Reading List: Subnature

Another book that engaged me on my hiatus from blogging is one I picked up on somewhat of a whim as it looked like a fascinating read. I wasn't disappointed, as 'Subnature: Architecture's Other Environments" by David Gissen, quickly became impossible to put down. The reason? It really tackles some interesting terrain that is definitely at the fringes of architecture and landscape, which typically addresses the realms purity and order, whether in terms of materials or the messy nature in cities.



To quickly summarize the main components of subnatures, these include: dankness, smoke, gas, exhaust, dust, puddles, mud, debris, weeds, insects, pigeons, and crowds.

The idea of subnature comes from a hierarchy between the supernatural (above nature) and the natural (our current world view), to include this subset of nature in which existence seems difficult if not impossible. Definitely not the standard fare of typical books on architecture, particularly in our current fascination with new space-age materials and technologies to solve problems, while only a minor
ity instead looking at context, natural materiality and process. Gissen's main thesis is we can capture the essence of these subnatures, we may, "...arrive at a truly radical and alternative concept of what environment means."

This is specifically engaging, as the evolution of the book, as explained by Gissen in the introduction, is that this information collected here was the residual ephemera from a more focused study an architecture and nature, including a range of historical and contemporary source material from a wide range of sources. While the main academic pursuit of 'natural architecture' is perfe
ctly relevant, (his dissertation included an 'exploration of nature in modern NYC buildings in the 70s) - the leftovers make for a much more interested concept.

So why is the subnature so interesting, specifically in the context of architecture and urbanism? Gissen mentions some of this context: "I draw on architectural and urban design theorists' key texts and contemporary practicioners' recent design to examine how both grou
ps envision peripheral and often denigrated forms of nature..." In essence, it's not just a historical look at unconsidered materials, but a way of looking at the natural processes in a new way. This is perhaps more authentic than many of the explorations and misuse of the word 'ecologies' (or landscape for that matter) in modern parlance, which takes a much broader (and cleaner) cultural view of interactions between organisms and environments.

There is some precedence for this realm of inquiry, including a few mentioned in the book. These include Antoine Picon's ideas of anxious landscapes, Gilles Clement's writing on the third landscape, and Francois Roche's (from R&Sie(n))
term corrupted biotopes - all of which explore postindustrial landscapes, debris, polluted ecologies, damaged nature. This coincides with some of our recent fascination with the dirty - including a focus on brownfields, post-industrial landscapes, vacant lands, air/water pollution, and other non traditional sites.

This is also why it is interesting to landscape architecture, as it is a clear refutation of the hermetic condition of pure architecture (i.e. a finished product offering refuge from 'outside'), and the desire to apply this condition to that of landscape, which is constantly in flux and infused with these subnatures. Is our desire to fight against these subnatural forces to create order in the garden, or is a more nuanced ecological approach to understand not just the base forces (geological, hydrological, meteorological) and understand the influence and opportunity of the subnatural forces at work.

Gissen frames this in practical terms as a means to achieving true 'sustainability'. The book "...offers an alternative vision to those contemporary municipalities, developers, and architects who seek to remake cities and buildings through the parameters of a more natural framework based on sustainable principles. Subnature also offers an alternative to the emerging vitalist discourse on 'flow' as the dominant effect of nature in architecture." Juxtaposed between the functionalism of the green building movement which "... advance a seemingly neo-Victorian and neo-Haussmannite vision of urbanism in many global cities... [which] often entails the utilization of nature as an instrument that cleans the world, increased productivity and efficiency, and transforms our existing natural relationship, while advancing the social sphere that exists." (p.23)

While not a specific critique of the green movement, it's more a re-engagement in some of the messiness that ensues from our working in nature and specifically subnature either directly or metaphorically. As mentioned, "Subnatures will not save us from our inequities, but its inherently alienating character enables us to consider how more comforting forms and dynamic images of nature are often used to reproduce existing forms of power in society." This is reflected in equity disparities of the rich being able to afford 'green' and the poor still being marginalized and left to reside with the leftover subnatures.

The final distinction is also made between the concept of reconnecting with nature, included in books like Earth Architecture, and one of my favorites The Granite Garden, and pretty much the crux of many of the projects that venture in new forms of habitat creation (such as PHREE Urba
nism), Animal Architecture, or much of the Veg.itectural featured on a regular basis. The photoshopped vegetated visuals versus the messy reality is sometimes difficult to reconcile, perhaps due to the subnatural forces at work. Similarly, Gissen distances the concept from the new theories in architecture that embrace material weathering from Mostafavi & Leatherbarrow, showing that "...evironments appear as fixed and stable systems relative to a dramatically changing architecture object." Weathering and veg.itecture have similarities in expression to date, as it is difficult to choose one or the other - wild process here but not here.

The book itself is visually rich, and is very readable - making it a good book for a range of audiences. While potentially veering into either the overly historicist or the overly theoretical, Gissen toes the line with a certain grace that shows adequate historical background but also modern applicability. The historical is the common jumping off point and ranges within the confines of a coherent thought process (say versus the content schizophrenia of BLDG BLOG)... but is no less interesting.

For instance a 1568 image (in the chapter on dankness) by Philibert de l'Orme showing the idea of a 'builder emerging from a dark cave to become an architect', a metaphor from the transformation from the subnatural realm to the natural.

Additional interesting ideas include the necessity of tobacco smoke in the authenitic experience of Philip Johnson's Glass House, Peter and Alison Smithson's work with rubble at the Robin Hood Gardens, the British Beehive, and countless examples both verbal and visual. Many of these are architectural in nature, but many transcend to include urban spaces or particularly landscape context, making (or blurring) the connection between the three and their various influences due to subnatural forces is a key aspect - beyond just the exploration of the forces themselves.

From the epilogue: "...perhaps this hypothetical architect considers these strange forms of nature as a material endemic to architecture and cities, as opposed to an aberration that must be consolidated, removed or dismissed. He or she is not only engaged with the realities of the modern world but with the social processes that surround architecture, urbanism, and history. To rid cities of subnature negates aspects of urbanity while advancing a narrow concept of architecture's proper environment. By seeing only these things that are useful to a building's program, an architect dismisses key aspects of contemporary urban life."

For me the conceptual and contextual framework of the argument is the most interesting component of the book. It is necessary to include modern interpretations of the application or
engagement of these subnatures, but for the most part these seemed somewhat less relevant, taking away from the overall impact of the argument. Perhaps this had to do with an amount of technological intervention sometimes required to achieve a balance with subnatures, more of forcing versus working with these processes. The examples are interesting, and definitely worth exploring (and many of them have appeared on the blogs throughout the recent couple of years). A typical example, for instance, is found in the category of exhaust. The B_mu tower by R&Sie(n) incorporates the exhaust of Bangkok into the form of the project, adding an element to the skin of the building that is responsive to the immediate context.

Read and see a full overview here.

"Bangkok is a very dusty gray and luminous city.The pollution cloud, CO2 residue, filters and standardizes the light with only gray spectral frequencies.Over 50 different words could be used to describe the tones and the touching aspects of the absence of color: “luminous, vaporous, pheromonal, hideous, shaded, transpiring, cottony, rugged, dirty, hazy, suffocating, hairy…” The dust dresses the city and her biotope, even going so far as to modify the climate. Within this fog of specs and particles, Bangkok becomes the melting pot of hypertrophic human activity with convulsing with exchanges of energy, where visibility becomes its greatest charm. At the antipodes of the canons of modern urbanism and its panoply of instruments lies, the city of Bangkok, ectoplasmic, super fluid to quote Kipnis. "

"She is conceived in between aleatory rhizomes where the arborescent growth is at the same time a factor of her transformation and her operational mode.The project for the future museum B-mu feeds off of the climatic opposition between the urban environment’s protuberant energy and the indoor subdued and subject to the museum conditioning procedures (white cube). We are talking here of two distinct geometric structures: one is Euclidian, globalization incased, where cultural merchandises are circulated in an aseptic and deteritorialized universe, and the other typology, plunged in a intoxicating urban chaos."

This look at old/new in tandem is really interesting, and illustrated the books simple beauty. To focus on one or the other exclusively would have made for a focused but somewhat less vibrant read. The beauty is also that it is so topical and necessary within the framework of our modern discussions of green building: "When we talk of architecture engaging with the environment, very often we mean to say that architecture is harmonizing with, or open to, some aspect of an uncorrupted nature. An architecture that engages with the environment usually incorporates or mimics the mechanics of trees, sunlight, water, and wind; whether developing a country house or a skyscraper, the architect attempts to work the form, program, and system of the building into a mutually beneficial relationship with the environment... But as this book has demonstrated, the environment is much more than the nature we often image to be in some prehuman and pristine form; it is composed of subnatures produced by social, political, and architectural processes and concepts. Unlike the natural environment, we cannot possibly imagine a subnatural environment generated by, nor found within, a nonhuman world. Subnatures force us to confront the implicit nonsocial character of nature, as it is invoked in discussions of architecture and the environment." (p.211)

While virtually impossible to adequately cover all of the content of this book in a short post, I'm hoping to expand some of the notions of these subnatures, so look forward to some additional posting around these concepts, weaving in some of Gissen's information and project examples and some other writings.

Stay tuned, and definitely get a copy of this book for reading and re-browsing. Fascinating stuff.

Sustainable Sites - Update

From some sneak peeks of the latest update to the Sustainable Sites Initiative (more from L+U here), I was both excited about the next iteration and establishment of more rigorous set of criteria, and a bit curious how it was going to maintain some of the necessary distance, inclusivity and poetry that is lacking in many other site rating systems. I'm not sure how I feel about the new split between the guidelines and the 'case' for sustainable sites



The full text from the Sustainable Sites website:

"The Sustainable Sites Initiative: Guidelines and Performance Benchmarks 2009 is the product of more than four years of work by a diverse group of experts in soils, hydrology, vegetation, materials and human health and well-being. It is expanded and updated from the Guidelines and Performance Benchmarks –Draft 2008, which was released in November 2008. The Initiative developed criteria for sustainable land practices that will enable built landscapes to support natural ecological functions by protecting existing ecosystems and regenerating ecological capacity where it has been lost. This report focuses on measuring and rewarding a project that protects, restores and regenerates ecosystem services – benefits provided by natural ecosystems such as cleaning air and water, climate regulation and human health benefits.

The Guidelines and Performance Benchmarks 2009 includes a rating system for the credits which the pilot process will test for refinement before a formal release to the market place. The Rating System contains 15 prerequisites and 51 credits that cover all stages of the site development process from site selection to landscape maintenance. If you are interested in becoming a pilot project to test this Rating System, please apply here. Feedback from the pilot projects will be used to create a reference guide which will provide suggestions on how projects achieved the sustainability goals of specific credits.

The companion document titled The Case for Sustainable Landscapes provides a set of arguments—economic, environmental, and social—for the adoption of sustainable land practices, additional background on the science behind the performance criteria in the guidelines and performance benchmarks, the purpose and principles of the Sustainable Sites Initiative, and a sampling of some of the case studies the Initiative has followed."

It's great to see a site-specific system taking shape, and can't wait to see it begin to permeate the discussion of true sustainability and green building - and addition long-lacking in the current dialogue. For a bit of additional info, check out this short presentation 'Landscapes Give Back' which makes a case for the role of landscape in this discussion. More to come.


More to come after I have a chance to take a look at the updated documents. Additionally, the concept of What is a Sustainable Site will be a common theme in the next year, as the Oregon ASLA embarks on a number of events, discussions, workshops, and symposia around this idea.

Bilbao Jardín Garden

A wonderful addition to the International Urban Garden Competition “Bilbao Jardín 2009”, by Diana Balmori of New York-based Balmori Associates and a design that literally 'climbs the stairs' with a undulating vegetated strip and cor-ten walls splaying out in a wider planter at the lowest landing.


:: image via Bustler - Photo: Iwan Baan

Some of the designers explanatory text, via Bustler: "The garden climbs the stairs, running in undulating lines of different textures and colors. Envisioned as a dynamic urban space; it moves in time and with the seasons. Its lush planting cascades down as though the garden was flowing or melting, bleeding the colors into each other. In one gesture, it narrates a story of landscape taking over and expanding over the Public Space and Architecture, therefore transforming the way that the stairs and the space is perceived and read by the user. It is a garden of contrasts: the contrast between native and exotic
plants, between the red flowers and the green grass, between the green grass and the grey paving. In form, the garden engages the horizontal plaza with the rising vertical plane of the steps and the upright gesture of Eduardo Chillida’s sculpture. Like the famous Spanish Steps in Rome, the garden is not only designed for visitors to ascend and descend, but for them to linger, and just be."

It's an elegantly simple composition, and definitely takes advantage of the 'topography' of the stairway and foreshortening perspectives utilized to create a constantly changing perspective of vegetation in a somewhat grand, but otherwise barren staircase area left between the architectural objects.

Animal House

An interesting urban habitat from Inhabitat, "...Gitta Gschwendtner’s Animal Wall is for residents of all species in Cardiff Bay, UK. This 50-meter wall includes 1000 houses for birds and bats, and also acts as a textural and geometric sculptural divider between a residential development and a river front."

I'm not sure if bats, birds, and other urban fauna are fans of modern brutalism (compared to parasitic organicism or perhaps vegetated blobitecture), but I'm guessing an abode of woodcrete is probably not bad digs, considering the range of urban options that wildlife occupy to make due in the city. These come in 4 different unit floorplans (all studios, furnishings by owner) and at an affordable square foot cost. As visitors move in in the spring, it'll be interesting to see how successful this particular urban housing project will end up.

Plants + VOCs

A recent, somewhat hyperbolic title from Treehugger, "Bad Green: Some Indoor Plants Release Volatile Organic Compounds" provides a snippet from some recent research that mention, gasp, that plants, particularly indoor ones, release volatile organic compounds (VOCs). It's a strange conceptual notion indeed, as there has been much research and information on the ability of indoor plants to improve air quality - including removal of VOCs and reduction of sick-building syndrome. So should we chuck the plant on the desk, and more broadly stop any notion of incorporating plants into buildings in significant ways? Probably not.


:: Killer Peace Lily - image via Treehugger

Some explanation "But at least four popular varieties of house plants emit their own VOCs, according to the University of Georgia's Department of Horticulture. Scientists there studied plants in glass jars and found 23 VOCs in the Peace Lily, 16 in the Areca Palm, 13 in the Weeping Fig and 12 in the Snake Plant. Sources included pesticides used in production of the plants, micro-organisms living in the soil and the plastic pots the plants called home, researchers say. The emission rates were higher during the day than at night, and several of the VOCs detected are known to harm animals."

It's not necessarily big news that plants give off VOCs... as plants are organically based and release compounds that are volatile (i.e. they vaporize readily into the air) through the normal process of metabolism. In fact one of the more readily occurring VOCs in nature is methane, which is produced in large quantities in wetlands. While not necessarily toxic, it is a player in global warming, so we should probably indict this as well while we're at it.

The difference between naturally occurring VOCs and synthetics are . Also a review of the study results identified that the primary VOCs from indoor plants were terpenoids, which are a somewhat innocuous form that provides a number of uses - and are particularly descriptive in having strong aromas. For instance the smell of such items as cinnamon, cloves, ginger, and eucalyptus is caused by the terpenoids present in these plants. Without these our sensory world would be much more bleak.


:: terpenoids look scary in molecular form - image via Wikipedia

Conversely a number of VOCs we are commonly bombarded with indoors, particularly in new construction, are related to
paints, adhesives, solvents, cleaning agents, caulks, wood products, carpets and sealants, and their lovely sounding components of toluene, styrene, xylene and ethylbenzene. As it's easy to tell from a fresh walk down the halls of a new (even sometimes low-VOC green) building, as chemicals off-gas from these materials and invade our smell centers in negative ways, something foul is going on. And, as mentioned in the report, it is likely the major issues with VOCs and indoor plants come from off-gassing of worse compounds from the man-made plastic pots, and pesticides used in growing of the plants... as well as microorganisms in soils and growing media.

This is another compelling reason for a holistic transformation of the landscape and nursery industry to include the whole picture and not just assume that plants are good or bad. While this doesn't say that there isn't something to this idea of VOCs from plants (it's natural) - let's not jump to quick and overwrought conclusions about the perils of house plants without a bit of context and further exploration. I think the precautionary principal is fine, but to eliminate indoor vegetation without some more focused study on impacts is pretty poor form, particularly when many materials used in building and landscape construction are known to be bad, yet still are industry standard.

I'm willing to be that when the overall accounting is done, exterior plants and wetlands probably have a net benefit to our environment, and indoor plants will win out in the search for better indoor air quality. Just a hunch.
