  4. USAG – Ft Hunter Liggett • Increase energy efficiency • Conserve and protect water resources • Eliminate waste and recycle • Leverage agency acquisitions to foster markets for sustainable technologies • Construct, maintain, and operate high performance sustainable buildings Executive Order 13514 todd.a.dirmeyer@us.army.mil 4

  5. USAG – Ft Hunter Liggett Definition of Net Zero – Energy Initiative A Net Zero Energy Installation (NZEI) is an installation that produces as much energy on site as it uses, over the course of a year.To achieve this goal installations must first implement aggressive conservation and efficiency efforts while benchmarking energy consumption to identify further opportunities. The next step is to utilize waste energy or to "re-purpose" energy. The balance of energy needs then are reduced and can be met by renewable energy projects. Energy Security is the foundation of the NZEI! Solar Hot Water Solar Vent Preheat Ground Source Heat Pump Daylighting todd.a.dirmeyer@us.army.mil 5

  16. USAG: Ft Hunter Liggett GSHP 10.6% ECIP Solar PV 21.7% Load Shifting Thermal Storage 1% Solar PV Electrical Storage 5.3% UNICOR Solar PV 20% Building Envelope Upgrades 3.3% Waste to Energy System 5.7% Hydrogen Fuel Cell 1% Micro Grid 1% Solar Hot Water 3.5% Secondary Waste Water Treatment 1% LED Lighting 9.3% Internal Efficiency Efforts 5% Daylighting 1.7% 10% todd.a.dirmeyer@us.army.mil 16

  17. USAG – Ft Hunter Liggett • Lessons Learned • Energy management staff (maintenance & operation, EMCS) • PG&E Rule 21 limitations • PG&E transmission limitations….may force FHL to “island” • Funding (small energy conservation projects) • PG&E rebates and savings from UNICOR task orders • SRM • FY13 POM QUTM funds (electrical distribution upgrades and building envelope upgrades) • Sprawl – new facilities with no demolition/consolidation • Energy Master Plan must be integrated with Installation Master Plan todd.a.dirmeyer@us.army.mil 17
