must work with the district energy provider to determine the equipment type, refrigerant type, and refrigerant charge.
For projects that also have refrigerant-containing equipment within the building, the weighted average GWP can be determined using the percentage capacity from each source. For example, if 90% of the energy comes from a DES and 10% from systems on site, teams can apply those percentages to respective DES and on-site equipment weighted average GWP values. OPTION 2. LIMIT REFRIGERANT LEAKAGE
Demonstrate that at least 50% of the combined peak heating and cooling capacity generates on-site. Alternatively, projects demonstrate compliance with the specified criteria for all refrigerant-using systems in the building and all refrigerant-using systems in the district energy system serving the project.

OPTION 3. GREENCHILL CERTIFICATION FOR FOOD RETAILERS
Option 3 offers another path, eligible for up to two points for projects with 20% or more gross floor area of food retail space. Food retail spaces include grocery stores, convenience stores, big-box wholesalers, and general merchandise retailers with large refrigeration sections. Additional spaces may include bakeries, seafood and meat markets, and juice and smoothie bars.
In 2007, the U.S. EPA launched a voluntary partnership program called GreenChill that works cooperatively with the food retail industry to reduce refrigerant emissions and decrease their impact on the ozone layer and climate change. [99] A food retailer achieves Silver-, Gold-, or Platinum-Level certification.
U.S. projects that document GreenChill certification earn points based on the level of certification achieved. International projects must document compliance with each requirement outlined on the EPA GreenChill website for the targeted certification level.
