The Duluth Energy Efficiency Program (DEEP) is Ecolibrium3’s flagship program. DEEP provides both home energy assessments (or “walk through” energy audits) and advanced home energy assessments (blower door and infrared testing, etc.). Walk through assessments are free of charge. Although there is a modest charge for the Advanced Home Energy Assessments (AHEA), rebates are available to offset the cost through both ComfortSystems and Minnesota Power. Free assessments are available to those who income qualify.

DEEP is also currently working on Duluth’s entry into the Georgetown University Energy Prize Competition. To learn more about our efforts with community partners check our team’s website at
