It's very likely that you are reading this text in an interior space with the lights on. For most people, modern living entails spending most of the day in closed rooms, bathed in a sum of artificial and natural lights. Yet while artificial light has afforded mankind incalculable possibilities, it has also caused some confusion in our bodies, which have evolved for thousands of years to respond to the stimuli of sunlight in the day and darkness at night. This responsiveness to natural light is called the circadian rhythm or cycle, and describes the 24-hour biological cycle of almost all living beings. Circadian rhythms are primarily influenced by light reception, but temperature and other stimuli also play a role in the process.
Terrazzo is a mix of a concrete mixing base with natural stone fragments; it is characterized for being an extraordinarily resistant and versatile material. Since its frequent use some decades ago, this material has been rediscovered by architects and is used more and more often in works nowadays. Aside from the natural stones, this cement mixing base can include unused elements from construction – nails, bricks, and chunks of wood – resulting in very interesting final products.
The history of concrete dates back to ancient Rome, approximately 2,000 years ago. The so-called “Roman Concrete” is composed of limestone, volcanic ash, and seawater and it permitted the construction of aqueducts, highways, and temples; many of them still stand to this day. Some time ago, this original mix was discovered to form a mineral called aluminum tobermorite, which gets stronger as time goes by.
British company Kast has launched a new version of its traditional pigmented concrete sinks. Since concrete is an extremely versatile material, which combines the characteristics of natural stone with the ability to be molded in different forms, the products show carved surfaces with highly defined textures. The exploration of their linear patterns ranges from smooth horizontal ripples to diagonal folds or 'sharp' and vertical grooves. The organic variations in the colors and textures of the surfaces create a different aesthetic that comes directly from the character of the material.

The term "resilience" has been employed in a wide range of subjects. The scientific definition is the ability of a substance or object to recover its form after suffering some trauma. In other words, it is quite different from resistance, as it concerns the capability of adapting and recovering. In ecology, resilience is about the ability of an ecosystem to respond to a perturbation or disturbance, resisting damage and recovering quickly. In architecture, however, designing something while having resilience in mind can lead to a variety of approaches. Resilient designs are always site-specific. Predicting the potential scenarios for typical building use, and even any disasters that could challenge the integrity of the project and its occupants is an important starting point. Furthermore, it is possible to address adaptive structures and materials that can ''learn'' from their environment and continuously reinvent themselves. Since there are software and robots with algorithms that learn from their contexts, why can't we use the same approach in construction?
We have selected 10 adaptive materials and solutions that work under the concept of Resilience in Architecture and Construction. We are left wondering whether these solutions will someday become mainstream or merely occasional innovations.
Since the 1970s, humanity’s resource consumption began to exceed what the planet could renew in a year. That is, we are withdrawing and polluting nature more than it can naturally recover. According to the World Bank, if the world's population reaches even the projected number of 9.6 billion people by 2050, it will take almost three Earth planets to provide the natural resources needed to maintain humanity's current lifestyle.
Every day an enormous amount of carbon dioxide is released into the atmosphere through industry, transportation, burning fossil fuels and even respiration of plants and living things. As the consequences of climate change become clearer, both governments and private sector companies are setting targets for carbon emission reductions, since these are regarded as the main greenhouse gases, and their high concentration in the atmosphere lead to air pollution and acid rain, among other consequences.
Picture this. You're in a restaurant and you can hear the conversation of the person in the table next to you better than the person you're sitting with. Then, everyone begins to speak louder, making the environment chaotic. Absorption, reflection, reverberation, frequency, decibels, etc. Although acoustics is a complex science that can render buildings almost uninhabitable when not properly thought out, architects do not always possess the theoretical resources nor have the necessary concern to develop acoustically comfortable spaces.
European children spend approximately 200 days a year at primary school. Even though the academic year in most parts of the world is not as long as in Europe, the place where children and adolescents spend the most time, following their own homes, is usually in educational institutions. These can be places for learning, playing and socializing, and as sad as it may be, they can also be safer places for children living in environments of abandonment, hunger, and violence, providing them with opportunities and even meals. A United Kingdom-wide survey found that the differences in physical characteristics of classrooms accounted for 16% of the variations in learning progress over the course of a year. In other words, the better a classroom is designed, the better children perform academically. According to the study, the factors that most affect children are sunlight, indoor air quality, acoustic environment, temperature, the design of the classroom itself and the stimulation within it.
Ever since Manchester University first isolated Graphene in 2004, it has been widely referred to by its properties as a promising material through diverse research that focuses on reaching a range of uses in the most varied industries. Graphene is known to be one of the strongest materials known to science due to its composition of a single carbon atomic layer in a hexagonal mesh. It is also one of the finest materials known to mankind, 200 times stronger than steel yet 6 times lighter. Plus, it is an excellent heat and electricity conductor, aside from its interesting light absorption qualities. When combined with other elements, including gases and metals, it can produce different new materials with highly superior properties.
This is all quite recent: less than a year ago, a French family became the first in the world to live in a 3D printed house. Short of 20 years, this seemed like a distant dream, this new technology has developed quickly, and it arises as a possible contribution to the housing crisis around the world.
Thermal comfort becomes very evident when it is not attended to. When thermal conditions are adequate in one location, our body is in balance with the environment allowing us to perform activities normally. On the other hand, when a space is too hot or too cold, we soon see changes in our mood and body. Dissatisfaction with the thermal environment occurs when the heat balance is unstable, that is when there are differences between the heat produced by the body and the heat that the body loses to the environment.
During the modern period, the buildings that used the traditional sloping roofs with tiles, draining the waters as quickly as possible, have begun to give way to the well-known 'waterproof flat roofs.' In spite of delivering a clean aesthetic to the project, allowing the use of the last slab as a space for living and contemplation, this solution can become a headache for its occupants if its execution and design are not careful. It is no accident that there have been infiltrations in famous modern buildings, such as the Vile Savoye or the Farnsworth House, designed by great masters of architecture. Currently, the civil construction industry has developed more sophisticated products and techniques that drastically reduce the chances of subsequent infiltration. However, we could say that waterproof flat slabs continue to be fragile points in buildings. The architects from Brasil Arquitetura have improved an inventive and very simple solution to avoid infiltrations in flat slabs, much used in the 70's by architects like Paulo Mendes da Rocha and Ruy Ohtake, filling them with vegetation.
As ingenious solutions for environments that require additional space and ventilation, articulated or accordion doors and windows operate by folding their leafs one over the other and onto the sides of the opening. They moving via upper and lower rails which can be embedded into masonry and allow separation and integration rooms while adding aesthetic value to the project.
This system generates a similar effect to that of a sliding door or window, but it differs in that all its leafs remain in the same plane when they are closed, giving a clean appearance to the façade.
Glass is so present in our lives that it’s very difficult to think about the amount of work, experimentation and technologies behind each panel or glass object. It’s also impossible to separate innovations from modern architectural projects –from architects such as Mies Van der Rohe and Le Corbusier– from the advances of the glass industry.
We’re following the history of glass, from Mesopotamian artifacts to technological glasses, and we invite you to travel with us.
A technological innovation is revolutionizing one of the oldest professions in the world. Augmented reality has just broken onto the scene and has already been transforming civil construction. The changes are seen not only in designing and modeling, but also in building. Augmented reality benefits the entire construction team: engineers, designers, architects, project managers and service providers.
Unlike virtual reality, which creates a totally new and independent environment of the real world, augmented reality includes virtual elements that interact with what already exists. It is thus possible to combine virtual architectural designs with the reality of the construction site, increasing efficiency and accuracy, reducing the occurrence of errors and saving time, money and resources.
Let's suppose you need a bookcase. Years ago, you would probably search the furniture stores or antique shops in your town. Today you are more likely to open dozens of tabs on your web browser to compare prices and models. But there is another option that is becoming increasingly popular: open source furniture.
It's simple; you download the design of a piece of furniture and send it to a CNC machine (a mill that cuts wood from a digital file). It’s more or less like sending a PDF to print. With the pieces cut, you just assemble it. We used a bookcase for example, but it could be a chair, a table, a cupboard, a bench. Opendesk, one of the current open source furniture platforms, brings together about 30 pieces of furniture available for download. There the user can download a project and cut the furniture in a FabLab or personal workshop, or use the site to connect with a joiner who makes the cuts.
Studies show that public investment in integrated and safe cycling networks promotes urban transformation, providing more humanity, health and quality of life in urban spaces. While cities in the Netherlands and the Nordic countries have already incorporated bicycles into daily life, with a significant portion of the population using the means of transport for daily commutes, much of the world is still seeking a model to reduce congestion and increase its use. According to the Institute for Transportation and Development Policy (ITDP), investing in non-motorized transport allows congestion reduction, improves air quality, physical and mental health of residents, and local trade and brand visibility, once that cyclists tend to pay more attention to local commerce and take up less space than cars.
But along the cycle lanes and cycle paths it is essential to provide suitable places so that bicycles can be parked at the end of the trails. While bike stands are enclosed spaces, usually with some kind of surveillance and additional infrastructure, paracycles are the structures that allow to securely support and lock the bike. They can integrate in the urban furniture of a city, next to benches, plates, lamps and informative totems.
Cardboard tubes are so commonplace that we may no longer even notice them. Yet they are everywhere: in a roll of toilet paper, in the packaging of the college diploma, in fireworks, and in the tissue and paper industries. And now, more and more, they can be found in unusual places, such as on the walls of houses and buildings. The material is part of modern life and is being produced for a multitude of industrial applications and consumer products. The vast majority are used as structural cores in winding operations. Immediately after manufacturing, paper, film or textiles are rolled directly onto cardboard tubes resulting in a stable roll that is easily stored and transported.
