The Federal Energy Management Program (FEMP) provides a variety of tools to help federal agencies identify, develop, and implement energy and water efficiency and renewable energy projects that may be funded by appropriations. These tools are useful in the project identification, development, and post-installation phases.

Project Identification and Development

If the project is appropriations funded and using standard energy conservation measures (ECMs), reliable estimates of savings can be obtained by using the Investment Grade Audit (IGA) Tool developed for the Energy Savings Performance Contracts (ESPC) ENABLE program by Oak Ridge National Laboratory.

The IGA Tool addresses the following standard ECMs:

  • Lighting
  • Water
  • Simple heating, ventilating, and air-conditioning (HVAC) controls
  • HVAC packaged system replacements
  • Boilers and chillers
  • Solar photovoltaics.

If the appropriations funded project includes distributed energy technologies, such as renewable energy and battery storage, federal agencies can use the REopt Lite tool, developed by the National Renewable Energy Laboratory. REopt Lite addresses solar photovoltaics, distributed wind, and battery storage.  

Federal agencies interested in implementing distributed energy projects can request project assistance through the FEMP Assistance Request Portal and view information about federal on-site renewable energy project financing options.

Post-Installation Publications and Tools

The following publications and tools can be used for features that contribute to maximizing the savings from installed projects through services including commissioning, post-installation measurement and verification (M&V), and annual M&V reporting.

Combining Appropriations with Project Financing

In addition to available appropriations, the agency may have access to private financing for ECMs, including but not limited to FEMP's ESPC, ESPC ENABLE, and utility energy service contracts programs. 

Mixing Appropriations and Private Financing to Meet Federal Energy Management Goals, a study by Oak Ridge National Laboratory, shows how leveraging appropriations with private financing can maximize savings and minimize overall life-cycle cost.

Project facilitators can provide technical review and serve as owner's representative in appropriations funded projects.

EISA 432

Section 432 of the Energy Independence and Security Act of 2007 (EISA 432) requires federal agencies to identify "covered facilities" that constitute at least 75% of their total facility energy use as subject to the requirements of the statute.

See EISA Federal Facility Management and Benchmarking Reporting Requirements for EISA 432 reporting including sections on guidance and tools.
