Some of the world’s most intricate
architecture is not always constructed by
humans. Sometimes the most skilled architectural
wonders are designed by nature. Gretchen Cuda reports on an exhibit that celebrates
birds’ nests:

Judith McMillan didn’t find her inspiration in tree branches. She found it in the
basement of the museum where she works. She was rummaging through drawers
there when she came across a hundred-year-old collection of bird nests.

“This Museum must have 10 cabinets full of bird’s nests.”

She was fascinated and immediately knew she had a new subject for her art.

McMillan is a photographer who has been volunteering at the Cleveland Museum of
Natural history for 20 years. In her latest exhibit, titled “Nesting”, she captures some
of natures most inspiring, and often overlooked architecture – the nests of birds.

(sound of exhibit crowd)

“I was looking for nests that were different from each other so that you could see that
these birds were little architects. And there were so many different kinds of materials
used – and then the eggs could be so different. Some with little tiny speckles, some
with different colors some with little calligraphic streaks around them, so it was that
variety that I wanted to capture.”

All the photographs are in black and white – because she really wanted people to
concentrate on the architecture without being seduced by the color. She’s fascinated
by the way different birds chose very specific materials to work with – everything
from marsh reeds, grape vine, or little knotty twigs – like this one.

“This is a vermillion flycatcher – it’s almost like it’s made of pick up sticks in the way
their pushed together.”

And to emphasize the diversity of structures birds can create she shows me an
Orioles nest that’s five inches deep and formerly hung like a basket from a tree.

“I actually had to shine a flashlight down in it when I was taking the photograph in
order to get the eggs to show up.”

Most of the nests and eggs were collected around the turn of the 20th century by
amateur naturalists who never thought twice about disturbing the natural wildlife.

But the practice eventually fell out of fashion as people became more
environmentally conscious and large nest and egg collections were often turned over
to museums – explains Andy Jones the museum’s ornithologist.

“People whose grandfathers were dealing with eggs as a hobby, well their
grandfathers are passing away and so they contact their local university or natural
history museum, and say, ‘hey do you want these?’”

Those specimens were originally collected just because they were pretty. These
days, they’re still beautiful, but they also serve a scientific purpose. Scientists can
look at things such as the thickness of the shells, or the type and number of birds
found in a specific location and tell a lot about the birds. They can see where birds
used to live and how far their territories reached. They can even tell if a bird that’s
extinct now once lived in an area.

Judith McMillan hopes her photographs will not only show how beautiful the birds’
handiwork was, but will also inspire people to do something about saving the birds
that are still here.

“I didn’t understand until I started using a camera myself how you can isolate
something and make people look at it differently–And I hope through my
photographs I’m getting people to take a fresh look at things. It’s hard to have an
appreciation of nature unless you really look at it and start to really care about it.”

Recent surveys have found that many songbirds are disappearing. If people don’t
start caring, those photographs and drawers full of nests might become the only
reminders of many more species that go extinct.

The Dark Side of Bright Lights

  • Most of us are using 125-year-old technology to light our homes. 95-percent of the energy used by a light bulb is heat. Only five-percent actually is used to produce light.

Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient… and the trend in home lighting is moving toward using more energy… not less. As part of the series, “Your Choice; Your Planet,” the Great Lakes Radio Consortium’s Lester Graham takes a look at light bulbs… and starts at the beginning:

Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient, and the trend in home lighting is moving toward using more energy, not less. The Great Lakes Radio Consortium’s Lester Graham takes a look at light bulbs and starts at the beginning:


We’re getting a behind the scenes look at a pretty significant historical artifact. Marc Gruether is pulling back a plastic tarpaulin that covers a row of file cabinets.


Gruether: “We are in one of the storage areas in the Henry Ford Museum. And drawer eleven has this light bulb in it which I will very carefully remove. It’s certainly one of the oldest Edison light bulbs that’s in existence. This is one of the lamps that was used in the December 1879 demonstration at Menlo Park.”


Graham: “Now, looking at it, I can see that it’s got that kind of bulbous shape, I can see the filament, I mean, I would recognize this easily as a light bulb.”


Gruether: ““Absolutely. It’s a recognizable light bulb. You’re exactly right. That all looks forward to the kind of lamp forms that became common and that we’d recognize today.”


And that’s not all that’s the same. Just like the first light bulbs, the incandescent bulbs most of us use in our homes today, waste energy. 95% of the energy used is expended in heat. Only five-percent actually makes light. That means everytime you switch on the light – if it’s an incadescent bulb – you’re wasting 95% of the electricity your paying for. In our homes, not much has changed in the last hundred years or so. But in commercial buildings, things have changed a lot.


Commercial builders and industrial architects learned a long time ago that energy efficiency is important. Most of the new office building and factories built today use passive sunlight and high-efficiency lighting that not only saves energy but uses the right spectrum of light to get the best output from their employees.


Moji Navvab teaches about light in architecture at the University of Michigan. He says you can learn a lot about good energy efficient light too. He says with the wide variety of fluorescent, LED, and spot lighting, you can get the right kind of light for whatever you’re doing and use a lot less electricity compared to a house lit only by traditional incandescent bulbs. It’s about using the right light for the right place. Navvab says, really, it’s pretty simple and you can get a lot of information about proper lighting on the Internet.


“If you really are focusing on healthy lighting or you want to save energy, if you go search on the web right away, you can get the information and then you can go to your local stores and they can match it for you.”


But at the local store, most of the time buyers are not very well-informed at all.


Beverly Slack is a salesperson at Kendall Lighting in Okemos, Michigan. She says unless they ask, she doesn’t push energy efficient lighting. And when she does mention fluorescent lighting, which uses about one-fourth the energy that incadescent bulbs use, customers grimace.


“Right. But, they don’t realize the difference in the fluorescent lamps, how they’ve changed, how the different colors have changed in the fluorescents. They’re still thinking of the old standard cool white so, people don’t want them because of that fact.”


Slack says what customers really want is dramatic lighting, and lots of it. They want trendy, recessed lights and track lights that often use extremely hot burning bulbs in a way that’s interesting, but not often very useful.


“They want decorative, decorative, decorative. I mean, it’s amazing. Because I can just see their light bills going sky high.”


Slack says the trend in home lighting in recent years has been just the opposite of commercial lighting. At home, people are using more light, more fixtures, and less energy efficient bulbs. With the trend in new houses being larger, requiring more lights, and homeowners wanting decorative lighting to show off their big new houses, conservation at home is often just being ignored.


It’s no longer about turning off the light when you leave the room, it’s about lighting up the showplace. And as long as the power bill is lower than the mortgage, it’ll probably stay that way.

Bigger Homes, Better Living?

  • American houses are getting bigger and bigger, but some architects question whether more square footage leads to a happier life. Photo by Lester Graham.

Although family size is growing smaller in the U.S., house sizes are growing larger. The square footage of a home built in the 1950’s seems tiny compared to the houses typically built in the suburbs today. The Great Lakes Radio Consortium’s Lester Graham looks at the trend of ever-larger houses:

Although family size is growing smaller in the U.S., house sizes are growing larger. The square
footage of a home built in the 1950’s seems tiny compared to the houses typically built in the
suburbs today. The Great Lakes Radio Consortium’s Lester Graham looks at the trend of ever-
larger houses:


There’s no one answer as to why we’re building bigger houses. For some people, it’s a matter of
investing. Housing prices continue to rise and bigger houses sell well. People trade up. But…
for some homebuyers, it’s more than that. It’s a statement.


Lynn Egbert is the CEO of the Michigan Association of Home Builders.


“A lot of that could be a status symbol. Move out of the city; move into a rural-like area because
‘I’ve made it,’ because ‘This is my dream.’ It used to be people would move up, sell their homes
every seven to ten years. That’s changed now and the sale of homes is now three to five years.
You build up the equity in a new home or an existing home, you have the opportunity to build or
move into something else later. It is an investment.”


Investing in a house only explains some of the reason houses are getting larger. Another reason is
government. Local governments are zoning residential areas into large lot subdivisions. Egbert
says that means the builder has to build a big house, just to recoup the cost of the sizeable piece
of land.


“That is a preclusion, a prohibition against Smart Growth. When they have large lots sizes, it
absolutely dictates and mandates that anybody who moves in there is going to have a large
home.”


It’s an attempt by towns to keep out lower-income people who might build homes that lower the
property values of a neighborhood.


But there’s a demand for the bigger houses and it doesn’t seem to be letting up. So, cities and
towns zone for them, builders build them, and people buy them – bigger and bigger.


Linda Groat is a professor at the University of Michigan’s Taubman College of Architecture. She
says it’s not too surprising. People feel less connected to the community at large because they
move often, drive somewhere else to work, and see their home as a refuge. Home is where they
can relax and escape from the rest of the world.


“There may be, on the part of some people, a feeling of need to really make it more of a castle to
compensate for what feels more complicated or out of control in the larger world.”


We feel we need private places that we can call our own. But there might be social costs to that
refuge. There’s often little interaction with neighbors and the rest of the community in which we
live. And Groat says even within the home all that space means family members don’t have to
bump into each other on the way to the bathroom. Groat says in the new large suburban homes,
sometimes derisively called McMansions, everyone can pursue their own activities in different
parts of the house.


“If you buy a McMansion and the master bedroom is off on one wing and or a different floor and
the kids are off in huge rooms way on the other side of the house, is that really going to foster
family connection?”


Some architects are becoming aware the scale of housing is beginning to leave smaller
families with a sense of emptiness, not a sense of space. Sarah Susanka is one of the leaders of a
movement to re-evaluate the concept of whether bigger is really better. The first question is
“Why?” Why are we building bigger houses?


“Well, there’s obviously a large market for larger and larger homes. And my belief is that people
are trying to fill a void in their lives with the only tool that we’ve really defined for ourselves in
this culture which is: more. More stuff. More square footage. You know, more indication that
we’ve arrived. All that stuff.”


But Susanka says there’s a longing underneath all that, an idea that there should be some better
quality of life that’s not being satisfied by just more square footage. She’s the author of a series
of books that started with one entitled “The Not So Big House.” She argues that people can use
the money they’d spend on additional square footage for space that’s rarely used for better
designed spaces where they actually live day-to-day. She says if the house is an investment, then
it should be an investment in quality craftsmanship and better living, not just more space.


“When something is thrown together and just is sort of raw space, but not much else, over time
it’s going to degenerate. And, the amount of square footage obviously has a direct correlation
with the amount of resources it takes to build it. So by making something that’s tailored to fit – in
other words, not with excess material – and then that’s going to last a long time that that should be
the first step in sustainable design.”


Graham: “So, you suspect a lot of these McMansions or starter-castles, as you call them, aren’t going to be
around very long?”


“Yeah, I think in the long haul those are not going to survive in the same way and are probably
not going to be looked after in the same way over time just because they’re not as well put
together and they don’t have the charm that’s going to make somebody want to look after them in
the future.”


Susanka says using resources for bigger houses is not environmentally friendly and does not
necessarily mean better living. She says builders and homebuyers should think about it this way:
build the space you need and do it well and do it in a way that somebody in the future will want to
preserve.

New Solar Panels a Flexible Energy Source?

A Canadian firm is gearing up to produce a cloth–like solar panel that will cost less than current
technologies. The Great Lakes Radio Consortium’s Lester Graham reports:


This is a photo-voltaic solar panel, but instead of being a sheet of silicon on glass, it’s tiny beads
of silicon between layers of aluminum foil and sealed in a plastic sheeting. It’s strong, light
weight, and flexible.


Ron Jutras is a company officer with Spheral Solar in Cambridge, Ontario:


“The primary difference between this particular solar panel and others that people are used to seeing
maybe on highway signs or potentially on buildings, is the fact that it is a pliable system, meaning
that it can be bent and wrapped around products.”


So the solar panels can be put on facades of buildings or draped over a roof. It also will come
in different colors, giving architects some flexibility. Because it uses much less silicon than
current technology, the price is expected to be quite a bit lower. The first commercial shipments of
the flexible solar panels are expected next year.
