11. Energy Exchange : Federal Sustainability for the Next Decade 11 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.

12. Energy Exchange : Federal Sustainability for the Next Decade 12 PNNL – NAVY PNNL analysis mapped eight Navy building to ASHRAE reference buildings

13. Energy Exchange : Federal Sustainability for the Next Decade 13 Map Navy Building types to ASHRAE Eight Navy building types directly map to PNNL 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 Use Relationship to Establish Benchmark 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 Repeat for each Building Type and 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 Benchmarking Methodology

14. Energy Exchange : Federal Sustainability for the Next Decade 14 Benchmark Development Process For the building that a BM is being created: Navy Installations located in 11 of the 17 ASHRAE climate zones, BM are needed for 17 building types, 187 optimization problems

15. Energy Exchange : Federal Sustainability for the Next Decade 15 Example  Utilize non-linear optimization to establish weights which relate medians of buildings with established benchmarks to the median of Navy-specific building type Medical Facilities Office Primary & Secondary Schools Stand-Alone Retail Transient & Visitor Housing Warehouse Maintenance Facility Median Median EUI 51.4582.7244.5061.5283.7718.13 = 31.70 Weight0.110.060.130.080.060.34 Medical Facilities Office Primary & Secondary Schools Stand-Alone Retail Transient & Visitor Housing Warehouse Maintenance Facility Benchmark 124.135.554.550.538.117.2 = 34.3 Weight0.110.060.130.080.060.34  Multiply established benchmarks by respective weights to derive benchmark for Navy-specific building type  This process is repeated for each building type – climate zone combination

Energy Exchange : Federal Sustainability for the Next Decade 21 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

22. Energy Exchange : Federal Sustainability for the Next Decade Project lifecycle is updated in the Energy Portfolio Savings are captured based on project status 22 Track Planned - a project has not been accepted into a program of record. Programmed - the project has been reviewed, approved, and included in a program of record. Project should be undergoing planning/design through the acquisition process, up to award Awarded - Project has been awarded and is currently under construction Operational - Project has been completed and accepted by the government. If required, project should be undergoing measurement and verification of energy savings during the payback period.

24. Energy Exchange : Federal Sustainability for the Next Decade Enterprise solutions and data transparency has helped us with decision making and collaboration amongst the stakeholders. These solutions were developed keeping the end users in mind. If the process was not to serve a purpose across the enterprise and at any level (F, I, R,N) it would not be incorporated in the system of systems. 24 Summary
