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.

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.

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.

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.

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.

Dozens of countries around the world have already banned the use of asbestos in the civil construction sector. Cheap to extract and abundant in nature, it is a natural fiber used to manufacture water tanks, insulation, partitions, tiles and decorative elements. Its properties include great flexibility and high chemical, thermal and electrical resistance, making it a seemingly ideal material. However, there is scientific evidence that links exposure to asbestos to several types of cancer, as well as to asbestosis – when the fibers of the mineral lodge in the pulmonary alveoli, compromising the respiratory capacity. The asbestos case shows how certain construction materials can –suddenly or not– become a distant memory because of their negative impacts. In addition to the effects on health, the use of materials with high energy consumption or made of rare raw materials is currently under pressure, as experts call to reduce their use or to make their manufacturing methods “greener”. The penalty? Disappearing in the near future, becoming yet another in the list of banned building materials. In this article, we delve into some of these materials and what their risks are.

Are you sitting comfortably right now? OK, I’ll wait a few seconds so that you can adjust your posture and we can continue the text. As much as we all know that our backs should be upright, shoulders back and glutes against the back of the chair, as soon as we stop paying attention, we tend to let our body slide down the chair until our spine takes the shape of a big question mark. This can lead to various posture and circulation problems, chronic pain, and increased fatigue after a long day, week, month, or years of work. But know that you’re not alone, and it’s not (necessarily) your fault. What elements make a chair comfortable? How can they help you maintain a proper posture for longer? Is it possible to have design and comfort in the same product? In this article we will try to answer these questions and show some examples from the Architonic catalog.

Roman aqueducts built more than 2,000 years ago are still in operation. The Pantheon in Rome remains the largest dome made of unreinforced concrete in the world, with a diameter of 43.3 meters. At the same time, it is not unusual to see structures less than a decade old collapsing. Understanding why Roman structures remain standing has been the subject of studies by many researchers around the world. Why, even in hostile environments such as coastlines or seismic zones, do these structures remain intact? Is there some miraculous material or method that has been lost in history? An international group of researchers led by the Massachusetts Institute of Technology (MIT) has shed light on these questions, discovering that these structures had a previously overlooked capacity for self-healing, and the potentially huge environmental impact it can have, to create more durable concrete structures in the future.

A metal façade introduces a visually appealing architectural element on top of a built insulation system, such as a vapor barrier, insulation board, and structural supports. Known for their versatility, durability and elegant, clean finishes, metal claddings can be used for both roofing and walls to deliver a long-lasting and eye-catching finished product made from natural materials such as aluminum, copper, zinc and steel. Regardless of which system is used to fix the panels (concealed clip system or exposed fastener system), a façade can be made from a variety of profiles and colors for unlimited design options. 

There are many challenges when working with renovations: adapting spaces that were not necessarily designed for a particular program, adding new uses for rooms and modernizing the building in order to make it compatible with contemporary demands. This was the case of Mobio Arquitetura’s project for the headquarters of a solar energy fintech company, which sought to value the memory of the historic building while adding a new layer of contemporary and technological infrastructure designed for the comfort, usability and productive coexistence of the new occupants. The office has been selected among the five winners of the 2022 Shaw Contract Design Awards “Best of Globe“.
