More people are putting up solar
panels on their houses. But in
some places around the country,
solar panels are getting blocked
by homeowners’ associations. Mark
Brush has more:

It comes down to aesthetics for a lot of these associations. They have rules about how tall your grass can be, when trash cans can be set out, and what color your house can be.

Sometimes these associations just don’t like solar panels, or they worry they’ll be sued by neighbors.

Raymond Walker is a lawyer for Standard Renewable Energy. It’s a fast growing solar installation company in Texas. He says these restrictive rules can cost jobs and money.

“It doesn’t seem at first blush like it ought to be a big problem, in fact, you know, it seems like it might be sort of a silly issue, but we lost about $500,00 in installation money in 2008 because of this, and we’re projecting that we’ll lose about two million dollars this year.”

There are some state laws that say homeowners’ associations can’t stop the construction of solar panels, and now some legislators want to see a federal law passed.

Green roofs are a popular, but
expensive, way for building owners
to prove their green credentials.
Shawn Allee reports some
researchers feel they might do even
more environmental good than they
thought:

The rock, soil and tiny plants in a green roof help insulate a building.
That can cut heating and cooling costs.

Researchers at Michigan State University think they’ve found another
benefit, too.

Brad Rowe says the tiny plants absorb carbon from the air. Rowe says the
plants are small, so this carbon sequestration effect is small, too. But
he says green roofs are still better than plain-jane roofs.

“You have all these roofs everywhere and basically, they’re doing nothing
– they’re essentially dead. So, putting plants on them is one way to
sequester carbon above ground, in the leaves and stems, the roots, and even
in the soil that’s on top of the roof.”

Rowe says if Congress ever puts a price on carbon emissions, green roof
owners might get credit for sequestering carbon – and that could cut a
green roof’s high price tag.

It’s estimated, every year, somewhere
between seven and eleven-million tons
of old asphalt shingles end up in landfills.
Some states are short on landfill space.
Lester Graham reports, they’re now
encouraging grinding up and recycling
the old shingles:

Two-thirds of American homes have asphalt shingle roofs. They last twelve to twenty years before they need to be replaced.

Since most of the material in asphalt shingles is the same stuff used in asphalt pavement, that’s where they’re going.

(sound of machinery)

New businesses are popping up across the nation that take the shingles.

Chris Edwards is co-owner of Ideal Recycling in Southfield, Michigan. He says roofers can dump old shingles at his place cheaper than taking it to the landfill.

“And then they can also sell it to their customers that they are recycling and it’s green. So it does help the contractors quite a bit.”

Several states are studying how the material holds up for asphalt roads, but for now most of the singles are mixed in asphalt used for parking lots.

Greening the Capital City’s Rooftops

Green roofs are increasing in popularity across the US, especially in cities, where
there’s not a lot of space for gardens. Sabri Ben Achour explores the trend in
Washington, DC, where the city government is promoting the practice for it’s
environmental benefits:

In Washington, you can see flowers and vegetables growing on top of homes,
businesses, even government buildings throughout the city. DC officials say
Washington has nearly 70,000 square feet of rooftop greenery. Only Chicago has
more.

One big fan of these so called green roofs is a popular small hotel, Tabard Inn, just a
few blocks from the White House.

“There’s about 10 varieties of sedum on this roof.”

Sarah Murphy is giving a tour. She’s a horticulturalist.

“This is a very pungent oregano here on the corner, it looks heavily used.”

The city of Washington pays building owners about one-fourth of the cost of
incorporating greenery on rooftops. One big reason? Rainwater runoff.

Sarah Loveland works for an environmental consulting non-profit called DC
Greenworks.

She says Washington has what’s called a combined sewer system. The sewer
system doesn’t just take in what’s flushed down the drain, but also all the rain
running off roofs and streets.

“If you imagine that our sewage treatment plant has a dam, and the sewage system
combines with the storm water system before the treatment plant.”

So, when there’s a heavy rain, that dam at the sewage treatment plant overflows.

“You have both raw sewage and runoff from the streets going directly into the river
untreated.”

Three billion gallons of it a year, at one point.

The EPA sued the District of Columbia.

The city had to spend $150 million to address the problem. Part of that money goes
to green roof grants.

The green roofs slow down rain water – give it some place to soak instead of just
running off straight down the gutter. The city says roofs in the city prevent a million
gallons of storm water runoff from entering the Potomac River.

The roofs also insulate buildings – especially during the summer. Some studies
show they reduce energy costs by 20-30%. And they reduce the heat island effect in
the city, since they don’t get blisteringly hot like traditional roofs.

Green Roofs even offer some habitat for creatures, like bees.

Sarah Loveland with Greenworks, the consultant agency, says rooftop gardens are
also increasingly popular for growing food.

“Veggies are really popular, herbs are really popular – this is a trend that’s taking off
in the restaurant industry. There’s a lot of buzz around it.”

Blueberries and herbs abound in the rooftop gardens of the Tabard Inn, where Paul
Pell is executive chef.

(sound of celery chopping)

“Yeah, we go up and get whatever we want, so it’s fresh. We just climb out the
window when we need it. Chocolate basil goes with ice cream, nasturtiums go with
soups and salads.”

Washington has an advantage over some larger cities in its promotion of rooftop
gardens because federal law prohibits skyscrapers in the nation’s capital, so most
buildings don’t cast shadows over their neighbors.

As a result, most rooftops are sunny – all they need is greenery to soak up the rays.

Tax Incentives Put Solar Within Reach

Buying a solar system for your home still is not as simple or inexpensive as say picking up a new water heater. But solar energy advocates argue that the systems are affordable and obtainable for just about everyone – right now. Joyce Kryszak checked out that claim:

Buying a solar system for your home still is not as simple or inexpensive as say picking up a new water heater. But solar energy advocates argue that the systems are affordable and obtainable for just about everyone – right now. Joyce Kryszak checked out that claim:

You might say that sunlight is a trade mark for Cannon Design. The Western New York based firm designs some of the most solar friendly buildings in the world. But only now is Cannon using the sun for its own building.

Eric Lindstrom is Vice President of the company. He says it’s what their environmentally savvy clients expect.

“You know there’s a huge P.R. factor here that we can bring our clients in and say, you know, this is what we’re recommending to you, but we’ve done it ourselves and it works. That we didn’t just read it in a magazine somewhere and say this is what you should be doing.”

Lindstrom takes us up on the roof of the company’s building to have a look at the new system.

Up here we find solar panels. 140 of them. They’re stretched out from edge to edge, soaking up the rays.

Lindstrom says they generate about 5% of the energy the building needs. But he says even at that small percentage the company will recoup the roughly $17,000 investment in about three years.

The system’s total price tag is actually about $170,000. But Cannon Design got corporate tax credits and incentives that covered roughly 90%. After the pay-back period, Linstrom says the company will actually pocket money.

Back in the building they can watch the savings add up on the inverter meters inside. That got Lindstrom thinking. He got a bid on a system for his home. He’s decided against it for now because the payback would take about eight years. You see, businesses get more tax breaks than homeowners.

But some people say the payback time can be less. And sometimes it just doesn’t’ matter to them.

Joan Bozer was at the American Solar Energy Society Conference held in Buffalo, New York. Bozer was showing off pictures of her home’s $30,000 solar system. It cost her half that after incentives. The payback will take a while—about eight years. But Bozer says that’s okay.

“Because it doesn’t make any difference to me if it’s five years or ten years what the payback period is. I want the solar panels, like people in their house they put on the roof they want, or they put on what they want and this is what we want – solar panels on the roof. That’s how we want to do it.”

But as green-minded as she is, Bozer admits that federal and state incentives gave her the final push.

While everybody can take advantage of recent federal tax credits, state incentives vary. Some are generous, and some offer homeowners nothing. Some local governments are offering low-interest loans on top of the federal and state incentives.

Neal Lurie is with the Solar Society. Lurie says incentives are creating demand and that’s driving down the cost of solar systems.
He says systems cost about 30% less than last year.

Lurie says with lower prices and tax incentives, some homeowners can have solar without much – or no – money out of pocket.

But how soon will solar catch on with the masses? Lurie predicts in less than six years.

“We’ll see solar technology a low-cost provider of electricity, even lower priced than fossil fuels without incentives. I think that when that happens we’re going to see it go from being something that people are looking at and starting to do to something that is truly common-place, much more than people may actually expect today.”

Others think solar will really take off in just three years. Solar installers are already gearing up. Some say they’ll double their workforce by the end of this year.

Renting Rooftops for Solar Power

Some big utility companies are
looking at projects using more renewable
energy. Some are investing in solar on
the rooftops of their customers’ homes. Julie
Grant reports on one of the biggest pilot
projects in the nation:

Duke Energy plans to rent 425 rooftops from homeowners
and businesses in North Carolina to install and maintain
solar panels.

Dave Scanzoni is a spokesman for Duke Energy. He says
building a new nuclear or coal plant could take a decade.
But this solar project could contribute electricity to the grid in
just a couple of years.

“Instead of a big, main baseload power plant that we
traditionally think of, we have several hundred small, little
power plants. It’s distributed power plants, a different way to
distribute energy closer to the customer.”

If the project is approved by regulators, the money to pay for
it will come from ratepayers – an 8-cent hike on the average
utility bill.

Other utilities have rooftop solar projects in the works as
power companies begin to experiment to find ways to reduce
carbon emissions.

Growing a Garden on Your Garage

When most people put a new roof on
their home they usually use standard asphalt
or tile roofing. But other people are going
for something more natural. They’re planting
grass and flowers on their houses. Joyce
Kryszak talked with one builder in
Western New York who planted a green roof on
his garage to show his neighbors how it works:

About 90% of all residential roofs are made out of manufactured
asphalt.

But builder David Lanfear knows that nothing tops mother nature.
He makes roofs out of gardens.

Lanfear recently ‘installed’ one on his own garage roof, so his
neighbors could see the benefits. There are beautiful flowering
plants visible over the edge of the flat roof. Lanfear says they’ve got
the whole birds and bees thing going on.

“We’ve noticed a big increase in insects, butterflies, birds all
sorts of new birds that I haven’t ever seen. They’re up there
eating something. Bugs? But its kind of nice to sit on the deck
and watch this nature in the city thing,” said Lanfear.

But the living roof isn’t a novelty. Lanfear says the roofs are more
eco-friendly. He says a living roof provides a whole cascade of
environmental benefits.

“Especially in a downtown when you get a hard rainfall the water
washes off all at once. There’s nothing to absorb it. If you had
a roof like this it absorbs the water and let’s it off slowly. So, it
not only slows the runoff, it cools the water and it starts to filter
the water. It filters some of the atmospheric crud out.
Otherwise, you get super heated water rushing off into the storm
sewer, and then out into the river or the lake and effecting the
environment there,” said Lanfear.

Once his neighbors understood the concept, they stopped thinking
Lanfear was crazy. A few even offered to give him a hand planting
his roof.

First the roof was reinforced with used lumber. Next are the
waterproof barriers – a rubber membrane, a root barrier made out of
old billboards and some old carpeting. Finally, recycled, crushed
concrete is shoveled on to be used as soil for the plants to grow in.

It’s all sustainable. And the native plants require very little water or
maintenance.

Neighbor Deborah Bach loves to garden. So, she was happy to
pitch in. Bach says the concrete soil needs to be doctored to enrich
it. But they have a reuse idea for that too.

“My son works at Starbucks and they give out free grounds for
gardens. So, we’re going to try doing that to try to balance this
out. You know, using recycled materials and things that have
already been used,” said Bach.

Another neighbor stopped by to help. Alex Sowyrda is a high school
technology teacher who’s interested in the science of green roofs.
He plans to share what he learns with his students.

“I try to bring it into my curriculum at school and, hopefully, the
kids graduating high school now take this knowledge with them
and are able to make responsible choices in the way they build
and the way they design in the future,” said Sowyrda.

The living roof builder David Lanfear says it’s a concept that can grow
on anyone. Even people who grew up with more traditional roofs. He
says to start small – with a garage roof – or maybe even smaller.

“We all have little expanses of roof in front of windows. And in
the summer you might notice that when the window is open the
hot air blows in, a lot of that heat comes from that little bit of
roof. If we could just put sections one square yard of living roof
outside of our windows on the porch roof, that would make a
drastic difference in cooling our house – simple,” said Lanfear.

And pretty cheap. Lanfear says the cost of materials is about the
same as an asphalt roof. But he says there’s savings in the long run
because the green roof can last three times as long.

And he says it’s a whole lot nicer to look at.

Making Solar Power Mainstream

Solar panel technology has been around for decades…but not many
people have panels on their roofs. Solar energy is the ultimate clean
power source, but it’s also expensive and that’s kept most people away.
But regulators in one state are hoping to change that. The state’s Public
Utilities Commission recently approved a 3-billion dollar fund to give
homeowners and businesses hefty rebates if they install solar panels. It’s
the first program of its kind and size in the nation. The Great Lakes
Radio Consortium’s Tamara Keith reports:


A little over a year ago, Chuck Wingo and his wife Pam moved into a
new house in an innovative housing development. Their house, like all
the others in the neighborhood, is equipped with bank solar panels, built
right into the roof like shingles.


“These are the 2 meters that are on the house. It’s simple. One uses for
our usage, what we use, and the other one is from the solar panels, what we
produce.”


Chuck says sometimes he walks to the side of his California house and
just watches the solar meter spin.


“We check it all the time, what’s even better is checking the bills. The
bills are great, we paid 16-dollars for our usage in August, the hottest
month in Sacramento. So, it’s kind of cool.”


The Wingo’s weren’t big environmentalists before moving into this
house, but Pam says when she heard about this development, something
clicked.


“The idea just sounded, if you’re going to move, do it right at least. Do
something pro-active about where you’re going to be living and spending
your money. It’s really good for everybody, for the country. We all
should be living like this so we’re not wasting out energy.”


And many more Californians will be living that way, if the California
Solar Initiative lives up to its promise. State energy regulators approved
the initiative, which will add a small fee to utility bills in order to create a
3-billion dollar fund. That fund is designed to make solar panels more
affordable.


It starts by offering rebates to consumers who buy them. Bernadette Del
Chiaro – a clean energy advocate with Environment California – says
once those panels get cheaper, the marketplace goes to work…


“The problem with solar power today is its cost. Most of us can’t afford
an extra 20-thousand dollars to equip our home with solar panels, and
what we’re doing in California is saying, we’re going to get the cost of
solar power down. By growing the market 30 fold in the next 10 years,
we’re going to be able to cut the cost of solar panels in half.”


Last year, Governor Arnold Schwarzenegger tried to get the California
legislature to approve something similar. That plan got bogged down in
state politics … so he took it to the Public Utilities Commission. While
the commission can raise the money, there are some parts of this
revamped solar program that have to be legislated.


Democratic State Senator Kevin Murray has worked with the Republican
Governor on solar power issues. He says he plans to introduce a new bill
that would require solar panels be included as an option on all new
homes built in the state.


“Rather than some specialized left-wing alternative kind of thing, we want it to
be in the mainstream, so that when you go in to buy a new home, you
pick your tile and you pick your carpet and you pick your solar system.
So, that would have to be done legislatively and the other thing that would
have to be done legislatively is raise the net metering cap so that if you’re
selling energy back to the grid, you can get compensated for it.”


The new program would also target businesses, even farms. Public
Utilities Commissioner Dian Grueneich says she hopes this doesn’t stop
with California.


“I’m very, very excited. This is the largest program in the country
and I’m hoping that other states will look at this program as well, so that
it’s not just something in California but helping other states.”


And if the solar power initiative is a success in California, backers say
it’s good news for consumers all over the country. Much like the hybrid
car, made cool by Hollywood celebrities… California leaders hope they
can make solar trendy and more affordable for everyone.

Cooling the City With Green Rooftops

On the nightly TV news in large cities, the meteorologist sometimes talks about the heat island effect. That’s where all the blacktop roofs and asphalt parking lots soak up the heat and increase the temperature on a hot summer day. One major U.S. city is trying to do something to reduce that effect.

On the nightly TV news in large cities, the meteorologist sometimes
talks about the heat island effect. That’s where all the blacktop roofs
and asphalt parking lots soak up the heat and increase the temperature
on a hot summer day. One major U.S. city is trying to do something to
reduce that effect. To set an example, the mayor decided to start with
City Hall. The Great Lakes Radio Consortium’s Lester Graham reports:


Standing on the roof, eleven stories up, isn’t really far enough to escape
the noise of the city below. But this rooftop is an escape. It’s a garden, a
big one. There are even trees. Not in pots, but actually planted on… or…
in the roof.


Marcia Jiminez is the Commissioner of the City of Chicago’s Department of Environment. She says Chicago wants building owners to
do what they can to cool the city down… and planting gardens on the
roof is one way to do it. So that’s what the city did on top of City Hall.


“Well, the garden on the rooftop is addressing what we call an urban heat
island problem. By putting the garden with light colored pavers and the
green plants on top of the roof, we’re actually helping to use less energy
inside the building and it actually helps to keep the building cooler.”


Cooling down the building is just the beginning of this garden. Despite
being eleven stories up in the middle of downtown, the roof is alive with
bugs and butterflies.


“Actually birds and all of the insects, many of them, have found their
way up here. We’ve actually put up birdhouses to study what kind of
birds are coming to the rooftop garden. This is a place of
respite as well as a place to feed.”


The whole rooftop has become something of a lab. Scientists research
what animals have made a home here… and they’re monitoring how the
plants are spreading.


Kimberly Worthington worked on the City Hall project to see it go from
the drawing board to rooftop. She says they chose plants for color, form
and for survivability.


“The design that we went with was low maintenance, was what we were
looking for in our plant selection. And the landscape architects that were part of the design team focused on plants that would require less water. And they also wanted to keep as many native plants as possible. So, there are a lot of prairie plants up here.”


The Chicago City Hall rooftop project also reduces rain water runoff. 75-percent of a one-inch rain will be soaked up right here in the garden. That’s good because too much rain overflows sewers into Lake Michigan. If enough buildings in the city had rooftop gardens, stormwater runoff problems would be curtailed a bit.


While the city is touting the environmental benefits of its rooftop garden, in another part of the city a planned rooftop garden is all about people.


Brenda Koverman is with the Schwab Rehabilitation Hospital in Chicago. We’re up on the roof where she’s showing me landscape renderings of how the surrounding area will look once the planting begins. Stone paths, fountains, flower gardens and shrubs.
It’ll look beautiful. And it’ll probably cool things down up here. But Koverman
says this is for the patients who are learning to be mobile after disabling injuries. The hospital hopes that patients in rehabilitation will find the rooftop garden more pleasant and helpful than institutional tile floors and plastic obstacles as they learn to
manuever…


“You know, so, are patients more able to maneuver their wheelchairs in the community? Are patients able to use their hands better so they can cook better at home? Are patients able to stay out of the nursing home and go to their home? So, if we can get any kind of
those outcomes, then it’s a huge success.”


It might be more interested in the patients, but the hospital will still be helping Chicago reduce its heat island effect.


There aren’t very many of these projects in the city, so it’s hard to say whether the rooftop gardens could cool things down all that much. But Environment Commissioner Marcia Jiminez says all you have to do is go up on the roof on a hot day. City Hall sits right next to the County Building. In fact they look like the same building. But not from the roof. Only one side is garden.


“In last summer in 2001 on the hottest day, while it was about a hundred degrees on the city hall side, it was 165 on the opposite end of the building where’s there’s a blacktop roof.”


Even if you’re not interested in planting a garden on your roof, the city still requires some effort to cool things down. City ordinance calls for light colored material when a roof is replaced. And parking lots have to plant some trees before they can get a permit to resurface. Rooftop gardens aren’t mandated… but city officials say they’re learning first
hand that it’s a much better use of space in the city.


For the Great Lakes Radio Consortium, this is Lester Graham.
