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

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

Net Zero Waste

Say No to Styrofoam

Improve procurement � Eliminate packaging, use bulk dispensers,

recycled/recyclable content, take-back policies) Donate excess items

� 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
