BBC environment analyst Roger Harrabin reports on the tower block under construction in China which could lead the way in green building technology.
THE GREEN TOWER OF GUANGZHOU CITY
A closer look at the Pearl River Tower: VIDEO HERE.
Rising high through the polluted air of Guangzhou City in southern China is a 71-storey tower block which, according to its designers, will be the most energy-efficient in the world.
Among a host of features designed either to make or save energy, the one that caught my eye was the shape of the Pearl River Tower itself.
It is built in a curve, facing the prevailing winds. And it has been deliberately sculpted to increase the speed of that wind and force it through slots in the building where wind turbines will be located.
Now, on many buildings, wind turbines are a waste of space because there's so much turbulence in cities. I heard an apocryphal story about a Japanese firm that installed a turbine which needed electric power to keep it turning to save the face of its would-be-green owners.
HOW THE TOWER SAVES ENERGY
- High temperature fuel cells complement the sustainable systems
- The outer skin controls glare and includes a photovoltaic system for energy
- Wind turbines generate power which can be fed to mechanical equipment
- The design incorporates a "high performance" building envelope
- An air displacement system relies on raised floors
- Cooling tower water passes through embedded tubes in the building
But the American architects of this tower - SOM - insist that their experiments in a wind tunnel show this building will generate economically viable wind power.
The vertical axis turbines will be located in the mechanical floors mandated by the Chinese government as emergency muster floors, so no usable office space will be lost.
SOM claims that by thinking carefully about the use of space combined with energy-saving and energy-generating technology, they have been able to make unprecedented gains, so this building will potentially create as much energy as it uses.
They are by no means the only architects to espouse the principle of integrated design, of course. But some observers believe that too many buildings are still being put up with a few bolt-on green features, without proper thought as to what could be achieved through a more considered approach.
Take the cooling system in the tower. Most of the time, air conditioning is done by fat air ducts which gobble both energy and space between floors and ceilings. Here the cooling is done by a cool water system.
The water flows in ducts through concrete beams, and cool air descends upon the toiling masses from cold water radiators in the ceilings.
This doesn't just save energy. SOM say it saves so much space that it's allowed the building's owners to put in an extra five storeys of usable office floor at little extra cost. Indeed, they predict that the extra investments in the building will start making the money in five years.
There are other green features too. There's a wide-spaced double-glazed wall, which channels hot air upwards to a mechanical floor where it's harnessed for dehumidification.
There's also substantial use of solar photovoltaic technology on the frontages of the building, which curve upwards toward the sun, although the current cost of photovoltaic arrays militated against cladding the building completely in energy-generating glass.
Inside there are numerous automatic control systems to make sure power isn't being wasted.
SOM say they could have coaxed the building to produce more energy but it would have been futile because there's no facility in Guangzhou to feed self-generated power back into the grid. To many, this will be a familiar tale.
'Radical' design
I can't verify whether all its claims are true, but the building is undoubtedly an exciting project.
Ame Englehart, director of SOM's East Asia office said: "This building is so radical it could only have been commissioned in China. The owners are very self-confident and have been prepared to push the design as far as it will go."
SOM insists that the design is site-specific and can't just be replicated elsewhere.
But the sad observation from my viewpoint standing on the girders of the 24th floor is that this tower is very much the exception rather than the rule.
The Chinese government has increased building standards recently but they still don't lead to anything like the performance of the Pearl River Tower.
A report in the China Daily during my trip suggested that 40% of bribery cases in China involve property development.
And a Western businesswoman I bumped into told me her firm couldn't persuade Chinese clients to invest in more energy-efficient vehicles even if she could prove that they would start paying back their owners in energy costs is just 10 months.
Later in the week I'll be looking at the building frenzy in the Chinese countryside. Tomorrow, though, I'll be looking at electric scooters in Guilin.

Effet d'annonce ou réalité? Le point frappant est que l'on recommence à dessiner des architectures dont la forme et l'organisation est (en très légère partie ici) déterminée par un design "climatique", à la façon des architectures vernaculaires. A suivre...

For the upcoming exhibition Contemplating the Void: Interventions in the Guggenheim Museum Rotunda 250 artists, architects, and designers were asked to imagine their dream intervention in Frank Lloyd Wright's rotunda. JDS' Julien De Smedt has created a proposal that begs to be realized. A spiraling orange trampoline mesh descends from the top of the rotunda, inviting guest to traverse, rest and play. Brilliant!

A week or so back, a bright guy I met at PICNIC named Lincoln Schatz asked me if I mightn’t list for him a few things I’d been reading lately. I got about halfway through before I realized that I was really compiling a manifest of books I’d been consulting as I put together the pieces of my own.
So this is for you, Lincoln – but I bet it’d also be particularly valuable for readers who are coming at issues of networked urbanism from the information-technological side, and would like a better grounding in sociological, psychological, political and architectural thinking on these topics. (There’s also a pretty heavy overlap here with the curriculum Kevin Slavin and I built our ITP “Urban Computing” class around.)
Not all of these were equally useful, mind you. Some of the titles on the following list are perennial favorites of mine, or works I otherwise regard as essential; some are badly dated, and one or two are outright wank. But they’ve all contributed in some wise to my understanding of networked place and the possibilities it presents for the people who inhabit it.
Two caveats: first, this is very far from a comprehensive list, and secondly, you should know that I’ve provided the titles with Amazon referral links, so I make a few pennies if you should happen to click through and buy anything (for which I thank you). At any rate, I hope you find it useful.
UPDATE 19 October 20.49 EEDT
Thanks, everyone, for the suggestions. Please do bear in mind that, as I noted, this is not a comprehensive list of interesting urbanist books, but an attempt to account specifically for those works that have been influential on my own thinking. With a very few exceptions, I’m no longer looking for new insights, but for ways to consolidate and express those deriving from my encounter with the works listed.
That said, I’ll continue to update the page as I either remember titles that ought to have been included in the first place, or in fact do assimilate new points of view.

Personal comment:
Adam Greenfield, théoricien et essayiste des questions liées à l'"urban computing", l'"ubiquitous computing", etc. publie ici une bibliographie liée à son prochain livre. Beaucoup de choses connues et de "usual suspects", mais aussi quelques noms qui le sont moins, tout au moins pour nous. Bonne ressource à creuser, si nécessaire.
Intéressant également de constater l'approche "ouverte" qu'adopte Greefield par rapport à son prochain livre, publiant régulièrement des informations ou des extraits à son propos, questionnant la "communauté" de son blog sur les thèmes abordés, etc.

I've been meaning to post more on this theme for a while - it's partly one of those entries that is really a 'note to self'. But when Timo Arnall and Jack Schulze posted their fascinating research into visualising the (otherwise invisible) characteristics of RFID last night, it prompted me to hit 'publish'.
Their research piece Immaterials is quite lovely, exploring the spatial qualities of RFID in terms of its readable volume, captured with a simple LED/sensor and camera. Here's their video, in which they explain more:
(As well as the conceptual backdrop, outlined in more detail by both Timo and Jack, I particularly like the care and attention they've given to the visualisation, and the presentation of the research. This is quality design.)
In their work I even see something of the early experiments of, say, Benjamin Franklin and Nikola Tesla in terms of understanding the behaviour of electricity, such that it can then be tamed, conducted, and put to work. It's perhaps drawing a long bow to make that comparison, but it feels like a similar sentiment. Whilst electricity is hardly invisible, there is a sense of trying to understand such immaterial phenomena through prototyping and experimentation. (And again, while some would see that as the province of science, it's also the contemporary purpose of design.)
(In this particularly fine image, we see Tesla's friend Mark Twain conducting high-frequency high voltage current, bringing a lamp to incandesce. Tesla is lurking in the background.)
Part of the purpose behind Immaterials is to understand more about RFID in terms of an emerging 'material knowledge', as Timo put it, from the designer's perspective. But perhaps also in order to raise awareness of a technology which is essentially invisible - and often feared - such that we can better understand it, and so make informed choices. It's similar to my own far sketchier work exploring the shape of the wi-fi at the State Library of Queensland (written up here) - if you could perceive the phenomenon of wireless internet as a physical space, what might it look like? (It'd be more interesting to ask what it feels like, actually.)
Despite the fact that it suggests the already massively overused term "making the invisible visible", I'm particularly interested in tapping into the content in such transactions, as well as their materiality/immateriality, as a way of understanding patterns of behaviour in what I'm calling the new soft city.
Closing the loop then means finding a way of exhibiting these invisible phenomena back in physical space. In an email exchange with Jack last night, I suggested that we might see such blooms or halos sparking as transit card-carrying passengers walk through ticket barriers in subway stations (I'm currently working on informatics for a subway project; it was front-of-mind). Jack had already put it thus:
"Having produced these visualisations, I now find myself mapping imaginary shapes to the radio enabled objects around me. I see the yellow Oyster readers with plumes of LED fluoro-green fungal blossoms hanging over them – and my Oyster card jumping between them, like a digital bee cross-pollinating with data as I travel the city."
As well as the wi-fi research, I've also been fascinated by capturing existing everyday examples of how the city assesses invisible or hidden characteristics of its infrastructure.
I've been taking photos of people who appear to be sensing the city - in the broadest, er, sense of the phrase. The following shots are from Sydney and Los Angeles, and indicate the more quotidian, prosaic activities involved in instrumenting and monitoring the city - from surveyors to telecoms operators, from vans counting passing traffic to guys probing underground pipes, from markings on streets indicating what's underneath to this peculiar footage of what looks like someone using a sonovac but is probably just a device checking for cables.
I've created a public group at Flickr called Sensing the City, so if you have similar photos, do add them there. I'd be interested to see what turns up.
While it's a very different sensibility and approach to the aforementioned explorations of radio frequencies - it's often a very material city, rather than immaterial; just hidden - in the context of discussions around instrumenting the fabric of our cities via urban informatics it's interesting to consider how much of this already occurs on our streets. And despite being marked by traffic cones and fluorescent work jackets it's become an invisible activity, somewhat ironically, for passers-by. These people are sensors.

Personal comment:
Pour faire suite aux posts précédents ... Développé sur l'essai de Timo Arnall.
I see that Dan Hill put the post from the Toward the Sentient City exhibit up at City of Sound, and that version improves on the version at Toward the Sentient City by including links and images. Reading Hill’s post again, I noticed a couple paragraphs that bear on the post below regarding architecture and “urban systems design”, which I’ll quote at length:
Gregory Weissner’s introduction indicates that the show is “intended to bring architects and urban designers into a conversation that until now has been limited largely to technologists.” He continues:
“Don’t be confused by the technology (and the terminology), though. What we are talking about is nothing short of a complete reorientation of our relationship to the built environment and the unintended consequences are not going to be all positive. Either architects and urban designers insert themselves now into the discussion about how these technologies are conceptualized and deployed or they risk diminishing the unique contributions they bring to shaping our world.”
Architecture and urban design should be in this debate, no doubt, but its entire practice, sensibility and economic model may need redressing (as with many other fields, of course.) Given their previous predilections, the lack of technical and conceptual understanding - never mind an apparently congenital inability to design a decent website - the profession has a long way to go before it can demand a seat at the table. An admittedly fading tradition of thinking of itself as the ‘master builder’ needs to be entirely excoriated once and for all. Devising the architect’s new sensibility - what Paul Dourish would describe as “the designer’s stance” for the discipline - will also be fundamentally important. Either way, complex urban systems are well beyond the ken of the sole master builder; they have been for years, but increasingly so with this ever more multi-layered understanding of the city.
Other design disciplines - interaction design, industrial design, service design, to name three - are currently far better placed to lead on these ideas, within multidisciplinary design teams. So the architect may be best-placed as part of that team, leading on spatial intelligence just as others might lead on information and communication systems, materials, structures, embodied interaction, behavioural psychology, topography, acoustics, biodiversity and so on. In a recent conversation with the SENSEable City Lab’s Carlo Ratti, we ended up sketching out a loosely multidisciplinary team in which the architect was one of perhaps ten different disciplines, all of whom would lead at various points.
Which reinforces my impression that the architect’s role in future design conversations will have less to do with a particular kind of technical expertise (as Hill points out, architects are way behind technologists in developing the technical expertise necessary to design for a sentient city) and more to do with a peculiar way of thinking (or kind of intelligence). Doesn’t do much to explain why the “spatial intelligence” architects provide is particularly useful or important, but when architects are conversing with themselves, that’s probably less important than pointing out disciplinary deficiencies.
