As awareness of water scarcity, water stress and environmental sustainability grows around the world, the concept of "water footprint" is becoming increasingly relevant. Unlike its more popular cousin, "carbon footprint", which focuses on greenhouse gas emissions, the water footprint (WF) provides a holistic view of water used throughout the life cycle of a product, process, or activity. It measures the amount of water consumed (directly and indirectly) and polluted –taking into account different types of water resources– and serves as a valuable tool for companies, policymakers, and individuals to understand and address their water-related impacts. There are even online calculators that measure our individual footprints through simple questions about our homes, appliances and even eating habits.
Composed of very fine mineral particles and formed through the weathering and erosion of rocks over long periods of time, clay has properties that make it useful for a wide range of applications. When wet, it becomes extremely malleable and plastic, and can be molded into different shapes. When dry, it is hard and rigid, and is widely used for construction and ceramics. Clay pavers are quite common for outdoor use due to their durability, resistance to weather and traffic, their natural hues and ease of installation.
In medieval cities, walls played a crucial function, acting both as a defense against external threats and as a symbol of power and control, while also regulating local trade. The access to the interior of these cities was strictly controlled by guarded gates, drawbridges, and portcullises, ensuring the free flow of local residents and simultaneously obstructing travelers and potential invaders. While fortified towers and armed guards are now primarily associated with prisons, creating access conditions that promote security, reliability, and practicality remains a challenge for architects and designers, especially in complex infrastructure projects such as airports, hospitals, and educational centers.
Ancient civilizations like the Egyptians, Greeks, and Romans understood long ago the importance of sanitation and wastewater management, building elaborate sewage systems by using underground drainage channels to carry wastewater away from their cities. These systems relied on gravity to transport wastewater to nearby bodies of water, since water cannot flow upward without being pumped. Today, many sewage systems continue using gravity in a similar way, with a suitable slope that facilitates the flow of wastewater downhill to treatment facilities or other infrastructure. This also occurs inside private lots, where a height difference is needed between the building's piping and the urban drainage or sewage system. But there are times when the available height difference is not sufficient, or when the system is lower than necessary, causing gravity to get in the way, and making the system impossible to function in turn.
When it comes to buildings, there are several factors that contribute to creating something truly luxurious: attention to detail, use of premium, high-quality materials, and unique designs. Lately, the environmental impact of building decisions has also entered heavily into this equation, and the development of a luxury project requires all steps and products to take sustainability into account. At One Za'abeel, the new addition to the Dubai skyline, the careful choice of all solutions, manufacturers and surfaces had a direct influence on the final look and atmosphere of the building, which aims to be an urban landmark and raise the standard of buildings in the UAE.
Finding effective and valuable solutions for agricultural waste management has been an inspiring challenge for researchers. By-products from monocultures, such as residues from soybean production, corn cobs, straw, sunflower seeds, and cellulose, are often destined for soil composting, used as animal feed, or even converted into energy in order to reduce waste and mitigate the environmental impacts associated with agricultural activities. Sugarcane production, for example, generates a significant amount of by-products, totaling about 600 million tons of bagasse fiber waste from an annual production of two billion tons of sugarcane. This by-product has a promising potential to replace energy-intensive building systems, such as concrete and brick, by providing building materials that combine sustainability and structural efficiency.
With this perspective in mind, the University of East London (UEL), in partnership with Grimshaw Architects and manufacturer Tate & Lyle Sugar, has developed an innovative building material called Sugarcrete™. The aim of the project is to explore sustainable building solutions by recycling biological by-products from sugarcane, which in turn reduces carbon emissions in the construction industry – all while prioritizing social and environmental sustainability during the production and implementation of these building materials.
Designing a good chair is a much more challenging task than we might think. To begin with, several factors must be addressed, such as ergonomics, aesthetics, materials, functionality and durability. In addition, it is essential to define the purpose for which it will be used: an office chair has different requirements than a reading armchair or a dining chair, for example. Only when all these elements are carefully balanced and thought-out can you achieve a truly excellent chair. And often, a good design can end up triggering many other variations throughout the years.
Some pieces of furniture are so versatile that they are equally at home in a home, in an office or in a cafeteria. The Liceo armchair by Piergiorgio Cazzaniga and the Triada table by Layer Design for Andreu World with height adjustement are perfect example of this. Image Cortesia de Andreu World
How can a space that is no longer essential become valued again? The traditional office as we know it is disappearing with the changes brought about by technological advances and globalization, all of which was accelerated by the impositions of the pandemic. As living and working become inseparable activities and hybrid, flexible work arrangements are now the norm in many fields, offices will need to become increasingly sustainable, healthier, and also more comfortable. But how can architects and designers design workspaces so that people will continue to want to inhabit them? What solutions and furnishings can meet the needs of occupants, with flexible solutions that can adapt to a variety of activities and purposes?
Seattle-based Olson Kundig is an example of how context and culture can influence a firm's design approach. Founded in 1966 by Jim Olson and now consisting of hundreds of employees and thirteen principals/owners, including Tom Kundig, the firm has an extensive and diverse portfolio that spans different scales and budgets. In lectures and interviews, Kundig in particular often talks about how having grown up in a region with a strong mining and lumbering tradition has influenced the industrial and rational aesthetic of his designs, the use of durable and low-maintenance materials, and a special attention to craftsmanship. In many of the firm's designs, however, the ingenuity and emphasis on moving parts –blurring the boundaries between inside and outside– is striking. This is usually achieved by incorporating hand-held devices that allow users to activate the building directly, connecting them both to the context but also to the building itself and the dynamic mechanisms therein.
By operating in closed cycles, circular design goes beyond the traditional linear concept of "extracting, producing, consuming and discarding", and seeks to create more sustainable and efficient systems throughout the life cycle of a product. Through the principles of reduction, reuse, recycling and regeneration, it can minimize the environmental impact of a product from the very first stages of its life: with the choice of more sustainable, durable materials; by minimizing waste during production; by promoting reuse and repair during its use; and at the disposal phase, with the efficient recycling of materials that can be reintroduced to the production chain. The adoption of circular design has gained strength in the industry, but despite the many advances and initiatives, it is still rare to see concrete examples of its implementation.
While most architectural critics and theorists agree that architecture can only really be learned on site –by experiencing its volumes, textures, sounds and smells– hardly anyone would have the time and resources to see all the projects they would like to in person. Ways of documenting a building or a city have aroused the curiosity of painters, photographers and artists throughout history. From the traditional classical portrait with perfectly adjusted proportions to disruptive forms such as Michael Wesely's long exposure images, Heinz Emigholz's experimental film set, or Tuca Vieira's Photographic Atlas of the city of São Paulo, there are myriad ways to portray the built environment. 360° cameras bring yet another set of possibilities to documenting architecture and urban scenes. We spoke to Romullo Fontenelle, architect and architectural photographer, who tested the new RICOH THETA X 360° camera and provided an account of how this technology can improve the efficiency and precision of his design processes.
Towers, walkways, decks, cabins and tree houses. Since 2010, the Hello Wood Festival has erected dozens of temporary constructions, with one common denominator: wood. The initiative aims to make knowledge about this material more accessible to everyone, as it has immense potential for the future. However, despite its potential, wood still faces various prejudices within the construction industry. Through the connection between designers and artists from different cultural, academic and professional backgrounds, the event uses construction as a platform for innovation, discussion and knowledge. It offers participants the unique opportunity to experiment with sustainable design and construction methods, encouraging learning through experience, held in a forested area near Budapest, Hungary.
Verticality in architecture conveys aesthetic, symbolic and cultural meanings, representing concepts such as elegance, sophistication, modernity, progress and technological advancement. In religious buildings, for example, it symbolizes greatness and a connection with the divine. These strategies are very common in Gothic architecture, as well as Art déco buildings or even the skyscrapers of Mies van der Rohe. But these elements need not be restricted to grandiose constructions. Even in single-family homes, working with elements that refer to verticality can be just as useful, playing with volumes and facades or working with openings, such as windows and doors.

Outdoor dining and activities have gained increasing appreciation in recent years. We value the sense of freedom and adventure, and the possibility of socialization that they provide, as well as the connection with nature. As a result, outdoor spaces are becoming more popular in residential and commercial designs, as new features made specifically for these types of spaces can enhance the comfort and well-being of occupants. This is because when dealing with nature there can be a variety of inconveniences related to weather, such as wind, rain, or cold temperatures. In order to properly enjoy these areas all year-round, solutions can usually include outdoor heating. However, typical heaters tend to have clumsy and old-fashioned designs, detracting from the careful design of the rest of the environment.
Acoustical comfort is a critical element of interior design that should never be neglected, especially in shared spaces such as restaurants, convention centers, museums, sports halls, and many others. Good acoustics can contribute to the occupants' well-being and productivity, while poor acoustics can lead to stress, fatigue, and even hearing damage. This can occur due to external noise, from various sound sources, or impacts (such as footsteps, jumping or moving furniture), but also due to the reflection of sound waves inside the environment, generating echoes and reverberations and reducing the intelligibility of speech in space.
Impressionist artists used the effect of "Optical Mixing" to create the illusion of color. By using short, separate brushstrokes of pure tones directly onto the canvas, the colors visually blended together as the observers moved away from the painting. For example, when painting a body of water, Claude Monet might have applied strokes of pure blue to represent the shadow areas and strokes of yellow to represent the light areas, which created the illusion of a green color, even though the painter had not actually added that particular hue to the canvas. In other words, each brushstroke has its own specific role in a painting, but also works for the whole image that is being created, through a careful choice of the elements present in the artist's palette.
Something similar happens with moodboards for spaces. Like a painter's palette, they are valuable tools for interior designers in the process of creating inspiring and functional spaces, allowing them to combine dissonant and unusual elements in favor of a harmonious whole. As a collage of visual elements, colors, typography, images, and words, carefully selected to represent the overall "mood" of the design, they assist in interior design decisions: materials and colors, coordination of design elements, exploration of concepts, and communication with the client, while also inspiring and directing the designer's creativity.
One of Paulo Mendes da Rocha's main design gestures in the Pinacoteca renovation project was to create a new longitudinal axis for circulation, moving its entrance to the south face of the building. Metallic walkways, which cross internal courtyards covered by skylights, enable new dynamics of circulation between the rooms, transforming a neoclassical building into a museum with a contemporary program.
The ability to completely renovate a space by demolishing parts, making additions, altering functionality, and improving ambience is one of the most admired functions of the architect. In housing, this significance is even more apparent, since adapting housing to contemporary demands, through a well-thought-out plan, can drastically improve the quality of life of the occupants.
Do you remember seeing images of designers leaning over large sheets of paper, usually in spaces that resemble warehouses, concentrating on their own technical drawings? While some may view these images with nostalgia for a simpler time as a sign of working passionately in the architecture, engineering and construction industry, many others might shudder at the thought of doing an entire project with an India ink pen, and especially without the convenience of the Undo tool (CTRL+ Z or command + Z). From the first CAD programs to the powerful modeling programs we have today, computing technology has radically transformed the landscape of AECO offices. In the past, integrating multiple designs required overlapping sheets of tracing paper; but today, we have a variety of software that produce files with numerous extensions, saved versions, sizes, and which often require powerful machines to run. With the growing adoption of remote and hybrid work in AEC organizations, implementing the right computer systems can be a major challenge.
