TAMAQUA AREA SCHOOL DISTRICT
Tamaqua, Pa. • McClure Co.
Each building throughout the dis-
trict was retro;tted with new lighting
technology, and pneumatic controls
were replaced with DDC systems. ;e
all-electric high school was converted
to geothermal; the entire building is
served by a central variable-speed
water-to-water heat pump unit.
Annual energy savings are estimated
at 40%, with a 10% reduction in water
use. The project has been submitted
for ENERGY STAR certi;cation.

GROGAN’S SUDS-N-DUDS
Ronan, Mont. • Montana Radiant
The retrofit of this 5,000-sq.ft., four-
bay car wash and laundromat will save
50% in annual energy costs. A high-
e;ciency condensing boiler replaced
an old, atmospheric-;red copper-tube
boiler that was used to melt ice off
the ;oors of the car wash bays. ;ree
modulating tankless water heaters
replaced another larger atmospheric-
;red boiler that was used to heat water
for the car wash and laundromat. A
solar thermal system heats the water
whenever solar energy is available.

JARRELL RESIDENCE
West Tisbury, Mass. • Nelson
Mechanical Design, Inc.
;e use of a 5 k W wind turbine makes
this residence/yoga studio a net zero
project. Technologies applied include
geothermal, a radiant ;oor system, indi-
rect water heaters, and energy-saving
controls. A horizontal, six-ton direct
exchange geothermal ;eld was selected
to serve radiant space heating loads
through a buffer tank. Domestic hot
water is preheated using the geother-
mal heat pump through a ;at plate heat
exchanger with ;nal heat provided by a
plastic electric water heater.

COLLIN RESIDENCE
Southampton, Mass. • Orchard
Valley Heating & Cooling
This renovated home features a
five-ton horizontal geothermal loop
field with two split geothermal heat
pumps connected to two variable
speed air handlers, each with several
zones of conditioned air control. Each
air system features an air exchanger.
Second-stage heat is provided by a
modulating condensing boiler that
serves a 60-gal. indirect water heater,
both air handlers, and two zones of
radiant floor heat. A solar thermal
system augments the domestic hot
water demands.
