CRES — Certified Refrigeration Energy Specialist
CRES was added in November 2013 to assess mastery of refrigeration system operations and energy management strategies. While no other RETA credentials are required to qualify for the CRES credential, CRES candidates do need to demonstrate sufficient knowledge of refrigeration operations to offer energy management strategies without compromising the safety or integrity of refrigeration systems.
CRES candidates should be familiar with the operating concepts and principles addressed in IR-1 in addition to energy management strategies and techniques in the Industrial Refrigeration Best Practices Guide published by Cascade Energy and the Energy Conservation Manual – Industrial Refrigeration Consortium published by University of Wisconsin.
The CRES exam consists of 135 questions and allows three hours for completion.
There is also a performance aspect related to CRES which includes the documentation of three energy saving activities related to refrigeration system operations and their facilities whereby energy savings can be quantitatively documented.
Certification of CRES occurs after successful completion of the exam and documentation of three activities. Additional activities must be documented to maintain CRES certification.
