At first glance, Dorte Mandrup's design for the Wadden Sea Center seems to mimic the landscape. Its low height, its horizontal lines and, above all, its materiality make it a modern building in perfect harmony with the local nature. But its connection also encompasses the built heritage of the region, more specifically because of its covering with straw, harvested and dried close to the land. This is an extremely traditional and historic building technique, but which is rarely attributed to contemporary buildings. In this article we will rescue some of the history of this natural material, its constructive characteristics and some examples of use.
UNStudio, in collaboration with local partner HYP Architects, has won the competition for the design of the Kyklos building in Luxembourg. The project is part of Beval, a large-scale redevelopment initiative aiming to transform a former industrial site into an urban center complete with a university and technological center, in addition to residential, office, and retail spaces. When designing the Kyklos building, which will occupy a central position in the district's main square, the architects set out to find solutions to create the smallest carbon footprint for both operational and embedded metrics.
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.
The use and demand for natural materials in architecture and interiors have enabled the revival of traditional construction systems updated for the contemporary context. What was once considered rustic is now being explored in more modern environments, therefore, the application of the material is also subject to new forms of fixing, coloring, and orientation (horizontal or vertical). Wood is the dominant material when it comes to traditional systems and environmentally sustainable materials. However, a 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.
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.
"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.
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 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.
The American Institute of Architects has announced David Lake and Ted Flato, the founders of Texas-based firm Lake|Flato Architects, as the winners of the 2024 AIA Gold Medal. The pair was selected by the jury for their ability to make "sustainability exciting in a way few other architects have accomplished." Founded in San Antonia in 1984, their office set out to make environmentally conscientious design both accessible and exciting, by finding ways to strengthen he bond between humans and nature.
Madagascar is an island nation off the southeast coast of Africa that, despite its lush vegetation and unique flora and fauna, grapples with formidable environmental challenges, from rising sea levels to the excessive exploitation of natural resources. Joan Razafimaharo is an architect deeply involved in sustainability, climate change, and adaptation efforts in Madagascar and the broader Indian Ocean region. Razafimaharo is also one of only about sixty architects in the country, serving a population of 28 million.
Recently I spoke to her about environmental activism in the face of climate change, curbing the exploitation of natural resources, the role of architects in resource-scarce societies, and empowering women in isolated areas. The interview, originally conducted in French, has been translated and edited for length and clarity.

The practice of upcycling –present in a variety of industries from fashion to construction– not only revitalizes discarded items, adding new values and functions, but also contributes to turning them into valuable resources. Adopting the spirit of the circular economy by harnessing agricultural waste such as corn cobs, rice straw, and sugar cane bagasse for building materials marks a fundamental shift towards sustainable practices, promoting a closed-loop system that minimizes waste and optimizes resource efficiency.
CornWall®, developed by StoneCycling, is a pioneering innovation in this regard. Inspired by the need to shift to a bio-based economy, it incorporates a transformative solution that addresses the pressing concerns of the construction industry's environmental impact. It is a wall-finishing material made from plant biomass, obtained mainly from the cores of regionally sourced corn cobs. This organic waste is widely available and is usually destined for fermentation, burning as biomass, or becoming simple organic waste. We spoke to Ward Massa from StoneCycling to better understand this material.
