Chinese temples have stood for centuries, battered by wind and earthquakes, without a crack or timber out of place. They employ an ancient technique called “bracket set construction” that requires no nails or metal parts to connect wooden structural elements. Scandinavian stave churches are nearly as durable. Unsurprisingly, there are plenty of trees in Sweden and all over China.
So what is with the hype about innovation in “mass timber” construction over the past few years? As Boyce Thompson argues in his thoughtful new book, Innovations in Mass Timber: Sequestering Carbon with Style in Commercial Buildings (Schiffer Publishing), this will be the next big thing in “green” tech for architects feeling guilty about their costly titanium skins and outsized carbon footprints. The color photos show some impressive buildings in places where the wood industry has always been healthy, such as the Pacific Northwest and Scandinavia. The Japanese build log cabins with imported material that might as well be gold.
For decades, our society has predominantly embraced an extractivist approach when formulating models for material manufacturing across diverse industries. While we now know that this model is unsustainable, a major question remains: So, how do we do it? We may be a while away from offering a definitive answer to this challenge. Still, it is exciting to note that, in a context marked by a challenging global and ecological horizon, the architectural community maintains a positive approach by pushing for a re-evaluation of what we make and how we make it.
This momentum may be gaining relevance due to the emergence of new, more environmentally conscious generations, such as Gen Z and Alpha. What is certain is that we are witnessing the development of new production philosophies, such as plant-based materials, which adopt practices aimed at favoring the use of resources derived from plants, reducing dependence on extractive processes, and promoting conscious and sustainable alternatives in various aspects of the manufacture and production of materials in architecture.

“Landscape architects have started conversations about embodied carbon. There is a realization that we can no longer ignore the grey parts,” said Stephanie Carlisle, Senior Researcher, Carbon Leadership Forum and the University of Washington, during the first in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee.
The grey parts are concrete, steel, and other manufactured products in projects. And the conversations happening are laying the foundation for a shift away from using these materials. The landscape architect climate leaders driving these conversations are offering practical ways to decarbonize projects and specify low-carbon materials.
UNStudio, in collaboration with local partner HYP Architects, has won the competition for the design of the Kyklos building in Luxembourg. The project is part of Beval, a large-scale redevelopment initiative aiming to transform a former industrial site into an urban center complete with a university and technological center, in addition to residential, office, and retail spaces. When designing the Kyklos building, which will occupy a central position in the district's main square, the architects set out to find solutions to create the smallest carbon footprint for both operational and embedded metrics.
In an effort to find effective strategies to mitigate the adverse effects of climate change, the Biden-Harris administration has released a draft of a new legislative initiative that strives to impose a National Definition for Zero Emissions Buildings. Overseen by the U.S. Department of Energy (DOE), the draft proposes a standardized and verifiable base for defining the common minimum conditions for such buildings, as well as pathways for transparent verifications by public and private entities. DOE has now launched a ‘request for information' asking for feedback from industry, academia, research laboratories, and other stakeholders before finalizing the document.
Ghanaian-Scottish architect, academic, and curator Lesley Lokko has been announced as the recipient of the 2024 Royal Gold Medal by the Royal Institute of British Architects (RIBA), becoming the first African woman to receive the award. Lokko is not a practicing architect, but as a teacher, writer, and curator she has fought to widen access to the profession and to bring forward voices that have been disregarded for far too long. As the curator of the 2023 Venice Architecture Biennale, she has shifted the focus to Africa and its diaspora, exploring the complex themes of decolonization and decarbonization. For all her contributions to the profession, Lesley Lokko will be formally presented with the medal in May 2024 by Muyiwa Oki, RIBA’s first black president.
Innovative materials play a crucial role in shaping the future of architecture. They offer not only novel ways to craft buildings but also sustainable and efficient solutions to address pressing environmental challenges. Architects and designers are now more than ever exploring and integrating innovative materials into their projects. By harnessing the unique properties of these materials, they create structures with new visual languages while also being environmentally friendly.
As part of our year-in-review, we reflect on the innovative materials that were featured. These materials delved into the concepts of recycling agro-waste, adapting bio-based products, transforming local materials, and decarbonizing concrete. The objective was not only to offer alternatives to traditional construction practices but also to help reduce carbon emissions and promote a more sustainable built environment. In this dynamic field, these materials demonstrate the potential to revolutionize building design and construction in diverse contexts, paving the way for a more sustainable and resilient future.
COP28, or the 2023 United Nations Conference of the Parties, was held in Dubai between November 30 and December 13. The annual meeting gathers representatives from 198 countries, as well as industry leaders to discuss and establish strategies to limit the extent of climate change and its adverse effects. The ultimate goal of these meetings is to find ways to limit the global temperature rise below 1.5 degrees Celsius compared to pre-industrial times. At the moment, the global temperature rise is already at 1.2 degrees Celsius. As the construction industry at large accounts for 39% of global emissions, architects and planners have a shared interest in the results of thee international summit, Read on to discover some of the key takeaways of COP28.
If the past few years were a perfect occasion for reflecting and debating on well-being, digitalization, and democratization in architectural design, this 2023 has been a tremendous opportunity to delve deeper and comment on other urgent topics: The climate crisis and the natural environment have unquestionably entered the global agenda of architecture and construction, alongside circularity, energy efficiency, and decarbonization. It's time to engage in dialogue about these matters to conscientiously build for the future.
Reviewing the future of wood, water, and lighting, in each of the related topics that ArchDaily developed month by month, we posed an open question for you - our dear readers - to actively contribute with your experiences and knowledge. After reading and compiling an immense amount of received messages, from construction professionals to students and architecture enthusiasts, it's time to present you with a summary of the main perspectives. Many thanks for your opinions, and we look forward to your comments for 2024!
The 18th International Architecture Exhibition of La Biennale di Venezia closed on November 26th. A total of 285,000 people visited the exhibition, making it the second most highly attended Architecture Biennale in its history. Named "The Laboratory of the Future," this edition led by curator Lesley Lokko, has been the first to focus on Africa and its diaspora, exploring the “fluid and enmeshed culture of people of African descent that now straddles the globe,” in the words of the curator, with themes of decolonization and decarbonization.
This edition has attracted a wide array of visitors, 38% of whom are represented by students and young people. Visitors organized in groups represented 23% of the overall public, with a large majority of groups coming from schools and universities. The numbers denote an event centered on the transmission of knowledge and circulation of ideas.
On November 30, 2023, the UN COP28 climate summit begins in Dubai, the United Arab Emirates. The name stands for the Conference of the Parties under the UNFCCC, and symbolizes the annual meeting of world governments for the purpose of establishing strategies to limit the extent of climate change and its adverse effects. Last year’s summit concluded with several important measures, including the promise of a global fund aimed at providing financial aid to developing countries affected by climate disasters.
The main purpose of COP is to reinforce the commitments of the Paris Agreement, signed in 2015, which strives to keep the global temperature rise under 1.5C degrees. As the construction industry accounts for 39% of global emissions, architecture plays an important role in helping to lower our carbon footprint, making COP28 a crucial event for architects.
In light of the looming climate crisis and the pursuit of sustainability, the concepts of revival and reuse have emerged as crucial strategies in the quest for decarbonization in the architecture industry. These principles preach that creating new structures may be sustainable but encourage architects to minimize their ecological footprint by reactivating and recycling existing resources. This year specifically, innovative projects in line with these themes were displayed as part of the 18th International Architecture Exhibition – La Biennale di Venezia. This world-renowned event’s core purpose is to serve as a platform for architects, designers, and thinkers to collectively reimagine sustainability, decarbonization, resource conservation, and the industry's future.
The built environment is responsible for approximately 42% of annual global CO2 emissions. During a building's lifespan, half of these emissions come from its construction and demolition. To decarbonize architecture and control global emissions, it is important to rethink and reduce the upfront or embodied carbon impacts of demolitions, as well as implement sustainable construction strategies for buildings. Demolitions typically involve dismantling, razing, destroying, or wrecking buildings and structural parts, leading to unsustainable levels of carbon emissions, material depletion, waste, and pollution. These hasty methods of ending the life cycle of a building have negative impacts on the environment, material components, and recycling strategies. Therefore, there is a clear need to re-think the way in which we approach the end of a building or infrastructure project's life towards a more sustainable system of deconstruction.

Decarbonization of the building sector is no longer a choice but a necessity. As nations strive to curb their greenhouse gas emissions by 2050, it is increasingly clear that current building standards do not go far enough to drive tangible change. Achieving climate goals requires economies to advocate measures that drive carbon neutrality while managing associated costs effectively. How would net-zero performance strategies impact building costs?
Seratech's technology, developed by Sam Draper and Barney Shanks, eliminates the CO₂ footprint of concrete and reduces carbon emissions in construction. This innovative process uses silica, a waste product from flue gases, as a carbon-negative cement replacement in concrete. By incorporating silica, the required amount of Portland cement is reduced by 40%, resulting in the production of carbon-negative concrete. This groundbreaking technology won the 2022 Obel Award for its focus on embodied emissions.
The Obel Award is an international award that promotes architecture in the service of both people and the planet. Seratech was the fourth winner of this new international prize for architectural achievement, preceding this year's 'Living Breakwaters' by SCAPE Landscape Architecture. ArchDaily had the chance to interview Sam Draper, CEO of Seratech, about the company's role in building a sustainable construction industry and their plans for scaling their innovative process.
As we understand it today, the sustainable architecture movement began to take shape at the end of the 20th century. Essentially, it responds to growing concerns about environmental degradation, energy consumption, and resource scarcity. In this global discourse on sustainable architecture, wood has long been celebrated as a symbol of environmental consciousness and decarbonization. As one of the most widespread building materials, it has gained popularity with the rise of this movement. This is because trees absorb carbon dioxide during their growth, which stays in the wood during its construction use, keeping it out of the atmosphere.
For the opening of CAB 5, the 5th edition of the Chicago Architecture Biennial,Skidmore, Owings & Merrill (SOM) presented an eco-friendly alternative to traditional concrete. Named the “Bio-Block Spiral,” the installation is at The Mews in Fulton Market in Chicago. The creation was developed with Prometheus Material, a materials company that provides sustainable building materials for a carbon-negative future.
By the time I was 17 years old, I had moved 11 times. Because of my own experience relocating from one place to another, I’ve spent the better part of the last several decades focused on making sure that everyone has a place to call home, that everyone enjoys the human right to housing. But it was not until my time at Enterprise Community Partners, a nonprofit focused on community development and affordable housing, that I realized the methods and materials we employ to realize that human right matter.
