Looking for the future of housing at the Solar Decathlon in Madried

Posted on by

Check out three designs from an international housing competition in Madrid: a “Heliomet SunBloc” house, the Bee House, and a house made out of recycled wood and mushroom spores:

London Metropolitan University’s “Heliomet SunBloc” European Solar Decathlon house combines novel construction methods with unusual materials. The house is designed so that it can be placed on the rooftops of existing buildings or other disused areas, answering a difficult question about future suburban growth. Allied with a PV-T (PhotoVoltaic-Thermal) array, the design would help supply electricity and hot water not only to its own structure, but to the host building as well.

The primary material consists of relatively low-cost and lightweight EPS foam that allows unique interior and exterior designs to be created. …

The Bee House … makes extensive use of living walls and green roofs planted with bee-friendly vegetation. This built-in beekeeping system, completed by a backyard hive, serves to pollinate the home’s surrounding garden areas, which keep the homestead stocked with homegrown veggies as well as honey. The Bee House includes a work area and boutique shop where honey and beeswax-based soaps and candles can be sold to the public, perfect for the urban farmer with an entrepreneurial bent…

To say that this house is aspirational is putting (it) lightly, as the structure can’t currently be built as designed — largely because it’s constructed around a wall system based on recycled wood that has been colonized by mushroom spores. The myco-treatment, so to speak, creates a fire- and mold-resistant, highly insulating building block ideal for green building. Oh, and it produces two edible mushroom crops in the process. (Call it the 100 Mile House meets the 100 Mile Diet.)

We are probably a long ways from seeing any of these three designs in practice. However, they do hint at some possible trends:

1. Greener houses. I think the question is how far builders and buyers are willing to go. Far enough to save a little money? Enough to significantly increase the price/value of the home?

2. Trying to utilize and connect to nature. Many single-family houses are sort of sealed off from nature even if they are in more suburban, idyllic settings. This could include everything from an uptick in gardens and compost piles, using green roofs, providing more rooms that don’t feel so sealed off from the outside, or just harnessing nature for energy purposes (solar plus geothermal and other options).

3. Looking for ways to build homes in denser settings. One assumption made by a number of thinkers is that future homes and suburbs will be more dense due to rising energy costs (particularly an increasing cost in driving due to higher gas prices and possibly higher gas taxes to keep up with better fuel efficiency) and young adults and retiring adults who want walkable communities as well as places that offer mixed-uses and more of a neighborhood feel.

Weeds, lawns, and “turfgrass subjects”

Posted on by

A review of a new book about weeds mentions the work of a geographer who calls lawn-happy Americans “turfgrass subjects”:

Mabey shows how attitudes to “weeds” reveals so much about human society, most notably perhaps in the nightmare of the American lawn – a toxic monocultural sward, saturated with chemical weedkiller and fertilser (more used per acre than on any crop) that occupies from 50,000 square miles (about the size of Iowa) and on which more than $30billion a year is spent. Mabey explains the origins of suburbia with Frederick Law Olmsted, a landscape architect established one of the first planned communities in 1868, laying out rules saying that each house had to be set 30 feet back from the road, and any exterior divisions were banned. Mabey notes: “The sociologist Paul Robbins has coined a term for the suburban victims of the combined pressures of national tradition, neighbourly prissiness, commercial gardening pressures, and the insistent identity, the integrity, of the lawn itself. He calls them ‘Turfgrass Subjects’.” Mabey notes how this is taken to extremes in Houston, Texas, where by-laws make any weeds “illegal”, defined as “‘any uncultivated vegetable growth taller than nine inches’ – which makes about two-thirds of the entire United States’ indigenous flora illegal in a Houston yard”.

We subject ourselves to tending our lawns, through thick and thin. Is it all really about feeling like we have some mastery over (a very very small piece) of nature?

It would be interesting to consider further the war metaphor that is used regarding weeds: we wage war on weeds in order to emerge victorious. In the long run, can we win the war on weeds? This may not really matter for our lawns but it could have a huge effect on agriculture…

Robbins has a full book about the lawn: Lawn People: How Grasses, Weeds, and Chemicals Make Us Who We Are.

The disappearing natural world in children’s books

Posted on by

A new sociological study suggests the natural world is disappearing from award-winning children’s books:

A group of researchers led by University of Nebraska-Lincoln sociologist J. Allen Williams Jr. studied the winners of the American Library Association’s prestigious Caldecott Medal between 1938 (the year the prize was first awarded) through 2008. They looked at more than 8,000 images in the 296 volumes.

They noted whether each image depicted a natural environment (such as a forest), a built environment (such as a house), or a modified environment (such as a cornfield or manicured lawn). In addition, they observed whether the illustrations contained any animals, and if so, rated them as either domestic, wild or anthropomorphized (that is, taking on human qualities)…

Specifically, they find images of built and natural environments were “almost equally likely to be present” in books published from the late 1930s through the 1960s. But in the  mid-1970s, illustrations of the built environment started to increase in number, while there were fewer and fewer featuring the natural environment…

“These findings suggest that today’s generation of children are not being socialized, at least through this source, toward an understanding and appreciation of the natural world and the place of humans within it,” Williams and his colleagues conclude.

Here is the list of Caldecott winners. Here is what the award is about:

Each year the Newbery Medal is awarded by the American Library Association for the most distinguished American children’s books published the previous year. However, as many persons became concerned that the artists creating picture books for children were as deserving of honor and encouragement as were the authors of children’s books, Frederic G. Melcher suggested in 1937 the establishment of a second annual medal. This medal is to be given to the artist who had created the most distinguished picture book of the year and named in honor of the nineteenth-century English illustrator Randolph J. Caldecott. The idea for this medal was also accepted enthusiastically by the Section for Library Work with Children of ALA and was approved by the ALA Executive Board.

Do Newbery winners (chapter books) have more depictions of nature?

Perhaps this is simply the necessary consequence of suburbanized America. How many children actually have consistent opportunities to interact with nature or even to see it? The suburban world is a strange one in that while it has a lot of natural imagery (think of street names) and the first suburbs of the mid 1800s invoked pastoral themes, the natural world is very homogenized and sanitized.

Additionally, we live in a country that suggests technology can improve or solve most problems while nature might seem somewhat static (even though it is incredibly dynamic). Perhaps we are now a culture where only the built environment promises excitement while nature seems unpromising. Or perhaps pressing social concerns simply tend to outweigh natural concerns at every turn.

While this study can’t conclude whether these books are reflecting cultural concerns or forming cultural ideas, it does raise questions about what children’s books should be doing. Teaching valuable lessons? Passing along cultural values or cultural capital (a la Bourdieu)? Entertaining? Helping kids learn to read and learn about the world? Making money for the publishers? All of the above?

I wonder if any of the Caldecott Award committees thought about the role of nature in the books they selected.

(This study seems a bit similar in methodology to a study last year that looked at gender biases in children’s literature.)

Crumbling McMansions as “wildlife habitats”

Posted on by

Mix together a few recent stories about animals encountering people in the suburbs and you can reach an interesting conclusion: McMansions could become “wildlife habitats”.

Great news for folks who have watched the value of their exurban McMansions circling the drain over the past few years: These fringe habitations can be returned to nature to find new life as wildlife habitats. It’s basically the real estate version of composting.

Okay, so there’s not really an official effort to make subdivisions into sanctuaries, but apparently nobody told bears that. In Hopatcong, N.J., a cable TV repairman recently descended into 85-year-old Frank Annacone’s basement and found a 500-pound black bear slumbering there. The folks at Gothamist dubbed it the “Reverse Goldilocks Bear,” and in a true case of lopsided justice, it was quickly tranquilized and subjected to an “examination” (yikes) before being released back into the wild. (What did Goldilocks get, a good scare and a few hours of community service?)

It’s not the first time wild animals have done the “creative reuse” thing on the outer edges of civilization. BldgBlog has dredged up tales of bobcats lounging around foreclosed exurban mansions, bees that turned a California home into a honey factory, and a pack of coyotes that squatted in a burned-out house in Glendale, Calif.

These sort of animal/human interactions are no small issue in some suburbs. In this area, discussions about coyotes were hot not too long ago.

Trying to imagine McMansions as wildlife habitats is an interesting exercise. One far-fetched solution: some wealthy activist buys up a large McMansion neighborhood and turns it into a preserve. Perhaps people would even pay money to tour the odd preserve. This sounds like it could be a Hollywood thriller where some poor visitors end up trapped in this dystopian world. (Imagine Jurassic Park without dinosaurs and in a neighborhood of crumbling McMansions.) A second option: someone creates art that depicts crumbling McMansions returning to nature and full of animals.

If anyone has images or stories of full neighborhoods that have been “returned to nature,” I’d be interested in seeing them.

The limits of GPS in the West

Posted on by

Technology can be a good thing but it can also lead people astray. Hence, a warning out West regarding using GPS in certain areas:

Travelers in the western U.S. should not rely solely on technology such as GPS for navigation, authorities said, after a Canadian couple were lost in the Nevada wilderness for 48 days.

Albert Chretien, 59, and his wife Rita Chretien, 56, sought a shorter route between Boise, Idaho and Jackpot, Nevada during a road trip from British Columbia to Las Vegas…

Sheriff’s offices in remote, high-elevation parts of Idaho, Nevada and Wyoming report the past two years have brought a rise in the number of GPS-guided travelers driving off marked and paved highways and into trouble.

The spike has prompted Death Valley National Park in California to caution on its web site that “GPS navigation to sites to remote locations like Death Valley are notoriously unreliable.”

When two roads diverge in Western lands, take the one more traveled, authorities said.

Perhaps this could be read as a warning about over-reliance on technology: it is not infallible.You can occasionally find stories of people driving into retention ponds or crashing into things because the GPS told them to turn. At the same time, how bad are these GPS maps that people can get lost so easily? This would seem to be bad news for GPS makers if they don’t cover certain areas very well. Could a GPS maker ever have any liability for any of these unpleasant occurrences? Additionally, I wonder how many GPS owners also carry around a map of some kind in their vehicle or on their person.

More broadly, this is a reminder that one doesn’t have to travel very far to leave the comforts of the modern world and get lost in nature.

Bringing nature back to the city while still accepting cars and suburbs?

Posted on by

In modern history, the city has often been seen as the antithesis of nature or the countryside. With dirty factories, a multitude of noisy vehicles, and buildings crammed on top of each other, Americans (and others) responded in part by moving out from the city and into suburbs when the opportunity arose.

But there are still arguments about whether nature can return to the city and what exactly it might mean:

The following lies at the heart of the agenda of a growing number of designers and architects who refer to themselves as “landscape urbanists”: “the notion that the most important part of city planning is not the arrangement of buildings, but the natural landscape upon which those buildings stand.”…

“Proponents envision weaving nature and city together into a new hybrid that functions like a living ecosystem. And instead of pushing people closer together in service of achieving density … landscape urbanism allows for the possibility of an environmentally friendly future that includes spacious suburbs, and doesn’t demand that Americans stop driving their convenient cars. Americans have decided how they want to live, they argue, and the job of urban designers is to intelligently accommodate them while finding ways to protect the environment.”

And that’s the rub—the bit about cars and “spacious suburbs.” Architects who believe that a fresh commitment to urban living offers the best path to a sustainable future are deeply disconcerted by this quasi-green rhetoric, and by the way it’s catching on at trendy architecture schools. They call it a “a misguided surrender to suburban sprawl.”

This is part of a larger debate about land, density, lifestyles, and government funding: can we be truly “green” as long as there are any suburbs and cars? It sounds like one side says we need to compromise with the pro-suburban forces in America while another is holding out for a more urban world. Such a dividing line affects issues including sprawl, gas taxes, land use, high-speed rail, and more.

I’m not sure why it has to be an either/or question. Cities could adopt different tactics. Is Central Park a failure because it is compromised by several roads running through it? This seems more like an ideological battle rather than a discussion about what could happen in American cities in the near future.

National Geographic amateur photo contest pictures

Posted on by

I wonder how many Americans would count photography as a hobby. In today’s world, it is easy for the average person to buy a decent camera and shoot some decent photos. To see some of the best of these photos, check out this photo collection of 13 pictures from National Geographic’s annual amateur photo competition.

I have always enjoyed the photographs in National Geographic, pictures of nature, places, and people. In this particular photo collection, I like #13 the best, the picture of a supercell thunderstorm. That thunderstorm looks like some weird spaceship has just lifted off.

Quick Review: The Cove

Posted on by

On the surface, The Cove is not a typical film that I would watch: a documentary about nature. But I found The Cove to be engaging. A few thoughts about this award-winning 2008 documentary:

1. The story follows the actions of Richard O’Barry as he tries to expose the slaughter of dolphins in a protected cove in Taiji, Japan. O’Barry’s backstory is very interesting: he was the trainer for Flipper but immediately switched sides to protect dolphins after one of the show’s dolphins died (he says she committed suicide) in his arms. O’Barry assembles a team of people to help expose what is going on in Taiji as some in that community attempt to stop him. To me, O’Barry is the heart of this film – his decision and actions to try to save dolphins shows remarkable dedication and stubbornness in the face of difficult odds.

2. It is hard not to like dolphins: they are intelligent and are graceful. But O’Barry suggests one part of their appearance that may work against them: they appear to humans to always be smiling and this masks the times when they are in pain or are suffering.

3. Why do whales and dolphins get all of this attention, both in this film and from zoo or aquarium attendees? There are plenty of animals that are mistreated and locked up. There has to be an interesting social history here.

4. One of the side plots in this film is Japan’s role in the International Whaling Commission. This international body has difficulty stopping Japan from doing anything. Again, this could be a whole story or film in itself: how Japan skirts international law and advisories to conduct whaling activities.

5. One strong point of this documentary is that O’Barry’s team actually attempts to do something (and it is set up like the plot of some action film) as opposed to documentaries where people talk the whole time and viewers are shown statistics.

Overall, I enjoyed this film: the fight against what happens in Taiji, Japan makes for an interesting tale.

(This film was highly rated by critics: it is 96% fresh at RottenTomates.com with 116 fresh reviews out of 121 total.)

Six reasons for living in the country versus in cities

Posted on by

The Yahoo Green blog provides a list of “six amazing things city dwellers miss out on.” Here are the six items on the list: stars, fresh air, peace and quiet, greenery, sounds of nature, and animals and wildlife.

It is interesting to think how many cities have created spaces where city dwellers can get glimpses of these things. Many large cities have large parks (think Central Park or Grant Park or the Golden Gate National Recreational Area) where some of these things are possible. However, as this blog suggests, seeing the stars even in the suburbs or thinking about city wildlife versus country wildlife is quite different.

To have all six of these things, how far would this blog suggest one has to move from the city? And for most Americans, how would these six amenities rate against the amenities that cities offer?

Opinions on science derailed by poor online sample?

Posted on by

Scientific American and Nature recently joined forces to poll readers around the world about their opinions of science. The findings include opinions about science and politics, climate denial, nuclear power, the flu and more.

While this data seems interesting, it might be questionable due to the sample:

More than 21,000 people responded via the Web sites of Nature and of Scientific American and its international editions. As expected, it was a supportive and science-literate crowd—19 percent identified themselves as Ph.Ds. But attitudes differed widely depending on particular issues—climate, evolution, technology—and on whether respondents live in the U.S., Europe or Asia.

So the findings may really be about the opinions of a more “supportive and science-literate crowd” rather than a true representation of international opinion. This is a common issue with open online surveys: it is very difficult to get a sample that is representative of a larger population.
