2 Agenda 1 CNCI Project Description 2 MARFORRES New Orleans Site 3 Energy and GHG Analysis 4 Preliminary Results 5 Next Steps & Opportunities for Further Study

3 Acknowledgements This project would not be possible without the time and cooperation of the MARFORRES team: Col. William Davis - Assistant Chief of Staff for Facilities Lt. Col. Stanley Sober - Director, Real Property Alain Flexer - Energy Manager Howard Myrick - BRAC Project Manager Amy Carbonette - MARFORRES Facilities Innovation for Our Energy Future

4 FEMP Greenhouse Gas Program Mission: Facilitate the Federal Government's implementation of sound, cost-effective energy management and investment practices to enhance the nation's energy security and environmental stewardship. Public Sector Greenhouse Gas Accounting and Reporting Protocol Recommendations for Federal GHG inventories Climate Neutral Communities Initiative

5 Climate Neutral Communities Initiative (CNCI) CNCI applies a GHG lens to the NZEI systems approach to integrated decision-making and technology deployment Net-Zero Carbon. A Climate Neutral Community is a campus that balances a measured amount of greenhouse gases released with an equivalent amount sequestered over the course of a year. Encompasses scope 1, scope 2, and some scope 3 emissions. Innovation for Our Energy Future

6 Process overview The CNCI case studies will develop a cost-benefit analysis of different approaches that Federal campuses can take toward climate neutrality. 1. Establish Energy/GHG Baseline 2. Energy Efficiency Assessment 3. Renewable Energy & Load Reduction Assessment 4. Transportation Assessment 5. Electrical Systems Assessment (microgrid) Recommendations and next steps Innovation for Our Energy Future

7 Project Timeline The final CNCI case study will be submitted to FEMP by the end of FY10.

8 Background: Federal City New Orleans FCNO vision Public-private, mixed-use commercial and residential development 200 acres, 10,000 jobs, 1,400 residences New model for small military bases Sustainable development MARFORRES to become anchor tenants in Federal City Close New Orleans East Bank in accordance with the 2005 Base Realignment and Closure Commission. Innovation for Our Energy Future

9 Project Site The focus of the CNCI case study is the 29-acre MARFORRES Center secure compound. Secure compound Mixed-use campus Coast Guard Master plan courtesy of Federal City New Orleans (

10 Organizational Boundaries The CNCI analysis includes the following facilities: MARFORRES Headquarters Building (under construction) Existing Buildings (not operated by MARFORRES) H-100 (Herbert Building): mixed use offices, commissary, apartments H-101: Warehouse H-102: Central plant Quarters A (historic residence being transferred to MARFORRES) Photo credit: Megan van Wieren, EMC Engineers Innovation for Our Energy Future

11 MARFORRES Headquarters Building The MARFORRES HQ building comprises the largest component of the CNCI analysis. 400,000 sq ft facility (4 floors) Command center (top 2 floors) requires 24/7 up-time Data center Designed to LEED be certifiable Rendering courtesy of Federal City New Orleans ( Designed/constructed using state funding; building will be transferred to MARFORRES operation upon completion. Projected completion date: June, 2011 Progress as of April 12, 2010

12 Projected Energy Baseline Preliminary results for MARFORRES energy consumption baseline Annual Electricity Consumption (MMBtu/yr) HQ Energy Consumption by End Use Headquarters H-101 Quarters A H ,011 22,229 Exterior Usage 4% Domestic Hot Water 1% Ventilation Fans 5% Data Center (lights, equip, cooling, fans) 29% Space Cooling 17% Ambient Lights 18% Misc Equip 26% 270 Pumps & Aux 0% Space Heating 0% 166 Total energy consumption: 40,740MMBtu/yr

16 Micro-grid Assessment The micro-grid assessment will encompass the critical load required to keep the command center operational. Estimated critical load: 1 MW Backup power: kW diesel generators The purpose of the micro-grid analysis is to evaluate the potential to supplement the diesel generators with renewables to increase the run time of the generators. Innovation for Our Energy Future

17 Renewable Resources Solar PV Of the readily deployable renewable resources available, solar appears to be the only significant resource. Innovation for Our Energy Future

18 Renewable Resources Wind Of the readily deployable renewable resources available, solar appears to be the only significant resource. Innovation for Our Energy Future

19 Photovoltaic Siting The following areas were considered for PV systems: 1. HQ building roof 2. North parking lot 3. Parade ground Southwest VIP parking lot 7 5. Athletic areas 7 6. North walkway 7. Guard booths Total estimated PV generation capacity: 600kW (60% critical load)

20 Next Steps Finalize building models, ECMs, and microgrid analyis Transportation study Fleet Commuting Travel Evaluate LED lighting for outdoor areas Innovation for Our Energy Future

21 Summary The NZEI approach can also assist planning for climate neutrality. Based on preliminary analyses, the MARFORRES Center can potentially reduce its emissions by 37%. Significantly deeper energy and emissions reductions are realized by incorporating abatement measures into design. PV installation can increase the runtime of backup power system.
