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.
There is growing awareness around sustainability—and the environmental cost of prematurely demolishing safe, structurally sound buildings only to replace them with new construction. In the broader race to reduce carbon emissions, corporations and institutions are placing greater emphasis on ESG performance (environmental impact, social responsibility, and governance). Many now require carbon accounting, set "carbon-neutral" targets, or purchase carbon credits to offset footprints.
This shift, together with a wave of exemplary adaptive-reuse projects worldwide—Herzog & de Meuron's Tai Kwun in Hong Kong, Powerhouse Arts in Brooklyn, David Chipperfield's The Ned Doha, and Xu Tiantian's transformations of factories, quarries, and rammed-earth fortresses in China—has accelerated serious reconsideration of reuse as a primary development strategy. Yet despite its many benefits, adaptive reuse is still not as prevalent as it could be. Why and what might be the main obstacles and tensions?
RSHP has announced the completion of the Barangaroo South Masterplan in Sydney, marking the realization of a 15-year redevelopment that has reconnected the city's north-western harbour edge to its urban core. Once a disused container port, the 22-hectare site has been transformed into a mixed-use, carbon-neutral precinct, integrating commercial, residential, and public spaces along the waterfront. Developed in collaboration with Lendlease following an internationaldesign competition, the masterplan is organized into three zones: Barangaroo South, a high-density extension of the Central Business District; Barangaroo Reserve, a reconstructed natural headland that reintroduces native landscapes to the harbour; and Barangaroo Central, a low-density residential area linking the northern and southern ends of the development.
Architecture firm Populous was chosen to design a new multi-use, climate-neutral event arena in Munich, Germany. The structure aims to create a "compact, efficient, and visually stunning" venue that will be instantly recognizable and reflective of the character and culture of the Bavarian metropolitan area, serving as a new landmark. The 20,000 capacity venue draws upon Bavarian heritage through a support structure that pays homage to the lozenge shape used in the Bavarian state flag. Populous developed the design with general planners HENN from Munich and landscape architects Latz+Partner from Freising.
The design incorporates a specific type of low-carbon concrete, which aims to emit 30% less CO₂ than standard concrete. The prototype will be featured in the Time Space Existence exhibition, organized by the European Cultural Centre.The goal of the project is to test the sustainability of a housing prototype in response to the ongoing climate and humanitarian crises.
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.
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.
While hybrid working and flexible hours represent the most obvious ways to improve work/life balance for many, because of the missed social interactions and the lack of space or functionality at unproductive home workspaces, the majority of 16-24-year-olds are the only age group who prefer to work from the office.

“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.
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.
BIG has just unveiled “Gelephu,” an envisioned master plan that draws from Bhutanese culture, Gross National Happiness principles, and spiritual heritage. During the 116th National Day of Bhutan, His Majesty King Jigme Khesar Namgyel Wangchuck introduced the plans for the prospective economic center in the country. Designed in collaboration with Arup and Cistri, the master plan is adhering to the sustainable standards of the world’s first official carbon-negative country, Bhutan.
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.

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?
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).”
BIG has partnered with experimental clothing brand Vollebak to create the vision for a self-sufficient off-grid island in Nova Scotia, Canada. The 11-acre Vollebak Island will receive several pavilions built of natural and innovative materials such as seaweed, hempcrete, and 3D-printed concrete, all powered by carbon-neutral energy. The island, located in Jeddore Harbor, one quarter off the Nova Scotia mainland, will be auctioned via Sotheby’s Concierge Auctions beginning June 8. Bidders will vie for the chance to own the island and to be granted exclusive rights to the design vision, including the planning permission for those designs.
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.
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.
