Topic
Share the value, uses and ROI of a robust BM and analysis regime Navy has developed in order to provide our energy managers actionable information to identify, plan, execute and measure energy goals attainment.
Energy Exchange: Federal Sustainability for the Next Decade3
To assure superiority in the execution of its national defense mission, the Department of the Navy continues to value energy as a strategic resource to reduce consumption, invest in energy security and renewable power generation and implement culture and behavior.
DON Energy Program
Strategic approach is to ensure energy will never be an operational constraint to performing the mission

Building Benchmarks
• Compare facility energy use intensity (EUI) to a standard of excellence (benchmark) to identify poor performing Navy facilities to target with energy saving projects.
• Majority of building types are unique to the Navy so what standard would apply to our facilities and map to industry building energy benchmarks.
• Develop and implement gap filling for missing data and customize benchmark methodology by using DoE Energy model in accordance with ASHRAE 90.1-2010.
• For DOE, PNNL conducted analysis of reference to building energy use using ASHRAE 90.1-2010 specifications.
• The analysis provides EUI for 16 reference buildings in 17 climate zones.
• 8 Navy building types established directly map to PNNL reference buildings leaving 17 Navy buildings which do not map to established reference buildings.

Establish Relationship
•A relationship between the median EUIs for Navy building types that map to ASHRAE benchmarks and the median EUIs for unmapped Navy-specific building types is established using a non-linear optimization problem

•The calculated weights are applied to the ASHRAE benchmarks of the matched buildings types to determine the benchmark for the building type in a specific climate zone

•Navy installations are located in 11 of the 17 ASHRAE climate zones, and benchmarks are needed for 17 of 25 Navy building types, thus 187 optimization problems are solved

NSGEM: Plan
Navy Shore Geospatial Energy Module (NSGEM) is an interactive web map that uses information from authoritative data systems to visualize monthly energy use Navy-wide.More specifically, NSGEM: • Color codes all Facilities based on their energy use benchmarks• Assesses data completeness within authoritative sources and encourages users to update missing or
incorrect information• Produces energy consumption reports for various levels—Navy, Installation, Region, Facility and Tenant

Evaluate Project ROI
Energy Return on Investment (eROI) is a user-friendly web-enabled tool that facilitates project development and ensures financial viability. More specifically, eROI:• Ensures that project investments are comparable and yield favorable returns• Develops a weighted score using energy and non-energy benefits (i.e., energy reliability,
regulatory compliance, infrastructure improvements, operations and maintenance avoidance) • Informs Installation energy managers of funding likelihood via weighted scoring• Centralizes energy project data circa FY12
