GreenChill Store
Certification  Program
GREENCHIL
Today's consumers are increasingly concerned about the environmental
impacts of the businesses where they shop. As general awareness of
companies' impacts on the environment spreads, it becomes increasingly important for supermarkets to
proactively demonstrate that they share their communities' commitments to protecting the environment.

Refrigeration and the Environment

A typical food retail store's refrigeration system leaks about one quarter of its refrigerant charge each
year. This leakage accounts for more than one third of a typical food retail store's annual greenhouse gas
footprint (see the graphic below). In addition to the financial expense this leakage represents for a store's
bottom line, refrigerant leaks contribute to climate change and can harm the ozone layer.

GreenChill Certification

The U.S. EPA's GreenChill Advanced Refrigeration Partnership recognizes individual store
achievements in environmentally-friendly, advanced refrigeration with its Store Certification Program
for food retail stores. The program awards either gold-level or silver-level certification to food retail
stores that use green commercial refrigeration technologies  to significantly reduce the store's
environmental impact.

Today's customers want to do business  with stores that share their values. Achieving GreenChill
certification for your store provides recognition and publicity for your company's commitment to
environmental protection. In addition, achieving GreenChill certification for individual stores can be an
effective way to build and sustain store employee morale. Everyone wants to feel proud of where they work!

EPA's GreenChill Advanced
Refrigeration Partnership
Although membership in the GreenChill
Advanced Refrigeration Partnership is
not required to be considered for store
certification, there are advantages to being
a GreenChill partner. The GreenChill
Partnership is made up of industry leaders
in green refrigeration technology and
environmental stewardship. GreenChill is a
cooperative alliance with the supermarket
industry to support and promote green
technologies, strategies, and practices
that protect the ozone layer, reduce
greenhouse gas emissions, and save
money. GreenChill Partners in the food
retail industry have  refrigerant emissions
rates nearly 50% lower than the EPA-
estimated industry average.

The GreenChill Partnership researches
advanced technology and servicing
practices and provides Partners with
tools that can be used to attain corporate
environmental goals. Partners also benefit
from the opportunity to share information
on environmental best  practices and
increased publicity for their commitments
to their environmental goals.

Certification  Process

Certification is available at no cost to food retail stores in
the United States. The process is fast and easy. You simply
fill out a short application with information about the type
of refrigerants used in the store, refrigerant emissions,
and refrigerant charge. There are separate forms for fully
operational stores and newly constructed stores. Once a
store has submitted the appropriate form, EPA will review the
information and confer certification  if warranted.  In general,
the EPA turnaround time for review and certification is brief.
Store certification is awarded for one year and stores can
reapply on a yearly basis. Certification forms, along with
detailed guidance, are available on the GreenChill Web site
www.epa.gov/greenchill/certcenter.html.

Certification  Standards

Food retail stores can achieve either gold or silver-level
certification.

    • Gold Level. The store must use only non-ozone-
     depleting refrigerants. It must also achieve an average
     HFC refrigerant charge of no  more than 1.25 pounds
     of refrigerant per 1,000 BTU per hour total  evaporator
     cooling load and a store-wide annual  refrigerant
     emissions rate of no more than 15%.

    • Silver Level. The store must  use only non-ozone-
     depleting refrigerants. It must also achieve an average
     HFC refrigerant charge of no  more than 1.75 pounds
     of refrigerant per 1,000 BTU per hour total  evaporator
     cooling load and a store-wide annual  refrigerant
     emissions rate of no more than 15%.
