Model Regulation Guidelines for Energy-Efficient and Climate-Friendly Commercial Refrigeration Equipment Supporting Information

This document provides context on the rationale underpinning the U4E Model Regulation Guidelines for Energy-Efficient and Climate-Friendly Commercial Refrigeration Equipment (Guidelines). It includes an explanation to the extent possible of the scope, product categories,
and market and policy trends in energy consumption and refrigerants of commercial refrigeration equipment. Section 1 presents an overview of the global commercial refrigeration market and policies. Section 2 discusses the scope of the Guidelines. Section 3 assesses technologically feasible energy-efficiency improvement options, adoption trends of such options, and the cost-effectiveness of these options on the energy consumption of two equipment types. Section 4 analyzes energy performance requirements in the Guidelines and leading economies. Section 5 addresses lower global warming potential (GWP) refrigerant options. The Guidelines refer to international standards (e.g., ISO 23953 for Performance and Energy Rating of Commercial Refrigerated Display Cabinets). Officials should be familiar with either the referenced standards or other established approaches to effectively utilize this information.
