Given the importance of Commercial Refrigeration to meeting future energy savings, BPA began exploring ways to track this energy consumption to better inform measure development. In 2012, the Energy Efficiency Engineering team became aware of a refrigeration performance monitoring system – Climacheck - and decided to use the equipment to monitor commercial refrigeration systems in the BPA region.

BPA’s Next Steps
- Provide the data to the RTF to update assumptions in refrigeration UES measures for values of EER (Energy Efficiency Ratio, Btuh/W) and Average Annual Load to Design Load Ratio.
- Provide data to be used in future regional end use loads analyses.
- Identifying new measures and refining program offerings.
- Identifying future research projects to address performance anomalies.
- Creating new commercial refrigeration system commissioning programs.
