FORT KNOX ENERGY INITIATIVES

UNCLASSIFIED3 of 38


CONTROL !!!!

• Meter all your consumption (Electric, gas, water ??)• Use the data from the meters to drive your decisions• Get to real time data for the critical items (15 minute)• Make sure you can control those big items real time

• Just like the utility company does with you, demand limiting

• The bottom line is you have to make decisions that effect the BILL !!• You can do this in such a way that you benefit the

environment as well as the bottom line.

Energy Saving Projects


UNCLASSIFIED7 of 36


Lighting Improvements

• Improve low lighting conditions while saving energy

• Provide on-demand lighting through use of occupancy sensors

• Harvest natural light when applicable

• Eliminate High Intensity Discharge (HID) lighting indoors


UNCLASSIFIED8 of 36


Infrared Heating

Infrared systems heat buildings in the same way the sun heats the earth

• Energy efficient (92%)

• Quick heat recovery

• Environmentally friendly

• Reduced heating costs

• Comfortable heat

• Focus heat on people and objects

• Eliminate inefficient boilers

** 110 buildings on post, typically high bay maintenance and storage

Insulation Upgrades

• Upgraded insulation in multiple types of buildings

– Spray foam

• Encapsulated crawl spaces improving energy efficiency and indoor air quality

• Decreases infiltration and creates a tight building

• Used primarily on old leaky maintenance buildings


UNCLASSIFIED10 of 36


Energy Efficient Windows

• Replaced majority of windows in older facilities

• Established a minimum standard for historical and commercial type windows for both repair and new construction

• Windows used must be:

– Thermopane insulated panel

– Low E glass

– Argon or Krypton filled

– 30-year replacement warranty

– Installed per manufacturer’s guideline to provided tightness seal and vapor barrier




A typical example of many large ground coupled heat pump projects constructed at Fort Knox. This 5-building complex (140K ft2) was disconnected from natural gas and connected to a geothermal ground coupled heat pump system (containing 130 500-ft deep wells)

Ground Coupled Heat Pumps

Facts:

• ~6 million ft2 of “eligible” 12 million ft2 heated and cooled from constant earth temperature

• ~5000 wells (500 ft deep) to couple with the earth temp of 57°F

• ~900 miles of underground piping

• 3 leaks in system in 9 years, fixed by installer

• HVAC-automation team Nolin/Harshaw-Trane




Renewable Methane Gas

• Drill renewable energy from below Fort Knox that is trapped within the Devonian Shale

• Entire project conceived and accomplished at no cost to the government

• Gas production began in January 2009

• Gas price is indexed to 86% of the NYMEX spot price

– Government saves transportation and marketing fees

– Government has a pricing cap of $11.00 per MCF

• Provides enough gas for entire summertime load
