Better Buildings Challenge Partners and Allies learned how Energy Savings Performance Contracting (ESPC) is expanding to new sectors to impact building energy efficiency. They also learned how you can take advantage of ESPCs to see long-term energy savings in your buildings with little or no upfront cost. A representative from the Department of Energy also introduced DOE’s ESPC Accelerator – a high impact program designed to support expansion of ESPCs among state and local governments.
