FMI Energy: EPA GreenChill recognizes ALDI US for most certified stores

The chain received platinum-level certification for 81 transcritical COstores in the past year; it has more than 200 COstores overall.

The U.S. Environmental Protection Agency’s GreenChill Partnership today recognized ALDI US with its store certification excellence award for achieving more GreenChill store certifications, all at the platinum-level, than its peers over the past year. 

Also receiving the award was Hillphoenix for supplying more GreenChill-certified stores with refrigeration equipment than any other manufacturer over the past year; the OEM was given the award for the eighth consecutive year.

GreenChill certifies individual stores at silver, gold and platinum levels for limiting refrigerant leaks and charges to designated levels or for employing advanced refrigeration systems.

The GreenChill program handed out these and several other awards at its annual awards breakfast and ceremony today the Food Marketing Institute (FMI) Energy & Store Development Conference. Tom Land, manager of the program, announced his retirement after hosting the ceremony.

According to Land, in 2018 ALDI US, based in Batavia, Ill., had 81 certified stores in 2018 while Conyers, Ga.-based Hillphoenix supplied equipment to 204 certified stores. All of ALDI US’s certified stores employ transcritical CO2refrigeration systems; Hillphoenix is a major supplier of transcritical CO2 equipment to ALDI US. 

Amber Hardy, director of energy management for ALDI US, noted that the chain has installed transcritical CO2 systems in more than 200 stores, the most of any retailer in the U.S.; many of its stores have 8-10 self-contained R290 cases, she added.

Launched in 2007, the GreenChill program helps U.S. food retailers reduce refrigerant leaks and charges while enabling many to adopt natural refrigeration systems. GreenChill Partners, had an average leak rate of 13.9% in 2018, said Land; they emit at least 65% less refrigerant than the average supermarket, according to the EPA. 

Over the past decade, participation in the GreenChill Program has grown from 4,500 stores to over 11,000 stores nationwide, representing about 29% of the U.S. supermarket industry.

Other award categories and winners included:

Best Emissions Rate: 

Harris Teeter, Matthews, N.C., achieved the lowest refrigerant emissions rate among retail supermarket chains last year. Cook County Whole Foods Co-op, Grand Marais, Minn., received this recognition for the category of small-independent grocers. In 2018, 12 GreenChill retailers achieved emissions rates under 10%, said Land.

Most Improved Emissions Rate: 

Hanover Co-op Food Store, Hanover, N.H., has documented the largest refrigerant leak rate reduction compared to the year it joined GreenChill. McQuade’s MarketplaceWesterly, R.I., lowered its emissions rate more than any other GreenChill partner compared to the previous year.

Goal Achievement

GreenChill’s five “Superior Goal Achievement” award recipients voluntarily set and achieved their corporate goal for reducing refrigerant emissions. Recipients include Hy-Vee, West Des Moines, Iowa; King Kullen, Bethpage, N.Y., Price Chopper, Schenectady, N.Y., Raley’s, West Sacramento, Calif., and Sprouts Farmers Market, Phoenix, Ariz. Hy-Vee, King Kullen, and Sprouts Farmers Market also earned “Exceptional Goal Achievement” for meeting an even more stringent “stretch” goal to reduce refrigerant emissions.

Distinguished Partner

Hy-Vee received this recognition for leadership through active participation and initiative in achieving GreenChill goals.

Best of the Best

Target, Minneapolis, Minn., was honored as “Best of the Best” within GreenChill’s store certification program for installing micro-distributed stand-alone refrigerated cases in multiple small-format stores. The retail chain has installed these cases, typically using R449A and a water-loop heat removal system, in 21 stores, “with a number in the works,” said Erich Schwab, lead mechanical engineer, refrigeration engineering and store design for Target. 

“We would like to move to R290 [propane]" in these stores  when the U.S. adopts higher charge limits for R290 cases, added Schwab. The U.S. and other countries are considering adopting a new global charge limit standard, which was increased this year by the International Electrotechnical Commission (IEC) to 500g from 150g. “Five hundred [grams] would be better; we could probably work with 300,” he said. Target uses up to 150g of R290 in spot merchandisers throughout its 1,800-store chain.

Store Re-Certification

Weis Markets, Sunbury, Pa., operates a store in Hanover, Pa. that was recognized as the first supermarket in the U.S. to be GreenChill-certified for 10 consecutive years. Eight stores were recognized for achieving GreenChill certification for five consecutive years. Sprouts Farmers Market achieved this honor for stores in Birmingham, Ala.; Lakeland, Tenn.; Madison, Ala.; Mansfield, Texas; Peoria, Ariz.; Scottsdale, Ariz.; and two stores in Kansas City, Mo.

“We applaud the supermarket chains for their environmental leadership in minimizing refrigerant emissions and their adoption of advanced refrigeration technologies,” said Anne Idsal, acting assistant administrator for EPA’s Office of Air and Radiation. “They’re not just protecting the environment; they’re keeping costs down for themselves and their customers.”
