Nice video from NPR on Why Cities Need More Green Roofs. From the summary. “We took a field trip to the largest green roof in New York City. Then we imagined what the city could be like if all of its roof space was green.”
Regular readers of the blog know of my long-time passions of both Vegitecture and Hidden Hydrology, which both dovetail nicely into the larger themes of Landscape+Urbanism. While the L+U blog has been relatively intermittent, I’ve been hard at work developing a new website and blog for the Hidden Hydrology project. The goal is to culminate the work in some form of publication, but regardless, it seemed time to focus on that element in it’s own. I’m also giving a talk at the Washington ASLA conference in Spokane later this month (April 21), so excited to share more to a broader audience. Simply put, the project is summarized as:
“Exploring lost rivers, buried creeks & disappeared streams. Connecting historic ecology + the modern metropolis.”
Without going into too much detail that may be gained by going to the site itself, the project is broken down into four sections. The first section gives a quick overview of hidden hydrology and links to some of my original inspirations, including Anne Whiston Spirn and David James Duncan, along with an early, evocative map of Portland, along with the amazing historical ecology around the book Mannahatta.
A bit longer summary gives some context for the endeavor: “At the basic level, hidden hydrology is the buried, piped and disappeared waterways that flow under our urban areas. Development has driven underground these surface streams that used to weave through our cities – and with them we’ve lost the connection to natural systems, and robust ecological habitat that urban waterways can provide. Beyond just focusing on pure daylighting and restoration, the exploration, mapping, and study of hidden hydrology offers new ways to conceptualize a range of interventions that reconnect us to our history and offer glimpses of solutions for the future. It’s a broader concept of ‘restoration’ that looks through lenses of art, landscape architecture, urban ecology, and planning to define ways to celebrate, connect and regenerate our places.”
The second section are links to many of the resources available, including precedents, projects, and resources from around the globe. While linking to the other pages, I’m also providing links to some of the posts, including a diverse mix from Rome to London, San Francisco to Lexington, Kentucky. The range of projects isn’t limited to projects, but encompasses art, mapping, poetry, literature, dance, stream daylighting, films, community engagement, and history.
A couple of highlights, including the project “Ghost Arroyos” in San Francisco:
Or the cool mapping work of David Ramos in DC at Imaginary Terrain.
The third is an ongoing exploration of themes in a more expanded format, the site is built aroud a blog that has delved into some of the resources, and projects, but also allows for some rumination and coverage of original project work. Of the 25 or so posts to date, many have covered cities and projects, expanding to case studies and deeper investigations. These include projects inspired by hidden hydrology (such as Town Branch Commons in Lexington, top below), as well as historical maps and photos referenced in a literary context (Iain Sinclair’s ‘Swimming to Heaven’), and more in depth historical ecological studies (San Francisco Estuary Institute) to show a few.
The diversity is what surprised me, to different tendrils which weave beyond just mapping but into a multitude of subjects. An early post on the site, is illustrative of this concept, and is still one of my favorites, focused on the novel by Ben H. Winters, Underground Airlines and it’s use of the hidden hydrology of Indianapolis to tell a futuristic narrative of modern day slavery.
An excerpt from the novel explains this in a bit more detail.
“I cleared the trailer park and passed a jumble of picnic benches and playground equipment and stepped carefully down the slope of the ravine and swung the heavy beam of my flashlight along the creek. Now it was clear, with the water swollen by the rains, the direction the brown water was still flowing. The black mouth in the base of the shallow hill was an entrance, not an exit. This low little trickle of mud water was a kind of rivulet, a poor cousin of a creek, and this spot behind the motor court is where some long-ago engineer had diverted it.
The creek was called Pogue’s Run. I’d found it on the map. I’d looked up the story. This small waterway was discovered at the turn of the century – the eighteenth turning into the nineteenth — discovered and named and recorded, penciled in on early maps, when the city was not yet a city — when it was a gathering of huts, a stopping place on the way to other places. The small river was inconvenient for the city fathers and the grid they’d drawn. So they did just as Mama Walker said: they ran it underground.”
Beyond the fringes of hidden hydrology include some diversion into the very cool Atlas of Oblique Maps, a fascinating set of historical climate maps from the 1850s, and the ever popular Fisk maps of the evolution of changes to the Mississippi River.
The fourth, which is more of a long-term is projects, is still in nascent stage, but offers the potential to showcase original work around Hidden Hydrology, specifically in Portland and Seattle, but encompassing some other miscellany as well. Currently it highlights some early presentations, as well as base-mapping of the Cadastral Survey for each city, the springboard for further analysis.
The Mississippi maps inspired me to use some of the documentations to animate the changing course of the river within the valley over the last 4000 years. These more
There’s a ton of great information out there, yet it’s an area of study that seems relatively untapped and full of potential. If you’d like to contribute, know of some great case studies, and have the bug for historical maps, and how these can inform ecological design today, give a shout. In the interim, check out the site and follow @hiddenhydrology on Twitter.
And stay tuned for some more explorations here at L+U related to urban ecology and habitat, and more posts on some recent vegitecture, as I am working on some related projects and doing some more focused research in these realms.
It’s been unseasonably cold this winter (in Pacific Northwest terms at least), and while my friends to the south in Portland dig out of their recent snowstorm, locally, there are some benefits, such as the amazing phenomenon of ice circles. Captured by local photographer Kaylyn Messer, from North Bend, Washington,this one is a short distance away from Seattle, I’m hoping it stays cold through the weekend to venture out and see this in person.
From her blog:
“Ice Circles, or ice disks, are a natural phenomena where a thin layer of ice spins on top of flowing water. I heard through a Facebook post about an ice circle spinning on the Middle Fork Snoqualmie River close to where I live so I decided to check it out. I drove along the NF-5600 road peering over each bridge. I was elated to see that the circle was still intact and spinning. I spent the afternoon watching the slow rotations and listening to the murmurs of the ice. A few notches of ice were broken from the nearly perfect circle.”
A video as well to give you a true feel for this interesting phenomenon.
Excited to see the announcement of a new global design ideas competition from LA+ Journal, entitled Imagination.
“Paradisiacal, utopian, dystopian, heterotopian – islands hold an especially enigmatic and beguiling place in our geographical imagination. Existing in juxtaposition to what’s around them, islands are figures of otherness and difference. Differentiated from their contexts and as much myth as reality, islands have their own rules, their own stories, their own characters, their own ecologies, and their own forms.”
This design ideas competition asks you to create a new island. You can locate it anywhere in the world, program it any way you want, and give it any form you can imagine. The jury consists of Richard Weller, James Corner, Marion Weiss, Matthew Gandy, Javier Arpa and Mark Kingwell, and prize pool is $10,000 plus feature publication in the special issue of LA+.
Interesting exploration from Architect’s Newspaper from October covering a range of water specific projects and proposals in the urban realm. A short description:
“For landscape architects today, urbanism and water go hand in hand. Whether dealing with issues of sea level rise, groundwater retention, or just plain old water supply infrastructure, landscape architects are working with scientists, engineers, and policy makers on increasingly bigger projects that encompass more external factors and larger networks of physical, biological, environmental, and political networks. We examine some of these water landscapes and how they relate to each other in the broader context of how resources and climate-related changes are being managed.”
The grid locates these twelve projects in the field, with poles ranging on one axis from Decadence to Survival and on the other pole from Not Enough to Too Much. It’s a simple diagram that shows the complexity of water and the need for regional and adaptive solutions that address multiple problems but are also specific to place. This spans climate change, drinking water, development, and ecology — balancing all of the variety of needs for livability, economy and social equity of which water is intertwined. Check out the post for more detail, but a few highlights worthy of discussion.
The issue of climate refugees is going to continually be more and more common in the news. One such example is Shishmaref, Alaska who have “…asking whether it’s better to suffer the slings and arrows of outrageous fortune or take arms against a sea of troubles to combat a looming climate change–driven disaster.” While consultants have said they should stay, a recent vote went in favor or relocating the town, which is on an island in the Bering Straight, to the safer mainland, and they are looking for the $200 million necessary to do so.
Miami is an example of a much more populated city dealing with climate issue, such as flooding and access to clean drinking water, even when the city continue to grow rapidly. “Miami’s real estate value continues to rise despite the chronic flooding risks on its waterfront. Even as local governments pour millions into tackling high tides and storm surges, deeper economic and infrastructural issues loom as threats to growth and prosperity.”
Another interesting take on flooding, Chicago is looking at underground sand deposits that were built over, and still exist, to provide a unique resilience strategy. “The challenge is immense—for Chicago, one inch of rainfall equals four billion gallons. Until recently Chicago’s answer to the problem has been an infrastructure project no less than epic—read costly—in scale. But one landscape architect is leading an effort to change how the city can unlock its hidden potential for storm water management”
On the flip side, proposals for water scarcity are happening in Texas, through innovative methods of protecting supply, as well as creating controversy as cities in Wisconsin start asking to draw water from Lake Michigan.
And what review of water would be complete without some discussion of the contentious LA River, (banner image above) which is being tackled by multiple teams and has created some rifts in the design community, particularly that of putting Frank Gehry in charge of the latest public sceme. One postive from the Gehry team (in addition to including a good mix of other disciplinares) that I’m curious about is the “L.A. River VR Experience, an initiative by media producers Camilla Andersson and Anders Hjemdahl at Pacific Virtual Reality and FoLAR… The project is currently in the final stages of production and features a VR tour along the entire LA River. “
The work of Studio Gang to develop interdisciplinary solutions to ecological projects is interesting, and the work of UrbanLab also provides some context for water projects in China.
Lots more, so check out all of these brief articles and the matrix of abundance and scarcity and decadence and survival is a unique frame to look at water solutions. Finally, for more in-depth look at one of these projects, check out my post over at Hidden Hydrology to find out more on the Town Branch Commons project by SCAPE and the ‘daylighting’ of an urban waterway in Lexington, Kentucky.

I was really excited to receive the latest version of Pamphlet Architecture, published by Princeton Architectural Press. While I’ve not seen all of them, i do have at least a dozen, and they offer focused snapshots of theory and practice both as well as a longitudinal section of though spanning decades. My first experience was PA15: War and Architecture featuring Lebbeus Woods, which i picked up as an undergrad and was blown away. I’ve since picked up issues sporadically, including the great PA21: Situation Normal featuring the work of Lewis.Tsrumaki.Lewis (1998), PA23: Sites of Trauma with Johanna Saleh Dickson (2002), PA28: Augmented Landscapes by Smout Allen (2007), and PA30: Coupling featuring work and thoughts by InfraNet Lab and Lateral Office (2011).
I thought Bélanger’s essay ‘Synthetic Surfaces’ in the Landscape Urbanism Reader, was interesting, and was interested to see the work as well from he and others around this topic. For starters, some context, via the blurb snipped below on Amazon:
“”If landscape is more than milieu or environment, and encompasses a deterritorialized world, then it is the contested territory, hidden actor, and secret agent of the twentieth century. Stemming from the early work of some of the most influential landscape urbanists–Frank Lloyd Wright, Ludwig Hilberseimer, Benton MacKaye, Patrick Geddes–this mini manifesto explores underdeveloped patterns and unfinished processes of urbanization at the precise moment when environmentalism began to fail and ecology emerged between the 1970s and 80s. Informed by systems thinking from the modern atomic age, this slim silver pamphlet takes inspiration from Howard T. Odum’s big green book A Tropical Rain Forest and brings alive the voices of a group of influential thinkers to exhume a body of ideas buried in the fallout of the explosion of digitalism, urbanism and deconstructivism during the early 1990s. Catalyzed by Chernobyl’s nuclear reactor meltdown, a counter-modernity and neo-urbanism emerged from the fall of the Berlin wall and the end of South African Apartheid. What happened during this concentrated era and area of change–across design, from architecture to planning–is nothing short of revolutionary.”
The opening essays start provide some more context, and the crux is really what is said about the timing of the emergence of ecology in the 70s and 80s and how this is now fully integrated, after almost 50 years, into practice. I do want to find a copy of Odum’s ‘A Tropical Rain Forest‘ after reading the introductory info – perhaps the biggest gem this small volume offers.
Readers should be warned, this is not a trifle, but a dense exploration with a number of unexplained references and jargon – the kind of stuff that makes people roll their eyes and dismiss academic posturing as oh so much BS. Frankly the intro is probably one of the most annoying passages I’ve read in a while and the first sections were equally obtuse. It evens out a bit as you continue, but coupled with way too small text and only black and white imagery, it’s a bit of a slog. As in not enjoyable to read or engage in.
So if you’re still with me – check out the diagrams, and maybe read a section or two. When you get into them, are quite beautiful and the text has value – exploring some of the themes of landscape and infrastructure from Keller Easterling and Sanford Kwinter. Go to well lit room, with a magnifying glass and a lot of coffee and have fun.
I was initially put off by the reliance on only black and white imagery, as it seems anachronistic, more of a trope than a reason for its use in this particularly context. But they work and the idea of communication that transcends color – in these densely packed montages attempt to communicate a ton of info – sometimes it works, sometimes it doesn’t. Probably the best part of this volume – sometimes it’s amazing and you find yourself staring at a page for way too long. If they were 2x as big it’d be even better.
So as far as the takeaway for he at this point, I’m really intrigued by the graphics, and some of the experimentation. While i was initially put off by the black at white imagery, as i mentioned, but after looking at it multiple times, and viewing digital images, it does have a quality that perhaps obscured by our typical splashes of color.
Even as a pamphlet – the writings, well, I feel would have benefited greatly from a tougher editor that reined in some of the language and obscure references. I’ve read enough academic and dense writings that i can muddle through the most difficult, so I definitely don’t need my hand held. But there were so many opportunities to add one small explanation of a concept, rather than just leave the reader hanging, or googling, to understand some obscure reference or word choice. Belanger’s other writings didn’t seem so hard to parse. This was exhausting.
If you read it let me know what you thing. Got some ideas or thoughts. Let me know.
A cool use of art to activate some overpasses in San Jose, California by Seattle based artist Dan Corson. The first is called ‘Sensing WATER‘ which projects lighting on the underpass based on weather conditions. From the site:
Sensing WATER is a weather-responding and interactive artwork utilizing light and paint to define a major downtown gateway in San Jose CA. The project is composed of 2 elements, the massive painted sloped wall that abstractly references flowing water, and the overhead evening lighting that illuminates with rippling patterns of light the underpass of I-87. The project uses real-time NOAA weather data to compose different patterns of light on the ceiling. (e.g.: 0-5mph winds vs thunderstorms). The projected light maintains a similar palate to the painted sloped wall, yet becomes dynamic depending on the weather.
The use of real time sensing to activate the space, which sits atop the Guadalupe River. Corson was “… curious to link both the awareness of water issues to the new focus of the high tech industry through the use of dynamic illumination.”
Another take on the underpass is ‘Sensing YOU‘, which is more interactive, allowing users to control the patterns with an app/game from their cellphones. The goal in this case, like above, is also to “link technology and nature in this urban landscape sitting over the Guadalupe River- at the heart of Silicon Valley.” Some more info:
“Sensing YOU is an interactive artwork utilizing light and paint to define a major downtown gateway in San Jose CA. The installation is defined by over 1000 painted circles and 81 individually controlled illuminated rings that play a variety of patterns and low-resolution mapped video over the ceiling surface of the I-87 highway underpass. The patterns are activated by pedestrians and bicyclists moving through the space- setting off pre-programmed sequences.”

I recently gave a talk at the great annual conference Urban Ecology Research Consortium of Portland/Vancouver (UERC), which focuses on ” advance the state of the science of urban ecosystems and improve our understanding of them”. I was really excited to be chosen to present (i had done a poster presentation in past years), and it seemed a great way to introduce the Hidden Hydrology of Portland and what work has been done to date.
Much of this has been covered on the L+U blog – but there’s new ideas worth exploration, and some new momentum to realize some of the site-specific installations discussed here. A short visual recap:
My first experience with the concept was stumbling over the ‘Disappearing Streams’ map produced by Metro. Not sure of the vintage – but I remember seeing this easily in the late 1990s, and it’s stuck with me for years. Not actual streams but modeled topography generating basins – the concept is pretty simple – show what streams existed, and highlight those buried, piped, channeled in red, which is predominately on the inner east side and downtown.
A bit of digging yields a great set of maps, the Cadastral Survey of 1852 provides amazing detail of a nascent Portland, with stream corridors like Tanner Creek still intact running through downtown Portland, and other ecological resources (wetlands, lakes) as well as trails and early city grid (seen to the right)
A few folks share this passion, such as David James Duncan, who talks of disappeared streams in his book ‘My Story as Told by Water’ (2002) and historical account from folks like fellow Tanner Creek nerd Tracy Prince, who has authored some great accounts of the areas in Goose Hollow and Slabtown, evoking origins of place names, connections to hidden creeks, and tying this together with the rich history of Portland’s development.
Many layers interact in painting the picture of hidden hydrology. Photos are another great resource – with historic scenes of sewer creating, as well as floods and other historical events.
Beyond the Cadastral Survey, a wealth of maps exist, ranging from the mid 1850s through today – which paint a temporal portrait of the path of waterways over time – such as Tanner Creek, here shown still in existence in 1866.
And through an illustrative Aerial Lithograph here in 1870 – again showing the Tanner Creek drainage from the West Hills through the north portion of downtown.
Using these tools we can start to craft maps that take the historical and overlaying information – in this case a composite of Cadastral survey mapping, amended with other information, notes, and annotations – a layered history in map format. These could easily be hosted online (a future plan) for additional input and integration with stories, photos, experience.
The process of extracting this information from the survey – shown here in a few steps – involves 1) referencing the historical layers, 2) adding streams and other water bodies, 3) adding additional info such as wetlands and other topographic featueres, and 4) georeferencing and overlaying the historic with the current day mapping. A reverse map regression that allows us to create an interesting connection between then and now.
Because the Cadastral survey is based on the Public Land Survey System (PLSS) – the township, section, range geometry (see the faint orange lines in the map above allow the historic and modern to overlap with reasonable fidelity through cartographic rectification. The maps then, overlaid with GIS data – then digitized into shapefiles with linked data – start to allow us to provide some more detailed analysis – such as for instance, correlating basement flooding in proximity to old streams?
The second part of the talk focused on interventions – as the maps are compelling, but the ability to use them for actions are key, both in terms of expanding the validity of our interventions, but also to connect folks everyday to their hidden nature.
My colleague Matt Burlin and I have been talking about tours of the Hidden Hydrology for some time – so recently took the field maps for Tanner Creek and traced them from up towards the headwaters near Washington Park Zoo, down through the west hills and through downtown.
There are portions that still exist – albeit in a somewhat degraded form – but the visceral thrill of seeing this stream was compelling – The immersion in the sounds and experiences of these remnants is worth further visits.
And as you get to the urban sections, the natural remnants make way to a creek completely hidden – save a subtle topographic cue and some cultural interventions of markers and Tanner Springs Park, before getting to the current outfall location in the Willamette, near Centennial Mills.
How do we interact with that which is hidden, bringing lost layers of history back to the surface. Some great art installations provide inspirations that could be applied to hidden hydrology, for instance the Freen The Billboards project (which used fixed viewfinders to overlay images on billboards)…
Could be applied in zones to allow one to click through a series of images that show the stages of current, mapping, routing, and location of historical waterways – in this case a simple illustration of how this would work for Tanner Creek.
And drawing from the functional aspects of utility locates with the community artistry of intersection repair…
…one could imagine a meandering Tanner Creek weaving its way through downtown and northwest Portland streets, taking the idea of a couple of markers in the sidewalk to a much higher level of engaging and awareness in the underlying historical systems.
Thinking beyond a map or a kiosk with some informational interpretation, the array of interventions together provide multiple ways to engage, and coupled with technology could yield self-guided walking tours, vivid sound maps, and immerse multi-media experiences.
On a larger scale, the idea of Hidden Hydrology inspires thinking about community and our connections to each other. The concept of Neighborsheds, which i coined in the mid 2000s and presented at the ASLA National Conference about – involves using these natural drainages to redefine neighborhood boundaries. By rethinking political or cultural boundaries defined outside of natural systems, we can reconnect to our place in new ways. This knowledge is perceptual on one hand – but can engage folks in shared commitment – because if you’re in the neighborshed, all of your actions become innately connected in you cumulative impact downstream.
Finally, for me the concept of the Hidden Hydrology is tied to the larger ecological history. There is no better project to illustrate this that the Mannahatta Project (read more on a post here) which in it’s broader incarnation as The Welikia Project, takes the notion of historic mapping and blends field observations of biotic and abiotic factors in a rich and illustrative composite that is both rigorous and compelling.
My call to action, to create this detailed historical ecology for Portland, blending historical mapping with history, archaeology, anthropology, ecology, and other disciplines to paint a vivid picture of this historical ecology.
Beyond being fodder for art and culture, defining neighborsheds, or ways of engaging in urban exploration and wayfinding – there are some key opportunities available with this information. This can be inspiration for design interventions, can guide decisions about habitat, ecology, water, runoff, vegetation, and other factors, not in a general sense but in a block by block, historical watershed and stream basin scale.
The overlay and congruency with the hidden streams and our subsurface pipe systems is no accident – each are governed by system conditions of gravity. One is surficial and the other is hidden, so opportunities for making adjustments to the gray systems can be augmented with opportunities to use the green systems – with potentials for daylighting, integration of green stormwater infrastructure, and replication of pre-development hydrology. These decisions aren’t just based on current conditions (i.e. paved, permeable, landcover), but can be guided by understanding and modelling the pre-development hydrology – the best guide to how a particular basin wants to act by referencing how it worked before we altered it.
Finally, the concept of a pre-development metric is used for many things – to set stormwater management goals, to measure runoff in site and basin scales, and to set targets for sustainability for ecodistricts and other planning scale efforts. The return to the ‘native forest’ is a generalization of the pre-development condition, and also becomes a technological construct. Rather than pre-development condition, let’s thing of historical ecological function, which begins to not just provide us with numbers to meet, but also blends the vegetated, the ecological, the habitat, the cultural with the historic sounds, smells, textures, and colors the historical places before we forever altered them.
We won’t restore these to their natural state in all but a few selected places, but if we can restore, through metaphor, interaction, and intervention, the experience of these places, blended artfully with what they are now – places to live, shop, play – we reveal these hidden layers of inspiration to the urban experience.
A short video of the presentation is in development – and a longer follow-up, brownbag session is in the works – so look out for details.
A project of note that made the rounds over the past month resonated with the concept of Hidden Hydrology. The project ‘Ghost Arroyos‘, proposed as part of the Market Street Prototyping Festival paints the town blue, in a sense. I definitely like this idea, as we’ve discussed doing a similar exploration of Portland’s Tanner Creek.
From the Neighborland site description
“Every city has invisible histories embedded within its landscape. This project, “Ghost Arroyos” seeks to reveal the forgotten waterways of San Francisco through a simple, but powerful intervention. Situated between 7th and 9th street, the project will abstractly mark the footprint of Hayes Creek onto the urban surface. Visitors to the festival will be invited to trace the extent of the waterway while listening to a curated recording of hydrological soundscapes and oral histories”
Sounds much like the hidden hydrology proposals – and i’m curious to see it happen and what hurdles need to be overcome in implementation. Also, the soundscapes and oral histories are an interesting concept – that we’ve been exploring as well, so lots of great alignment to draw from.
Upper Yosemite Creek Daylighting
In digging into this project a bit, there was also a link to a proposed actual creek daylighting being proposed by the City of San Francisco is the Upper Yosemite Creek.
From the site: “The Upper Yosemite Creek Daylighting project will daylight the ephemeral historic Yosemite Creek to manage flows from 110 acres of McLaren Park. The creek will flow along the northern edge of McLaren Park from Yosemite marsh through Louis Sutter Playground and along the southern edge of University Mound Reservoir. The project will feature a creek channel to convey stormwater and alleviate localized flooding issues as well as storage and infiltration facilities. This project is the first creek daylighting project initiated by the City and will reintroduce natural habitat and provide opportunities for community learning and beautification.”
The reports are worth checking out – as it’s an interesting concept. The new ‘creek’ is a hybrid, while daylighting, the configuration, as seen above, interfaces with the built environment in a somewhat orderly manner and starts to look more like green stormwater infrastructure than natural waterways. This mediating between what was and the ‘functional’ aspects of the restoration is worth further exploration.
Two great examples from San Francisco on hidden hydrology in action.
Good article in the USGBC+ magazine related to Bioclimatic Design and some projects that focus on the integration of vernacular strategies (and forms) to increase responsiveness to the local environment in which they are built. This is nothing new for many designers, and builds upon centuries of knowledge, but I’m mostly interested in how it incorporates landscape and buildings in inventive new (old) ways.
The ability to transcend climate came with “…the advent of modern technology in the 20th century, contemporary design trends shifted away from being responsive to natural conditions and emphasized instead isolating buildings from nature to try to overcome those conditions.” As mentioned, this opened up new frontiers for where we could live, but also lead to homogenization and reliance on heating and air conditioning (or maybe even overbuilding in climates ill-suited for development). That said, bioclimatic design can include both the vernacular as well as rely on significant technological knowledge to realize – through modelling and other modern design tools.
The grass covered roof is a simple and archetypal form of the landscape and building integration – used for cooling and made from locally available, regenerative materials. Plus, goats for roof maintenance is pretty sustainable. This pre-cursor to the modern green roof was borne of necessity, but also perhaps can also aid in resilience and climate adaptive building strategies that start to creep into the vocabulary of designers – through the guises of biomimicry and biophilia. Both work hand in hand as there are inspirations from nature revealed in design, and the planet, as well as building/city users benefit in multiple ways. It’s a full circle of building based on our innate traditions beginning to feed our innate need for access to this nature.
A really stunning example of the process ( Autorité de Régulation de la Poste et des Télécommunications by Mario Cucinella Architects) is outlined in the article so i won’t go into detail, but has a subtle integration of landscape with building form.
The shape of the building is scooped to capture cooling winds, but the indigenous shape has additional benefit:
“Another influence on the shape of the building was a desert structure used in antiquity in many arid parts of the world, called a tu’rat, Bruno says. These crescent-shaped structures, made of stones piled without mortar, captured moist winds and fog, which created condensation that percolated down to irrigate protected gardens. “In the early morning, you can collect a little bit of water, and this allows you to grow plants,” he says. The tu’rat-inspired structure includes the enclosure of a small oasis of palm trees and other vegetation on the south side of the building.”
The relationship of water in the desert is key, and additional elements like rainwater collection and phytopurification, using a constructed wetland), will dramatically reduce water use while providing comfort and verdant respite.
A more urban example is RB12, a building in Rio de Janeiro design by Triptyque. Drawing from the bioclimatic concepts popularized by Ken Yeang, the building uses “Suspended gardens integrated into the façade, along with a green rooftop, also help control lighting.”
While ostensibly a form of climate control, in this case it is less successful, as there is supplemental systems for cooling, as mentioned, which makes it less of a bioclimatic model than one that is merely inspired as such. My thought looking at renderings is that they didn’t take it far enough, or integrated the vegetation thoroughly enough, to make it more than a few plants on terraces.
The ability to integrate buildings and vegetation – as i’ve called it vegitecture, is a key element for bioclimatic architecture, and offers many potential opportunities for designers to collaborate. The potential spans beyond the building-centric to also include potential for habitat development in the urban ecosystem, refuge for birds, and pathways for pollinators. All while cooling buildings and making cities more livable. Not bad.
