Level: Introductory

This training will educate attendees on how to use the eProject Builder (ePB) greenhouse gas (GHG) calculation tool to develop estimates of project GHG emissions, and to compare different project scenarios' potential GHG emissions impacts.

This tool provides federal agencies with a straightforward, user-friendly way to estimate the annual GHG emissions impacts of proposed projects, incorporating the estimated project energy savings and information from EPA's Emissions & Generation Resource Integrated Database (eGrid).

Attendees will learn which data inputs are required and how to complete the ePB data template inputs to develop the GHG calculations. They will also learn how to enter savings for various energy and fuel types, and how those entries impact Scope 1 and Scope 2 emissions impacts.

Lawrence Berkeley National Lab (LBNL), on behalf of the U.S. Department of Energy's Federal Energy Management Program (FEMP) recently released the new GHG calculation tool in the ePB project data template.

This tool was developed to support federal agencies' need to report GHG impacts of energy projects and decarbonize the energy use of their buildings and meet several federal mandates and targets, including helping to meet the net-zero emissions goals of Executive Order 14057, Catalyzing Clean Energy Industries and Jobs through Federal Sustainability.

Learning Objectives

Upon completion of this course, attendees will be able to:

  • Identify key federal reporting requirements for ESPC, UESC and direct-funded energy retrofit projects, for which this GHG tool will be relevant.
  • Receive an overview of the ePB system and project template relevant to being able to use the GHG tool.
  • Recognize which project data inputs are required for developing the GHG calculations in the ePB project data template.
  • Identify how to complete the ePB project data template for various energy and fuel types and how to complete the GHG tool using either the ePB non-calculating template or the ePB calculating template.
  • Identify how to enter fuel savings data for purchased vs. self-produced steam and chilled water—and how those relate to Scope 1 and 2 emissions; Identify the correct eGrid region for the ECM- or project-level information provided.
  • Complete an example scenario that compares a "business as usual" project with a project designed to reduce GHGs (e.g., with a fuel-switching measure)—and compare the impacts on price, energy and cost savings and GHG emissions between the two scenarios.
  • Learn about future planned updates to the ePB GHG calculation feature.


Chris Tremper, Program Analyst, FEMP

Chris Tremper has more than 25 years of experience providing analytical support to the FEMP.

From 1990 to 2008, he managed multiple energy analysis contracts supporting FEMP, the U.S. Department of Agriculture, the U.S. Department of Homeland Security, and the U.S. Forest Service.

He has developed and implemented energy data reporting protocols that have endured for more than a generation, accommodating the evolving needs and policy goals during that time.

Tremper joined FEMP as a federal government employee in 2008. Most recently, he provided key data and analytical support to the White House Council on Environmental Quality to help frame new federal goals and assisted agencies in revising greenhouse gas reduction targets under Executive Order 13693.

Tremper has a bachelor's degree from Wittenberg University in Springfield, Ohio.

Elizabeth Stuart, Program Manager, Researcher, LBNL

Elizabeth (Liz) Stuart has worked at LBNL since 2009. She leads software development and stakeholder engagement for eProject Builder, the U.S. Department of Energy's secure, web-based, energy project data management system.

She has been lead or co-author on more than two dozen LBNL reports and peer-reviewed journal articles on a range of topics including energy service company industry market and project trends, measurement and verification, building energy benchmarking, and energy efficiency and demand response programs and policies.

Shankar Earni, Program Manager, LBNL

Shankar Earni is a program manager in Building Technologies and Urban Systems Division, at LBNL, supporting FEMP to develop, implement, and evaluate energy projects, including developing processes, tools, and resources to enhance the adoption of alternate financing mechanism for energy projects.

Prior to LBNL, he worked as a senior performance assurance specialist at Johnson Controls Inc., where he was involved with auditing, project development, and implementation of energy projects in commercial buildings.

Shankar also led and participated in several energy audits for industrial and commercial sectors to identify energy and productivity savings.

He received his Ph.D. in industrial engineering and management and an M.S and B.S in mechanical engineering. He serves as a member of IPMVP committee, which is responsible for improving state of M&V practices.

Kurmit Rockwell, PE, CEM, LEED AP, FEMP

Kurmit Rockwell serves as energy savings performance contract (ESPC) program manager where he oversees services, tools, and resources needed to assist agencies with implementing successful ESPC projects.

Over a career spanning 25 years, Kurmit's work included engineering and all aspects of ESPC project implementation for federal, state, and local governments.

His work in the public and private sector energy services industry has focused on evaluation and implementation of energy and water cost saving technologies, smart building energy optimization services, renewable energy systems, and demand side management.

He holds a bachelor's degree in chemical engineering from Polytechnic Institute of New York University and a master's degree in building systems engineering from the University of Colorado. He is a registered professional engineer in multiple states.
