Description
The Energy Efficiency Investment Fund (EEIF), administered by Delaware’s Department of Natural Resources and Environmental Control (DNREC), helps non-residential facilities replace aging, inefficient equipment and systems. It supports retrofit and new construction projects that reduce energy consumption and operating costs while improving environmental performance. Qualifying improvements must exceed minimum energy code requirements.
Four pathways cover targeted or comprehensive energy assessments, common equipment upgrades, custom site-specific improvements, and combined heat and power (CHP) systems. Prescriptive rebates cover lighting, HVAC and water heating, and appliances and food service equipment. Custom rebates address non-standard measures and comprehensive facility upgrades. CHP supports simultaneous electricity and useful heat production, particularly at facilities with high operating hours and thermal loads.
