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.
In times of an ongoing global pandemic and constant video meetings, more and more people are leveraging their bookshelves at home to not only create appropriately stylish screen backdrops but also communicate credibility. There’s even a Twitter account on the subject. That being said, not everyone has a library-worthy collection to display or the space to store heavy art volumes. But whatever your personal shelf dream – even if it involves cats – here are five design elements that will help you make the most out of a tool you didn’t know you had, plus real examples of how they are being used to enhance bookshelves in projects around the globe. Head to the bookshelf section on Architonic for further inspiration and concrete product examples.
Overtaking the Tour First skyscraper, the 48-story, 220-meter HEKLA Tower will be the tallest building in Paris’s La Défense business district, as well as the second tallest building in all of France. Currently under construction and designed by Pritzker prize-winning Jean Nouvel, it is set to become a powerful architectural statement. Due to complete this 2022 in the midst of the sector’s redevelopment program, the futuristic skyscraper spreads over 76,000 sqm of floor area distributed in offices, services, lobbies, an amphitheater, projection rooms, performance halls, restaurants, bars, gyms and loggias. All of this with the aim of providing a unique user experience with vast, flexible workspaces that promote interaction and well-being.
A carbon neutral building is achieved when the amount of CO2 emissions is balanced by climate-positive initiatives so that the net carbon footprint over time is zero. Considering their unmatched ability to absorb CO2, planting trees is often viewed as the best carbon offsetting solution. But as cities become denser and the amount of available horizontal space for green areas drastically reduces, architects have been forced to explore other approaches. Therefore, to address these climatic challenges and connect people to nature, exterior green walls have become a rising trend in increasingly vertical cities. Even if there is research to claim that these can positively impact the environment, many question if they can actually contribute to a carbon neutral architecture. Although the answer may be quite complex, there seems to be a consensus: green walls can be effective, but only through good design.
Clay walls have a high thermal inertia. This means that they act as a climate buffer that creates a thermal delay in the flow of heat from the outside to the inside, absorbing it during the day and releasing it overnight. The material is especially suitable for hot and dry climates, such as that of Gando, where Francis Kéré built his first school. After years of studying abroad, Kéré returned to his home community with the intention of building this school with the same materials historically used by locals, which many originally viewed as strange, as he said in this lecture. Despite the initial prejudice, it was the combination of local materials and techniques with Kéré’s acquired knowledge that ultimately gave strength to the project.
SCI-Arc (Southern California Institute of Architecture) was created in 1972 and based on the concept of a "college without walls". Its original name was New School, which symbolized a paradigm shift in teaching architecture, focusing on a horizontal relationship between teachers and students and on experimentation, making it one of the few independent architecture schools in the world. In 2022, the institution turns 50 and has planned a calendar full of events and projects to take place throughout the year.
Among the many difficulties that the construction industry currently faces, confronting the climate emergency continues to be one of the main challenges. In fact, considering that the sector is responsible for around 40% of global greenhouse gas emissions, aiming towards net-zero, carbon-neutral architecture should and must be the top priority. Although there is a long way to go for most buildings to cancel out the amount of carbon dioxide they produce, the concept is quickly gaining traction and will certainly become the new norm as we look into the not-too-distant future. As a result, the following question arises: how can architects, designers and other actors involved in the industry contribute to sustainable design and net-zero architecture?
Advances in biotechnology and material science are opening new material opportunities, with the potential of fundamentally changing the connection between the built environment and the natural world. Building materials and construction account for 11% of greenhouse gas emissions. The AEC industry can contribute to curbing climate change in the following years, and the re-evaluation of commonplace building materials is one of the most critical steps. Bioengineered materials, which grow, produce energy, self-heal, are the next frontier in biology and material science and potentially a path towards a new kind of architecture. Although innovation in these fields is still far away from mainstream commercial use, it promises to dramatically change the image of the built environment.
Pipes, wiring and ducts of different materials in walls, ceilings and roofs make up all the spaces we walk through and inhabit. They represent the set of networks and equipment necessary for the development of life in our buildings, providing services such as water, electricity or gas, among many others. According to the regulations in each country and the use defined in each space, the installations can be left visible, giving a certain character and aesthetic to interior spaces.
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.
It is crucial to consider the future environmental impact of everything we create. Climate change remains high on the global agenda, and every industry must take part in the goal of reaching Net Zero. One of the more challenging industries concerns construction, which plays a vital role in the process of decarbonization and is constantly encountered with challenges to become greener. Therefore, it demands innovative techniques and development of data to find new and sustainable processes. One solution is to introduce and design both cleaner and more efficient materials. Bricks are a good example, as they can be used in building constructions to ensure a circular process and minimize carbon emissions, being an extremely durable material that can be produced with more sustainable techniques.
Exterior doors provide a sense of security and define first impressions, which is beautifully demonstrated in the pivot door presented above (designed and crafted in Europe by Air-Lux). On the other hand, inside of a house, interior doors are capable of generating privacy, buffering noise, separating rooms and enhancing a room’s architecture. Therefore, in order to fulfill these needs – and considering that they are used multiple times a day – interior doors must be durable and timeless without sacrificing beauty and style. Among all the options that meet these criteria, pivot doors stand out because of their elegant movement, aesthetics and versatility. With a sleek contemporary design that exceeds the regular function of a traditional door, these swinging doors rotate on a vertical axis with nearly invisible hardware, taking on any type of décor, use and measurement with endless creative possibilities.
In recent years, much attention has been given to timber constructions. Being a sustainable and renewable material, which captures a huge amount of carbon during its growth, the innovations related to this material have allowed for increasingly higher constructions. However, when we talk about wood we approach an immense variety of species, with different strengths, nuances, potentials, limitations and recommended uses. While there are extremely hard and heavy woods, with strengths comparable to concrete, there are other soft and soft woods that are suitable for other purposes.
By 2025, Dubai plans for a fourth of its buildings to be printed in 3D construction methods, demonstrating the potential of a fast-growing technology capable of redefining and pushing the limits of traditional architecture. As the technique emerges as a viable solution in the construction, engineering, and architecture areas, its popularity is quickly increasing. In fact, just between 2021 and 2028, the global 3D construction market is expected to grow by 91%, according to a July 2021 report by Grand View Research. Why this rapid growth? Besides being a faster alternative and having lower construction costs, it can also provide affordable housing solutions and allow countless design possibilities, among many other benefits. Thus, as architects must adapt to a new technological era, where speed and efficiency have become key factors in design and execution processes, the rise of 3D printing shows enormous promise. It could even help reshape construction as we know it.
The clothes used by nomadic peoples in the desert (Bedouins, Berbers, Tuareg, among others) are usually dark, long and made of heavy fabric. Contrary to common sense, which would recommend light, pale and short clothes for a hot climate; heavy and loose clothing favors air convection, creating a constant flow of air along the body, providing thermal comfort in arid climates. For buildings, the analogy works. When approaching energy efficiency and project performance, we will inevitably talk about its envelope, among other aspects of the project. A successful solution in one location, will not always be efficient in another.
A corridor that is too narrow, a poorly located switch or a simple unevenness can go completely unnoticed to many, but they can also be insurmountable barriers for someone with a disability. We all have a family member or acquaintance with mobility difficulties and, possibly, we might also experience them at some point in our lives. Architecture has the power to create truly inclusive spaces so that people with disabilities can have the autonomy to perform all necessary daily tasks, without needing the help of others. Integrated into architecture, technology can play an important role in this context, making the spaces in which we live even more accessible to everyone.
A recent study suggests that our home galaxy, the Milky Way, cannot be seen by one-third of humanity. Why? Millions of city lamps brighten our cities every night, but only part of their light is used to actually illuminate streets or sidewalks – the rest is lost and emitted above the horizon, brightening the night sky and contributing to what is known as light pollution. However, as the artificial glow from towns and cities increases every year, the consequences of this urban phenomenon go beyond just preventing us from seeing stars. Other harmful effects include: causing a hazardous glare that can reduce safety, excessive energy consumption, waste of money and resources, disruption of ecosystems’ natural day and night cycles, suppression of melatonin production and several negative repercussions on public health. In this sense, choosing the right lamps (with a well thought-out design) is crucial to reduce light pollution.
It is difficult to measure, observing a completed building, the amount of work, resources and knowledge that were deposited there. All decisions made influence in some way the performance of the building and its durability. As for the execution details, not all architects allow the dissemination of their constructive solutions. There are professionals, however, who go against the grain and focus on disseminating knowledge, identifying common design decisions that can lead to pathologies (such as leaks, rot, corrosion, mold and odors) and more economical ways to avoid them. This is the idea behind Building Science Fight Club, an Instagram profile whose purpose is to explain some issues and critically analyze certain constructive details and ways of installing materials. We spoke with Christine Williamson, creator of the platform, about her journey. See the full interview below:
