The 29th Conference of the Parties to the UN Framework Convention on Climate Change (COP29) takes place between the 11th and 22nd of November in Baku, Azerbaijan. The event proposes a global gathering of business leaders, governments, and civil society with the aim of taking effective measures to limit global warming to 1.5°C above pre-industrial levels. As the construction industry is responsible for approximately 37% of global emissions, the conference is of particular interest to architects, urban planners, and researchers in this field.
For decades, the construction industry followed a familiar rhythm: design came first, materials followed. The pressing need for sustainable buildings has shattered this routine. Material selection is no longer an afterthought, but a critical decision made at the outset, with the potential to dramatically reduce a project's environmental footprint. This shift is even more crucial given the construction industry's appetite for raw materials – a staggering 3 billion tons extracted annually. To navigate this new landscape, digital material libraries and data-driven evaluation are emerging as powerful tools, creating a culture where materiality takes center stage to shape a more sustainable built environment.
Evolving urban conditions call for an evolving builtscape, and retrofits have been a key mechanism to allow buildings to adapt and respond to new needs. Amidst global environmental concerns, climate retrofits have become a popular strategy to upgrade buildings based on improved operational efficiency. Global decarbonization plans have even called for city-wide retrofits, such as in the case of London, to meet civic goals. While such upgrades significantly reduce energy consumption, they often come with a hidden cost - embodied carbon in retrofit materials and the potential for future waste.
Located in the heart of Beijing’s Central Business District, the Z6 tower, designed by Foster + Partners, has become China's first high-rise office building to achieve “Net Zero Carbon Outstanding” certification. The project received this recognition by passing the “Net Zero Carbon Building Evaluation System,” which was developed by the British Research Establishment (BRE) and TÜV Rheinland Greater China, based on BREEAM standards.

Understanding a discipline from multiple perspectives and intersections is essential for acquiring a deep understanding of it. In architecture, the diversity of approaches to its study enriches our perception by allowing us to appreciate its complexity from different angles. For students and professionals alike, exploring aspects such as history, sources of materials and products, construction processes, implementation of new technologies, and contemporary social challenges is crucial. These aspects intertwine and expand the conventional notion of "architecture," transcending the mere creation of buildings or the definition of spaces.
Ronald Rael, an architect and the Eva Li Memorial Chair in Architecture at the University of California, Berkeley, exemplifies this vision through his practice, which spans from research to connecting indigenous and traditional material practices with contemporary technologies and issues. As an activist and designer, Rael's research interests explore additive fabrication, border-wall studies, and earth construction. Co-founder of Rael San Fratello, Emerging Objects, and Forust, his practice shows an approach to architecture that is highly relevant in contemporary times.

“The Mindfulness City will be a sustainable city. To be mindful is to be aware — to perform best,” said Giulia Frittoli, partner and head of landscape at BIG. The Kingdom of Bhutan is a landlocked Buddhist country in the eastern Himalayas, nestled between China and India. It covers 14,000 square miles and has a population of nearly 800,000.
The Royal Office of Bhutan asked BIG, Arup, and Cistri to develop a plan for a new Mindfulness City in Gelephu in southern Bhutan, near the border with India. The city will span 386 square miles and include a new international airport, railway connections, hydroelectric dam, university, spiritual center, and public spaces.
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.
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.
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.

Architecture encompasses multiple processes, starting with identifying needs and transforming them into habitable structures through thoughtful design. Historically, construction-related processes like resource extraction and end-of-life disposal were often overlooked. However, it is essential to recognize that buildings have a lifecycle with significant impacts on carbon emissions. Emphasizing sustainable practices is vital to minimize our ecological footprint and positively impact the planet.

CPC concrete slabs are based on the technology of "carbon pre-stressed concrete," which originated from a long-term research project conducted by the Zurich University of Applied Sciences Winterthur (ZHAW) and Silidur AG, Andelfingen. These panels are reinforced with thin, pre-stressed carbon strands, allowing them to be three to four times thinner and lighter while maintaining the same load-bearing capacity as traditional reinforced slabs.
CPC's innovative approach to concrete panel production reduces material usage by 75% and minimizes the carbon footprint of concrete production. ArchDaily interviewed Professor Josef Kurath from the Department of Architecture Design and Civil Engineering at the Zurich University of Applied Sciences (ZHAW), who collaborated with CPC Construction in developing these concrete panels. We discussed his perspectives on decarbonizing architecture, the inspiration behind the development of CPC panels, a comparison with traditional concrete, and the potential for scalability and accessibility in the future.

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?
Working within the restrictions of a limited carbon footprint can be one of the hardest – but also most rewarding – parts of a modern architect’s role. Whether to suit a large multinational corporation’s sustainability report, to achieve LEED status or similar for a commercial developer, or to build an eco-home for a climate-conscious private client – or even one who just wants to spend less on energy, it’s imperative to keep up-to-date with the latest carbon-neutral and low-carbon building practices and materials.
Whether looking at a project’s structural beginnings, its high-grade finishes, or thinking more holistically about its entire lifetime, there are huge gains to be made with sustainable substitutes and alternatives to traditional materials and techniques.
The window for solving climate change is narrowing; any solution must include embodied carbon. TheSixth Assessment Report published by the IPCC (Intergovernmental Panel on Climate Change) concludes that the world can emit just500 gigatonnes more of carbon dioxide, starting in January 2020, if we want a 50 percent chance of staying below 1.5 degrees. In 2021 alone, the world emitted about36.3 gigatonnes of carbon, the highest amount ever recorded. We’re on track to blow through our carbon budget in the next several years. To quote the IPCC directly: “The choices and actions implemented in this decade will have impacts now and for thousands of years (high confidence).”
Foster + Partners’ project for BENCH, one of the Philippines’ leading clothing and lifestyle brands, has started construction in Manila. The 24-storey headquarters building offers offices, design studios, event spaces, and the necessary amenities to create an enjoyable environment for the company’s employees. Located on the east-west axis in the Bonifacio Global City, the building opens up the ground floor to create a visual connection to the green space surrounding it.
Wood is the concrete of the future. As timber construction becomes increasingly popular, you have probably heard this phrase. However, we are not talking about traditional construction techniques using timber, but rather about this well-known material combined with cutting-edge technology.
As part of the Circlewood consortium, OMA’s David Gianotten and Michel den Otter have developed a modular system to build schools that can adapt and transform throughout their lifecycle. The system was selected by the City of Amsterdam to be employed to build multiple schools in the coming ten years, as part of the Innovation Partnership School Buildings program. The citywide initiative aims to build nine to thirty “high-quality, flexible, and sustainable” schools as a way to contribute to the city’s goal of becoming fully circular by 2050.
