspects of the city's architecture, its symbolic significance, political implications, sovereignty, ownership, notions of belonging, and its relationship with the public. This year, the theme of "Refuge" at the Tafawa Balewa Square takes this exploration even further. Curators Kathryn Weir and Folakunle Oshun highlight that this theme prompts the square to address the concept of a nation-state. It also brings together artists and architects from different disciplines to explore alternative approaches to constructing renewable communities and promoting climate justice.
Zaha Hadid Architects have released images of their design for the world’s first hydrogen refueling infrastructure for recreational boating. Continuing ZHA’s experience in maritime designs, the stations are to be installed in 25 Italian marinas and ports. Launched by NatPower H, the stations will begin to be implemented in the summer of 2024, with plans to expand to over 100 locations throughout the Mediterranean Sea in the next six years.
"If the cement industry were a country, it would be the third-largest emitter of carbon dioxide in the world, with about 2.8 billion tons, surpassed only by China and the United States." This statement in Lucy Rodgers' BBC report on the ecological footprint of concrete stands out as quite shocking. With more than 4 billion tonnes produced each year, cement accounts for around 8 percent of global CO2 emissions and is a key element in the production of concrete, the most manufactured product in the world. To give you an idea, about half a ton of concrete is produced per person in the world every year, enough to build 11,000 Empire State buildings. With these huge numbers, is there any way to reduce this impact?
The sun’s influence on human life encompasses multiple dimensions, from biological and developmental aspects to religious-mythological connotations in civilizations such as the Egyptians and Romans. Moreover, this influence extends to its use as a natural resource within the realm of science. In scientific pursuits, the continuous search to harness the sun as an energy source has been a constant throughout the years. Within this context, the discovery of the photovoltaic effect and its application have paved the way in the history of solar panels, starting from the first observations of Becquerel to the initial prototypes of Charles Fritts in the 19th century.
Nowadays, the energy obtained from the sun through devices such as solar panels has become one of the most widely used sources in regions like North America and Europe, contributing to the efforts for a complete transition to clean energy. The momentum in this transition has motivated the development of new technologies, such as SolarLab facade systems, that challenge the preconceived idea of what a solar panel looks like and where it can be installed. These systems converge with architecture to integrate them as aesthetic elements, serving as cladding for both retrofit projects and new buildings.

For a long time, sustainability in the architectural field was synonymous with technology. Efficiency was directly linked to innovative technological devices that adorned buildings with gadgets. Nowadays, however, sustainability increasingly encompasses different strategies that also involve acknowledging vernacular techniques and local materials as crucial for creating sustainable and carbon-neutral buildings.
Nevertheless, regardless of the technique or materials employed, the common denominator is the pursuit of reducing the carbon footprint of our architecture, which demands changes in how buildings are conceived, constructed, and operated. In other words, whether returning to vernacular methods or utilizing cutting-edge applications, these strategies aim to reach the same destination and, therefore, are equally valid despite being vastly different.
It's fascinating to observe the current state of wood in the world of architecture. The material, once seemingly forgotten by modernity, has resurged with full force, facing significant challenges but also revealing promising opportunities. The aesthetic and architectural appeal of engineered wood, coupled with its intrinsic association with sustainability, has been a catalyst for the increase in wood-centric projects around the world.
Due to technological advancements and research into the limits and possibilities of this material, there has been a significant leap in the development of wood in construction. Buildings around the world are being erected with wooden structures, driven by the increasing interest in sustainable solutions based on renewable resources, a demand from both the public and architects and their clients.
A few days before the end of November, Gramado, a city known as one of the most sought-after tourist destinations in southern Brazil, grabbed the attention of national and international media. Unfortunately, it wasn't due to its film festival or the traditional lavish Christmas festivities. The city, already suffering from weeks of persistent rain, witnessed the emergence of massive geological rifts tearing through its streets, creating a post-apocalyptic movie-like scenario.
The imminent danger of ground movement alerted the population and the authorities, who promptly evacuated the buildings on the hills of the condemned neighborhood. This course of action proved entirely effective and responsible, as one of the buildings within the designated area did indeed collapse three days after the evacuation. However, it is worth noting a detail: the affected neighborhood consisted of upscale residences and luxury hotels and inns, which raises a question: would the efforts have been the same if the situation occurred in lower-income peripheral neighborhoods?
The duality of sunlight in the field of architectural design presents fascinating contrasts, especially when addressing the question of how to interact with it through the built environment and the materials that define architecture. The sun's influence in this discipline has become an essential part of the cultural heritage of some countries, as evidenced by Spanish architecture, where the interaction with sunlight manifests through elements such as lattices. These lattices are recognizable on the facades of buildings from the Middle Ages, exemplified by structures like the Alhambra, to 20th-century constructions such as Casa Gomis, considered historical monuments.
The facade, being the skin of the building, is the architectural component that is usually directly exposed to sunlight. Based on this premise, we seek to establish a dialogue between openness to the environment and the need for protection, thus creating a synergy between functionality and aesthetics. In this context, sunscreen facades have been developed through various approaches, standing out for their ability to address this design condition. For this reason, we have selected solar control solutions from Spanish brands, distinguished by their technical characteristics and materiality through various approaches.

The global housing crisis generates a wide range of challenges, from those who are in situations of homelessness, to the realities of millions who face unaffordable housing conditions, overcrowding, and excessively high rents. Tackling this involves political will, the union of the state and private companies, and innovative solutions that prioritize accessibility, sustainability, and government mechanisms that enable a functioning system. Amongst all of these factors though, one thing is certain: we need to build massively in the future to improve the housing situation. The implementation of efficient construction methods, such as prefabrication and modular construction, can speed up the creation of affordable housing units, reducing construction costs and timeframes. Adopting green building practices, such as using recycled materials and designing energy-efficient structures, not only contributes to sustainability but minimizes long-term operating expenses for residents.
