Most of us live in buildings made out of wood, concrete, steel or bricks. But some people are making their homes with bales of straw.


One couple in Grass Lake, Michigan, has spent the past two and a half years building a very energy-efficient home with straw bales. And it’s not just some little novelty project. Joe and Shelly Trumpey live in it, with their two daughters.


If you’re thinking Big Bad Wolf… Joe’s heard that one just a few times.


“That’s the most common joke, three little pigs, exactly.”

A blog about the Trumpeys from Joe’s alma mater

Transcript

But the fairy tale jokes stop the minute you turn the corner on the country road… and see the Trumpey home. It’s big… two stories, and more than 2,000 square feet. The outside is red adobe and it has a green steel roof. The whole thing is supported by a traditional timber frame and field stones.


Joe says they wanted to build with natural materials that they could get locally. They’re almost entirely solar-powered. And they wanted to live in a really energy-efficient house. Straw can do that.


“It’s cheap and the size of the bale gives you a lot of insulation.”


(door jingling as it’s opened)


Inside, it’s cozy even though it’s 20 degrees out with a biting wind. Joe says that’s because the walls are so thick. They have an insulation value two to three times greater than a conventional home.


And yes, they have electricity, running water, indoor plumbing. There’s even a flat screen TV hanging on the wall. Everything looks so conventional, you’d never know the walls are filled with straw.


“Here I’ll show ya. All straw bale buildings have a truth window – here’s a little doorway (sound of opening door) that we can open up that’s not plastered by the adobe so you can actually see the straw behind and show you the truth.”


And there they are: stacked bales of wheat straw tied with a red rope. The seed’s been removed so critters won’t eat it. But there are bigger worries.


“When you’re building the building all the open straw is a huge fire hazard at that point so we were really careful not to have any smokers around and no open fires. Once it’s coated with mud the fire proofing is really in place.”


Joe says you also have to let the straw breathe so it won’t trap moisture. Otherwise the walls could rot. He says the adobe plaster on the outside of the straw allows air to flow.


Before they could even start building, they had to win over their building inspector. Straw bale buildings are not in Michigan building code.


Tom Nolte ended up being Joe’s guy. He says inspecting a straw home was a first for him.


“Joe had his idea laid out for me and I simply left him with if you can get me the engineering details to chronicle how the roof would be supported and how it all ties together, I’d say let’s go for it! (chuckles)”


Nolte says Joe did that, and he’s satisfied the house is perfectly sound.


But building your house in an unusual way is not easy. Shelly’s a 3rd grade teacher, and Joe’s a professor. Before and after their day jobs… they worked on their house. They dug 50 tons of field stones out of their farm field. Joe milled every piece of wood himself. Shelly built the 35-foot high stone fireplace.


“My advice is don’t tell your wife how much work it’s gonna be before you get started because she’ll never go along with it! (laughs) The girls too. None of us had any idea how much work it was gonna be. (pause) To Joe: You did? Joe: It was more than I planned, but still, I knew (laughs).”


Joe and Shelly went through all this because they wanted to prove it’s possible to have a comfortable home with a small impact. One that uses natural materials from within miles of their home.


“I think it’s a great example for my students and for my children, in terms of being respectful to nature and living in this earth.”

Coal Power Plants Go Up in Smoke

Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

Many of the plans to build new coal-burning power plants have gone up in smoke. In early 2007, the Department of Energy noted there were 151 coal-fired electric generators on the drawing board. Lester Graham reports since then… nearly a hundred of them have been canceled—or shelved.

There are several reasons. The recession has tightened credit for building coal-fired power plants. Electricity demand has flattened- partly due to the economy—partly to better efficiency in businesses and homes. Lawsuits blocked some of the coal-burning plants. And some states are requiring power companies to compare the costs of burning fossil fuels to using alternatives such as wind because of concerns about climate change.

Ted Nace is with the environmental advocacy group CoalSwarm. He says he thinks this slow down in building coal-burning power plants is permanent…

“It’s a pretty profound shift in the American economy. And a lot of it’s being driven by economics, but also a lot of it’s still being driven by climate concerns.”

Some new coal-burning power plants did go online last year… but in real terms there was just as much new wind power installed.

Radon Continues to Plague Americans

  • David Aschenbrenner from Pro-Tech Environmental installs a radon mitigation system. (Photo by Mark Brush)

There’s an invisible, odorless gas that kills 21,000 Americans every year. We’ve known about radon gas for a long time. But as Mark Brush reports, experts say we’re still a long way from fixing the problem:

Transcript

There’s an invisible, odorless gas that kills 21,000 Americans every year. We’ve known about radon gas for a long time. But as Mark Brush reports, experts say we’re still a long way from fixing the problem:

Radon gas is found down here…

…in the basement.

Really, it’s all around us. The gas drifts out of the ground from bits of uranium ore. Normally, there’s not enough of it to cause a problem. But it can get trapped in our homes, schools, and offices. We breathe it in. And the gas can cause lung cancer. It’s the second leading cause of lung cancer next to smoking. And if you’re a smoker – you’re even more at risk.

The level of radon gas in this basement is unsafe. More than four times a safe standard set by the EPA:

So a crew of two guys is here to fix the problem.

David Aschenbrenner works for Pro-Tech Environmental in Ann Arbor, MI. He says radon gas seeps up from the ground and makes its way into the house through cracks and holes in the foundation:

“So as the air is rising through the house, the house acts as a chimney. It’s creating what we call the stack effect. And that’s what’s actually pulling the radon in.”

You can’t see it. You can’t smell it. But it’s often there.

“So with the radon piping, and the radon fan, it’s going to create a suction slightly stronger than the house breathing normally.”

They drill a hole in the basement floor – put a PVC pipe into the hole. And fan on the pipe will vent the radon gas outside.
Right now – a lot of people find out about radon when they buy or sell a house. The air is tested and if there’s a problem – it can be fixed.

Bill Field is an epidemiologist at the University of Iowa. He’s studied the health risks of exposure to radiation for decades. Field says these systems work. But even though more people know about the threat of radon gas – there are still more people exposed today than in the past:

“We’re further behind now, than we were 20 years ago with addressing the radon issue, because more homes are being built that aren’t radon resistant than are being mitigated. Each year there are tens of thousands of home that are coming on the market that will hopefully be fixed someday, but they could have been fixed when they were first built.”

Field says new homes should be built to keep radon out. He says simple changes in home construction – changes that would only add $500 in construction costs – would work. He says there should be a federal requirement to build homes this way, since radon can be a problem in every state.

There are some states, counties and cities that have radon resistant new construction written into their building codes – but more than half don’t – and even in the places that do have the code on the books – workers told us that it’s not always enforced – so it’s easy to just skip the requirement.

The National Association of Home Builders says it would oppose any federal requirements to build homes this way. They say radon should be dealt with where there are known hot spots.

There are parts of the country where radon can be bigger problem than in other areas. But it can be a problem no matter where you are. The EPA has a recommended standard for radon gas. It says that homes or offices or schools should be fixed if they have radon levels of 4 pico-curies per liter or more. But Bill Field says sixty percent of the cancers caused by radon were caused at levels below this EPA standard:

“Talk about a safe level of four pico-curies per liter is really a misnomer. It’s like saying it’s o.k. to cross the road blindfolded because there’s only one car coming instead of three. There really is no safe level of radon.”

A recent report by the President’s Cancer Panel evaluated the progress being made on cancer prevention. Exposure to radioactive radon gas is one of the areas where the experts said not enough is being done. And because the problem is getting worse – they’re recommending the government do more.

“You can test your air for radon gas by buying a test kit at your local hardware store. They cost between ten and twenty dollars.”

New Homes for Chimney Swifts

There’s one American bird that has an unusual habitat problem. Chimney Swifts have adapted in the past as humans encroached on their territory. But now changes in human behavior are presenting new problems for the birds. And some people are trying to help them adapt again. Stephanie Hemphill reports.

There’s one American bird that has an unusual habitat problem. Chimney Swifts have adapted in the past as humans encroached on their territory. But now changes in human behavior are presenting new problems for the birds. And some people are trying to help them adapt again. Stephanie Hemphill reports.

In his dad’s window-and-door warehouse in the Minneapolis suburbs, Derek Meyer is supervising the boys in his scout troop as they build a wooden tower for Chimney Swifts.

They’re using rough plywood to build a narrow box twelve feet high with an opening about a foot square.

Derek is doing this project to earn the rank of Eagle Scout. In the process, he’s learned a few things about the lives of Chimney Swifts.

“They originally lived in hollow trees but when the settlers from Europe came over they started destroying the trees, so they decided to live in the chimneys, and then people started putting wire over their chimneys, so over the last 40 years they’ve lost half of their population.”

Not just wire, but rain caps and other devices to keep moisture and critters out of chimneys.

The new home these boys are building for Chimney Swifts is destined for the nature center next to a nearby school. The school district was planning to tear down an old brick chimney as part of a remodeling project. Rebecca Field found out about that, and she tried to stop it.

“I said, wait a minute, I’m sure there are Chimney Swifts in there and they’re really good birds because they eat about 2,000 insects a day, each of those birds. And their favorite insect is the mosquito.'”

Field is on the board of Audubon Minnesota, and she’d been watching the swifts hanging around the chimney in the evenings. Individually they look like fat cigars with wings, but when they get ready to swoop down into the chimney for the night, there are so many of them, they look like a funnel cloud.

“How they communicate I have no idea, how they put the brakes on when they dive into that chimney so quickly, it’s a mystery but it’s a fun thing to watch.”

In the end the school district decided to leave the chimney up.

So now, a few weeks later, and just in time for the Chimney Swifts to fly back up from the Amazon, the tower is standing on a concrete pad at the school’s nature center.

School naturalist Marleane Callaghan has already brought all her classes, grades three-through-five, to check it out.

“We’ve talked about the bird, what it looks like, the dimension of it, I’ve invited them to come back with their parents to watch in the school parking lot in the evening up at the high school where they’ve left the chimney, and then to walk on down, to be able to identify them.”

This project is part of an effort by Audubon groups all over the country to raise awareness of Chimney Swifts and their need for homes.

In Minnesota, project director Ron Windingstad wants to convince homeowners to make existing chimneys more welcoming. He says people can take the caps off their chimneys during the summer, or just raise them high enough so the birds can fly in from the sides.

Soon these school kids will be able to see the amazing acrobatics of the Chimney Swifts. Windingstad says they hardly ever stop flying, from morning til night. They’ll even sip water and take a bath in a nearby pond, without stopping.

“They’ll scoop down, lower their bill, and fly across it and drink in the water. They’ll use some of these shrubs around here to break off little twigs about the size of a wooden matchstick or toothpick actually, and use that to build their nests, and they do that while flying as well. They are marvelous creatures.”

Rainwater Toilets Caught in Red Tape

Sometimes we hear complaints that environmental regulations stop us from doing what we want with our property.
Environmentalists say there’s one issue where doing the green thing can attract a bunch of red tape.

Shawn Allee reports it’s about using rain water to flush our toilets.

This story starts at a forest preserve in Lake County, Illinois, north of Chicago.

Jill Stites is here to show off the forest preserve’s custom-built welcome center.

Stites: This building was built for people to come out and see what people could do in their own homes.

In other words, the idea was, we could do it, it didn’t break the bank entirely, here’s something you might want to try, that sort of thing?
Stites: yes, you can really do green building in a responsible way.

Stites shows me how the building collects rain water from the roof.
That keeps rain out of sewers.
That way, the local waste-water treatment plant doesn’t waste chemicals and electricity to purify rainwater.
After all, rainwater’s already clean and you can store it in cisterns, like this one.

Stites: It collects water off of the roof and goes directly in there. and there’s a spout on the bottom of the cistern that you can hook up a hose to and water your flowers with.

But Stites’ building wanted bigger bragging rights.
They wanted to prove people can collect rain water for more than just flowers.
You can use it for something more urgent: flushing your toilet.

Stites: you don’t need drinking water to flush your toilet. you’re saving the water from going to the storm sewers to be treated to come back as drinking water when that’s not necessary.

There was trouble, though.
The forest preserve district couldn’t get a permit to use rain water in the toilets.

It wanted a connection to city water, as a kind of backup.

But the state worried untreated rain water might somehow contaminate the city’s drinking water.

It took years to get special permission.

Stites: We’re bragging about it. It’s been in the paper about the possibility of it happening and we’re hoping by summer that it’s going to be a fact.

Well, the Lake County Forest Preserve District got its permit, but it won’t let the issue die.
It wants average homeowners to have an easier time, so do environmental groups.

Ellis: It’s a time-consuming process. If we’re going to have more individuals and business doing this, it’s just going to become a bureacratice mess if they have to get variances every time.

This is Josh Ellis.
He’s with the Metropolitan Planning Council in Chicago.
He wants rain collection for toilets to go mainstream in Illinois, but state law needs an update.

Ellis: It would just be a matter of course instead of a special process just to run your toilets a little bit differently.

He says engineers and plumbers have proven rain water collection can work for toilets, safely.

Ellis: We just need to upgrade the plumbing code and I think it will be smooth sailing from there.

Maybe smooth sailing … if you have the cash.
I ask an industry leader for specifics.
His name’s Joe Wheeler, and he’s with the American Rainwater Catchment Systems Association.
The U-S Environmental Protection Agency estimates, each year the average household spends just 200 dollars on water.
Wheeler says, for a rain water collection system …

Wheeler: You could do a really good job for about 4500 to 15,000 dollars. Every house is different. We’re not talking McDonald’s Big Macs here, we’re talking every one of them is a unique situation.

Wheeler says overseas, using rainwater for toilets is common and cheap.
Take Germany, for example.

Wheeler: Basically when you go into a home, you don’t know … you can’t tell the difference.

But Wheeler says German homes and businesses get pushed toward rain harvesting.

Wheeler: People would actually get a rebate on their waste water and that gave the whole market in Germany a critical mass.

It doesn’t work like that here, so in the U-S, rain harvesting for toilets is nowhere near critical mass.

Greenovation: The Great Floor Debate

The popular eco-friendly products are not always the best solution. Lester and Greenovation.tv’s Matt Grocoff drop in on Matt’s neighbor to help him with his hardwood floor dilemma.

Transcript

In home improvement projects, the popular eco-friendly products are not always the best solution. Lester Graham has the story of a home improvement intervention.

Kevin Leeser was not happy with the floors downstairs in his one-hundred year old house.

KL: “Well, we’ve lived here five years and just over the five years they’ve started to get grayer and you can tell that the finish was –in the high traffic areas—you could tell where we were walking it looks like we were hamsters walking through this place.”

LG: “This is maple, right”

KL: “Pfft. Yeah, that’s what they tell me.”

Kevin toyed with the idea of finishing the maple floors… but that sounded really involved.

And then the in-laws visited during the holidays.

KL: “My mother-in-law was like ‘Why don’t you get new floors.’ (laugh) And I was like well, yeah, it would be easier, ‘cause the things I was concerned about were sawdust, and ‘cause I have a newborn, just dirtying up the house and figured just getting some clean stuff, cutting it outside, sticking it down and be done with it.”

LG: So, wanting to be eco-friendly, he thought he’d put down bamboo flooring. Bamboo is renewable and it grows fast… and it’s pretty popular these days.

Then his neighbor stopped by. Matt Grocoff… the eco-friendly home improvement guy with Greenovation-dot-TV who had some –eh—thoughts about Kevin’s plan…

MG: “And, I, like, practically smacked him in the face and I said ‘What are you thinking? This is a gorgeous floor. Go rent yourself a sander or even hire someone for a few hundred bucks to strip the floor and then refinish it.’”

LG: So…You’re not a big fan of bamboo?

MG: “Bamboo is a great product if you have to do something new. You have to ask a question: do you need that new product or do you have something that works now and just needs to be renewed.”

Oh, yeah. Reduce. Re-use. Recycle. So, Kevin’s wife, Lauren and their baby were away for a few days. Kevin rented a sander… …and then started looking for an eco-friendly sealant for his maple floors. Matt had an idea for that.

MG: “Kevin’s using a natural oil from BioShield which is a mixture of tung and linseed oil that is so easy to use. It’s easier to use than even a low-VOC or zero-VOC polyurethene finish and easier to maintain in the long run.”

And in the end… renting the sander, buying sanding pads, buying the floor sealant, paint brushes and all that stuff… ended up costing Kevin about HALF of what it would have if he put down bamboo. Not a bad deal.

But… the big question… what did his wife, Lauren, think of the refinished old floors.

LM “It looks absolutely beautiful and we didn’t have to get new floors. Win, win. We love it. Beautiful.”

Matt Grocoff says he was sure Kevin and Lauren would be happy, because he did the same thing at his house.

MG: “The first thing that I did when we finished with our floor is I took a glass of red wine when we were celebrating and I poured half a glass of red wine on the floor and my wife was like ‘What are you doing!’ And I was like, look, we’re going to spill wine on it eventually, let’s see what happens now. The wine beaded up on the floor. We took a little sponge, wiped it clean and it’s gorgeous, five years later.

LG: “That’s Matt Grocoff with Greenovation-dot-TV. Thanks, Matt.”

MG: “Lester, this is always so much fun. I’m glad to be doing it.”

LG: “That’s The Environment Report. I’m Lester Graham.”

New Houses Get a Little Smaller

  • Huge houses are on the decline. (Photo courtesy of Brendel Signature)

The American dream of home ownership has become a trend of bigger and bigger houses. The square footage of new, detached houses crept upwards for decades even though families shrank. Recent economic troubles have stopped the big house trend. Shawn Allee reports:

Transcript

You might not know it but the American dream of home ownership has translated into bigger and bigger houses.

The square footage of new, detached houses crept upward for decades, even though families shrank.
Shawn Allee reports recent economic troubles have stopped the big-house trend.

Housing stats kinda say it all.

Just after World War II, brand new single-family detached homes were about 1100 square feet.
By 2007, they were twice as big.
One builder, Andrew Konovodoff, says 2007 was the peak.

Konovodoff: My analogy is, you go to McDonalds, you can up-charge or supersize your meal and get a couple hundred extra french fries.

Alee: People did that with homes?

Konovodoff: Yeah. Money was available. People bought more home than they needed. Now, I think people have trended back the other way.

Konovodoff’s right.
The U-S Census bureau says brand-new homes shrank for two years straight, and home builders say they’re going to build smaller for at least another year.

That hasn’t happened in decades, and builders like Konovodoff are adjusting

In the smaller square footages you won’t see a formal dining room … you’ll have an eat-in kitchen. We’ve pushed out the formal dining room.

Konovodoff says he’s considering even smaller designs.
He says it’ll be trickier to make a good living, so he’s not exactly happy with the trend.
But there are people who are glad houses are getting smaller.

One of them’s Alex Wilson.
He edits a magazine called Environmental Building News.

Wilson: In building a house, we need lumber, new windows and a whole range of building materials. It’s just common sense that a smaller house will use less materials. Even with any material, a so-called green material made from recycled content, there’re still impacts from manufacturing that product and shipping it to the job site. So, when we use less, we reduce environmental impact.

Wilson says the size of new homes has dropped just a bit … maybe the equivalent of a big closet or a tiny, tiny dining room.

He’d like homes to see homes get even smaller, but that won’t happen until our heating and cooling bills jump higher.

Wilson: I think if we were paying five dollars a gallon for gasoline and equivalent prices for natural gas and heating oil, then we would see a much more dramatic drop in house size.

Wilson says most of us won’t demand or build small houses until we truly fear a life-time of high utility bills.

n many older cities, some
neighborhoods are known for
their abandoned houses. A
lot of these will decay beyond
repair and end up as debris
in landfills. Emma Jacobs
takes us to one hard-hit
neighborhood, where one house
has become a laboratory for
doing green construction:

(sound of climbing steps)

Last year, at age 20, Megan McNally bought a house.

”This is the front room. Um, this is gonna be the bathroom. Doesn’t look like much now. It’ll get there.”


Not just any house. She wanted to find a project in this neighborhood to tie to the environmental science she studied during the year.


While home from college for a summer, McNally had been working with a nonprofit, Buffalo Reuse. It works in a neighborhood of East Buffalo with rows of abandoned homes. She paid $3800 dollars at the city’s foreclosure auction for a small, wood-frame house that had been vacant for three years.

“I really wanted to help some effort in Buffalo and so I was trying to brainstorm and I sat down with Michael and we sort of came up with this idea of buying a house.”

(sound of truck)

Michael is–Michael Grainer, who runs Buffalo Reuse. We make a coffee run and he tells me this neighborhood is part of a city whose population has shrunk by half.

“What we’re trying to do is to build a base of projects that are undergoing some kind of transformation and also lots that are undergoing a transformation.”

McNally’s house looks like it’s in good shape, but it had also taken a lot of abuse.

“On the outside, it looks really great. You could move in tomorrow. But as I came in here the first weekend it was leaks that people didn’t take care of. There was…this floor we had to cut out because it was all rotted from black mold.”

McNally had no prior knowledge of home repair. Transforming this house soon escalated as she found she would be replacing the plumbing and heating. But in some way, she’s also found her lack of experience to be an asset in recruiting help.

Ken Hicks is helping to measure out a part for a radiator in the front room. He turned up near dusk one day last winter. McNally was under the house checking the foundation, and Hicks, a construction worker was helping out the owner next door. He saw her feet sticking out from underneath. When she crawled out they started talking.

“It was a big joke, you know. We went back and forth and I said, you know, it was just so weird to see you in that situation and that situation and that predicament. And we just started from there,”

Slow work during a down economy means Hicks spends more time on volunteer jobs. He’s become one of the main people McNally turns to with questions about plumbing and carpentry.

“Being really young, you can ask a lot of stupid questions, and people go, ‘Oh man, this girl,’ but then go on and like, answer it in a way where maybe they wouldn’t be so open with somebody else.”

“Anything you can possibly do wrong has been done has been done in this house. But all those things that I’m talking about are now corrected, and there’s so much more knowledge here.”

There’s still months of work left, but McNally knows she will be living here soon. She has learned both a lot of construction skills and a lot about teaching, herself. She holds workshops to help the neighbors who are left take on their own properties. Her house, still unfinished, is a good training ground for beginners. McNally also realized people are less afraid to approach her with their questions than the experts she first had teaching.

“It’s hard putting things together. And, I don’t know, there’s been times where you just want to sit down and you get so frustrated that you don’t know how to do something that I think it’s really important to have people there who say, whatever, it’s ok and it’s ok that you don’t know everything, because you know, once you figure it out or ask questions, or just do it (laughs) and hope that things work out for the best, they usually do.”

Chuck Quirmbach reports:

The company, Calstar, says it wants to open several U.S. plants which would use fly ash in making bricks for construction and paving. The California firm says its method uses far less energy that traditional clay bricks that have to be heated at high temperatures.

Luke Pustejovsky is a Calstar executive. He insists the quality of fly ash brick meets industry standards.

“We spent 18 months and millions of dollars on durability testing with our own labs, with outside third party labs, and this is a brick that’s built to last.”

But a trade group, the Brick Industry Association, is cool to fly ash brick. The group says the product has not yet met the test of time. The group is concerned any problems that come up could discourage customers from using brick.

Renovating old homes or apartments can
mean scraping or sanding lead paint.
That lead paint dust can settle where
children play. That can put them at risk
for learning disabilities. Shawn Allee reports why the government’s
tightening rules on home renovation:

The Environmental Protection Agency just finished rules about home renovation and lead paint, but children’s advocacy groups said they weren’t strong enough.

Anita Weinberg is with Lead-Safe Illinois. She says some rehab contractors are trained on how to handle lead paint safely, but only some property owners are required to hire them. Weinberg says the rules didn’t apply if there were no kids in that unit at the time.


“That’s perfectly fine, but tomorrow you turn around and sell your home to a family with children. And the work that was done, if it wasn’t done safely, there’s certainly the possibility there’s still going to be a lead hazards in that home.”

So, now the EPA’s proposing, if you hire a rehab contractor at all, that contractor must be trained to handle lead paint – regardless of whether children live there now or not.

The rules would apply to homes built before 1978.
