Persistence of savings: ComEd EBCx


Slipstream.org, a Wisconsin nonprofit firm that merged Seventhwave and Wisconsin Energy Conservation Corporation effective January 1, has published, “Persistence of Savings from Retro-Commissioning Measures: A field study of past ComEd retro-commissioning projects.” The study includes primary research (building audits and equipment testing/performance measurement) and literature search results of persistence by measure and by energy savings in ComEd retro-commissioning (EBCx) programs over time.

Results, including factors that affect long-term performance, improvement of declining persistence with “trigger-elevated support,” and program recommendations are included in the report. The study suggests that these triggers, such as turnover of key building personnel and equipment or automation system retrofits, can be managed to help ensure higher persistence.
