You might have heard the Sears Tower
in Chicago is now called the Willis
Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental
facelift that could cut eighty-percent
of its energy use. You might wonder:
what could a homeowner learn from what
the Willis Tower is doing? Shawn Allee thought it wouldn’t hurt to ask,
and went on a tour for the answer:

You might have heard the Sears Tower
in Chicago is now called the Willis
Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental
facelift that could cut eighty-percent
of its energy use. You might wonder:
what could a homeowner learn from what
the Willis Tower is doing? Shawn Allee thought it wouldn’t hurt to ask,
and went on a tour for the answer:

One of the co-owners of the Willis Tower is John Huston. He says there’s plenty for
people to learn from the tower’s green rehab plans. To start – we’re at the base of the
tower, and we’re craning our necks up.

“We’re facing north. We’re looking at a hundred and ten floors, so that’s 16
thousand windows in total.”

Huston says those windows are the old single-paned kind common in 1974 – back
when the Willis Tower was finished. In the summer, the windows let heat in, and
during the winter, they let heat escape. And that black metal you see in photos? It
does the same thing.

Huston: “The building is clad in aluminum if you went outside in the winter, you
certainly wouldn’t want to wear an aluminum ski jacket.”

Allee: “You’d freeze.”

Huston: “Exactly.”

So, Huston says the first thing they’re gonna do at the Willis Tower is what he calls
“tighten the building’s envelope.” It means insulating the building from the outer
walls and replacing the windows – all sixteen thousand of ’em.

“It’s an incredible job. That’s what we have to change in order to conserve the 80%
of energy that we anticipate doing.”

Huston says energy consultants pretty much give homeowners the same energy
advice. He says, the nice thing is, once you do that it’s easier to figure out what’s
next.

“Watch your step.”

Huston takes me into the guts of the Willis Tower. This is where it’s heated and
cooled. He says since the building’s gonna waste less energy, he won’t need such
powerful equipment.

Huston: “A lot of what’s in here will disappear or shrink.”

Allee: “So what is this?”

Huston: “This is an electric boiler. It provides hot water to heat the building. Each
one of these consumes enough electricity to heat and light a town of 6,000 people.
We have eight of these throughout the building. It’s not just the boilers. in this
section behind us, you have all the pumps that move hot water throughout the
building. Each one of those pumps is hooked to an electric motor, and 50% of them
can be eliminated.”

Huston says the take-away here is that once a building requires less energy to heat
and cool it, the other savings can kind of cascade from that.

But there’s another lesson homeowners can learn from the Willis Tower’s green
rehab.

The architecture firm that planned this project is called Smith and Gill. Gordan
Gill tells me, their work was made easier by the fact the Willis Tower owners keep
records of their power use.

“When you’re designing something new, you’re predicting the performance of
something. Here, you can actually test it, since you have records of how much
energy was spent, how much energy was used – you know where you stand, exactly.
And so now, you can do mock-ups and tests and things like that.”

Gill says that’s a good reason for homeowners to hold onto their power and heating
bills, too. He says if you’re confident in your actual costs and likely savings, you’re
more likely to follow through with your rehab project.

“And that’s important because you’re avoiding the obsolescence of these buildings,
and I think that’s true from everything like Willis to people’s houses.”

Big cities have skyscrapers, smelly subway stations,
and people from all over the world. In our
occasional series about people’s connections to the
environment, Kyle Norris talks with one big city
resident who says that the people and places of New
York City connect her to the world:


Audra Brecher wears her chestnut hair in a Louise
Brooks bob. Actually, she’s a dead ringer for Louise Brooks,
that silent film movie star. She’s stylish
and snazzy.


Audra lives in Manhattan. Her apartment is above a
pizza parlor on a bustling avenue. She says in the
evenings, she hears blaring taxi horns and the thumping
techno music from the clubs on her block. But she
loves everything about the city: its sounds,
its architecture, and its people.


I once asked her if she ever missed nature. She said,
“The city lights are my stars.”


“Yeah, I don’t feel as if I’m missing anything. I don’t
feel maybe such a romantic feeling about stars, the
night sky. I feel maybe the same excitement when I
see the city lights and when I walk across Lexington
and I look north and I see the Chrysler Building lit
up and those beautiful, starry chevrons of the
Chrysler Building. I think maybe the feeling I have
looking at that, is what other people feel when they
look at the night sky.”


So here’s the deal. When I think of someone connected
to nature I picture a state park ranger. I picture a crunchy-
granola type. I do not think of someone who wears
fashionable clothes and wines and dines in the city. I
do not think of Audra. But Audra says she has a
better connection to the natural world than people in the
suburbs:


“I go to the Union Square market on Saturday and I
buy varieties of apple that have come from the
Hudson River Valley and I know my parents, who
live in the suburbs in Florida, they go to the grocery store
where they buy everything pre-packaged and already
cut up fruit. I feel like my experience is actually closer to
nature even though I’m in heart of Manhattan.”


Audra works in an architecture firm. She’s a historic
preservationist, and she’s studied architecture all over the
world. But she grew up in the Florida suburbs. And
what she saw there – the sprawl and development –
seemed wrong to her:


“What led me to do what I do is noticing how
unhappy I was with a suburban existence. Having to
get in car to drive somewhere, or looking at
expanses of parking lot in strip centers and
subdivisions with gated communities that are named after
the natural feature they replace. Like ‘Eagle’s Nest.'”


Those new developments seem wasteful to her. She
likes the idea of re-using materials. And this
connects her to nature. At her job, she’s always in
close contact with old buildings and old materials:


“Yeah, I love the materiality of them. I mean, I love
an old brick from 120 years ago. I love the building
materials and the craftsmanship from that time. I
love the idea of taking something that has been cast
aside and might not be used and giving it a new
purpose, giving it a new vitality. Taking a building that
somebody has abandoned and giving it a new life.
To me, that’s the ultimate recycling.”


Audra says although she’s not walking through the
forest and communing with nature, she feels
ecologically responsible in different ways. She either walks or takes public transportation to get someplace. She never drives a car.


“I’m not asking so much of the world in terms of
water and energy and resources and I feel like when
live in dense environment you are allowing for those
things to remain protected and safe. And pristine. So
I feel like a responsible citizen living in Manhattan
in many ways.”


This stylish city-slicker may not be the person
who pops in your head when you think of someone who’s connected to nature. But Audra’s
deeply connected to the world around her in her own way. She’s also aware of how we can use natural
resources in better ways.
