The Center for Architecture is collaborating with the Swiss Consulate in New York City, ETH Zurich, and ETH's Singapore outpost to put on a two-day Responsive Cities conference. The first day will focus on “citizen engagement,” that is, how smart cities can be developed with input from their inhabitants from the very beginning of the planning process. Speakers based in New York and Singapore, including Fabien Clavier, Kubi Ackerman, and Mike Aziz, will speak on how technology, data science, and fields like cognitive psychology can be leveraged in making future cities that adapt to the demands of individuals and communities. The second day will be dedicated to the increasingly important problem of rising urban temperatures being brought on by densification, population growth, and global climate change, among other factors. Speakers with backgrounds in everything from urban ecology to policy and law will discuss ways to cool warming cities for a livable future. The conference is free and begins tonight at the Center for Architecture and will continue tomorrow evening at the New School’s John L. Tishman Auditorium.

The city of Boston has unveiled a new vision for protecting the city’s 47 miles of shoreline and has used New York’s SCAPE Landscape Architecture to visualize the vision plan. The plan, "Resilient Boston Harbor," was presented yesterday by Mayor Martin J. Walsh before the Greater Boston Chamber of Commerce. It builds off of the Climate Ready Boston 2070 flood maps and existing district-level plans, coastal resilience neighborhood studies, and the work done under the Imagine Boston 2030 initiative. The ultimate goal is to reinforce Boston’s public spaces, buildings, and infrastructure against the encroach of rising sea levels, the strengthening of storms that climate change will bring, as well as heat waves, drought, and worsening blizzards. With Boston’s population approaching 700,000 for the first time since the 1960s, catastrophic flooding would affect more residents than ever. “We’re not just planning for the next storm we’ll face, we’re planning for the storms the next generation will face,” said Mayor Walsh. “A resilient, climate-ready Boston Harbor presents an opportunity to protect Boston, connect Boston, and enhance Boston, now and for the future. As we enter a new era in our Harbor’s history, Boston can show the world that resilience is not only the ability to survive adversity, but to emerge even stronger than before. That’s the promise of a Resilient Boston.” To meet that ambitious goal, the city has broken down its plan into separate chunks for each neighborhood. The final goal involves opening up public access to the waterfront by raising portions of the coastal landscape, installing strategic flood walls, elevating infrastructure, and flood-proofing buildings, representing a synthesis and consolodation of the prior resiliency work done in the city. In East Boston and Charlestown, Wood Island and Belle Isle will be reinforced to prevent the loss of Boston’s only remaining salt marsh, and the most important transportation corridors will be elevated. The Schrafft Center waterfront will also be redeveloped to incorporate elevated parks and boosted economically by the addition of new mixed-use buildings. In South Boston and Fort Point, Fort Point Channel is currently a major floodway that will need to be redesigned, and a string of parks, dubbed the “Emerald Necklace,” will sop up excess floodwater along Columbia Road. In North End and Downtown, the Harborwalk and Long Wharf are slated for renovations, and the city is planning to kick off a Climate Ready Downtown study to pinpoint further optimizations. Similarly, Boston will launch Climate Ready Dorchester to study improvements to the Dorchester Waterfront. A redesign of Morrissey Boulevard to buffer it against flooding, and the opening of the waterfront along Columbia Point, have already been singled out as potential strategies. The cost won’t be cheap, but Mayor Walsh rationalized the expense as preventative. “In East Boston, we could invest $160 million in resilience or we could do nothing, and expect damages of $480 million," Walsh told the Chamber. "In Charlestown, we could invest $50 million now or pay over $200 million later. In South Boston, we could invest $1 billion or we could pay $19 billion in citywide damages, when Fort Point Channel and Dorchester Bay meet and flood the heart of our city. “We either invest now, or else we pay a much bigger price later. And we’ll pay that price in more than dollars. We’ll pay it in jobs lost, small businesses that never recover, homes destroyed, and families displaced.” The city will start by investing millions at each of the above sites and ten percent of all future capital funding towards resiliency initiatives. Still, the north-of-a-billion-dollar estimates will require funding from Massachusetts, the federal government, and private, non-profit, and philanthropic organizations. Besides hitting the goals outlined in Resilient Boston Harbor, the city is also committed to going completely carbon neutral by 2030.
Exactly one year after Hurricane Harvey touched down in Texas, Gulf Coast oil and gas industries have reportedly been lobbying hard for protection against the rising tides. As Houston residents prepare to go to the ballot over a $2.5 billion resiliency and flood mitigation bond package on August 25, the Texas state government has already approved $3.9 billion to protect oil refineries. Texas Governor Greg Abbott and other state leaders had proposed a $61 billion plan for rebuilding and hardening the state’s coast in November of last year, but at the time, officials in the fiscally conservative state balked at the cost. Texas was far from the only state swamped by a heavy hurricane season last year, and with wildfires raging across the West Coast, lawmakers claimed that disaster relief funding had been stretched thin. The most ambitious portion of the Rebuild Texas plan proposed last year was the “Ike Dike,” a $12 billion series of levees and seawalls along the Gulf Coast that would form a protective “spine.” If the plan were funded, three large barriers would be installed along the Houston-Galveston coast to protect against flooding. Now, as AP reports, while the state is still trying to secure the public funding necessary to build the spine, the aforementioned $3.9 billion will go towards building three smaller seawalls to protect oil and gas infrastructure. That was deliberate on the part of the Texas Land Commissioner’s Office, as Hurricane Harvey knocked out about a quarter of the area’s refining capability. Refineries along the Gulf Coast are responsible for 30 percent of America’s refining capacity. The taxpayer-funded sections will provide a six-mile-long stretch of 19-foot-tall seawalls along Port Arthur on the Texas-Louisiana border, 25 miles of floodwalls around Orange County, and the final swath would protect Freeport. Construction is slated to begin in the next few months and once these disparate projects are complete, they could become part of a larger protection network if the rest of the funding is secured later. Still, the irony of the fossil fuel industry asking for money to protect against the effects of climate change was not lost on advocates and casual observers. “The oil and gas industry is getting a free ride,” Brandt Mannchen of the Houston Sierra Club told AP. “You don’t hear the industry making a peep about paying for any of this and why should they? There’s all this push like, ‘Please Senator Cornyn, Please Senator Cruz, we need money for this and that.’”
A study released by the nonprofit Regional Plan Association (RPA) last week found that temperatures in New York City’s busiest subway stations are soaring and that the average temperatures hover around 94.5 degrees Fahrenheit. Although temperatures climbed past 104 degrees at the Union Square station on 14th Street, solutions are stymied by the design of each station, aging infrastructure, and the trains themselves. The RPA surveyed 10 of the busiest stations in New York and found that the sweltering temperatures were exacerbated by the heatwaves that much of New York (and the world) have been experiencing this summer. The constantly late trains aren’t helping commuters either, as passengers have been forced to wait for longer periods of time on the platforms. Why exactly are these stations so hot? As the Village Voice explains, the city’s busiest stations are often its oldest and their design precludes centralized climate control; this is also the official reason given by the MTA. The trains themselves output a large amount of heat as well, both through their air conditioners as well as braking. Each full train weighs around 350 to 450 tons depending on the make and length, and the kinetic energy required to brake is converted to heat when a train stops at a station. The hottest stations surveyed were where trains idled the longest. The Brooklyn Bridge-City Hall stop in Tribeca was unsurprisingly featured as well, as the 6 train makes its last stop there then idles before departing on its uptown route. When WNYC surveyed 103 of New York’s stations during the July 2015 heatwave, the Brooklyn Bridge stop clocked in at 107 degrees. For its part, the MTA has pledged to keep the trains running more efficiently to reduce the time passengers have to wait on these overheated platforms. While the MTA tests new communication and signal technologies that could improve wait times and braking efficiency, New York City Transit Authority President Andy Byford has pledged that most of the subway system will use communications-based train control by 2030. Still, as the climate warms, these types of heat waves are only going to become more common, and the fixes required to keep the city’s subway stations tolerable are solutions that will require long-term investments on par with the MTA's other sustainability initiatives.
With buildings responsible for about 47 percent of electricity usage in the U.S., making buildings more efficient should be a top priority in combatting climate change. New York City has already pledged to retrofit its older buildings and slash CO2 emissions by 80 percent by 2050, but with the withdrawal of the U.S. from the Paris Climate Agreement, such action has been left to cities and states to undertake voluntarily. At the Global Climate Action Summit in San Francisco this September, businesses, investors, and local and state leaders from across the country will convene to discuss ways to decarbonize the economy and reach a carbon neutral U.S. by 2050. The AIA has announced that it will be sending a delegation headed by President Carl Elefante, FAIA, to represent architects at the summit and come back with a set of scalable best design practices. The AIA members attending will be part of the organization’s sustainability-oriented Committee on the Environment (COTE) and other climate change-related groups. The AIA will also be sponsoring two public events during the summit: Carbon Smart Building Day on September 11 and Climate Heritage Mobilization on September 12 and 13. The summit is meant to in part build momentum for COP24 in December, the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change. Still, even if radical decarbonization guidelines are agreed upon at the summit and adopted by the AIA and business leaders in attendance, such a shift likely wouldn’t be enough to reach the Intergovernmental Panel on Climate Change (IPCC)’s target of limiting global temperature increases to 2 degrees Celcius. The Paris Agreement and temperature targets are only reachable if the world were to produce negative emissions and sequester CO2 on a massive scale, a technology that’s still several years away. Still, the AIA has pledged to continue pursuing its sustainability and environmental health goals, as seen in its recent call for a blanket ban on asbestos in building products after the fracas last week.
The nonprofit, nonpartisan Regional Plan Association (RPA) released its Fourth Regional Plan back in 2017, a 400-page prescription for a variety of problems facing the Tri-State New York metropolitan area. Now through November 3, visitors to the Center for Architecture can explore the RPA’s plans for increasing housing affordability, improving the region’s overburdened public transit, and addressing climate change by 2040. The Future of the New York Metropolitan Region: The Fourth Regional Plan exhibition at the Center breaks down The Fourth Regional Plan into four typologies: core urban areas, suburbs, local downtowns, and regional green spaces. Each section is further broken down to address affordability issues, the failure of policymakers to address problems in those regions, how climate change will impact each area, and how to best improve mass transportation. Both the problems themselves, as well as the RPA’s proposed solutions, are on display. The Four Corridors, an RPA-commissioned initiative that tasked four different architectural firms with reimagining different “corridors” throughout the region, is also on display at The Fourth Regional Plan. Rafi A+U + DLANDstudio proposed a “landscape economic zone” to protect the area’s coastal regions from flooding—a softer, living take on the traditional seawall; Only If + One Architecture proposed creating the Triboro Corridor, an accessible route from Brooklyn to Queens to the Bronx; WORKac wants to turn the Tri-State suburbs into denser, greener versions of themselves and create easy access between smaller towns; and PORT + Range proposed reinvigorating the area’s highlands into ecological buffers with varied natural ecosystems. “RPA’s Fourth Plan is a blueprint for creating a healthier, more sustainable, more equitable region, one with more affordable housing, better and expanded public transit, and a closer connection with nature," said RPA Executive Vice President Juliette Michaelson. "This exhibit provides an opportunity for New Yorkers and regional visitors to explore the Fourth Plan and imagine what our future could look like if we are bold enough to reach for it." Other than the show itself, the Center will host two accompanying programs. Creating More Housing without New Construction will take place on September 14 from 8:00 AM to 10:00 AM, and Designing the Future of the Tri-State Region will be held on October 29 from 6:00 PM to 8:00 PM.
The Continuous City: Fourteen Essays on Architecture and Urbanization Lars Lerup Park Books, 2017 $39.00 Lars Lerup, the Swedish-American designer and writer, has published a new book. The Continuous City (Park Books, 2017) presents his latest thoughts on architecture, cities, and the people who inhabit them by way of 14 disparate but interconnected essays. The handsome volume is bound in a matte cover featuring René Magritte’s painting Panorama Populaire (1926), which depicts buildings, a forest, and a seashore stacked atop each other, the ground plane of each upper level sawed away to reveal the strata beneath. The picture turns out to be a perfect signpost for what lies within, as its suggestion that these (and other) seemingly discrete realms are inextricably linked is precisely the crux of Lerup’s otherwise episodic inquiry. Lerup’s two previous titles—One Million Acres & No Zoning (Architectural Association Publications, 2011) and After the City (MIT Press, 2001)—took on the postindustrial car city as a subject of serious study. They look beyond the European-oriented urbanist’s dismissal of such environments as merely “sprawl” to find and examine the often-surreal juxtapositions embedded within that type of built fabric. Both books show Lerup’s fascination with Houston, where he first moved in 1993 from Berkeley, California, to take the job of dean at the Rice School of Architecture, a position he held until 2009. He is currently a professor there. Houston was to architecture in the 1980s what Dubai is to the field today—a petro-capital spending big money on ambitious development projects without paying much attention to the rules. Lerup’s championing of this subject matter in architectural academia (his has been one voice—there are others) has done much to save the discipline from self-inflicted obsolescence, an observation driven home by the fact that approximately 80 percent of currently existing global urban environments are designed and constructed around the automobile. His leadership also supported and propelled other academics who have done important work in this area, including Rice colleague Albert Pope, whose seminal volume, Ladders (Princeton Architectural Press, 1996), laid the groundwork for serious consideration of the postwar American city, and former Rice assistant professor Keith Krumwiede, whose latest book, Atlas of Another America: An Architectural Fiction (Park Books, 2016), explores speculative futures of suburbia. Another of Lerup’s preoccupations is subjectivity. In the 1970s, during a sabbatical from UC Berkeley, Peter Eisenman invited him to the Institute for Architecture and Urban Studies in New York (Rem Koolhaas was writing Delirious New York just down the hall). Lerup’s design work exhibits ties to that lineage of formal exploration and defamiliarization, but where Eisenman seeks to liberate architecture from the user, Lerup’s ambition has been to explore the problems of the urban inhabitant. For example, he did several years of research with the National Bureau of Standards in Washington, D.C., on how people in nursing homes panic and escape buildings that are on fire. The result was a series of publications compiled into Learning from Fire: A Fire Protection Primer for Architects, composed of a series of hand-drawn comic strips that depict nurses and patients reacting to infernos. In Continuous City, Lerup says hello to the Anthropocene. Quoting from the introduction: “The Anthropocene brings with it the realization that we live in a new (catastrophic) geological era of our own making. This is no longer a squabble between liberty or community, but a need to avert disaster. Lacking easy answers, we now seek opportunities for change, skirting the dark side of the new city, which the earlier books dealt with, to find in architecture a device for positive movement forward.” He argues that conceptual distinctions between urban and suburban, or urban and rural, are no longer productive. “The urban,” he writes, “is inescapable. The city is everywhere.” Lerup’s hunt for constructive examples takes the reader on a journey that spans the globe and delves into the history of human settlement. He establishes links between the plan of Teotihuacán and OMA’s Seattle library, investigates the coexistence of natural and built environments in the work of Roberto Burle Marx, considers the synergies of Herzog & de Meuron’s Miami garage, and worries the uneasy relationship between users’ topological experience and the planner’s topographic approach. His findings are as revelatory as they are perturbing. If humankind is to survive the era of global warming (the Anthropocene’s most threatening result), there remains much more work to be done.
This summer, visitors to Times Square can take in an underwater virtual reality experience, courtesy of the North Carolina-based conceptual artist Mel Chin and technology giant Microsoft. The site-specific mixed-reality public art installation titled Unmoored will come to life from July 11 through September 5. Chin tackles the topic of climate change, imagining a future where melting ice caps cause the city to go underwater. As visitors look through VR goggles, they can see a 'nautical traffic jam' of 3-D modeled ships, each with their own unique identification number and name. Ships move slowly in the city, bumping into each other and buildings, creating waves rendered by realistic animation and sound effects. Visitors can also view Wake, another public artwork by Chin, which “evokes the hull of a shipwreck crossed with the skeletal remains of marine mammals,” beside a sculpture of the 19th century opera singer Jenny Lind. Chin chose New York City as the site for the word because it represents the center of trade, entertainment, and capitalism for the country. Its history is loaded with topics that resonate today, like guns and slavery. The USS Nightingale, which was historically involved with the shipping of slaves, is digitally recreated in the Unmoored experience. The installations are part of an exhibition titled Mel Chin: All Over the Place, presented with the Queens Museum of Art and NYC-based, nonprofit arts organization No Longer Empty in various sites around New York. Times Square visitors can view the show through mobile devices via Unmoored’s mobile app, which is now available for download and use. Check this link for more details.
Architects, planners, and policymakers all gathered for a June 20th dinner at the Architectural League of New York, where they conferred this year’s President’s Medal on Christiana Figueres, former Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC). The President’s Medal is the League’s highest honor and was awarded to Figueres for her role in negotiating the 2015 Paris Agreement; the multi-country accord created voluntary emission limits that were designed to keep global temperature rise under two degrees Celsius above pre-industrial levels. Medal recipients are selected by the League’s President and Board of Directors and recognize those who have had an outsized impact in art, architecture, the environment, urbanism, and design. Ecologist and Manahatta author Eric Sanderson, landscape architect and educator Kate Orff, architect Anna Dyson, Architectural League Executive Director Rosalie Genevro, and League President Billie Tsien were on hand to laud Figueres. “As architects, designers, and builders,” said Tsien as she presented Figueres with the award, “we honor her for offering us a model of action based on moral commitment and hope, and for demonstrating how to act with urgency and boldness to take on the encompassing challenge of our era, and in doing so, to imagine the possibility of a better world.” All of the speakers touched on Figueres’ role in bridging environmental concerns with the built environment, and the League’s role in advocating around climate issues. “Moreover, it’s an incredible moment for the League,” said Kate Orff, “a treasured cultural organization that over the years has laureled artists, architects, planners, and patrons of the city, to pivot to a broader context and honor a champion of the planet itself.” Figueres herself echoed the same sentiment in her acceptance speech. “I happen to think that urban spaces are where the new relationship between nature and society will germinate and thrive. And I also happen to think that this is where a lot of […] societal healing is going to take place.” After stepping down from her UNFCCC role in the summer of 2016, Figueres now works as the Vice-Chair of the Global Covenant of Mayors for Climate and Energy, a coalition of cities and local governments that are combatting climate change through local action. Figueres is also the convener of Mission2020, an initiative to drastically reduce worldwide CO2 emissions, and long-term climate damage, by 2020.
Smart Cities New York (SCNY) is North America’s leading global conference exploring the emerging influence of cities in shaping the future. With the global smart city market expected to grow to $1.6 trillion within the next three years, Smart Cities New York is guided by the idea that smart cities are truly "Powered by People". The conference brings together thought leaders from public and private sectors, academia and NGOs to discuss investments in physical and digital infrastructure, health, education, sustainability, security, mobility, workforce development, and more, to ensure cities are central to advancing and improving urban life in the 21st century and beyond.
The New York Times journalist Thomas Friedman once asked, “Do you know what my favorite renewable fuel is? An ecosystem for innovation.” If you pose the same question to Pavegen founder and CEO Laurence Kemball-Cook, his answer would most likely be: foot traffic. That’s because Kemball-Cook, who is passionate about climate change, believes “technology alone won’t make cities perform more efficiently. It’s about changing behaviors.” To that end, he spent time developing renewable energy solutions in built-up urban environments and ultimately landed on the idea of capturing ambient energy from people and footfall. After testing a series of prototypes, Kemball-Cook jumped in feet first and launched Pavegen, a company that harvests energy and data from foot traffic. Building a complex technological product that operates reliably in all physical conditions isn’t easy, however. City streets are constantly undergoing challenges, from extreme temperature variations to a wide range of forces and impacts, Kemball-Cook explained. “Engineering this versatility into our system has been a big challenge, and it has been a highly iterative process to get to where our design is today,” he said.
How it worksAt its core, Pavegen technology is a multi-functional, custom flooring system that transforms foot traffic into off-grid electricity. As pedestrians walk across the system, the weight from their steps creates a vertical movement in the top surface between 5 and 10 millimeters. Electromagnetic generators below the surface compress, creating a rotary motion which produces 2 to 4 joules of energy per step, or roughly 5 watts of continuous power which can be stored in batteries or deployed locally to power applications such as lighting, sensors, and data transmission. Pavegen’s latest model, the V3, features a unique, triangular configuration that enables the tiles’ connected surface to move as a whole. As a result, Kemball-Cook says the formation enables a generator to be placed under each point of the tiles, which translates into greater energy converted per square foot than previous models—200 times more than initial prototypes, in fact. Further, the size of the triangles and the amount of resistance in the flywheels have been modeled using data on the length, speed, and force of human steps. “We use this information to maximize efficiency, and capture most of the available energy from footfall to produce a steady stream of off-grid energy and data.” Additionally, the Pavegen system is able to connect to a range of mobile devices and building management systems. “As well as energy, our systems also provide data on energy output and can connect to users’ smartphones via low-power Bluetooth beacons,” Kemball-Cook said. “We have an app where people can see how much electrical energy they are generating and convert this into rewards, which also generates valuable relationship data.” Ultimately, strengthening the relationship between people and the environment is what Pavegen is all about. “Our technology enables people to directly engage with clean energy, to increase their understanding of sustainability issues, and to generate useful off-grid energy,” he said. “Pavegen’s combination of physical interactivity and rich data is helping to bring smart cities to life. Forget the Internet of Things, we’re building the Internet of Beings.” [youtube https://www.youtube.com/watch?v=_sby4GR0sD8]
Taking environmental stresses into account when designing a building is typical, but rising tides, heat waves, extreme winds and other climate change-driven conditions present new challenges to building envelopes. Ahead of the upcoming Facades+ conference in New York City on April 19 and 20, AN sat down with Yan Chu of Adamson Associates Architects to discuss what can be done differently. Chu will be presenting as part of a 2:30 PM symposium panel on April 19 titled “Re-evaluating Metrics: Thermal Performance of Building Enclosures and Future Climate Change.” Chu will be joined by Nico Kienzl of Atelier Ten, Ken Kunkel of NC STATE, and Elizabeth Tomlinson of TKDA. Architect’s Newspaper: As climate change becomes more of a factor, how does facade performance need to change? Yan Chu: We design our facades and mechanical systems based on certain climatic data for that region. For New York City, it’s 11 degrees Fahrenheit, 17-mile-per-hour [winds], this is data all of us use every day and know by heart. These numbers have changed very slightly over time. I wonder if there’s a more fundamental rethinking of these basic design functions that we need to make to attack climate change from multiple fronts, beyond just increasing insulation value and decreasing air leakage rate. The data is all based on historical weather data. Every fourth-year cycle when this weather design data comes out, it’s based on the last 20 years, and that’s how [The American Society of Heating, Refrigerating and Air-Conditioning Engineers] ASHRAE derives their design position that you and I and all of the engineers use. If we know that climate change is going to take us to a whole new level of weather conditions, why aren’t we using projected data? What are we actually using as our design basis? There is a whole sector of the design community trying to address resiliency and survivability. We need to find a way to fold that into the design process, and something we need to consider to holistically address climate change in terms of the building envelope. The idea of this panel is to talk about those issues. AN: Are there any big picture things that architects, engineers and designers can do? Chu: The passive house strategy is brilliant because it addresses the performance of the building together with the occupant’s comfort holistically. It really is a holistic way of thinking of design, and moving forward, it’s the kind of mentality we need to adopt. Whether we’re talking about glazed façades or more opaque facade elements, I think the challenge is to get owner incentives to adopt some of these holistic strategies into a larger scale. If we design a building today with the 2014 or 2016 energy code, I know for a fact it’s already not sufficient for when the next code comes. So I think the biggest challenge for us is, how do we incentivize buildings owners, occupants, and designers to address climate change without depending on the building code telling them to do so? The nice thing is that in Europe, the passive house movement is really being brought by the private sector. How can we bring that mentality to the U.S.? Especially for very large projects? AN: What will the impact of climate change be on envelopes? Chu: It depends on the climate and depends on what extreme events we’re being challenged with. On one hand, we have to re-evaluate the average condition; in some parts of the world, the temperature will increase, but in some locations, temperatures will actually decrease. The interesting thing is that certain wall systems have certain advantages in one climate region over another. That idea is limited because design is about flexibility, and you don’t want to prescribe a system that an architect has to design to. The idea of designing to what is the ‘norm’, and what extreme events are, that’s a huge question. Citing one example, flood resistance at storefronts at the ground level. That’s something new that all the architects in New York City are working on, not only specifying how this system works and what test criteria it conforms to, but also, how does it function in a normal day? We’re way in the beginning stage of understanding what that even is. It’s such a new thing that we know we’ll have to go on to full-on testing for this wall system to know what it can accommodate. Whether or not we end up with a standard IGU or something thicker is still something we’re working through. And how does that affect the interior conditions? It’s a big question mark, and it’s only one thing that we’re dealing with. Are we designing for a 50-year building, a 100-year building? The idea of durability has to come into play. That determines what extreme events we’re designing for, and results in a vastly different building. Facades+ in New York City will run from April 19 until April 20, 2018. Registration is still open and available at this link.
