Climate Crisis: The Latest Architecture and News

Following an extensive report on the impacts of climate change last year, the second installment of the Intergovernmental Panel on Climate Change (IPCC), the United Nation's body for assessing the science related to climate change, addresses the current and anticipated impacts of climate change on ecosystems, biodiversity, and human communities across the globe, along with action plans on how the natural world and human societies could adapt to these changes before reaching an "irreversible" state.

Affordable housing has become an increasingly dire global issue. Be it rent or homeownership, the unaffordability of homes has been on the rise. A look at U.S. Census data illustrates a sharp decline in homeownership in recent decades. Although Millennials were the most populous generation by 2019, they only contributed to homeownership at a rate of 47.9%. Contrastingly, Gen-X’s homeownership rate stood at 69%, following the silent generation at 77.8%. Trends of generational decline in homeownership are mirrored in other parts of the world, such as in the U.K. where rates have steadily dropped from 71% in 2003 to 64% by 2018. Many experts point to affordability as a large reason for this decline.

When talking about energy efficiency in buildings, it is inevitable to mention thermal insulation. We rarely see it in a finished building and, even in the technical drawings, the insulating layer appears as a thin hatch. But this is an element that is of vital importance, as it acts as a barrier to the flow of heat, hindering the exchange of energy between the interior and the exterior, reducing the amount of heat that escapes in winter and the thermal energy that enters in the summer. In a building with good thermal insulation, there is less need for heating to keep the house at a pleasant temperature, also reducing its carbon footprint. Currently, there are many countries that require a minimum level of thermal insulation for buildings, with increasingly strict parameters. But how should this issue be dealt with in the near future, with the worrying climate crisis forecast?

The concept of upcycling refers to taking an item that would be considered waste and improving it in order to make it useful again, adding value and new functionality to it. This is a common word in several industries, such as fashion and furniture. In civil construction, this concept can also be incorporated, making the waste generated by the industry itself recirculate or even bringing what would be discarded from other industries to be processed and incorporated into constructions. This is the case of transforming agricultural waste into building materials, bringing a new use to discards, reducing the use of raw materials and creating products with excellent characteristics.

African nations are fighting climate change with an 8,000 kilometer long Great Green Wall meant to combat the desertification of the Sahel region, home to over 100 million people. Spanning the entire width of the African continent, the movement aims to restore 100 million hectares of degraded land, sequester 250 million tonnes of carbon and create 10 million jobs in rural Africa by 2030. Stretching from Senegal in the West to Djibouti in the East, the project is the joint effort of 21 African nations that strive to restore the once lush region and protect the livelihoods of local communities.

The Royal Institute of British Architects (RIBA) released a short educational film meant to teach young students aged 13 to 16 about the relationship between climate change and the built environment, exploring notions of sustainable design. The film introduces concepts such as embodied carbon, brownfield, green infrastructure, sustainable mobility and explains ideas such as adaptive reuse, retrofit, and the use of local materials. The scope of this learning resource is to empower young people to think creatively about how to address the climate crisis through design, helping raise a generation well versed in sustainability principles.

The growing consumer demand for transparency—especially around sustainability and environmental practices—has implications for industries from apparel to healthcare products. Mars Inc. recently released a cocoa sourcing map to tackle deforestation and increase accountability, and the Fashion Transparency Index pushes apparel companies to be more forthcoming about their social and environmental efforts.

Now it’s time for the building industry, characterized by a lack of information around the materials and practices used in construction and throughout a building’s lifecycle, to catch up. The cost of inaction is too high to ignore. That’s because buildings account for 39 percent of total global carbon emissions. Traditionally, most carbon reduction efforts in the building sector focus on operational carbon—a building’s everyday energy use, which accounts for roughly 28 percent of emissions. The remaining 11 percent comes from what is often ignored: embodied carbon.

Earlier this month, a series of cities worldwide have revealed various initiatives that would help them better understand the effects of climate change and shape a more environmentally conscious environment. From several American cities creating digital twins to help curb carbon emissions to the city of Brighton mandating bee bricks to foster biodiversity and Central Park becoming a laboratory for studying climate change adaptation in urban parks, cities take on a multidisciplinary and multi-scalar approach to environmental issues.

As temperatures rise across the globe with no sign of slowing down, the parks of the future will be subjected to droughts, flooding, punishing heat, and more abundant snowfall as warmer air is capable of holding more moisture than colder air. (It’s often said the world of the future will be wetter and wilder for that exact reason.)

So how can urban parks harden themselves for the coming decades? The Central Park Conservancy, the Yale School of the Environment, and the Natural Areas Conservancy have teamed up to turn New York City’s most iconic park into a hub for studying climate change adaptation and potential mitigation strategies. The Central Park Climate Lab was announced on January 12 by the conservancy, and the insights gleaned from the program will expand to other parks across New York city and eventually, other parks across the country.

Ethical practice spans all parts of architecture. From intersectionality and labor to the climate crisis, a designer must work with a range of conditions and contexts that inform the built environment and the process of its creation. Across cultures, policies and climates, architecture is as much functional and aesthetic as it is political, social, economic, and ecological. By addressing the ethics of practice, designers can reimagine the discipline's impact and who it serves.

As the effects of climate change intensify across the world, the AEC industry is shifting toward green building to effectively address the climate crisis. In 2020, members of The American Institute of Architects (AIA) overwhelmingly approved a resolution making environmental stewardship the organization’s top priority. Since then, steady progress has been achieved to develop a Climate Action Plan, evolve the Framework for Design Excellence, and increase participation in the 2030 Commitment. The building and construction sector is responsible for 36% of energy consumption, 38% of energy related carbon emissions, and 50% of resource consumption globally. These percentages are expected to double in total footprint by 2060, exacerbating the negative effects of climate change on the environment. The Intergovernmental Panel on Climate Change (IPCC) 2021 Report warns of increasingly extreme heatwaves, droughts and flooding, and a key temperature limit being broken in just over a decade. The world must act fast to avoid these catastrophic events, and decarbonizing the built environment is a major step in the right direction.

Most of the news coming out of the recently completed climate summit in Glasgow was disappointing. Previous summits had ended in similarly dispiriting ways, and COP26 was no exception. It acknowledged the severity of the problem and the urgency of the moment—the need to keep warming to under 1.5 degrees Celsius (some scientists believe it’s already too late to prevent this)—but put off making the hard commitments necessary to actually solve the problem. At the same time, this summit did feel different. There was a sense of urgency in the Glasgow streets, and the world’s attention was undeniably focused on climate change. How this focus eventually translates into action on the political front remains an open question.

But architect Edward Mazria, executive director of Architecture 2030, believes that despite the immense obstacles facing climate activists, the building sector is on the cusp of helping change the course of the planet. He sees genuine reasons for hope and renewed effort. In the wake of the seemingly grim news out of Glasgow, I spoke with him last week about the way forward, how we’ve reached an important inflection point, why energy use tied to buildings has begun to decline globally, and the steps required to fully decarbonize the built environment.

Last week, the Common Council of Ithaca, New York, voted to approve a first-in-the-nation decarbonization plan in which the roughly 6,000 homes and buildings located within the notably “enlightened” lakeside college town will be electrified to meet goals established by the city’s impressively aggressive Green New Deal (GND) plan. That carbon-neutral-by-2030 GND plan was adopted unanimously by the Common Council in June 2019 to “address climate change, economic inequality, and racial injustice,” per the city.

"What if the built environment could be a solution to the climate crisis, rather than part of the problem? What if buildings could act like trees – capturing carbon, purifying the air, and regenerating the environment?" Responding to these questions, Skidmore, Owings & Merrill (SOM) has proposed Urban Sequoia, an architectural concept inspired by the ecosystem at the 2021 UN Climate Change Conference in Glasgow - COP26. The design features “forests of buildings" that isolate carbon and produce biomaterials that create a new ecological and resilient urban environment.
