Partner Profile
Food Lion, one of the largest supermarket chains in the United States, has more than 1,220 stores in 11 Southeastern and
Mid-Atlantic states.
More than 400 Food Lion stores have achieved the ENERGY STAR label designation and the chain has a portfolio-wide
energy performance
rating above 75. Food Lion became a partner in the US Environmental Protection Agency's ENERGY STAR® program in 1998
and has received ENERGY STAR partner awards in 2002, 2003, 2004, 2005, 2006 and 2007.
Retail Partner Since 1998
Establishing a multi-faceted approach
Energy-use data must be collected and analyzed to help managers spot trends in building and portfolio performance.
Food Lion uses a multi-faceted approach, which includes tracking and analyzing data at both the facility and system levels,
benchmarking energy performance and obtaining appropriate technical assistance.
Food Lions benchmarking program is two tiered. At the macro level, Food Lion uses the ENERGY STAR Portfolio Manager,
which evaluates property and portfolio performance through analysis of Food Lions electric and gas bills.
The Portfolio Manager rates each store and automatically generates scorecards that allow Food Lion to compare stores to
themselves over time, to the rest of the Food Lion portfolio, and to the rest of the grocery industry.
Clave del Éxito
On a more micro level, Food Lion uses a special sub-metering system to
monitor and analyze 17 different loads for each of its stores that have submetering in place. The sub-metering tracks energy consumption in such areas as
HVAC, lighting, Deli, refrigeration, etc. Without sub-metering, a quick look at
Food Lion's utility bill could flag a problem store. However, with sub-metering,
Food Lion can quickly tell, for example, if an energy spike was caused by
refrigeration, HVAC, lighting or any other area. The company's maintenance crews
can then immediately correct the problems and, using the sub-metering system,
know within 15 minutes if the entire problem has been corrected.

Technical Assessment and Audits
Auditing and testing new technologies uncovers savings
To maximize energy performance, Food Lion continually explores opportunities for improvement. Energy
audits and technical assessments help Food Lion identify these operational opportunities. At the heart of
Food Lion's cutting-edge energy program is a commitment to innovation achieved through hands-on
application and testing of existing and new technologies. Food Lion uses benchmarking to identify
high-energy-use stores and sends in-house Energy Field Specialists to perform a High Utility
Checklist. This checklist is used to verify that all set points in regards to HVAC, lighting, deli
equipment and refrigeration are correct at the store. Stores that underwent energy audits experienced
reductions in energy consumption as great as 12 percent after the checklist was completed.
Food Lion also tests technologies to identify those stores that offer the greatest potential for energy
savings. For example, in 2004, Food Lion tested technologies including skylights coupled with
dimming sensors to practically eliminate daytime electric lighting of the back room; anti-fog film to
replace anti-moisture heaters in glass cases; and high-efficiency case motor fans.

Motivación a empleados
Set Goals
Food Lion uses several levels of goals to continuously improve its energy
performance. Food Lion has set a long term goal to "Become one of the most
efficient grocery stores in the world on a Btu per square foot basis." To achieve
this, Food Lion set an organization-wide annual goal of reducing energy
consumption by 300 billion Btus for 2003
Motivate - Rewarding Maintenance Staff
Food Lion's Energy Awareness Plan rewards maintenance staff by awarding
quarterly bonuses for improving energy performance. Keeping maintenance staff
motivated to save energy has helped Food Lion reduce its utility cost per store
per week by 5.5 percent.
Ejemplos de ROI
En muchos casos el Retorno de la Inversión
toma varios años. Si por Ej. ‘Supermercados
Grande’ gasta $130,000 en iluminación de alta
eficiencia en 2008, esto le ahorraría al
supermercado $22,000 al año en electricidad
y gastos de mantenimiento
€
ƒ
ƒ
El “payback” o retorno de inversión seria de 6
años. Como el costo de electricidad aumenta, los
ahorros aumentarán y eso puede llevar a reducir
el retorno de la inversión.
También se puede hablar de un ROI de 17%
Los “low hanging fruits” en Ahorro de
energía en supermercado

Sobre el 50% de la energía útil en los motores se
puede ahorrar cambiando motores con mas alta
eficiencia.
Iluminación debe de ser de Ballast T-5 y T-8 en vez
de T-12. Ahora mismo el T-5 ahorra mas.
Humedad en exceso
Reduciendo la humedad en los
supermercados reducirá las
cargas de calor latente en los
sistemas de refrigeración y
equipos de aire acondicionado.
Sistemas actuales han
demostrado tener 13% de
ahorro de la energía usada.
Alta humedad causa
congelación excesiva en los
coils de los evaporadores
reduciendo la transferencia de
calor y así la eficiencia. Los
“heaters” mantienen la
superficie de los sistemas de
refrigeración sobre el punto de
Dew Point para que el
condensado no se forme.

Para las neveras se puede apagar los “door de-foggers” hasta que se necesite

Uncontrolled, anti-sweat heaters found in glass display doors
and refrigerated cases run 24 hours, 7 days a week to prevent
condensation on the glass and frames, allowing a clear view of
the displayed products.
The Door Miser significantly reduces the runtime of the antisweat heaters, SAVING the retailer money!
Door Miser Technology Door Miser uses a patented digital
moisture sensor technology that detects moisture at the
microscopic level, and then sends a signal to its controller that
activates the anti-sweat heaters. Once the threat of condensation
is eliminated, Door Miser automatically shuts off the anti-sweat
heaters.
