Georgia Tech has approved a 42,000-square-foot project for their campus that aims to pass the Living Building Challenge; construction could begin as soon as this fall. The project began when The Kendeda Fund (an Atlanta-based private foundation) gifted $30 million to Georgia Tech specifically for the creation and operation of a Living Building at the school. (A Living Building has passed the Living Building Challenge's (LBC) stringent standards, which range from energy performance to social equity). The school then hosted an ideas competition and selected a joint design from Atlanta-based Lord Aeck Sargent and Seattle-based The Miller Hull Partnership. The university’s Planning & Design Commission approved the scheme in December and the project has now moved into the design development phase. Despite its approval, the project has presented some challenges due to its lack of programming specifics. A committee of faculty members from Georgia Tech has been working with the design team to refine the program and make sure it addresses the needs of the university. For now, the building program consists of offices, labs, “maker spaces,” classrooms, study spaces, and an auditorium. The program is housed in two rectangular “sheds” joined by a large atrium and featuring a west-facing porch. The structure will be a post and beam system made of locally sourced glue-laminated timbers, adhering to the LBC's strict material requirements. In order to meet the performance standards of a Living Building, the project must also produce 105 percent of the electricity it uses through renewable clean-energy means. The current scheme will use a combination of radiant pipes for heating and cooling, a custom Dedicated Outdoor Air System (DOAS) for dehumidifying the Georgia summer air, and photovoltaic panels on the roof to generate almost 300 kilowatts of electricity. As part of the LBC’s Urban Agriculture requirements, the project must set aside a certain percentage of the site for agriculture initiatives, or 12,577 square feet in this case. Philadelphia-based Andropogon Associates, the landscape architects for the project, is proposing many strategies including pollinator gardens, blueberry orchards, medicinal plants, and edible vines spread across rooftop gardens and surrounding forest to help with water drainage and shading for the building. Lastly, the building will utilize a combination of “foam-flush” composting toilets and a greywater treatment system to recycle wastewater from the building on site for use around the campus. The building is currently expected to begin construction as soon as this fall. The Kendeda Fund has set up a timeline of the project on their website to keep track of its progress through the many design and construction phases.

Bohlin Cywinski Jackson’s Frick Environmental Center (FEC) in Pittsburgh will be publicly unveiled September 10th. The FEC is the first municipally owned, free and public Living Building Challenge targeted facility. The project is also built to LEED Platinum standards. The FEC will act as an environmental education center for an estimated 20,000 students from Pittsburgh public schools, along with thousands of other visitors. Located in the 644-acre Frick Park, the project will provide support spaces, fully equipped classrooms, and offices for the Pittsburgh Parks Conservancy. The FEC will be free and open to the public, and available for event rental by spring 2017. A public “living room” and gallery will welcome visitors to learn about the park’s history, its extensive trails, the building itself. Bohlin Cywinski Jackson collaborated with the City of Pittsburgh and the Pittsburgh Parks Conservancy on the project. The team also worked with more than 1,000 community stakeholders on the design. Along with the new building, other portions of the park will be restored, including historic gatehouses, an alleé, and fountain. To achieve the Living Building Challenge and LEED Platinum standards, the project uses 35% less energy than baseline structures. With a goal of net zero energy and water, the building will also ground-source heat pumps, radiant floors, a photovoltaic array, and a reclaimed water system. All building materials were sourced within 1,200 miles of the site and subcontractors and tradespeople were hired from the region. Bohlin Cywinski Jackson has also had a local office in Pittsburgh for the past 40-years. “The September 10 celebration will give a sampling of the beautiful building and grounds, environmental education programming, and community spirit that the Center will have to offer our city for generations to come,” explained Pittsburgh Parks Conservancy founder and CEO Meg Cheever.
With a “living” skin of bimetallic strips, four HOK architects have won a Chicago Living Building Challenge competition to design an addition for a school on Chicago’s Southwest Side. The 2014 School Annex Design Competition, organized by the Living Building Challenge Collaborative: Chicago (LBCCC), asked entrants to design a new building for overcrowded Eli Whitney Elementary School while meeting the strict environmental standards of the Living Building Challenge, which include omitting a long list of banned building materials. HOK team members Lindy McAra, Justin Warner, Meredith McBride, Olia Miho and Farid Pour fashioned an addition for the school in Little Village (South Lawndale), a predominantly Latino neighborhood on Chicago’s Southwest Side. Architects +Space are working on a master plan for public magnet school under the Green Schoolyards for Healthy Students program. From the winning team’s press release:
An active, “living” exterior skin acts as a shading device and learning tool by changing shape based on the outside temperature. This strategy draws on the principle of bimetallic strips. When the exterior temperature rises, the panels of aluminum and oxidized copper close, thus acting as a shading device. Once the temperature cools, the panels open, which increases the quantity of light coming into the building.Recently the Midwest Offices of the Natural Resources Defense Council (NRDC) became the first project in Chicago to attain Living Building Challenge Petal Certification.

StructureCraft fabricates an orchid-shaped roof that supports vegetation and Living Building Challenge principles.After serving patrons at one of Vancouver’s oldest botanical gardens for nearly 100 years, the VanDusen Gardens Visitors Centre had fallen dangerously into disrepair. Perkins+Will Canada conceived of a new, orchid-shaped center that meets CaGBC’s LEED Platinum ratings, and is the country’s first structure to target the International Living Building Challenge with features like geothermal boreholes, a 75-square meter photovoltaic array, and a timber roof that supports vegetation. To help fabricate the wooden structure to Perkins + Will Canada’s vision, the team contracted StructureCraft, a Vancouver-based design-build studio specializing in timber craftsmanship and structural solutions. Initial designs for the 19,000-square-foot building were delivered to StructureCraft as Rhino files. The uniquely shaped rooftop, which mimics an outline of the indigenous British Columbia orchid, had to be economically fabricated in a way that took net carbon effects into account. Within Rhino plugins—mainly Grasshopper—and with the help of strucutral engineers Fast + Epp, the StructureCraft team sliced the shape of the building into 71 long, curved panels of repeatable geometries. “Each curve is unique, so there’s a different radii for each beam,” said Lucas Epp, a structural engineer who worked on the project. “We optimized the global geometry of the roof so the radii of all the beams were in our fabrication tolerances but still achieved the architect’s desired aesthetic.” Also within Rhino, the team integrated all of the building’s services into each of the panels. Since much of the piping and wiring for other trades like insulation, sprinklers, and electric utilize flexible formats and conduits, modularizing the panels significantly reduced site time from months, to weeks. And to protect the wooden structures, moisture barriers and closed-cell thermal insulation were applied throughout. The parametric model was then imported to Solids modeling software to develop a bespoke fastening system. StructureCraft used jig and table sawing methods to mill panels of Glulam, chosen for its flexibility and strength. Timber battens were affixed as cladding in sizes that were thin enough to naturally accommodate the curves of each panel. Solid timber support columns, carved on StructureCraft’s in-house lathe, taper at both ends to Perkins + Will Canada’s design specifications. Business development engineer Brian Woudstra, who worked on the project, attributed the accuracy of fabrication and the speed of installation to the expansive capabilities of parametric modeling. “We could model every joist, Glulam panel, and ceiling batten to help with conflict detection and feasibility,” he said. “We always prefabricate our projects in our shop, so it’s like a kit of assemblies that all clicks into place.”
