Santa Monica to make all new single-family residential construction net-zero energy starting in 2017
In the near future, students at the Academy for Global Citizenship will learn firsthand how a net-zero building works, as their campus will collect enough solar power to be completely off the grid. Chances are, though, the thing they will remember most distinctly about their unconventional school will be that it included a working farm, complete with a goat.
The Academy for Global Citizenship (AGC) on the Southwest Side of Chicago is already unlike nearly any other K-8 school around. Once it moves out of its now-cramped makeshift space into a brand-new, Studio Gang–designed campus, it will be truly one of a kind.
The charter school, as the name would suggest, was conceived with a focus on global stewardship and was in dire need of a space that better reflected its pedagogy and ambitions. With this charge, Chicago- and New York–based Studio Gang set out to produce a campus that would be a productive space for students, faculty, and the surrounding community. Conceived as a series of flexible “neighborhoods” with indoor and outdoor learning environments, the project is designed without typical circulation space. Rather, students will walk through “Wonder Paths” that wind fluidly though indoors and outdoors. Along these paths students will encounter laboratories, presentation spaces, learning stations, and play areas. A central courtyard will connect all of these diverse programs.The main structure’s design takes cues from industrial building typologies to maximize natural light and solar collection. A sawtooth roofline is set at the optimal angle for solar power, while allowing copious amounts of north light into the learning spaces. Yet the passive and active solar aspects of the project are only part of the school’s sustainability goals. Perhaps the most notable of the school’s amenities is a three-acre urban farm. Along with producing its own power, the school will also produce a portion of its own food. Students will help grow breakfast and lunch for their classmates. The school believes the understanding of agriculture is an important part both of being a global citizen and of creating one’s relationship to food. Anchoring the farm is a greenhouse-barn where classes and presentations can be held for students and the community. “The whole thing is really all about growing a power- and food-conscious community and designing a replicable system that can be used by other schools in the future,” firm founder Jeanne Gang said. Working with Studio Gang on the project are Chicago-based landscape architects site design group, ltd. and New York–based environmental consultants Atelier Ten. The school will be completely one of a kind when finished, but the design is specifically done in such a way that it can be repeated around the world. To do so, prefabricated systems and readily accessible materials are being specified. While Studio Gang is garnering international attention for soaring skyscrapers, it continues to work on smaller-scale projects for socially minded clients. The Academy for Global Citizenship adds to the firm’s list of educational and community projects that includes the award-winning Arcus Center for Social Justice Leadership, the SOS Children’s Villages Lavezzorio Community Center, and the Columbia College Chicago Media Production Center.
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."
