SUSTAINABILITY
Why?
- Address high cost of business operations where we can save
money through use of more environmentally sound practices
- Address areas where our company has a higher environmental
footprint or impact
- Address areas where there is, or may be, a social or consumer
sensitivity that is relevant to our business
- Overall increased consumption of finite resources
How?
KROGER COMMITMENT
“[An]…example of our long-term focus is our progress integrating sustainable
practices into our business operations. We believe that customers and
associates increasingly make decisions based on how well companies take care
of their people, their communities and the planet. So we are very pleased to
share that Kroger has earned a spot on the Dow Jones Sustainability Index for
the 4th consecutive year…”
Rodney McMullen
CEO, The Kroger Co.
September, 2016
“Our approach to sustainability is a commitment to continuously improve our
environmental and social impacts in order to better our communities and the
lives of our customers and associates, and ensure the long-term success of our
business.”

WATER – Where’s it going?
WATER – AT STORE LEVEL
“What can we do at Store/Associate level?”
-
Check for water leaks (damaged equipment, running toilets, etc)
Over-watering irrigation / landscaping
Monitor water bills
Install tamper-proof faucet aerators
Install dual-flush toilet valves
Change out evaporative condensers to air (COSTLY)
-
RAISE AWARENESS – CHANGE THE CULTURE (from inception)
SAME THINGS YOU DO AT HOME!!

GreenChill
- Partnership with food retailers to reduce refrigerant
emissions and decrease impact on ozone and climate
change
Fugitive Refrigerant (Refrigerant Leaks)
- Support and uphold EPA regulations for tracking
- Prevent “Gas and Go”
Reduction Goals and Expectations
- Last year – Dillons reduced by nearly 20%
- This year – Goal is to reduce by another 20%
ELECTRICITY
“Why such the large focus?”
• 2,625 Grocery/Retail Stores
– 34 states (and DC)
– Nearly two dozen banners, and multiple formats.
• 782 Convenience Stores
• 326 fine jewelry stores
• 37 Food Processing or Manufacturing Facilities
• 1,330 Grocery Store Fuel Centers
• 65 Logistics Centers, and other facilities.
2014 Electric Usage = over 6.4 billion kWh
Figure out how to spend less…
ELECTRICITY – “TYPICAL” KROGER STORE
ELECTRICITY – REFRIGERATION
-
Energy Maintenance
Demand Defrost
Controls Programming
Demand Curtailment
Case Covers and Doors
Electrically Commutated Motors (ECM)
Floating Head Pressure
Hot Water Reclaim
Hot Air Reclaim
Variable Frequency Drives (VFD)
ELECTRICITY – LIGHTING
-
Lamp Retrofits – T12 to T8 or T5
LED Installation
LED Retrofit
Daylighting
Occupancy Sensors
Energy Monitoring
ELECTRICITY (and GAS) – HVAC
- Temperature Setbacks
- Save 3% per degree Fahrenheit
- Proper Relative Humidity (vs Dewpoint)
- Demand Control Ventilation

SAVE 5 GOALS
WHY?
- It’s the right thing to do / we have a responsibility as a large
corporation
- The average supermarket uses 625 times the amount of
electricity versus the average home
- Dramatically reduces operating costs of your stores
- NOTHING DIFFERENT THAN YOU DO AT HOME!
Close Doors
Turn Lights Off
Turn Equipment Off After Use
Maintain Specified Temperatures
Don’t Overstock
Source: Save5 Best Practices Document
http://Kroger.creativeop.com/
CLOSE DOORS
Exterior Doors
- Not just for temperature control, but also for humidity and store air
balance
Walk-In Freezer and Cooler Doors
- A cooler left open without strip curtains loses enough energy PER HOUR
to power 5 homes
Strip Curtains
- Properly installed AND USED strip curtains can preserve up to 80% of
refrigerated air…even IF the door is left open
Interior Doors
- Effectively stops cross-draft air (especially
when separate HVAC units are used to condition
different spaces)
Compressor Doors
- Stops the increased heat produced by
the equipment
Source: Save5 Best Practices Document
TURN LIGHTS OFF
Lighting
- Approximately 25% of the store’s total energy usage
- Equivalent to approximately 150 single family homes
- Even the most energy efficient lights produce heat
- Refrigeration and HVAC have to overcome the added heat
Lighting Setbacks
- Designed/Controlled to assist with turning lights off during nonbusiness hours, or during high ambient light hours
Source: Save5 Best Practices Document
TURN EQUIPMENT OFF AFTER USE
Turn off unused, or non-essential equipment
- SAVINGS - Turning off 1 hour per day for a year:
Rack Oven = $1,878
Pressure Fryer = $475
Meat Labeler = $473
Warm-Up Time – Use manufacturer’s recommendation only
Exhaust Fans
- Not only use electricity for the fan motor
- Creates HVAC load – have to condition the newly replaced air
CLEAN EQUIPMENT – filters, heating elements, fans, etc
Formulas:
- Watts = (Amps) x (Volts)
- kW = (Watts) ÷ (1000)
- Cost = (kW) x (# hours on per day) x Cost per kWh
Source: Save5 Best Practices Document
MAINTAIN SPECIFIED TEMPERATURE
Refrigeration = #1 electricity user
- Average store’s cases = 110 homes
- Average store’s compressors = 200 homes
Cases
- Too warm wastes product and labor
- Too cold wastes electricity
- THERE IS A HAPPY MEDIUM…SETPOINTS
Clean Equipment
HVAC
- Store/Room temps maintained at setpoints
- Keep dock doors and doors between dock and backroom closed
Source: Save5 Best Practices Document
DON’T OVERSTOCK
Overloaded Cases / Blocked Air Vents
- Wastes enough energy to power 50 homes
- Disturbs the air curtain
- Allows warmer air (from salesfloor) to enter the case
- Warms product
- Causes refrigeration to run more
- Creates product integrity / food safety issues for the warmer product
Source: Save5 Best Practices Document
SAVE 5 - SAMPLE
- Store Savings Example – Goal = 3% savings
2009 Save 3%
Store Used: 3,631,836 kWh = $244,476
Equates to $.0673/kWh
Any other ideas?
108,955 kWh = $7,333
Shutting off equipment for 1 additional hour/day:
Rack Oven =
27,900 kWh
$1,878
Pressure Fryer = 7,058 kWh
$475
Meat Labeler =
7,028 kWh
$473
TOTAL =
41,986 kWh

Closed an extra hour per week
Facilities Philosophy
 Energy reduction is best achieved by front line mechanics educated in how their efforts
affect energy
 Don’t just treat the symptom(s) and walk away
 Fix the problem(s) and remove obstacles to lower energy consumption
 Will include the Team of Mechanics alongside the Energy Team
 Will include the Mechanic assigned to the Store
 Do not just change or lower setpoints and think the job is done
 Be Proactive / Not Reactive (i.e. continually checking Alarms)
CONCLUSION
• 2016 - Dow Jones Stock Index (DSJI)
