The big bad wolf gave straw houses a pretty bad reputation. But it turns out straw bale houses are incredibly strong and energy efficient. The century-old building material is making a comeback as an eco-friendly choice for modern home construction. And these homeowners aren’t afraid of a little wind. One woman is even building a straw bale house in the sometimes cold, blustery climate of the east. Joyce Kryszak tells us her story:

This does kind of start out like a fairy tale. On the edge of the industrial city of Buffalo, New York there’s an ordinary little village. It’s dotted with aging, modest houses.

Carrie Zaenglein used to live here. That is until she lost her village home to fire two years ago. But that didn’t frighten the quiet-spoken young woman away. Zainglein says it just gave her a chance to rebuild. Only this time she’s building her dream home out of straw.

“I’ve always been interested in green building and doing things the environmentally friendly way, so I figured while I had a chance to start over I would do it the way I wanted to do it,” said Zainglein.

But how to go about it? You see, straw bale houses are growing more popular in the southwest. But you won’t find straw house builders listed in the yellow pages of most eastern cities.

So, Zainglein did a little searching on the web and found Dave Lanfear. Turns out, he’s building a company devoted to straw bale house construction. And Lanfear doesn’t care how much he’s teased about it.

“Yeah, I hear the same kind of jokes, I think, the three little pigs… and the same type of questions, but I just have to laugh. Yeah, I hear them,”

Lanfear just digs right in and gets to work plastering Carrie’s two-story contemporary style house.

Lanfear says to do it right you have to get dirty. He fills the wood frame with tightly packed straw bales. Next, the walls are coated inside and out with layers of clay plaster. It’s made with clay dug right from the site. Lanfear says it’s very organic and sustainable. But he says it also withstands the test of time.

“There are homes in Nebraska they didn’t even know that they were straw bale – they were actually hay bale. The walls got open, they were doing repairs and they discovered this hay in there and it actually looked fresh and they were a hundred years old.”

He says that’s because the plaster seals out the moisture but still allows the walls to breathe. That prevents mold and keeps the house sound. It also gets high marks for fire safety. And because the wheat straw is a just a bunch of hollow tubes it creates the air space that makes it a good insulator. Virtually everything about the house is eco-friendly.

The house also has solar heat and power. And it’s made mostly with reused materials. Even the trees cut down to make room for the house were brought inside and used for the framing. And Zaingline says rebuilding on her same small lot near the city means she’s not adding to urban sprawl. She likes to think straw bale houses could be a trend.

“The difference you can make, even though you’re only one person. I think it’s important for everyone to make these changes even if their small.”

Zaingline says her little straw bale house stands up just as well as any house made out of sticks or brick. It might just stand up to the bluster of critics too.

There are some ugly terms used
to describe big, grandiose homes.
Critics call them “Garage Mahals,”
“starter castles,” or “McMansions.”
These insults are flung around
in towns where people worry big
houses are sapping the character
out of neighborhoods full of smaller,
older homes. Shawn Allee
met a researcher who hopes to tamp
down the heated rhetoric:

Jack Nasar studies city planning at Ohio State University.

He got interested in the term “McMansion” because it was used in his own neighorhood in Columbus.

“A realestate agent was befriending older people so that when they died she’d be able to get their properties, tear down the house, and then build a much larger house. I started to wonder whether this was happening elsewhere.”

Nasar says teardowns, and the insults used to describe them, are common in many towns. And some local governments are restricting how big these homes get or even what they look like.

Nasar says, with governments stepping in to the debate, there’s more at stake than just name-calling.

“You’re talking about controlling what goes on on somebody’s private property. So, you would want to have good evidence to use as a basis for that decision.”

Nasar recently studied just what it takes for a house to get big enough or different enough for people to say, “yuck” or hurl an insult like “McMansion.” Nasar and a research partner created computer models of streets with rows of houses.

For each test, they made most houses normal, but changed up something about one of them – stuff like the architectural style, the height, or maybe distance between the house and the street. Then, they showed these models to people.

“We had them rate these streets in terms of compatibility, we had them rate them in terms of visual quality or preference.”

Differences in architectural style stuck out most, but after that, height.

“The effect started to be most noticeable when the in-fill house was twice as large as the stuff around it. So, in terms of regulations, it suggests maybe a community could get by saying, ‘you could do a tear-down replacement that’s twice as big as what’s around it,’ but you wouldn’t let it get any larger than that.”

This is a controversial finding.

Some communities keep height range much lower than “twice as big” figure and sometimes they restrict width, too – something Nasar found doesn’t matter so much.

I thought I’d bounce some of his findings off someone involved in the teardown issue.

“This also was a demolition of a small home.”

Catherine Czerniak drives me around Lake Forest, a Chicago suburb. She’s the community development director, and she gets the praise or blame about how teardowns get done.

Czerniak says Nasar’s findings make sense, especially the idea that style matters most.

“We often say height and size aren’t necessarily the key roles -it’s how the design is done.”

But for Czerniak, there’s a hot-button issue Nasar did not measure.

Lake Forest has lots of tree-lined streets and people like how the trees obscure the houses.

“And really, the landscaping really defines the character of the community. Even the estates on the east side, were not there to shout from the street, here I am, look at me.”

To make the point she drives past a mix of old homes and replacements.

I can hardly tell which is which.

“As we go down the street, take note that even though there are some big homes back here, you still feel you’re in a country lane.”

Czerniak says Nasar’s research might quiet down some debates but people will always fight over specific details. After all, Nasar’s test subjects gave quick judgements on computer models.

She says, in the real world, critics spend years nit-picking every little thing they hate about a teardown replacement home and whether it’s going to ruin their neighborhood.

The Future of McMansions (Part One)

Your home may be your castle,
but, for some people, too many
homes are as big and grand as
castles. Critics call these homes
‘McMansions,’ and they complain
they’ve ruined neighborhoods
filled with older, smaller houses.
The McMansion fad fizzled during
the real-estate bust. Shawn Allee looks at whether it could
return:

I head to a Chicago suburb called Hinsdale to understand the hub-ub about McMansions. Over the past twenty years, one in three Hinsdale homes got torn down to make room for mostly bigger ones.

Brian Hickey drives me past one-story brick and wood houses.

Then there’s a huge one, with stucco and Spanish tile.

Hickey: “This is an example of something where someone would go, this is more Florida-like.”

Allee: “It looks like it walked off the set of Miami Vice or something like that.”

Hickey: “Yeah.”

Bigger, mis-matched homes sprouted up in Hinsdale during the real-estate boom, and for some, Brian Hickey’s partly to blame.

He runs tear-downs dot com. Hickey finds and sells homes to tear down, and maybe replace with McMansions … or ‘replacement homes’ as he calls them.

Anyway, during the housing bubble, teardowns increased … and so did complaints.

Allee: “Some of the arguments I’ve heard against the teardown phenomenon is that we’re basically tossing perfectly good houses into landfills.”

Hickey: “See, that’s not accurate. To take some of these homes and bring it up to what people in this community would expect in terms of housing amenities, it doesn’t make sense to renovate when you can build new for less.”

The big-home trend faded recently, but if the soft real-estate market improves, you gotta wonder: will people build big again, or will they keep smaller, older homes?

Hickey thinks old homes might lose.

Hickey: “At some point a buyer simply won’t pay that price to live there.”

Allee: “In that one story …”

Hickey: “In that one story, two-bedroom, small kitchen – that the land will be where the value is.”

Some real-estate pros say Hickey’s right: people want big, and they’ll build what they want, where they want.

Others say, the game has changed.

Local governments in Dallas, Denver, and other cities are starting to regulate teardowns, like Hinsdale did.

(sound of a printer)

Robert McGinnis prints me 60 pages of Hinsdale’s zoning codes.

“Hot off the press, it’s still warm.”

McGinnis runs Hinsdale’s building commission. He says the code got up to sixty pages partly because of teardown complaints.

McGinnis: “Pollution issues, the loss of sunlight in some cases.”

Allee: “Loss of sunlight? What do you mean by that?”

McGinnis: “Some of these houses are so tall they end up physically blocking out some of the sunlight.”

McGinnis says it’s hard to stop teardowns – you can just delay or improve them.

“I would like to think, at some point, Joe Q. Public says, ‘I’d really like to live in Hinsdale, but I can’t afford to heat and cool a McMansion,’ so they’re going to look at building a smaller home.”

But McGinnis says this could be wishful thinking.

So, I thought I’d ask some Hinsdale homeowners about the small-home idea.

Just outside McGinnis’ office, I find Greta Filmanaviciute. She’s stuffing official demolition signs into her car.

Filmanaviciute: “I was getting permits. We’re going to tear down old house and building the new house.”

Allee: “Are you guys looking at a house that’s bigger than what you have now?”

Filmanaviciute: “No, actually, we are sizing down, but that’s because we’re a three-person family and I don’t want to have a huge house and then we have high utility bills. This is perfection for us, actually.”

Filmanaviciute says preservationists might not like that she’s tearing down her place, but her neighbors are glad she’s keeping things modest.

She says she’d be proud to start a small-home trend.

This week, the US Department

construction for single-family
homes increased 1.7% since June. Lester Graham
reports… what the announcement
didn’t say is that, on average,
those new homes are smaller:

For the past 35 years, houses have gotten bigger and bigger. The square footage has increased 53%.

But, starting in the second half of 2008, that changed. And the trend to smaller houses is continuing this year.

Steve Melman monitors trends for the National Association of Home Builders.

He says, during past recessions, new house sizes decreased because smaller was more affordable. As soon as the economy recovered, the trend toward larger homes continued.

He says that might not be the case this time.

“This could be a change in that the homes might incorporate better design, better energy features, green features, but not necessarily increase in size.”

A national survey of home builders found 59% are already building smaller homes or planning to build smaller homes in the near future.

This session of Congress has pledged to take on
the issue of climate change. A bill in the Senate
is already awaiting action. But the House has
already passed the sweeping Clean Energy And
Security Act. One piece of that bill could change
the way homes are built in this country. In short,
they’d use a lot less energy. Tamara Keith has more:

The bill would require a re-write of building codes. New homes would immediately have to be 30% more energy efficient. And the requirements would keep getting tougher from there.

The idea is controversial. But for Alex Dean, building efficiently is just the way he does business.

“It’s building to a higher standard. And we really enjoy building fine projects for people who want it done right.”

Dean is the CEO of the Alexander Group, a home design, build and renovation firm in Maryland. He’s showing me around a green remodel.

(sound of key in door)

“This is the entry from the garage into the new addition.”

Dean and his team are putting an addition on a home in an upscale Washington, DC suburb.

He’s designed every detail with an eye to energy efficiency, starting with the insulation. He used a spray foam. It costs about twice as much as the insulation required by current building codes.

“You know, it’s worth it, and in the overall scheme of building the house, it’s not that much money.”

On this hot humid day, you can feel the difference the fancy insulation makes.

Keith: “It’s cooler than it is outside.

Dean: “Yeah, yeah.”

Keith: “And there’s no AC running in here right now.”

Dean: “No, not at all. And this building is directly in the sun. But that’s how effective this is. This is keeping some of the coolness from last night when it was in the 60s.”

That means he can install smaller heating and air conditioning units that use less energy.

The windows are double paned. The lights, all compact fluorescents or super efficient LEDs.

It’s projects like this one that make Bill Fay confident home builders will be able to handle greener building codes. Fay is the executive director of the Building Energy Efficient Codes Network.

“We know it’s achievable. And we know it’s achievable using affordable technologies. It’s just now a matter to have the resolve to do it.”

Past efforts at greening the building codes met with stiff opposition from home builders and failed to make it through congress.

Koteri Callahan is president of the Alliance to Save Energy and she says the stakes are high. Buildings are huge energy wasters.

“Every house and every office building that goes in the ground today is going to be around for decades and decades and in some cases centuries.”

But these days, the ground isn’t being broken on very many homes. The industry is in a serious slump.

Bill Kilmer is the head of advocacy for the National Association of Home Builders and he doesn’t want members of congress to forget about the industry’s struggles.

“Consumers certainly in the last year are stepping back and said, ‘what can we afford.’ And so we’re trying to take a mainstream, if you will, that says, ‘people want this.’ How can we get to that point, and how can we get there reasonably, and take afford-ability into account.”

Kilmer says the building industry is taking environmental issues seriously, and recently created a voluntary green building certification program.

But, he says the House bill moves too far too fast. He says builders would like until 2012 to meet the 30% efficiency goal.

“You really don’t have the equipment or the materials that are ready and ramped up to make the adjustments in the marketplace to bring those things to bear, without a tremendous cost burden that’ll be added on to the production of the housing and that obviously is going to be passed on to someone, and that’ll be the consumer.”

This question of affordability is a big one. And it seems like everyone has a statistic to make their point.

Stimulus Money Spent in the Wrong Place?

You might have seen road construction signs that read, “Project funded by the American Recovery and Reinvestment Act.”

That’s economic stimulus money being spent on road repair and construction.

Shawn Allee reports one environmental group wishes there were less construction and more repair.

The land-use policy group Smart Growth America tracked how much stimulus money is going toward road repair versus road construction.

The group’s state policy director Will Schroeer says new roads and bridges are getting about a third of transportation stimulus dollars.

Schroeer says to employ the most people, we should be spending even more on repair, not construction.

“The largest reason for that is that you don’t have to buy any land to repair the road and as soon as you start buying land, that’s money that you can’t put toward wages and other things that produce secondary employment.”

Shroeer’ says about 20 percent of transportation stimulus money is still up for grabs.

That gives states about a year to turn spending toward projects his group advocates, including road and bridge repair and public transit.

Where to Put Solar Power Plants

Environmental groups have pushed for decades to get the federal government solidly behind solar energy. Shawn Allee reports some of them don’t like the government’s most recent effort to promote it:

The Federal Bureau of Land Management developed 24 “solar energy study areas” in Western states.

The idea is to identify federal land that might be be good for solar power plants.

Some environmentalists scoured maps of these solar study areas and got concerned.

Jeffrey Morgan is with Tahquitz Sierra Club in California.

Morgan says a solar plant can take up hundreds of acres, and construction could disturb desert tortoise and cactus habitat.

“They have no concept the desert is a vital, living place with a vast diversity of species, unspoiled landscapes and many, many other things. They they just see it as a waste-land. That’s just not true – it’s not a waste-land.”

The Bureau of Land Management says the “solar energy study areas” are just that – they’re for study – and the government would not let solar energy developers disturb critical wildlife habitat.

Portable Classrooms Get a Makeover

  • When schools run out of room, they often have to put students in portable buildings (Source: Motown31 at Wikimedia Commons)

When schools get too crowded, they often resort to sticking students in modular classrooms – cheap trailers, essentially. But Sheryl Rich-Kern reports some innovative architects are saying that the energy savings and efficiency of modulars make them an ideal, and often, permanent solution:

Transcript

When schools get too crowded, they often resort to sticking students in modular classrooms – cheap trailers, essentially. But Sheryl Rich-Kern reports some innovative architects are saying that the energy savings and efficiency of modulars make them an ideal, and often, permanent solution:

I’ve actually taught a class in one of those temporary, portable classrooms. It was in the early morning at a community college.

Students would walk in droopy-eyed. My job was to keep them engaged and awake.

Not an easy task – the room was either too hot or too cold. And the ventilation system made weird noises.

But, some experts say portables don’t have to be that way. They can be the kind of room that educators actually prefer.

Michelle Gould is a teacher and parent at the Carroll School in Lincoln, Massachusetts. And she teaches in a new kind of portable classroom.

“The air is very clean in here. It smells like the outside. It doesn’t smell like air conditioning or heating. The lighting is very good for not working under natural light. It seems like you’re outside. And it makes a big difference tutoring kids.”

Tutor: “Did you write your last name, Will? No? Very good, nice spacing. Close your books and put your pencil down.”

(sound of kids playing outdoors)

The Carroll School’s main building is a brick mansion from the early 1900s.

It is stately, elegant. The portable next to it is not. It’s boxy, and has a flat, white roof. Kind of ugly.

But, when you walk in to the portable you feel a change. It’s comfortable!

Cliff Cort is president of Triumph Modular, the firm that leases the country’s first green portable classroom.

“This is a vestibule, we think is a necessary ingredient to almost all buildings, because it controls the weather from the outside to the inside.”

Vestibules aren’t typically found in modular classrooms. Neither is the paperless drywall that eliminates mold, or the sensors that “learn” the best way to control the heating.

“If the teacher tends to come in early on Mondays, the building will begin to learn her habits, and then turn on the heating or A-C just before she gets here. And if they start to take off half a day on Wednesdays, the building would start to learn that no one is here in the afternoons, and then they can shut down. So it helps manage the use of the HVAC system.”

Cort points to the domed skylights known as sun tunnels, which bring in daylight.

“But they don’t bring it in a way that’s too harsh. As you can see, this is screened a bit. So it’s diffused light.”

Triumph Modular is just one of the companies making these more environmentally friendly modular classrooms.

Tom Hardiman is director of the Modular Building Institute, a trade association for dealers and manufacturers of commercial modular buildings.

“Improved acoustics. Improved daylighting. There are countless studies out there that show that it does improve the learning environment.”

Hardiman says many of the old-style portable classrooms end up being used for 20 or 30 years. The problem is they weren’t meant to.

But higher-end portables, like the one in Lincoln, Massachusetts, are built to last.

And, because of the modular construction, they’re greener.

“We typically produce much less construction waste material than site-built construction. Because our factories buy in bulk, they can resuse smaller pieces of material. If you’ve been on a construction site, you’ve seen dumpster after dumpster of two-by-fours and drywall and siding sticking out of the dumpster. There’s just not that much waste with modular construction.”

Hardiman says that green portables are the wave of the future.

They’re not the cheapest solution. But Hardiman says they do provide the best learning spaces on campus.

Growing a City in a Greener Way

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

Here at the grand opening of a subdivision in Trussville, Alabama, a few dozen families gather outside the sales office for the usual ribbon cutting with giant scissors.

(sound of applause and cheers)

Soon, everyone heads down to the Cahaba River. The river literally will be in the backyard of these houses once they’re built. On the river, they’re having a rubber duck race.

(announcement of duck race)

It’s gimmicky, but these days developers will do just about anything to attract potential buyers.

Another developer had approached Trussville about building homes along the Cahaba River, but then the housing market took a nose dive. The developer wanted out.

Trussville Mayor Gene Melton says the city would have been crazy not to buy the land.

“This property was probably going to sell for $35,000 or $40,000 an acre. We got to the point where we were able to acquire this for $4,500 an acre.”

The city could have turned it into an industrial park or zoned it for retail. But instead, they’ll turn it into a greenway. It’ll connect to nearby parks with the river as the centerpiece.

Now, the mayor of Trussville is not a staunch environmentalist, by any measure. He tools around the city in a gas guzzling SUV. He’s pro-development. But, he says, the same way a city needs development, it needs greenspace, too.

“Have you ever flown in to a big city like Atlanta or Los Angeles and for miles and miles all you see is rooftops? Well that’s how not to build a city.”

The Cahaba River watershed stretches through Alabama’s most populous county. Recently, heavy development along the Cahaba has polluted the water. It’s endangered habitats not just here, but downstream. Trussville is very near the headwaters, so what happens there affects the entire river.

Randall Haddock is thrilled about the new greenspace. He’ a field director with the Cahaba River Society, a conservation group. Haddock says the Cahaba River is among the most biologically diverse in the country.

“It turns out that Alabama has more fish species, more snails, more crayfish, more turtles, freshwater snails more than any other state in the US. So when it comes to things that live in rivers, we’re at the top of the list by a long way.”

(sound of people walking near river)

Haddock says all along the Cahaba, he’s seen plenty of examples of how not to build near the river.

He says this greenspace is an example of how easy it is to minimize impact. Keeping grass on the ground not only means a cleaner river, but it might help reduce flooding.

“When you make so many hard surfaces, the water runs off real fast and gets into the river real quick. And you’ve increased the volume of water and the only response that a river can make is to get bigger.”

The bank erodes, the water is polluted and soon, you start to see species diminish.

(sound of high school students)

David Dobbs is the city’s high school environmental science teacher. He takes his students out behind the school to check on the river. The result: a clean bill of health.

“All the little bugs, they end up being food for the fish, and the more they are of the good ones that are here, that means there’s more food for the fish, so therefore there’s more fish, it’s a very healthy part of the river.”

Trussville, like many small towns, still says without growth, there’d be no city. But now they know, that growth has to protect one of its top amenities – the river.

How Green Is the LEED Label?

  • LEED buildings get points for green things like bike racks and good energy use, but it doesn’t actually enforce energy efficiency (Photo by Lester Graham)

The biggest energy users in America are not cars and trucks – they’re buildings. Buildings use about 40% of the nation’s energy. In 2000, the US Green Building Council introduced a program that certifies “green” buildings. It’s called LEED. That stands for Leadership in Energy and Environmental Design. A new version of the LEED standards is being released today, April 27. But Samara Freemark reports some critics see serious flaws in the LEED program:

The biggest energy users in America are not cars and trucks – they’re buildings. Buildings use about 40% of the nation’s energy. In 2000, the US Green Building Council introduced a program that certifies “green” buildings. It’s called LEED. That stands for Leadership in Energy and Environmental Design. A new version of the LEED standards is being released today, April 27. But Samara Freemark reports some critics see serious flaws in the LEED program:

Before LEED came around in 2000, developers didn’t really spend a lot of time worrying about whether their buildings were green. They were designing and constructing buildings they could market. Green just wasn’t a priority.

“It was always the last thing on the agenda for the staff meeting, because nobody really understood what success looked like.”

Brendan Owens is a LEED spokesman. He says the people who came up with LEED wanted to change the culture of building in America. Make building ‘green’ marketable.

And they realized that to do that, they’d have to define what a green building looked like.

So they created a checklist. Install solar panels and you get points. Bike racks: more points. Get a green roof – somewhere you can grow plants — add some points.

Enough points and the developer gets a LEED certification. Certified buildings get a plaque. Developers get the PR boost that comes from building green. The public gets a more sustainable building. That’s the idea, anyway.

The program really caught on. More than 10,000 projects are currently going through the LEED process. And universities, municipalities, even the federal government are writing the standards into their own codes.

But critics say the system might be spreading too fast.

“The people who are writing the LEED Standards are in effect writing our country’s most important laws.”

That’s Henry Gifford. He’s a building engineer in NYC. He’s also one of LEED’s most outspoken critics.

Gifford says it’s possible to earn LEED certification – and cash in on the PR benefits of being green – without actually fixing a building’s biggest environmental problem.

“The 3 most important things to make a building environmentally friendly, are energy use, energy use, energy use. All the other things in the LEED checklist, which I think are wisely chosen and very important, they pale in comparison to the energy use.”

The LEED checklist does give points for good energy use- a lot of them, actually. But it doesn’t enforce energy efficiency.

Instead, developers win points by predicting their buildings will perform well. Developers do have to submit energy use data once their building is up and running. But if the building turns out not to save any energy? Brendan Owens says…

“What we do, is we notify the building that they’re not performing up to their potential.”

But no one’s coming around to unscrew that accreditation plaque. The building gets to keeps its certification.

On average LEED buildings seem to do better than others on energy use. But there are plenty of LEED-certified buildings that do use more energy than comparable non-certified ones.

Gifford says that’s unacceptable. No energy hogs, no matter how many bike racks or green roofs they have – should be allowed to call themselves green.

“It’s a scandal to have any underperforming building win or retain a rating for being green. I’m sorry. Every building labeled as green should have very good energy performance. Until we get there, we’re making believe.”

LEED doesn’t claim that certified buildings are perfect. Instead, Brendan Owens says the standard is meant to provide a holistic measure of greenness.

“I’ve heard LEED certified buildings described as sustainable. And there are a few, but the lions share of those projects haven’t achieved it. But that doesn’t necessarily mean that the rating system is flawed. It just means that people are misunderstanding what it’s about.”

In other words, people are reading more into certification than they should. Critics like Henry Gifford worry that will lead to complacency when it comes to truly greening buildings.
