We’ve been following Matt Grocoff with Greenovation.TV as he tries to make his home the oldest net-zero energy house in America. Last time we talked to him, instead of replacing his windows, he was refurbishing the 110-year-old wood framed windows. Lester Graham checked to see just how well that worked.

Repairing old windows

Transcript

The old windows in Matt’s house were drafty, but he didn’t like the idea of all the resources, energy and cost that replacing the windows meant. He got some help and took them apart, got them working right, painted them, and sealed the window panes the gaps. Today is the big test.

(blower sound)

Nick Helmoholdt with with the Clean Energy Coalition. He’s conducting a blower door test to see whether the Grocoff house is any tighter.

LG: “What kind of improvement did just refurbishing the old windows do for the house?”

NH: “Roughly two-thirds the air infiltration was reduced.”

LG: “Is this typical when you see a house just replace the windows?”

NH: “I have never seen this before. I am very impressed with the amount of leakage that was reduced from this repair. This is really, really impressive.”

So a 66-percent reduction in air infiltration by just fixing up the old windows.
Matt Grocoff is pretty happy.

MG: “I think it’s a lot better than new windows because we’ve proven you can make these old windows way more energy efficient and for a lot less money.”
LG: “But that’s not today’s project. Today’s project is putting these storm windows on which, I have to say, really look nice.”

MG: “It looks great! The house looks amazing right now, and especially in a historic district, putting a good storm window on is accepted by a lot of historic associations. The big bang for the buck that we’re going to get out of these storm windows is the Low-E glass that we have and a little bit of thermal insulation by creating a secondary glazing. What that means is that we have almost the equivelent of a dual-pane window.”

LG: “You mentioned Low-E glass. What’s that and what does it do?”

MG: “Low-E stands for low emissivity and what that means is that Low-E glass is just an invisible coating that keeps the heat from coming into your house and heating it up like a greenhouse. I can show you right here. If you put your hand here, we’ve got just a single pane up right now.”

LG: “Yeah, I can feel the sunshine coming through.”

MG: “And you can feel the sill, and you switch this up, pull the sill down with the Low-E glass, you can feel almost instantly how much cooler it is. You don’t get that greenhouse heat coming through.”

LG: “Cool.”

MG: “The other cool benefit is that it filters out all the UV light so it prevents your furniture from getting bleached and everything. We’ve got that red sofa over there facing a south wall. So, we could use all the help we can to help our furniture from fading.”

I don’t know about you, but when I think about storm windows, I think of those old bare aluminum windows that just weren’t all that attractive. Those days are past. Bill Trapp with the George W. Trapp Company supplied these new windows… and he says they come in a lot of colors to match paint schemes.

BT: “And we have people from all over the country calling us right now, getting storm windows in grey and red and green and all these different colors. And also, there are different levels of storm windows as well and I like to think we make the tightest one out there.”
LG: “Well, I can’t verify that, but they did pass the ole Matt Grocoff test, so Matt that’s the windows. Thanks, and I’ll talk to you on your next project on the house.”

MG: “Thank you, Lester, and here’s to staying cool.”

Lessons From a Skyscraper

You might have heard the Sears Tower
in Chicago is now called the Willis
Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental
facelift that could cut eighty-percent
of its energy use. You might wonder:
what could a homeowner learn from what
the Willis Tower is doing? Shawn Allee thought it wouldn’t hurt to ask,
and went on a tour for the answer:

One of the co-owners of the Willis Tower is John Huston. He says there’s plenty for
people to learn from the tower’s green rehab plans. To start – we’re at the base of the
tower, and we’re craning our necks up.

“We’re facing north. We’re looking at a hundred and ten floors, so that’s 16
thousand windows in total.”

Huston says those windows are the old single-paned kind common in 1974 – back
when the Willis Tower was finished. In the summer, the windows let heat in, and
during the winter, they let heat escape. And that black metal you see in photos? It
does the same thing.

Huston: “The building is clad in aluminum if you went outside in the winter, you
certainly wouldn’t want to wear an aluminum ski jacket.”

Allee: “You’d freeze.”

Huston: “Exactly.”

So, Huston says the first thing they’re gonna do at the Willis Tower is what he calls
“tighten the building’s envelope.” It means insulating the building from the outer
walls and replacing the windows – all sixteen thousand of ’em.

“It’s an incredible job. That’s what we have to change in order to conserve the 80%
of energy that we anticipate doing.”

Huston says energy consultants pretty much give homeowners the same energy
advice. He says, the nice thing is, once you do that it’s easier to figure out what’s
next.

“Watch your step.”

Huston takes me into the guts of the Willis Tower. This is where it’s heated and
cooled. He says since the building’s gonna waste less energy, he won’t need such
powerful equipment.

Huston: “A lot of what’s in here will disappear or shrink.”

Allee: “So what is this?”

Huston: “This is an electric boiler. It provides hot water to heat the building. Each
one of these consumes enough electricity to heat and light a town of 6,000 people.
We have eight of these throughout the building. It’s not just the boilers. in this
section behind us, you have all the pumps that move hot water throughout the
building. Each one of those pumps is hooked to an electric motor, and 50% of them
can be eliminated.”

Huston says the take-away here is that once a building requires less energy to heat
and cool it, the other savings can kind of cascade from that.

But there’s another lesson homeowners can learn from the Willis Tower’s green
rehab.

The architecture firm that planned this project is called Smith and Gill. Gordan
Gill tells me, their work was made easier by the fact the Willis Tower owners keep
records of their power use.

“When you’re designing something new, you’re predicting the performance of
something. Here, you can actually test it, since you have records of how much
energy was spent, how much energy was used – you know where you stand, exactly.
And so now, you can do mock-ups and tests and things like that.”

Gill says that’s a good reason for homeowners to hold onto their power and heating
bills, too. He says if you’re confident in your actual costs and likely savings, you’re
more likely to follow through with your rehab project.

“And that’s important because you’re avoiding the obsolescence of these buildings,
and I think that’s true from everything like Willis to people’s houses.”

Rethinking Window Replacement

  • Jack Spicer of Preservation Chicago is on a campaign to save the venerable 'wood frame window,' like these on his Chicago home. (Photo by Shawn Allee)

Each winter presents some homeowners with a choice: whether to replace old,
wooden windows with modern, energy-efficient ones before cold winds blow
again. Each year, more homeowners choose the replacement windows, often made from vinyl or aluminum. Shawn Allee found some historical preservationists want homeowners to think twice about that:

Each winter presents some homeowners with a choice: whether to replace old,
wooden windows with modern, energy-efficient ones before cold winds blow
again. Each year, more homeowners choose the replacement windows, often made from vinyl or aluminum. Shawn Allee found some historical preservationists want homeowners to think twice about that:

If you think century-old windows have to be rickety and leaky, Jack
Spicer would like you to come to his place.

He’s eager to show off windows on his Chicago two-flat, built in 1908.

“So, here’s an example of the way an old-fashioned wood window
looks from the outside a hundred years later. These windows are
longer-lasting and obviously better looking than any replacement window you
can find.”

It’s no surprise Spicer makes this pitch.
He’s with a group called Preservation Chicago, and he’s on a campaign
to save wood-frame windows from the onslaught of vinyl and aluminum-framed
replacements.

Spicer’s losing ground, even in his own neighborhood.

“This apartment building replaced their windows. The next building
replaced all their windows. If you look across the street at this huge
courtyard building, there’re about 48 units in there. Those windows were
fine, and those windows are now trashed. They went into a dumpster and are
now in a landfill somewhere.”

But if old wood-framed windows are so great, why do so many US homeowners
replace them?

“Somebody told them it would save them money if you put in brand-new
replacement windows. Everybody’s taught that – you read about it, you
see the ads. All the replacement window (companies) tell you, if you’re
American and you love your children, you’ll replace your windows. Well,
we’re getting over that now, I hope.”

Spicer insists replacing your windows is not an environmental slam dunk.

He says if old wood-frame windows are properly sealed and have storm
windows, they’ll hold heat almost as well as replacements.

I ask Spicer for numbers on this, and he sends me to Mike Jackson, with
Illinois’ Historic Preservation Agency.

“Several years ago, Vermont as a state did a study and they looked
at repairing windows, adding storm windows, replacing windows, and what it
really came down to was, how leaky are your windows? If they were
reasonably tight, there wasn’t a lot of savings to replacing your windows
at all.”

Jackson says a new furnace or insulation are better pay-offs, and
replacement windows often last just a few decades.

“We’re throwing away items that lasted for a hundred years with
simple technologies and replacing them with more complex things with
shorter life spans. In our line, the reason they call them replacement
windows is because you have to keep replacing them.”

Well, people in the replacement window industry don’t take kindly to
this.

One rep told me the short life span of replacement windows is overblown –
high quality ones last longer.
And he told me, if energy prices rise in the future, replacement windows
become more competitive.

So, is it worth replacing old, wooden windows?

“There’re many factors and that’s why it’s, in our opinion,
not so clear-cut.”

Christian Kohler studies window technology at the Lawrence-Berkeley
National Laboratory.

He says replacement windows are better on energy, but it could take decades
to get a good payback and by that time, you might need to replace them
again.

Anyway, Kohler says there’s an alternative.

If your wood windows are in good condition, you can add storm windows that
have what’s called a “low – E” coating.
The coating helps retain heat.

“It’s applied to glass and it’s virtually invisible. It
doesn’t have a color or anything.”

Kohler says if preservationists want to keep wood windows around on account
of their looks or long-term value, it still makes sense to crack down on
leaks and get good storm windows.

It doesn’t make sense to waste energy on account of beauty when you
don’t have to.

Getting Solar From Your Windows

Some researchers say they’ve found a way to make every window

in a building gather solar energy. Lester Graham reports:

MIT engineers say they can coat plastic or glass to redirect sunlight to the edges of a
window – to solar cells.

Instead of using a whole panel of expensive solar cells, the cells could just be aligned
just along the edges. The system could be used for solar panels, or could be used as
windows on tall glass paneled buildings.

Marc Baldo is the team leader at MIT.

“We think that this is a very practical and simple technology. It just relies on simple
coating processes. We have to develop techniques to, you know, manufacture and
integrate solar cells on the edges. But we’re optimistic that this might be useful within,
sort of, two to three year time frame.”

The researchers outlined their findings in the journal, Science. They say the focused
light at the edges really increases the electrical power obtained from each solar cell.

Energy Efficiency Often Overlooked

A new study suggests we could reduce our
energy use by 15% a decade. But Lisa Ann
Pinkerton reports many people don’t realize it’s
an option:

Experts call energy efficiency the invisible powerhouse. They say people and policy
makers don’t notice efficiency as an energy solution, because its impacts aren’t
tracked. Plus, it’s an option that’s built into things like energy efficient windows and
appliances.

“Energy efficiency is imbedded in all of the products that we use every day that we don’t
generally see it.”

That’s Karon Ehrhart-Martinez, co-author of a new report from the American
Council for an Energy Efficient Economy.

She compiled data from 2004, the most recent available, and found 300 billion
dollars of investment saved the same amount of energy that 40 power plants could
generate in a year. Ehrhart-Martinez says that’s just a fraction of the energy we
could save, if we chose more energy efficient options when we buy.

Lofts Attract Urban Renewal

  • Lofts are no longer just structures with large windows and exposed brick. Lofts are quickly becoming a symbol of the lifestyle of the young, urban professional. (Photo by Lester Graham)

In cities across the nation, old warehouses, factories and other buildings are being turned into brand new luxury loft apartments, and for many urban areas, those apartments are a big part of trying to get people to move back to cities from the suburbs. The Great Lakes Radio Consortium’s Nora Flaherty has this report:

In cities across the nation, old warehouses, factories and other buildings are being turned into brand new luxury loft apartments. And for many urban areas, those apartments are a big part of trying get people to move back to cities from the suburbs. The Great Lakes Radio Consortium’s Nora Flaherty has that story:


Abby Cook is taking a tour of the Union Square Condos.


“…finished the dining area, old basketball hoops and signs throughout the building, so…”


The condos are being built in what used to be a high school, and when they’re finished, the apartments will have a lot of the things that lofts are known for. They’ll have high ceilings, hardwood floors, big windows and exposed brick.


“It’s a great use of the building, it’s a neat idea and just the uniqueness, I think of it.”


Cook is excited about the idea of moving to downtown Grand Rapids, Michigan. She lives in the suburbs now.


“Location is key, I think. Being that I am a young person, and I go out a lot, being close to downtown, just being close and the convenience is huge, just huge.”


Developers all over are building these kinds of lofts in empty city centers. That’s because lofts are thought to attract a group that’s become kind of a holy grail to urban planners: young, educated, professionals like Abby Cook. They’re often willing to live in neighborhoods that other affluent people shun, and it seems, they love lofts. Julie Hale Smith is with Michigan’s housing development authority.


“Our main target goal was to increase population in our urban centers. When we looked around at other cities in the country that we were emulating, we noted that one of their linchpins of revitalization was the redevelopment of historic buildings or the kind of faux-lofting of new, or newer buildings to provide that kind of lifestyle, that kind of urbanist lifestyle for folks that chose to live in those kinds of dwellings.”


You hear the word “lifestyle” a lot when you talk about lofts. In fact, they’ve become almost synonymous with a certain lifestyle, and not just in the minds of developers and urban planners.


FLAHERTY: “When you think of loft apartments, what words do you think of?”


PERSON 1: “Urban living.”


PERSON 2: “Maybe urban contemporary types, younger…”


PERSON 3: “Young, urban, hip.”


PERSON 4: “Maybe en vogue for city living, kind of stylish…”

But what is it about lofts? Doug Kelbaugh’s the dean of architecture and urban planning at the University of Michigan.


“Lofts have a certain cache… they started in London and New York, where older manufacturing buildings or warehouses, in the case of London, were converted by urban pioneers, often artists, into large, open spaces, typically without separate rooms, and now it’s become sort of a lifestyle issue.”


But luxury lofts like Union Square are a far cry from the gritty artists’ lofts of 1970’s New York. They often have amenities like pools, gyms and game rooms.


“What will happen, is you’ll come up this stairway – there’ll be a landing here – and then there’ll be a second stairway that goes up through the roof to your private rooftop deck…”


Developers often like to call any apartment with big windows and exposed brick a “loft.” University of Illinois Geographer, David Wilson, says it’s all a matter of marketing, that developers aren’t just selling an apartment, they’re selling an identity.


“Developers and builders look at them and they see certain physical attributes: high ceilings, large, expansive windows, and so forth, and they seize upon the idea of marketing these physical attributes. And the marketing process hooks up to the notion of, ‘Let’s play to the identity of these people. Let’s make them appealing, let’s make them attractive.'”


So when people see apartments that look like lofts, they don’t think about washing those big windows, they think of having the hip, urban lifestyle that the windows imply. Take Hannah Thurston. She’s a 23-year-old student. She and her husband are putting down a deposit on one of the Union Square apartments.


“I’m hoping that the other people moving in will be great neighbors. Obviously, we’ll have a lot in common being young professionals, obviously there are a lot of nice perks.”


But whatever developers’ motivations, and whatever people might think of them, lofts are succeeding at one thing: they’re bringing at least some new people many of the nation’s abandoned city centers.

New Insulating Material Could Save Energy

A new insulating material could cut down on home heating
costs and save on materials in construction. The Great Lakes Radio Consortium’s Katherine Glover tells us about Aerogels:

A new insulating material could cut down on home heating costs and save
on construction materials. The Great Lakes Radio Consortium’s Katherine Glover
tells us about Aerogels:


Aerogels look like frozen smoke, and feel like styrofoam. Up to ninety-nine
percent of an aerogel is empty space. This makes it an excellent insulator. Last
year, the first aerogel jacket hit the market. And aerogel footwear inserts are used
by the U.S. military and the Canadian National Ski
Team. Ed Hogan is the marketing manager of Aspen Aerogels.


“Everybody knows how much cold feet can spoil an outing, right? And this stuff
is so thin, you can put it in a shoe or put it in a boot, and you hardly notice it.”


Because they’re new, aerogels are still expensive relative to other materials. The
company says once they gain in popularity and the price goes down, they could be used
as insulation in walls and the clear form could be used in windows. This could cut down
dramatically on heating costs. And, because aerogels are so thin, the company says
houses could be built with less lumber. That’s because less lumber would be needed
to make room for aerogel insulation.

Survey: Parents Missing Important Asthma Triggers

New research suggests that while parents of children who have asthma try to protect their youngsters from the things that trigger attacks, those measures often aren’t very helpful. The Great Lakes Radio Consortium’s Michael Leland reports:

Transcript

New research suggests that while parents of children who have asthma
try to protect their youngsters from the things that trigger attacks,
those measures often aren’t very helpful. The Great Lakes Radio
Consortium’s Michael Leland reports:


Researchers at the University of Michigan found 80 percent of the
parents they surveyed were doing something to prevent attacks, but
often missed important measures. For example, a quarter of the parents
said a smoker lived in the same house as a child with asthma, but they
hadn’t done anything about it.


In one case, the parent of a child with pollen-triggered asthma bought
a new mattress cover, but didn’t close windows to keep pollen out of
the house.


Dr. Michael Cabana is a U of M pediatrician who led the study. He says
many parents also needlessly buy products they think will lessen asthma
symptoms.


“A lot of times, parents may get more information from other commercial
sources more often than the time they have to spend with either their
primary care doctor or their doctor who might be a sub-specialist in
asthma. So I think physicians have to do a better job putting that
information into perspective.”


Dr. Cabana suggests parents talk to their child’s doctor about asthma
triggers before spending money on asthma-related products.

Do-It-Yourselfers Reuse Scrap Materials

In springtime, many homeowners’ thoughts turn to home improvement projects. That typically means a hit in the wallet, and for some, guilty feelings about consuming too much. Most do-it- yourselfers saw up a lot of trees in the lumber they use. And they use other materials that affect the environment. But there are ways to keep more green in your pocket, and boost your green conscience.

In springtime, many homeowners’ thoughts turn to home improvement projects. That
typically means a hit in the wallet, and for some, guilty feelings over consuming too
much. Most do-it-yourselfers saw up a lot of trees in the lumber they use. And they use
other materials that affect the environment. But there are ways to keep more green in
your pocket, as well as a green conscience. As part of an ongoing series called “Your Choice; Your Planet,” the Great Lakes Radio Consortium’s Cari
Noga reports:


If you’ve ever sat in a high school gym, you’ll likely get a sense of déjà vu when you
walk into John Patterson’s home. That’s because in its former life, the house’s flooring
was high school bleachers. Cleaning them up was a chore. Patterson says he and his
wife filled up a five-gallon bucket removing the gum wads from the 20-foot yellow pine
planks. But Patterson says the work was worth it…


“What I like about them the best is the wood is so old, because they were in the school
for like 40 years. I hope they stay here for 40 years. You can’t replace them, or regrow
trees this long and tall. It’s something I’m really proud of doing.”


The floor is just one part of the couple’s overhaul of their home. Two summers ago they
stripped the tiny ranch-style home down to the studs. They nearly doubled the square
footage, and added a second floor. The windows, siding and even the 2 by 4s, are reused
or recycled.


A growing number of homeowners are combining a do-it-yourself attitude with an
environmental ethic. Instead of shopping at big box chain stores, they go to auctions and
used building material stores. They buy everything from bathtubs to doors to, yes, even
the kitchen sink. Patterson’s wife Sarah Goss is the scavenger, scouting out the stuff for
him to install. For her, reuse has been a lifelong value.


“I think it’s upbringing. You just grow up feeling a little guilt if you overuse your
resources…any way you can conserve or be a part of that, I feel like it’s an added plus.”


They’re not the only ones who think this way. Kurt Buss is president of the Used
Building Materials Association. He says the reuse movement is spreading as
communities nationwide try to reduce landfill volume. Up to 40 percent of landfill space
is construction debris.


“You don’t throw away newspapers and tin cans. You shouldn’t throw away your house.”


Buss says reused materials can be better quality, too.


“More often than not the wood is old growth lumber, which is certainly preferable to
much of the lumber that you see in lumber stores today which is speed grown on tree
farms… So there’s premium materials that are available with environmental benefits
attached.”


So, reused materials are often higher quality, and go easy on the environment.
They also cost a lot less – typically half of what the same item would cost new.


Still, not everyone’s sold immediately. There’s a lot of sweat equity that offsets the cost
advantage. John Patterson and Sarah Goss worked a long time scraping off all that
bubble gum.


Then there’s getting over the fact that most of the stuff is someone else’s discarded
material… their trash.


Bruce Odom owns the Michigan store where Patterson and Goss found many of their
materials. He says many shoppers walk in skeptics, but become believers.


“You see a lot of one party tugging the other one along, and the other one saying, ‘No,
no, I don’t know about this,’ whether it be the husband or the wife. You see a lot of that.
And yeah, you do need to realize that it’s all done and installed, you probably aren’t
going to recognize the difference except in your checkbook.”


If you’re making a list of things to do around the house, you can find reused materials
stores in at least 30 states. A visit to one might deconstruct the perception that newer is
better.
