Energy-efficiency renovation plans
to continue for university buildings
By Leslie Bocllstorff
Despite prolonged cold weather this
winter, utility costs for UNL buildings did
not exceed budgeted amounts, said the
physical plant director. The budget is based
on a more severe winter, said Harley
Schrader.
In spite of the good report, energy-efficiency
renovation plans continue campus
wide. Renovations improving the energy effi
ciency of the Nebraska Union should be
completed by the end of this summer, said
Daryl Swanson, director of the Nebraska
Union, Tuesday.
Bids for the project will be let at the
end of this month or the beginning of next
month, Swanson said, and work on the
project should begin in June. The cost of
the project is estimated at $297,900, of
which SI. 37,950 is a federal grant. The NU
Board of Regents has approved the use of
$160,000 from bond reserves for the rest
of the project's funding.
The savings created by the improve
ments should pay for the project in less
than seven years, Swanson said. Currently,
utilities in the Nebraska and East Unions
cost about $300,000 a year, Swanson said.
The energy costs are so high because the un
ions are open more hours a week than any
other campus building. Also, there is a lot
of traffic moving in and out of the build
ing, which increases energy use, Swanson
said.
There arc three major aspects of the Ne
braska Union renovation project, Swanson
said. The first involves replacing all the old
windows in the original part of the build
ing the south third of the building.
Swanson said the windows are being re
placed for aesthetic as well as energy-conscious
reasons. The deteriorating windows
marr the building's appearance and cause
the loss of heated or air-conditioned air,
Swanson said.
New windows
The window system on the north side of
the building will be improved as the second
aspect of the project, he said. Fifty per
cent of the glass on the second floor will
be replaced by blank panels, Swanson said.
The panels will have glass on the exterior,
to retain the appearance of the building.
The rest of the glass will be double-paned,
he said. Both window replacement projects
will cost $183,000.
The third part of the project will be re
placing the fume hoods in the kitchen,
Swanson said. The present hoods were in
stalled in 1959. The hoods let heated or air
conditioned air directly outside, causing
energy waste, Swanson said. The new
hoods would have both a supply and ex
haust function, allowing the recirculation
of the filtered air. Replacement of the
hoods will cost $68,500.
Insulation
An additional part of the project invol
ves insulating the attic of the original buil
ding, costing $47,400.
A fourth part in renovating the unions'
heating and cooling air system would cost
$307,000 and has been delayed.
The union renovations are part of a
campus-wide effort to increase the efficien
cy of university buildings. Schrader said
the list of needed work to improve, energy
efficiency far exceeds the amount of dol
lars available for sucli projects.
The physical plant has completed most
of the "quick-fix and cheapic" projects like
turning down thermostats and switching
from incandescent lighting to fluorescent
lighting, Schrader said. What remains are
the "real" projects - replacing single
glazed, double-hung windows that "leak
like a sieve," insulating walls and roofs and
improving the forced-air systems in many
buildings.
Available funds
"We're doing the work as the money be
comes available," Schrader said. Applica
tions for federal grants to help fund such
building modifications have been made, he
said.
The physical plant anticipates spending
$80,000 to $90,000 on insulating and re
building the roof on Baker Hall on Hast
Campus. Replacing windows in Burnett
Hall will cost about $125,000, Schrader
said.
Insulation in a small building would cost
$10,000 to $15,000, he said, while insula
ting a larger building may cost as much as
$40,000.
The physical plant could easily spend $1
million on renovating buildings to increase
their energy efficiency, Schrader said. Be
cause spending that amount isn't high on
the Nebraska Legislature's or the UNL ad
ministration's priority lists the physical
plant has applied for federal matching
grants through the state energy office, and
is making improvements as money becomes
available.
Last year, the physical plant had $4.5
million for utilities, Schrader said. This
amount included 150 academic and general
purpose buildings on both campuses. It
did not include utility costs for residence
halls, the Bob Devaney Sports Centei or
the Nebraska Center, which designate uti
lity funds in their own budgets.
Residence halls
Energy conservation measures saved
each residence hall occupant about $40 a
year in room and board, Housing Director
Douglas Zatechka said.
For the fiscal year beginning July 1,
$1.1 million is designated for energy costs
for the 1 1 residence halls, he said. This is
on increase from the $780,000 budgeted
two years ago, he said.
Attempts to conserve energy in the re
sidence halls include insulating roofs, ex
tending the use of water used to steam heat
the buildings (using it until it cools to 110
degrees instead of the 170 degree tempera
ture at which it was previously piped back
to the physical plant and saving approxi
mately $25,000 to $40,000 for each hall),
installing reducers in showerheads so they
use 1.9 to 2.5 gallons of water per minute
instead of the previous 8 gallons a minute,
and changing lights from incandescent to
fluorescent. The caulking of most of the
residence halls has also been completed,
Zatechka said. Thermostats have been turn
ed down to 68 to 70 degrees, he said.
Professor says primitive Indians
viewed as hindrance to whites
Tribes of primitive South American
Indians, who until recently had no expo
sure with the outside world, are finding
themselves in the same cowboys and In
dians situation that took place in the Uni
ted States, said Raymond Hames, UNL
professor of anthropology.
Hames' lecture and accompanying film
Tuesday was sponsored by the Inter
national Educational Services, which an
nually presents a Global Affairs Program.
Hames spent 18 months studying primi
tive Indian tribes in Venezuela.
The Brazilian government, Hames said,
in an effort to develop the Amazon Basin
in the nation's interior, is exploiting the
land without regard for the Indians living
there.
Brazil has a weak economy, he said, so
it encourages multinational corporations to
invest and develop the Amazon Basin.
Brazil's government offers the multi
national corporations tax incentives and
sells them large blocks of land very cheap
ly - as low as 18 cents an acre, Hames said.
The government, burdened with over
crowding on coastal areas, is trying to
get peasants to migrate to the Amazon
Basin to begin a new economic life.
This is also true in Columbia and Vene
zuela, where tribes of Indians are compet
ing with cattle ranchers for the land.
The Indians are viewed by the white set
tlers as animals and as a hindrance to devel
opment, Hames said.
historically, the Indians could do little
to prevent the exploitation ot their lands
because die government exercises little
power in undeveloped areas.
Fortunately, Hames said, efforts made
by Indian groups who are starting to or
ganize politically and international support
organizations are beginning to help the In
dians have some voice, however small,
concerning their fate.
The World Bank and the International
Monetary Fund now require countries to
submit an environmental and social impact
report before loans aiding development are
approved, he said.
