Energy Exchange: Federal Sustainability for the Next Decade2

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.


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.


PNNL – NAVY

• PNNL analysis mapped eight Navy building to ASHRAE 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

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

•Use most accurate estimation method (model, region median, or climate zone median) to fill gaps in facility energy consumption


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


Plan

Check also with AM to make sure the building is not on the demo list for at least another 20 yearsVerify with Sustainment Restoration and Modernization the building does not have other planned initiatives

Proceed with the eROI Tool


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


Project lifecycle is updated in the Energy PortfolioSavings are captured based on project status

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.


Metering


• 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.
