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.

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.

Big Perks for Tiny Houses?

New homes in America keep getting bigger and bigger. The average new
American home is about 2400 square feet. Moving up to a bigger house
can seem like a sign of success… or it might feel necessary for a
growing family. But in the face of pressure to buy big… some people
are choosing to downsize their homes… way, way down. Rebecca

New homes in America keep getting bigger and bigger. The average new
American home is about 2400 square feet. Moving up to a bigger house
can seem like a sign of success… or it might feel necessary for a
growing family. But in the face of pressure to buy big… some people
are choosing to downsize their homes… way, way down. Rebecca
Williams visits some of the tiniest houses on the block:


(Sound of door opening)


“C’mon in!”


Andru Bemis lives in a little house on a corner.


“Here it is, you’ve just about seen it. You’re standing looking at the
kitchen, you’re standing in the living room, there’s a study, and
there’s a bathroom behind that wall and somewhere above the bathroom there’s a
bed.”


It takes a hop, skip and a jump to cross from one end to the other.
That’s because his house is 300 square feet. Total.


Andru Bemis says a little house is better:


“I’m not owned by it, that’s one of the biggest things. I’ve only got
one sink I’ve gotta keep running, I’ve only got one of anything, don’t have an entire house to
take care of. I also leave town a lot and don’t have to leave an
entire house and worry about it.”


Bemis is a musician. His love of music explains the 5,000 records
lining one wall of his house and taking up precious space.


Of course he also makes room for his banjo.


(Sound of strumming)


You just don’t see tiny houses that much any more. Some, like Andru
Bemis’, are remnants from the early 20th century. His tiny house is in a sleepy
neighborhood that used to be the factory district. He’s seen other
little houses like his get torn down to build bigger new ones.


“Bigger is better, I guess. Bigger means you’ve achieved a lot more.
But as far as I’m concerned bigger generally means you’re working a
whole lot harder.”


That’s one reason people are choosing to live small. They’re after a
simpler life with less stuff. A smaller house costs less to buy and
maintain. And some people argue smaller homes make better use of
resources because they just use less of everything.


Jay Shafer says building small is the greenest thing you can do with a
new home. He owns the Tumbleweed Tiny House Company. He designs and
builds super small houses. He started with his own home. It was
really tiny – 70 square feet. That’s 7 feet by 10 feet.


“It’s a huge challenge – it’s much harder than designing a large house.
There’s just no room for error. And if you want to do it well and get
the proportioning right you have to consider everything as part of
everything else.”


Shafer says to live in a tiny house, you have to figure out how much
elbow room you need. Turns out, 70 square feet was a tad too small for
Jay Shafer. So he traded up to 100 square feet.


Shafer says tiny houses are a tough sell for most Americans. But some
people just love small little spaces. Shafer calls himself a
claustrophile. He’s built 10 tiny houses and sold dozens more plans.


Gregory Johnson is one of Shafer’s converts. He’s a computer
consultant in Iowa City. He lives in one of Jay Shafer’s high tech
tiny houses. It’s just 140 square feet. But with a little bit of
magic, one room turns into three.


(Sound of sliding panels)


“You can take what was an office and in about 20 seconds it converts into
a dining area with a sink off to our right because that’s the kitchen.”


Gregory Johnson says his tiny house has changed him. He says he had
his doubts at first, like the time he visited Jay Shafer at the construction
site:


“He showed this little hole I was supposed to crawl through, the
passageway to the upstairs to the loft and I thought I might have to
lose some weight to get up in there (laughs).”


Johnson says he started really scaling back. He realized if he had a
refrigerator, he’d just fill it up with ice cream and pizza. Things he
really didn’t need. So to save energy, he doesn’t have a fridge at
all. He started eating nuts and grains and fruit. By shrinking his
life down to match his house he lost 100 pounds.


Johnson says tiny spaces don’t work for everyone. But he says he has a
fulfilling life with a whole lot less stuff and space to put it in.


Many tiny house owners such as Andru Bemis want their miniature homes
to make a statement: size does matter.


(Andru Bemis song: “my house is a very small house it’s the littlest
house there is/it’s bigger than yours”)

Architecture Students Go Solar

Eighteen teams from around the world are competing this week in a solar home
competition in Washington, D.C. Each team competes to see who can build the
most aesthetic and livable solar home. The Great Lakes Radio Consortium’s
Jennifer Guerra reports:


Richard King is the director of the Solar Decathlon
Competition in the nation’s capital. We called him on his cell phone as he
was wandering around the National Mall checking out the different houses.
We asked him why he thought solar homes have a future in the housing market.


“You see gas prices are going up, natural gas prices are going up. We call
that volatility in the supply market. Solar energy doesn’t have that. Yes,
you have to buy a collector that you put on your house, but from then, on for the
next twenty years, you don’t have to worry about the price of energy going up
because the sunlight is free.”


Free and limitless, as King points out, and the houses being put up on
the mall try to show how they take advantage of that energy and still look
like something you’d want to live in. As King wandered around the solar
village, he stopped at the University of Michigan’s house.


“Michigan just got their end caps on, and now we finally see what it looks
like. We were all wondering what they had up their sleeve, so it’s pretty
neat.”


Before the University of Michigan team shipped their house to D.C., we
dropped by the School of Architecture. They were just putting the finishing
touches on their entry.


(Sound of talking)


That’s John Beeson, the project manager of the Michigan Solar House
project. It’s called Mi-So for short. They had to be creative to make sure
their entry was dependent on the sun for energy.


“This is a solar contest, so we are very limited in terms of what we can do for energy production. We can’t even convert kinetic energy, somebody bouncing on something, into electrical energy. We’re very limited.”


The house has to be totally off the grid, which means lots of large
batteries and thin, photovoltaic panels, neither of which make for an
aesthetically pleasing house. And in the world of architecture, if it doesn’t look good from the outside, no one’s going to care if its energy efficient.


“Most consumers today aren’t gonna buy something just because it’s sustainable.”


Lee Devore is the Michigan team’s operations manager.


“But if you have two apples, and they’re identical, and their cost is
roughly the same, if one is more sustainable than the other, it’s that extra
thing, but the thing they’re really concerned about is that it’s still a beautiful
thing to possess.”


Back on the National Mall in Washington, D.C., Solar Decathlon
Competition director Richard King says in this contest, beauty’s as
important as sustainability.


“In the 70’s, we just stuck solar collectors on the roofs in all kinds of
directions and one of the barriers are a lot of people didn’t like that up there on
their roof. So we’ve employed these schools of architecture to design very
beautiful-looking buildings with solar integrated in to actually
prove that solar energy works.”


So to make Michigan’s solar house stand out as the belle at the D.C.
National Mall, John Beeson says the team turned to Michgan’s most noted
industry, the automakers, for tips.


BEESON: “People like taking their cars and tricking them out, and the house is the same thing, you
just don’t know you’re doing it, every time you move into it. So why not make the architecture built that way, so that people can change it and affect it the way they want. So for us, there would just be panelized construction. We would just put these panels up, I’m done with this sink, this mirror combination. I’m gonna take it down and sell it on Ebay.”


GUERRA: “Are people ready for this?”


BEESON: “We hope. If not, it’ll be a good exploratory example of it on the
National Mall for people to go see.”


Even after a winning team’s been picked, the challenges aren’t over. It’s one thing to build a solar prototype for the competition, it’s another to
take that prototype and turn it into homebuilding that can be mass-produced
for less waste and lower costs. Once that happens, we might just see solar
homes popping up in new neighborhoods.

The Dark Side of Bright Lights

  • Most of us are using 125-year-old technology to light our homes. 95-percent of the energy used by a light bulb is heat. Only five-percent actually is used to produce light. (Photo courtesy of the National Museum of American History, gift of the Department of Engineering, Princeton University, 1961)

Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient… and the trend in home lighting is moving toward using more energy… not less. As part of the series, “Your Choice; Your Planet,” the Great Lakes Radio Consortium’s Lester Graham takes a look at light bulbs… and starts at the beginning:

Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient, and the trend in home lighting is moving toward using more energy, not less. The Great Lakes Radio Consortium’s Lester Graham takes a look at light bulbs and starts at the beginning:


We’re getting a behind the scenes look at a pretty significant historical artifact. Marc Gruether is pulling back a plastic tarpaulin that covers a row of file cabinets.


Gruether: “We are in one of the storage areas in the Henry Ford Museum. And drawer eleven has this light bulb in it which I will very carefully remove. It’s certainly one of the oldest Edison light bulbs that’s in existence. This is one of the lamps that was used in the December 1879 demonstration at Menlo Park.”


Graham: “Now, looking at it, I can see that it’s got that kind of bulbous shape, I can see the filament, I mean, I would recognize this easily as a light bulb.”


Gruether: ““Absolutely. It’s a recognizable light bulb. You’re exactly right. That all looks forward to the kind of lamp forms that became common and that we’d recognize today.”


And that’s not all that’s the same. Just like the first light bulbs, the incandescent bulbs most of us use in our homes today, waste energy. 95% of the energy used is expended in heat. Only five-percent actually makes light. That means everytime you switch on the light – if it’s an incadescent bulb – you’re wasting 95% of the electricity your paying for. In our homes, not much has changed in the last hundred years or so. But in commercial buildings, things have changed a lot.


Commercial builders and industrial architects learned a long time ago that energy efficiency is important. Most of the new office building and factories built today use passive sunlight and high-efficiency lighting that not only saves energy but uses the right spectrum of light to get the best output from their employees.


Moji Navvab teaches about light in architecture at the University of Michigan. He says you can learn a lot about good energy efficient light too. He says with the wide variety of fluorescent, LED, and spot lighting, you can get the right kind of light for whatever you’re doing and use a lot less electricity compared to a house lit only by traditional incandescent bulbs. It’s about using the right light for the right place. Navvab says, really, it’s pretty simple and you can get a lot of information about proper lighting on the Internet.


“If you really are focusing on healthy lighting or you want to save energy, if you go search on the web right away, you can get the information and then you can go to your local stores and they can match it for you.”


But at the local store, most of the time buyers are not very well-informed at all.


Beverly Slack is a salesperson at Kendall Lighting in Okemos, Michigan. She says unless they ask, she doesn’t push energy efficient lighting. And when she does mention fluorescent lighting, which uses about one-fourth the energy that incadescent bulbs use, customers grimace.


“Right. But, they don’t realize the difference in the fluorescent lamps, how they’ve changed, how the different colors have changed in the fluorescents. They’re still thinking of the old standard cool white so, people don’t want them because of that fact.”


Slack says what customers really want is dramatic lighting, and lots of it. They want trendy, recessed lights and track lights that often use extremely hot burning bulbs in a way that’s interesting, but not often very useful.


“They want decorative, decorative, decorative. I mean, it’s amazing. Because I can just see their light bills going sky high.”


Slack says the trend in home lighting in recent years has been just the opposite of commercial lighting. At home, people are using more light, more fixtures, and less energy efficient bulbs. With the trend in new houses being larger, requiring more lights, and homeowners wanting decorative lighting to show off their big new houses, conservation at home is often just being ignored.


It’s no longer about turning off the light when you leave the room, it’s about lighting up the showplace. And as long as the power bill is lower than the mortgage, it’ll probably stay that way.

Green Buildings Mean Retail Greenbacks

Green building experts have known how to make buildings more energy efficient for a long time, but the building industry is slow to change – especially in retail. The Great Lakes Radio Consortium’s Karen Kelly reports on one company that’s challenging the status quo:

Transcript

Green building experts have known how to make buildings more energy efficient for a long time, but the building industry is slow to change, especially in retail. The Great Lakes Radio Consortium’s Karen Kelly reports on one company that’s challenging the status quo:


At first glance, the Mountain Equipment Co-op looks like your
typical outdoor retailer. You’ve got the
rows of protein bars and the freeze dried camping
food. Forest green backpacks hang from the wall and candy-colored kayaks hang from the ceiling,
but what makes this Canadian company unique is what you can’t see. Almost everything, the displays, the floors, even the concrete, is
environmentally friendly.


Architect Linda Chapman designed the store, which is in Ottawa – Canada’s capital. She says part of her assignment was to reuse as much as she possibly could.


“A lot of the steel structure that you see, the steel beams and the steel joists here are all from the old building that was on site here. It actually saved us time because there was a real backlog and delay from ordering steel at the time we were building.”


Being environmentally responsible is part of Mountain Equipment Co-op’s mission. It’s a non-profit cooperative. It’s million and a half members pay a small fee and have a say in how the company is run. Mountain Equipment’s Mark VanKooy says their members want the company to reflect their own environmental values.


“They’re the ones really out there hiking, kayaking, canoeing, rock climbing, and it’s in their interest, I mean… most people realize the connection to environmental stewardship and the outdoors – that if you aren’t an environmental steward, you’re going to lose your wilderness and the outdoors and the places you like to do those things.”


That mission resonates with customers such as Trevor. He’s been a member of Mountain Equipment Co-op for almost 20 years.


“It shows me they’re forward looking, they’ve got a keen sense of awareness about the environment they’re in here… good corporate citizenry if you will. I’m very comfortable here.”


(sound of store)


Mountain Equipment Co-op has built eight stores – each greener than the last. When the Ottawa store was finished in 2000, it became the greenest retail building in Canada. In fact, there are too many features to mention. They seem to permeate every section of the building. It ranges from the wood floors salvaged from local barns to the high tech meters that control the intake of fresh air.


Mark VanKooy says it cost an extra 10 percent to construct the building, but they’ll get that back in energy savings over the next decade, and he says that’s a key point in trying to persuade others to follow their lead.


“Obviously, if it was twice as much to build the same building with the green building practices as it would be through standard construction practices, it wouldn’t be worth it, because even as a demonstration building, no one in their right mind is going to look at it and say oh, it’s a nice idea but its cost twice as much, yeah I’m going to do it.”


VanKooy gives lots of tours to architects and business people, but the building industry has been slow to adopt the idea. One of the biggest challenges is the way that buildings are typically constructed. Architects often come up with a plan without consulting the engineer or the construction manager, but in this case, they all sat down together from day one. They discussed each step in the process. The approach is called integrated design, and architect Linda Chapman says it ensured the environment was considered at every step along the way. She describes how the group chose materials to use in the walls.


“In terms of which one would have the highest recycled content, which one would have the best price, which one would be easiest to build…so that’s how decisions were made as a group.”


(sound in store)


The Mountain Equipment Co-op did receive a grant from the Canadian government, but funding for this kind of project has mostly dried up. Still, proponents say interest in green buildings is growing. According to the US Green Building Council, 5% of new commercial buildings last year met its strict environmental standards.


Retail stores such as Starbucks, Williams-Sonoma and the Gap have already built, or plan to build, green stores. In Canada, the Mountain Equipment Co-op has added two more, that are even more energy efficient, and were built without government help. They say if a nonprofit outdoor retailer can do it, a lot of other companies can as well.

Preserving Downtown Buildings Helps Stop Sprawl

As people move to homes and businesses in the suburbs they often abandon beautiful buildings. Some inner cities are now filled with boarded up store fronts and dilapidated high-rises. A group of architects hopes that people will be less likely to do this if they value good architecture and design. The Great Lakes Radio Consortium’s Tamar Charney has this story:

As people move to homes and businesses in the suburbs they often abandon beautiful buildings. Some inner cities are now filled with boarded up store fronts and dilapidated high-rises. A group of architects hopes that people will be less likely to do this if they value good architecture and design. The Great Lakes Radio Consortium’s Tamar Charney reports:


Flint, Michigan could be the poster child for a city left behind. Parts of the city have crumbled since Flint’s
auto industry moved away. But like
many older cities, there are dozens
of architectural gems here… (sound up)
like the Mott Building. It’s the city’s
tallest building and the exterior, the
interior, and every detail right down
to the doors on the elevators (sound
of elevator) are designed and
decorated in the Art Deco style.
Albert Ashley is a security contractor
at the Mott Building. He says a week
doesn’t go by without someone
asking about it.


(elevator bings and boings)


“It’s quite regular, quite regular we
get comments about it and the
architectural design and so forth…
well they can tell that it was pretty
old building and well kept, you know,
and the design is pretty much the
same throughout the building, so they
notice that and they like it.”


(Sounds of traffic)


One person who has always liked this
building is Ron Campbell. As a child,
he’d stand here on the corner of
Saginaw Street waiting for the bus.


“I can remember asking my mother,
‘how many stories is that?’ And I
probably pestered her with questions
to the point where she was ‘just be
quiet and wait for the bus.’ But…
‘How high is that compared with the
Empire State Building? How many
buildings do we have like that?'”


With that kind of early interest in
buildings, it’s no surprise Ron
Campbell grew up to become an
architect. And he’s now written a
guide to the architecture in Flint.
It’s a pamphlet with pictures and
blurbs about 34 places in the city.
It’s available at highway rest stops
and at businesses and museums.
Campbell says he’s trying to
teach people about the various styles
of architecture found in the city, but
he’s also hoping the guide can in
some small way combat urban sprawl
by celebrating places that are
beautiful, well thought out, and
designed to last. He thinks that if
more people paid attention to good
architecture in many older cities
they’d be less likely to abandoned
them in favor of new buildings and
developments.


“The Guide is to show, you know,
‘here’s what
can come from good design. It
doesn’t matter if it was built in
1800’s or today. If it’s good design
and it interfaces well, it functions well,
it’s going to be with us, and therefore
we should use it and not think of it
as disposable.”


The Guide to Flint Architecture is one
of many projects local chapters of the
American Institute of Architects are
doing to raise awareness about
architecture and the environments
that we build. Similar guides have
been created for cities ranging from
Duluth, Minnesota to Manhattan.


Celeste Novak is the president of
AIA Michigan. She says the buildings
in a city can tell stories about the
community’s past.


“They are a museum that we are all
participants in, and so it’s important
that people understand that
about the buildings and the communities,
and so that they begin to treasure their
communities and that’s one way we
can all have more livable
communities and really prevent things
like sprawl and the unpleasant places
we all find ourselves at when we’re grocery shopping.”


Those strip malls and big box stores
near the highway look very different
from the places shown in Ron
Campbell’s guide.


(sound of footsteps on bridge)


Campbell and I walk across a small
wooden footbridge in the heart of
downtown Flint. We’ve just left a
peaceful riverfront park designed by
a well known architect. On the other
side of the river where we’re going
sits Carriagetown. It’s where the
vehicle industry began in Flint.


“Oh, Carriage Town is rich in history –
this is the birthplace of General Motors
Company with the Durant Dort
Carriage factory.”


After years of neglect, this factory
from the late 1800’s has been
restored as have many homes in this
historic district. Ron Campbell says
he’s glad Carriage Town was never
torn down. It’s part of the city’s
industrial history. And Carriage Town,
like the Art Deco Mott Building and
many other places in the Guide to
Flint Architecture are nostalgic places
for Ron Campbell. They’re reminders
of his past and things he’s done over
the years.


“Those buildings, it re-kindles
childhood memories for me, but then
I look at the future, and what are we
leaving for our children and our
children’s children and hopefully it’s
something just as memorable.”


He says design decisions can
change a community for better or for
worse. He and other architects like
him want to encourage people to
think about the buildings they have
and to pay more attention to
aesthetics. The hope is society can
do a better job protecting historical
structures, preserving natural
resources, and by doing so
controlling sprawl.

Bigger Homes, Better Living?

  • American houses are getting bigger and bigger, but some architects question whether more square footage leads to a happier life. Photo by Lester Graham.

Although family size is growing smaller in the U.S., house sizes are growing larger. The square footage of a home built in the 1950’s seems tiny compared to the houses typically built in the suburbs today. The Great Lakes Radio Consortium’s Lester Graham looks at the trend of ever-larger houses:

Although family size is growing smaller in the U.S., house sizes are growing larger. The square
footage of a home built in the 1950’s seems tiny compared to the houses typically built in the
suburbs today. The Great Lakes Radio Consortium’s Lester Graham looks at the trend of ever-
larger houses:


There’s no one answer as to why we’re building bigger houses. For some people, it’s a matter of
investing. Housing prices continue to rise and bigger houses sell well. People trade up. But…
for some homebuyers, it’s more than that. It’s a statement.


Lynn Egbert is the CEO of the Michigan Association of Home Builders.


“A lot of that could be a status symbol. Move out of the city; move into a rural-like area because
‘I’ve made it,’ because ‘This is my dream.’ It used to be people would move up, sell their homes
every seven to ten years. That’s changed now and the sale of homes is now three to five years.
You build up the equity in a new home or an existing home, you have the opportunity to build or
move into something else later. It is an investment.”


Investing in a house only explains some of the reason houses are getting larger. Another reason is
government. Local governments are zoning residential areas into large lot subdivisions. Egbert
says that means the builder has to build a big house, just to recoup the cost of the sizeable piece
of land.


“That is a preclusion, a prohibition against Smart Growth. When they have large lots sizes, it
absolutely dictates and mandates that anybody who moves in there is going to have a large
home.”


It’s an attempt by towns to keep out lower-income people who might build homes that lower the
property values of a neighborhood.


But there’s a demand for the bigger houses and it doesn’t seem to be letting up. So, cities and
towns zone for them, builders build them, and people buy them – bigger and bigger.


Linda Groat is a professor at the University of Michigan’s Taubman College of Architecture. She
says it’s not too surprising. People feel less connected to the community at large because they
move often, drive somewhere else to work, and see their home as a refuge. Home is where they
can relax and escape from the rest of the world.


“There may be, on the part of some people, a feeling of need to really make it more of a castle to
compensate for what feels more complicated or out of control in the larger world.”


We feel we need private places that we can call our own. But there might be social costs to that
refuge. There’s often little interaction with neighbors and the rest of the community in which we
live. And Groat says even within the home all that space means family members don’t have to
bump into each other on the way to the bathroom. Groat says in the new large suburban homes,
sometimes derisively called McMansions, everyone can pursue their own activities in different
parts of the house.


“If you buy a McMansion and the master bedroom is off on one wing and or a different floor and
the kids are off in huge rooms way on the other side of the house, is that really going to foster
family connection?”


Some architects are becoming aware the scale of housing is beginning to leave smaller
families with a sense of emptiness, not a sense of space. Sarah Susanka is one of the leaders of a
movement to re-evaluate the concept of whether bigger is really better. The first question is
“Why?” Why are we building bigger houses?


“Well, there’s obviously a large market for larger and larger homes. And my belief is that people
are trying to fill a void in their lives with the only tool that we’ve really defined for ourselves in
this culture which is: more. More stuff. More square footage. You know, more indication that
we’ve arrived. All that stuff.”


But Susanka says there’s a longing underneath all that, an idea that there should be some better
quality of life that’s not being satisfied by just more square footage. She’s the author of a series
of books that started with one entitled “The Not So Big House.” She argues that people can use
the money they’d spend on additional square footage for space that’s rarely used for better
designed spaces where they actually live day-to-day. She says if the house is an investment, then
it should be an investment in quality craftsmanship and better living, not just more space.


“When something is thrown together and just is sort of raw space, but not much else, over time
it’s going to degenerate. And, the amount of square footage obviously has a direct correlation
with the amount of resources it takes to build it. So by making something that’s tailored to fit – in
other words, not with excess material – and then that’s going to last a long time that that should be
the first step in sustainable design.”


Graham: “So, you suspect a lot of these McMansions or starter-castles, as you call them, aren’t going to be
around very long?”


“Yeah, I think in the long haul those are not going to survive in the same way and are probably
not going to be looked after in the same way over time just because they’re not as well put
together and they don’t have the charm that’s going to make somebody want to look after them in
the future.”


Susanka says using resources for bigger houses is not environmentally friendly and does not
necessarily mean better living. She says builders and homebuyers should think about it this way:
build the space you need and do it well and do it in a way that somebody in the future will want to
preserve.

A Canadian firm is gearing up to produce a cloth–like solar panel that will cost less than current
technologies. The Great Lakes Radio Consortium’s Lester Graham reports:


This is a photo-voltaic solar panel, but instead of being a sheet of silicon on glass, it’s tiny beads
of silicon between layers of aluminum foil and sealed in a plastic sheeting. It’s strong, light
weight, and flexible.


Ron Jutras is a company officer with Spheral Solar in Cambridge, Ontario:


“The primary difference between this particular solar panel and others that people are used to seeing
maybe on highway signs or potentially on buildings, is the fact that it is a pliable system, meaning
that it can be bent and wrapped around products.”


So the solar panels can be put on facades of buildings or draped over a roof. It also will come
in different colors, giving architects some flexibility. Because it uses much less silicon than
current technology, the price is expected to be quite a bit lower. The first commercial shipments of
the flexible solar panels are expected next year.

Building Demand for Green Construction

To the environmentalist, “green” refers to something environmentally friendly. When manufacturers refer to green, they usually mean money. But with an increase in the demand for environmentally sound buildings, manufacturers have the opportunity to combine the two definitions. For those who see the possibility, retooling to meet the demand for green construction could mean a large payoff in a burgeoning industry. The Great Lakes Radio Consortium’s Shula Neuman reports:

To the environmentalist, “green” refers to something environmentally friendly. When
manufacturers refer to green, they usually mean money. But with an increase in the demand for
environmentally sound buildings, manufacturers have the opportunity to combine the two
definitions. For those who see the possibility, retooling to meet the demand for green
construction could mean a large payoff in a burgeoning industry. The Great Lakes Radio
Consortium’s Shula Neuman filed this report:


There’s an 86-year old abandoned building in a Cleveland neighborhood that was left for dead a
few decades ago. It’s a shame because inside the building are 26-foot high ceilings with ornate
molding, original Tennessee marble walls and wood trim. But recently, the building, which was
once the Cleveland Trust Bank, was identified by a coalition of local environmental groups as the
ideal spot for their offices. The Cleveland Green Building Coalition spearheaded the task of
converting the old bank building into the new Environmental Center. Executive director Sadhu
Johnston explains, the project is not your average renovation.


“What we’re really trying to do is to demonstrate to people that you can do green while
preserving and that’s often they are seen to butt heads and this project is showing that the two
movements have a lot in common.”


While touring the mostly finished building, Johnston points out seemingly endless
environmentally friendly features. First, there’s a radiant floor heating and cooling system. Then
there are the geothermal wells under the parking lot. They use insulation made from recycled
paper and cardboard. And the roof is divided into three sections: one part has traditional black
tar, another has a white reflective coating and the third segment is a living roof, which looks like
a garden.


Johnston says the layout is meant to demonstrate a more than 100-degree temperature variation
between the three surfaces. All of the different materials and methods used to construct the
Environmental Center, could signal a forward thinking manufacturer to see financial reward from
the burgeoning interest in green buildings. After all, green buildings tend to save money.


The Environmental Center is 67-percent more energy efficient than required by code. In fiscal
terms, that adds up to a half-million dollar savings over 20 years. This might make you wonder
why more people aren’t building green. Actually, according to U.S. Green Building Council
president and CEO Christine Ervin, interest in green construction has been increasing over the
past decade. Since the group established green certification standards three years ago, nearly 700
projects have registered to meet certification. And, Ervin adds, the increase in interest is not
exclusive to tree-huggers


“The diversity of the kinds of projects also is telling us that this is a serious trend that is moving
into the mainstream market. We have projects that are registered firehouses, small schools, FAA
stations. All the way up to manufacturing plants and convention centers.”


Several cities and government agencies are already mandating green construction on new
buildings, including the city of Portland, the General Services Administration and the U.S. Army.


David Goldstein is with the Natural Resources Defense Council and environmental group in San
Francisco. He says there’s a movement afoot to establish national incentives to build green. In
other words, the time is ripe for the construction industry to get with the green program.


“From the point of view of the manufacturers of the equipment and supplies, and of the expert
building designers who put all these things together, once these policies for green buildings are
there, that’s a new market opportunity for them. So it is in their interest to promote these kinds of
policies.”


Goldstein adds green regulations also have a coincidental social benefit. With 35-percent of
pollution coming from the electricity and gas buildings use, requiring green buildings is as much
a public health issue as it is an economic one.


Some manufacturers in the great lakes region have caught on to the possibilities. The Cleveland
Based Garland Company manufactures and installs roofing systems all over the country and is
responsible for the Environmental Center’s roof—its first in-town green job. Garland
incorporates recycled materials into about 80 percent of its products. Nathan Schaus, project
manager at Garland, says about 15 percent of their business comes from their green product line.
Schaus says the market for green materials will continue to grow, especially with manufacturers
pushing its benefits.


“It’s a two-fold education. You need to educate the buyer, the end user that what they’re buying
is a building solution for the long term. So the initial investment, you have to explain that cost
over its life cycle. With the incentives, it’s changing the mindsets of the people that regulate
government and electricity today.”


Government regulators may work even faster on establishing incentives when they see the
increase in demand for residential green building on top of the commercial market. According to
the National Association of Homebuilders, about 13,000 green homes were built last year – a
huge increase over any single year before that. If demand continues to increase at such a rapid
pace, those business that go green now may be making plenty of green in the future.

Japanese Homes to Solve Housing Crisis?

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution. The structural pieces of a custom-designed home are cut out in a factory, using wood manufactured from small-diameter trees. Even unskilled workers can assemble the house on site in about a day.

The cost of building a home is soaring. Materials are expensive, and skilled labor is scarce. The high costs are contributing to a crisis in affordable housing, in the Great Lakes region and around the country. A new technology from Japan could be part of the solution. The structural pieces of a custom-designed home are cut out in a factory, using wood manufactured from small-diameter trees. Even unskilled workers can assemble the house on site in about a day. The Great Lakes Radio Consortium’s Stephanie Hemphill watched a home going up:


Five East 5th Street is a narrow lot a few blocks above downtown in Duluth, Minnesota. A new basement juts out of a hole in the hillside. From the front yard, there’s a spectacular view of Lake Superior.


Most of the houses in this neighborhood are at least 80 years old. They’re small houses built for working families. A few vacant lots show where dilapidated houses were torn down.


One day last month, the new house arrived on a truck.


(sound of Martin listing parts)


Santos Martin works for Kato Sangyo, the Japanese company that invented this system of homebuilding. He calls out the part numbers as half a dozen apprentice carpenters carry the pieces off the truck. Soon the lot is covered with stacks of house parts – corner posts sixteen feet long, and insulated wall panels in various sizes, as big as 4 feet by 9 feet.


Then the workers start to put the pieces together.


“Every component is numbered, every component has a specific place and an internal metal connector that allows you to put it together like you would a TV entertainment center or a bed frame.”


James Brew is the architect who had the dream for this house.


Brew was fascinated by Japanese culture since he was a kid. He’s traveled to Japan several times, and hosted exchange students in his home. Two years ago he learned about a Japanese company that created a home-building system that allows even inexperienced workers to frame up a custom-designed house in a day,


“People who haven’t built with this system, there they are pounding together a beam and a post and with a little bit of weather cooperation they will probably have this entire house framed today.”


The beams are made of laminated strand lumber. Instead of cutting big trees into 2 by 4s, laminated strand lumber uses smaller trees and even waste wood, glued together like plywood.


This type of “engineered wood” is being used more and more in homebuilding. What sets the Kato Sangyo system apart is the way the framing pieces are locked together with metal connectors.


The beams for this house are four inches square, and either eight or sixteen feet long. At the end of each beam there’s a slot for a metal connector. It’s like a large hinge. Workers slide one end of the hinge into the beam, and match the other end to a slot in the floor.


Then they raise the beam until it’s standing upright. They slide the insulated wall panels into the spaces between the beams. Everything is supposed to fit precisely because it was cut to order in a factory. Once the framing is up, workers will add siding, and the house will look just like the other ones on the block.


The assembly is mostly a matter of matching the right parts. So it’s an ideal project for people who are just learning how to build. Lisa Lyons is one of the crew members. She and her co-workers are part of a job training program for battered women. After a year of learning standard construction techniques, Lyons says this job is fun.


“Before it’s a lot of framing, a lot of measuring, and this here you just pound in some pegs and stand it up and it’s just like lego blocks, it’s really cool.”


The Japanese system offers not only speedy construction, but the potential for more affordable housing. The parts for this house were made at a factory in Minnesota. They were cut by hand, which took a couple of days. Architect James Brew says they could be cut in a couple of hours in a fully automated factory.


As the house takes shape, visitors stop by to watch. They include businesses thinking about the Japanese system as a possible new industry for Minnesota. James Brew says it would cost about a million dollars to buy the equipment to make the house parts. And he’s talked with a lot of lumber and construction firms that are intrigued with the idea.


“So there’s many interests in the system and the idea, the technology, but it’s again chicken and egg. Which is first, sales without a factory, or factory with no sales, or together. It’s very difficult.”


Brew is hoping the house in Duluth will provide the demo that will spur some business to decide there’s a future for the Japanese system in the United States. For the Great Lakes Radio Consortium, I’m Stephanie Hemphill in Duluth.
