History of Hunt Country Vineyards
42 Years of Thought
Award Winning Wine
Emphasis on Local
Building design for energy reduction
Sustainability is 1st thought
Geothermal for cost savings
Plans for wind and Solar

Geothermal as replacement for propane and oil
One main system for 4 buildings
Return on Investment Reliability of system Flexibility of Design
Vision
NYSERDA – AEEP R17 Grant – 75% funding
ESS – Design/engineering/support
BMI – Geothermal Drilling/Install
DEI – Installation, service
MG – Coordination/communication
Hunt Country – Initiative and willingness to say “YES!”
Players
ESS DESIGN Common Loop
Design “Node” based
distribution of Antifreeze
3 Heat Pump Banks, 6 Total Heat Pumps
Piping between buildings
Control Strategy Possibility of
Expansion
Plan
Process – The Source
Location of Wells – 8 Wells, 400’ deep
Drilled at rate of 6.5’/Min 1.25” HDPE, Thermal Grout Approximately 21 Tons of
Capacity Completed in just under 3
Days Average EWT is currently 46
Degrees
The Well Field serves a single GV Series Flow Center by Phoenix Energy which in turn serves 6 total water to water heat pumps scattered over an acre of land
Process – Source Distribution
Piping Size varied between 3” and 2” to reduce pressure drop and reduce pumping energy
Each “NODE” is served by zone valves
A call for heating/cooling opens a Valve
The flow center maintains the right pressure to provide the correct flow
Two 4 ton W/W Heat Pumps
Wilo VFD Pumps Storage Tank Control
Process – Tasting Building Mechanical
Building served by existing under floor Radiant
Addition of High Wall mounted Mulitaqua fan coils – 5 Total
Replaced 20 yr old boiler, 4 Mitsubishi Mini split Systems
Ability to Cool space with 75+ People – unable to do so with Air Source previously
Process – Tasting RoomDistribution of Energy
Space used as storage for Wine, Bottling Facility, Red Wine Fermentation Control
Two 4 Ton W/W Zone Valve for “on/off” Distributes to 2 air
handlers – IN TWO DIFFERENT BUILDINGS!
Domestic Hot Water for cleaning

We were asked a question during the installation process
“Can we heat our red wine to start Fermentation?”
Process – Production Facility
Radiant Slab Air Handler Domestic Hot
Water
Future Use will include Chiller Replacement
Process – Production Facility
NYSERDA Grant required M&V for release of Funds
Savings in First Year of Use = $12,000.00+ Savings in Second Year of Use =
$14,000.00+ Total Electric Consumption of Property was
actually reduced in 1st year and stayed the same for 2nd year.
Total Electric Cost in year 1 for property was $24,000.00. Year 2 was $30,000 for property for same KW usage but 23% hike in rates
Results
Spring of 2015 Brings the next Phase of Hunt Country Vineyards journey
100KW of PV will be installed to offset 80% of the properties usage
Next Step
Future is in this room
