Project Title 
Low-GWP Refrigerant New Construction Energy Impact Case Studies
Project Number 
Investor Owned Utilities 
Process Loads
Project Year(s) 
2020 - 2023

The project will consist of an assessment of energy and non-energy impacts of moderate-low GWP refrigeration design on three newly constructed supermarkets. Each of the supermarkets will be newly opened and operating as of August 2020 with low-GWP (less than 150) and moderate-GWP systems (less than 1500) prior to the start of this study. Data collection will be limited to post-installation and will be used to quantify energy impacts at each site through a combination of controller trend logs, whole building, and sub-metered 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 strategies at each store relative to a “standard-practice” hypothetical baseline and each of its counterparts.
