1 Net Zero Case Studies Army Reserve and Net Zero Paul Wirt Army Reserve Installation Management Directorate Chief, Sustainability Programs Branch August 16, 2017 Tampa Convention Center Tampa, Florida

2 Army Reserve Net Zero Program 2011 Army initiated a Net-Zero (NZ) program to establish NZ energy, water, and/or waste goals which included three U.S. Army Reserve (USAR) installations Fort Hunter Liggett (energy, waste) Parks Reserve Forces Training Area (energy) Fort Buchanan (water) 2

3 Army Reserve Net Zero Program 2013 Army Reserve expanded Army s NZ Program to include Army Reserve Centers (ARC) 10 Reserve Centers participating in pilot program representing all regions and facility types George W. Dunaway ARC in Sloan, Nevada Kaoru Moto ARC in Maui, Hawaii Joliet ARC in Elwood, Illinois Orlando ARC in Orlando, Florida Tanapag ARC in Saipan Vincente T. Dydasco ARC in Guam CPT Euripides Rubio ARC in Puerto Nuevo, Puerto Rico Pele ARC in American Samoa Roosevelt Roads ARC in Ceiba, Puerto Rico March ARC in Riverside, CA Pursuing NZ energy, water, and waste at each site 3

4 Why NZ for USAR? Optimizes operations Environments that provide the necessary resources optimize mission readiness Demonstrates USAR commitment to NZ Only Federal NZ program that integrates energy, water, and waste Provides regional context for site-specific opportunities Considers Reserve Center s impacts to the local community and vice versa Site assessments can be utilized in the future Net zero solutions are identified that may become economic or necessary Data collected in these assessments could be used to analyze future opportunities 4

5 NZ Energy Case Study: Maui USARC RECIPIENT LEEP AWARD

6 Maui Project Summary Energy Projects Complete In Progress Potential NZ champion BEM program, NZ training LED lighting AC condenser HVAC right-size upgrade Additional AC Controls (PIR thermostats) 99 kw PV Solar water heater Replace doors, windows Ceiling insulation Water Projects (82% Reduction) Complete Potential Upgrade plumbing Irrigation O&M Irrigation controls BEM program, NZ training Native landscape 6

7 Maui Successes 39% energy savings FY13 FY16 99 kw PV system and envelope improvements expected to achieve 100% savings in FY17 77% water savings FY13 FY16 Soldiers installed LEDs and efficient plumbing fixtures Saved over $300k in project installation costs Received Military Occupational Skill training Recognition LEEP Highest energy savings in a parking lot light retrofit DOE Interior Lighting Campaign exemplary federal government sector Utilized 4 funding mechanisms (6 were explored) High level of support Leadership Onsite NZ champion Technical support for project development 7

8 Maui Challenges Net metering agreement took years Increased project costs Moved to roof requiring installation of new roof Legal review was required 3 times due to changes in command and to the project over this period of time PV system malfunctions Results in loss of production Functionality changes increase energy consumption requiring additional efficiency measures to offset AAFES request for additional A/C Increased use of kitchen planned 8

9 Maui NZ Progress through June 25,000 Construction on site 20,000 PV panel malfunction PV inverter malfunction Electricity Consumption (kwh) 15,000 10,000 5,000 0 Actual Purchased Electricity Actual PV Production Actual Excess PV Production Estimated PV Production Estimated Excess PV Production PV array came online (May 19) -5,000-10,000 * Estimated consumption assumes site consumption increases 3% per month in summer, and PV production is equal to 8% over PV Watts monthly production estimates (based on historical trends) 9

10 NZ Water Case Study: Fort Buchanan 10

11 Fort Buchanan Project Summary Fort Buchanan s NZ water objective Fort Buchanan will reduce potable water consumption volumetrically by 60% through water efficiency and use of alternative water sources Water Projects Complete In Progress Potential High efficiency plumbing upgrades Irrigation wells Potable wells installed Rainwater harvesting for non-potable uses Rainwater harvesting for potable use Advanced meters installed Potable distribution system upgrades Wastewater treatment plant Cemex Lake acquisition 11

12 Fort Buchanan Successes FY13 ESPC Project 1 completed Installed high efficiency toilets, urinals, and showerheads Estimated savings from plumbing retrofits is approximately 7.7 Mgal per year Well system installed for golf course irrigation FY14 and FY15 ESPC Project 2 completed Leak detection survey completed 8 large leaks found and repaired Potable well constructed Rainwater harvesting systems installed at the Middle School, AAFES Main Store and AAFES PXTra, Bowling Center, High School, Gym and Community Club Harvested 1.28 Mgal last year for toilet flushing and irrigation 12

13 Fort Buchanan Successes, cont. Four phase distribution system replacement is underway to upgrade the potable distribution system Phase 1 is nearly complete Phase 2 to begin end of FY17 or beginning of FY18 Phases 3 and 4 will follow Installation Technology Transition Program (ITTP) funded potable rainwater harvesting system Being installed at the Welcome Center in FY17 Will provide approximately 55 kgal per year of potable water Sufficient to meet all of the potable water needs for the Welcome Center System will be solar powered with a five day battery autonomy 13

14 Fort Buchanan Challenges Reliant on local utility (PRASA) for water and wastewater services Have limited onsite production from wells Pursuing onsite wastewater treatment plant, but there is limited land space for new construction Aging distribution system with a high leak/loss rate Leaks/losses estimated to be ~40% of the total water use at Fort Buchanan Analysis revealed the distribution system was built in the 1950s with an expected life of approximately 60 years 14

15 Fort Buchanan The Future Wastewater Reuse Under Consideration - Packaged, Modular Membrane Bioreactor System - Small footprint, less expensive than conventional brick and mortar - The effluent could initially be used for golf course irrigation, vehicle wash, and cooling towers - Eventually could be treated to potable standards 15

16 NZ Waste Case Study: Fort Hunter Liggett 16

17 Fort Hunter Liggett Project Summary Qualified Recycling Program (QRP) Gasification system converts waste to energy Considering composting program for diverted food waste 17

18 Fort Hunter Liggett QRP Launched in January 2013 Program built in 2 years doubled amount of waste recycled Generated just over $1M in first two years All recycling eliminated from Fort Hunter Liggett s Waste Management Contract due to key partnerships with the State of CA $84K annual cost savings 18

19 Fort Hunter Liggett Waste-to-Energy FastOx gasification technology will begin demonstration Q4 FY17 Gasification process heats waste at high temperatures to break down waste into energy-rich gas (syngas) Can process 10 tons/day max Phase 1: produce syngas Phase 2: generate electricity 19

20 Fort Hunter Liggett Successes Senior leader support Extremely successful QRP created multiple partnerships in CA Awarded ESTCP for WTE facility 20

21 Fort Hunter Liggett Challenges Remote location Transportation and labor costs can have significant impact No offsite access to WTE facilities Little surrounding offsite waste to supplement onsite waste for gasifier Local municipalities recently agreed to provide additional waste for gasification Will explore gasification of C&D waste when feasible WTE construction delays Delivery of equipment Permitting 21

22 Conclusion NZ energy has proven to be easiest to achieve, both financially and technically NZ water is feasible only when sites are located within the watershed of their source water Technologies used to achieve NZ water are not mainstream and present permitting and cost challenges NZ waste is very difficult to achieve WTE is the only solution identified for materials that can t be diverted Reduction and diversion opportunities are often based on factors outside of site s control USAR will continue to identify NZ opportunities and implement projects to work toward NZ goals, increasing resiliency and resource longevity. 22
