Researchers point out that "proto-greenhouses" arose to fulfill the desire of the Roman Emperor Tiberius (42 BC to 37 AD) to eat cucumbers every day of the year. Since it was impossible to grow the vegetable on the island of Capri in winter, his gardeners developed beds mounted on wheels that they would move into the sun when possible, while on winter days they would place them under translucent covers made of Selenite (a type of gypsum with a glassy appearance). But the production of large-scale greenhouses only became possible after the Industrial Revolution with the availability of mass-produced glass sheets. Since then, they have been used to grow food and flowers, forming a microclimate suitable for plant species even in places with severe climates. But in some cases, these artificial growing conditions can also form interesting living spaces. The recent Lacaton & Vassal awards rekindled this interest. How is it possible to create greenhouses that can be good for both humans and plants?
June 8th was World Oceans Day 2023, which brought the theme 'Ocean Planet: Tides are Changing'. The purpose of the United Nations was to generate a "new wave of enthusiasm for caring and protecting the ocean and the entirety of our blue planet."
A new opportunity to reflect on the importance of preserving these vast aquatic ecosystems that cover more than 70% of the Earth's surface - and an opportunity to reflect on how architecture can contribute to their protection and conservation through the design of resilient coastal infrastructure, the development of marine energy technologies, sustainable design of coastal buildings, and regeneration of marine ecosystems.
An arid environment refers to specific regions characterized by a severe lack of available water and extremely dry weather conditions. More specifically, arid regions by definition, receive less than 25 centimeters of rain per year. In the immense vastness of arid environments, where extreme climates present significant challenges, the role of water in architecture takes on a new dimension.
For centuries, architects and designers dealing with harsh desert landscapes and the vital necessity of water have invented techniques, technologies, and new structures. Moreover, many creative approaches have been created to harness, collect, and cool water in arid environments.
In parallel to this year's Venice Architecture Biennale, The European Cultural Centre (ECC) presented the sixth edition of its extensive architecture exhibition titled Time Space Existence. The 2023 iteration of the group show draws attention to expressions of sustainability in its numerous forms, ranging from a focus on the environment and urban landscape to the unfolding conversations on innovation, reuse, community, and inclusion. A total of 217 projects by established participants like Snøhetta or MADWORKSHOP and emerging players such as Urban Radicals or ACTA are currently on show through the 26th of November, 2023, at Venice's Palazzo Bembo, Palazzo Mora, and Marinaressa Gardens.
In response to climate change, the installations on show investigate new technologies and construction methods that reduce energy consumption through circular design and develop innovative, organic, and recycled building materials. Participants also address social justice by presenting living solutions envisioned for displaced communities and minorities, while others examine the tensions between the built urban environment and the nature surrounding it to identify opportunities for coexistence.
Concrete, second only to water, is the most consumed material worldwide due to its structural strength, ease of handling, and versatility. Comprised of cement, sand, gravel, and water, it is extensively used in construction projects of various scales. However, even this resilient material can deteriorate over time, necessitating maintenance or, in severe cases, demolition. Abrasion and erosion are factors that can adversely affect the appearance of concrete, remove its protective layer, create a rough surface, and potentially lead to structural issues. These challenges are particularly critical in large and complex construction sites, where any irregularities or unevenness can result in significant losses and complications for architects, engineers, and contractors.
Contemporary architecture's approach to space is fairly linear: enveloping a specified volume within some form of material construct. But if we take a look at humanity's first intentional dwellings, it becomes clear that they were much less premeditated.
Rather than manmade areas to be furnished with pride, our earliest homes were naturally occurring cave lairs that offered hunter-gatherers temporary protection from the elements and potential predators. It wasn't until the appearance of agriculture that our ancestors took permanent, built residences. To this day, troglodytism — or cave living — continues to be connected to ideas of societal disassociation and a hermetic desire to exist outside of orthodox architectural norms. And yet, from Northern China to Western France and Central Turkey, hundreds of millions of people still choose to spend their lives at least partially underground.
The circular economy concept became more defined in 1990 when it appeared in the article Economics of Natural Resources and the Environment, by British economists and environmentalists David W. Pearce and R. Kerry Turner. At the time, the main purpose of the research was to demonstrate that the traditional economy did not incorporate recycling. In this way, the environment assumed a secondary role, just like a simple waste reservoir. Therefore, the circular economy would gain strength as an opposition to the linear (or traditional) economy, in which the production chain motto is “extract, produce and discard”. A model deeply rooted in our economy that has become unsustainable for several reasons, like the depletion of natural resources and the contamination of the environment resulting from production and disposal.
As awareness of water scarcity, water stress and environmental sustainability grows around the world, the concept of "water footprint" is becoming increasingly relevant. Unlike its more popular cousin, "carbon footprint", which focuses on greenhouse gas emissions, the water footprint (WF) provides a holistic view of water used throughout the life cycle of a product, process, or activity. It measures the amount of water consumed (directly and indirectly) and polluted –taking into account different types of water resources– and serves as a valuable tool for companies, policymakers, and individuals to understand and address their water-related impacts. There are even online calculators that measure our individual footprints through simple questions about our homes, appliances and even eating habits.
The UIA World Congress of Architects 2023 is an invitation for architects from around the world to meet in Copenhagen July 2 – 6 to explore and communicate how architecture influences all 17 UN Sustainable Development Goals (SDGs). For more than two years, the Science Track and its international Scientific Committee have been analyzing the various ways in which architecture responds to the SDGs. The work has resulted in the formulation of six science panels: design for Climate Adaptation, design for Rethinking Resources, design for Resilient Communities, design for Health, design for Inclusivity, and design for Partnerships for Change. An international call for papers was sent out in 2022 and 296 of more than 750 submissions from 77 countries have been invited to present at the UIA World Congress of Architects 2023 in Copenhagen. ArchDaily is collaborating with the UIA to share articles pertaining to the six themes to prepare for the opening of the Congress.
In this third feature, we met with co-chairs of Design for Resilient Communities Anna Rubbo, Senior Researcher, Center for Sustainable Urban Development (CSUD), The Climate School, Columbia University, and Juan Du, Professor and Dean of the John H. Daniels Faculty of Architecture, Landscape and Design, University of Toronto.
Almost two decades ago, in the downtown corridor of Columbus, Ohio, the century-old landmarked Lazarus Building underwent an extensive renovation to save the department store and restore it to its former glory. Sixty million dollars went into its restoration and transformation into a retail and office complex. During the construction, workers recycled nearly 5,000 pounds of steel, 2,000 pounds of concrete, and significant amounts of carpeting, ceiling tiles, and various wood- keeping 22,000 pounds of debris out of Ohio’s landfills. They also saved more than $25 million dollars by implementing this rigorous recycling process.
Timber is a natural, renewable material, easy to fabricate, and with low-carbon emissions. As a construction material, however, when put under enough directional force along its grain, sawn timber is structurally unstable, so deemed unsuitable under higher loads. In comparison, the manufacture of cross-laminated timber (CLT) involves simply gluing multiple layers of timber together at right angles. By crossing the direction of the grains, CLT achieves a far higher level of structural rigidity along both axes. CLT boards start with a minimum of three layers but can be strengthened further with the addition of more. Simply put, due to the complex physics involved in the perpendicular lamination, the strength of CLT board is similar to that of reinforced concrete, and has proven performance under seismic forces.
So what’s new? Wood’s been around for long enough now, and we’ve been using it as a building material for centuries. Surely this isn’t the first time someone’s realized it gets stronger the more you use it? Well… as you’d expect, the changing popularity of cross-laminated timber in construction does coincide with a greater understanding and focus on environmental causes, but the relationship hasn’t always been positive.
Architecture is a continually evolving form of human expression influenced by cultural and contextual factors. While many of the problems we face today aren't directly linked to architecture, it has the ability to provide or facilitate solutions to these challenges. This has been evident throughout history, as societal issues have played a significant role in shaping our built environments. For instance, during the Victorian era, the infamous "Great Stink" led to the modernization of London's drainage system and urban layout. Similarly, the 2008 recession gave rise to the sharing economy and coworking spaces. Nowadays, the climate crisis is transforming the way we conceive architecture, seeking to reduce the carbon footprint of buildings and cities to achieve the Paris Agreement objectives. Given this backdrop, what challenges should we expect in the future?
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.
Climate issues have been the main topic of discussions about the future of cities, but they are certainly not new. The warning about human irreversibility on the planet has been part of scientific discourse since the 1980s. Faced with increasingly frequent environmental urgencies, Donna Haraway, in her book Staying with the Trouble: Making Kin in the Chthulucene, suggests a change in attitude on the part of humans to ensure not only partial environmental recovery but the species' survival.
In increasingly denser urban environments, there is a new-found interest in underused spaces as opportunities for further development. Representing up to 25% of cities' land area, rooftops are among the most exciting spatial resources. From sustainable infrastructure and urban farming to social spaces and cultural venues, the article looks into the potential of creating a multi-layered city through the activation of urban rooftops.
When it comes to buildings, there are several factors that contribute to creating something truly luxurious: attention to detail, use of premium, high-quality materials, and unique designs. Lately, the environmental impact of building decisions has also entered heavily into this equation, and the development of a luxury project requires all steps and products to take sustainability into account. At One Za'abeel, the new addition to the Dubai skyline, the careful choice of all solutions, manufacturers and surfaces had a direct influence on the final look and atmosphere of the building, which aims to be an urban landmark and raise the standard of buildings in the UAE.
Environmental issues urgency and increasing temperatures on the planet are nothing new. There are many factors contributing to environmental degradation. However, two can be viewed as representative of critical points in the current world system: plastic and waste disposal, better known as garbage.
The environmental crisis cannot be attributed solely to these two examples. They are used here as examples to mobilize issues involving multiple agents, materials, and diverse methods. These issues lead to devastating consequences, increasingly irreversible.
