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in particular increases the accessibility of information, the design and operation of schools remain, in a way, outdated.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.

In his Robie House, Frank Lloyd Wright created an ingenious arrangement of public and private spaces that slowly moving away from the street through a series of horizontal planes. Pronounced eaves made the interior space expand toward the outside. Considered the first phase of the American architect’s career, the so-called Prairie Houses had marked horizontality, mainly due to the enormous plans created by slightly inclined eaves. Eaves are ubiquitous in most traditional architecture, and in addition to their aesthetic role, they serve several important functions, the primary one being to keep rainwater away from the building’s walls and structure. But for some time now, we have seen plenty of projects with sloping roofs without eaves, forming pure and unornamented volumes. This brings us to the question: in these projects, how are practical issues such as draining rainwater?

Shortly before the First World War, Harry Brearley (1871-1948), who had been working as a metalworker since he was 12 years old, developed the first stainless steel. Seeking to solve the problem of wear on the inner walls of British army weapons, he ended up obtaining a corrosion resistant metal alloy, and added chrome to the cast iron. The invention found applications in almost all industrial sectors including for the production of cutlery, health equipment, kitchens, automotive parts, and more, replacing traditional materials such as carbon steel, copper, and even aluminum. In civil construction, this was no different, and stainless steel was soon incorporated into buildings.

In recent years, we have published many articles about wood. Addressing trends of use, possibilities for log wood, panels, curves, and finishes, innovations in tall building structures, and wood’s behavior towards fire, these articles have explicated a wide variety of the material’s applications and characteristics. A specific type of wood, Cross Laminated Timber (CLT), has emerged as highly structurally efficient with thermal, seismic, and even sensory benefits, described by specialists as the concrete of the future. But when we post these articles on social media, we frequently encounter comments from our readers concerned about the impact of deforestation. Although we may see wood as a great building material of the future, we must ask ourselves: is it possible to continue cutting down trees and using their wood while still calling it sustainable?

In the Genesis flood narrative, Noah built an ark after a call from God, who decided to flood and destroy all life on Earth due to the misbehavior of humanity. Only Noah’s family and a couple representatives of each species of animals could enter the huge vessel and save themselves. In the bible, the ark is described in the exact measurements of 300 cubits in length by 50 cubits in width by 30 cubits in height. This was a unit used at the time based on the length of the forearm, measured from the tip of the middle finger to the elbow. A Dutchman who has devoted himself to building a replica of Noah’s Ark, without success in finding a correspondingly accurate value in the metric system, used his own body measurements as a module. Modulation in architecture means adapting the project to a defined measurement based usually on a specific dimension or material. Whether it is a meter, a brick, a tile, or a container, it serves to guide the design process and make it more efficient and sustainable.

The Monadnock Building in Chicago began construction in 1891 and is still in use today. The building features a somber facade without ornamentation and a colossal height – at the time – of 16 floors. It is considered the first skyscraper built in structural masonry, with ceramic bricks and a granite base. To support the entire load of the building, the structural walls on the ground floor are 1.8 meters thick, and at the top, 46 centimeters. One hundred and thirty years later, this construction system remains common and allows for the erection of taller buildings with much thinner walls, accomplishing even new architectural works economically and rationally. But what is structural masonry about, and how can designers use it in architectural projects? And for what kinds of buildings is this system most suitable?

Every child has drawn a house. Perhaps a sunny day with some clouds, a leafy tree, a family with a dog, low wooden fences, or even a car. But in these drawings, they will almost certainly draw a simple rectangle with a gable or hip roof. This archetype of the house appears in virtually all cultures, and even today many architects use it for contemporary projects.

Cooking shows have never been more popular around the world than they are now. Whether from recipes, reality shows, or documentaries, writer Michael Pollan points out that it is not uncommon to spend more time watching than preparing our own food. This is a very curious phenomenon, as we can only imagine the tastes and smells on the other side of the screen, which the presenters often like to remind us. At the same time, when we watch something about the Middle Ages, polluted rivers, or nuclear disasters, we are relieved that there is no technology to transmit smells across the screen. In fact, when dealing with odors (more specifically the bad ones), we know how unpleasant it is to be in a space that doesn’t smell good. When dealing with buildings, what are the main sources of bad smells and how can this affect our health and well-being?

Ranging from yellow, to gray, to traditional red and orange, bricks are ubiquitous in many of our cities and widely used in construction. Briefly, the manufacturing process of traditional bricks involves molding clay and firing it in ovens, facilitating the creation of solid blocks, perforated blocks, cobogós, tiles, and other shapes. Ceramic bricks are inexpensive; easy to find; boast strong resistance, thermal inertia, and finish; and do not require such specialized labor for construction. But if the installation is done near sources of high heat, the common brick will end up cracking and breaking, making refractory bricks more suitable. But what does that mean?
