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

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

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

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

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

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

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

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

(sound of kids playing outdoors)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Asian Carp Barrier Not Enough?

The U.S. Army Corps of Engineers is building a nine million dollar electric barrier to keep Asian carp out of the Great Lakes. But now the Corps is warning the fence in Romeoville, Illinois, might not be enough. The Great Lakes Radio Consortium’s Lynette Kalsnes reports:

The U.S. Army Corps of Engineers is building a nine million dollar electric barrier to keep Asian carp out of the Great Lakes. But now the Corps is warning the fence in Romeoville, Illinois, might not be enough. The Great Lakes Radio Consortium’s Lynette Kalsnes reports:


The Army Corps is building the electric barrier in the Chicago Sanitary & Ship Canal. But the Des Plaines River runs near the canal, and it often floods in the spring. Chuck Shea is the project manager for the Army Corps of Engineers. He says they might need to build a flood wall or levee so high waters can’t sweep fish past the new barrier.


“It’s possible that water from the Des Plaines River could run into the Chicago Sanitary and Ship Canal. And if it was a large enough flood and there were fish in the right place, they might be able to use that as a pathway to enter the Chicago Sanitary and Ship Canal.”


Shea says while this possibility is unlikely, it still will be an important issue to study down the road. He says the more pressing concern is that an existing temporary barrier could wear out before construction on the permanent barrier is finished.


Asian carp have been spotted about twenty miles downstream from the electric fence. The giant fish are considered a threat to sport and commercial fishing. Shea says state officials are working to find money for the last phase of the electric barrier project.

Lobbying for a Second Carp Barrier

A new barrier is being constructed to prevent the Asian carp
from getting into the Great Lakes. But this year, a Congresswoman
will seek money to keep an existing barrier in operation, as well. The

A new barrier is being constructed to prevent the Asian carp
from getting into the Great Lakes. But this year, a Congresswoman
will seek money to keep an existing barrier in operation, as well. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


The permanent underwater electronic barrier that’s being built in a canal near
Chicago is close to a temporary barrier that’s wearing out. But Illinois Republican
Judy Biggert
contends the new electronic fence will not be enough to keep out the voracious
invasive species
known as the Asian carp.


“Now I wish that I could say that with the construction of this permanent barrier
that our work
would be finished and the carp would never again threaten the Great Lakes, but I
cannot.”


Biggert wants to make the temporary barrier permanent, too. She also wants to make
sure there’s
federal money to operate and maintain both underwater fences over the long term.
So, Biggert is
seeking co-sponsors for a barrier bill that she says she plans to introduce early
this session of
Congress.


Her aides say she may also try to get the several million dollars needed for the
project put in the
budget for the Army Corps of Engineers. But many new domestic spending proposals
could face
a tough time in Congress, if conservatives try to reduce the federal budget deficit.

Smaller Fish After Alewife Die-Off

This past year, the size of salmon in some Great Lakes is getting smaller because
their main food
source is dying off in some areas of the lakes. The Great Lakes Radio Consortium’s
Lester
Graham reports:


In the 1960’s, fish and game officials introduced Pacific salmon such as chinook,
coho and
steelhead to control the invasive species alewife. That’s a small fish that moved
in from the
Atlantic. The salmon are popular fishing. But since the alewives are not native…
they’re
especially susceptible to quick weather changes. And fisheries managers suspect
competition
with zebra mussels for food also affects alewives. Recently, alewife populations
have crashed in
some places. Jim Dexter is with the Michigan Department of Natural Resources…


“The primary reason that there are not alewives in Lake Huron and you get
fluctuations in Lake
Michigan is related more to the climate. You know, now, zebra mussels are tied into
that, into the
equation at some point but not probably to the affect that the climate is having on
those.”


So, without as many alewives, salmon don’t have as much to eat… and they’re smaller
than usual.
Fisheries managers say the effect is probably temporary.

Congress Approves Asian Carp Barrier Funding

The U.S. House and Senate recently passed a bill that will help keep Asian carp out of the Great Lakes. As the Great Lakes Radio Consortium Celeste Headlee reports, the federal government will contribute nearly two and a half million dollars to help repel the fish:


Asian carp are huge, often growing to be four feet long and weighing 80 pounds. They are also extremely prolific and voracious. Most Asian carp consume up to 40 percent of their body weight every day. There is currently an electric fish barrier strung across the bottom of the Chicago Sanitary and Ship Canal to keep the fish out of the Great Lakes. The barrier creates an underwater field of electricity that repels the carp.


Andy Buchsbaum is the director of the National Wildlife Federation’s Great Lakes Office. He says the current barrier is temporary and due to fail next year.


“Today the Great Lakes really dodged a bullet. Right now, the carp are poised 20 miles away from the failing barrier, which is just downstream from Lake Michigan. And if that barrier fails, then essentially the Great Lakes as we know them are over.”


The U.S. House and Senate passed a bill that will supply 75 percent of the funds for building a new barrier. The Great Lakes governors have agreed to supply the rest of the money. President Bush has said he will sign the bill when it reaches his desk. Buchsbaum says the new barrier can be completed within 60 to 90 days.

Officials from a joint U.S./Canada Commission that monitors the health
of the Great Lakes is asking states and provinces in the region for
help. The International Joint Commission wants the governments to chip
in money to make sure that Asian carp don’t invade the Great Lakes and
decimate the fishing industry. The Great Lakes Radio Consortium’s Bill
Cohen reports:


A temporary experimental electronic barrier in the Chicago Ship and
Sanitary Canal is the only thing keeping Asian Carp from swimming into
Lake Michigan. That’s why the federal government and Illinois have
allocated 6.7 million dollars to build a new permanent fence.


But now, the builders say they need an extra 1.8 million dollars to complete
the work. That’s why the International Joint Commission is asking all the
states and provinces that have a stake in the dilemma to come up with
that cash. John Nevin is a policy advisor for the IJC. He says if the
older barrier fails or the new one doesn’t work right, the carp will
wreak havoc with the Great Lakes:


“What they do is they swim along with mouths wide open and they filter
feed. They eat all the plankton and all the little stuff that little fish eat,
so they would potentially rob all the other fish in the lake of their food.”


Ohio’s Governor Bob Taft heads the Council of Great Lakes Governors.
He’s seeking input from other governors so he can issue a response soon
to the plea for money.
