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.

A new study looked at off-the-shelf
shower curtains and came up with some disturbing
findings. The Center for Health, Environment
and Justice studied polyvinyl chloride plastic
shower curtains and found that PVC shower
curtains can release as many as 108 toxic
chemicals. Lester Graham talked with Sarah
Burkhalter with the environmental journalism
site: grist.org. He asked just how
much of a concern these PVC shower curtains
are:

Sarah Burkhalter: “It depends. This group – The Center for Health, Environment, and Justice –
tested five shower curtains, and their claim is that new-shower-curtain-smell is up to 108 nasty
chemicals that have been added during processing. At the same time, you know, there are
chemicals in everything. So, to an extent, you just have to choose your battles. Shower curtains
have become the emergency-du-jour, if you will. But, there is plenty else to worry about if you
already have a shower curtain. It’s not an emergency.”

Lester Graham: “Now we should point out that these shower curtains are not special shower
curtains. These were bought at Bed Bath and Beyond, and Kmart, and Sears, and Target, and
Wal-Mart. And I don’t even know what I would replace my shower curtain with. Got any ideas
about that?”

Burkhalter: “Sure. Well, the thing about these shower curtains, you know, it’s not even the shower
curtains themselves. It is the plastic they’re made of. And that is plastic #3. Its poly-vinyl chloride,
or PVC, or you may sometimes you may just see it as vinyl. And at grist.org, our advice columnist
always says, ‘no vinyl, that’s final’. That’s her tagline. She says, ‘no PVC for me’. That’s her other
way to remember it. Really, as much as you can avoid this plastic #3. Which, is difficult to avoid.
It’s in toys, and hospital tubing, and jars, and pill bottles. But as much as you can avoid this, is for
the benefit, certainly. As far as shower curtains go, there are a lot of alternatives. You can always
go for a door instead of a curtain. When our advice columnist, Umbra, wrote about this very issue
in 2006, she recommended polyester shower curtains. They also make organic cotton, and nylon.
There’s a different plastic, its PVC-free, its called ethylene vinyl-acetate, or EVA, so if you look for
EVA plastic shower curtains, those are a good alternative. Or, you could always take up
exhibitionism.”

Graham: (laughs) “Well, how hard are these things to find – these other, non-PVC shower
curtains?”

Burkhalter: “They’re going to get easier and easier to find as time goes by. Actually, IKEA phased
out PVC shower curtains over a decade ago. Sears, Kmart, Wal-Mart, and Target are all in the
midst of phasing out PVC. And, actually, Target had a goal for this spring, I think they said 88% of
their shower curtains now don’t contain PVC. So, if you look at the labels, and try to avoid things
that say PVC, you should be able to find alternatives, even in these big box stores.”

Graham: “So, what do you have hanging in your shower?”

Burkhalter: “Well, I have to say that I took a shower this morning, and it is a plastic shower curtain.
But, you know, I’ve had it for a couple of years, and the Center for Health, Environment, and
Justice, when they tested, they found that some of these chemicals hung-out for a few weeks, but
after a month or so, your shower curtain has probably done off-gassing all the chemicals that it’s
going to. So, if you’ve had your shower curtain for a couple of years, you know, really, instead of
trashing it, it’s probably best just to hold on to it. Don’t’ burn it – that is something that you really
don’t want to do with PVC. That’s kind of one of its great dangers, is that it releases dioxin, a nasty
chemical, when it’s burned. So, but as long as you’re not licking it regularly, you can probably hold
on to your old one.”

Graham: “I’ll avoid that. (laughs) Alright, thanks Sarah, thanks very much.”

Burkhalter: “Sure, thanks Lester.”
