Impact of E4 Training and Field Auditing of GSA Heartland Region Facilities

To assess the impact of energy efficiency expert evaluation (E4) training and field audits performed since 2007, the Federal Energy Management Program (FEMP) undertook a follow-up study on the implementation of E4 recommendations and an analysis of energy savings. The building property manager and O and M contractor of each facility were interviewed to obtain feedback and implementation status of the E4 recommendations. Overall, there were more than 160 recommendations documented in the E4 reports; about 50% of these recommendations were fully implemented and the remaining 50% either partially implemented or not implemented. In four buildings, the E4 recommendations were aligned with American Recovery and Reinvestment Act of 2009 (ARRA) projects replacing HVAC equipment or upgrading the building control system. The E4 recommendations were not followed-up in two buildings because of uncertainty of the long-term use of the facility or personnel changes. Results of this followon study are reported in this document.
