The UIA World Congress of Architects 2023 is an invitation for architects from all around the world to meet in Copenhagen to explore and communicate how architecture influences all 17 UN Sustainable Development Goals (SDGs). The Science Track of the UIA World Congress has been tasked with the development of the agenda, Sustainable Futures – Leave No One Behind. For more than two years, its international Scientific Committee has been analyzing the various ways in which architecture responds to the SDGs. The work has resulted in the formulation of six themes: climate adaptation, rethinking resources, resilient communities, health, inclusivity, and partnerships for change. ArchDaily is collaborating with UIA to share articles pertaining to the six themes to prepare for the opening of the Congress on July 2, 2023.
As farmers water crops by moonlight, undocumented children head to school and villagers scan the sky for surveillance airplanes—these are glimpses of a complex culture that emerges in south Lebanon after dark. In collecting some of these nightly practices, Mohamad Nahleh—lecturer in architecture and urbanism at MIT—journeyed across the landscapes of Jabal ‘Amil hoping to build a new alliance between architecture and the night. His "Path of Nightrise" research has turned into a construction to revive a forgotten river path and was published by Places Journal. The interview with Nahleh argues for a new nocturnal imagination in design and reveals, not only how the night has changed in Lebanon over time, but also how he has changed alongside it.

A heavily cited fact within the architecture industry is that the built environment accounts for 40% of global carbon emissions. The concerning statistic puts immense responsibility on construction professionals. The idea of sustainability in architecture urgently emerged as a way of bandaging environmental damage. A wide range of sustainability practices aims no higher than making buildings “less bad”, serving as inadequate measures for current and future architecture. The problem with sustainable architecture is that it stops with ‘sustaining’.
In order to maintain the current state of the environment, the architecture community has been working towards greener means of production. Conventionally, a green building employs active or passive features as a tool for reduction and conservation. Most sustainable designs view buildings as a vessel of their own rather than integrated parts of their ecosystem. With the planet’s current needs, this approach is not enough. It is not enough to sustain the natural environment, but also restore its processes.
Country houses usually are found in remote areas, therefore, they often demand placement strategies that respect the context and dialogue with the landscape while bringing more thermal comfort and natural lighting. Most of the time, these solutions bring passive strategies that, along with the choice of materials and construction techniques, can provide an even more sustainable project. Get to know seven Brazilian residences that are examples of this theme.
In the contemporary context, as has been said a multitude of times, we seem to be living in what is classified as a digital age. A worldwide pandemic has enhanced the popularity of digital avenues to communicate — such as Microsoft Teams and Zoom, and the multiplatform messaging app WhatsApp is reported to have over 2 billion active users. From an environmental standpoint, we see the migration of businesses to the “cloud” heralded as a sustainability win. In simplified terms and to pick out a specific example, companies can refrain from storing data on external hard drives, opting instead to store their data on online file hosting services.
Form and function. Terms that accompany several definitions that belong to architecture, but more is needed to summarize the practice in 2023. Nowadays, building involves understanding the cycles of materials and how each action can be linked to the extraction of natural resources and their damage to the environment. We live in an urgent need to review the way we produce built space. In this search for models that move away from linear systems and provide a constant process of transformation and redistribution of matter, strategies arising from the circular economy emerge as a possible path. Its application in architectural heritage – for maintenance or restoration – can incentive the necessary changes toward a more sustainable society.

Every day, architects and designers tackle an ambitious task: crafting spaces that not only captivate the eye but that also nurture the health and well-being of those who inhabit them. A key part of this mission involves implementing design strategies that foster a pleasant indoor climate, as temperature, humidity and air quality all have a significant impact on users’ mood, productivity and overall health. Humans simply operate better if they are comfortable and content in their home or working environment. Although air-conditioning, ventilation and heating systems have conventionally served as popular solutions to regulate indoor climate, they often carry with them undesirable consequences –the presence of dust and bacteria, the need for regular maintenance and a cluttered, unappealing look. There is, however, an alternative solution.
“Our planet is choking in plastic,” states the United Nations. While the man-made material has many valuable uses, our addiction to single-use plastic products has led to severe economic, health and environmental issues. Roughly one million plastic bottles are purchased every minute, and five trillion plastic bags are used every year worldwide –used just once, then thrown away. Plastics and microplastics have found their way into every corner of our natural environment, from the peaks of the highest mountains to the depths of the deepest oceans. So much so, that they have become part of the Earth’s fossil record and created an entirely new marine microbial habitat known as the “plastisphere.”
World Wetlands Day is celebrated every February 2nd to raise awareness of wetlands. This day also marks the anniversary of the Wetlands Convention, adopted as an international treaty in 1971. Its enactment is because nearly 90% of the world's wetlands have been degraded since 1700, decimated three times faster than the forests. However, they are essential ecosystems that contribute to biodiversity, climate mitigation and adaptation, freshwater availability, world economies, and much more.
Perkins & Will has just begun construction on the Gateway Project for the University of British Columbia. The project will serve as the primary entrance point to the campus, as well as the new hub for the Nursing, Kinesiology, Language Science, and the university's health clinics. This project is inspired by the surrounding landscape and is informed by the Musqueam people, who have been occupying these territories for generations.
Students at the School of Engineering, RMIT University recently published a study experimenting with a new form of waste management and recycling. As they note in their research, cigarette butts are the most commonly discarded single waste item in the world, with an estimated 5.7 trillion having been consumed around the globe in 2016. However, the materials in cigarette butts—particularly their cellulose acetate filters—can be extremely harmful to the environment due to poor biodegradability. The RMIT study builds on a previous research study by Mohajerani et. al (2016) that experimented with adding discarded cigarette butts to clay bricks for architectural use. In their research, the RMIT students found that such a measure would reduce the energy consumption of the brick production process and lower the thermal conductivity of the bricks, but that other issues including bacterial contamination would have to be addressed prior to successful implementation. Below, we explore this research in more detail, investigating its relevance to the architecture industry and imagining possible futures of application.

Carbon footprint, circularity and environmental sustainability are terms that are increasingly present in many professional fields, but what do they mean? How do they relate to architecture and the built environment? We spoke with civil, environmental and sanitary engineer Lucas Rosse Caldas about these and other emerging architectural issues.
Lucas is a professor at the Graduate Program in Architecture at the Federal University of Rio de Janeiro and the Civil Engineering Program at the same institution. He participated in chapter 9 of the sixth report of the Intergovernmental Panel on Climate Change (IPCC) on buildings. He wrote several scientific and technical articles about architecture and sustainable construction.
Can you imagine being able to prototype a piece of furniture at the touch of a button and testing it in just a few hours? This might become a common practice sooner than we may think. Fueled by material innovation, automation and cutting-edge technology, a new era in home decor is emerging; one where 3D printing opens up a world of creative possibilities that transcend the bounds of traditional design. Yes, furniture is still mass-produced using conventional methods –molding, cutting, bending–, but 3D printing continues to disrupt the industry. As the revolutionary technology evolves and becomes more accessible, it has unleashed an unparalleled level of creative expression and efficiency. The concept is simple: a digital design is created using 3D modeling software and then printed, layer by layer, in the form of a physical object, bringing complex geometries to life. It’s a whole new kind of digital craftsmanship.
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.

The construction industry is one of the largest in the world, and cement and concrete are literally the building blocks of its success. Evolving from prehistoric caves to today’s towering skyscrapers, concrete structures have and will continue to be vital components of modern civilization, providing long-lasting, reliable support for buildings, roads, bridges, tunnels and dams. So much so that concrete is the most consumed material on Earth, second only to water, while the steel used to reinforce it is by far the most commonly used metal. But this doesn’t come without high environmental costs: concrete accounts for 8% of global CO2 emissions, much of which come from the extraction and transportation of aggregate materials such as sand, gravel and crushed stone.
The 2022 United Nations Conference of the Parties, more commonly referred to as COP27, was held between November 6 and November 18, 2022, in Sharm El Sheikh, Egypt. The conference included more than 90 heads of state and an estimated 35,000 representatives, or delegates, from 190 countries. Aimed at encouraging and guiding countries to take effective action against climate change, the next edition of these conferences, COP28, is already scheduled from 30 November to 12 December 2023, in the United Arab Emirates. The CEO of the Abu Dhabi National Oil Co, an oil company chief who also oversees renewable energy efforts in the Emirates, was appointed to preside over the negotiations and talks, which led to a wave of criticism from environmental activists.
Add cabbage leaves, orange peels, onions, bananas and a few slices of pumpkin to get... cement. That's right, researchers from the University of Tokyo in Japan have developed a technique through which it is possible to produce cement from food waste. Besides being used in construction, the innovative initiative is edible as well. You can make boiled cement into a delicious meal by adjusting flavors, adding seasonings, and breaking it into pieces.
