Human-driven climate change is threatening the coastal areas that nearly half of the world calls home with rising sea levels and increasingly severe storms. While dams, barriers, dredging, and artificial reefs are sometimes used to address these “forces of nature,” these strategies come with their own drawbacks and, in some cases, significant environmental and ecological impacts. Researchers at MIT’s Self-Assembly Lab, in collaboration with Invena, a Maldivian organization, have proposed a solution that is inspired by nature. Called "Growing Islands," their project uses wave energy to grow sand formations in a way that mimics natural sand accumulation. The hope is that over time, sand can “grow” into new islands, beaches, and barriers that can protect coasts from erosion and save islands like the Maldives that are under threat of disappearing under rising seas. The Growing Islands project uses sand-filled 10-foot-by-10-foot canvas bladders with biodegradable 3D-printed interiors that use energy generated by waves to create new protective sand formations to rebuild beaches and act as “adaptable artificial reefs,” according to the lab’s website. The site goes on to explain: “By harnessing wave forces to accelerate and guide the accumulation of sand in strategic locations, and adapting the placement of the devices to seasonal changes and storm direction, our approach aims to naturally and sustainably reshape sand topographies using the forces of nature.” This past winter, the lab and Invena installed these devices off the Maldivian coast and are collecting data by way of on-the-ground measurements, drones, and satellite imagery. They hope to create an affordable, sustainable solution to protecting island nations—many under threat of disappearance—and coastal towns and cities from encroaching water. More dramatically, the lab also imagines that this process could be leveraged at a larger scale to create entire new islands over time.

In case you’ve missed it, the world is ending. There’s war, displacement, drought, famine, rising seas, sinking cities, faster winds, and a frightening U.N. report suggests irrevocable, possibly humanity-ending results if we can’t reduce greenhouse gas emissions by 100 percent of 2010 levels by 2050. Artist Josh Kline wants to give us a vision of this un-future. In Climate Change: Part One, Kline has transformed Chinatown gallery 47 Canal in Manhattan into a dystopian funhouse, one that reflects and refracts our world—and its possible undoing—back at us for unnerving effect. Through the first door, which features the stars of a mangled American flag peaking through plastered-on sand, you’ll encounter an irregularly shaped green table mounted with a lit vitrine. Against the nearest wall are a series of large, whirring industrial freezers. The tarp floors make a slight, sticky sound underfoot. This table is one of three bearing names that read like euphemisms for the current state of catastrophe capitalism: Transnational Finance, Technological Innovation. In this one, Representative Government, models of various seats of power—the White House, the Reichstag, rendered in Potomac River mud and placed against a satellite photo of Washington, D.C.—slowly drown under the water of melting miniature icebergs. The freezers sustain the chunks of ice just enough that the submergence is painfully slow, taking place over the month-and-a-half of the show's run. As we know, cooling a small space puts out a great deal of heat elsewhere, rendering the gallery quite warm. Other vitrines hold different building typologies, like skyscrapers rising together from an imaginary Manhattan made from all the world's tallest buildings. The Burj Khalifa and the Chrysler Building aren’t in the same city, and there's no iceberg floating and melting in New York's Upper Bay, but you get the idea. The real-life ice may be far away, but water, and the planet, is a continuity. An ice shelf north of Greenland crashing into the sea has implications that reach far further than the Arctic Circle. Through the doors there are other, unenclosed tables, with pink soy wax in the shape of insurance buildings and suburban homes melting down tubes that collect and direct the colored sludge into buckets below. Waste is not hidden, as everything is a system. The doors, each named after a degrees Celsius, with a second parenthetical appellation, are themselves artworks, but also serve their usual purpose. Some rooms, arranged together like a cartoon hallway from a Scooby Doo villain's mansion, can only be entered through a singular door, some an array of doors. They present a false sense of choice, and all lead to the same room, each degree of difference still resulting in the same ruins. The checklist is very clear about origins, at least for some of the more “natural” materials: beach sand from New York City, Shenzhen, and California; desert sand from Texas and the Sahara; steel powder from China. The flags, too, have origin stories, however misleading they might be. We might imagine that the nylon flags desecrated and pasted onto the doors with paint and sand and kelp may represent Germany, the U.S., China, and so on, but they are likely to all be from somewhere else, maybe the same factory, possibly located in none of these countries. To the tentacles of global commerce, borders are long gone. For the refugees of climate disaster and resource wars, the same can’t yet be said. The doors, with their disfigured flags, are meant to represent the dissolution of borders and nations that Kline predicts climate change and its cascading ramifications will bring about. They also represent our willful participation in the house of horrors-style drowning disasters shown in each of the different rooms as we open and close them. Even when faced with three doors, the sense of choice is false: each opens to the same room. Whether our actions raise global average atmospheric temperatures by 2º C (Dutch, Belgian, French, and German flags, all compressed with Sahara Desert sand—a Colonial Chain Reaction) or 3º C (a mashup of the Union Jack and Japanese flags along with kelp and chlorella) or 5º C (American and Russian flags, Potomac River mud), we’ll still find ourselves in too deep, so to speak. Particularly resonant are the banal and domestic scenes. Situated in hermetically sealed versions of the fume hoods from your college chemistry class painted in subdued, aesthetically-pleasing shades of urethane paints with lighting to match, are scenes with dollhouse miniatures, submerged underwater (or really, cyanoacrylate glue and epoxy). They depict sorrily-stocked grocery stores, bland offices, and suburban home interiors, but their titles are not so bland: Erosion, Inundation, and Submersion. Disintegration isn't loss, it’s transformation. Even as rising water washes away the mud of the miniature buildings, that same dirt just is transported elsewhere, but formless. Matter is conserved, even if our environment is not. What once was just becomes something else, and with us gone, who will be there to name it or know the difference anyway? Things happen on scales too large for us to know, or to know to even ask questions about. Kline shows us this, plainly, perhaps even at first propagandistically. In this show alone, the interlocking problems of political power, globalization, financialization, housing, architecture, technology, and climate change are all put on display. But there’s no real call to arms here, just a documentation of the future present. But it does make one have to ask: If this is Climate Change: Part One, what happens in part two?

A group of 17 architecture firms from across the United Kingdom, including Foster + Partners, Zaha Hadid Architects, David Chipperfield Architects, Rogers Stirk Harbour + Partners, released an open letter affirming their commitment to heading off climate change and building a more equitable future for their profession. The planet is in "twin crises," the letter declares, under the heading "UK Architects Declare Climate and Biodiversity Emergency." The full list of founding signatories, all 17 of which are RIBA Stirling Prize winners, is as follows: Alison Brooks Architects; Allford Hall Monaghan Morris, AL_A, Caruso St John Architects, David Chipperfield Architects, dRMM, Feilden Clegg Bradley Studios, Foster + Partners: Haworth Tompkins, Hodder + Partners: Maccreanor Lavington, Michael Wilford, Rogers Stirk Harbour + Partners, Stanton Williams, WilkinsonEyre, Witherford Watson Mann, and Zaha Hadid Architects. Together, the group declared that as the construction and maintenance of buildings account for 40 percent of the world’s energy-derived carbon dioxide production, the architecture and construction industries have a responsibility to change their practices. Their list of demands compiles practical changes that can be taken to mitigate further climate change, and to stem the ecological destruction that comes with new construction and urban sprawl. “For everyone working in the construction industry,” reads the Architects Declare statement, “meeting the needs of our society without breaching the earth’s ecological boundaries will demand a paradigm shift in our behavior. Together with our clients, we will need to commission and design buildings, cities, and infrastructures as indivisible components of a larger, constantly regenerating and self-sustaining system.” Those measures include collaborating with engineers, clients, and contractors throughout the project’s lifecycle to reduce waste: retrofitting older, existing structures instead of razing them for new construction whenever possible; enacting whole-lifecycle carbon and occupancy analysis; minimizing waste; sharing knowledge with colleagues whenever possible on best practices; incentivizing climate change and biodiversity loss mitigation through awards, and many others. At the time of writing, 155 U.K.-based firms had signed the pledge. Earlier this week, Foster + Partners became the first architecture studio in the world to sign on to the Net Zero Carbon Buildings Commitment, meaning that all of their projects would be carbon neutral by 2030.
We do not need more vivid reminders that extreme weather events have the potential to cause appalling loss of life and tremendous property damage. The deadly fires that burned through California in November 2018 followed hard on the heels of a series of hurricanes and floods that wreaked terrible human and economic damage from New York to Houston and Puerto Rico. We are becoming increasingly confident that these extreme events are caused by climate change or, at any rate, that climate change makes them significantly more likely. Recently, the Fourth National Climate Assessment warned that climate change will cost the United States economy hundreds of billions of dollars annually by the end of the century. Increasingly, stakeholders in the construction process are recognizing that buildings need to be designed to withstand the climate conditions of tomorrow as well as today. Naturally, this leads to the question of whether there will be a legal liability when design professionals fail to anticipate the conditions brought about by climate change. There are several avenues by which a design professional might be held liable for failure to adapt to climate change. This article focuses on torts and tort-like duties, which represent a significant risk for design professionals. There are other sources of liability, though. Contracts, statutes, and regulations may all impose particular requirements on architects and engineers. Representations that a project complies with certain standards might also generate litigation. For example, in the wake of the recent California wildfires, the state’s largest utility company was sued by shareholders alleging that it was liable to its shareholders for failing to prevent the fires. Tort law is the body of law that governs our duties to others and the damages that may be due if those duties are violated. It is tort law that generally governs lawsuits over medical malpractice, for example, the injured party claims that they should be compensated because the medical professional’s actions fell below an acceptable standard of care and caused their injury. Under tort law, the design professional owes a duty toward those who could foreseeably be impacted by his or her actions—potentially extending beyond those to whom design professional have contractual duties (such as project owners) to include others, such as users or neighbors. Generally, the duty extends only to those who suffer physical injury to person or property—a tenant whose possessions are damaged by floodwater might have a claim against the design professional; the store across the road that loses business due to a building closure very likely does not.
Tort suits alleging liability for failure to adapt to climate change are unusual, but there are signs that they may be becoming more commonplace.Tort suits alleging liability for failure to adapt to climate change are unusual, but there are signs that they may be becoming more commonplace. An Illinois insurer recently filed (and then dropped) lawsuits alleging that various state municipalities were responsible for payouts because their stormwater management plans did not anticipate increased rainfall that caused flooding. In the wake of Hurricane Katrina, plaintiffs argued, with some success, that it was foreseeable to the US Army Corps of Engineers that a navigation channel would change the local microclimate in ways that exacerbated hurricane damage (St. Bernard Par. Gov't v. United States, 121 Fed. Cl. 687, 721 (2015), rev'd on other grounds, 887 F.3d 1354 (Fed. Cir. 2018), petition for cert. filed, No. 18-359 (Sept. 9, 2018). Tort-like duties may arise in other contexts. Contracts might impose tort-like duties upon design professionals. For example, an architect whose contract specifies a useful life for a building might have a duty to anticipate the effects of climate change during that timeframe. Similarly, statutes can impose tort-like duties and may even be enforceable by private plaintiffs—a not-for-profit was recently found to have the standing to sue an oil company over allegations that its vulnerability to flooding made it incompatible with “good engineering practices” under the Clean Water Act. So, what is the standard of care? Simply put, design professionals have a duty to exercise the care of a reasonable practitioner in the location. Unfortunately, complying with this simple standard can be tricky, and the door is often open for someone to argue after a problem develops that the architect or engineer did not exercise the required level of care. The best way to minimize the chances of that door being opened is to pay careful attention to local best practices.
Compliance with local codes does not insulate the design professionals from liability if their peers are building to a higher standard.Building codes are one potential pitfall. While failure to comply with local building codes can lead to a finding of a per se (i.e., automatic) violation of the design professional’s duty, compliance with local codes does not insulate the design professionals from liability if their peers are building to a higher standard. Design professionals would be well-advised to be aware when local codes are outdated or backward-looking. For example, most states’ building codes do not account for sea-level rise. Similarly, relying on locally available climate data or projections may not be enough to protect the design professional from liability. Today, an architect in New York would have access to well-founded floodplain maps that take into account the potential impacts of climate change. However, this was not always the case. When Hurricane Sandy struck in 2012, many communities’ FEMA maps dated back to 1983. In this situation, it would be more difficult for a design professional to claim that reliance on official floodplain data was reasonable. And this is a significant problem—a 2017 government audit found that 58 percent of FEMA floodplain maps nationally were out-of-date. Further, although New York City benefits from an additional set of FEMA-drawn maps that anticipate the impact of rising sea levels, this is not the case nationally, meaning that even a brand-new floodplain map represents the chance of being hit with a flood in the last century rather than the next one. Practitioners should also be aware of codes governing public development. Future plaintiffs could argue that they are admissible to attack or to buttress expert opinions on the prevailing standard of care for private development. Our practitioner in New York should be aware of the city’s new Climate Resiliency Design Guidelines, which identify climate change risks and appropriate resiliency interventions for city projects—such as raising machinery when building in a potential floodplain. New York is not alone—various other state and local bodies, such as Boston, have developed or are developing similar standards. The Illinois lawsuits discussed above relied, in part, on rainfall predictions in the Chicago Climate Action Plan. Similarly, plaintiffs may argue that various nonbinding standards show prevailing practice. Industry bodies such as the American Society of Civil Engineers are attempting to develop such standards, and the Canadian Engineering Qualifications Board has published standards for engineers adapting to climate change. There is also the risk—as some design professionals have experienced with LEED certification—that undertaking to comply with otherwise nonbinding standards could create legal obligations. Our climate is changing rapidly. Design professionals already have plenty of incentives to make sure that our buildings and infrastructure are ready. A further incentive is that it reduces the risk of tort liability. Larry Dany is a partner at Eversheds Sutherland (US) LLP where he leads the Construction Industry Practice Group in New York City.

Indonesia’s megacity capital has been sinking and snarled by traffic by years, and newly-elected President Joko Widodo has proposed a solution: moving capital operations to another city. It’s important to clarify that Widodo didn’t mean physically moving Jakarta to another location, such as what happened with the town of Kiruna in Sweden, but rather crowning another capital city, or building one from scratch. "We have to find a location that is really minimal in terms of disaster risks," National Development Planning Minister Bambang Brodjonegoro told the Jakarta Globe. "Also, because Indonesia is a maritime nation, the new capital city should be located near the coast, but not necessarily by the sea." Although Jakarta is a booming city of nearly 10 million, it’s also one of the fastest sinking cities in the world, according to the BBC. Groundwater pumping has caused the city to sink by 8 feet in the last 10 years, and some parts of the city are sinking at a rate of nearly 10 inches per year. Half of the city currently sits below sea level, and the rise of the neighboring Java Sea puts the city further at risk of flooding. In 2016, Jakarta was also rated the most traffic-congested city in the world, and it’s estimated that these traffic jams cost up to $7 billion a year in lost productivity. Bambang told the Jakarta Globe that the financial services industry would remain in Jakarta, while Indonesia would implement best practices found in other capital cities, such as Washington, D.C., Canberra in Australia, and Sejong in South Korea, in the new capital. A final location hasn’t been chosen yet, but according to the BBC, three options are on the table. The first is moving the country’s administrative functions to an area just outside of Jakarta, while the second is to rezone a portion of Jakarta and concentrate the government’s offices there. Finally, the option favored by President Widodo is that of building an entirely new capital on a different island. The frontrunner is reportedly Palangkaraya, the current capital of Central Kalimantan, located close to the geographical center of the country. Bambang expects that moving the capital could take up to 10 years, but President Widodo must first pass the legislation through the House of Representatives before the project can begin.
Days after the New York City Council passed the sweeping Climate Mobilization Act, which will impose emission restrictions on buildings over 25,000 square feet, New York's Mayor Bill de Blasio revealed a sweeping “Green New Deal” for the city. The OneNYC 2050 initiative, which would see the city go fully carbon neutral by 2050, tackles climate change through new building codes, glass tower crackdowns, renewable energy requirements, citywide composting, investing in resiliency planning, and by supporting the new congestion pricing scheme. The $14 billion package would, combined with actions taken by the prior administration, reduce carbon emissions from a 2005 baseline level by 40 percent by 2030. A number of steps will help the city government decrease emissions 23 percent from a 2005 baseline. The city’s 50,000 buildings over 25,000 square feet will be retrofitted with more efficient technology, and city-owned buildings will be switched over to all-renewable energy sources in the next five years (the city is currently in talks to build out the infrastructure that would allow them to bring in Canadian hydropower). De Blasio also touted the potential restrictions on new towers with inefficient glass curtain walls. “Now, we’re going to take it another step because part of the problem here is that buildings got built that never should have been built to begin with if we were thinking about the needs of our Earth,” said the Mayor when announcing OneNYC 2050 on Earth Day yesterday. “Some of them you can see right behind us in the background. And so, we are going to introduce legislation to ban the glass and steel skyscrapers that have contributed so much to global warming. They have no place in our city or on our Earth anymore. “If a company wants to build a big skyscraper, they can use a lot of glass if they do all the other things needed to reduce the emissions. But putting up monuments to themselves that harmed our Earth and threatened our future, that will no longer be allowed in New York City.” The mayor went on to ding Hudson Yards in particular, claiming that many of the towers were inefficiently heated or cooled due to their glass envelopes. De Blasio’s aides were quick to point out that the administration wasn’t banning glass as a facade material outright, but that they would be imposing much rigid standards on performance or allowing developers to purchase carbon offsets instead. Mark Chambers, the city's sustainability director, touted SHoP’s American Copper Building for its smart use of high-performance glass. "The reason I’m saying ban is to emphasize the point that if a company came in, a landlord came in with the exact same kind of design that they’ve come in with in too many cases in the last—just few years, it will be rejected and they would not be allowed to build, period. That’s why I say it’s a ban. You literally will not be physically allowed to build the kinds of buildings that have gone up even recently in this town. Now, you know, there’s good examples and Mark pointed out the Copper Building, the buildings that Cornell-Technion are built to much higher standards which is a good example that you can have, you know, a modern skyscraper that works. But honestly even some of the recent ones built in this city don’t meet appropriate standards and those will no longer be allowed." That drew immediate pushback from Hudson Yards’ developer Related Companies, which told Crain's that the neighborhood was designed to meet LEED standards and that its towers were among the city’s most efficient class A office buildings. Other changes the mayor proposed included amending the city’s electrical code, enacting a citywide organics recycling program (composting), and realigning the city’s development goals with the U.N.’s Sustainable Development Goals. Although the New York City Green New Deal was announced with much fanfare on de Blasio’s part, actual details of how these changes would be implemented were sparse. The plan will also have to pass a City Council vote as legislation and may change in the process.
Some of New York’s tallest towers are doing the most harm to the environment. Although buildings larger than 25,000 square feet only represent two percent of the city’s stock, according to the Urban Green Council that minority is responsible for up to half of all building emissions. Now the New York City Council is finally cracking down on the worst offenders, and New York will soon become the first city in the world to constrain large building emissions through hard limits. Yesterday the council passed the eight-bill Climate Mobilization Act, a legislative package that some are comparing to a New Green Deal for New York. The Climate Mobilization Act, which Mayor de Blasio is expected to sign, would set increasingly harsh limits on carbon emissions for buildings over 25,000 square feet beginning in 2024. According to the Urban Green Council, New York City produces 50 million tons of carbon dioxide a year, and buildings account for approximately 67 percent of that—meaning buildings over 25,000 square feet produce 35 percent, or about 13 million tons of carbon dioxide, a year. The legislation covering the affected 50,000 buildings will roll out in phases. This year, an Office of Building Energy and Emissions Performance and an advisory board will be created at the Department of Buildings to both regulate and enforce the new standards. When the law fully takes effect in 2024, emissions from qualifying buildings will need to be reduced 40 percent from 2005 levels by 2030. The Climate Mobilization Act then takes things one step further and requires that these same buildings slash their emissions by 80 percent by 2050. Why are large buildings such energy hogs? Lighting, heating, cooling, and tech requirements, combined with inefficient equipment, all constrained within leaky envelopes, have combined to create a perfect storm of waste. Retrofitting these massive buildings to use or waste less energy is projected to potentially create thousands of jobs for architects, energy modelers, engineers, and construction workers, as everything from inefficient windows to HVAC systems will need to be replaced. For those structures that can’t be brought up to code on schedule, their owners can offset a portion of their emissions by purchasing renewable energy credits. If an owner still isn’t in compliance, they can be hit with an ongoing fine based on their actual emissions versus the cap. The real estate industry had been a vocal opponent of the measure, arguing that it would place an undue burden on both it and tenants. “The overall effect is going to be that an owner is going to think twice before she rents out any space: ‘Is the next tenant I’m renting to going to be an energy hog or not?’” Carl Hum, general counsel for the Real Estate Board of New York (REBNY), told the New York Times. “There’s a clear business case to be made that having a storage facility is a lot better than having a building that’s bustling with businesses and workers and economic activity.” Still, those fears appear unwarranted. Part of the Office of Building Energy and Emissions Performance’s job will be to work with landlords and tenants and issue variances for buildings with higher energy requirements.
New York City’s mayor, Bill de Blasio, took to New York Magazine to lay out an ambitious $10 billion plan to protect Lower Manhattan from the worst effects of climate change. The city will also be advancing $500 million in capital projects right away to beef up the coast with grassy berms, esplanades, sea gates, and by elevating existing infrastructure; but the most surprising measure is an initiative to extend the tip of Manhattan another 500 feet into the East River. Both initiatives are the result of the Lower Manhattan Climate Resilience Study released today as part of the Lower Manhattan Coastal Resiliency (LMCR) project, which is meant to examine the risks and challenges posed by climate change. The study found that by 2050, 37 percent of Lower Manhattan would be susceptible to storm surges, while by 2100 that number would move to 50 percent as sea levels rose six feet. Twenty percent of Lower Manhattan would be vulnerable to daily tidal flooding by that time as well. For an area that holds more than ten percent of New York City’s jobs, and produces ten percent of the city’s gross economic output, flooding on the scale seen during hurricane Sandy would be devastating. The report also identifies heat waves, extreme precipitation events, and the gradual encroachment of groundwater (which would eat away at the neighborhood’s below-ground electrical and transportation infrastructure) as catastrophic threats. After running through a gamut of different flood mitigation approaches, the report advocates extending the shoreline to prevent flood waters from reaching critical buildings and infrastructure sites as the optimal solution. Requiring buildings to implement individual-level flood mitigation measures would result in a piecemeal, non-standardized application, and building hard storm barriers would impede views and access to the waterfront. Mayor de Blasio expects that building into the East River could cost up to $10 billion. “Over the coming years, we will push out the Lower Manhattan coastline as much as 500 feet,” wrote de Blasio in his NY Magazine op-ed, “or up to two city blocks, into the East River, from the Brooklyn Bridge to the Battery. The new land will be higher than the current coast, protecting the neighborhoods from future storms and the higher tides that will threaten its survival in the decades to come. “When we complete the coastal extension, which could cost $10 billion, Lower Manhattan will be secure from rising seas through 2100.” As for funding such an ambitious project, the mayor admitted that the city wouldn’t be able to go it alone, but that President Trump also wouldn’t be willing to contribute. He then called on Democrats to make the project part of their national agenda, to work towards allocating federal funds, and to fast-tracking the extension. Alongside the resiliency study, the city also released the third iteration of their Climate Resiliency Design Guidelines, which architects and planners can use to future-proof their projects. Starting in the spring, the city will begin holding public engagement meetings on all of its resiliency capital projects and the in-progress Financial District and Seaport Climate Resilience Master Plan. The input gathered will help guide the city on which district should receive the first phase of the plan.
“The way we cool our buildings right now is totally wrong,” said Indian architect Monish Siripurapu in a video produced the United Nations' Environment program. The words are bleak, but arguably true; the electricity and hydrofluorocarbons most modern cooling systems demand ironically warm the planet overall while they cool our conditioned spaces. On top of that, with global temperatures rising and worldwide populations growing, demands for cooling are only increasing. More eco-friendly options are urgently needed, and Siripurapu’s New Delhi–based firm Ant Studio has proposed an affordable, scalable, sustainable, and aesthetically appealing solution to the problem of air conditioning. Ant Studio’s mission is to combine “art, nature, and technology,” and its temperature-regulating solution is designed to be as much an art installation as a cooling system. The Beehive, as the system's first iteration is called, was built to ameliorate high-temperature conditions for laborers at the Noida, Uttar Pradesh–based manufacturer Deki Electronics, where generators and other equipment output their own heat, adding to high outdoor temperatures. The Beehive is part of a larger exploration by the firm that leverages terracotta tubes and water as part of a low-energy cooling system. The Beehive, so-named for its honeycomb-like structure, follows an Indian tradition of using earthenware to cool water. “Traditional architecture has so much wisdom,” said Siripurapu. The ancient process has been wholly modernized, with tools such as computational fluid dynamics modeling, as well as the addition of low-energy water pumps and, if needed, electric fans. But instead of using fans with the Beehive installation, Ant Studio’s cooling device was placed right in front of the exhaust vents of the diesel generator near where workers at the factory were active. This was able to drop the “scorching” air being expelled from the generator from 122 degrees Fahrenheit to 97 degrees Fahrenheit, while lowering the overall temperature in the area and reportedly consuming 40 percent less energy than other cooling systems, not to mention using no refrigerants. The cooling system consists of arrays of open terracotta cylindrical cones (designed in such a way to maximize surface area and fired at “mid-level” temperatures to maintain the clay’s ability to absorb moisture from the air) over which water is poured. The water, which adheres to the clay, naturally lowers in temperature due to evaporative cooling, which in turn cools the air passing through the tubes. The water can be recycled throughout the system, requiring only infrequent topping off, and biofilms of microalgae that grow on the clay surfaces can actually aid in air purification, according to the firm. Further, as explained in an informational video from the firm, “all materials are recyclable, reusable, or biodegradable.” While the Beehive at Dika Electronics took on a particular nature-inspired form, the system can be designed in all manner of shapes and sizes, and is inherently modular, making fabrication and assembling on-site simple. The overall hope with the project is to devise a system that is “functional and visually appealing at the same time.” Ant Studio views the cooling systems as a work of sculpture as much as a functional tool. The terracotta cooling systems also could have broader social impact. Besides being a cheap, energy-efficient way to cool factories and public spaces, the craft required to manufacture the tubes creates local employment and skill-building opportunities. It also keeps alive traditional manufacturing techniques that provide a unique, hand-hewn character that industrial cooling systems certainly lack. The clay-based materials also mean a net reduction in embodied energy for these cooling systems. Ant Studio has also proposed a smaller system which they’re calling ETHER, a cooling device for personal use and small spaces that resembles something like a cross between a Dyson fan and an ancient artifact. Ant Studio’s cooling projects were one of the twelve winners of the United Nations’ Asia-Pacific Low Carbon Lifestyles Challenge and have been nominated for the Clean Energy Challenge from What Design Can Do, a “platform” and series of global conferences on design. Nominated teams are given the “opportunity to improve their project” with the final winners to be announced on March 6.
As temperatures continue to plummet in New York, it may not be a total surprise that a giant iceberg has found its way onto the city's streets. Last week, the Garment District Alliance bared its latest interactive art installation, Iceberg, which can be found at the Broadway pedestrian plazas between 37th and 38th Streets. The installation, composed of jagged metallic arches that illuminate and make noises evocative of melting ice as visitors walk through them, was created by ATOMIC3 and Appareil Architecture in collaboration with Jean-Sébastien Côté and Philippe Jean. The work was inspired by actual icebergs and is intended to chronicle the life cycle of a floe, from when it first breaks off the edge of a glacier to when it ultimately melts due to climate change. Part of the motive behind creating the installation was to acknowledge the significance of climate change and global warming, and how they will continue to worsen if people don't make more environmentally-conscious changes to their lifestyles. “This is an astonishing installation that transforms Broadway into a gleaming, interactive experience for pedestrians, while reinforcing an important environmental message,” said Garment District Alliance president Barbara Blair in a statement. Despite the serious message that the piece tries to convey, it appears to be a fun addition to the streetscape, where visitors can playfully interact with the structure, as well as pose for a photo-op. Aside from the arches flashing different colors and emitting loud “drip” noises as people pass under them, the arches make thunderous crashing sounds every so often to indicate an iceberg calving. The energetic spectacle draws in large crowds to the already bustling Garment District, just a few blocks south of Times Square. This isn’t the first time the sculpture has been unveiled to the public; it made its first debut at the 2012 Luminothérapie festival in Montreal. The installation is part of the year-round public art program, “Garment District on the Plazas,” and it will be on view through February 24.
Concrete is perhaps the most prolific and malleable construction material in the world, but our continued dependence on it may be contributing to climate change more than was previously known. The English international affairs think tank Chatham House recently released a report that attributed approximately eight percent of the planet’s annual carbon dioxide emissions to concrete production. The chemical processes used to create cement, burning limestone and clay in a high-temperature kiln and grinding the result, contributes the greatest share of emissions (though the collection of sand, a commonly used aggregate, has its own problems). With the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP24) complete, a “rulebook” for enacting the 2015 Paris Agreement on climate change was agreed on by the 23,000 international delegates present. Even with a guide in place for reducing carbon dioxide emissions, the problem with concrete is that demand is only expected to rise. Currently, the world produces 4.4 billion tons of concrete annually, but that number is expected to rise to over 5.5 billion tons by 2050 as poorer countries rapidly urbanize, according to the Chatham House report. For the concrete industry to fall in line with the Paris Agreement’s targets, emissions will need to fall 16 percent from current levels by 2030. The report argues that target is already an ambitious goal. The production of Portland cement, the kind most widely used today, has remained largely the same since the 1800s. Limestone and clay combine in the kiln to form carbon dioxide and “clinker,” a substrate then mixed with limestone and gypsum to create cement. According to Chatham House, research into “alternative clinker” and low-carbon production methods has thus far been slow going. Less energy-intensive kilns, new types of clinker, carbon capture technology, and switching to renewable energy during the production process will all be necessary “to achieve CO2 reductions consistent with at least a 50 percent chance of limiting the average global temperature increase to 2°C above pre-industrial levels by 2100," according to the BBC. Timber, which sequesters the carbon dioxide absorbed by trees over their life, has slowly but surely made strides in replacing concrete in some projects. High-rise timber buildings have gotten a green light in Oregon, and continued research into carbon-neutral (or negative) projects is continuing apace.
The ongoing threat of climate change and hazardous air quality in urban environments continue to foster sustainable elements within architectural design, ranging from the installation of photovoltaic panels to rainwater harvesting mechanisms. But what if a facade curtain could directly capture CO2? Responding to this challenge, London-based practice ecoLogicStudio, led by Claudio Pasquero and Marco Poletto, unveiled Photo.Synth.Etica at Dublin’s Climate Innovation Summit 2018. The large-scale installation is capable of absorbing two pounds of carbon dioxide per day with the help of an injected algae solution. Photo.Synth.Etica consists of 16 approximately 6.5-by-23-foot bioplastic modules. For the design of the modules, the team interpreted a breadth of data charts stemming from carbon trading transactions, rationalizing them into the welding pattern located between the two layers of bioplastic. Spanning the height of two levels, each module is laced with a coiling void that is injected with micro-algal cultures treated to produce luminescent shades at night. The density of the algae biomass is customizable and can be altered for desired light transparency. The mechanics behind the installation’s air filtration are fairly straightforward: unfiltered air rises from the base of the facade through the cylinder of photoreactive algae, interacting with carbon-consuming microbes. Once captured by the algae, the biomass can be cultivated as a raw material for the production of bioplastics similar to that used for the curtain modules. According to the design team, this particular module “is particularly suitable for retrofit as it is very lightweight, soft, adaptable, and does not require heavy substructures to be installed.” Additionally, ecoLogicStudio has developed higher-end ETFE models of the algae-injected curtain for new construction. Currently, the firm is researching a mass-market prototype that will target the large shed or warehouse typology, with an aim “to cover the large surfaces of malls, distribution centers, and data centers.” Research for the project goes back nearly a decade, including the similarly air-filtering Urban Algae Canopy unveiled at the 2015 Milan Expo. ecoLogicStudio is scaling up their technology with the intention of marketing the new prototypes in 2019.
