Building technology research center features wood, integrated photovoltaics, and green wall.When John Robinson began formulating a vision for the University of British Columbia's (UBC) Centre for Interactive Research on Sustainability (CIRS), he did not start small. Robinson, who is responsible for integrating academic and operational sustainability at the university's Vancouver campus, dreamed of constructing the most sustainable building in North America, a monument to and testing ground for energy-generating strategies. Invited to join the project in 2001, architects Perkins+Will sought an approach combining passive design and innovative technology. Featuring a facade of locally manufactured wood panels, high performance glazing, solar shading with integrated photovoltaics, and a green wall sunscreen, CIRS is a living laboratory for the research and practice of sustainable design. The initial concept for the building included 22 goals centered on three themes, explained Perkins+Will's Jana Foit. First, CIRS was to have a net positive environmental impact. In addition, the structure was designed to provide an adaptive, healthy, and socially generative workplace for researchers, staff, and students. Third, CIRS would utilize smart building technologies for real-time user feedback and testing. The building envelope was a critical component of the project's overall environmental strategy on both conceptual and practical levels. "The overarching design idea is to communicate sustainability, to make it visible and apparent," said Foit. In terms of pragmatics, the architects focused on reducing heat gain and providing 100 percent daylighting to the interiors. To reduce solar gain, Perkins+Will reduced the window area from the current code of 40 percent maximum to 31 percent. They installed fixed and operable triple-glazed windows on the ground floor, and fixed and operable double-glazed windows above. For cladding, the architects selected Multiple Ply Cedar Panels from locally-developed Silva Panel—one of the first solid wood products designed for rain screen application. "The exterior panels were detailed and designed to be removable, to allow for material testing and research," said Foit. CIRS' two-pronged solar shading program includes a network of fixed shades with integrated photovoltaics and a green wall. The former results in 24,427 kilowatt-hours per year in energy savings. The architects designed the green wall, meanwhile, to protect the west-facing atrium, which lacks a mechanical heating or cooling system. Together with a combination of solid spandrel and vision glass, the living screen achieves 50 percent shade during the warmer months. "The plants are chocolate vines, which lose their leaves in winter, allowing passive heat gain into the building," explained Foit. "In the summer, when the vines are in full bloom, the leaves provide shading for the atrium." In an important sense, the CIRS story did not conclude once construction was complete in 2011. Rather, the proof of CIRS' value as a demonstration tool is in its ongoing operations. The building returns an impressive 600 megawatt-hours of surplus energy to the UBC campus each year—and continues to rack up sustainability prizes, including the Royal Architecture Institute of Canada's 2015 Green Building Award. But perhaps more importantly, thanks to publicly available performance data and a "lessons learned" document compiled by UBC, CIRS has fulfilled Robinson's dream of promoting green design through the construction of a transparent, replicable model.
Though it sits within Shanghai's Jing An Sculpture Park, the building is designed to be more than inhabited art. It recycles rainwater through its green roof and minimizes solar gain using an intelligent building skin, while its oval courtyard pond helps cool the building. Geothermal energy regulates the building's temperature.The museum's collection comprises some 290,000 samples, including a complete, 140-million-year-old skeleton of the dinosaur Mamenchisaurus, and species which cannot be found outside China, such as Yellow River mammoth, giant salamander, giant panda, and Yangtze Alligator. Situated in Shanghai's Cotton Exchange Building since 1956, the natural history museum leaves its historic home for a building with 20 times the exhibition space and a design that looks forward, as well as back through the eons.
A custom concrete curtain wall complements a Singapore university building's unique form.The new Learning Hub at Nanyang Technological University (NTU) in Singapore looks nothing like a typical campus building. School administrators conceived of the facility as the embodiment of a pedagogical sea change, and commissioned London-based Heatherwick Studio to design an iconic structure emphasizing small-group learning and cross-disciplinary interaction. Eschewing perpendicular classrooms and isolated corridors, the architects developed a unique plan in which rounded meeting rooms are arrayed around a central atrium. The Learning Hub's textured concrete facade, punctuated by zig-zags of glazing and pockets of greenery, translates the interior program to the building's exterior, and announces the arrival at NTU of a new way of teaching and learning. The Learning Hub's plan, said project leader Ole Smith, "is basically the whole story of the design." The first challenge was to accommodate a radical departure in the university's mode of instruction. In lieu of traditional master classes, students meet in groups of six with a professor as facilitator. NTU asked Heatherwick Studio to eliminate corners where possible; once the architects observed that the classes would meet at round tables, the next step was to consider rounding the classrooms themselves. Knowing that the windows in the classrooms would need to be small in order to reduce thermal gain, they looked for another way for students to connect with one another and decided upon a central courtyard. "That was part of the brief as well, to enable the students to mix," said Smith. "It's the only building on the campus of 33,000 where they all come together. Art students might have class next to math or engineering students; the hope is that they'll meet up and inspire each other, or develop a business plan together." Singapore's stringent environmental standards necessitated the use of concrete on the building's facade as well as its structure. "That scared us a little," recalled Smith. "In northern Europe we see a lot of Brutalist buildings, and that's not the direction we wanted to go in. We started looking at how we could use the material in a different way." With local concrete contractor LWC, the architects played with pigment, using different colors to signal structure and ornament. In terms of form, they sought a balance between uniqueness and standardization. Heatherwick Studio's 3D modeling specialists came up with a set of 10 curvatures that, distributed across a total of 1,050 facade panels, could be recombined to deliver a unique shape to each classroom—thus streamlining fabrication without introducing obvious repetition. To further camouflage the facade's standardized elements, and to avoid swerving into Brutalist territory, the architects introduced a texture of horizontal bands, spaced, per local code requirements, to be pigeon-proof. In the end, explained Smith, "the panels are all unique because of the system we developed to treat the facade pattern." The system involved applying stripes of glue-like retardant onto the formwork, pouring the concrete, allowing it to set 24 hours, then hosing it down to remove the still-wet material. "We didn't add anything to the facade; we subtracted it," said Smith. To minimize solar gain, Heatherwick Studio introduced narrow bands of glazing around the perimeter of each classroom. Having rejected curved glass as too costly, but wishing to avoid a faceted appearance, the architects arranged the flat panes in a zig-zag pattern. A slight floor-by-floor cantilever further cuts the heat, turning each story into a natural sunshade for those below it. Meanwhile, induction units positioned under the windows passively ventilate the classrooms. Rounded bronze-mesh balconies situated between each classroom wing draw air into and through the courtyard, producing a cross breeze no matter the direction of the wind. The final pin in the Learning Hub's sustainability cap (the building achieved the highest sustainability rating awarded by the government of Singapore) is the hydroponic greenery distributed across the balconies and rooftop garden. For Smith, the ongoing collaboration with concrete fabricator LWC was a crucial element of the Learning Hub's success. The contractor's ingenuity and willingness to work with the architects provided the level of distinction required by the NTU brief. "We spent a lot of time with the consultants working on colors and texture," said Smith. "The concrete has a handmade feel; we're very happy with that. In Europe you pick your facade from a catalogue, but in this situation we were able to design it from scratch."

A temporary installation spruces up the burger stand’s site ahead of its summer openingTwo years ago, Mario Gentile founded Phildelphia-based Shift_Design after being laid off from Peter Marino Architects. With an infant son in tow, he began to design and manufacture a range of systems for outdoor garden environments. The company was part of the GoodCompany incubation program for socially responsible products and will complete a green roof, living wall, and rainwater harvesting system at the Urban Outfitters headquarters at the Philadelphia Navy Yard in September. They are also working with Philadelphia’s Water Department to design new stormwater-collecting planters. Though functional and environmentally minded, the group’s work has a lighthearted appeal for urban environments—something that’s apparent in its newly completed installation at the construction site of Danny Meyer’s first Philadelphia Shake Shack, scheduled to open this summer. When the restaurateur’s Union Square Hospitality Group approached Shift_Design, it was for an interactive riff on Shake Shack’s original ivy-covered burger kiosk in New York. The team landed on a plan combining window boxes and living wall units already manufactured by Shift_Design, plus a set of six custom-designed panels. Fabricated from galvanized steel, the 48-inch-wide by 88-inch-tall panels have a series of ribbons that curve out from the flat surface to create a trellis for climbing ivy. Rows of 24-inch-wide window boxes beneath the custom panels, as well as a centerpiece of living-wall planters, are filled with seasonal and evergreen plants. Because the installation represents the progression from winter to summer, and the food stand’s opening, the temporary back wall is painted with a progression of gray to green blocks. The panels’ ribbons echo this theme with an undulating surface that becomes more pronounced from left to right. Once the stand is open, the plants and planters will be donated to the non-profit organization Rittenhouse Square Flower Market for Children’s Charities. Though the impetus for founding Shift_Design may have been necessity, Gentile said sustainability was on his mind while working with other architects, “but it’s not necessarily at the forefront of their business model,” he said. His past experience at Kieran Timberlake lent itself to the firm’s mission of creating a new breed of retrofitting options for potential garden spaces from walls to roofs. “We started to hone this idea of mass customization, so that’s always been running through the background of my own studies within architecture.” Gentile, industrial designers Chris Mufalli and Thomas Reynolds, and architect Tim Barnes designed the Shake Shack wall, as they do their off-the-shelf products, with a flat-pack design that reduces wasted material. A local machine shop uses CNC laser-cutting tools and ships the flat design to the client directly. Because the garden elements use sheets of 4-by-8-foot or 5-by-10-foot material, Gentile estimated that the designs produce less than 1 percent waste per product. The company has a patent-pending tab system that eliminates tools for the end user, except in one instance: the flat-pack firepit requires a small wrench socket for assembly, but sticking to the low-waste philosophy, the tool does double-duty as a bottle opener.
