Members of the Hatfield Township community place a high value on locally sourced and organic foods and environmental stewardship. As such, planning for the town’s new ShopRite supermarket included making sustainability a priority from product offerings to construction of the store itself — including the choice of refrigeration systems and display cases.

In late 2010, Sprouts Farmers Market set out to meet the EPA’s most stringent GreenChill standards with construction of its Thousand Oaks, Calif., store. Sprouts tapped Hill Phoenix to design a refrigeration system that not only would be environmentally friendly, but also energy efficient and cost effective to install and maintain.

The supermarket chain Hy-Vee Inc.’s 64,000-square-foot store in Fairfield, Iowa, opened on April 12 as the company’s second Leadership in Energy and Environmental Design (LEED)-certified store. It is one of the few supermarkets in the country that has achieved U.S. EPA GreenChill Gold-Level certification.

Centralized refrigeration systems have been in use for years. Distributed systems, on the other hand, are one of the newer commercially adopted refrigeration technologies.

I take issue with Carrier Corp. requesting the EPA to prohibit manufacturing of dry R-22 condensing units.
