Prefab parlor
The other side of the structure
functions as a utihty room. It
contains supplies, a water heater,
a vacuum pump, dual
refrigeration compressors and an
energy conversion system.
Hafer selected the Bally prefab
building for its insulating abilities
"Not only does it keep us warm,
but my plumbing lines don’t
freeze,” notes Hafer
On Christmas day, 1980, the wind
chill index in the Douglassville
area fell to -17°F Hafer reported a
67°F temperature in his parlor
with no heat to supplement that

“In the heat of summer we sneak
into our parlor to cool off,” Hafer
says with a chuckle
The Bally panels used to con
struct Hafer’s new parlor and milk
house are constructed of four in
ches of foamed-in-place urethane
between 22-gauge steel skins.
Bally urethane is one of the most
energy-conserving insulations
available With an insulating ef
ficiency rating, of "R” value, of 34,
it is more than twice as effective as
the same thickness of the best

Apart from the heat generated
by two refrigeration compressors
located against the parlor wall in a
corner of the utility room, Hafer
uses the animals’ respiration to
keep himself and his family
comfortable during milking Hot
air from the compressors is
exhausted into the milking parlor
through a grate measuring
34”x78”.
Hafer says while the initial cost
of a prefab building is slightly
higher than that of a comparable
block and masonry structure, the
savings in energy costs alone are
soon recouped

washed and milked in the parlor, and fed their grain based on

to buy and install additional in
sulation with a cmderblock
building, the cost for the Bally
building is almost the same,”
according to Hafer. “So why not
buy the best at the start 9 ”
Recently, a parked tractor ac
cidentially rolled into the building,
damaging some of the panels,
including the doorcap and a corner
section, which was badly buckled
Replacing the corner section, the
door and a window was ac
complished in just Wz hours.
“If we’d had a block building,
I’m sure the damage would have
been worse,” Hafer says. “But the
real problem would have been that
it takes too long to fix a building
like that. The cows have to be
taken care of, and there’s just no
end to the problems we might have
had if it had taken weeks to finish
the repairs.”

AIR PATTERN and MOVEMENT
This is the key to excellent ventilation
Twelve individual adjustable nozzles
control air direction up and down, the
length of throw and velocity The length of
throw is crucial in avoiding down drafts at
the walls The velocity ensures proper
mixing of air at the ceiling level, uniform
temperature and proper air motion at the
livestock or poultry level This air pattern

Bally panels are joined by steel
cam-action locks which are
foamed into the cores along edges
during fabrication. A simple hex
wrench is used to actuate the locks,
which are precisely positioned to
meet perfectly. When pulled
together, tongue-and-groove fit
tings on the panel edges mesh to
form tight seals, enhancing the
prefab’s insulation capability
Another device which helps
Hafer keep pace with rising fuel
and operating costs is an energy
converter. The small unit,
mounted on the prefab’s wall,
recycles heat generated by the
compressors to convert BTUs of
milk heat into BTUs of water heat.
The converter keeps the milk
house’s hot water at temperatures
between 120* and 160*F. without
using a bit of gas or electricity.
