This Week in Prototype News

January 4th, 2010 by snugganut

The big blizzard of ’09 temporarily put the kibosh on construction, but we’re back up and running.  The Hemcrete forms have come off of the first floor, Serious Materials windows have arrived, and the roof is moving forward, with horse drawn, local, sustainably harvested hemlock fascia boards from Mountain Works installed this week.

If you’re interested in volunteering for the Nauhaus Prototype Project, please contact Billy.

Humanure: Goodbye, Toilets. Hello, Extreme Composting

December 12th, 2009 by brinker
(From Time Magazine)
By Adam Fisher Friday, Dec. 04, 2009

David Bailey helped install a composting toilet in Austin. Sawdust is used to eliminate odor.

For more than a decade, 57-year-old roofer and writer Joseph Jenkins has been advocating that we flush our toilets down the drain and put a bucket in the bathroom instead. When a bucket in one of his five bathrooms is full, he empties it in the compost pile in his backyard in rural Pennsylvania. Eventually he takes the resulting soil and spreads it over his vegetable garden as fertilizer.

“It’s an alternative sanitation system,” says Jenkins, “where there is no waste.” His 255-page Humanure Handbook: A Guide to Composting Human Manure is in its third edition and has been translated into five languages, but it has only recently begun to catch on. His message? Human manure, when properly managed, is odorless. His audience? Ecologically committed city dwellers who are looking to do more for the earth than just sort their trash or ride a bike to work. (See reusable toilet wipes as one of the top 10 odd environmental ideas.)

“It’s one of those life-changing books,” says Erik Knutzen, 44, an eco-blogger in Los Angeles. “You read it, and the lightbulb just goes on.” Now he eschews his porcelain potty for a big bucket with a toilet seat. He “flushes” by tossing in a scoop of sawdust, which not only neutralizes smells but also helps speed the breakdown of material for compost. Like many back-to-basics sophisticates, he believes Jenkins’ humanure system is more sanitary and more rational than the conventional alternative. “Human waste is a perfectly good source of an important resource, nitrogen,” Knutzen observes. “Water is a valuable resource too. Why mix the two and turn all of it into a problem?”

Wastewater treatment is much more energy-intensive than composting, which needs little more than time (about a year) for complete decomposition and pathogen elimination. In Austin, Texas, a sustainably minded nonprofit called the Rhizome Collective succeeded this year in getting the city to approve what may be the first legal composting toilet in the U.S. “The hypocrisy is amazing,” says Lauren Ross, 54, a civil engineer involved in Rhizome’s four-year battle to get a permit. “The city will buy you a low-flow toilet, but they’ll fight you all the way if you want to build one that uses no water at all.”

It’s an idea that you, dear reader, might be asked to take seriously. Not long ago, Nance Klehm, 44, a self-described radical ecologist in Chicago, invited her neighbors to stop using their toilets and start saving their poop. More than half of them — 22 of the 35 households — accepted her proposal. In three months she picked up 1,500 gal. (5,700 L) of excrement, which she’ll give back to participants this spring after she and Mother Nature have transformed it into a rich bag of fertilizer. “I’ve sent a sample in for a coliform test,” Klehm says. “There is zero detectable fecal bacteria.” (Read a brief history of toilets.)

At one point, Klehm invited her “nutrient loopers” to a potluck and was surprised to see who had agreed to participate. “It was the white collar people, not the ragtag anarchists. Mostly, they were delighted that they got this wacky proposal,” she says. “They didn’t know how to connect with the earth, but they could s___ in a bucket.”

Meanwhile, over in California, the Marin Composting Portable Odorless Outhouse Project, a.k.a. MCPOOP, is doing Klehm one better. The goal of MCPOOP (which is pronounced the Irish way as opposed to the rap-star way) is to get the government into the night-soil business and put humanure toilets in county parks and town squares. The group is less than a month old but already has the support of the local environmental establishment and Marin County supervisor Steve Kinsey. “The whole thing is like a good acid flashback,” says Kinsey. “We approved several experimental permits like this in the ’70s.” He estimates that a small-scale municipal demonstration project could be under way in less than a year. (Read “Is It Time to Kill Off the Flush Toilet?”)

MCPOOP was founded by a couple in their 50s. “We’re on a mission to re–potty train America!” says John Wick, a rancher in the western part of the county. “We’re going to start by replacing those nasty blue loos,” says his wife Peggy Rathmann, referring to two chemical toilets on their town’s main square. If that goes over well, they’ll replace the chemical toilets around Tomales Bay that kayakers often use. And then, who knows? Wick and Rathmann don’t see why every home in Marin County shouldn’t be humanure equipped.

To Joe (Mr. Humanure) Jenkins, nothing could be better news. “On a small scale, my system works like a dream,” he says. “But in order to do more research and development, I need to to collect humanure on a larger scale.”

MCPOOP and other projects are eager to help on the supply side. “We’re going to have plenty,” predicts Rathmann. “Tons of tourists come to West Marin, and they all leave us their poop!”

Hemcrete Installation Continues/ Mountain Works Stops By

December 10th, 2009 by snugganut

The Hemcrete installation continued today in the freezing weather, and is up to the second floor.  Ian Snider from Mountain Works dropped by yesterday to discuss some of the sustainably harvested wood he will be supplying to the project. Ian’s company uses horses to remove the trees that they selectively cull as part of a forest stewardship process.

Eco-Panels Installed

November 19th, 2009 by snugganut

Eco-Panels came out on Tuesday and Wednesday and installed the S.I.P. roof.  The finished roof system for the Nauhaus Prototype will have an insulation value of about R80 when completed, because the spaces between the 8″ rafters will be packed with cellulose.

Some information about Eco-Panels, from their website:

For a truly superior building envelope Eco-Panels manufactures the only R60 panel on the market today coming in at just 8.5″ in thickness.  This panel, designed specifically for use in arctic regions, is perfect for the passive house or net zero energy designs where most modeling software calls for an R40 wall and R60 roof (of course this will vary based on region).  This roof panel will perform at better than R60 at 20deg F (-7deg C) using LTTP (long term thermal profile) and temperature vs k-factor performance data provided by the foam component manufacturer.

  • 8 1/2″(21.6 cm) = R60+
  • Maximum panel length is 12′-0″ (360 cm) although this can be increased to 16′-0″ for large opportunities
  • Maximum panel width is 4′-0″ (120 cm)
  • The insulation is high-R-value polyurethane foam injected at a density of 2.5 pounds per cubic foot.

White Earth Reservation Cordwood home

November 17th, 2009 by Strongwood
Built by Bill Paulson

Cordwood Bear Paw for Native American owner

In the spring of 2008 the Midwest Minnesota Community Development Corporation made contact, to inquire as to the possibility of building a cordwood home on the White Earth Reservation in NW Minnesota (50 miles east of Fargo, ND). The original idea was to build a daycare and early childhood center and a home, but, for various reasons the home came first.

Anishinaabeg Cordwood Crew 09

Anishinaabeg Cordwood Crew

After many, many months of consultation and conversation, we were on our way to Naytahwaush to begin construction on September 22, 2009. The General Contractor, Robert Zahorski of Clearwater Building and Design was ready with the foundation (radiant in floor heat in a sand bed, using off peak electric hours—3 cents a KW); post and beam cedar frame, 12/12 pitch roof with 2 large bedrooms and a half bath and storage (shingled), a well, a mortar mixer, mortaring supplies and power!) What a great guy to juggle all these parts of the project.
The Native American Group Leader Bill, had been working to gather a cordwood masonry crew. Bill is a very talented individual with a skill set that defies description. Needless to say, he and Robert became our confidants and close friends. We are grateful for time we shared with them and the crew. The staff at MMCDC was most excellent in providing everything needed to make this a success.

Thwart the Diabolical Extraterrestrials: Buy Local Paint

November 5th, 2009 by Renee

This is the tenth in a series of articles for the New Life Journal.

By: Clarke Snell

Are you going insane like me? Do you ever sit in a parking lot and imagine the forest that used to be there? Do you ever look at the eastbound river of cars while you’re flowing westbound and ask yourself, “Where are we all going? Why can’t they stay where they are and do what I need to do there, while I stay where I am and do what they need to do here?” In the deep of night while the bedbugs bite, do you ever ask yourself, “What do rabbits know that I don’t?”

Yes, I must be crazy. So crazy that I’m completely baffled by how we humans come to find ourselves in the present world of our making. I’m so bent that to me we seem to be the only critters on the planet that can’t go with the flow. You know: live, eat, have babies, die, become compost for plants that are in turn eaten by our babies…repeat cycle. Is it my demented ramblings, or is our obsession with experimentation and childish competition grinding us to dust? Here’s my call for entries to all scientists, priests, freaks, and super-models: What the hell are we doing here?

My favorite theory about the existence of human life on planet earth is that we were seeded here by extraterrestrials. Sort of like bees making honey, they knew that we’d bring all the raw materials of the planet to the surface, process them into useful compounds and units like plastics and alloys, then concentrate them in piles (cities, landfills, etc.) where our masters could then easily harvest these goodies for their own use. If this process eventually killed the worker drones (us) or adversely effected the lifecycles of the planet itself, that would be of no concern. The point was efficient resource extraction. Though admittedly ridiculous and based on no facts (sort of like our present foreign policy), this theory has a compelling internal consistency and does offer an explanation for certain strange human behaviors such as packaging small amounts of water in plastic bottles. At the very least, it allows us to feel like we’re doing a good job.

Whatever the origin of our shenanigans, we’ve become so intransigent that the planet itself seems to be trying to throw us off. That’s the image that scientist James Lovelock used in an interview I heard recently. He said that humans have become an invading virus on the organism that is planet Earth. Global warming is the response, the fever attempting to combat the virus. The earth, though, is in the latter stages of its life, and therefore, like any senior citizen, may not be able to survive the fever.

Gawd. The more it all sinks in, the more I understand Disneyworld: Attention Citizens, just don’t think about it and watch the big mouse with the white gloves… I mean, how do we stop being a virus!?

Well, I’m no genius, but one thing I can do is pay attention. When you do that, you start hearing a lot of good ideas. Here are a few: Let’s not drive lettuce in from California when it’s being grown right here. Let’s not drive wood in from Oregon when it grows right here. Let’s not drive paint in from who knows where when it’s made right here….What?

That’s right, if you live in the distribution area of this magazine, you have access to locally made, non-toxic, environmentally conscious paints, masonry sealers, and wood finishes. The company, based in Asheville, is called Earthpaint. It’s founder, Tom Rioux, started his career in painting at the age of 14. After many years as a professional painter, Tom become deathly ill. His kidneys, liver, and lungs were failing and he had horrible arthritis. After 3 years of chemotherapy and major diet and other lifestyle changes, Tom pulled through. He was convinced that it was paint that almost killed him, so he decided to dedicate himself to researching and developing better paints.

After literally more than 1,000 failures and a major investment in lab time and other entrepreneurial necessities, Tom has developed a line of finishes that are truly amazing. They are biodegradable; made up of non-toxic, native ingredients from plants, minerals and other basic elements. Except for a single ingredient in one product, all of Earthpaint’s materials are harvested within an eight hour drive of Asheville. Most travel less than four hours. What’s more, they not only compare to modern synthetic finishes in price, but in many cases outperform them. For example, Earthpaint’s Interior Clear Skies wall paint carries a full 25 year warranty!

Talking with Tom about paint is a true inspiration. Not only because he’s fun and really knows what he’s talking about but because, well…you’re talking to him. He’s not just a billboard, a label, or a trademark. He’s your neighbor telling you real-world, no BS stories about the reality of paint. (Ask him about VOC’s, for example, if you want to hear a real nail-biter with a surprise ending.) Tom’s business is family-owned (no pesky stockholders demanding his soul) and truly local which allows his intentions to be personal and passionate. It also makes him accountable to us.  If we have a problem, we can talk to him about it. Such a set-up will by definition be “green” to the max. The rationale won’t be based on barely meeting provisions in compromised government regulations vetted by corporate interests, but on the simple and obvious credo that you don’t soil your nest.

To me, that’s the transformative power of building a truly local economy. Earthpaint’s success is our success. If Tom fails, we all loose. Perhaps our only problem is that we don’t really believe that we’re all in this together. As long as there is a mythical Bahamas to retire to, then people will continue to soil their bed before they sell it to someone else. What we need is more Earthpaints. They are out there trying to be born. All they need is our help. It’s a no-brainer, people. Buy, sell, eat, drink, build, live, and die local…unless you want some two-headed ten-eyed aliens coming down here to steal plastic from our cold dead hands.

For more information about Earthpaints, visit their website www.earthpaint.net) or call them at 828-258-2580.
