OPEN Architecture’s Sun Tower, designed as a landmark for the Chinese coastal city of Yantai, topped out last month. On the summer solstice day, the 50-meter-tall structure reached its peak height. The landmark is expected to be open to the public in 2024. Acting as a cultural placeholder, the building reframes the typical understanding of "design with nature."

The buildings and construction sectors are key players in the fight against climate change –Combined, they are responsible for 30% of global final energy consumption and 27% of total energy sector CO2 emissions. Further, energy demand from buildings and construction continues to rise, driven by improved access to energy in developing countries, growing need for air conditioning, greater ownership and use of energy-consuming appliances, and a rapid growth in global floor area. Without targeted policy actions, the energy used in buildings could increase up to around 70% in 2050.
The climate crisis has made heatwaves more likely and more intense around the world. Record-breaking high temperatures are being reported across the world. According to international data, the first week of July 2023 was the hottest week on record, putting millions of people in danger. All throughout this summer, recurring heatwaves have been affecting large portions of Asia, Europe, and the United States, priming the land for fires in places like Greece, Spain, and Canada, triggering unhealthy air warnings, evacuations, and heat-related deaths. The increasingly threatening effects of the climate crisis are also felt in cities worldwide, as extreme heat proves to be a rapidly growing health risk to millions of urban dwellers.
Cities are on the front lines of this public health emergency. People living in urban areas are among the hardest hit when heatwaves happen, partly because of urban heat islands. This is a phenomenon that occurs when cities replace the natural land cover with dense concentrations of surfaces that absorb and retain heat, like pavements and buildings. Heat risk levels also vary by neighborhood, with less affluent and historically marginalized sectors being the most affected due to the density of the population, limited access to cooling systems, and the limited availability of green urban spaces.

Cities are defined as densely populated geographic areas characterized by urban development. They serve as economic, political, and cultural centers, offering various services, infrastructure, and opportunities. However, urban densification has been associated with negative aspects such as health issues, pollution, and social problems. Countries like India and China, with their massive populations exceeding billions, face a significant demand for services and housing.
Recent research, including studies by institutions like the Berkeley Cool Climate Network, has brought about a paradigm shift in our perception of urban densification. This shift aims to reduce cities' carbon footprint and support collaborative efforts to achieve Sustainable Development goals. Densification is proposed as a crucial strategy for promoting social prosperity, and well-being, and combating climate change. However, a relevant question arises: How can we effectively achieve densification while addressing global warming? Companies like Holcim have responded to this challenge by developing sustainable building solutions and engaging in meaningful discussions with architects, such as Shajay Bhooshan, Associate Director at Zaha Hadid Architects. These collaborations provide valuable insights into the concept of urban densification as a catalyst for climate action.

As the challenges posed by climate change increase in number and intensity, it also heightens the need to find sustainable building practices that connect to ecosystems and livelihoods rather than harm them. While often overlooked in the search for innovation, vernacular architecture can offer answers to contemporary issues. This type of architecture not only relies on readily available locally sourced materials but also on indigenous knowledge of local conditions like sun orientation, wind patterns, ventilation needs, and the behavior of materials in time. Dr. Sandra Piesik, director and architect of 3 ideas, and founder of HABITAT Coalition, explores this potential in her newest book, 'Habitat: Vernacular Architecture for a Changing Climate.'

This Earth Day, U.S. Vice President Kamala Harris highlighted the many benefits of nature-based solutions and recognized the important role of landscape architects in this work. At the University of Miami, she also announced $562 million in funding for coastal resilience projects, supporting 149 projects in 30 states, through the Climate-Ready Coasts Initiative of the National Oceanic and Atmospheric Administration (NOAA). Vice President Harris’ remarks build on the Biden-Harris administration’s support for planning and designing with ecological systems in an equitable way.
For the 18th International Architecture Exhibition – La Biennale di Venezia, The Albanian Pavilion set out to respond to the theme “The Laboratory of the Future” with the exhibition “Untimely Meditations or: How We Learn to Live in Synthesized Realities.” The project seeks to introduce and understand new typologies of civic spaces by repurposing the rendering engine as a mechanism for exploration. The curatorial team is composed of architects Martin Gjoleka, and Era Merkuri, exhibiting together with architect Ani Marku and 3D digital artist Geraldo Prendushi.
Skidmore, Owings & Merrill have been selected to design the New YorkClimate Exchange in partnership with Stony Brook University, a public research institute in New York. The new net-zero campus, located on Governors Island, New York, is planned to serve as an anchor institution for the development of new climate solutions. As a first-of-its-kind international center, “The Exchange” will also act as a regional hub for the green economy.
Rising over global cities, the modern skyscraper has long been a symbol of economic growth and environmental decline. For years, they have been reviled by environmentalists for being uncontrolled energy consumers. Malaysian architect Kenneth Yeang acknowledged the skyscraper as a necessityin modern cities and adopted a pragmatic approach to greening the otherwise unsustainable building typology. Yeang’s bioclimatic skyscrapers blend the economics of space with sustainability and improved living standards.
Every year since its establishment in 1970, Earth Day aims to bring into focus not only the increasingly threatening effects of climate change but also highlight the effective measures and adaptation efforts that can improve the quality of our environment. This year’s event comes after a report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC) in March, which presented another warning on the magnitude of changes produced by human-induced global warming and its impact on people and ecosystems. The same report does offer some hopeful prospects as well, showing that adaptation measures can build resilience, but those urgent systemwide transformations are needed to secure a net-zero future. In response to these findings, the 2023 Earth Day is focused on the theme of “Investing in Our Planet,” as an encouragement for governments, institutions, businesses, and civil society to accelerate the change. Read on to discover several citywide initiatives aligned with these objectives of building resilience and a more sustainable future through legislation, civic involvement, and innovative systems.
MVRDV has joined the Van Gogh Homeland Foundation to develop the first Van Gogh Homeland Biennale to bring awareness to the challenges faced by the Brabant region. At the initiative of Midpoint Brabant, the experience strives to combine knowledge of architecture, landscape design, and sustainability to reignite enthusiasm for the Brabant landscape, Vincent van Gogh;s native Dutch province. According to the organisers, the region is facing a number of threats, including the increasing number of floods and the limited availability of space, but, through an orchestrated effort, the landscape that inspired van Gogh 150 years ago can become more sustainable and greener in the future.

During the 19th century, efforts to improve the quality of urban life focused on creating gardens and parks, marking the beginning of the evolution of landscaping as a modern discipline. However, despite remarkable examples worldwide, excessive structure and artificiality in urban parks have gone against the motivations that gave rise to them. In many cases, their design has resulted in decontextualized and inefficient public spaces that are highly demanding on resources and far from being truly sustainable.
The strict use of geometry and the imposition of species that are difficult to adapt and care for are gradually giving way to a more organic approach to landscaping, tailored to local ecosystems and more efficient in its development and conservation. Native forests embody all these positive aspects. They not only ecologically restore degraded areas but also improve air quality and retain rainwater, creating biodiverse green spaces that deeply connect people with nature. We spoke with Magdalena Valdés, founder and director of Bosko, who explains why native forests are the right path towards conscious and truly ecological landscaping.
In each region of the globe, vernacular constructions of the most varied kind emerged, whether buried underground, inside caves or even built with stones, wood and fabrics. Shelter solutions were based on available materials and weather conditions. The architecture arises from the development of these shelters, built to protect people from predators and the weather.
The construction solutions employed thousands of years ago have evolved and become increasingly complex but kept a common goal: dealing with the weather.
At the 2023 Biennale Architettura, Finland's Pavilion will present its exhibition Huussi, Imagining the Future History of Sanitation, which deals with the architecture of water and nutrient circulation, questioning the water toilet and Its implications for the future. "Huussi" is the Finnish word for an outhouse, a small compost toilet commonly used by Finns in rural settings and holiday homes. The exhibition, curated by Arja Renell and The Dry Collective, a group of Finnish architects, presents this typology as a starting point to finding alternative solutions to managing wastewater, inspiring professionals to start envisioning new sanitation solutions. At the core of the presentation, the exhibition questions the consequences of waste in the context of the current climate crisis the world is going through.
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.
