Energy efficiency is on the mind
of a lot of homeowners. They’re
starting to question everything
about their homes, even the need
for air conditioning. Lester
Graham met with some homeowners
and an energy-efficiency expert
to talk about a different approach
to cooling a house:

For some people, air-conditioning just feels a little unnatural. I mean, it’s a refrigerated room, right?

There are older ways of cooling a house that are cheaper and use a lot less electricity.

Matthew Grocoff is with Greenovation TV. His website suggests all kinds of ways to make homes more green.

We met at a house in a tree-lined neighborhood of century-old homes in Ann Arbor, Michigan.

(sounds of house and stairs)

He wanted to show me an idea that’s like throwing open the windows and pulling in a cool summer breeze.

It’s called a whole house fan.

Grocoff: “We’re at the home of Jacinta Beehner and Thore Bergman. Thore actually installed this fan himself. It cost about $250 – about $9500 less than the quote that they got to install an air conditioning system in their house. And, this summer, they have not had to turn on their window units at all.”

Now Thore is not a carpenter. He’s a university researcher who studies monkey vocalizations. But, he decided he’d try to install the big fan in his ceiling on his own.

Bergman: “It was fairly easy. It took a couple hours. The tricky thing was – we have an older house that had layers of plaster and wood in the ceiling. So, cutting through that to make the hole took a little more work that it might in some houses. But it wasn’t too bad.”

Beehner: “I have to admit, I didn’t really believe that maybe he could install it himself. And yet, he did a great job. And I am the biggest fan of the whole house fan.”

Grocoff: “So, you’ve got the Beehner-Bergman fan club here. And this is interesting, because the goal, for most homeowners, is to get the house to a comfortable 72 degree temperature. And, it’s kind of strange that when it’s 65 degrees outside, and it’s 80 degrees inside your house, that we’re turning on an air conditioning unit when the air outside is actually colder than the air conditioning unit.”

Bergman: “One drawback is the noise. Which, we’ve gotten used to. We kind of like it for sleeping – it blocks some of the street noise. We’re standing right underneath it, and it’s kind of hard to talk.”

Beehner: “But, we also have a baby. So the whole house fan serves as white noise, which really helps us move around upstairs while he’s asleep.”

Grocoff: “Those people who are not looking for that white noise sound, like Jacinta and Thore are for their baby, they’re going to be able to get something that’s quieter, more efficient, more insulated, that’s going to be virtually silent, at the higher price points.”

There have been some surprises along the way.

Jacinta says, you have to keep in mind – anything in the night air will be drawn into the house.

Beehner: “One night, we actually did turn it on, and within about one minute, our entire house was filled with the smell of skunk.

Grocoff: “So, if you’ve got really good, deep skunk smell, you know the fan is working. Another possible drawback is, with the air, you’re bringing in any kind of dust, pollen, anything else like that.”

But, Grocoff says, overall, this big sorta-box fan in the ceiling really pulls the hot air out of the house and pulls the cool air from outdoors into the house.

Now, these fans don’t work everywhere.

If you live in an extremely humid area, or a region where it never really cools down at night or in the morning, it might not be a good fit.

But for areas that enjoy cooler mornings and evenings in the summer, Grocoff says this is a good alternative.

Grocoff: “With a whole house attic fan, you’re going to get the same comfort as you would with an air conditioning system. But, on a dollar-for-dollar basis, the cost for running an air conditioning system is 20 cents to 30 cents every hour that you have that turned on. For a whole house attic fan, you’re talking about a penny to a nickel an hour.”

There are all kinds of designs besides the big box fan types.

You can go to a home improvement store, your heating and cooling installer, or do some research online at greenovation.TV or just type in whole house fan in Google. You’ll find plenty of places wanting to sell you there version of a newly popular old idea.

If You Build It… Will They Really Come?

Right now it’s happening in Washington, D.C. as the capital city tries to lure a baseball team. It’s happening in New York where the city’s deciding whether to spend 600 million dollars on a new home for the Jets in Manhattan. The debate is over what the taxpayers get.

In cities across the nation, taxpayers are finding themselves facing the same dilemma:
cough up big bucks for a new sports stadium… or else. Right now it’s happening in
Washington, D.C. as the capital city tries to lure a baseball team. It’s happening in New
York where the city’s deciding whether to spend 600 million dollars on a new home for
the Jets in Manhattan. The debate is over what the taxpayers get. The Great Lakes Radio
Consortium’s Richard Paul takes a look at whether sports stadiums really can hit a
homerun for taxpayers:


It’s sort of funny when you think about it. The most hackneyed rationale you can think of
for building a ballpark is… it turns out… actually the primary motivation when cities sit
down to figure out whether to shell out for a stadium. You know what I’m talking
about…


(MOVIE CLIP – “FIELD OF DREAMS”: “If you build it they will come…”)


Just like in “Field of Dreams.” Put in a stadium. People will show up, see the game, eat
in the neighborhood, shop there, stay overnight in hotels, pay taxes on everything and
we’ll clean up!


(MOVIE CLIP – “FIELD OF DREAMS”: “They’ll pass over the money without even
thinking about it…”)


Here’s the thing though… it doesn’t work.


“In the vast majority of cases there was very little or no effect whatsoever on the local
economy.”


That’s economist Ron Utt. He’s talking about a study that looked at 48 different cities
that built stadiums from 1958 to 1989. Not only didn’t they improve things, he says in
some cases it even got worse.


“If you’re spending 250 million or 750 million or a billion dollars on something, that
means a whole bunch of other things that you’re not doing. Look at Veterans Stadium
and the Spectrum in South Philadelphia or the new state-of-the art Gateway Center in
Cleveland. The sponsors admitted that that created only half of the jobs that were
promised.”


But what about those numbers showing that stadiums bring the state money – all that
sales tax on tickets and hot dogs? Economists will tell you to look at it this way: If I
spend $100 taking my wife to a nice dinner in Napa Valley…


(sound of wine glasses clinking)


Or we spend $100 watching the Giants at Pac Bell Park…


(sound of ballpark and organ music)


…I’ve still only spent $100. The hundred dollars spent at the ballpark is not new money.
I just spent it one place instead of another.


In Washington right now, fans have been told they can keep the Washington Nationals, if
Major League Baseball gets a new stadium that the fans pay for. Washington is a place
was more professional activists, more advanced degrees and more lawyers than it has
restaurants, traffic lights or gas stations. And as a result, it’s practically impossible to get
anything big built. But the mayor’s trying. He wants the city to build a new stadium in
really awful part of town and use baseball as the lever to bring in economic activity. The
reaction so far? Turn on the local TV news…


NEWS REPORT – NEWS – CHANNEL 8
ANCHOR: “Baseball’s return to the District still isn’t sitting well with some folks. One
major issue is the proposal for a new stadium.”


ANGRY MAN GIVING A SPEECH: “Tell this mayor that his priorities are out of
order.”


Turns out that guy’s in the majority. A survey by The Washington Post shows
69% of the people in Washington don’t want city funds spent on a new baseball stadium.
We Americans weren’t always like this.


MOVIE CLIP – SAN FRANCISCO WORLD’S FAIR
ANNOUNCER: “You will want to see the Golden Gate international exposition again
and again in the time you have left to you…”


Today politicians need to couch this kind of spending in terms of economic development
because no one will support tax dollars for entertainment. But there was a time in
America when people were willing to squander multiple millions in public money for the
sake of a good time.


MOVIE CLIP – SAN FRANCISCO WORLD’S FAIR
ANNOUNCER: “Remember: Treasure Island – the world fair of the West closes forever
on September 29th.”


In 1939, in New York and San Francisco, and then again in New York in 1964. they
spent MILLIONS. And the purpose was never really clear. Here’s Robert Moses… the
man who made New York City what it is today… on the 1964 Fair.


REPORTER: “What is the overall purpose of the new Fair?”


MOSES: “Well, the overall stated purpose is education for brotherhood and brotherhood
through education.”


MOVIE CLIP – NEW YORK WORLD’S FAIR
ANNOUNCER: “Everyone is coming to the New York World’s Fair. Coming from the
four corners of the earth. And Five Corners, Idaho.”


Maybe those were simpler times. When people were a lot more willing to let rich men in
charge tell them what was right and wrong. Today, a politician looking to build himself a
monument is going to have to convince people it’s for their own good – and economic
development is the most popular selling point. Looking around these days – more often
than not – it seems voters are willing to rely on a quick fix. Taken together, that’s a
recipe for this kind of thing continuing. After all, when you’re a politician building a
legacy for yourself, a sports stadium is a lot sexier than filling pot holes or fixing school
roofs.
