Materials: The Latest Architecture and News

The façade is one of the most important elements in an architectural project. In addition to being the building's first barrier against heat, rain, snow, or wind, it also largely determines the appearance of a building. It can make the project stand out, blend into urban context, or even manifest, at first glance, values of transparency, lightness, or simplicity that the architect seeks to convey. Accordingly, the façade also constitutes a significant portion of the total cost of the work and, therefore, must be specified very carefully, taking into account aesthetics, functionality, maintenance, and long-term behavior.

In dystopian films, it is a common trope to depict the sky as filled with a thick fog, blocking the sun's rays and bringing a dark atmosphere to the scenes. Whether in Blade Runner or in a Black Mirror episode, the lack of sun commonly represents a future we would rather not live in. The sun provides heat to planet Earth and is a great source of light energy, essential for the survival of many living creatures. We can generate electricity from the sun and still use only a fraction of the energy it provides. Sunlight also regulates our circadian cycle, which affects our mood. But recent forest fires and industrial pollution in some large cities have already made the dystopian blockage of sun a relatively common phenomenon, depriving hours of sunshine from many inhabitants. Concurrently, with the COVID-19 pandemic, we are living a plot that few science fiction writers could have predicted, and new technologies and solutions have emerged to try to contain the spread of this invisible enemy. Can the sun, or specifically ultraviolet radiation, kill viruses and bacteria? Could it kill the coronavirus?

Since immemorial time, humans have constructed their shelter and homes using wood. Gradually these structures grew more complex, but wood has continued to play a fundamental role in architecture and construction. Today, especially due to growing concerns about climate change and carbon emissions, wood has been regaining significance as an important building material for the future, if used consciously and sustainably. Wood’s structural performance capabilities make it appropriate for a broad range of applications—from the light-duty repetitive framing common in low and mid-rise structures to the larger and heavier, often hybrid systems, used to build arenas, offices, universities and other buildings where long spans and tall walls are required.

"And a window that looks out on Corcovado. Oh, how lovely." Tom Jobim's lyrics, immortalized by João Gilberto and Astrud Gilberto's voices and a soft guitar, was one of the early songs that introduced the world to the idea of a paradisaical Rio de Janeiro and a promising Brazil, with an increasingly urban population and a modern capital being built from nothing. Almost 60 years later, Paulo Mendes da Rocha casually quotes this song in an interview and points out that for him, in this scene, the most important element is the window, not Corcovado or Christ the Redeemer. That's because it frames the view and directs our eyes to what matters. It is a phrase that goes almost unnoticed, but that carries enormous poetic and artistic significance to the craft of architecture.

Polycarbonate has become an alluring alternative to glass in facades, as it has different levels of translucency and can provide optimal transmission and diffusion of light. Moreover, it is light, flexible, recyclable, durable, resistant to impact, and includes UV protection, in addition to resisting temperatures between -40°C and 115°C. But beyond its functional properties, this thermoplastic also provides wide-ranging aesthetic opportunities, allowing architects to create unusually dynamic and expressive facades.

In November of 2020, Foster + Partners announced a collaboration with the robotics design company Boston Dynamics. Together, the two have been testing Boston Dynamics’ robot dog, Spot, to help capture and monitor progress on construction sites. The robot boasts the dexterity to climb stairs, avoid obstacles, and traverse rough terrain, allowing it to monitor building sites and collect data quickly and easily. In this way, designers and contractors can remedy errors rapidly and at minimal cost, ensuring that projects progress according to their set timeframes and budgets. With manual data collection, errors might be noticed at a much slower rate and communication between contractors may suffer as well. Thus, Spot optimizes construction monitoring and on-site collaboration.

A single, continuous line unbroken by handle rotation: such was the simple, yet difficult-to-execute design concept motivating Zaha Hadid Design’s new innovative door handle. The result is a beautifully molded sculptural yet ergonomic design, playfully balancing form with function.

Little has been said about the contribution of scaffolding to the history of construction. These structures are generally treated as mere equipment and, as a result, their records are very scarce. Without scaffolding, however, it would be almost impossible to construct most of the buildings we know. Scaffolding allows workers to reach and move materials at difficult points in a construction, providing safety and comfort. But in addition to its role as a support structure for buildings, we have also seen that scaffolding can be used for mobile, temporary, and even permanent structures. Below, we explain its history and possibilities for use.

For companies or leasers that own large buildings, building maintenance can seem daunting, costly, or even superfluous, particularly when building functions appear to be running smoothly. But proper and consistent building maintenance is imperative for a number of reasons. Buildings inherently function less effectively over time due to natural causes such as climate, daily occupant use, mechanical obsolescence, and more. When left unresolved, these issues can devalue user experiences, create dangerous and unhealthy environments, and even incur costs higher and more sudden than consistent building maintenance costs.

Many of our childhood experiences take place in school. Whether these memories are good or bad, most children and teenagers spend a majority of their days in classrooms or other educational facilities. According to IQAir, “every year, children spend an average of 1,300 hours in school buildings.” But even as the world changes rapidly, and the internet in particular increases the accessibility of information, the design and operation of schools remain, in a way, outdated. As noted in a previous article, ideally the typology of educational spaces and the configuration of classrooms should suit more contemporary ways of teaching and learning, rather than the traditional organization of rows of desks facing a teacher at the head. But it is important that the analysis of educational facilities does not stop there. All surfaces and materials have a significant impact on both the well-being and learning of users.

Francis D. K. Ching [1] characterizes a chimney as an “incombustible vertical structure, which contains a duct through which smoke and gases from a fire or furnace are pushed outwards and through which an air current is created.” While its pipes can be hidden in walls or other structures, the chimney top usually remains prominent in order to transfer dangerous gases from the inside out without dirtying the interior or harming the health of the occupants. Being vertical elements, there are chimneys that become major landmarks in the urban landscape, especially in industrial projects. At the time of drawing, deciding on the “weight” that the chimney will have in a project is essential. At Casa Milá, for example, Gaudí crowns the building in sinuous and curvy sculptural chimneys. In other cases, the solemnity of the building aesthetic is mirrored in its chimney, whereas in others, the architects render the chimney as hidden as possible. Recently, too, many chimneys have been refurbished for new uses or to accommodate new cleaner technologies. Whether it takes a prominent role or is hidden from view, see below some chimney design tips and possibilities of use.

Floors, roofs, ceilings. Speaking in a very generic way, they are practically all the horizontal elements that we can find in the construction of a building. These three parts have a very similar way of modeling in Revit and this is the reason why when learning this software, they almost always appear one after the other. The order is usually a rather logical and therefore similar order: starting first with the floors, later the soffits and, finally, the ceilings. All this, clearly after having modeled the exterior and interior walls of our building.
