The facility will serve students, building operators, building energy auditors, and will be used to support the development of new business ventures in energy efficiency.The Consortium for Building Energy Innovation (CBEI)—formerly the Energy Efficient Buildings Hub—at Philadelphia’s Navy Yard, is a research initiative funded by the Department of Energy and led by Penn State University that seeks to reduce the energy usage of commercial buildings to 50% by 2020. KieranTimberlake, a Philadelphia-based firm located three miles from Navy Yard, was selected by Penn State to renovate a 1940’s Georgian-style brick building to be a living laboratory for advanced energy retrofit technology. Included in the brief was an addition to the building, which evolved into a new stand-alone building across the street on Lot 7R, which aptly became the name of the building. The new 7R building, literally tied to the ground with groundwater-sourced heat pumps, is also formally and tectonically organized around passive solar strategies. A number of daylighting studies drove a re-shape of the building. An initial four-story cube was introduced in Robert A.M. Stern and Associates’ masterplan for the site, but became a long linear east-west oriented low-lying building. This configuration maximizes daylighting while minimizing over-shadowing on the site, establishing a framework for campus growth. 7R is loaded with environmental features including a green roof, a gray water reuse system, integrated daylighting strategies, and geothermal wells. These environmental priorities influenced an approach to building envelope design that balances performance with overriding aesthetics and compositional goals. David Riz, a partner at KieranTimberlake, says the composition of the facade is integral to the siting of the building: “In a large number of our projects, we accentuate the orientation of our buildings with facade treatments.” Brick, chosen for its relationship to a historic Navy Yard context, is utilized as a ‘solar shade,’ opening and closing along the south facade to manage direct heat gain, while eliminating the need for mechanized shades. ‘Rips’ in the brick fabric reveal a transparent glazing system adorned with horizontal sun shade louvers. To the north, the building visually connects to adjacent League Island Park by maximizing glazing along an elevated second floor ‘tree-top’ interior walkway. Arguably the most significant feature of the building envelope is a twin-wall assembly of insulated translucent panels, seen prominently along the length of the north facade, allowing the architects to maximize the level of daylight. David Riz says the panels are notably used both performatively and compositionally, spanning 19’ tall from the plenum to the roof coping: “We wanted to create syncopation in the patterning. We were trying to get a dual read on a long linear building introducing key moments as your eye moves along the building.” The panels are incorporated into the west facade as a primary material to help manage a harsh late-afternoon sun in the large auditorium’s break out space. Riz celebrates the success of the facade in managing a difficult western orientation through diffusing harsh sunlight into a soft glow: “When you’re in the break out space, you simultaneously sense the daylight from the west, a view to the north park, and also a view through the flying brick screen to the south. That’s where it all comes together.” Riz considers the quality of daylight filtering through the building envelope to be one of the project’s greatest strengths: “There are very nice moments as you walk through the building because its so narrow where you experience a simultaneity of the south facade and the north facade: a hint of the brick screen through the classrooms, and bays of transparent panels to the other direction.” KieranTimberlake, who recently received an award for Innovative Research at ACADIA 2015, continues to monitor for thermal performance and storm water analysis. In this regard, the 7R building is a blend between high tech data monitoring, paired with low-tech passive strategies and off-the-shelf products. The project, completed within the last year, will be utilized by Penn State for various research programs.

At six stories high, this is the tallest living Biofilter wall in North America.Neatly contained behind a glass and steel structure is Diamond Schmitt Architects and Nedlaw Living Walls’ latest creation: a 1,370 s.f. vertical living wall assembly, located within a prominent skylit atrium in Vanier Hall, a Social Sciences building on the University of Ottawa’s campus. What appears as a vertical leafy green decorative wall is actually a sophisticated system fully integrated into the building’s air handling system. Contaminated indoor air is drawn through the filtration mechanism—made of plant and root media—where microorganisms consume airborne pollutants as food, breaking them down into water and carbon dioxide. The biofilter effectively cleanses over 13,800 CFM of air. Birgit Siber, Principal at Diamond Schmitt Architects, has incorporated over a dozen large living wall installations in her projects: “One of the things I find so elegant about the initiative of using plants on a large scale within buildings is that it contributes to the indoor environment on so many fronts.” Not only does the wall cleanse dust and odor from the indoor air, but in the atrium, the living wall frames the school’s collaborative social space and functions as an acoustical attenuation device. The living wall can be seen prominently from the exterior, contributing to the school’s identity. The cost of the assembly was determined to be “cost neutral” by the University’s administration, which is seeking a LEED Gold Certification for the building. Biofiltration is a product of research developed at the University of Guelph’s Controlled Environment System Research Facility (1.5 hours west of Toronto), and resulted from an investigation done for the International Space Agency to purify air at a proposed lunar base. Siber teamed with researcher Dr. Alan Darlington, founder of Nedlaw Living Walls, to develop an installation to showcase his research 12 years ago. From this early collaboration between Siber and Darlington, a “no waste” spirit has driven the development of the system, which continues to evolve through seven built versions. Darlington attributes these developments to an underlying desire to improve building performance, “We’ve done a lot of work to streamline and make this as efficient as possible without losing the aesthetics of this system.” The wall at Vanier Hall is loaded with creative features to close the energy “loop holes” found in traditional building systems. Storm water runoff and HVAC condensation are captured and reused for watering the hydroponic plants, while a sophisticated daylight-integral lighting system limits electricity usage used for plant growth to adjust lighting conditions on the plants. The biofiltration living wall system is scalable, having been deployed by Diamond Schmitt Architects and Nedlaw Living Walls in city halls, offices, and universities. It has been developed in coordination with both new construction and renovation projects. Darlington notes that under ideal conditions, roughly 10 square feet of biofilters can generate enough “virtual” outside air for 5-10 people. Diamond Schmitt Architects currently have two US projects under construction – a mixed use tower in Buffalo, and a stacked sequence of four two-story living walls in an academic building at the University of Michigan in Ann Arbor. Architect Birgit Siber of Diamond Schmitt Architects will be speaking at the upcoming Cities Alive conference in New York City on October 6th on a panel discussion from 10:30am-noon entitled, "Living Walls Biofilters: Design, Operating Costs and Return on Investment."
Fossil fuel dependency is now a thing of the past for this municipality on Colorado's Western Slope. Aspen has just announced that it's only the third city to kick the habit and is fully reliant on renewable energy sources. Earlier this month, the Aspen Times reported that the city had reached the landmark after it signed a contract with electrical energy provider Municipal Energy Agency of Nebraska. As part of this process Aspen swapped coal for wind power to make up for the non-renewable energy deficit with its energy also coming from hydroelectric, solar, and geothermal. Prior to this, Aspen had been running on an estimated 75 to 80 percent renewables. The feat was also able to be realized due to the recent drop in solar energy prices. In fact, the cost of solar energy is predicted to fall further still, dropping below $0.50 per watt in the next few years. Solar energy is not alone in this trend. In what's a good economic indicator of renewable energy's growing popularity, wind power is also much cheaper than it was just a decade ago. This trend toward renewables was likely aided by Obama's carbon regulations which made renewable energy alternatives increasingly competitive against fossil fuel sources such as coal. According to ThinkProgress, "already, more than one-third of American coal plants have been shuttered in the past six years, and the new carbon rules make it quite possible that no new coal plants will ever be built in the United States." “It was a very forward-thinking goal and truly remarkable achievement,” Aspen's Utilities & Environmental Initiatives Director David Hornbacher said. “This means we are powered by the forces of nature, predominately water and wind with a touch of solar and landfill gas. We’ve demonstrated that it is possible. Realistically, we hope we can inspire others to achieve these higher goals” Renewable energy has long since been on Aspen's agenda going back to the 1980s with the Reudi and Maroon Creek hydroelectric projects. Highlighting the accomplishment, former Project Coordinator Will Dolan said Aspen only began working toward its goal of 100 percent renewable energy about a decade ago. Beating Aspen to the 100 percent renewable landmark were Burlington, Vermont and Greensburg, Kansas.
This dying mall in Silicon Valley will be reborn with a 30-acre blanket of green roofs including a vineyard, orchard, and walking trails
Green roofs these days are the new blacktops. And just when you thought they couldn't get any bigger, there are now plans to build a 30-acre park blanketing a mixed-use, $3 billion development in Cupertino, California. Right now, the site is the dying Vallco Shopping Mall. Developers Sand Hill Property bought the mall last year and hired Rafael Viñoly and Olin Landscape Architects to redevelop the 50 acre site. "[Sand Hill] didn’t quite know what they would get when Viñoly traveled to their offices in Menlo Park last April for a first-round presentation," wrote the Silicon Valley Business Journal. "While other architects came armed with reams of site plans and renderings, Viñoly had a suitcase. In it was a model of his concept, which he assembled piece by piece, topping it off with the roof park." Renderings show a rolling lush carpet of green capping a 15-block grid of buildings below. But that green is not just a lawn. The rooftop park will feature quite an unusual mix of amenities: a vineyard, close to four miles of trails, an orchard, a playground, as well as lots of oak trees. Plans also include 800 apartments and over 250,000 square feet of retail. There are multiple plazas, a market hall, 2 million square feet of offices, and parking mostly below ground. The highest point in the development would top out at seven stories. "To secure the community buy-in, the developer is going all-out, promising to contribute more than $40 million to build a new K-5 elementary school, replace portable classrooms and provide an “innovation center” to the Fremont Union High School District, among other goodies," reported the SVBJ.
Always an early adopter of innovative sustainability methods, the city of Rotterdam is considering piloting roads fabricated from recycled plastic. The creators of PlasticRoad wooed the city council with their proposal of an all-plastic road that is quicker to lay and requires less maintenance than asphalt. Construction firm VolkerWessels also claims that the material can withstand greater temperature extremes—from -40 to 176 fahrenheit—can be laid in weeks rather than months, and lasts three times as long. The Netherlands-headquartered conglomerate points out that asphalt generates 3.2 billion pounds of carbon emissions globally on an annual basis, accounting for two percent of all road transportation emissions. Lighter roads that exert less pressure on the ground are a godsend for the low-lying Netherlands, one eighth of which is already submerged below sea level. The hollow design of PlasticRoads makes it easy to install cables and utility pipelines and even channel rainwater. Sections of road can be prefabricated in a factory, reducing on-site construction and ensuing congestion caused by roadworks. “As far as I know we’re the first in the world [to try this],” Rolf Mars, director of VolkerWessels’ roads subdivision, KWS Infra, told The Guardian. “It’s still an idea on paper at the moment; the next stage is to build it and test it in a laboratory to make sure it’s safe in wet and slippery conditions and so on. We’re looking for partners who want to collaborate on a pilot – as well as manufacturers in the plastics industry. We’re thinking of the recycling sector, universities and other knowledge institutions.” Although still at the conception stage, VolkerWessels hopes to lay the first fully recycled thoroughfare within the next three years, and the city of Rotterdam is raring to host the pilot test. “We’re very positive towards developments around PlasticRoad,” said Jaap Peters from the city council engineering bureau. “Rotterdam is a city that is open to experiments and innovative adaptations in practice. We have a ‘street lab’ available where innovations like this can be tested.” The initiative should perhaps be most lauded for its potentially massive-scale, industrial use of waste materials. And while plastic bottles are already widely recycled and repurposed into garden furniture, compost bins, and more plastic bottles, the questions becomes: can used up PlasticRoads be recycled?
Though sustainability remains a primary goal for many AEC industry professionals, its definition is increasingly up for debate. Tried-and-true energy efficiency standards such as LEED and Energy Star are facing competition from other rubrics, including net zero. "LEED was the sustainability measure," said CO Architects' Alex Korter. "It's good, but people looked at it more as a certification. With net zero, you're setting hard performance goals." With his colleague Kevin Kavanagh, Korter will lead a panel on "Net Zero and the Future Facade" at Facades+ LA next week. Korter, Kavanagh, and the panelists—who include ARUP's Russell Fortmeyer, Atelier 10's Emilie Hagen, and Stephane Hoffman from Morrison Hershfield—will dig in to the what and why of net zero, and ask how facade designers and builders can push the envelope on environmental performance. Both Korter and Kavanagh see room for improvement in terms of how facade designers and fabricators address sustainability. "Something that we've talked about—and something that will get us in a bit of trouble—is that we don't think the envelope world has done well in terms of upping performance," said Korter. Part of the problem is the focus on checking boxes for energy certifications, rather than setting concrete goals. Even in the world of net zero, said Kavanagh, "the facade is often looked at as an insulating layer, and is relegated to a high-performance insulating component. Our argument is that if you want to maximize net zero, architects and developers really need to rethink their approach to building. Why are facades trying to get as thin as possible? It makes sense for an Apple Store, but for other buildings, why not a two-foot-thick facade with [integrated mechanicals]?" The logical extension of the critique posed by Korter and Kavanagh is, as Kavanagh put it, "Is it possible for a facade to make a building net zero?" But to get there, the two say, designers and fabricators will need a push as well as a pull. "The way this is really going to happen is that the code tells you to, or the building owner—the person who pays the bill—starts to make it their number one priority," said Korter. "Those are the two ways. We've been dancing in this nebulous time: We could do it, but do we really have to?"

Kentucky ranks 17th in the nation for household food insecurity, according to Feeding America Kentucky's Heartland, a local charity. In West Louisville, where nearly half of residents live in poverty, a nonprofit developer is hoping to change that with the help of some high-profile architects. Seed Capital Kentucky's plan is an OMA-designed “Food Hub” on an abandoned plot of land once used to cut and dry tobacco. Mayor Greg Fischer last year gave them a 24-acre vacant parcel of land in the West End worth $1.2 million for the project, which he called "a green job-generating machine for west Louisville." The project could create about 250 permanent jobs and 270 construction jobs, according to the Louisville Courier-Journal. WDRB first reported last week that the hub's designers include OMA and local firm GBBN Architects. The Fox affiliate reported Seed Capital Kentucky is $1 million into their $20 million fundraising goal, seeking $46 million in total, including future fundraising phases. That money would go to several programs, including a food bank, retailers, and a biodigester that turns organic waste into heat and energy. So far four organizations are formally on board: KHI Foods, Jefferson County Cooperative Extension, Star Distributed Energy, and the Weekly Juicery. The site, at South 30th Street between Muhammad Ali Boulevard and Market Street, is in a USDA-certified food desert. Seed Capital Kentucky founder Stephen Reily hopes the Food Hub will help alleviate hunger and stoke investment in the neighborhood. "Our vision for this project is one that collapses a lot of those middle men and transactions into one place where they can all work together to help create more fresh, regional food and help our region feed itself more sustainably," he told WDRB.
In September the Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH) gathered high-minded designers, developers and engineers for a conference in Shanghai. CTBUH, which often partners with AN on conferences, including our own Facades+ events, invited me to serve as a special media correspondent for the conference, held September 16–19. I spent most of the time conducting video interviews with the symposium guests, which we'll post here on the AN blog as they become available. For now, here' a quick overview of the topics discussed. The theme of this year's conference was “Future Cities: Towards Sustainable Vertical Urbanism.” It was an especially relevant topic given the venue—held in the elegant, SOM-designed Jin Mao Tower, the conference looked for lessons (and warnings) in the kind of supertall, super-dense development that turned the Lujiazui area of Shanghai's Pudong district from farmland into a world financial center in just 20 years. Symposium presenters tackled sustainability from several angles. Matthew Clifford, head of energy and sustainability services for North Asia at JLL, stressed building operation and management is as important as design when it comes to energy use and building performance. Cathy Yang, manager of Taipei 101, recounted how “greening” the 101-story building did not turn a profit until the initiative's sixth year, but then made up for it in just three years. The Taiwanese supertall remains the largest LEED Platinum–certified building in the world. Jianping Gu of Shanghai Tower Construction and Development espoused the benefits of the “stereoscopic” form of his building, which at 2,073 feet is set to become the tallest building in China upon completion next year. “If you compare Shanghai Tower to Taipei 101, Petronas Towers, those were all isolated," Gu said. "There were already two towers in the vicinity when we started. We had to pay particular attention to harmonizing with those buildings. We consider this an issue of sustainability.” But towering, monumental architecture may not be for everyone. David Gianotten, an OMA partner heading the firm's Hong Kong office, told me OMA gets so many briefs seeking “iconic” design that the word has begun to lose its meaning. “If everything's special, then nothing's special,” he said. That debate continued onto the conference floor, where developers discussed how China's third- and fourth-tier cities should embrace the tall building boom—or whether they should at all. On the conference's final day, Mun Summ Wong of Singapore-based WOHA talked about the psychological environment of horizontal cities, and how tall buildings should better embrace the human scale. “The idea is to inject more urban life into the high-rise city,” Wong said. “We introduce horizontal movement in the high-rise building because it changes the dynamic. When you talk to the people next to you in an ordinary high-rise, it is considered rude. But in the street, you talk to people, build relationships and bonds.” Similarly, Yang Wu of the Bund Finance Center warned of the risks of homogeneous skylines. “When I open my eyes in the morning and I am in Shenzhen, I still think I am in Shanghai because they look the same,” he said. “[China is] duplicating buildings and the mistakes of the West. There is focus on building bizarre and tall buildings but ignorance of the connotations–resulting in cold buildings for cold cities. As a developer, I call on architects: you need to have your own independent ideas that bring vitality.” You can read more about the conference on CTBUH's website.

The 2014 European Solar Decathlon has come to an end, and the international student competition to design cutting edge solar houses has produced a winner: Team Rhome of Universitá Degli Studi di Roma TRE. Their house, called Rhome for denCity, received a mark of 840.63 out of 1,000 maximum points, edging out the runner-up proposals by a slim margin. Second place went to Philéas by France's Atlantic Challenge and third place to Prêt-à-Loger by TU Delft. Philéas received a score of 839.75 points, coming in only just short of the victors and first place winners Rhome for denCity. The first place Rhome for denCity house is designed as a top floor apartment in the prototype stage that is meant to be a part of a four-story housing project. The house efficiently uses solar panels to power the house whilst relying on natural ventilation to cool its inhabitants. Its design, albeit modest, is pleasant and the house itself could serve as an outline for future sustainable houses. The European Solar Decathlon also gave out six awards for the winners of certain categories such as architecture and engineering/construction. The Dutch team TU Delft took the award for sustainability and communications with their third place entry: Prêt-à-Loger. France’s Athletic Challenge also won in the category of energy efficiency with their second place entry, Philéas.
Today's facade designers cannot afford to ignore the question of sustainability, and in particular energy efficiency. James O'Callaghan (Eckersley O'Callaghan), William Logan (Israel Berger & Associates), and Will Laufs (LaufsED) sat down with our partners at Enclos during April's facades+ NYC conference to talk about the push and pull between aesthetics and environmental performance in building envelopes. Top AEC professionals will continue the conversation at facades+ Chicago on July 24–25. For more information or to register, visit the conference website. Early Bird registration ends June 29.
Chicago’s plan to revitalize troubled South Side neighborhoods with green infrastructure, urban farming and transit-friendly development is moving ahead. The city’s Plan Commission heard a presentation last week on the Green Healthy Neighborhoods program, which in 2011 announced its attention to lure investment to the Englewood, Woodlawn and Washington Park neighborhoods (read AN’s coverage here). While the urban agriculture component initially grabbed headlines—renderings show an old rail line repurposed as the “New Era Trail,” which would link urban farms and community gardens with a park-like promenade—the wide-ranging proposals also include developing retail clusters around transit nodes and street improvements for bikers and pedestrians. Funding is still up in the air, but the project will seek financing through the department of Housing and Urban Development’s Sustainable Communities Initiative. You can see the full plan here.
A British supermarket once lauded for its ingenuity and pioneering nature is now on the chopping block with a Swedish invader looming. When it was completed, the Greenwich branch of UK Mega-chain Sainsbury's was hailed as a breakthrough in eco-design and shortlisted for a prestigious Stirling Prize. Yet in early March the city council approved plans to demolish the structure in order to pave the way for a new IKEA warehouse outlet. The building was designed by Paul Hinkin during his time at Chetwoods Architects. Upon opening in 1999 it became the country's first retail space to receive an "excellent" BREEAM (roughly the British equivalent of LEED) rating. Design features contributing to this assessment include a reed bed that collects rainwater for use in the store, a liberal hand with recycled materials throughout the interior, and on-site wind turbines. Having since launched his own firm, Hinkin is passionate about preserving his 14 year old creation. Speaking from British sustainable building trade show Ecobuild, he vowed to "fight this until the wrecking ball goes through the roof," and called the decision to demolish "totally and utterly indefensible." Hinkin is not alone in this battle, as a campaign to save the structure has been brewing since November once it appeared that it might be under threat. In late February advocates for preserving the market put in a somewhat audacious bid to English Heritage to have the store listed as a Grade II, the second highest grade the organization bestows upon builds that are "particularly important...and of more than special interest." Approval would make the supermarket the youngest recipient of the honor. In light of the Greenwich Council's rulings these efforts would seem to heretofore have been in vain. Sainsbury's decision to sell the site on the condition that it not be filled by another food retailer essentially seals the fate of a structure that was explicitly designed for that purpose. In an essay written for the UK Green Building Council, Hinkin described bespoke, function-specific structures as a key component of his sustainable architectural philosophy. While they may be sustainable in the short-term, the problems buildings designed along such precepts eventually have in adapting to new programs would appear to make them decidedly unsustainable in the long term. The early success and what appears to be an increasingly likely untimely end of the Greenwich Sainsbury's illustrate the immediate benefits and eventual issues destined to plague this approach.
