At a Glance
Display cases can be found in most grocery stores, and in some restaurants and grab-and-go cafes. They keep food and beverages well lit and chilled while awaiting purchase. This measure covers the energy savings achieved from medium and low temperature display cases where light bulbs in the case are retrofitted with LED alternatives, or where lamps are removed. Also, this measure workbook includes energy savings estimates from the installation of motion sensors on display case lighting systems to decrease lighting run time, and thereby, energy use. Combined measure workbook for both LEDs and motion sensors, in both reach-in cases and open cases. All motion sensor measure applications are considered small saver. All LED measure applications are considered proven.

Decision details
Adopt measure updates
Decision DetailsAdopt the updates for the Display Case Lighting LED UES measure and the Display Case Lighting Motion Sensor UES measure as presented, and
- Change the Category to Proven for Display Case LED Lighting
- Keep the Category at Small Saver for Display Case Motion Sensors
- Keep the Status at Active
- Set the sunset date to May 31, 2023
- Change the analysis to assume that those LED lamps within refrigerated case have HVAC interactions (instead of refrigeration) based on a fraction assumed in the DOE TSD
- Change assumption of LED lifetime hours to 50,000
- Change assumption of weighting of 18-hour store and 24-hours stores to 50% each, and make the corresponding change to controlled hours
Approve measure update
Decision DetailsApprove the proposed analysis for LEDs for Display Cases UES and: •Deactivate New Case measures for Reach-In cases •Combine the Reach-In and Open case into one Grocery Display Case LED measure as proposed •Set a Sunset Date of July, 2019
Approve measure update
Decision DetailsApprove the proposed analysis for existing cases for Grocery Open Display Case Lighting UES and set the sunset date to July, 2019. Keep status as Active, Keep category as Small Saver
Measure deactivation
Decision DetailsDeactivate the new case measure applications in the Grocery Open Display Case Lighting UES measure.
Approve measure update
Decision DetailsAdopt the delivery verification guidance as presented for the following measures:
- Com Grocery – Display Case LEDs (Open Cases)
- Com Grocery – Display Case Motion Sensors
- Com Grocery – Floating Head Pressure Controls for Single Compressor Systems
- Com Grocery – Strip Curtains
- Com Grocery – Walk-in Evaporator Fan EC Motor Controllers
- Com Grocery – Compressor Head Fan Motor Retrofit to EC Motor
- Com Smart Plug Power Strips• Com Traffic Signals – LED Traffic Signals
- Res Heating/Cooling – Electronic Thermostats

For LED display case UES measures, in phase II of its UES measure reviews project, the RTF will attempt to meet the recommendations in the recommendation memo.Based on the discussion at the RTF meeting, the motion sensor UES measure may be proposed as a small saver. The RTF will review that proposal, or a plan for collecting data necessary to bring the measure back into compliance, should either one be brought forward.
