ENERGY STAR Commercial Food Service (CFS) Equipment
January 2010
• Voluntary climate protection partnership with EPA
• Strategic approach to energy management, promoting energy efficient products and practices
• Helps organizations save money and protect the environment
• Influential brand recognized by over 75 percent of Americans
What is ENERGY STAR?
ENERGY STAR Specification Process
• Stakeholder involvement - including manufacturers, utilities, environmental groups, and other government agencies
• Iterative process• Use or develop test methods• Designed to recognize top 25%
Benefits of ENERGY STAR Equipment
• End-users save energy, water, and money
• ENERGY STAR qualified products use innovative and energy-efficient technologies, improving performance through:– Shorter cook times– Higher production rates– Improved insulation
• Reducing HVAC use due to cooler kitchen– More efficient components, such as compressors
• Ask your manufacturer for more details– Training– Marketing materials– Financing options
Acquisition costs are just the tip of
the iceberg
Maintenance and other ongoing costs
(can be 2-20 times greater)
