Carbon: The Latest Architecture and News

Bauhaus Earth is a Berlin-based non-profit organization working toward a systemic transformation of the built environment. Its mission includes transitioning to bio- and geo-based materials, reusing existing buildings, and restoring ecosystems. Together with the Bamboo Village Trust, a philanthropic financial vehicle, and Kota Kita, a participatory urban design organization, Bauhaus Earth has developed BaleBio, a bamboo pavilion designed by Cave Urban and rising above Mertasari Beach in Denpasar, Bali. The pavilion transforms a disused car park into an open community meeting space, offering a counterpoint to the city's tourism-driven coastal development. Designed as a regenerative building, BaleBio stores carbon instead of emitting it, challenging the extractive construction model that is replacing traditional wood and bamboo craftsmanship with concrete structures across the island.

Every act of building begins with the transformation of raw materials, energy, and land, and this inevitably entails environmental impact. This encompasses all the changes a process triggers in the natural world: from resource extraction to pollutant emissions, from energy consumption to biodiversity loss. Measuring this is complex, as it spans multiple dimensions. Carbon has emerged as the common metric, translating these effects into greenhouse gas emissions (CO₂ equivalent) directly linked to global warming. This standardization has made it omnipresent and comparable across materials, systems, and sectors. Reducing carbon emissions, therefore, means addressing the root of global warming, which is a particularly urgent task in the construction industry, responsible for about 39% of global emissions. In response to this challenge, MVRDV NEXT, the innovation and digital tools division of the Dutch architectural firm, launched CarbonSpace, a free, open platform that brings carbon accounting to the architect's desk, right at the napkin sketch stage.

The Deutsches Architekturmuseum (DAM) in Frankfurt has launched its new exhibition Architecture and Energy: Building in the Age of Climate Change on June 14, which will be open to visitors until October 5, 2025. Developed in collaboration with engineer and sustainability advocate Werner Sobek, the exhibition explores the intersections of architecture, energy, and climate, focusing on the environmental impact of the built environment and the role of architecture in mitigating climate change. By framing architecture as both a challenge and an opportunity in the context of the climate crisis, the exhibition seeks to contribute to a broader shift in thinking, one that positions design as a vital component of a sustainable future.

ACAN Sweden, in collaboration with Differ Agency, has launched "Embodied Carbon Declared," an online platform that actively reveals CO2 emissions data from new construction projects across Sweden. The platform categorizes and presents emissions data in four key areas: Projects, Municipalities, Developers, and Building Types. It provides detailed measurements both in total and per square meter, offering an advanced level of transparency in the construction industry.

“Embodied carbon accounts for 75 to 95 percent of the greenhouse gas emissions from landscape architecture projects,” said Chris Hardy, ASLA, PLA, senior associate at Sasaki, during the third in a series of webinars organized by the ASLA Biodiversity and Climate Action Committee. But by selecting locally made low-carbon materials, landscape architects can significantly reduce the climate impacts of their work.

Embodied carbon emissions are generated from the extraction, manufacturing, transportation, and construction of landscape materials. The other share of project emissions come from operating and maintaining a landscape.

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.

“Reinventing Cities,” C40’s renowned global design competition, has just announced its fourth edition. The competition’s main goal is to “transform underutilized sites or buildings into beacons of sustainability and resilience and act as a showcase for future zero-carbon urban developments.” This year, 15 cities have stepped up the challenge, inviting professionals from various disciplines to reimagine underutilized urban sites and design transformations prioritizing sustainability and inclusivity.

With a commitment to zero-carbon, urban resilient projects, Reinventing Cities has engaged over 3,500 businesses worldwide with 40 projects currently under development globally. This year’s competition is characterized by its ambitious environmental and social objectives; with participating cities spanning continents, including Almere, Bilbao, Bologna, Brussels, Glasgow, Milan, New York, Palermo, Renca, Rome, San Antonio, San Francisco, São Paulo, Seattle, and Venice.

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.

A simple walk in the park will relax even the most tightly wound individual. But what about the places where people spend far more of their time, such as schools, office buildings, and hospitals? What role can design play in incorporating nature into those environments? And at what additional cost? Bill Browning has published a book—The Economics of Biophilia: Why Designing With Nature in Mind Makes Financial Sense, 2nd Edition (written with Catie Ryan and Dakota Walker)—arguing that the cost of bringing nature into building projects isn't prohibitive but additive. An environmental strategist with a long history in green building, Browning is one of the founding partners (with architects Bob Fox and Rick Cook) of the sustainable design consultancy Terrapin Bright Green. Recently I talked with Browning about biophilic design—and, because he was a founding member of the U.S. Green Building Council's board of directors, about the strengths and shortcomings of the LEED rating system.

As we understand it today, the sustainable architecture movement began to take shape at the end of the 20^th 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.

The window for solving climate change is narrowing; any solution must include embodied carbon. The Sixth Assessment Report published by the IPCC (Intergovernmental Panel on Climate Change) concludes that the world can emit just 500 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 about 36.3 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).”

Refurbishment and adaptive reuse have been at the forefront of architectural discourse in recent years. This demonstrates that the profession is becoming increasingly aware of its impact on the environment and the opportunities presented by reusing what has already been built. Architecture 2030 has recently launched CARE, or Carbon Avoided Retrofit Estimator, a new digital tool that enables designers, owners, and communities to quantify the carbon benefits of adaptive reuse. By entering a streamlined set of project information, such as energy targets and potential building interventions, users can quickly estimate both operational carbon emissions generated by the use of the building and embodied carbon emissions, which are tied to the building materials employed.

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.
