Planning for Energy Cost Reduction Projects Get into the W eeds • Understand current consumption – Energy consumption by site – Focus on major end uses of energy – Utilize sub-metered data – Look at demand profiles and time of use • Look at your energy expense – Allocate expense into high level buckets • Consumption • Demand • Capacity 4
Evolving Opportunities • Fruit that has fallen – Implement easy to make operational changes that can be implemented through existing control devices • Setpoints • Setbacks • Low hanging fruit – Projects with a relatively low cost, quick payback, that are easy to implement • Stretch projects – Look at holistic savings opportunities by considering non-energy impacts such as maintenance and asset availability – Put multi-year strategy in place 5
Demand Response and Peak Load Shaving Maxim izing Existing Program s • Prior to 2016, Giant Eagle participated in traditional demand response programs by Event Typical lowering electricity demand in supermarkets Loads Loads • In 2016, Giant Eagle began to monitor instantaneous load on PJM and engaged demand response load shed during peak times to lower our capacity tags for the following year • Increased events required: – Additional resources devoted to program – Increased communication to supermarkets and internally at corporate – Measurement and verification of performance 6
Retro-commissioning Optim izing Efficiency of Existing System s • Validate system setpoints are in line with internal standards • Identify and correct where equipment is not operating properly – Broken lighting contactors – Bypassed VFDs – Inefficient compressor • Measured and verified savings of 10% energy reduction on major building systems • Filled in information gaps – Large HVAC units without VFDs 7
LED Lighting Significant Reduction Over Tim e • Implemented Over Five Years – Started with backrooms and stock areas – Convivence Stores – Salesfloor, Cases and Exterior • Energy Efficiency Win – Reduce a major end use of energy by more than 40% – Implemented along with dimming and other controls • Auxiliary Benefits – Lowered maintenance costs – Fewer outages – Improve aesthetic 8
Current Projects Better I nsight and Control • Centralized system information platform – Pulling in major system settings and data into holistic platform – Creating insight across entire portfolio in real-time • Advanced HVAC control – Reactive, dynamic controls – More sophisticated control strategy 9

Capital Projects Best Practices LED Lighting Winter 2015/2016 Fall 2016‐Spring 2017 2018 2019 Specialty Fixtures Parking Lot Lights and Campus LEDs DC Evaluation DC 2 Redesign Interior desk spaces in Conversion of DC High Some decorative lighting the HO, campus stores, Bays, Office Spaces, and End of 2015/Early 2016 and some exterior lights installation of advanced Parking lot lights and on buildings lighting controls some exterior fixtures were changed to LEDs. We are at 0.5 watts per square foot in high bay DC2 redesign included areas and economics to lighting at 0.5 watts per LEDs did not make sense square foot (0.4 when we did the HO watts/square foot below code) Note: All lights are scheduled via schedules in EMS or Occ sensors 16
Capital Projects Best Practices Data Center 2015 2016 2017 2018 ~92% Virtualized & Over 94% Virtualized Hot Aisle Containment ~ 95% Virtualized & Virtual Desktop & Air Side Economizer replaced battery backup rollouts Raised operating Continued replacement End of 2015/Early 2016 setpoints inside data of antiquated Parking lot lights and center expanding the equipment some exterior fixtures hours of using outside were changed to LEDs air temp 17
Capital Projects Best Practices VFD Compressors 2015 2018 2017 2018 DC2 Now Operating One compressor fails and we with Old DC1 install one with a VFD Compressors By end of the year all 3 DC2 shuttered for compressors were extended period and swapped out had compressors salvaged and taken to DC1 18
Operational Project Best Practices 19
Operational Projects Best Practices Scheduling/Setpoints 2015 2016 2017 2018 EMS Setpoints on DC Cooling Setpoints Raised in Campus LEDs Chiller Loop Setpoints DCs Conveyors Raised & More Aggressive Lighting Schedules Increased cooling Scheduling updated for HO & DC Setbacks reduced from setpoint and became spaces, exterior daytime 20 minutes to 7 minutes Holiday setbacks more more aggressive on coding was updated aggressive and nighttime setback investigation into the schedules for HVAC freeze protection looking more at recovery setpoints/scheduling time and other factors 20
