With the recent Metaverse hype, let's address the elephant in the room! As more and more people dance around the subject of weather or not it is harmful for sustainably-conscious architecture designers to utilize the Metaverse, I decided to interview Oliver Lowrie, a Director at Ackroyd Lowrie, an award-winning London-based architecture practice dedicated to building the cities of the future, who is already using this technology to enhance Ackroyd Lowrie’s low-energy designs.
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.
Carbon footprints and CO2 emissions are large topics in our conversations about how we create a more sustainable future. Over time, different companies, organizations, and individuals have pledged to alter their lifestyles and habits to make changes that show that they are dedicated to combating climate change. Especially in the design industry, where buildings generate nearly 40% of annual CO2 emissions broken down between daily operations and construction/demolition, architects have long been feeling the pressure of exploring ways to prove that we are doing our part.
When we take a look at the different scales of emissions, one question commonly occurs- how can we measure the different levels of impact? Is it on us individually to recycle and ensure we never use plastic straws again? Does this even have a major impact? Do more car manufacturers need to find alternates for gasoline-fueled automobiles? Do architects need to only source sustainable materials? What are the actionable steps that truly have an impact?
cove. tool's core mission is to fight climate change by helping architects, engineers, contractors, and developers use data-driven design through automation and cost optimization. Creating a competition premise that called attention to this critical issue was important. With the recently published landmark Intergovernmental Panel on Climate Change's (IPCC) 2021 report that warned of increased extreme heatwaves, droughts, and flooding, as well as a key temperature limit on track to be broken in just over a decade, it further highlighted the urgency. As climate change intensifies, housing stability will be increasingly under threat. These two inextricably linked issues had the potential to spark innovative ideas from the international design community and community-at-large. With the sizeable grand prize of $50k, the goal was to solicit entries from all over the world and help facilitate more conversations about carbon positive, affordable housing that could be replicated in multiple neighborhoods, cities, and countries. Sustainability and affordability are often two topics that are at odds. However, this competition proved that there are creative solutions to complex problems.
Climate change, the scarcity of resources, and urbanisation are hot topics in the building and construction industry. In this context, the importance of sustainability cannot be overemphasised: almost 40% of global CO2 emissions and 36% of global energy usage is associated with building and construction. These figures clearly illustrate the increasing need for more sustainable solutions in the industry.
Companies that play an active role in the building industry have a responsibility to pave the way toward a more sustainable future. This is why partners like Uponor, one of the leading international providers of solutions that move water for buildings and infrastructure, strive to help customers in Europe to choose the perfect solutions for greener building designs.
The climate crisis has reshaped contemporary architecture. Sustainability has become a central guiding force in design, and in turn, architects are rethinking how to build today. For CO Adaptive Architecture, addressing the climate crisis begins with a process oriented practice. Together, Ruth Mandl and Bobby Johnston have created a firm that embodies how a values-based approach can tackle the most pressing issues of our time. The result is elegant and impactful architecture brought to life with poise and finesse.
Nowadays everything is “painted” green. It's green packaging, green technologies, green materials, green cars and, of course, green architecture. A “green wave”, stimulated by the environmental and energy crisis we are facing, with emphasis on climate change and all the consequences linked to global warming. This calamitous situation is confirmed by the second part of the report entitled Climate Change 2022: Impacts, Adaptation and Vulnerability prepared by the Intergovernmental Panel on Climate Change (IPCC) and presented in recent weeks. It reveals that, although adaptation efforts are being observed in all sectors, the progress implemented so far is very low, as the actions taken are not enough.
A carbon neutral building is achieved when the amount of CO2 emissions is balanced by climate-positive initiatives so that the net carbon footprint over time is zero. Considering their unmatched ability to absorb CO2, planting trees is often viewed as the best carbon offsetting solution. But as cities become denser and the amount of available horizontal space for green areas drastically reduces, architects have been forced to explore other approaches. Therefore, to address these climatic challenges and connect people to nature, exterior green walls have become a rising trend in increasingly vertical cities. Even if there is research to claim that these can positively impact the environment, many question if they can actually contribute to a carbon neutral architecture. Although the answer may be quite complex, there seems to be a consensus: green walls can be effective, but only through good design.
Advances in biotechnology and material science are opening new material opportunities, with the potential of fundamentally changing the connection between the built environment and the natural world. Building materials and construction account for 11% of greenhouse gas emissions. The AEC industry can contribute to curbing climate change in the following years, and the re-evaluation of commonplace building materials is one of the most critical steps. Bioengineered materials, which grow, produce energy, self-heal, are the next frontier in biology and material science and potentially a path towards a new kind of architecture. Although innovation in these fields is still far away from mainstream commercial use, it promises to dramatically change the image of the built environment.
It is crucial to consider the future environmental impact of everything we create. Climate change remains high on the global agenda, and every industry must take part in the goal of reaching Net Zero. One of the more challenging industries concerns construction, which plays a vital role in the process of decarbonization and is constantly encountered with challenges to become greener. Therefore, it demands innovative techniques and development of data to find new and sustainable processes. One solution is to introduce and design both cleaner and more efficient materials. Bricks are a good example, as they can be used in building constructions to ensure a circular process and minimize carbon emissions, being an extremely durable material that can be produced with more sustainable techniques.
While circular economy is often discussed in relation to the architectural object through the lens of material recycling, design for disassembly, and material passports, the framework is most fully enacted at the neighbourhood and city scale. Whether it is visions of circular communities that hint at some level of self-sufficiency or policies set in motion by cities, urban-scale projects exemplify the guiding principles of the circular economy, providing a glimpse into what a fully-fledged version of it might look like. The following explores the strategies used in circular urban environments, from architecture and construction materials to energy production, waste management and food production, as well as the processes and operations that govern these designs, providing insights into the conditions that inform circularity.
According to the architect and researcher Patrícia Akinaga, ecological urbanism emerged at the end of the 20th century as a strategy to create a paradigm shift with regard to the design of cities. With this, urban projects should be designed from the potential and limitations of existing natural resources. Unlike other previous movements, in ecological urbanism architecture is not the structuring element of the city — the landscape itself is. In other words, green areas should not only exist to beautify spaces, but as true engineering artifacts with the potential to dampen, retain and treat rainwater, for example. With ecological urbanism, urban design becomes defined by the natural elements intrinsic to its fabric.
As revolutionary as the construction sector may seem nowadays, it currently accounts for nearly 40% of the world’s carbon dioxide emissions, 11% of which are a result of manufacturing building materials such as steel, cement, and glass. Fast forward a couple of years later, after a life-changing global pandemic and indisputable evidences of climate change, CO2 emissions are still on a rise, reaching a historical maximum in 2020 according to the 2020 Global Status Report for Buildings and Construction. Although a lot of progress has been made through technological advancements, design strategies and concepts, and construction processes, there is still a long way to go to reduce carbon emissions to a minimum or almost zero in the development of built environments.
