Launched as a Pilot Evolution Army Directive
2014-2‒ Army-wide
implementation‒ Integrated design
with Net Zero end goal
Embedded in policiesEnergy pilots: 9 Water pilots: 8

Net Zero Energy
Fort Huachuca, AZ
Tools: Energy efficiency assessments Renewable energy assessments
Start with aggressive demand-side energy use reductions‒ Combine with awareness campaigns to influence behavior
Maximize energy efficiency in new construction, life-cycle equipment replacement, O&M practices
Recover waste energy for secondary use‒ Boiler stack exhaust, building exhausts, & other thermal energy
Recover heat from the electricity generation process Meet the reduced demand with (on site) renewable energy
solar hot water
solar pool
Net Zero Water
Tools: Water balance assessments Net Zero Water roadmaps
Start with water conservation‒ Detect & fix leaks‒ Combine with awareness campaigns to influence behavior
Maximize efficiencies ‒ New construction, life-cycle replacements, O&M practices
Water reuse strategies (e.g., grey water & purple pipe) Water security & reliability strategies, including alternate
water supplies
Synthetic TurfRapid infiltration

Net Zero Waste
Say No to Styrofoam
Improve procurement � Eliminate packaging, use bulk dispensers,
� Edible food, furniture, office supplies, deconstructed building components, etc.
Treat waste as a ‘product’ with other uses Target major waste streams (e.g., organics) Energy recovery (after avoidance/diversion) Landfill is a last resort
Tools: Waste characterization Material flow analysis
