10. Energy Exchange : Federal Sustainability for the Next Decade 10 Current C&I Projects  C&I 5. ENERGY STAR Fryers Scaled Field Placement Technology: Scaled field placement; testing EnergyStar & low oil volume fryers that reduce natural gas use, extend life of oil, and reduce oil disposal costs Purpose: The project will determine the energy savings potential and market barriers to energy efficient fryers by conducting field evaluations of various models in 17 commercial kitchens. To accelerate market transformation. Deliverables: Final report on the findings of 17 field installations. Findings/Timing: Final report is delivered in Q1 2015. 3 additional sites are tested in 2015. Fryer rebate claims jumped from 209 in 2013 to 1,001 in 2014.

11. Energy Exchange : Federal Sustainability for the Next Decade 11 Current C&I Projects  C&I 6. Lang On-demand Stove-top Field Testing Technology: A new product, a commercial stove-top that automatically shuts off the burner when the cooking utensil is removed. Purpose: Field testing in 3 restaurants to determine the user behavior, market barriers, customer acceptance, and energy savings potential of the Lang 4- and 6-burner on-demand models. Deliverables: Final report can help manufacturer improve product, and inform potential EE programs for incentive applications. Findings/Timing: Preliminary results indicate about 20% savings. Field data collection is nearing completion. The final report was in Q4 2014.
