Architecture encompasses multiple processes, starting with identifying needs and transforming them into habitable structures through thoughtful design. Historically, construction-related processes like resource extraction and end-of-life disposal were often overlooked. However, it is essential to recognize that buildings have a lifecycle with significant impacts on carbon emissions. Emphasizing sustainable practices is vital to minimize our ecological footprint and positively impact the planet.
The world has just witnessed the hottest months in recorded history, and the outlook is far from optimistic. Rising temperatures are driving greater cooling demands, threatening to trigger a vicious cycle of higher electricity use and carbon emissions. In a planet simultaneously facing unprecedented urbanization and a climate crisis, the intersection of building energy efficiency and cooling technologies has never been more crucial.
How do we create buildings that use energy efficiently? Traditionally, efforts to green the built environment have centered on the physical infrastructure, often overlooking the relationships between people and space. The emergence of the technological era has ushered in "Smart Buildings." that employ machine learning and automation. These innovative structures are designed to operate with impressive energy efficiency, however, they are largely disconnected from their occupants. What if buildings could be made smarter and more sustainable by engaging with their occupants?
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."
CPC concrete slabs are based on the technology of "carbon pre-stressed concrete," which originated from a long-term research project conducted by the Zurich University of Applied Sciences Winterthur (ZHAW) and Silidur AG, Andelfingen. These panels are reinforced with thin, pre-stressed carbon strands, allowing them to be three to four times thinner and lighter while maintaining the same load-bearing capacity as traditional reinforced slabs.
The twentieth century marked a definitive shift in the realm of architecture, as the Modernist movement broke from traditional building styles and encouraged experimentation and innovation. With the help of new materials and technologies, these times represent a crucial moment in the history of architecture as both cities and building styles evolved at an unprecedented rate. The structures that stand testament to this day are, however, nearing the age of a hundred years old. Their stark design features are not always embraced by the public, while the functionalist principles often hinder the adaptability of their interior spaces. Given that they also often occupy central positions within the city, there is increasing pressure to demolish these structures and redevelop the area in its entirety.
Sustainable construction certifications can play a crucial role in mitigating climate change by establishing solid criteria to foster ecologically responsible practices in the construction industry. They not only give public visibility to industry-accepted standards and monitor performance, ensuring compliance with regulations, but also stimulate the reduction of negative environmental impacts while rewarding buildings that fulfill strict sustainability standards. By establishing higher levels of excellence in projects and constructions, these certifications influence the evolution of construction codes, training professionals, and even changing corporate strategies.
The architecture and construction industry has undergone a transformation with the integration of various digital tools, now indispensable to the design process. The welcoming of technologies has effectively streamlined operations, enhanced efficiency, and elevated design quality. This digital shift, however, has resulted in a digital divide that goes beyond accessibility to tools and software. It also encompasses the crucial aspect of integrating traditional and indigenous communities into the urban development landscape. Can advancing technology support the growth of vernacular architecture? Can indigenous building practices find a place in the vision for a digitalized future?
In light of the looming climate crisis and the pursuit of sustainability, the concepts of revival and reuse have emerged as crucial strategies in the quest for decarbonization in the architecture industry. These principles preach that creating new structures may be sustainable but encourage architects to minimize their ecological footprint by reactivating and recycling existing resources. This year specifically, innovative projects in line with these themes were displayed as part of the 18th International Architecture Exhibition – La Biennale di Venezia. This world-renowned event’s core purpose is to serve as a platform for architects, designers, and thinkers to collectively reimagine sustainability, decarbonization, resource conservation, and the industry's future.
The built environment is responsible for approximately 42% of annual global CO2 emissions. During a building's lifespan, half of these emissions come from its construction and demolition. To decarbonize architecture and control global emissions, it is important to rethink and reduce the upfront or embodied carbon impacts of demolitions, as well as implement sustainable construction strategies for buildings. Demolitions typically involve dismantling, razing, destroying, or wrecking buildings and structural parts, leading to unsustainable levels of carbon emissions, material depletion, waste, and pollution. These hasty methods of ending the life cycle of a building have negative impacts on the environment, material components, and recycling strategies. Therefore, there is a clear need to re-think the way in which we approach the end of a building or infrastructure project's life towards a more sustainable system of deconstruction.
A type of wetland that provides an incredible carbon-storing capacity. This could be an excellent way to describe a peatland. Found in practically every climate zone in the world, this type of ecosystem is much more than this short description, as it plays an important role in mitigating the climate crisis. But what is it, and how can we use it responsibly?
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 need to reduce the construction industry's carbon footprint and its reliance on virgin natural resources is the most pressing issue facing the sector. It is therefore extremely important to foster innovation that can improve existing building materials and make them environmentally friendly, in order to successfully tackle its sizable carbon footprint and close the material loop.
