Every year, Earth Day, celebrated on April 22, presents us with an opportunity to contemplate the conditions of our planet and our impact upon it. Generating around 37% of global carbon emissions, the construction industry has an important, often detrimental, role to play, thus placing an increasingly urgent responsibility on architects and builders to devise strategies for reducing this number. Still, the built environment represents the habitat for most of humanity, and so it has the potential to protect and shelter people from the risks posed by the changing climate. Read on to discover a collection of articles delving into the strategies available at urban and architectural scales for mitigating the effects of climate change and minimizing the industry’s impact upon it.
When we think of the word "tropic," the image that typically comes to mind is an exotic space, characterized by perpetual warmth and humidity, with frequent and heavy rainfall nurturing lush vegetation. Throughout history, this tropical climate has been romanticized as a paradise and criticized for potentially fostering weakness due to its perceived clemency.
Thankfully, those judgments and associations have been relegated to the past, paving the way for theoretical and practical projects that outline the advantages and disadvantages of living in a tropical climate. These projects acknowledge the various strategies to enhance human adaptability within these distinctive climatic conditions.
Greenhouses are elegant and ingenious structures that incorporate simplicity in design while creating light-filled spaces that shape indoor climates. With walls and roofs composed mainly of transparent or translucent materials, these structures harness solar energy to create a controlled environment. As advances in materials and environmental management progress, they can seamlessly be integrated into architectural designs, offering innovative solutions that blend functionality with aesthetics. Beyond their original role in plant cultivation, they have evolved into projects that emphasize sustainability, education, and conservation. At their core, they offer experiences of exploration and discovery, showcasing the intricate relationship between sunlight, plants, and indoor environments.
Weaving is not only a technical craft but also a way to design material experiences. Engaging in the process of weaving allows us to structure, communicate, reflect on, and connect with our designs. By experimenting with different fabric structures, we gain insight into how materials behave under tension and compression. This understanding helps us push the boundaries of textiles and their limitations, resulting in designs that stretch and test the properties of the materials.
In architecture, the construction mechanism of weaving centers the shelter to the building process. In this sense, shelter becomes a direct manifestation of material production. Additionally, weaving offers numerous environmental and social benefits by creating shelters that actively engage with materials, tools, technologies, and creative potentials, thereby supporting placemaking.
As the temperature drops in the Northern Hemisphere, cold outdoor spaces are overcome with frost, ice, and snow, and we find ourselves rushing from one heated indoor environment to the next, less willing or less able to stop and appreciate the natural world around us.
Apart from dragging a spruce or fir tree inside and dressing it up in yuletide costume, we tend to leave the real natural world to its own seasonal devices until it reemerges in Spring. However, by inviting the positive effects of plant life into our homes, we can improve both our mental health and the air we breathe by filling them with peace and joy all year round, not just at Christmas.
How is it possible to reduce the energy consumption of our homes? What design, material, and/or technological strategies can be developed to achieve interior comfort while also addressing the climate crisis? While achieving energy efficiency depends, among other factors, on the state of the homes, there are various strategies related to the implementation of renewable energies, air conditioning technologies, and more that can be applied, taking into account government policies, laws, regulations, and standards specific to each region.
Copenhagen-based philanthropic association re:arc institute has announced the cohort of nonprofit organizations, people, and practices they will support throughout 2024. The organization founded in 2022 works at the intersection of climate action and architectural philanthropy, aiming to support the development of solutions that address the root causes and consequences of climate change.
The architectural field often adheres to conventional industry models, either client-based or competition-based, which can perpetuate problematic or extractive motivations. The re:arc institute hopes to rethink the architecture discipline’s potential for addressing social and environmental concerns by providing a blueprint for pioneering philanthropic projects. To do so, they provide funding to nonprofits, individuals, and community-led projects exploring innovative approaches that prioritize planetary well-being. Their focus is on hyper-local, grassroots initiatives that address climate crises with a strong emphasis on the unique needs of specific places and communities.

Architecture is a transdisciplinary field. It incorporates principles and knowledge from several other disciplines to ensure a built structure functions as intended. This fundamentally involves considering the context in which a building is placed, including its immediate surroundings, such as neighboring structures, local biodiversity, and climate. Essentially, architecture only exists within a particular context. When we expand this context to a broader scale, it becomes what we commonly refer to as the "environment."
In an age where humanity's detrimental impact on the environment has become increasingly evident, the concept of rewilding is emerging as a powerful approach to conservation and ecologicalrestoration. In line with growing attention on landscape architecture in recent years, the idea of removing human intervention from our natural surroundings in order to restore a stable equilibrium seems to offer a low-effort, ethereal way to right fundamental climate wrongs. But is a lack of meddling in nature really all there is to rewilding, and how does this relate to architecture and design? We look at key concepts, applications, and examples to find out.
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.
Under the motto "Get Set," the 2022 DDW exhibited more than 50 art and architectural installations to call out designers and communities for a shift from preparation to action facing the challenges of our time. Led by Miriam van der Lubbe, Creative Head of DDW, with Marjan van Aube and Formafantasma as ambassadors, the 21st edition of the Dutch Design Week took place the last week of October in Eindhoven, the Netherlands closing with a Graduation Show of over 200 students of the Design Academy Eindhoven.
Inspiring designers to incorporate innovation and sustainability and familiarize the public with all the technology has to offer, ArchDaily has selected 9 relevant works focused on bio-materials and modular systems. Highlighting ongoing design research, the list underlines projects that reinvent how we deal with nature and the space we live in.
The Zero Carbon policy is intended to create a kind of ecological balance to neutralize greenhouse gas emissions. Several studies report that the construction sector is one of the main responsible for the unbalance in which we find ourselves today, after all, it consumes natural resources on a gigantic scale and still builds buildings that do not collaborate with the maintenance of the environment. Therefore, searching for paths towards a carbon neutral architecture has become fundamental and one of them is learning from past masters, such as the Brazilian architect João Filgueiras Lima, known as Lelé.
The principles of bio-climatic architecture, when applied with an understanding of the surrounding climate and geography, can simultaneously increase a building's efficiency and create a more comfortable living space. Passive measures like solar panels, rainwater and grey water harvesting, openings for natural light, and cross-ventilation are all low-cost, high yield methods of increasing a home's thermal comfort and efficiency and decreasing its carbon footprint.
Nothing is more rational than using the wind, a natural, free, renewable and healthy resource, to improve the thermal comfort of our projects. The awareness of the finiteness of the resources and the demand for the reduction in the energy consumption has removed air-conditioning systems as the protagonist of any project. Architects and engineers are turning to this more passive system to improve thermal comfort. It is evident that there are extreme climates in which there is no escape, or else the use of artificial systems, but in a large part of the terrestrial surface it is possible to provide a pleasant flow of air through the environments by means of passive systems, especially if the actions are considered during the project stage.
This is a highly complex theme, but we have approached some of the concepts exemplifying them with built projects. A series of ventilation systems can help in the projects: natural cross ventilation, natural induced ventilation, chimney effect and evaporative cooling, which combined with the correct use of constructive elements allows improvement in thermal comfort and decrease in energy consumption.
The IAAC (Institute for Advanced Architecture of Catalonia) has developed a series of advanced materials and systems for air conditioning and passive ventilation, allowing homes to reduce interior temperatures up to 5 degrees lower while saving the electricity consumption caused by the traditional air-conditioning. The systems are made from long-lifespan materials, which lower the costs of maintenance in the long-term and can be used as low-cost alternative building technologies.
The projects highlighted are the Breathing Skin, Hydroceramics, Hydromembrane, Morphluid and Soft Robotics - all developed by students of the IAAC's Digital Matter Intelligent Constructions (conducted by Areti Markopoulou). The passive air-conditioning of spaces is investigated using a combination of new materials that mimic organic processes, adaptive structures and Robotics that help regulate temperature and create sustainable micro climates.
