J. Scott Turner was interviewed by host Steve Curwood on the public radio program Living on Earth last weekend. A physiologist by training, Turner is interested in how the structures animals build can function like living organs (in fact, that was the subject of his
first book,
The Extended Organism: The Physiology of Animal-Built Structures). This interest has taken him to Namibia, where he studies the energy flows of termite mounds, research that has some surprising applications for human-built structures. It turns out the self-cooling properties of termite mounds are being tapped to create green buildings that use turbulent wind energy to control temperature and humidity.
From the
transcript:
...The secret of being able to do this for all buildings is to be to reproduce the complex structure that enables termites to do this. So, our thinking is that if you can somehow replace impermeable walls with these kinds of structures that can actually tune the inconvenient energy that's in turbulent wind, then you're opening the door to, I think, a revolution to the way we think about wind technology. You can have not only ventilation for free in any building, but we're working on designs that can enable the control of humidity, perhaps even wind-powered air conditioning in ordinary buildings. So, mainly by exploiting this untapped band of wind energy that's out there.
There are more than a few people interested in the connections between animal nests and human architecture. They met up earlier this fall at "From Insect Nest to Human Architecture," a
conference in Venice sponsored by the European Center for Living Technology. Biomimicry used to mean fasteners modeled on gecko's feet--now it goes large scale.
I'm looking forward to seeing the shape of things to come. In the meantime, I'm enjoying peeks at what that future might look like, courtesy the
Eastgate Center in Harare, by architect Mick Pearce, which already is putting termite engineering principles to work, and
this fascinating design by visionary and pioneer of "evolutionary architecture" Eugene Tsui for a two-mile high building that looks an awful lot like a termite mound. If filmmaker Hayao Miyazaki designed buildings, I think they might look something like this.
