When people talk about making their home energy independent, they often talk about solar panels and wind turbines. But before all of that, a home has to be tight. That’s not as exciting, but necessary. Lester Graham is following Greenovation.tv’s Matt Grocoff as he tries to make his home the oldest net-zero-energy house in America.

When people talk about making their home energy independent, they often talk about solar panels and wind turbines. But before all of that, a home has to be tight. That’s not as exciting, but necessary. Lester Graham is following Greenovation.tv’s Matt Grocoff as he tries to make his home the oldest net-zero-energy house in America:

The note on Matt’s door told me to come on in and head for the basement. Matt’s 110 year old home has what’s called around here a “Michigan basement.” Basically, cement floor, stone walls, low ceilings. Not glamorous.

Matt is spraying expanding foam insulation up in that area where the floor framing sits on the foundation. The sill plate… which is basically nothing more than one-and-a-half inches of wood between inside your home… and the great outdoors.

“There’s no insulation between your house, or your living part, and the foundation itself.”

Maybe you’ve been in the basement of an old house and sometimes you can actually see daylight through the sill plate in places. Those leaks need to be sealed. That could be done with caulk. Then the area needs to be insulated. That could be done with fiberglass insulation.

“What we decided to do is to do both at the same time, seal and insulate, is to use a do-it-yourself spray foam insulation kit from Tiger Foam. There’s plenty of professionals out there, and for most people, that’s what I’d recommend you do, go to the professional. If money is an issue or if you’re a really handy person, these spray foam kits are fantastic.”

The foam insulation kit costs about 300-dollars. It’s basically two tanks -each about the size of a propane tank you’d use for an outdoor grill. A hose from each tank is attached to a spray gun that mixes the chemicals. The chemicals mix as they come out and the make a sticky foam that expands into nooks and crannies and then hardens after several minutes.

“Way easier than I thought they were going to be, by the way. I was actually terrified. I went back and read the instructions three – four times. And when I started spraying, it wasn’t that bad.”

“You still ended up with a goof, though.”

“I did have a goof. There was a little bit of foam there, dripping, when I forgot to turn on one of the canisters, but what ya– c’mon Lester.”

Matt’s goof means he’s going to have to wipe up some of the mess and spray again. But it’s not a disaster.

If you’ve got a big job… maybe new construction or a remodel that takes it down to the studs… you might want to consider a professional.

John Cunningham owns Arbor Insulation in Ann Arbor, Michigan. He says, sure, if you’re up to it… do it yourself.

“You could assume that it’d be cheaper to do it yourself and the kits are a really good option, especially for people that have smaller projects or they’re looking to do the work in a very specific time frame or in a distant location for instance.”

But the professionals are recommended for those big jobs. And right now there are federal tax credits for spray foam insulation– 30-percent up to 15-hundred dollars. That credit is limited though.

“The tax credit is available for the material only, so the contractor should be separating out the material and the labor. Also, there are additional incentives from some utilities and more incentives coming down the pike.”

Some states and even municipalities are considering incentives.

One final note… to use the spray foam, Matt Grocoff is decked out in a white haz-mat suit, latex gloves, goggles and a respirator…

“You’ve got to take all the safety precautions. You’ve got to wear your goggles, your suit. And it also can be messy too. Any overspray that gets in your hair will stay in your hair.”

And as he zips up, I get the hint that Matt has to get back to work.

“I do. I’ve got 30 seconds before this nozzle sets up. So, Lester, thanks again.”

“Sounds like my cue to get out of here. That’s Matt Grocoff with Greenovation-dot-TV. I’m Lester Graham with The Environment Report.”

“Thanks Lester.”

Home Weatherization Gets Snagged

The Recovery Act called for a multi-billion dollar home weatherization program. It was thought that putting insulation in older homes was the ultimate “shovel ready” project to help jump start the economy. But as Mark Brush reports, so far, it just hasn’t worked out:

The Department of Energy’s Inspector General found the data alarming.

Of the ten states receiving the most money for home weatherization – eight of them weren’t even at two percent of their goal.

One reason for the hold-up is bureaucracy. There’s a law that says if you get federal money – you have to pay workers a “prevailing wage” or a fair wage. And there was confusion over how much to pay people.

Don Skaggs is with Ohio’s Office of Community Services. He says most states waited until the issue was resolved – but Ohio didn’t wait:

“So we decided to go ahead and do production. And then once we understood what the requirements were, we would go back and retroactively adjust those wages for those staff, which is what we did.”

So Ohio’s on track – but most states are not. The Department of Energy said it’s working on these problems – and expects things to ramp up soon.

Tax credits for making your home
more energy efficient got a lot
of early buzz. The promise of up
to 1500-dollars back for insulation
and windows or efficient furnaces
led to a flurry of advertising.
Tamara Keith looks
into what might be stopping people
from taking advantage of the tax
credits:

My husband and I recently bought an older house that could no doubt use
some weatherizing. So, I called up Reuven Walder at EcoBeco.

(sound of door opening, people saying hello)

He’s a home energy auditor. He identifies ways to make a home more
efficient.

“I joke around, I consider myself an energy efficiency social worker.”

And he’s been getting a lot of calls lately from people like me – looking
to take advantage of the tax credits.

“Let’s look around the house and you can point out some things that are
of concern to you.”

Walder has all these cool tools, like an infrared camera that can see where
the insulation isn’t doing its job. He finds plenty of trouble spots,
including one in the attic.

“And if you put your hand in this little pocket here you can feel nice
cool air.”

That’s not supposed to happen.

“I’ll be honest with you. When I find these kinds of things, it makes my
day, because we get to fix them.”

Well, not all the time. Walder says only about a third of the homeowners he
works with actually follow through on his recommendations.

“I have talked to numerous homeowners and their primary reason for not
doing it is money.”

He says the tax credits are a great shot in the arm, but, for many people,
it’s just not enough. Part of the problem is, for simple weatherizing –
insulation, weather stripping, windows – the tax credits apply to 30% of
the cost of materials, not the labor. And labor is actually the most
expensive part.

“Our economy is just so slow right now that people are just hesitant to
spend any amount of money because, regardless of the incentive, they’re
still going to have to spend a lot of money to make the improvement. It’s
not going to cover a significant portion of the cost.”

At this point, federal officials don’t know how many people have been
inspired by the stimulus package to do work on their homes. They won’t know
until everyone files their taxes in April.

“It’s definitely driving additional business.”

Matt Golden is president of Efficiency First – the national association for
the home performance retrofitting industry. But he isn’t totally sold on
the way the stimulus package is distributing the tax credits.

“The biggest incentives are for the most expensive fanciest equipment and
as you move towards the most cost effective stuff, you get much smaller,
incremental incentives.”

So, there’s big money for solar panels and geothermal heating systems. And
if you want to put in a tank-less hot water heater or a super efficient
furnace, here labor costs can be counted towards tax credits. Golden says
the smallest credits go to insulation and other simple steps.

“It’s actually kind of an impediment to the type of retrofitting projects
that have the biggest return on investment, bang for the buck and create
the most jobs.”

In my house, Walder estimates we need almost $6,000 worth of work. But,
because not all of it qualifies, I’ll only get $600 of it back from the
government – but we won’t see the money until tax season.

I’ll admit – it’s a lot more money with a lot less of a tax benefit than I
was expecting, and that’s probably what’s giving some homeowners pause.

Soon, you’ll be able to buy
a sort of raygun to detect heating
leaks in your home. Jessi Ziegler reports on a Thermal Leak
Detector:

This tool looks like a little toy raygun, and it shines beams of light
that read the temperature around your house.

Scott Pollard is the Senior Product Manager at Black and
Decker, which makes the tool. He says it’s really easy to use.

“Shine it on the wall, it starts off with a green light, and as they
move it from their wall to their window, or door, or around pipes,
or floor, or ceiling, the color will change to red if it hits a hot spot,
or blue if it hits a cold spot.”

And, if you think you the little leaks don’t really matter, well,
Pollard’s research shows that if you add up all the little cracks
and leaks in a typical home, it equals a hole the size of a
basketball.

The EPA says that homeowners can save 20% on their heating
and cooling costs if they seal air leaks and insulate their houses.

Beautiful Drafty Old Houses

  • Historic homes like James Boyd Brent's pictured above are beautiful, but not very energy efficient. (Photo by Diane Richard)

People who choose to live in historic houses tend to appreciate old-world
charm. But that charm often comes at the expense of energy efficiency.
Old windows and doors let in cold drafts and leak out warm air. So
homeowners are often forced to balance their interests in historical
integrity and aesthetics against their environmental principles:

People who choose to live in historic houses tend to appreciate old-world
charm. But that charm often comes at the expense of energy efficiency.
Old windows and doors let in cold drafts and leak out warm air. So
homeowners are often forced to balance their interests in historical
integrity and aesthetics against their environmental principles:


My neighbor James Boyd Brent had me over to his house the other day.
He lives in a beautiful old farmhouse that’s about 130 years old. It’s got tall
ceilings. Rickety staircases. Original windows, floors and doors. But what
makes it cool also makes it cold. Really cold.


James recently had an energy audit done. Today he’s showing me all the
problems he needs to fix. He greets at the door me wearing a knit hat. And, even
though he’s lanky, he looks a bit padded.


“Well, I’ve got a vest, like a t-shirt, a shirt – a very thick shirt, actually –
then a sweater and another sweater. So that’s just four layers.”


That’s because it’s really cold inside. James is a Professor of Design at the University of Minnesota. He has a
taste for beautiful old things. But that puts him in a bind. Does he sacrifice
what he loves about his old home to improve his green cred? Or does he
simply live with the howling gales blowing down his hallways?


It’s a dilemma he confronts every winter. Preserving aesthetics versus
conserving energy. He says it’s not a strict either-or. And he’s willing to
install modern conveniences when it makes sense:


“I’m not interested in being faithful to some sort of bourgeois idea about what
history is.”


To prove it, he shows me the ultra-high-efficiency furnace and water
heater he recently installed in his basement. But I notice something else
down here:


Richard: “I see light coming through there.”


Brent: “Yeah. Exactly. That’s daylight. There’s not even a window. There’s
nothing. There’s just a hole.”


Upstairs, it’s bad enough. James’s house rarely tops 60 degrees. Down
here though, I can see my breath:


“Last year it froze down here. Rollicks’s cat water froze solid. I saw her
once sort of tapping it with her paw with a look of irritation.”


We leave the basement and its gaping hole for another day. Today’s chores start in the
kitchen:


“Okay, first of all, I’m working on this door here. Actually, as you can see, I’ve
sealed this all around in layers, actually. But I’ve just decided it’s not
enough. It’s still letting in great currents of cold air coming through. So I’m
going to actually seal the whole thing, right on the outside here. I’m just
sticking that down here a bit more strongly on the bottom. Because actually, that’s where
the cold air is coming through.”


The energy audit helped James figure out where he was losing the most
heat. Windows, doors, baseboards, walls and attic all were culprits:


“The basic thing is, that’s what came out of the energy audit. That all of
this sort of stuff that I’m doing now is basically, um, the sign of a complete
loser.”


Richard: “What do you mean?”


Brent: “Well, in the sense that it’s taking up all of my time and I might as well live
in a shack.”


James is not alone. Lots of people are in the same fix, loving their
beautiful home, hating that it’s as drafty as a barn.


I talked to Paul Morin about James’s frustration. Paul is a home energy
expert. He says the taping sheets of plastic over old doors and windows
should pay off:


“That really reduces the amount of air infiltration and also adds another
insulating layer. So that’s very effective.”


Paul says there’s lots more James can do, but taping up things is cheap and easy. Now, James is not looking forward to pulling down all the film next spring. But
he’s willing to keep doing it, because it’s the only way he can
balance his appreciation for the past and his commitment to the future:


“I mean, obviously I could heat this house just by cranking up the furnace and
not worrying. But it would cost literally thousands of dollars a quarter.
And also it’s just a complete waste of energy. I do have a sort of sense of
the connection between wasting money, and also wasting energy, wasting resources
and being wasteful.”


So, like a lot of people who love their old homes, James’ weekends will
be spent sealing up his house. It’s that or spend a lot of
money on expensive upgrades, or wasting money on heat that escapes
through the drafty windows and doors. And that big hole in the
basement.

‘Mcmansions’ Deflate Energy Savings

  • Many people are now making more energy-conscious decisions for their homes. However, one consideration that gets overlooked is the actual size of the house. (Photo by Bjarne Kvaale)

Every year, Americans build about one and a half million single-family homes. One researcher says a lot of these houses are simply too big for American families and the environment. The Great Lakes Radio Consortium’s Shawn Allee reports:


When energy-conscious homebuyers look for a new house, they usually check for the right things: high-tech insulation, special windows, high-efficiency furnaces.


But one researcher suggests these homebuyers waste energy by buying more house than they need. Alex Wilson compared the size and efficiency of American homes for MIT’s Journal of Industrial Ecology. He says, since 1950, American families shrank by twenty-five percent, but their houses are now twice as large.


“If we’re significantly increasing the house size, our energy bills are still going to go up. So we lose the benefits that we would otherwise realize through these better technologies.”


He does hold out hope for bucking the trend toward miniature mansions. A number of architects want to make smaller homes more attractive through higher-quality design and materials.

New Insulating Material Could Save Energy

  • From lighter, thinner ski boots and other cold-weather clothing... (Photo by Adam Fowler)

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.

Report Finds White House Blocked Asbestos Warning

A recent newspaper report says that the White House stopped the
EPA from issuing a warning about widespread asbestos-contaminated
insulation last spring. The Great Lakes Radio Consortium’s Tracy Samilton
reports:


Zonolite insulation was produced in this country from the 1940’s through
the 1990’s, and almost all of it was made from ore that came from one mine
in Libby, Montana. Thousands of miners were killed or sickened because
the ore was contaminated with an extremely lethal asbestos fiber.


But it was only last year that the EPA decided to issue a public health
emergency warning to residents and workers who could come in contact with
Zonolite insulation in homes where it had been installed.


A St. Louis Post Dispatch investigation revealed that the White House Office of
Management and Budget intervened, and the EPA never issued the warning.
The Post Dispatch reports that EPA chief Christine Todd Whitman was
outraged by the decision.


Hundreds of thousands of homes in Michigan and Illinois probably have
Zonolite insulation. The insulation is often strewn loose in attics.
It’s silvery-brown and comes in feather-light pieces ranging from the size
of a pea to the size of a nickel.
