Measure Workbook Update Summary Latest ProCost template used for this measure workbook; workbook formatted, sourced, and made easily updatable. Measure EUL updated using DEER. Source for previous workbook: PGE 2007 workpaper. Previous workbook assumed that the EUL of the motion sensor was the same as the LED EUL The proposed EUL value is derived using EUL of Occupancy Sensors in DEER No change in EUL value (8 years) Minor updates made to cost calculation Units were adjusted to match energy savings units Updated cost is 2 cents less than previous cost Cost deflated to 2006 $.

Measure Workbook Update Summary Literature research conducted to understand if measure specification needs to be updated. PECI was consulted as well as part of this literature research. No new M&V study for Grocery Store Display Case Motion Sensor was found A case study by SMUD estimated that savings are approx. 41% of baseline use.SMUD A ComED Fact Sheet states that savings are approximately 30 % of baseline use.ComED Proposed workbook estimates that savings are 30 % of baseline use. Baseline wattage for this measure was updated by weighting with PECI ESG data. Current base wattage: 7 W and 3.5 W Proposed base wattage: 6.3 W and 3.2 W The UES calculation methodology remain unchanged.

Items for RTF Discussion None.

Summary of Changes Energy savings has reduced slightly. By an average of 10 % Costs have decreased as well. Decrease by 2 % EUL remains the same. Slight increase in TRC.

RTF Proposed Motion: I _________ move that the RTF approve the Display Case Motion Sensor Small Saver measure to “Proven” category with “Active” status with a sunset date of July, 2018
