The report details the outcomes of the General Services Administration's (GSA) National Deep Energy Retrofit (NDER) program and a subsequent stakeholder workshop held in April 2014. It compares the energy savings of GSA's deep retrofits against other federal agencies and identifies systemic barriers and best practices in the Energy Saving Performance Contract (ESPC) process, focusing on project delivery, team dynamics, integrative design, operations and maintenance (O&M), and project economics.

This guide by RMI provides building owners and managers with a framework for specifying and procuring building energy modeling (BEM) services for new construction, renovations, and operational improvements. It details the benefits of BEM, the different purposes for modeling (comparison, compliance, and prediction), the role of the modeler, and the contracting process, including a sample Request for Proposal (RFP).

The GSA Net Zero Renovation Challenge is an initiative by the General Services Administration (GSA), the Office of Federal High Performance Green Buildings (OFHPGB), and the Federal Energy Management Program (FEMP) to achieve deep energy savings in 30-35 federal buildings using Energy Savings Performance Contracts (ESPCs). A workshop held in October 2011 by RMI and GSA identified structural, contractual, and technical barriers to achieving net zero energy, proposing a shift toward integrative design, streamlined procurement, and shared risk to move beyond conventional shallow retrofits.
