Solar-heated house nears completion
GREENVILLE, S.C. -
Construction of a medium
priced, three-bedroom
family dwelling heated with
solar energy, designed by
the U.S. Department of
Agriculture's Agricultural
Research Service (ARS), is
nearing completion.
The completely insulated
attic of the house serves as
the solar collector and a 12-
mch thick layer of crushed
rock beneath the floor of the
house serves as a heat
storage tank. The bouse is
conventional in other
respects.
The beating system is
simple in design. Two layers
of translucent fiberglass
replace conventional roofing
on the south roof slope and
transmit sunshine or solar
energy into the attic where it
is absorbed by a black
plywood floor. This heats the
air m the attic and the heated
air is circulated to heat the
house and the rocks beneath
the bouse. The heated rocks
can store a four-day supply
of heat to warm the house at
night and during cloudy or
rainy weather.

was designed at the ARS
Rural Housing Research
Unit, Clcmson, S.C., by
architect Harold F. Zomig.
It is part of the ARS effort to
lower the operating costs of
rural housing with a low
cost, low-maintenance
heating system using solar
radiation as the energy
source. Such a heating
system could be modified to
match the demands of other
geographic and climatic
areas.
Zomig predicts that at
least 75 percent of the house
heating load during the
coldest month in Greenville
can be supplied by solar
energy. To meet the small
need for extra heat during
the heating season a slightly
larger than nonnal hot water
heater is used as an
auxiliary heat source. Hot
water is automatically
pumped from the hot water
supply to heat exchanger in
the air distribution system
when and if the house has no
solar heat in the attic or in
storage.
The rocks that are used as
a heat storage tank in winter
can keep the house at a
to fewer acres harvested
than was expected at that
time.
U.S. fall potato production
was estimated at 271.9
million cwt., and is one
percent above last month but
6 percent below the 1974
record harvest.
pleasant daytime tem
perature during the warm
months. This is achieved by
bypassing the heat from the
solar collector and allowing
the rocks to cool at night.
Helio-Thermics, Inc.,
builders of the house is
cooperating with ARS in the
project. The Greenville firm
developed the solid-state
electronic controller which
operates the house’s energy
conserving system.
The ARS Rural Housing
Research Unit will monitor
the performance of the
prototype house through four
seasons starting this winter,
according to Mr. Zomig.
Performance during the
year will be measured while
the house is occupied.
Although designed by ARS
and built to ARS
specifications, construction

EVERY $l.OO IN AUREOMYCIN
YOU PUT INTO YOUR HENS
RETURNS $l3 IN EXTRA EGGS
The Aureomycin Week-a-Month Layer
program helps you get maximum egg
production on a minimum of feed.
For an investment of per hen per
year in AUREOMYCIN® chlortetra
cycline, experience shows you can expect
an extra dozen eggs per bird—or an extra
return of $4OO per f,OOO birds (with eggs
at 40^/doz.).
This figures out to a return of $l3
for every $l.OO in AUREOMYCIN you
put into your layers.
The program is easy to manage. Just
feed hens 100 grams of AUREOMYCIN
chlortetracychne per ton of feed for one
week each month as long as birds are in
production.
Trials show AUREOMYCIN also
saves one-quarter pound of feed for every
dozen eggs produced.
This program is equally effective for
broiler breeders. Based on commercial
trials, 3<(. in AUREOMYCIN per breeding
hen produces six extra chicks per breeder
or a total of $450 extra return a year
from every 1,000 birds (with chicks at
7.5*).

EVERY $l.OO IN AUREOMYCIN

RETURNS $2.76 IN EXTRA MEAT
The Aureomycin First-Pound-of-Feed
starter program helps you get
maximum gains on a minimum of feed.
The program is easy to manage. Just feed
chicks 200 grams of AUREOMYCIN®
chlortetracycline per ton in the first pound
of feed (with L 25% sodium sulfate and
0.8% calcium).
This program, which provides chicks
with high levels of AUREOMYCIN in the
cntical first three weeks, helps reduce
mortality and aids in the prevention of
synovitis.
Thais with over 14 million broilers show
that weight improvements and feed savings
produce an extra return of $8.28 per 1,000
birds (with feed at 6tf/lb. and broilers at
IBtf/lb. live weight).
This figures out to a return of $2.76 for
every $lOO in AUREOMYCIN you add to
your feed. Less than l/3e per bird is all it
takes to provide AUREOMYCIN in the
first pound of feed
