The use of pigmented concrete in Latin American architecture is growing - and influencing contemporary architectural expression. This can be seen in recent built works ranging from the INES Innovation Center designed by Pezo von Ellrichshausen in Chile to the Teotitlán del Valle Community Cultural Center by PRODUCTORA in Mexico.
As human beings we cannot live without stories, we need them to fill those gaps in our reality, to live in our imagination those thousands of lives that are different from ours and, in some cases, impossible.
Could we qualify as "good architecture" that which has a story, or several stories, to tell us? That which is a story in itself? Such a subjective question undoubtedly generates different answers, but one possible answer is "yes". And one example is the Brion Tomb project, one of Venetian architect Carlo Scarpa's major masterpieces.
The Benedictine monastery chapel of Santa María de las Condes, visible from different points in the eastern part of Santiago, Chile, is a white volume, located halfway up the slopes of Los Piques hill.
The expression "a perfect storm" refers to an event (typically an unfortunate one) which is exacerbated due to a confluence of negative or unpredictable factors. It is widely used when describing meteorological phenomena, but can also be applied to other contexts, such as the economy. The analogy can also be used to describe the relationship between the climate crisis and the world's dependence on concrete. As demonstrated in the Chatham House report, while cement (an essential element for concrete manufacturing) is extremely detrimental to the greenhouse effect and climate crisis –representing about 8% of global CO2 emissions–, its global production is nevertheless expected to increase over the next 30 years. It is said that this increase will stem from the demand for rapid urbanization in regions such as Southeast Asia and sub-Saharan Africa. At the same time, the last IPCC report warned that we only have 11 years to reduce emissions and prevent irreversible damage due to climate change. In other words, the cement industry is facing a significant expansion at a time when emissions need to fall rapidly – a perfect storm.
Canary Islands-born architect Fernando Menis has received the highest honor at the Faith & Form International Awards for Religious Art & Architecture in the United States, for his design of the Holy Redeemer Church of Las Chumberas in Tenerife. Co-sponsored by Faith & Form, Partners for Sacred Places, and Interfaith Design, the annual awards program has honored outstanding religious architecture since 1978.
When approaching the process of recycling building materials, there are a number of obstacles to achieving a comprehensive and effective result. First, careless demolition can make the process very complex, as products with different recycling products are often mixed. In addition, not all materials can be efficiently recycled or processed, as many still need expensive or overly complex processes. But the construction industry, being a huge contributor to waste production and greenhouse gas emissions, has also developed multiple new technologies to improve its practices. This is the case of the WOOL2LOOP project, which seeks to solve one of the biggest challenges in applying a circular approach to construction and demolition waste.
When browsing the 3D printing tag on ArchDaily, it is clear that this technology has developed at an incredibly fast pace. If in the early years we observed the concept as a distant possibility for the future or with small-scale examples, in recent years we have observed entire printed buildings and increasingly complex volumes being produced. Developed by reading a computer file, the fabrication is carried out through additive manufacturing with concrete - or other construction materials - and presents numerous difficulties in providing an efficient process that enables the constructive technique to become widespread. The pavilion printed by the Huizenprinters consortium, for example, illustrates this process well.
Seen as one of the great promises for the future of construction, carbon concrete mixes strength, lightness and flexibility. In addition, at a time marked by a serious environmental crisis that puts the construction methods of the industry in check, carbon concrete emerges as an alternative that approaches the guidelines of sustainability.
The oldest record of barrel vaults is estimated to date back to 4000 BC. These provided the spans in the Sumerian ziggurat at Nippur in Babylonia, built from fired bricks amalgamated with clay mortar. This type of vault was built as a continuous round arch and became a characteristic architectural element of Roman architecture, later used also in Renaissance architecture.
After water, concrete is the second most-consumed material on the planet and its production is substantially growing, expected to increase from 4.4 billion tons, reaching production up to 5.5 billion tons by 2050. Unfortunately, this comes at a huge environmental cost, accounting for almost eight percent of the global carbon emissions. With this estimated expected growth, stakeholders in the construction industry must work on integrating sustainable building materials and innovative processes.
Take a second to imagine a building or a room. Chances are you are envisioning flat rectangular surfaces and straight lines. Whether it be walls, beams or windows, most architectural elements come in standard and extremely practical orthogonal shapes. However, the pandemic has shed light on designs that are not only functional, but also that improve our mood and well-being. In that sense, the power of curved, free-flowing surfaces is unmatched, which explains why they have been making a comeback as a modern design trend. Adopting beautiful nature-inspired shapes, organic curls and bends energize rooms and make users feel good. In fact, neuroscientists have shown that this affection is hard-wired into the brain; in a 2013 study, they found that participants were most likely to consider a space beautiful if it was curvilinear instead of rectilinear. In short, humans love curves.
Dübendorf, Switzerland is something of hallowed ground for architectural technologists. There, on the shared academic campus of the Swiss Federal Laboratories for Materials Science and Technology and the Swiss Federal Institute of Aquatic Science and Technology, public university ETH Zurich has conducted nearly a decade of engineering and construction experimentation at the ever-evolving NEST research building. In August, ETH Zürich unveiled its latest extension of the building, HiLo (short for high performance-low emissions)—a two-story modular addition to the chameleon structure that harnesses medieval building principles and contemporary digital methods to raise the bar for more sustainable applications of concrete.
With the aim of generating a significant impact on the responsible and sustainable consumption of resources and energy in the construction industry, ETH Zürich in collaboration with FenX AG is using foam 3D printing (F3DP) to manufacture geometrically complex formwork for the construction of special elements in concrete.
The climate crisis has been one of the focal points of 2021, both within political discourse and the architectural field, accompanied by a newfound acknowledgement of the issue's severity. Over the past year, the IPCC report revealed the severe consequences of inaction, while COP26 and G7 summit resulted in an insufficient commitment to immediate and palpable measures. The AEC sector, responsible for a staggering 39% of global greenhouse gases, can bring a significant contribution to curbing climate change and the following looks at the decarbonization efforts of 2021 that target this industry.
As 2021 comes to an end, we look back at how this year introduced new normals and raised questions about what the future of the built environment could look like. In retrospect, not much has changed in regards to where people are spending most of their time. Following constant changes in commuting restrictions and the continuation of the pandemic, people acknowledged that most of their time will be spent indoors, so they adapted their living and working spaces accordingly.
These sudden lifestyle changes forced people to become well aware of the fact that the space they inhabit has great influence on their physical and mental wellbeing, so they began opting for features that promote sensitivity, calmness, optimism, and playfulness, emotions that counter the inconsistent and troublesome events taking place in the outside world and offer an implied sense of escapism.
Concrete and sustainability are two words that are often considered incompatible. Used as early as the Roman era, concrete has shaped much of our built environment, being the most widely used manufactured material in the planet thanks to its resistance, versatility, cost-effectiveness, and accessibility, among other inherent benefits. Its popular use in buildings and infrastructure forms the foundations of cities, connects communities, and will continue to play a vital role in providing solutions to the challenges of the future – especially as cities must respond to a growing global population. But with cement as its key ingredient, it also comes with several environmental costs, being responsible for at least 8% of the world’s carbon emissions in a climate-change context. However, it doesn’t necessarily have to be that way. With the rise of innovative technologies and products, there are many ways to make concrete greener.
A rock like marble is usually light in color when formed through a process involving the heat and pressure of limestone. Carrara marble, for example, became famous for having good workability for sculptures, but also for its extremely uniform appearance. Under skillful hands, rough stone could become works of art such as Michelangelo's Pietá or David, among many others. But if during the rock formation process there are impurities such as clay minerals and iron oxides, the resulting stone may acquire bluish, gray, pink and black hues. Something that would make its use in a sculpture unfeasible can be seen as the real beauty of the piece, and how the passage of time was printed on it. Likewise, it is very difficult to predict exactly how zinc or copper will oxidize over time, and its patina effect takes on beautiful greenish, reddish or grayish tones, depending on the conditions to which they were exposed.
Admiring the unpredictability of materials and observing the beauty of the unexpected can bring surprising results to architectural projects. Through constant research, Apavisa has been able to develop modular ceramic pieces that combine strength and versatility, reproducing in detail the materials that our environment gives us. The strength of stone and metal with their oxidative processes, the roughness and timelessness of cement or the beauty of marble with its different veins, shades and patterns.
Designed by architect Renée Gailhoustet in 1972, the Cité Spinoza residential complex is part of the master plan created for downtown Ivry-sur-Seine, France. The project is a rendition of the Unité d'Habitation de Marseille by Le Corbusier, a major architectural reference for architects at that time. Architectural photographer Anthony Saroufim took the streets of the Parisian Banlieue and captured the modernist architecture's distinct concrete geometry.
