Case Study – Sunfresh Foods Freezer Upgrade

October 22, 2020 By SBC staff

Sunfresh Foods Inc. is a small, locally owned company based in Seattle that has coined the term “Freezerves” to describe their signature freezer jam product.

The Sunfresh processing facility is an approx. 10,000 sq. ft. pre-fab concrete building built in the 1970s. Sunfresh wanted to reduce their high electricity bills and identified their extremely inefficient refrigeration systems as the biggest opportunity for improvement. Before beginning the project, they reached out to the Energy Conservation Program at Seattle City Light (the local utility) about possible incentives. City Light was able to provide a substantial rebate, making it cost effective for Sunfresh to upgrade to a new system. The new system achieves high energy efficiency while helping Sunfresh also attain the attendant social benefits of saving energy.

How did the Smart Buildings Center help?
City Light asked Bob Brennand of Energy Smart Industrial (ESI) to help with measurement and verification (M&V) of the actual energy savings to determine the amount of the incentive.

The ESI program, sponsored by Bonneville Power Authority (BPA), helps utility customers and their industrial end-users achieve cost-effective energy savings.

Bob borrowed the Dent ElitePro XC logging power meters from Smart Buildings Center’s Tool Lending Library to measure consumption data after the upgrade, and the results were very impressive.
