Low-GWP Refrigerant Remodel Energy Impact Case Studies

Project Number ET21SCE0012 Organization SCE End-use Process Loads Sector Commercial Project Year(s) 2020 - 2023
The project will consist of an assessment of energy and non-energy impacts of low-GWP retrofits on three supermarkets. Each of the three supermarkets are scheduled to upgrade their existing systems, replacing traditional HFC refrigerants with low-GWP (less than 150)  and reduced charge moderate-GWP systems (less than 1500). Data collected pre- and post-retrofit will be used to quantify energy impacts at each site through a combination of short-term logging, spot measurements, controller trend logs, and whole building energy consumption data. This data, and observations at sites will be used to calculate end use consumption of the primary systems and assess the impact of various design changes at each store.
