The Red Brick Chronicles - 'Advancement verus Apocalypse' by Rem Koolhaas

As I mentioned in the recent reckoning of the L+U blog, I wanted to focus on a number of recent texts that I've had the chance to delve into (by disconnecting myself from the nefarious teat of the RSS feeder)  Of significance is finally getting around to expanding on the initial readings of the book Ecological Urbanism (check out Intro by Mohsen Mostafavi, 'Why Ecological Urbanism?  Why Now?, in two parts here and here) which although gigantic, dense and brick-like, is also yielding some engaging content.


Thus in lieu of another option for a book with over 100+ essays and snippets from various authors, I'm going to chronologically post on each one on a mostly, time permitting, daily basis - in some cases just a fragment or two worthy of discussion - sometimes in more length.  Hope you enjoy.  Here's the first installment - follow by regular installments with the moniker RBC.

________________________________________________________

Advancement versus Apocalypse
|  Rem Koolhaas

In this essay, which I gather is a short-form version of a presentation, Koolhaas provides a hybrid chronology of modern progress, focusing on  “…the coexistence of modernity and endlessly improvised, spontaneous conditions that don’t consume much energy or material. For me, a hybrid condition is the condition of the day.” (56)   Through searching history in the framework of ecological urbanism, he finds some precedents in the early indigenous knowledge of people, noting that over 2000 years ago, the basic tents of ecology were known, expressed in the vernacular, utilitarian architecture where people would “…build to be economical, logical, and beautiful.” (57)  This concept and focus on the site and siting of cities was echoed in the Ten Books of Vitruvius, through the Renaissance, and to the Enlightenment, which."...had a phenomenal effect on reason, in terms of triggering the apparatus of modernity in a surprisingly short time.” (58)

Thus along with the science and technology of modernity can the apocalyptic baggage best expressed by Malthus in the late 18th Century, and continued in more modern times through authors like Paul Ehrlich in the 1970s (Population Bomb) and even into today's discussions of peak oil and environmental degredation, referenced by James Lovelock (The Revenge of Gaia).

Koolhaas mentions an earlier formative experience with the ecological in the late 1960s, mentioning instructors working with tropical architecture that instilled a “respect for the landscape” and the ability to “look at other cities to see how they work , and to look at seemingly nonarchitectural environments.” (60) and expressed in attempts at the time to combine design and science such as Ian McHarg's 'Design with Nature' referred to as “...one of the most subtle manifestos on how culture and nature could coexist.” (62)

Koolhaas expands this with a quote from Frederick Steiner in‘The Ghost of Ian McHarg: 
“Almost 40 years ago, Ian McHarg proposed a bold theory and a set of ecologically related planning methods in Design with Nature (1969). While the proatical measures he proposed have been incorporated into subsequent design and planning practices, the theoretical implications have not yet been fully realized. Present-date forms of the model include the amalgam ‘landscape urbanism,’ with its focus on infrastructure an\d urban ecology, a hybrid discipline arguably indebted to McHarg while distinct in its avoidance of the more strenuous effects of his project.” (62)
In addition to McHarg the text mentions contemporary Buckminster Fuller's focus on the "...combination of nature and network...” expressed in this network diagram of global high voltage transmission networks (62) and also the work of the Club of Rome – Limits to Growth in 1972 (strangely enough a notable reason in Jonathan Franzen's recent book 'Freedom').

The environmental intelligence of the 1970s was soon quashed by the market economy, as Koolhaas mentions, “...had a devastating effect on the knowledge that had accumulated at this point.” (65)  The current situation of economics gain over ecological approaches has continued since the 1970s.

Shifting gears a bit, the current focus on ecological urbanism is the role of technology, specifically indicative of the engineering/technology will save us paradigm epitomized by Freeman Dyson – quoted in the NY Times: “...proposed that whatever inflammations that climate was experiencing might be a good thing because carbon dioxide helps plants of all kinds to grow. Then he added the caveat that if CO2 levels soared too high, they could be soothed by the mass cultivation of specially bred ‘carbon-eating trees’…” (66)


In addition to noting these radical technological fixes, Koolhaas also bemoans the current trend of boutique green-was expressed in the application of greenery to buildings, mentioning that, "Embarrassingly, we have been equating responsibility with literal greening." (69), mentioning specifically the Ann Demeulemeester store in Seoul, the work of Ken Yeang and the recent Renzo Piano design for the California Academy of Sciences building as examples of this travesty of architecture.

 :: Ann Demeulemeester Store in Seoul - image via Style Frizz

 This confuses me, as while I am not as excited about the green application of vegetation, the inclusion of the specifically bioclimatic architecture of Yeang seems misplaced, as it seems an expression of ecological urbanism.  Instead, Koolhaas finds merit in building new eco-cities in the desert, mentioning Norman Foster’s Masdar zero-carbon city as "serious", and a step forward from the boutique natural interventions of Yeang and Piano, mentioning:  “...we need to step out of this amalgamation of good intentions and branding in a political direction and a direction of engineering.” (70)


:: Masdar City - image via Menainfra

While a somewhat interesting exploration, it is somewhat circuitous and peppered with Koolhaas' self-professed doubt in the overall project, mentioning in the intro "I did not assume that anyone in the academic world would ask a practicing architect in the twenty-first century, given the architecture that we collectively produce, to participate in a volume on ecological urbanism..." (56)  This perhaps colors the text somewhat away from individual buildings and more towards the massive, techno-centric solutions from Koolhaas/OMA - such as the large-scale wind energy project in the North Sea mentioned in the end of the essay.

It's obvious therein lies a distancing from the individual ecological building in the context of these bigger, more significant infrastructural interventions - which marks a distinction, notably with the architecture of Koolhaas being rigorously programmatic, urban-engaged, but typically non-ecological.  Maybe the realization that one building here or there isn't going to be the solution is valid and worthy of discussion?  Is ecological urbanism about large-scale ecocities or infrastructure, or the aggregation of interventions at a variety of scales - maybe even including buildings?

(from Ecological Urbanism, Mostafavi & Doherty, eds. 2010, p.56-71)

Landscape Performance Series

Interesting link to the Landscape Architecture Foundation's new resource - the Landscape Performance Series - which is sort of an adjust to the Sustainable Sites Initiative which is "...designed to fill a critical gap in the marketplace and make the concept of “Landscape Performance” and its contribution to sustainability as well known as “Building Performance” is today. The LPS is not a rating system, but rather a hub that brings together information and innovations from research, professional practice and student work in the form of case study briefs, benefits toolkit, factoid library, and scholarly works.


As someone who is adamant that our profession attain a much higher level of rigor in determining the efficacy of designs, this is a great new addition.  The projects are interesting, cover a wide range of landscape typologies, and offer data that is not available in typical media 'puff-pieces' or even more technical papers.  A typical case study includes a number of interesting features.  For instance, a look at the great Seattle project, the Thornton Creek Water Quality Channel, provides an overview, sustainable features, challenges/solutions, cost comparisons, lessons learned, and project team.

:: image via LAF

While the data is more expansive, we still have a long way to get really good information that can not just validate projects but can also drive future design solutions.  Information on cost, performance, and technical data is still anecdotal - not saying it doesn't exist, but that it either hasn't been studied, or hasn't been released.  The issue with data and research is always not the results, but the methodology and transferability to future projects.  Every landscape architect should study the Case Study Method for an approach to post-occupancy evaluation, particularly Mark Francis' article in Landscape Journal, that should become the foundation of every project - not just those with innovative features or with funding to provide necessary data.  

:: image via LAF

From a design perspective, we need greater access to available research.  I've had an interesting (and wonderful) opportunity to have access to the research library resources of a major university, and it has been amazing to see all of the data out there that has not trickled down to the design community in a meaningful way - even when you are actively searching for this information.  Take for instance the state of research in Green Roof technology, which in common access is limited to minimal, local, or specialized data on soils, plants, and benefits.  

:: image via Greenroofs.com

A very quick survey of some recent literature yielded international data on building heat flux, growing media for stormwater retention, water quality and building insulation, energy performance, plant establishment, habitat function, cost/benefit through life-cycle assessment, economic value, innovative structural techniques and systems, and heat island mitigation.  In addition, there are technical studies that offer innovative modelling techniques that provide macro-scale, not just site specific data, about the benefits of sustainable strategies, including green roofing.

:: image via Inhabitat

Aside from anecdotal, feel good stories about ephemeral or vague benefits, these offer tangible examples of research that can lead to better design and implementation.  While all of these research studies are not immediately transferable, many are, and it highlights the need for designers, even those not doing research, to be more involved in the creation of research agendas that will actually lead to better solutions.  It's not an either/or scenario - but one where we much work together if we are to make our landscapes more viable, but also give ourselves the tools to measure and evaluate them.  I commend the LAF for their work - and encourage others in the landscape architecture community to support and expand this work.

Ephemeral Urban Gardens: Temporality + Mobility

The last remnants of ephemera sitting around the archives is under the auspices of terrestrially based gardens within the foodsheds of our cities, and - and the need to address the issues of permanence (both the pros and cons). One option is to incorporate food production within our permanent landscaping by using the principles of permaculture to imbue these spaces with productive elements. While gardens in our cities that are permanent fixtures are a necessary element to complement density, parkland, and natural open spaces, there are hundreds of acres of available land and other spaces that can be utilized for growing food - to both take advantage of the temporary availability, and make urban agriculture visible to city dwellers.


:: image via Inhabitat

The use of brownfields brings up many issues (read about Portland's issues here) - but are for the most part compatible with . Check out this EPA report on brownfields and urban agriculture for some data on the subject. In addition, many recent proposals aim to and have the ability to provide temporary occupation of sites - requiring the mobility necessary to move sites on a yearly or short term basis without issues of displacement - maximizing the return on investment by being nimble - a very anti-slow food ideaology - but a necessary one to benefit our cities in productive ways.


:: Garden to Go - image via Designboom

The visible aspect of gardens can take on elements of public art, such as the Sharecropper Micro Farm project - and art installations in NYC cultivating heirloom vegetables at multiple, simple locations through the City.


:: image via Inhabitat

Small modular ideas abound such as the 10x10 project from MIT and Columbia University 'Urban Design Labs', a modest proposal via City Farmer "To help production, the group advocates widespread adoption of small-scale innovations such as “lawn to farm” conversions in urban and suburban areas, and the “10 x 10 project,” an effort to develop vegetable plots in schools and community centers. Lawns require more equipment, labor and fuel than industrial farming nationwide, yet produce no goods. But many vegetables, including lettuce, cucumbers and peppers, can be grown efficiently in small plots."



:: image via City Farmer

This simple planter based idea from Tokyo Green Space highlights the ability to grow food in simple containers and small spaces - in this case neighborhood rice - which are easy to multiple to scale production.


:: image via Tokyo Green Space

Small scale interventions also can include such expanded ideas as aquaponics, such as these personal solutions from Aquaponics USA. Beyond small (which is preferential for mobility), actual transportation and movement of planters is often problematic, as the building of soil along with community is an aspect of gardens we seem conflicted about - and often reduces our ability to occupy any spaces. We need to re-frame the temporal notions of occupation of spaces - and also what's allowed in cities.


:: image via Inhabitat

A couple of recent ideas come from both two North American cities. First, from San Diego, is The Farm Proper, a "...mobile, urban farm under development in the lot behind THE BAKERY, the Set & Drift and mi-workshop collaborative studio space in Barrio Logan. The Farm Proper is an experimental project created by a collaborative of artists, designers, and backyard growers to inspire urban cultivation and pocket farms. Using abandoned/defunct shopping carts as our medium, we have designed a scenario to take over a temporarily available industrial lot to provide the community with organically grown food."


:: image via City Farmer

Another is called the 'Mobile Food Collective' which is a student project from Archeworks:
"The students envision the Mobile Unit as the place where communities will come together and participate in their food heritage. At the Mobile Unit people can gather for discussions, to archive recipes, exchange seeds, share meals and participate in demonstrations on planting, growing and cooking their own food. A fleet of bikes with custom trailers accompanies the Mobile Unit. The bikes carry farming and gardening tools and transport the "mods," the nesting storage bins below the table, which house programming material. The accompanying bikes can also be used to deliver CSA boxes and are dispersed throughout a community to alert and direct residents to programming happening at the Mobile Unit."


:: image via Mr. Brown Thumb

This FEMA trailer offers a mobile brand (via Treehugger) - similar to the food cart/mobile restaurant phemomenon - also included with the Truck Farm in Brooklyn, and this mobile greenhouse. Another is "The Armadillo, a FEMA trailer that was transformed into a mobile, vertical community garden by MIT students and faculty."



:: image via Treehugger

Bagsacs are one example - shown recently on Designboom - offering mobility and temporary placement:


:: image via Designboom

A few variants include more temporary bags - such as these in Kenya to combat hunger issues and lack of farmland.


:: image via City Farmer

Or suitcase 'gardens' with built in portability, via Moco Loco.


:: image via Moco Loco

The temporality is an issue worth exploring, and the ideas of ephemeral spaces such as Pop-Up Parks or other Pavement to Parks initiatives and give some precedence that can be applied to urban agriculture: An example from the NY Times for an irregular-shaped parcel on loan for a finite time and used for an art-space. "Appropriately — given that the lot is on loan for about three years from developers who had hoped to build there by now — the project will be called LentSpace." There is not reason this couldn't be a model for agriculture instead of just ornamental plantings.


:: image via NY Times

From a farming perspective, this offers opportunities even without the investment of raised planters, such as Hayes Valley Farm in San Francisco, which is a vacant parcel that will be occupied for 2-5 years depending on the eventual development path of the site (i.e. a building).


:: image via Inhabitat

Mobility also includes mapping - which offers great promise for access to food - such as online resources for gleaning - such as the 'Find Fruit' app for I-phone.


:: image via People and Place

Finally, perhaps it bleeds into concepts of maintenance, as large swaths of rooftop greening could support herds of urban sheep that can be moved around periodically, and also be used for sustainable production of wool and eventually meat. The possibilities, as they say, may be endless.

Rooftop Agriculture

I've purposely steered away from the pure rooftop farms in discussions of vertical farming solutions recently featured (here, here, here, and here). This isn't due to any particular reason other than I think that rooftop farms area a separate typology in it's own right - as it is focusing on a separate area of emphasis including horizontality and openness to sun and air. For instance I mentioned the greenhouses at Zabar's - but there is also a significant amount of traditional rooftop agriculture.


:: image via City Farmer

Otherwise, plenty of proposals abound for rooftop planters on housing, and event making it's way into corporate campuses for use by workers. One example is the simple Sophos Vancouver Rooftop Community Garden - implemented on an office rooftop.


:: image via City Farmer

Recent proposals (and there have been many along with a lot of press) incented me to look through a number of these rooftop examples past and present as a way of rounding out the vertical farming survey.
First, via The Architect's Newspaper: "The Fifth Street Farm Project has it all: It addresses childhood obesity, stormwater runoff, and climate change. Conceived by a grassroots organization of teachers, parents, and green-roof advocates, the project’s plan calls for a roof farm atop the Robert Simon Complex..."


:: image via The Architect's Newspaper

A troubling quote I think brings up some inherent issues as we drive towards implementation of rooftop farms - and some of the challenges that are necessary to address. As quoted in the article: "In spite of all the good intentions, there are formidable technical hurdles and political challenges to building a farm on top of a school. “There’s a lot of bureaucratic craziness,” said Susannah Vickers, director of Budget and Grants in the office of Manhattan Borough President Scott Stringer, "...Things as arcane as the warranty of the roof—they have to do boring samples and engineering reports—and oftentimes the roof substructure is not able to support the new use.”



:: image via The Architect's Newspaper

These aren't arcane or minimal issues - but fundamental to proper technical installation that meets project goals while protecting the health, safety and welfare of the community - and specifically the kids at these schools. A recent example of a project gone awry in Vancouver, and a related story of the Brooklyn Grange installation in Queens getting a stop-work order for not filing necessary permits reinforces the need for these project to both have the energy of urban farmers, but also the technical backup and processes necessary to ensure they are appropriate. (The stop-work order has subsequently been lifted after permits were filed and a fine paid, which is good news as this project is gonna be pretty awesome).



:: image via Brooklyn Grange Farm

The Brooklyn Grange Farm was preceded by the amazing Greenpoint, Brooklyn rooftop farm 'Eagle Street Rooftop Farm' - which features 6000 s.f. of rooftop growing and 200,000 pounds of soil - not in containers, but as monolithic soil based growing - lessening initial investment and maximizing productivity.


:: image via NY Magazine

A local precursor on the west coast isn't the Rocket in Portland - but rather the Fairmont Hotel in Vancouver, B.C. which has been in operation since around 2000 - making it one of the very first examples - and also one with some good economic data: "Hotel accountants say the roof garden produces fruits, vegetables, herbs, and honey worth about $16,000 annually."



:: image via City Farmer


:: image via City Farmer

Japan has been looking at rooftops, as limitations in the amount of arable land . City Farmer shows a photo of one example: "Wasted space in the modern metropolis may become productive “farmland” thanks to advances in waterproofing green roofs. Some of the rice used to brew Japan’s popular Hakutsuru sake grows atop the company’s Tokyo office."



:: image via City Farmer

The first issue of Bracket with the topic 'On Farming' offered some One of these is Long Island City: Farming Park.
A bit of project description:

"All too often we see land being taken away for parking and at the same time the reclamation of abandoned parking lots to turn into viable land, specifically farms in urban environments. The project, which is a park and ride facility and urban agricultural farm attempts to combine these two typologies to co-exist on one site, bringing the process of food production and consumption in contact with a major multi-modal transfer point between the car and NYC’s existing public transportation network. The project will provide an alternative option for those accessing NYC by car and also challenge the conventional function of a park and ride facility to provide a greater good for those users and the surrounding neighborhoods; connecting Long Island City and Sunnyside Queens with a much needed public green space. "

:: image via Bustler

As [BRKT] showcases, there are plenty of zoomy architectural options out there - some of these simple and brilliant, others a bit overwrought with possible maintenance and installation issues. One very cool example (that may lean towards the overwrought side of the perspective) - comes via Pruned is Taebeom Kim's Gastronomic Garden - including: "...allotment gardens hovering over — perhaps are even propped up by — compost tanks used for recycling garden scraps as well organic waste of local residents."

Vertical Agriculture (Back to Earth)

Digging through the archives based on the last couple of posts, I was definitely struck by the myriad shapes and sizes that these vertical farming proposals take and the overall excitement that has grown in a short amount of time. This caused me to want to dissect them a bit further in terms of form and function for growing food in efficient ways. First a bit of background from the 'invention' of vertical farming on this video featuring Dr. Dickson Despommier.



Discounting for a second those proposals that incorporate indoor hydroponics using artificial light - the idea of growing in buildings using sunlight is the focus (some info about the indoor varieties) of many other projects out there. A few additional proposals worth noting - just to include them in the overall catalogue (as previously mentioned, the best assortment of ideas in this genre is found at the Vertical Farms site - under the auspices of Despommier - which has been interviewed multiple times (here, here, here, here, here, here, and here to name but a few) - call him the mother of this particular invention.

These proposals include this one from last year which got a lot of attention, Harvest Green by Romses Architects, featuring vertically integrated food production.


:: image via Treehugger

Via Treehugger: "The concept of 'harvest' is explored in the project through the vertical farming of vegetables, herbs, fruits, fish, egg laying chickens, and a boutique goat and sheep dairy facility. In addition, renewable energy will be harvested via green building design elements harnessing geothermal, wind and solar power. The buildings have photovoltaic glazing and incorporate small and large-scale wind turbines to turn the structure into solar and wind-farm infrastructure. In addition, vertical farming potentially adds energy back to the grid via methane generation from composting non-edible parts of plants and animals. Furthermore, a large rainwater cistern terminates the top of the 'harvest tower' providing on-site irrigation for the numerous indoor and outdoor crops and roof gardens."




:: images via Treehugger


Another smaller scale example from Romses Architecture features the idea integrated into a eco-community. From Arch Daily: "“Harvest Green Project-02′ as a part of Vancouver ‘The 2030 Challenge’. Harvest Green Project is rooted in a concept that challenges the status quo of how energy and food
is produced, delivered and sustained in our city, neighbourhoods, and individual single-family homes. Taking cues from the citys eco-density charter, and in particular, it’s new laneway housing initiatives, the Harvest Green Project proposes to overlay a new ‘green energy and food web’ across the numerous residential neighborhoods and laneways within the city as these communities address future increased densification. The city’s laneways will be transformed into green energy and food conduits, or ‘green streets’, where energy and food is ‘harvested’ via proposed micro laneway live-work homes."

Some others you've probably seen over the years:

Vertical Farm by Mithun
"Architects at Mithun, a Seattle architectural firm, proposed a small-scale vertical farm design for a Center for Urban Agriculture in downtown Seattle. The design won an award in the Living Building Challenge of the Cascadia Region's chapter of the U.S. Green Building Council in 2007."

Atelier SOA Vertical Farm

Via NY Times: "A vertical farm has to be adapted for a specific place," said Augustin Rosenstiehl of Atelier SOA Architects in Paris, whose firm has created renderings of the crop-filled skyscrapers."

Gordon Graff's Skyfarm for Toronto

Via Inhabitat: "Instead of soil, Skyfarm’s plants float on trays of nutrient-rich water, growing hydroponically over 59 stories stacked half a dozen storeys deep. Farmed within a controlled env
ironment, crops will no longer be subject to the vagaries of climate, infestation, or disease and the dense hydroponic agriculture can guarantee considerable yields. With the potential to operate year round, one indoor acre has been estimated to be able to yield the equivalent of between four and six outdoor acres, or enough food for 50,000 people a year. With the installation of several Skyfarms in the neighborhoods of especially large cities, the prospect to dramatically transform local food production is there."

Urban Agriculture: Hybridized Farm Bridge as City Garden - Kenny Kinugasa-Tsui & Lorene Faure



:: image via Bustler

A more technical proposal, I covered this previously, but the breakdown of the elements of a vertical farm as imagined in NY Magazine - which shows the interrelated elements of a possible project - complete with robots to maintain them on a 24-hours a day basis.


:: image via NY Mag

I think the much more exciting news is the implementation of large-scale rooftop farms (more on this soon) - which seem to be analoguous to terrestrial farming.
As other bloggers may have noticed, any post related to urban agriculture and vertical farming will inevitably lead to a comment by Charlie - there's been a few, who undoubtedly is paid to plug Valcent whenever the opportunity arises. The message is simple and sweet: "“I can’t think of any technology that addresses more urgent issues than Valcent’s vertical farming system”, says Robert F Kennedy Jr. http://bit.ly/cPb00g; Reuters Video features Valcent’s VertiCrop vertical farming system: http://bit.ly/a9p47W" Not that I'm wholesale against this form of promotion, but 1) is shameless promotion, and 2) it's not applicable to the content that was posted. Regardless - there will be more of this as companies fight for market share and prominence in this fledgling territory.


:: image via Inside Urban Green

Finally, as I mentioned there's some interesting (and necessary) debate happening, which is worth a read as the pendulum of vertical farming swings back to reality. There's the debate on Treehugger"Vertical Farms, a Tower of B.S." about high-rise farming. Also of note is this recent article in Fast Company entitled which references a story on EcoGeek with some cautionary lessons entitled: "Let's Make This Clear: Vertical Farms Don't Make Sense ".

The vertical farming movement isn't useless by any stretch - but it's important to realize that these proposals - although provocative, aren't the only answer to our issues of feeding people in ever growing urban areas. The discussion is good, although interesting that - not as a mode of discounting the concept - but of placing it in it's proper context around the viability of growing food in cities - and by most importantly making it a catalytic movement in inspiring actual small-scale solutions that will actually work.
