2040 Vision

A Michigan power utility plans to be totally renewable by 2040
The power utility company serving Traverse City, Michigan, a small city in the north of the state, has decided to shift completely to renewable energy sources. The board of Traverse City Light & Power (TCL&P) decided this month that they would aim to make the shift by 2040, the Traverse City Record Eagle reported last week. Dozens of towns and cities across the country have made similar pledges in the years since President Trump pulled the U.S. out of the 2015 Paris Climate Agreement last year. According to the Record Eagle, Traverse City mayor Jim Carruthers had already announced that all of the city's municipal operations would be renewably powered by 2020. What distinguishes this step is that the utility company is exceeding goals set by the city it serves. Towns and cities rely on utility companies to provide electricity. These utilities, in turn, contract suppliers who generate electricity through a variety of means. When municipalities set green energy goals, that leaves utility companies scrambling to find providers who can fulfill the demand. In the Traverse City case, however, the utility company is deciding to ditch polluting sources before its customers have. The impact may not be enormous—TCL&P serves a region with a population less than 20,000—but it is an example of how utilities could evolve in other areas, and what customers could reasonably demand from their utility companies. As older fossil fuel power plants age out of use, utilities are sometimes confronted with a choice over whether to replace the loss from a similar source or to go after newer, sustainable solutions. The Record Eagle reported that two coal plants that currently supply TCL&P are scheduled to go offline by 2030, and that new wind farms on the Great Lakes could be potential replacements. The article also said that the decision was nearly unanimous among the utility's board, with only one member warning rising costs.

Timberrrrrrrrrrr

Oregon becomes first state to legalize mass timber high rises
Thanks to a recent addendum to Oregon’s building code, the state is the first in the country to allow timber buildings to rise higher than six stories without special consideration. Portland has become something of a hotbed for timber innovation as of late. Carbon12, PATH Architecture’s eight-story glulam and cross-laminated timber (CLT) tower with a steel core, recently became the country’s tallest timber building and was set to be surpassed by LEVER Architecture’s 12-story Framework. Alas, that project was put on hold due to mounting financial difficulties last month, but it seems the precedent that the project achieved in securing a building permit from the State of Oregon and City of Portland will live on. The timber allowance comes courtesy of Oregon’s statewide alternate method (SAM), a state-specific program that allows for alternate building techniques to be used after an advisory council has approved the “technical and scientific facts of the proposed alternate method.” The allowance comes after the International Code Council (ICC)–the nonprofit group that Oregon models its building codes after–established the ICC Ad Hoc Committee on Tall Wood Buildings in 2015 to explore the benefits and challenges of using timber in tall buildings. A Committee Action Hearing was held in April of this year, where the Ad Hoc Committee, made up of code experts, stakeholders, and industry members presented their findings. All 14 of the committee’s suggestions were adopted, introducing standards and best practices for fireproofing, the load-bearing potential of CLT and heavy timber, water resistance, sealing, seismic ratings, and more. Three new building classifications were introduced as a result: Type IV A, timber buildings permitted up to 18 stories and 270 feet tall, Type IV B, timber buildings with a maximum height of 12 stories and 180 feet, and Type IV C, which is permitted to rise nine stories and 85 feet tall at maximum. The shortest of the timber typologies is allowed to use exposed structural timber as an interior finish, whereas the tallest, type A, must enclose all exposed surfaces and include a three-hour fire-resistance rating for the structural elements. “We congratulate the State of Oregon on becoming the first state to provide building code recognition for construction of tall, mass timber buildings,” said American Wood Council President & CEO Robert Glowinski in a statement. “Mass timber is a new category of wood products that will revolutionize how America builds and we’ve seen interest in it continue to grow over the last several years. This action by the Codes Division Administrator helps code officials in Oregon by making provisions consistent throughout the state. In adopting this new method, Oregon has also recognized the significant environmental benefits that accrue from greater wood product use.”

COTE Hanger

AIA to send delegation to Global Climate Action Summit
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.

Super States, Assemble

The Center for Architecture’s latest show imagines the future of the New York region
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.

Texas is a Land of Contrasts

AN travels to West Texas for a photo essay on extraction infrastructure
The stretch of I-20 between Abilene and Midland-Odessa, Texas, passes through what might be the most thoroughly harnessed land in the U.S. Here, the exploitation is complete: Water is pumped from aquifers and used to irrigate corn, cotton, and sorghum fields on the surface, where cattle and poultry are also raised; oil and natural gas are mined from the Permian Basin, the most productive such reservoir in the country, and home, some believe, to trillions more barrels of oil and cubic feet of gas; and thousands of wind farms fill the horizon, the most concentrated part of a statewide infrastructure that nominally churns out 22,637 MW per hour, which is more than any other state. While each of these components is remarkable in itself, the layering of them within a single landscape is sublimely breathtaking. Oil and gas pump jacks and refineries, tanker trains and semi-trucks, water towers and windmills, agricultural fields and center pivot linear irrigation systems, wind turbines and transmission lines create a sci-fi tableau reminiscent of fantasies about terraforming other planets, especially when this scene is compared to the relatively barren desert to the west and south. In this part of West Texas it is possible to see the Anthropocene writ large.

Reservoir Dogs

The hidden story of water’s importance to Texas urbanism
As I drive down into the future lakebed, the terrain on either side of the gravel road becomes haggard and unkempt. Signs of the area’s past as farm and ranchland are evident, but shrubs and gnarled trees have grown high to create a deserted, post-apocalyptic landscape. This is the future site of Lower Bois d’Arc Creek Reservoir, a 16,600-acre lake soon to be constructed in rural Fannin County that will provide water to the North Texas Municipal Water District (NTMWD), serving Dallas suburbs in Collin, Dallas, Kaufman, Rockwall, and Hunt Counties. This lake recently received its permit from the U.S. Army Corps of Engineers, making it the first major reservoir in Texas since Lake Gilmer was constructed in 1999. Reservoirs provide the majority of Texas’s drinking water. Texas has been building reservoirs since 1893 (Lake Austin), with the majority created in the 1940s through the 1960s. There are currently 188 in the state, according to the Texas State Historical Association. In the Dallas area, with the limited availability of river water and an aquifer too low to be practical on a large scale, reservoirs have been the main strategy for providing water to a growing region. During a recent visit to Bonham, the Fannin County seat and nearest town to the proposed lake, a passive acceptance of the forthcoming project was evident among a number of residents. There are those who oppose it, most notably the landowners whose land will soon be flooded. However, in rural unincorporated areas, there are few options for organized resistance when a powerful water authority decides to plant a reservoir in your backyard. Yet the impact on Fannin County extends beyond the boundaries of the lake itself. The NTMWD is required to mitigate the habitat destruction caused by the new reservoir by creating new habitat nearby. Thus, an area slightly larger than the reservoir has been purchased to this end. In total, 33,441 acres of private land has been appropriated from local landowners (5 percent of Fannin County). This situation in Fannin County magnifies a common but overlooked tension in the field. Despite the extreme impact, large-scale water infrastructure is strangely absent from the architectural conversation. Architects employ water conservation and collect stormwater at a building scale, but, like most, take the availability of water for granted. They know their project simply has to tap into the existing water main in the adjacent street. Yet the construction of buildings is an extremely water-intensive process, regardless of the water-efficient fixtures they specify. A significant amount of water is used during the production of concrete, with yet more added at the building site. To complete the curing process, concrete requires approximately one pound of water for every three pounds of concrete. Unfortunately, little data is available for water use in construction sites in the U.S. Furthermore, under current infrastructural constraints, cities have no capacity to provide the resources for their own sustenance. Most cities do not generate power or harvest their drinking water within their boundaries. In light of this, cities can be seen as having a parasitic relationship with their surrounding rural areas. The ugly and unpleasant realities of power generation are located far out of sight of the cities themselves, and the inundation of private land for drinking water is undertaken in rural areas because, after all, they have plenty of land. This leeching of resources from the countryside enables cities to exist, but it is a reality that the design profession should begin to address. In February 2018, the residents of the NTMWD used an average of just under 3,000 gallons per capita. A few months earlier, in August 2017, the water use was approximately 6,200 gallons per capita, which equates to 200 gallons per day per resident. Watering St. Augustine lawns accounts for much of that summertime use in this suburban water district. While the NTMWD champions the new reservoir as critical to its supplies, it will only meet the demand for the year 2022 through 2040, a span of 18 years. At that point, additional reservoirs will be required. While Texas is a large state, land is still a finite resource, and new prime reservoir locations are very limited. Climate change also poses problems for the continued reliance on reservoirs. Record-breaking drought in 2011 meant nearly all the reservoirs were significantly below capacity, with some municipalities enacting mandatory water conservation measures. Future droughts will be harsher, posing severe challenges to water provision. As architects strive to address the challenges of building in our current environment, a knowledge of the complex and connected relationship of water to development and construction is important. Architects and planners, water officials, and more will need to be creative in solving the complex problem of providing water to future populations. While American cities have not yet had to deal with the scale of catastrophic water shortage that occurred in Cape Town, South Africa, it should give us all pause as a similar situation in North Texas is quite possible.

Fluid Boundaries

How the Rio Grande came to separate the U.S. and Mexico
This article is the fourth in a series that originally appeared in AN's July/August 2018 issue which focuses exclusively on Texas and was guest edited by AGENCY. The rest of the essays will be released in the coming days and examine architecture and practice across the southern border of the United States. In the border metropolis of El Paso-Ciudad Juárez, the power relations of international negotiation are not only performed through the apparatus of control over the movement of bodies, but are also embodied in a concrete architecture that exposes the calculus of separation and asymmetrical infrastructural development between the two countries. In the borderland, the control of water—as territory, commodity, and reproductive agent—produces its physical spaces. While the shared waters of the river and the underground aquifers contribute to the reproductive capacity of land within the desert climate, the infrastructures of water supply and sanitation are material evidence of the socio-spatial injustices and imbalances that structure and reproduce social relations within the border cities. Negotiation The geopolitical history of the river as a border and of the partitioning of its waters is inscribed within the built environment as a thick constructed zone. The international border between the United States and Mexico was defined by the 1848 and 1884 Treaties, which delineated that the border follow the Rio Grande (Rio Bravo del Norte) from El Paso to the Gulf of Mexico. This rendered the border an unstable condition, as its line needed to be redefined by the International Boundary Commission each time floods caused the river to relocate. A treaty in 1933 attempted to “fix” the river by engineering it into a constructed channel. However, this location left several hundred acres of disputed Mexican territory to the north of the river—the result of a violent change in course in 1864. The 1963 Chamizal Agreement relocated the river and the international boundary once again, moving the Rio Grande back to its 1852 survey location. In this highly publicized moment of international diplomacy, the disputed land was “returned” to Mexico, and a new channel was constructed to reroute the Rio Grande north so that both river and international border aligned. The division between the two countries was now emphasized, further asserted by the open lands of the former riverbed on the Juárez side and a new elevated border highway on the U.S. side of the channel. Management The colonization of the U.S. would not have been possible without the massive campaign of dam projects in the early 20th century that commodified the waters of the West and irrigated the farms and settlements of homesteaders. Four dams manage and distribute the Rio Grande waters in the El Paso-Juárez region: Elephant Butte, Caballo, American Diversion, and the International Diversion Dam. Water is distributed according to the 1944 Water Treaty, drawn up when the population of Juárez was less than one-tenth its current size. In 1965, the binational Border Industrialization Program enabled maquiladoras, foreign-owned manufacturing plants, to be located within Mexico’s border zones, and to move materials and products with reduced tariffs and trade barriers. This propelled an influx of new residents who arrived to work in the Juárez border zone maquilas. The treaty, which retains the majority of the river water in the U.S., has not been revised since and contains no provisions for sharing the rapidly depleting Mesilla and Hueco Bolson aquifer waters, which traverse the binational region underground. The division of the river water produces politically charged urban spaces. The U.S. Franklin Canal materializes as a physical barrier within the U.S. border zone, flowing deeply and rapidly in a concrete channel alongside the Rio Grande. In Juárez, the diverted water flows along the Acequia Madre, which takes a diagonal course, traversing some of the city’s main public spaces. This once green irrigation channel and common space is now largely neglected and has deteriorated into a toxic line of sewage and trash. Biopolitics Water is not only scarce in the desert city of Juárez—it is also dangerous. The paper worlds of politics materialize as realities on the ground and in the tissues of bodies. Due to the explosive population growth of Juárez, large portions of the city have been rapidly and often informally constructed, typically without proper municipal sewage or drinking water services. The residents of these informal settlements, known as colonias, rely primarily on truck-supplied water, which has a much higher likelihood of being contaminated and results in high rates of water-borne diseases. Only about a third of the city’s sewage is actually treated.  Some colonias have additionally encroached on the city’s drainage gullies and arroyos, putting residents at further risk during flash flood events. In July 2010, the United Nations General Assembly “explicitly recognized the right to clean drinking water and sanitation as essential to the realization of all human rights.” If this mandate is taken seriously by the binational region of El Paso-Ciudad Juárez, new treaties and agreements will need to be negotiated that address not only the scarcity and distribution of its shared waters, but also the shared responsibility of water rights to citizens on both sides of the border. What remains to be seen is not only what shape these take in terms of political agreements, but also how they will reshape the physical urban spaces of the paired cities.

It's Going Down, We're Yelling Timber

Construction on Framework, the tallest timber tower in the U.S., has stalled
Disappointing news has come out of the woodwork this week: plans for the tallest timber building in North America have been shelved. Framework, a 12-story structure planned for downtown Portland, Oregondesigned by LEVER Architecture, was set to begin construction after receiving a building permit and a $6 million investment from the City of Portland to include 60 units of affordable housing. The developer, project^, said that inflation, escalating construction costs, and fluctuations in the tax credit market are to blame for the sudden hold. Despite massive investment, the project still had not met it’s $29 million fundraising goal as of Monday. The tower was on track to break records as the largest single use of Cross-Laminated Timber (CLT) in the U.S., and would have set an example for possibilities in timber structures. It would surpass the already-built Carbon12an eight-story, mass timber building also in Portland. The research and planning that went into crafting the design for Framework were considered by many to be revolutionary in the field. Anyeley Hallova, a developer with the project, acknowledged the extensive work and collaboration the Framework team has undertaken with both private entities and public agencies since the design process began in 2014. “Although beset with market challenges beyond our control, we are very proud of Framework’s achievements and the new standards we’ve established for the use of CLT in the U.S.,” Hallova said in a statement. The project was also expected to be a building block for the revival of the state’s rural timber industry. Recent political attention has surfaced on the topic as Oregon senators Ron Wyden and Jeff Merkley pushed for a half a million dollar grant last week to be awarded to Oregon State University to study the durability of CLT. The team behind Framework was also able to advance research through a $1.5 million award which it won in the 2015 U.S. Tall Wood Building Prize Competition, sponsored by the U.S. Department of Agriculture.

Grow-Your-Own

Yale University and UN Environment design self-sufficient tiny home
Yale University and Gray Organschi Architecture have designed and built a self-sufficient tiny house for UN Environment and UN Habitat, and the building is on display in UN Plaza in Midtown Manhattan until August 11. The Ecological Living Module contains 215 square feet of occupiable interior space and carves out another 16 square feet for a rear mechanical closet. The unit uses passive lighting and moisture collection, structural cross-laminated timber (CLT), food-growing green walls, and sun-tracking solar panels to shrink both the building’s embodied energy and resource needs. According to UN Environment, housing construction worldwide uses 40 percent of all resources produced every year and accounts for one-third of greenhouse gas emissions (not to mention the conflicts being fought over rapidly dwindling materials like sand). The module was commissioned just in time for the United Nations High-level Political Forum on Sustainable Development, to illustrate the idea that sustainable urbanization can only be accomplished if buildings minimize their contribution to climate change. The Yale Center for Ecosystems in Architecture and Gray Organschi worked together to design and install the module in only four weeks. The building was fabricated partially in New Haven and partially in Brooklyn and assembled on the UN campus amidst heavy security and tight construction restrictions. In order to balance maximum sun exposure with thermal comfort, the module was designed with New York’s specific micro-climate in mind. The dramatically-sloped building is clad in dark cedar planks and is home to two cascading “farm walls”, one on either side, and Gray Organschi claims that in New York the home can produce over 260 servings of vegetables. Plants were used inside as well in the loft area, and a living wall in the upper loft area purifies air for the inhabitants. “Structure was used as finish,” explains Gray Organschi founding principle Alan Organschi. The same pale CLT used to support the building was left exposed inside to create all of the finished surfaces, from countertops to stairs. The timber was sourced from the northeastern U.S. and sequestered more carbon than the effort used to harvest it. The team optimized daylighting in the building by carving strategic cuts into the back and roof. An Integrated Concentrating Solar Facade was installed to both reduce the amount of incoming sunlight and harvest solar power; an array of tiny panels track the sun’s movement and focus light on the minimally-sized solar receivers. The team wanted to build a system that could be assembled with the least amount of effort, and that would use the minimal amount of toxic materials to create. After August 11, the Ecological Living Module will be partially disassembled and brought to San Francisco; the structure was built narrow enough to be towed by truck. After that, the module will be flown out for demonstration in Quito, Ecuador, and then Nairobi, Kenya.

Hold the Line

Army Corps of Engineers proposes swinging sea gates for New York Harbor
The shores of New York and New Jersey are, as Hurricane Sandy demonstrated in 2012, particularly vulnerable to flooding, sea level rise, and extreme weather events. Coastal construction has become more resilient (though some question to what end) and flood prevention ideas both big and small have been floated to protect the area’s shores. Now, the U.S. Army Corps of Engineers has proposed several different approaches to preventing flood surges using gates and berms in and around New York Harbor, and environmentalists are sounding the alarm. The proposals are part of the New York-New Jersey Harbor and Tributaries Coastal Storm Risk Management Feasibility Study, a 2,150-mile survey of the region’s most vulnerable areas. The Corps has put together five schemes—four that use storm barriers, and one “as is” projection—and is soliciting feedback from New York and New Jersey residents with a series of information sessions this week. In designing floodwalls for New York Harbor or the Hudson and East Rivers, the Corps will need to balance ecological concerns with property protection; nonprofit clean water advocacy group Riverkeeper has called the Corps “hard infrastructure” solutions, those that use concrete barriers, detrimental to the health of the harbor and its waterways. The Hudson River is technically a tidal estuary and not a full-fledged river. Salt water from New York Harbor, and in turn the Atlantic Ocean, flows back up through the Hudson and mixes with fresh water from tributaries upstate to create a nutrient-rich environment. If the Corps's plan to install a five-mile-long gate across the harbor’s mouth between Sandy Hook, New Jersey, and Breezy Point in the Rockaways came to pass, Riverkeeper argues that the barrier would slowly cut off nutrients from the harbor and prevent contaminants from washing out into the ocean. “From Day One, these offshore barriers would start to restrict the tidal flow, contaminant and sediment transport, and migration of fish. They would impede the tidal ‘respiration’ of the river. We fear that a slow death would be inflicted on the river and that in time, the barriers would slowly, but surely, strangle the life out of the river as we know it.” The Corps alternative plans include: building berms, dunes, and seawalls across the lower-lying sections of the New York-New Jersey waterfront, with small floodgates across a few waterways; a barrier across the Staten Island-Brooklyn gap spanned by the Verrazzano-Narrows bridge and gates along Jamaica Bay; and targeted berms and seawalls across targeted low-lying coastal areas without any gates. Creating a centralized approach to flood prevention could be more effective than the piece-by-piece method currently being enacted but comes with its own set of risks. If a massive gate were installed to prevent flooding, it would need to be closed more and more frequently as sea levels rise and would increasingly cut off New York and New Jersey’s waterways from the ocean. Planning for a storm that currently has a probability of occurring once every hundred years may be futile as storms of such intensity become increasingly common. Seawalls have been linked to increased erosion, and if water builds up behind the wall, it can be hard to fully drain the affected area. The Corps is looking to identify a scheme to move forward with by the middle of this summer. However, with a possible price tag of $20 billion and several years of construction likely, whether or not the Corps can follow through is unclear. Interested New York and New Jersey residents can learn more at the following information sessions: Monday, July 9th, 3-5 PM and 6-8 PM at the Borough of Manhattan Community College in Tribeca, Richard Harris Terrace (main floor) 199 Chambers St, New York, NY 10007 Tuesday, July 10th, 3-5 PM and 6-8 PM at Rutgers University-Newark Campus, PR Campus Center, 2nd Floor, Essex Room 350 Martin Luther King Jr. Boulevard, Newark, NJ 07102 Wednesday, July 11th, 6-8 PM at the Hudson Valley Community Center in Poughkeepsie, Auditorium Room 110 South Grand Avenue, Poughkeepsie, NY 12603

Passive progressive

New passive ‘house’ guide includes high rises and projects by Handel and FXCollaborative
While sometimes controversial, passive house design techniques have become a standard reference point for some small-scale projects. A new publication by Low Carbon Production from New York titled From Small to Extra Large: Passive House Rising to New Heights expands that scope by presenting 51 new passive projects of a wide range of scales, including high-rise towers. Sendero Verde, a mixed-income development in East Harlem, and The House at Cornell Tech, both designed by Handel Architects, are among the projects published. The Cornell Tech building on Roosevelt Island offers housing for the new academic campus, and the 26-story complex featuring a double height lobby space and ceiling-high windows was once the world’s tallest passive building. The tower made use of specially designed vapor barriers and refrigerant flow systems. Many of the technological solutions are used in Sendero Verde, including a “floor-by-floor” strategy, where each floor has its own condensing unit that is housed in the balconies, creating flexibility in energy use. Sendero Verde incorporates “660 affordable passive house rental units,” community, and retail spaces.  A forest cabin, a country farm, and a panelized home by Barry Price Architecture are also featured in the publication. The 1994-founded design firm has developed standards for comfort, durability, and energy efficiency in their buildings. In a Bearsville, New York cabin, Price used prefabricated roof and wall elements, locally sourced exterior cladding and interior flooring to reduce the building's environmental footprint. Pollution to the rural site was minimized as building elements were manufactured off-site. Three projects by Paul A. Castrucci Architect are described in the publication, including ABC No Rio’s new headquarters in the Lower East Side, which is one of the first passive commercial buildings in the city. The building is included because of its careful attention to air sealing. According to the publication, “the concrete masonry shell was coated with an air sealer on the inside,” and a polyisocyanurate and mineral wool-made secondary air-sealing layer was introduced on the outside. The thermal breaks are essential for reducing energy consumed in regulating the interior temperatures throughout the seasons, according to the passive building philosophy. The report also presents other sustainable buildings by FXCollaborative, Jane Sanders Architect, and CO Adaptive Architecture. Check out this link for the full report.

All the President's Women

Christiana Figueres awarded the Architectural League’s 2018 President’s Medal
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.
