Renewable Energy Goals

• 10 USC §2911 (e) Energy Performance Goals & Master Plan for the Department of Defense

– Goal of producing 25% of facility energy with renewable energy sources by 2025.

• Executive Order 13423

– Reduce energy intensity by 3% annually, leading to 30% by the end of 2015.

– 57.62% decrease in Energy Use Index (EUI) from 2003 to 2014.


Renewable Energy Goals

• Executive Order 13514

– Reduce potable water intensity by 2% annually, leading to 26% by the end of 2020.

• The Net Zero Initiative


Building Controls Strategy

• KYARNG facilities are integrated into a web-based building automation systems

– Reporting, trending, scheduling, control

• Occupancy schedules and other building parameters are tuned to accurately match facility operation and maximize the benefit of energy consumed

• Advanced Metering Technology


Integrating Sustainable Design

• Incorporating energy saving techniques during design such as: – Insulation & Durable Materials, Building Envelope

– Building Orientation, Daylight Harvesting

– Efficient HVAC & Ground Source Heat Pumps

– Efficient lighting & Controls

– Cool Roof Systems

• ANSI/ASHRAE/IESNA Standard 90.1 (2004)

• 200 KAR 6:070

• LEED Silver


Harnessing The Earth:

Geothermal • Facilities with GSHPs:

– Richmond Armed Forces Reserve Readiness Center

– Richmond Armory Expansion

– Richmond Field Maintenance Shop

– Morehead Readiness Center

– Burlington Readiness Center

– Harlan Armory

– NEW Army Aviation Support Facility

• 108 wells at 400ft deep

• $0.21/SF/Year in savings


Powered by the SUN

• In 2014, the KYARNG total solar production was 824,899 kWh.

• Projected 1.5 MW of PV installed by the end of 2015.

• Estimated 15% of KYARNG total electric from PV by the end of 2015.

Long Lasting Luminaries

• Upgrades of outdated luminaries serves as a simple method of reducing energy consumption and maintenance costs.

• LED luminaries

• Photo/motion sensors

• Daylight Harvesting

Case Study: MATES, FT Knox

• The KYARNG has seen its largest reductions when pairing lighting upgrades, both interior and exterior, with the installation of solar photovoltaic systems


Case Study: MATES, FT Knox • Phase 1: Upgrading Exterior Lights & PV Install

– LEDs reduced demand by 79.6KW

– 50 KW Solar

• Phase 2: Interior Lights & Controls

– LEDs reduced demand by 17.9KW

– 30 Daylight Harvesting sensors

– Over 100 Occupancy sensors

• Phase 3: Recoverable Energy

– De-stratification Fans

– Used Oil Furnaces
