Last September, the Council on Tall Buildings and Urban Habitat invited me to serve as the special media correspondent for its Shanghai symposium, entitled Future Cities: Towards Sustainable Vertical Urbanism.
I conducted video interviews with dozens of architects, developers, building managers, and others on topics relevant to tall building design and sustainable urbanism. Among the many designers, engineers and other tall building types I interviewed was Christopher Drew, director of sustainability for Chicago’s Adrian Smith + Gordon Gill Architecture.
The first-ever Los Angeles Facades + conference, organized by The Architect’s Newspaper and Enclos, held in the shadow of Bunker Hill’s glassy towers, showcased the city’s technical and creative talent while introducing participants to the building envelope field’s latest technologies and trends.
Keynote speaker James Carpenter set a sophisticated tone, showing off richly complex work that explores both the “cinematic” and “volumetric qualities of light.” His World Trade Center 7 base, he pointed out, uses a subtle shift in plane to create an ethereal glow, while another project for Gucci in Tokyo uses prismatic light to recreate the qualities of a Japanese lantern. Other highlights included his louvered Israel Museum and his new exploration of optical aluminum, thin glasses, and computer etched glass.
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.

Net zero energy, LEED Platinum project raises the bar on eco-friendly office design.
For its new headquarters in Los Altos, California, the David and Lucile Packard Foundation put its building budget where its mouth is. The philanthropic organization, whose four program areas include conservation and science, asked San Francisco-based EHDD to design a net zero energy, LEED Platinum building that would serve as a model of cutting-edge green building techniques. “They wanted to achieve net zero in a way that was replicable, and that showed the path forward for others to follow,” said project manager Brad Jacobson. “It was not just a one-off thing, not just a showcase.” The building’s facade was fundamental to its success as an example of sustainable design. “We were surprised at how significant the envelope is, even in the most benign climate,” said Jacobson. “Pushing the envelope to really high performance made significant energy and comfort impacts, and could be justified even on a first-cost basis.” Read More
The newly opened Bullitt Center in Seattle has stridden beyond the checklists of the LEED rating system to bring “real green” architecture into the public’s eye. As the self-proclaimed “greenest commercial building in the world,” the Bullitt Center seeks to meet the exacting goals of the Living Building Challenge, a more rigorous certification alternative to LEED. Located in Seattle’s Capital Hill district, which is in the process of a metamorphosis into the city’s “Eco-District,” the six-story building aims to serve as a new standard for what can be accomplished when architects and developers put ecological design at the forefront of their priorities.

A motorized green wall that reads the weather and adjusts automatically
Two years ago six students and three faculty from Virginia Tech’s School of Architecture + Design spent three weeks at SOM‘s Chicago office applying industrial fabrication solutions to the problem of high density housing for Southworks, a housing development that’s currently being planned for a large vacant section south of the city. The result was LumenHAUS, an aggressively energy efficient home that won the international Solar Decathlon Competition that June for sustainable solutions to high density construction. LumenHAUS is not only net zero, it actually creates more energy than it uses by implementing, among other innovations, a modular system that autonomously responds to external weather information and internal environmental conditions to optimize energy use. This Fall Virginia Tech’s Center for Design Research will begin construction on a full scale prototype of six housing modules, including a working prototype of Hanging Garden, a dynamic plant wall that reads the weather and responds by sliding along the walls and windows to either block or allow sunlight into the living unit.
The new Electrical and Computer Engineering (ECE) building at the University of Illinois at Urbana-Champaign uses the latest in sustainable technology and building practices in hopes of reaching not only LEED Platinum, but even zero net energy usuage. Designed by SmithGroup, the 230,000 square foot building is also meant to serve as a prototype for sustainable building across the campus. The ECE department is working toward a net zero building that will supply one hundred percent of its energy demands by incorporating renewable energy systems. The architects and engineers from KJWW have integrated a range of system, including an array of photovoltaic cells panels, displacement and demand control ventilation, heat recovery chillers with net metering, and a chilled beam system for cooling and heating the classroom tower. The building also features solar shading and a multi-hued terra cotta rainscreen over an R30 building envelope. Construction is expected to begin at the end of this year, with an estimated completion date of fall 2014.
