A Filtered View #6: The Sustainable Building Artistically Considered
In our culture of fashion-driven design, a sustainable building will have to succeed aesthetically to be truly sustainable.

Editor’s note: This is the sixth in a series of musings by San Francisco-based architect Charles F. Bloszies, FAIA.
Someday we will run out of fossil fuel, and eventually buildings will need to power themselves. This is not a new concept; in fact, the very first buildings to rely on electricity to illuminate Edison’s light bulb generated their own power employing coal-fired dynamos in their basements. Today, technologies for building integrated power generation are improving at a rapid pace, new energy-producing materials are appearing on the market, and the cost of building components based on these technologies is going down.
Regrettably, early adopters of power generating technologies have not yielded an architectural vocabulary that is especially pleasing to the eye. Solar panels and wind turbines are often handled clumsily and look like science projects gone awry rather than components truly integrated into or driving the overall building design. Even worse, some don’t seem to work at all or yield insignificant amounts of power. Despite these early attempts, there is enormous potential for creation of buildings that are self-sustaining and beautiful, too.
Throughout the history of architecture, technical advances have led to new architectural paradigms. Take the arch, for example. A structural innovation made the Gothic cathedral possible, and when it didn’t quite work, it spawned an even more architecturally rich element – the flying buttress. Centuries later, the emergence of the steel frame along with the elevator ushered in another shift in the architectural paradigm. In part, these two technological breakthroughs provided a means to address a societal need – cities could grow vertically to accommodate more people as they moved from rural areas into urban environments. Architects of the time failed at first to find an aesthetic expression of these new innovations, which led Louis Sullivan to pen his famous 1896 essay, “The Tall Office Building Artistically Considered.” As a consequence, the modern skyscraper was born, following his famous edict “form ever follows function.”
We are in a similar time now. The societal need today is to find ways for buildings to be at least partially self-sustaining, and contemporary technological breakthroughs include many new power generating materials and systems. Architects have taken the forces of sun and wind into account in their designs for centuries, and continue to do some very good work using passive design approaches. In some cases these forces have shaped a part of a building or the entire form itself. The façade of Barkow Leibinger’s Tour Total in Berlin is both beautiful and functional as it blocks the sun. Studio Gang has used the sun’s rays to carve out a building form to minimize shadows of its Solar Carve Tower on New York’s High Line. These gestures are rare, but almost nonexistent are truly clever building forms like these that also generate power. Perhaps the influences of sun and wind are too fluid and too complex to lead to any particular architectural idiom?
Work in the studios of nearly all architecture schools is also puzzling. Most students have taken sustainability very seriously, and have applied analytic tools to evaluate site and climate conditions. However, they seem to be using their most powerful tool, parametric modeling, only as a generator of complex, gravity-defying geometry rather than as a means to drive designs expressing the results of their analyses.
Exemplary built work is also hard to find. At one extreme is London’s Strata Tower by BFLS Architects (now Flanagan Lawrence), a 43-story building with three giant wind turbines forming its slanted top – it won Building Design magazine’s 2010 Carbuncle Cup as Britain’s ugliest building. The turbines, purported to generate 8% of the building’s power needs, never really worked, and when they did, they made so much noise the penthouse occupants asked them to be turned off. Six years later, the turbines remain silent. At the other extreme is a little gem in Melbourne – the Pixel Building, designed by studio505, exuberantly expressive of its sustainable attributes, including on-site power generation and rainwater harvesting in sufficient quantity to satisfy 100% of its power and water needs. Its designers claim to have qualified for 105 LEED points – the highest rating for any building in the world.
Success is often preceded by failure, but unfortunately in architecture, aesthetic failure endures for a long time. Nonetheless, architectural pioneers in this arena should be applauded because they have shown how difficult it is to use power generating components as design drivers. But the need for self-sustaining buildings, or at least buildings that consume far less of the grid’s electricity, is growing more urgent as every year passes. In our culture of fashion-driven design, a sustainable building will have to succeed aesthetically to be truly sustainable. Outdated as they sound today, Sullivan’s words still ring true.
Charles F. Bloszies, FAIA, is an architect, structural engineer, and writer – and principal of a practice in San Francisco focused on complex urban infill projects. He is the author of Old Buildings, New Designs – Architectural Transformations, published in 2011 by Princeton Architectural Press and now in its third printing.
Maybe Apple should design all of this stuff; or maybe Philippe Starck.

It may take a decade or so before photovoltaics and other energy-producing technologies find an aesthetic foothold, but for architecture to survive - they must.

红桃棋牌官网Melbourne’s Pixel Building by studio505 could be deemed an exuberant expression of sustainability. It generates all of its power as well as captures and stores 100% of the water it uses. The colorful pixels are shading devices for planters containing water filtering plants. It claims to have qualified for 105 LEED points – the highest rating for any building in the world.
The Construction Index
London’s Strata Tower by BFLS Architects (now Flanagan Lawrence) claimed it had “truly embraced sustainable design," but its notoriety stems from winning Britain’s Building Design magazine’s 2010 Carbuncle Cup as the year’s ugliest building, in part because it resembles a giant shaver.
